 Keep proof of ownership separate from validity, editability, and readiness. Malformed owned data may still be safely removable. Unresolved identity or applicability must remain unknown rather than be treated as absent, foreign, or aligned.

+For lifecycle changes, follow [ownership and completion invariants](docs/tool-design.md#own-the-lifecycle) and select the applicable [lifecycle regressions](docs/testing.md#lifecycle-regressions). Include late handshakes, cancellation during final cleanup, mixed child outcomes, and cleanup retry where those stages exist; active-execution cancellation alone does not cover finalization.

 Assess brittleness in touched code during implementation, debugging, review, and maintenance. Fix the producing representation or ownership rule before adding downstream repairs. Normalize once at the owning boundary using format-aware parsers. Remove superseded representations, aliases, wrappers, and redundant tests after verifying affected consumers. Introduce abstractions only when they remove observed complexity.

 When fixing a bug, inspect the producing boundary and affected consumers for duplicated interpretation or unclear ownership. Complete any directly related refactor in the same change and remove superseded code. Passing regression tests alone does not establish that the brittleness is resolved. If related cleanup remains, explain what remains and why.

 `details.partial_observation` and marks their application cleanup `unverified`.
 Cleanup uncertainty does not authorize signaling unrelated processes.

+Main-process IPC recording keeps original-function removal for `on` and `once`
+registrations and records a fired `once` callback once. Native Node.js owns
+`once` registration, firing and callable dispatch as well as removal order and
+traversal, including listeners registered by removal observers;
+the hook translates only its own recording wrappers at the removal boundary.
+Wrapper metadata uses weak keys and does not retain removed registrations.
+Wrapper metadata operations, private collection methods and traversal constructors are captured
+before target startup; later replacement of their global bindings does not
+change listener registration or removal.
+
+Native runtimes differ in whether `once` consults callback `.call` or `.apply`.
+The hook observes actual callback entry without imposing another runtime's
+property reads or argument-list representation. Application methods selected by
+native dispatch keep their original receiver and argument-list object; opaque
+methods produce a `custom-call` or `custom-apply` observation gap when callback
+execution cannot be established.
+
+If native wrapper creation or registration-method lookup could expose private
+instrumentation through an application getter, setter or Proxy, registration
+stays native and unwrapped. The `once-metadata` observation gap identifies that
+unobserved registration attempt; it does not prove registration or delivery. The original callback,
+metadata writes and native method receivers are preserved, including when
+registration fails. Later registrations resume normal observation. Non-callable
+`call`/`apply` properties produce failed observation gaps when native dispatch reads
+them; callback entry is not fabricated.
+
+An `on` listener's application-defined `.apply` receives the original argument-list
+object unchanged. Borrowing the exposed method preserves its dynamic receiver.
+Because that method owns argument interpretation and may not
+invoke the callback, the hook records a bounded `ipc-observation-gap` timeline
+entry with the registered channel rather than an IPC invocation. Its empty
+`argument_shapes` means unobserved arguments, not a zero-argument callback;
+callback execution and result remain unknown. Coverage and retention include
+these gaps even when their individual records are dropped. Normal native
+dispatch continues to record actual invocation frames. Evidence snapshots copy
+retained arrays and counters without invoking application iterators or Array
+species.
+
+Listener-chain recognition distinguishes owned, unowned and unknown metadata.
+Data links may be inherited; absence is established only after completing the
+bounded prototype lookup. Exhausting either walk, encountering a getter or seeing a Proxy leaves
+ownership unknown. The hook preserves native registration without adding another
+recording wrapper and retains a `listener-chain` observation gap after successful
+registration. This gap does not prove IPC delivery. An existing inner recording
+wrapper can still report its actual invocation; otherwise callback activity
+remains unobserved. Setter-only properties have a known undefined read.
+Data-descriptor parsing is shared with removal normalization.
+
+This does not establish complete JavaScript function introspection equivalence.
+Caller-defined `.listener` properties can change the identity exposed by
+`listeners()` and meta-events; accessors and Proxy metadata are not followed for
+wrapper recognition. Re-registering a raw recording wrapper on another channel
+retains the original registration's channel attribution.
+Mutating `.listener` on a raw recording wrapper can also prevent removal through

+the affected owners and applicable scenarios below. Include temporary snapshots
+and one-shot commands. Use public CLI/MCP workflows where practical and a
+controlled production seam for interleavings that cannot be reproduced reliably.

+
+Synchronize cancellation with the finalization boundary being tested; a fixed
+delay after dispatch does not establish that phase. Use markers, barriers, or
+owned cleanup seams while preserving real cleanup where feasible. Check server
+settlement and retained resources even if the MCP SDK rejects the client promise
+before the handler finishes. A cancellation during active execution does not
+cover cancellation during final cleanup.
+Use explicit abort reasons and assert their identity at admission and after
+provider completion, alongside retained observations and cleanup state.
+
+For atomic writes, exercise cancellation on both sides of the documented commit
+point and preserve any publication receipt. A late interruption does not prove
+that no output was published.
+
+For successful provider reports, test cancellation immediately before the report
+reaches the application workflow as well as during provider cleanup. Validate
+the report before classifying completion: a valid report must retain its Evidence
+on cancellation, and an invalid report must keep its output error. Exercise both
+the provider boundary and the shared CLI/MCP workflow; a downstream guard does
+not repair the provider's own completion contract. When callers share startup,
+cancel each waiter independently and verify that the last departure awaits owned
+cleanup while interested peers can still reach readiness. Repeat the same
+shutdown event after a cleanup failure to verify that its listener can retry.
+Exercise non-default lifecycle deadlines through queued requests and their
+consumers; default-only controls cannot detect dropped request options.
+
+For descriptor-backed reads, inject a close failure after a successful read and
+after a primary read or cancellation failure. Verify that the exact descriptor
+remains owned, both failures survive, and a later close retries it. Repeat
+admission attempts while close still fails: no additional descriptor or
+native command should start. Restore close and verify that the exact owner
+resolves the originating cleanup marker and allows later work, while the earlier
+failure remains available as a diagnostic. Retain errors returned by multiple
+failed retries, including admission and shutdown aggregates, and assert that
+each becomes complete after recovery. For an aggregate with multiple owners,
+release one owner while another still fails and assert that it remains incomplete.
+Cover recovery before the
+caller-specific error is bound to its retained owner, as
+another request can retry cleanup concurrently. Confirm that an already released
+owner resolves a later binding too. Include
+admission failure after opening the descriptor. If caller cancellation returns
+before an inspection settles, gate its final read or close and verify that
+session shutdown waits for the owned work and reports any retained resources.
+Gate a later read in a multi-read inspection, not only its first read. Overlap
+operations so one retains a failed descriptor while another reaches its next
+read; both the operation and shutdown must settle without nested-admission
+deadlock. Deny child close and verify its containing root survives until retry.
+
+Exercise publication on filesystems without hard links using an unsupported-link
+seam. Check exclusive destination creation, stat/write/close failures, completed
+output receipts, and cancellation at the documented cutoff. A streamed fallback
+has different visibility from an atomic hard-link commit and must report it
+accurately. For Windows command supervision, keep a descendant writing after its
+leader exits, deny cleanup observation, and verify a competing writer remains
+excluded until the exact Job Object closes. Portable doubles cover retry logic;
+the native Windows lane must establish actual process-tree behavior.
+
+Supervisor tests must observe process exit, output-pipe closure, and IPC
+disconnection separately. In the pinned Node runtime, a parent-initiated IPC
+disconnect can omit the aggregate `ChildProcess` close event. Join the actual
+resource observations before reporting completion; process exit alone does not
+establish pipe or process-tree release.
+
+When changing an internal helper contract, check its JavaScript verifier and
+subprocess-script consumers alongside TypeScript references. Source typecheck
+does not check those calls; run their orchestration tests against the built
+modules, including the verifier's failure and cleanup paths.

+## Own the lifecycle
+
+For tools that acquire resources, identify the owner and the observations that
+establish each transition. Include temporary files and one-shot commands, as
+well as persistent engine sessions. Use the existing provider contracts;
+providers need not expose identical state machines.
+
+- Keep target admission, provider readiness, active work, observed process exit,
+  and resource release separate. A valid process handle, successful launcher,
+  or selected target establishes only its own fact. Publish available identity
+  and exit observations even when launch fails; retain unknown ownership.
+- Authenticate and capture identity through the same boundary on initial and
+  recovery handshakes. Bound abandoned unauthenticated listeners where the
+  protocol permits it; that deadline must not expire authenticated idle sessions
+  or long-running native work. Listener expiry does not prove target closure.
+- Readiness observations may await owned prerequisite commands. Status must
+  remain readable during owner finalization without starting replacement work;
+  report readiness as unknown when it cannot be re-observed.
+- Shared startup has one producer and independently cancellable caller waits.
+  Keep it running while any caller still needs it. The final departing caller
+  waits for owned cleanup and retains its failure. Provider closure is distinct
+  from caller cancellation. Retained cleanup capabilities block replacement;
+  derive readiness from the current startup's completion and live connection.
+- For cancellable observations, carry cancellation through result consumption
+  and awaited cleanup. Before returning success, check the signal after the
+  last awaited finalization step.
+  Retain collected observations under typed cancellation. Preserve an existing
+  primary failure and let incomplete cleanup retain its own classification.
+  Preserve the caller's abort reason as the typed cancellation error's cause,
+  including when cancellation is observed only after provider completion.
+  Shared command owners must retain the observed cancellation reason separately
+  from physical failures and cleanup ownership. Carry that fact through failure
+  wrapping so adapters can preserve the exact reason without interpreting it.
+  Client cancellation alone does not prove native work stopped.
+  For atomic publication, document the cancellation cutoff and preserve any
+  committed output's publication receipt.
+  Queued and retried work must retain the complete accepted execution controls,
+  including non-default lifecycle deadlines and cancellation signals.
+- Release only owned resources. Attaching owns a connection or session unless
+  the provider contract explicitly establishes target ownership. A helper exit,
+  missing reply, or missing PID does not establish target exit.
+- Retain successful child cleanup and retry only unresolved children, including
+  when close options change. Preserve observed child failure or activity when
+  another child's health is unavailable; idle plus missing coverage stays
+  unknown.
+  Bind cleanup failures to their exact resource owner. Resolve current cleanup
+  uncertainty only after that owner confirms release, while preserving the
+  original failure and completed observations. Later failure composition must
+  report only resources whose cleanup remains unresolved. Carry cleanup
+  capabilities explicitly in typed outcomes so consumers can bind returned errors
+  to exact owners without reparsing diagnostic cause chains.
+  Bind every caller-visible retry error and aggregate, including an error already
+  produced by the provider. An aggregate remains incomplete until all owners it
+  reports are released; releasing one child cannot clear another child's status.
+- Await one-shot cleanup without discarding the completed result or primary
+  diagnostic. Preserve partial observations, remaining resources, and the cleanup
+  owner's recovery instructions. CLI adapters should reuse
+  [`finishAnalysisCommand`](https://github.com/morluto/rea/blob/main/src/cli/finishAnalysisCommand.ts) where its contract
+  applies rather than duplicate close/finally handling.
+- Give descriptor-backed reads an owner before opening the file. A rejected
+  close must retain the exact handle and preserve any earlier failure. If an
+  abortable caller stops waiting, keep the underlying work in that owner's
+  lifetime so shutdown cannot report release before finalization settles.
+  Admit the entire inspection once, including later reads and finalization.
+  Helpers must borrow that admission or use an operation child scope; re-entering
+  the same draining scope can make cleanup wait for its own caller.
+  Retry retained cleanup before admitting new work and keep admission blocked
+  while it remains unresolved. Link the originating cleanup error to its exact
+  owner so confirmed release resolves its cleanup marker while preserving the
+  earlier diagnostic. Shared CLI/MCP adapters cannot infer that confirmation.
+- Provider profile selection owns every asynchronous candidate through its
+  terminal result and finalization. The registry owns profile-file cleanup,
+  joins all automatic-selection children, and closes those file owners before
+  reporting candidate shutdown. Final caller cancellation joins the selection;
+  an adapter that ignores cancellation remains active and owned until it settles.
+  Block new admission during shutdown and while cleanup remains unresolved;
+  reopen after confirmed retry. Preserve failed results before considering a
+  later signal, and retain every child's attributed cleanup in mixed outcomes.
+- Release child descriptors before removing their containing root. Retain a
+  composite owner when either stage fails so retry preserves that ordering.
+  A Windows command leader's exit does not establish Job Object closure. Keep
+  the process-tree observer and command lock alive through failed cleanup retries
+  until the owned tree's close event.

+[#4027](https://github.com/morluto/rea/issues/4027).
+
+The cancellation boundaries and retained cancellation cause are verified below.
+The complete real Linux Joplin workflow remains **partial or failed** because
+process ownership/cleanup cannot be verified. Publishing a typed reply, exiting
+the CLI, and cleaning up its application are separate observations.
+
+## Source and deterministic regressions
+
+Latest-main control is `fe2a398dd9ab290ba6cb3411403d319cec8d07a2`.
+The existing reviewed PR head `af732dd8` was integrated with that main in
+`3b094802a`. Its initial 47 focused cases passed. An unrelated compact-catalog
+test hit its unchanged 10-second CI deadline; an unchanged-source job retry
+passed. The original failed execution remains in CI history.
+
+Real CLI verification exposed an introduced regression: the PR replaced an
+already observed cancellation with success after the final snapshot. A later
+cleanup failure then lost the cancellation category and caller reason. Two
+deterministic cases reproduced this for process and transport cleanup: 20 old
+cases passed and both new cases failed. Main's public reply retained category
+`cancelled`; the reviewed PR returned `execution_failure` for the same kind of
+cancelled wait plus incomplete cleanup.
+
+Fix `73d4a712b` records cancellation before finalization and uses one constructor
+for the early and late partial-capture errors. Cleanup failure keeps precedence,
+its diagnostics and the earlier cancellation cause. Cancellation first observed
+during cleanup retains the existing precedence. The fix changes the producing
+outcome; no CLI/MCP projection repair or ownership-policy exception was added.
+
+All **49 focused cases in three files** passed after the fix. Full static checks
+passed: six tasks plus architecture guards. Documentation checks also passed
+(six tasks, including two cached, plus five README consistency cases). One intermediate build rejected an
+over-narrowed `aborted === true` comparison; the original truthiness pattern
+resolved that TypeScript error before the passing build. Recorded catalog
+metadata is byte-identical to main. No new tool, schema, cache or normal-case
+result field was added.
+
+## Real application observations
+
+The unchanged official Joplin 3.7.21 ASAR is 233,575,014 bytes, SHA-256
+`767df409b18effe60421fbefcca873de237c7e813eac744ecdeebbc5e825a33a`.

+| Fixed: final snapshot reply stays pending   | Cancellation returned in 10.262 s; five-second cancellation grace expiry and initial snapshot retained |
+
+Every fixed case preserves the `cancelled` category. Every real case still has
+unverified provider cleanup and a nonzero verifier exit; these are cancellation
+phase proofs, not complete runtime passes. The known Linux ownership gap is
+tracked in [#4282](https://github.com/morluto/rea/issues/4282). Ownership was not
+inferred from process names, PIDs or executable paths to make these tests pass.
+
+The public CLI trials send SIGTERM after actual Joplin startup logging. Main
+and the fixed version both publish `cleanup_incomplete` with category `cancelled`
+and a cancelled action. The fixed reply was observed about 5.268 s after SIGTERM
+(50 ms polling resolution). Both fail the verifier's 20-second first-signal exit
+deadline and require a second, explicitly recorded recovery signal. The resulting
+143 exit is not proof that the first signal completed cleanup.
+
+The official packaged Joplin executable also passed static fuse admission, but
+its initial Inspector evaluation failed with a destroyed execution context before
+the cancellation condition was reached. Those attempts remain failed diagnostics;
+they establish no bundled-runtime compatibility or cancellation result.
+
+## Costs, limits and reproducibility
+
+Costly operations run serially on one CPU 10 with an 8 GiB hard limit, 6 GiB
+early stop, no swap and 192 tasks. The passing static gate used 153.534 s wall,
+152.274161 family CPU seconds and 6,442,016,768 peak cgroup bytes. It reported
+no OOM and verified payload cleanup. Cgroup memory includes file cache, not RSS.
+Other trials' exact counters and failures are preserved in the
+[compact record](electron-cancellation-2026-10-16.json).
+
+Payload-exit counters are collected while the observer remains alive and are
+not final whole-scope counters. Some failed probes retain live app/Xvfb processes
+at that point. Every recorded scope was independently confirmed inactive/dead
+after the external owner stopped it. That recovery does not establish successful
+provider cleanup.
+
+OS/build caches are uncontrolled. A timed-out baseline and a partial fixed
+workflow do not establish a completed-task speedup. Live event sets also differ,
+so reply-size differences do not establish token savings. Model billing, peak
+agent context and complete host/tool-schema token costs are unmeasured. Historical
+diagnostic helper hashes were not captured at execution; the record marks that
+gap instead of assigning the later frozen hash to earlier runs.
+
+Build each pinned checkout, then run under the existing
+[resource observer](../../experiments/analysis-efficiency/resource-counters.md)
+and a private Xvfb instance. The shared verifier supports all four named cases:
+
+```sh
+node experiments/analysis-efficiency/electron-cancellation.mjs \
+  --runtime-root /absolute/pinned-checkout \
+  --executable /absolute/electron-44.7.0/electron \
+  --application /absolute/Joplin/resources/app.asar \
+  --profile-root /absolute/temporary-profile-parent --case window-wait
+```
+
+Use `initial-state`, `final-state` or `normal-wait` for the other boundaries.
+The public CLI probe has no injected stalled reply:
+
+```sh
+python3 experiments/analysis-efficiency/joplin-cli-cancellation.py \
+  --node /absolute/node-24.18.0/bin/node --runtime-root /absolute/pinned-checkout \
+  --executable /absolute/electron-44.7.0/electron \
+  --application /absolute/Joplin/resources/app.asar \
+  --profile-root /absolute/temporary-profile-parent
+```
+
+The scripts return failure rather than claiming complete cleanup when the real
+owned app remains unresolved. App binaries, extracted runtimes/profiles and raw
+large output are regenerable and are not committed. No macOS, Windows, full
+Joplin GUI or live-model success is claimed.
+
+## Review follow-up: verifier exit semantics
+
+Review of `beb4a47db` found a verifier false pass: the shared probe could exit
+successfully once its main process had exited even though provider cleanup was
+still unverified. The CLI probe also accepted `cleanup_incomplete`. Those are
+verifier bugs; they do not invalidate the recorded failed Joplin trials above.
+
+Revision `227217ac3` requires verified provider cleanup in both probes and the
+public `cancelled` category in the CLI. Six controlled oracle cases cover an
+exited main process with incomplete cleanup, complete cleanup, transport failure
+after process cleanup, and a wrong public category. Both old scripts fail these
+regressions; the fixed scripts pass all six. These cases substitute provider/CLI
+replies and do **not** establish real-provider compatibility or performance.
+
+The fixed, frozen scripts were then rerun on the same real Joplin artifact. The
+shared window-wait probe retained cancellation in 5.577 s and explicitly failed
+because cleanup remained unverified. The public CLI retained category `cancelled`
+and a cancelled action, published its reply about 6.335 s after SIGTERM, and
+again failed the first-signal exit deadline. Both verifiers exited nonzero; their
+externally owned scopes were stopped separately. Production source and the
+earlier historical records are unchanged. The compact record appends these
+observations under `review_followup`.
+
+Run the controlled oracle regressions separately from the real-app commands:
+

+# Electron IPC listener verification, 2026-10-16
+
+[#4390](https://github.com/morluto/rea/issues/4390), existing
+[#4389](https://github.com/morluto/rea/pull/4389), umbrella
+[#4027](https://github.com/morluto/rea/issues/4027).
+
+All 73 IPC boundary regressions pass, alongside shared projection/actions and
+converted MCP schema checks. Real draw.io operation phases succeed.
+Every real capture still **fails overall provider cleanup**. These are distinct
+results; neither completed-task acceleration nor token savings is established.
+
+## Producing boundary and regressions
+
+The existing PR `efd452948` was integrated with main `180ba03bf` in `5c3b02468`.
+It fixes removal through the caller's original function and duplicate recording
+of `once` invocations. Independent review found two further producing-boundary
+problems: wrapper recognition evaluated caller `.listener` getters, and a copied
+`removeAllListeners` snapshot loop differed from native live-array traversal when
+removal observers prepended a listener.
+
+Both new differential cases failed on that implementation (14 passed, two
+failed). Fix `3c330f259` delegates traversal to Node, translating only owned `on`
+wrappers at `removeListener`, and preserves the `off` alias. Descriptor reads
+avoid evaluating getters. A further Proxy case exposed that descriptor reflection
+can itself run a trap (16 passed, one failed); `2fb7f5523` uses Node's Proxy
+identity first and removes the superseded catch. Those initial **17 cases** pass;
+the later decorator finding and final 23-case validation are recorded below.
+The native EventEmitter controls are semantic regressions, not real-app proof.
+
+The change uses weak wrapper keys, removes the copied traversal and its snapshot
+allocation, and adds no tool, cache, schema or normal reply field. Related
+compiled provider/service modules and catalog metadata were byte-identical to
+baseline main `180ba03bf` at the initial source freeze. This does not prove
+arbitrary function introspection equivalence: custom
+`.listener` properties and raw wrapper re-registration retain the limitations
+documented in [Electron observation](../electron-observation.md).
+
+## Unchanged real application and observed scenario
+
+Official [draw.io Desktop 32.4.1](https://github.com/jgraph/drawio-desktop/releases/tag/v32.4.1)
+AppImage SHA-256 is
+`c687a9f1ddcaa146b78547452d264c03c2afcf125639cba5deeb65f3e9554c9e`;
+both the release asset digest and published checksum file match. Its unchanged
+62,941,673-byte ASAR is
+`e64b9650c0b8241ca9a7d33b56386a385bceee63270cec701d3a467347b697e6`.
+Complete accompanying resources were extracted; no application source was edited.
+
+Public fuse inspection reports the official executable's Inspector fuse disabled.
+No vendor Inspector attempt was made. The following trials explicitly select
+generic Electron **44.7.0**, Xvfb and fresh profiles; they establish no packaged
+runtime compatibility.
+
+The real renderer initially displays an **Invalid file data** dialog. A public
+CLI startup smoke and independent DOM/argv probes preserve this failure, tracked
+separately in [#4494](https://github.com/morluto/rea/issues/4494). Its exact cause
+is not proven. Two attempts to click a palette item without handling the dialog
+timed out and were cancelled; they remain failed diagnostics. An initial helper
+also incorrectly queried `application.process()` after transport closure; the
+corrected helper retains the original ChildProcess handle instead.
+
+The final scenario uses declared REA clicks to dismiss that actual error and
+insert a visible palette item, then waits for rendering. Independent DOM reads
+confirm SVG elements **0 → 2**, disappearance of the error and the real unsaved
+changes indicator. The verifier exercises the real app callbacks and channels;
+the production hook wraps their registration as described above.
+The source also registers `app-load-finished` through both `once` and `on`;
+recording its once callback twice adds a spurious event.
+
+## Initial fixed-source ABBA observations
+
+Verifier/source revision is `d02cc934c`; its hashes were recorded before all four
+trials. Baseline is main `180ba03bf`. The same script, runtime, artifact and
+declared actions run in the order baseline, candidate, candidate, baseline.
+
+| Variant/run | IPC events | `app-load-finished` | SVG change | Pipeline wall s | Family CPU s | Peak cgroup bytes |
+| ----------- | ---------- | ------------------- | ---------- | --------------- | ------------ | ----------------- |
+| Baseline 1  | 8          | 3                   | 0 → 2      | 11.084          | 6.270053     | 560,615,424       |
+| Candidate 1 | 7          | 2                   | 0 → 2      | 11.135          | 6.395461     | 550,383,616       |
+| Candidate 2 | 7          | 2                   | 0 → 2      | 11.898          | 6.907123     | 525,631,488       |
+| Baseline 2  | 8          | 3                   | 0 → 2      | 11.469          | 6.526674     | 558,456,832       |
+
+Every declared action completed, every insertion oracle passed, and no verifier
+deadline fired. Every provider returned `cleanup_failed`; the captures remain
+partial/failed, including possible dirty-editor teardown and the known Linux
+ownership gap [#4282](https://github.com/morluto/rea/issues/4282). Baseline 2 also
+reports Xvfb temporary-directory cleanup failure (payload exit 5). Its directory
+identity was not captured; no broad path-based deletion was attempted.
+
+Runs are serial on CPU 10 with one-CPU quota, 8 GiB hard memory, 6 GiB early
+stop, no swap and 192 tasks. Counters cover the cgroup family at payload exit
+while the observer remains alive; they are **not final whole-scope counters**.
+Memory includes file cache, not RSS. Some scopes still contain Xvfb at that
+point; all recorded scopes were later independently confirmed inactive/dead.
+External recovery does not establish provider cleanup.
+
+OS/build caches are uncontrolled; these are first/repeat fresh-process runs,
+not verified cold/warm system pairs. Two samples per variant and a cleanup-bound
+failed workflow cannot establish a speedup. Token billing, peak agent context,
+complete schema/call costs and actual MCP-wire parity are unmeasured. Fewer
+events alone do not establish lower token cost.
+
+Full static checks passed (two tasks, no cache hits): 89.441 s wall,
+88.630288 family CPU s and 4,337,172,480 peak cgroup bytes, with no OOM.
+Documentation checks also passed (6 tasks plus five README consistency cases).
+The [selected JSON record](electron-ipc-listeners-2026-10-16.json) retains exact
+source/input identities, failed attempts, coverage, IPC and resource receipts.
+Historical diagnostic helper hashes were not captured and remain explicitly
+unknown; the frozen hash is not assigned to them retrospectively.
+
+## Reproduction
+
+Build both pinned checkouts. Under the existing resource observer and a private
+Xvfb instance, use the committed helper for each runtime root in ABBA order:
+
+```sh
+node experiments/analysis-efficiency/drawio-electron-lifecycle.mjs \
+  --runtime-root /absolute/pinned-checkout \
+  --executable /absolute/electron-44.7.0/electron \
+  --application /absolute/drawio/resources/app.asar \
+  --profile-root /absolute/temporary-profiles --dismiss-error \
+  --selector '.geSidebar a.geItem:visible >> nth=0'
+```
+
+The helper returns failure on incomplete provider cleanup. This shared-service
+probe does not establish successful public CLI/MCP workflows. App images,
+extractions/profiles and full Result files are regenerable and excluded from Git.
+
+## Review follow-up: normalization before app decorators
+
+Fresh review of `f3bb9b9ed` found that translation inside a patched
+`removeListener` happened after an application's outer decorator had already
+seen the recording wrapper. Two native controls reproduced this with stable and
+replaced decorators (17 passed, two failed).
+
+`c8c494b5c` delegates the original Node traversal through a private forwarding
+receiver. It shares the real emitter's live state and translates owned `on`
+entries **before** invoking the current application removal method. App methods
+and getters receive the real emitter; read-only method properties remain valid.
+Native once entries pass unchanged. The public `removeListener`/`off` patches
+are removed. Five decorator variants pass: stable, replaced, read-only, getter
+and Proxy.
+
+An additional mutation case proved that reading a changed public `.listener`
+getter before delegation also changed deletion timing (22 passed, one failed).
+Final source `5a094a0df` retains canonical removal targets in the weak owner
+registry. Only unchanged data links are translated; changed getters run when
+Node performs removal, preserving the exception and state transition. All
+**23 cases** pass, including the original retention/fatal-error coverage.
+
+The same frozen draw.io verifier was reused. The follow-up ABBA attempt ran
+its first baseline, then the resource launcher refused the other three requests
+because 8 GiB plus its 4 GiB host reserve was unavailable. Those are **not
+executed**, with no performance measurements. The final source was separately
+admitted and completed dialog recovery and insertion with seven IPC events;
+overall cleanup still failed, and Xvfb teardown also returned an error. No new
+completed-task speedup or cold/warm pair is claimed.
+
+Final static checks passed: two uncached tasks, 135.173 s wall, 133.786166 family
+CPU s and 4,274,634,752 peak cgroup bytes, no OOM. The JSON record appends exact
+source pins, denial logs, final real-app/public cleanup diagnostics and checks
+under `review_followup`; the initial records were not overwritten.
+
+## Callback invocation and remaining raw-metadata limitation
+
+Source `514b73b78` invokes `handle` callbacks through captured `Reflect.apply`,
+preserving the receiver and actual arguments without reading an app-defined
+`.call` property. The added direct-call control and hook case pass; all **24
+IPC regressions** pass (3.661 s wall, 3.404 family CPU s, 318,291,968 peak cgroup
+bytes, no OOM). This is a Node boundary check, not a real Electron handle claim.
+
+An initial three-case experiment incorrectly assumed native EventEmitter avoided
+callable method-property reads. Its `on` and `once` controls themselves failed;
+they do not demonstrate hook regressions. The attempted intrinsic event-call
+change was reverted and those invalid cases removed. Both failed runs remain
+in `callable_followup`; no successful result is assigned to them.
+
+The same unchanged draw.io verifier at this source completes actual dialog
+recovery and shape insertion, with seven IPC events, SVG elements 0 → 2 and an
+unsaved-changes indicator. Overall provider cleanup still fails. Pipeline wall
+time is 12.610 s, family CPU 7.062834 s and peak cgroup memory 634,187,776 bytes;
+there is no paired performance or token claim. All recorded scopes were later
+independently inactive/dead, which does not establish provider cleanup.
+
+Fresh review also found a distinct remaining metadata case: changing a raw
+recording wrapper's writable `.listener` property can make an app decorator
+reject removal. A production-hook/native-Node probe reproduces this (plain:
+removed; hook: decorator throws and one listener remains). Exact reproduction
+and the ownership conflict are tracked in [#4513](https://github.com/morluto/rea/issues/4513).
+No affected real app has been identified. Removing the descriptor guard alone
+does not make native removal match the mutated wrapper; temporarily rewriting
+public app metadata would add further visible mutations. This limitation is
+explicit in the observation guide and is not represented as fixed by this PR.
+
+Current-source static checks also pass: two uncached tasks, 92.912 s wall,
+92.031383 family CPU s and 4,340,375,552 peak cgroup bytes, no OOM.
+
+## Native single/array dispatch follow-up
+
+Fresh review of `6fc2d2769` identified that the earlier native controls covered
+only one listener. Node 24.18.0 reads `.apply` during single-listener dispatch,
+but invokes each callback intrinsically during array dispatch. Native `once`
+uses `.call` for zero arguments and `.apply` otherwise. Unconditional `.apply`
+in the observation helper changed two of those paths: a multi-listener callback
+could throw before later callbacks ran, and zero-argument once read the wrong
+property. Four explicit native controls reproduce two failures (26 passed,
+two failed), rather than assuming all callable-property reads should disappear.
+
+Source `e8d7e8f20` keeps one observation boundary. An `on` recording wrapper
+delegates direct calls intrinsically and forwards native `.apply` calls through
+its own nonenumerable method. Node selects the route; the hook does not inspect
+or copy listener storage. `once` preserves its native zero/nonzero-argument
+invocation. All **28 cases** pass, including the prior callback identity,
+retention, reentrant-removal and fatal-error coverage. `handle` remains intrinsic.
+
+The unchanged real draw.io verifier again completes dialog recovery and shape
+insertion, with seven IPC events, SVG elements 0 → 2 and the unsaved indicator.
+Overall provider cleanup still fails; no deadline fires. Its 12.290 s pipeline
+run is a validation observation, not a paired performance comparison. Exact
+source hashes, failures, resource measurements and post-scope states are appended
+under `native_dispatch_followup`; all previous records remain unchanged.
+The separate raw metadata limitation [#4513](https://github.com/morluto/rea/issues/4513)
+remains open and is not represented as fixed.
+
+Final-source static checks pass: two uncached tasks, 171.430 s wall,
+169.139239 family CPU s and 4,091,392,000 peak cgroup bytes, no OOM.
+
+## Argument-list ownership follow-up
+
+Review of `23700fd2c` found two related representation errors. A raw callback's
+`.apply` accepts Arguments objects, other array-like objects, null or omitted
+argument lists; the recording helper assumed an Array. Native once also passes
+its actual Arguments object to a callback-defined `.apply`, whereas the hook
+passed a rest Array. Seven explicit native controls reproduce six failures
+(29 passed, six failed of 35).
+
+Source `a82d935ba` binds captured native Function apply to the method-forwarding
+function. JavaScript itself converts argument lists, treats null/undefined as
+empty and rejects invalid primitives before recording reads values. The
+array-like getter control is read exactly once. Once retains its actual
+Arguments object for invocation; recording alone takes an array slice. The
+captured slice helper is bound once, avoiding an extra helper-argument array
+on each invocation. No custom array-like parser or exception repair is added.
+
+All **35 cases** pass. The same frozen real draw.io verifier again completes
+dialog recovery and shape insertion with seven IPC events; no deadline fires,
+and overall provider cleanup still fails. Exact source identities, both failed
+boundaries, intermediate/final tests, resource costs and post-scope states are
+appended under `argument_list_followup`; previous records remain unchanged.
+
+Current-source static checks pass: two uncached tasks, 122.454 s wall,
+121.287057 family CPU s and 4,185,915,392 peak cgroup bytes, no OOM.
+The unchanged ASAR digest was checked again after the real-app trial.
+
+## Owned metadata and successful-Evidence verifier follow-up
+
+Fresh review of `41a513d99` found that `on` wrapper metadata used strict
+assignment. Native on does not write such metadata, so inherited Function or
+Object prototype setters/read-only fields could prevent registration only under
+capture. Four native controls fail before `5dcf79f29` (35 passed, four failed).
+The recording wrapper now defines its own data property directly; native once
+assignment behavior is retained. All **39 cases** pass.
+
+The verifier also incorrectly treated a successful Evidence envelope as a raw
+capture. Real cleanup failures had exercised only the separate partial path.
+`4a9a01f7a` reads successful `value.normalized_result` and preserves failed
+`error.partialObservation.capture`. The new
+`experiments/analysis-efficiency/drawio-electron-lifecycle-oracles.py` exercises
+the actual verifier with controlled success, partial cleanup, action failure,
+insertion failure and absent capture. The old verifier rejects valid successful
+Evidence before producing a summary; all five corrected controls pass.
+**These are controlled reply/exit checks, not real-provider evidence.**
+
+The corrected verifier was separately frozen before a real unchanged draw.io
+trial. Actual dialog recovery and shape insertion again complete with seven IPC
+events, no deadline and failed overall provider cleanup (pipeline 12.777 s).
+Success with real provider cleanup remains unverified. Earlier trials retain
+their earlier verifier hashes; the corrected hash is not assigned to them.
+Exact source pins, failed controls, resource costs and post-scope states are
+appended under `owned_metadata_and_verifier_followup` without replacing history.
+
+Final-source static checks pass: two uncached tasks, 99.992 s wall,
+98.956939 family CPU s and 4,237,795,328 peak cgroup bytes, no OOM.
+
+## Species-free recording and snapshot ownership
+
+Fresh review of `e2cf2d89b` found that slicing a rest Array invokes application
+`Array[Symbol.species]` before dispatch. The first control reproduced failed on
+dispatch (40 passed, one failed); once dispatch already used Arguments.
+Extending the check to retrieve the retained snapshot while the throwing getter
+remains installed exposed the same representation problem in snapshot maps
+(39 passed, two failed).
+
+Source `3141ac3f4` records from actual invocation frames while preserving native
+callback argument-list types: the method-based on path still passes an Array,
+and once passes Arguments. Group validation uses the existing recording loops
+without a filtered intermediate Array. Captured `Array.from` produces snapshots
+without species lookup, reading dropped-counter Maps directly rather than
+spreading them into another Array first. The initial **41 cases** pass, including both
+live snapshots under the throwing getter with zero getter reads.
+
+The frozen-source real unchanged draw.io operation again completes recovery and
+insertion with seven IPC events, no deadline and failed overall cleanup
+(pipeline 12.779 s). This does not establish that draw.io customizes species.
+The corrected verifier and its five previously passing controlled oracles are
+byte-identical to `4a9a01f7a`, so those unchanged oracle sources were reused.
+Exact hashes, failures, resource receipts and scope states are appended under
+`array_species_followup`; earlier records remain unchanged. There is no new
+completed-task performance or token/context claim.
+
+The native multiple-listener route was then included in the same live-species
+control: all **42 cases** pass. Only test coverage expanded; production hook
+and verifier bytes remain identical to `3141ac3f4`. Exact validation identities
+and the additional result are recorded under `all_native_dispatch_paths`.
+
+A fresh-profile real negative control omits `--selector` while retaining dialog
+recovery and the same 500 ms wait. SVG elements remain **0 → 0** and unsaved
+changes remain false; insertion gives **0 → 2** and unsaved true. This supports
+the operation oracle rather than attributing startup rendering to the click.
+The control also returns seven IPC events and failed provider cleanup. These
+are different tasks, not a performance pair or a model-cell-count proof.
+
+Final 42-case source validation includes two uncached static tasks passing in
+94.234 s wall, 93.308800 family CPU s and 4,406,538,240 peak cgroup bytes,
+with no OOM. These are verification costs, not an application speedup.
+
+## Opaque apply inputs and iterator-free snapshots
+
+Fresh review of `84d9cf5db` found two producing-boundary regressions: native
+array-like conversion replaced the argument-list object before a custom
+listener `.apply` received it, and `Array.from` snapshots consulted application
+iterators on retained arrays/Maps. Four exact-input native controls and two
+snapshot controls fail before correction (42 passed, six failed of 48).
+
+Source `e442ca27f` forwards custom `.apply` the original receiver and method
+arguments without interpreting its opaque list. Custom apply may transform
+arguments or skip callback execution, so the hook emits a bounded
+`ipc-observation-gap` timeline record with the known registration channel. It
+does not fabricate a main-event invocation, argument shapes or callback result.
+The shared result projection retains explicit uncertainty and counts dropped
+gaps through existing retention. The canonical timeline enum adds that kind;
+the captured-IPC subset does not. Native apply still performs its own conversion
+before an actual callback frame is observed.
+
+Snapshots now copy arrays through private null-prototype indexed views and
+counters through captured native Map traversal. Neither retained buffers nor
+counter Maps are exposed to application iterators; returned records and shape
+arrays remain independent copies. No cache, tool or normal-dispatch metadata
+is added. The raw-wrapper metadata limitation in #4513 remains unfixed.
+
+The focused hook/projection/actions gate passes **68 cases** (48 + 4 + 16).
+The separate MCP/schema gate passes **23 cases**: an actual SDK client receives
+the gap alongside ordinary IPC Evidence, and Ajv2020 validates the advertised
+converted output; all canonical tool schemas also pass their existing checks.
+These tests use controlled providers and establish no real-provider success.
+The verifier and its five controlled exit/summary oracles are hash-identical to
+the earlier passing source and are reused without another redundant run.
+
+## Unrelated CI baseline failure
+
+CI run `38935598884` tested synthetic merge `eedae92d406015895a6d0eced5035da1b9ead07a`
+(head `84d9cf5db`, base `9d940c2f2`). Two firmware cleanup tests failed; another
+shard was cancelled by fail-fast. A fresh, unmodified detached checkout of that
+exact base reproduces the same failures: **33 passed, two failed** in
+`tests/boundary/firmware/firmwareIntegration.test.ts`. Evidence is posted on
+[the PR](https://github.com/morluto/rea/pull/4389#issuecomment-6221054273) and
+[existing #4475](https://github.com/morluto/rea/issues/4475#issuecomment-6221054775).
+This establishes that these failures predate the Electron changes; it does not
+resolve whether the firmware producer or its expectations need correction. No
+firmware code or assertions are changed here, and required CI is not bypassed.
+
+The first final-source real request fails before application launch because the
+previous `/tmp` runtime is absent. It is retained as an input-resolution failure,
+not a provider measurement. The cached Electron 44.7.0 archive is verified against
+the official release SHASUMS256 and extracted into a new owned task directory;
+its executable/archive digests are pinned before the next request. No target
+source, vendor fuse or scenario success requirement is changed.
+
+The recovered-runtime real operation completes all three declared actions:
+SVG elements **0 → 2**, unsaved changes true, seven IPC events, no deadline.
+Overall provider cleanup still fails. Current-source static validation passes
+two uncached tasks in **94.646 s wall, 93.878644 family CPU s and 4,300,570,624
+peak cgroup bytes**, no OOM. The initial static attempt's test-only SDK/Ajv type
+error is retained; parsing that boundary fixes it, and 12 affected client and
+projection cases pass again. `opaque_apply_and_iterator_followup` preserves all
+source pins, failures, resource receipts and independently checked scope states
+without replacing earlier measurements. Draw.io does not establish that real
+applications exercise the synthetic custom-apply/iterator cases.
+
+The final documentation gate also passes six tasks and five README consistency
+cases. Source and unchanged ASAR hashes are checked again after validation.
+
+## Borrowed apply receivers
+
+Fresh review of `7541a900c` supplied the borrowed custom-method case
+`raw.apply.call(g, emitter, list)`: the plain emitter runs `g`, while the hook
+hard-coded its registered callback as the method receiver. The same hard-coded
+receiver also affected borrowed native apply. Both native differential controls
+fail before correction (48 passed, two failed of 50).
+
+Source `da04465fe` maps only the hook wrapper itself to the original listener
+when forwarding custom apply; other method receivers pass unchanged. Native
+apply uses its actual receiver, preserving both ordinary wrapper recording and
+borrowed-call dispatch. The hook does not fabricate a registered callback
+invocation when another callable is selected. The method-forwarding boundary is
+corrected directly; no new helper, state, tool or schema is added. All **70**
+hook/projection/actions cases pass (50 + 4 + 16). Shared schema/client, projection
+and verifier/oracle sources are byte-identical to the prior passing versions,
+so their checks are reused by verified hash.
+
+CI run `38943919946` is confirmed by the successful build checkout log and Git
+parents to use merge `98c14dfc01fe4698a50eedc8b1cd1ac9cd03267d`
+(head `7541a900c`, main `4838f4449`). Its fifth shard fails the same two firmware
+cleanup tests as the unmodified `9d940c2f2` base control. The relevant firmware
+source/test and package paths have no changes between these main revisions.
+The REST PR `base.sha` remains stale at `2c7583599`; it is not used as the CI
+identity. No firmware code/assertion or required-check bypass is included.
+
+The frozen-source unchanged draw.io operation completes recovery/insertion
+again with seven IPC events, SVG **0 → 2**, unsaved changes true and failed
+overall provider cleanup. Pipeline: **12.038 s wall, 6.662295 family CPU s,
+598,835,200 peak cgroup bytes**. This remains a partial workflow, not a speedup
+claim. Final static checks pass two uncached tasks in **108.067 s wall,
+106.996233 family CPU s and 4,430,647,296 peak cgroup bytes**, no OOM.
+All prior measurements remain unchanged under `borrowed_apply_followup`.
+
+The final documentation gate also passes six tasks and five README consistency
+cases. Current source digests are checked again after validation.
+
+## Listener-owner intrinsic lifetime
+
+Fresh review of `f5b489c1b` found that late application replacement of
+`Object.defineProperty` prevents the hook's new wrapper properties from being
+created, while a plain native emitter still registers/invokes its callbacks.
+Inspection of this same new registration/removal owner found its other late
+property/constructor lookups. Seven independent native controls replace
+`Object.defineProperty`, `Object.getOwnPropertyDescriptor`, `Object.create`,
+`Reflect.get`, `Reflect.set`, global `Set` or global `Proxy`; each fails before
+correction (50 passed, seven failed of 57). The controls include both on/once
+execution and complete removal, with globals restored after the scenario.
+
+Source `a9c5611d0` captures the owner's descriptor/property operations and private
+constructors before application startup. The private receiver uses a direct
+null-prototype object literal instead of looking up Object.create. All **77**
+hook/projection/actions cases pass (57 + 4 + 16). Application-owned callback
+methods and actual receivers retain their existing semantics. No tool, schema,
+state, target authority or general-purpose hardening layer is introduced; this
+is not complete JavaScript introspection equivalence. Unchanged schema/client,
+projection and verifier/oracle checks are reused by verified source hashes.
+
+The preceding CI run `38946503183` tests confirmed merge
+`fcd7a9d92a2e64d6eb96d4fabfed7fc7f44b0d45` (head `f5b489c1b`, main `4838f4449`).
+Its 36 jobs finish with 29 successes, the same two firmware failures causing
+three failed jobs including summaries, and four fail-fast cancellations. The
+fifth-shard log again names the two cases reproduced on untouched main. No
+firmware code/assertions or required checks are altered.
+
+Frozen-source real unchanged draw.io actions complete again with seven IPC
+events, SVG **0 → 2**, unsaved changes true, no deadline and failed overall
+provider cleanup. Pipeline wall is **11.429 s**. Observed payload-exit cgroup
+counters are 6.441029 CPU s and 550,363,136 peak bytes, but the observer still
+sees one additional scope descendant: **family resource observation is
+unverified**, not a complete-family performance measurement. The scope is later
+inactive/dead after external recovery; this does not verify provider cleanup.
+No identity or cleanup cause is inferred from the remaining PID.
+
+Final static checks pass two uncached tasks in **90.980 s wall, 90.119351 family
+CPU s and 4,338,749,440 peak cgroup bytes**, no OOM. Source identities, all seven
+failures and resource limitations are appended under `listener_intrinsics_followup`
+without replacing any previous measurements.
+
+The final docs gate passes six tasks and five README consistency cases; source
+digests are checked again after validation.
+
+## Private collection method lifetime
+
+Fresh review of `e6c373d0` found that replacing `WeakMap.prototype.has` after
+hook initialization still intercepts its private wrapper registry. Inspecting
+the same owner found analogous get/set and visited-Set has/add lookups. All five
+independent native controls fail before correction (57 passed, five failed of
+62); plain EventEmitter registration, on/once calls and complete removal succeed.
+
+Source `774ed6aa6` binds these private WeakMap/Set methods before application
+startup and reuses captured Set membership for event-family classification.
+One initialization-only binding helper replaces duplicated binding construction
+for existing Map traversal/argument slicing too. It adds no helper argument
+arrays per invocation, cache, schema, tool or target authority. Application-owned
+callback methods/receivers remain dynamic. All **82** hook/projection/actions
+cases pass (62 + 4 + 16). The previous seven global-binding controls also remain
+green, and unchanged schema/client/projection/verifier/oracle checks are reused
+by verified source hashes. Arbitrary introspection and #4513 remain unsupported.
+
+Frozen-source unchanged draw.io actions complete again with seven IPC events,
+SVG **0 → 2**, unsaved changes true and failed overall provider cleanup. Pipeline
+wall **11.238 s**; observed payload-exit cgroup CPU **6.285321 s**, peak
+**556,285,952 bytes**. Another scope descendant remains at payload exit, so complete-family resource observation is unverified. Later external scope teardown does not prove provider cleanup.
+
+Final static checks pass two uncached tasks in **92.999 s wall, 92.227652 family
+CPU s and 4,371,951,616 peak cgroup bytes**, no OOM. Preceding CI38949129899 checks
+confirmed e6c3 + main4838, repeats the same two firmware failures and finishes
+31 successful /3 failed jobs including summaries /2 fail-fast cancellations.
+Sources, failures and resource limitations are appended under
+`private_collection_methods_followup`; prior fields remain unchanged.
+
+The final docs gate passes six tasks and five README consistency cases; source
+digests are verified again afterward.
+
+## Unknown listener-chain ownership
+
+Fresh review of `0b4f2e81` found that the bounded Boolean chain test treats a
+still-unexamined function as fresh when 17 app decorators hide an owned once
+wrapper. Two emits then produce three invocation records for one actual once
+callback. The same unknown-as-fresh error affects accessor/Proxy links. Four
+native controls fail before correction (63 passed, four failed of 67); the
+16-decorator boundary already passes. A deep ordinary on control confirms
+missing ownership cannot justify fabricated captured IPC either.
+
+Source `ef46b8f0b` classifies metadata as owned, unowned or unknown. Bounded-walk
+exhaustion, accessor links and Proxies preserve native registration without
+adding another recording wrapper. Successful unknown registrations retain a
+bounded `listener-chain` gap; this is not proof of IPC delivery. An existing
+inner wrapper may still report its actual once invocation. Shared native
+data-descriptor parsing preserves accessor uncertainty at recognition/removal
+and avoids inherited descriptor-value interpretation. The superseded Boolean
+classification is removed.
+
+The shared projection explains both gap boundaries and retention/coverage, and
+an actual MCP SDK client receives custom-apply and listener-chain gaps alongside
+ordinary IPC Evidence, validated by its converted advertised schema. All **96**
+hook/projection/actions/MCP cases pass (67 + 5 + 16 + 8). A test-only lint length
+failure is corrected by generating repeated fixture rows from one table without
+relaxing rules; all **13** affected client/projection cases pass again. The
+canonical schema and unchanged verifier/five controlled oracle sources retain
+their earlier passing checks by verified hashes; the changed projection/client
+are freshly tested rather than claimed unchanged.
+
+Prior CI run `38951509761` uses confirmed merge
+`fa090a6bde3a5dadeb71066824477292520fb43b` (0b4f + mainf31b231a). All **36 jobs
+succeed**. The earlier unrelated firmware failures do not recur in this
+combination; their cause is not inferred or claimed fixed here. Current-source
+CI/review remain required. No firmware code/assertions were modified.
+
+Frozen-source unchanged draw.io recovery/insertion again completes with seven
+IPC events, SVG **0 → 2**, unsaved true, no deadline and failed overall provider
+cleanup. Pipeline wall **11.163 s**; observed payload-exit cgroup CPU **6.203177 s**,
+peak **547,418,112 bytes**. An extra scope descendant leaves complete-family
+resource observation unverified; later inactive/dead scope after external
+recovery does not establish provider cleanup.
+
+Final static checks pass two uncached tasks in **88.383 s wall, 87.726306 family
+CPU s and 4,399,632,384 peak cgroup bytes**, no OOM. All source identities, failed
+controls, corrected fixture-only lint failure and resource caveats are appended
+under `chain_ownership_followup`; historical fields are unchanged.
+
+Final docs validation passes six tasks and five README consistency cases;
+current source digests are verified again afterward.
+
+## Inherited listener-link coverage
+
+Fresh review of `ae2cd8d4` found that a missing own descriptor is not absence:
+an app decorator can inherit its data link to an owned once wrapper. Native
+removal follows that link and removes the decorator; the hook hid it under
+another recorder, left a listener installed and produced three invocation
+records for one callback. Five native inherited-link cases fail before correction
+(68 passed, five failed of 73): data/getter/Proxy prototypes and prototype
+depths16/17. A late Object.getPrototypeOf replacement control already passes.
+
+Source `e22ce9aaf` completes bounded native prototype lookup at the descriptor
+owner, capturing getPrototypeOf before startup. Data links retain their actual
+source value. A setter-only property has a known undefined read that shadows
+ancestors; a getter, Proxy or incomplete walk remains unknown. Missing metadata becomes absent only after the prototype chain ends; found
+properties retain native read/shadowing semantics. Registration and removal consume
+the same parsed descriptor, and redundant outer Proxy interpretation is removed.
+Neither existing resource bound is raised. All **102** hook/projection/actions/
+MCP cases pass (73 + 5 + 16 + 8). Projection/client are freshly tested unchanged
+sources; canonical schema and verifier/oracles retain prior checks by hash.

+# Native Electron once dispatch — 2026-10-16
+
+#4593 was reported by review of #4562, but its source was already in main from
+#4389. The initial report was explicitly source-only; subsequent paired controls
+confirmed the bug. This change delegates `once` creation, firing and callable
+selection to the actual runtime and observes only established callback entry.
+CLI and MCP continue to share the same hook, event model, projection and retained
+Evidence. No new tool, schema, execution authority or analysis cache is introduced.
+
+## Paired native controls
+
+The baseline is `709b5cbdc15aa757f89c38ecd12e5a47710747a6`. Final source is
+`4ebd0f60e860daa57a7033c6e77ea7f5f4b8ac97`, including the two review-gap fixes below. Earlier source cohort
+`c0b52b5408fa97013798e6ecee885ccac08e7356` contains the fix; the final cleanup
+commit is `e60c4a1098321ed2a7f564ae35909a31d707694f`, which removes the obsolete fifth helper argument and
+unreachable copied call/apply dispatch branches after inspecting every caller.
+The pre-review gap-owner follow-up is `7f05f476c52498adba41d943ead1a86e7216ca76`. The adjacent JSON preserves
+source hashes and separate measurement cohorts, including the initial 93-row prefix.
+The final review JSONL contains 117 paired rows (39 inputs × 3 runtimes). The
+earlier 96-row JSONL remains unchanged, including its initial 93-row prefix. Both
+comparisons have identical native
+control facts in each before/after pair. Regenerable binaries, apps, profiles
+and multi-MB raw captures are excluded from Git.

+
+The original 21-case reproduction found 0/9/9 differences respectively. The
+pre-review 32-case cohort found 1/13/13. The final 39-case suite adds readonly
+callback methods, emitter method invariants, native metadata writes, failure
+recovery and non-callable callback methods. The extra pinned-runtime difference is registration
+metadata ordering. On the newer runtimes, opaque callback methods can suppress
+callbacks under the old hook although native dispatch executes them. The pinned
+runtime also catches false invocation records when an opaque method legitimately
+skips the callback. The added regression fails on the baseline for that false fact.
+
+These are **controlled producer cases with a minimal Electron module**, including
+the actual embedded Node binary, not a real GUI application's natural callback
+loss. Native traces, receiver checks, failures and remaining listeners are compared
+exactly. Expected property reads are derived from each runtime rather than copied
+from one Node implementation. The custom-apply guard still checks its original
+Arguments representation when the runtime actually invokes that method.
+
+## Ownership and uncertainty
+
+Native once wrappers keep their public callback identity and descriptor attributes.
+The registration receiver forwards methods/getters to the original emitter and
+supports readonly method descriptors. A private callable receives an actual
+Arguments frame, avoiding application Array species/iterators when recording.
+Metadata recognition and admission share one bounded descriptor lookup.
+
+An application-selected opaque call/apply can bypass observation; a bounded
+`custom-call`/`custom-apply` gap replaces invented invocation facts. Opaque native
+metadata writes or registration lookups keep the exact original callback/native
+operation and emit `once-metadata` gaps. The temporary unobserved scope is restored
+even if registration throws. The 39-case suite checks this recovery, including a native alias that bypasses
+patched `on`; the once owner retains the observation gap for that path. #4513 raw
+recording-wrapper mutation remains explicitly unfixed.
+
+Review found two missing failure facts: a decorator can register through an
+unhooked alias and then throw, and a runtime can read a non-callable call/apply
+property before dispatch fails. Both new regressions fail on the pre-review
+source. The once owner now finalizes its missing gap in `finally`, after restoring
+the scope; the callable metadata owner records a failed gap while preserving the
+exact non-callable value. Error identity and native callback behavior are retained.
+
+Two short-lived proxies are used for an observable once registration. Metadata
+remains weakly retained, and existing event/serialization budgets remain in force.
+The added registration cost was not isolated; no speed or token improvement is
+claimed. The saved producer comparison is a correctness experiment, not a whole
+application performance benchmark. Its runner reports differences instead of
+exiting unsuccessfully for an expected bad baseline; the regression tests assert
+that fixed behavior matches native behavior and observation claims are truthful.
+
+## Real application verification
+
+Unchanged Joplin Desktop 3.7.21 ASAR and explicit generic Electron 44.7.0 run the
+shipped welcome note/1075×666 PNG → actual resource context menu → app bridge →
+blocked reveal workflow. The image stays visible, page errors remain empty,
+reveal events increase 0→1, and the shared retained capture contains the exact
+event. Both staged hook files are hashed against the selected source before launch.
+No synthetic application IPC channels or replacement app callbacks are added.
+
+The argv shim is an explicit test adapter for the still-failing standard startup
+#2974. **Overall provider cleanup remains failed (#4282)** and the verifier exits
+nonzero. External scope teardown is not provider cleanup. The first frozen real
+pipeline takes 17.680 s; observed payload-exit CPU 16.272793 s and peak 1,395,253,248 B
+have an extra descendant, so complete-family observation is **unverified**. The
+cleanup cohort is recorded separately. The pre-review 32-case source repeats the real
+operation successfully, but overall cleanup still fails: 18.074 s pipeline, observed
+CPU 17.011774 s / peak 1,422,839,808 B; complete-family measurement remains unverified. No completed public CLI/MCP workflow,
+real Windows/macOS run, natural app callback-loss reproduction or full check:pr
+is claimed.
+
+The final review source repeats the same real operation: 18.353 s pipeline,
+observed CPU 17.098599 s / peak 1,387,556,864 B; complete-family measurement remains
+unverified and overall provider cleanup fails. An earlier trial failed to initialize
+the display because the provider environment omits XAUTHORITY. That launch is
+preserved separately; the fresh final trial uses local Xvfb with `-nolisten tcp -ac`,
+not a production provider change.
+
+Frozen local validation: 75 hook cases on both Node versions; 5 projection + 8 MCP
+cases on the unchanged shared contracts; static checks pass (final 118.946 s wall / 117.752622 s CPU / 4,282,826,752 B
+cgroup peak, verified payload-exit family observation). The pinned final run uses
+`test:focused`; an attempted `test:local` invocation was rejected before tests ran
+and is recorded as not executed. See JSON for exact
+commands/cohorts, failed candidate attempts, source pins and measured resources.
+Failures include the Array-species frame, readonly receiver invariants, metadata
+setter identity, on-getter ordering, a lint/interoperability correction and helper
+preparation failures. They are not relabeled as results from the final source.
+
+All heavy work runs serially with CPU 10/quota 1, 8 GiB hard/6 GiB early/no swap/192 tasks.
+Counters are captured at payload exit with the observer alive, not final whole-scope
+counters; cgroup peak includes file cache. Each final Joplin run has a new private
+configuration mount. Filesystem/runtime/build caches are warm; cold-system and
+warm-repeat costs are unmeasured. Agent/billed tokens and public reply/context
+costs are unmeasured. The broad internal error capture size is not an agent-token
+measurement. All owned scopes are checked inactive/dead independently.
+
+## Reproduce the producer comparison
+
+Use the pinned project toolchain and explicitly provided alternate runtimes.
+The alternate Node 24.21 archive is checked against [official checksums](https://nodejs.org/download/release/v24.21.0/SHASUMS256.txt);
+its archive/binary hashes are recorded. No global toolchain is upgraded.
+
+```sh
+python3 experiments/analysis-efficiency/electron-once-runtimes.py \
+  --hook-root /absolute/checkout-to-measure \
+  --node /absolute/pinned-node \
+  --node /absolute/node24.21 \
+  --electron /absolute/generic-electron44.7 \
+  --output /absolute/owned-output
+```
+
+Run this under the recorded resource wrapper. For a baseline comparison, use a
+clean checkout of 709b5cbd as hook-root while keeping the same current oracle/runner.
+The runner retains full JSON and prints a compact summary. The real Joplin recipe
+is in [the shell verifier record](electron-shell-sync-2026-10-16.md); select the
+current runtime-root. That workflow must remain nonzero while cleanup fails.

+# Electron synchronous shell boundary verification — 2026-10-16
+
+Fix #4393 reuses Nitin13-git's existing PR #4562. The boundary owns a fixed
+method/return table: existing asynchronous blocks still reject, while
+`showItemInFolder` returns `undefined` and `writeShortcutLink` returns `false`.
+Both new blocks use the existing shape-only event recorder, shared by CLI/MCP.
+No tool, schema, capture authority, analysis cache or launch behavior is added.
+
+## Source and controlled regression
+
+The fresh main base is `f26973a52918a938631e90fdc9116f7b85a62a52`;
+implementation integration is `0386b60fb` and frozen verifier source is
+`3f231735c3fbc28918590ddc61461871c8a2aa4d`.
+The adjacent JSON records frozen final script/runtime/input hashes and all attempts;
+unpinned exploratory helper revisions are explicitly identified.
+Original contributor attribution remains in Git ancestry.
+
+Using the candidate test with the base boundary produces **73 passes / 1 failure**:
+the fake native shortcut implementation executes and returns true. With the
+candidate boundary, **87 cases pass** (74 staged-hook, 5 projection, 8 MCP).
+These test native dispatch suppression, synchronous results, shape-only
+retention and the shared event schema. The fake Electron cases and controlled
+MCP provider do not prove a real Windows shell implementation was exercised.
+`npm run check:fast` passes both uncached tasks. Build-cache differences and
+different case counts make the red/green timings unsuitable as a speed comparison.
+
+## Real Joplin workflow and limits
+
+Inputs: unchanged Joplin Desktop **3.7.21** ASAR (233,575,014 bytes), and the
+explicit generic Electron **44.7.0** runtime. Acquisition/checksum references
+are in `javascript-native-handoff-identity-2026-10-15.json` and
+`electron-cancellation-2026-10-16.json`; this is not vendor-executable compatibility.
+No executable fuse is changed. Large downloadable inputs and generated profiles
+are not committed or retained as an experiment bundle.
+
+The verifier opens Joplin's shipped **1. Welcome to Joplin!** note and real PNG
+attachment. It selects Joplin's actual editor layout and resource context-menu
+callbacks; Joplin's existing bridge calls the real patched shell method. The
+native popup presentation is captured for automation; its application callbacks
+are not replaced. Before any app actions, the verifier requires the active hook.
+It requires zero earlier reveal events, one new blocked shape-only reveal event,
+a still-rendered attachment and an identical event in the shared retained capture.
+
+**Standard launch remains unsuccessful.** The earlier standard probe reports
+`Unknown flag: -r` in Joplin's start-flag parser; the frozen standard verifier
+times out waiting for the application search input. This is relevant to #2974,
+not fixed here. A discarded NODE_OPTIONS experiment was invalid: Playwright
+removes that variable, so no hook was installed. Those attempts are never used
+as interception or performance evidence.
+
+The explicit `--argv-shim-transport` test adapter loads the provider's staged
+canonical hook and removes only its own exact `-r`/shim pair from app argv before
+Joplin starts. It does not modify the ASAR or production provider. Its successful
+operation phase is not a successful standard public CLI/MCP workflow. Provider
+cleanup still fails (#4282); the verifier exits nonzero, preserving the distinction.
+External owned-scope teardown does not establish provider cleanup.
+
+The first valid shim probe reaches one blocked reveal, visible 1075×666 PNG,
+no page errors and retained capture evidence. The final frozen rerun additionally
+checks event causality and exact capture equality. Detailed measured results and
+whole-family observation status are in the JSON. The final controlled pipeline
+takes16.989s wall /16.055812 family CPU s /1,376,382,976 peak cgroup bytes
+with verified payload-exit observation; the overall workflow still fails cleanup. Each final trial has a new
+private config mount; earlier exploratory shared-config trials are not independent
+cold runs. Filesystem/runtime/build caches are warm; no cold-system or warm-repeat
+speedup is claimed. Agent/billed tokens are unmeasured; there is no token benefit claim.
+
+## Reproduction
+
+Use the pinned Node/npm toolchain. Install dependencies and build with
+`npm ci` and `npm run build:cached`. Create an owned writable packet directory
+with `tmp`, `profiles`, and `config/joplin-desktop`. On Linux, bind that private
+config over the actual user config directory in a disposable `bwrap` mount
+namespace (do not change HOME), keep the application resources read-only and
+run under Xvfb. Set TMPDIR to the owned writable packet `tmp` directory. Run:
+
+```sh
+node experiments/analysis-efficiency/joplin-shell-boundary.mjs \
+  --runtime-root /absolute/rea-checkout \
+  --executable /absolute/generic-electron \
+  --application /absolute/Joplin/resources/app.asar \

+  --argv-shim-transport
+```
+
+Omit the last flag for the failing standard launch. Run heavy work serially under
+`resource-run.py --memory-gib 8 --observe-payload-exit`, one CPU, no swap, the
+6 GiB early-stop margin and 192-task ceiling. CPU/peak memory receipts are at
+payload exit with the observer alive; memory includes file cache, not just RSS.
+Unverified complete-family observations are explicitly marked. No Windows host,
+macOS host, vendor packaged runtime or full `check:pr` was executed here.

+# Interrupted application processing: applicability and Evidence
+
+Tracks #3948 under #4027. Measured baseline:
+`c7f6b8bad1a34d5efb30ff2a017672dea1fcdabb`.
+
+The question is which processing phases remain unavailable after a source
+interruption, while keeping native inventory and already collected facts.
+Native identity and provider linkage must stay independent of application-wide
+partial coverage. This is static artifact analysis; no target application or
+native provider runs.
+
+## Observed failure and correction
+
+The interruption producer previously attached one generic failure to every
+remaining relevant file. Graph projection interpreted it as JavaScript AST work.
+Real Joplin reproduced an `analyze-javascript-source` / `ast-static-analysis`
+unavailable scope on keytar's native binary and on unvisited package, HTML and
+source-map files. Public CLI/MCP controls reproduced the same applicability
+problem. Deterministic cancellation before native metadata additionally produced
+a phantom JavaScript semantic module for the binary.
+
+The producer now records the applicable operation/authority and whether the
+phase was entered. `analysis_status: interrupted` includes worker startup and
+does not imply parsing completed; `not-started` identifies unvisited phases.
+Native add-ons need no post-inventory source-processing phase, so neither interrupted
+nor caller-excluded native files acquire AST scopes or semantic modules.
+Actual JavaScript failures, structured-file unknowns, caller selection and byte
+identity remain available. The graph consumes these produced facts.
+
+The AST-only unavailable Evidence helper is replaced by an explicitly typed
+static helper. Normal package/JSON/map gaps also retain their artifact-byte
+authority. Per-file progress uses the same applicability owner: JavaScript keeps
+its source phase, and metadata uses `process_javascript_artifact_metadata`.
+Remaining parsers do not run after interruption. Failure sharing is limited to
+five applicable phases during one interruption; no persistent cache is added.
+
+A second review found the alternate full-analysis semantic builder still
+created modules for every excluded file kind. An actual filesystem-producer
+regression on revision `323fae8cbf3e36677bcb7b22ba31fa1a7e3c5cd4` reproduced
+phantom native/JSON/HTML/package/source-map modules, while selected and excluded
+JavaScript were positive controls. Semantic applicability now belongs to the
+shared `recordUnavailableFile` projection entry point, before retaining limits,
+nodes, roots or unknowns. Three duplicate caller checks are removed. Both full
+and incremental construction use this boundary; actual excluded JavaScript
+continues to carry source-bound unknowns and partial semantic coverage.
+
+## Real input and reproduction

+```
+
+Omit `--require-safe` on the baseline timeout run to record its incorrect
+applicability. Its diagnostic exit 0 is not a passing analyst task. A supported
+1 ms deadline includes worker startup; the verifier requires a typed timeout
+and retained partial reference for that cohort. Each structured path supplies an
+independent expected operation and phase-entry status; the safety oracle matches
+all gaps exactly, including unavailable state and unknown confidence. Missing or
+conflicting expectations do not pass.
+
+The native path is explicitly selected. An earlier structured-only run excluded
+it and therefore did not reproduce the native interruption. Input selections
+and that preliminary result remain recorded. Both final cohorts preserve
+partial coverage for unselected/unavailable scopes.
+
+The supplied native Evidence is simulated solely to check exact subject linkage.
+The verifier checks physical companion bytes and the exported parent's root
+digest, validates public CLI/MCP native-trace parity, and reports only after
+owned transport/command/private-file cleanup. Applications and large Evidence
+are regenerable and are not archived.
+
+## Two distinct task projections
+
+The **timeout task** includes the expected typed-timeout preparation, one inline
+native trace and three inline structured-path traces. It checks that native has
+no AST failure and that each unvisited structured phase remains unavailable with
+the appropriate artifact-byte authority and `not-started` status.
+
+The **default-deadline control** models the summary plus one inline native trace.
+Its named structured paths are additionally validated from the already exported
+complete parent, explicitly labelled `exported-parent-validation`. Those checks
+are diagnostic overhead outside the modeled native-task tokens and inside total
+verifier resources. They are not presented as inline metadata answers.
+
+A control that also requested the complete outgoing `package.json` feature trace
+hit stdio admission twice: at least 10,587,373 bytes against a 10,484,736-byte
+result budget, with identical retained parent/trace identities. It is not a
+completed equivalent task or an efficiency baseline. [#4190](https://github.com/morluto/rea/issues/4190)
+records the separate need for exact retained metadata/native fact views. Complete
+export remains available. Do not compare costs across these different tasks.

+
+The full-catalog alternatives and per-query samples are preserved in JSON.
+Native content identity, observed byte provenance, source selection and handoff
+provider Evidence remain equal. Corrected global provenance changes derived
+parent/trace identities; null partial-Evidence subjects remain null. Both final
+runs have exact CLI/MCP native-trace parity and match the earlier post-fix
+controls in every recorded non-timing field.
+
+The whole verifier includes input hashing, analysis, three native trace rounds,
+applicable structured queries, export, CLI parity and tokenization. Every heavy
+run uses the preserved [resource observer](https://github.com/morluto/rea/blob/b3bdabab694af1f9801eff7caf75001b92314a58/experiments/analysis-efficiency/resource-run.py):
+one CPU, 8 GiB hard cap, 6 GiB early stop and no swap. Cgroup peaks include charged
+file cache, not summed RSS. Counters are observed at payload exit while the
+observer remains alive, not final whole-scope counters. Completed runs verify
+owned cleanup and report no OOM.
+
+Each MCP process is fresh, but input hashing warms its file cache. Build/OS caches
+and shared-host scheduling are uncontrolled. First and repeated retained-query
+wall samples remain separate; isolated query CPU/memory are unmeasured. An
+earlier fixed timeout took 150.173 s wall / 119.468013 s CPU; its exact unchanged
+runtime repeat took 58.827 s / 58.482996 s, with identical non-timing facts,
+Evidence and BPE. Both receipts are retained. The final default control also took 186.085 s wall / 142.371100 s CPU; its
+unchanged-runtime repeat took 62.651 s / 62.240964 s with identical non-timing
+results. The slow final row remains reported. Attribution remains unresolved;
+these runs establish no speedup or performance-equivalence bound.
+
+The stricter post-review verifier reruns also passed without changing production
+code: timeout 162.645 s wall / 125.876114 s CPU / 2,809,643,008 B peak; default
+control 61.367 s / 60.970077 s / 2,526,949,376 B. Both preserve the original final
+analytical fields, identities, coverage and BPE exactly; only timings and the new
+explicit oracle-input field differ. These additional receipts do not replace the
+slower rows above.
+
+After centralizing semantic applicability, both real public controls passed again:
+timeout 60.443 s wall / 59.970344 s CPU / 3,078,295,552 B peak; default control
+63.574 s / 63.177884 s / 3,189,719,040 B. Analytical results, identities, coverage,
+BPE and exact CLI/MCP parity remain unchanged. JSON identifies the runtime and
+verifier source manifests for each cohort and keeps all earlier receipts.
+
+Static `cl100k_base`/tiktoken 0.12.0 projections include the selected or complete
+name/description/inputSchema catalog, requests and structured Evidence or parsed
+text errors. Complete-tool-reply alternatives include MCP text/structured
+duplication. The selected two-tool catalog is 5,570 BPE; the complete projection
+is 195,522. Output schemas, host rendering/replay, notifications, model reasoning,
+final answers and billing are unmeasured. Repeated rounds, export, CLI parity,
+tokenization and exported-parent diagnostics are validation overhead outside the
+defined task tokens but inside resource receipts. Removing unsupported claims
+from the incorrect timeout baseline earns no efficiency credit.
+
+## Verification and limitations
+
+The initial production fix had 49 distinct passing cases across eight files. The initial
+pre-progress-cleanup seven-file selection passed 44/44. After progress cleanup,
+the same selection passed 43 and hit the existing 30-second test deadline in one
+native identity case; an unchanged two-file rerun passed both native cases and
+five public CLI cancellation cases. The original deadline was not increased.
+The runtime verifier collects interruption-bearing scopes; separate regressions
+cover native caller exclusion and malformed structured data. Source selection,
+malformed structures, actual worker resource constraints,
+retained large partial observations, cancellation/publication/cleanup, native
+identity and both public adapters remain covered.
+
+The first review found that the real verifier previously accepted any non-JavaScript
+operation with artifact-byte authority and ignored phase-entry status. The
+scenario now supplies exact operation/status expectations independently of the
+production phase map. Six additional oracle cases use the actual retained
+Joplin snapshots and reject wrong metadata operations, entered or missing
+statuses, and absent or conflicting gaps. They passed, bringing the distinct
+coverage to 55 cases across nine files. The production implementation did not
+change during this review correction.
+
+After the shared semantic-boundary correction from the second review, 78
+distinct cases passed across ten files: the nine-file selection passed 65/65,
+and the original root reconstruction file passed 13/13. This includes the
+alternate-builder owning test file's 23 cases. The new producer-boundary
+regression checks both construction paths, all five excluded metadata/native
+kinds, and selected/excluded JavaScript controls. Real Joplin controls exercise
+the public incremental workflow; the alternate full-builder path has filesystem
+boundary verification rather than a separately measured real-app workflow.
+
+Recorded attempts also include the verifier's initial non-null-subject assumption
+and an invalid top-level semantic-module-path absence check. Both were corrected
+before their assertions were used as proof. Corrected cancellation reproduction
+shows the actual native AST scope and phantom module on the baseline. Final
+source and execution-driver versions, source pins, input digests, prior attempts
+and resource receipts are in the [compact JSON record](javascript-interruption-applicability-2026-10-15.json).
+
+Before review, `npm run check && npm run docs:check` passed, including five consistency

+# Native handoff byte-identity verification
+
+Tracks #3926 under #4027. Baseline: `9f8659e0536e4e50a438f5b9d5661f3c9624f6ac`.
+Final integration base: `62bf09809ef7bb224028916424f8f07652a20f4f`.
+
+The analyst already knows an ASAR-relative native path and supplies prior native
+Evidence. The question is which Evidence can be linked to that component's exact
+bytes. Discovery and native-provider execution are outside this task.
+
+## Observed behavior and correction
+
+The native-node producer distinguishes a content digest from a canonical path
+whose bytes are unavailable. Its unavailable observation legitimately cites the
+containing archive. The handoff consumer previously treated that supporting
+artifact digest as the native component's digest.
+
+Public CLI/stdio MCP regression: the missing-companion case failed and the
+available-byte control passed. Real Joplin reproduced the same result: missing
+keytar bytes produced an `evidence-linked` handoff with the ASAR digest and the
+simulated container observation. CLI/MCP agreed on that incorrect answer.
+
+The consumer now uses only the node owner's content-digest identity. The fallback
+observation scan is removed. Unavailable native nodes retain their canonical
+path, availability, container-backed provenance and partial coverage in the
+inline graph; they yield no false actionable handoff or native Evidence link.
+An empty handoff list describes eligibility, not absence of native components.
+The per-query node index is allocated only after an eligible target exists; no
+persistent cache, schema, tool or target authority is added.
+
+Final real checks passed both cases with exact CLI/MCP trace parity. The available
+control preserved the complete parent/trace Evidence IDs, native facts, links,
+coverage and all token projections. The missing control preserved its parent,
+native node, source provenance and coverage, while removing the wrong handoff
+and container Evidence link.

+Verify the asset digest above before extraction. The ASAR is 233,575,014 bytes,
+SHA-256 `767df409b18effe60421fbefcca873de237c7e813eac744ecdeebbc5e825a33a`.

+`0700016bcd761cbe02d275f2046c7cc42f39f730a50d66e3d3307aa9d413373a`.
+All extracted component hashes are in the JSON record. 7z reported one
+trailing-data warning for the AppImage's embedded SquashFS and exited 0.
+
+Both cases select only `package.json` for static source analysis while retaining
+the inventory. The available case stages all three native companions; the other
+43 unpacked entries are not staged. The missing case stages none. Whole-application
+coverage is therefore partial in both cases, independently of the selected
+native component's known or unknown byte identity. Neither the application nor
+a native analysis provider is executed. Native Evidence is explicitly simulated
+to test exact subject linkage. Live Electron, real Ghidra/Hopper/IDA behavior and
+Windows/macOS verification are **NOT_ENOUGH_INFO**.
+
+## Reproduce the public workflow
+
+Use pinned Node 24.18.0/npm 11.16.0, `npm ci`, then `npm run build:cached`.
+The verifier returns compact records and deletes its private exported parent and
+CLI input after owned cleanup. No downloadable application or large Evidence is
+archived.
+
+```sh
+for mode in available missing; do
+  node scripts/verify/javascript/native-handoffs.mjs \

+    --source-path package.json --rounds 3 --cli-parity --require-safe
+done
+```
+
+Add `--tokenizer-python /absolute/path/to/python-with-tiktoken-0.12.0` for the
+reported BPE projections. The npm alias `verify:javascript:native-handoffs`
+builds first; recorded costs use the direct Node invocation above after building.
+For a pre-fix observation, run the saved verifier on the baseline build without
+`--require-safe`; `safe_identity: false` is an incorrect answer, not a passing
+analyst task. Paths affect serialized requests and some Evidence identities.
+
+The exact resource runs additionally used the preserved
+[8 GiB observer](https://github.com/morluto/rea/blob/b3bdabab694af1f9801eff7caf75001b92314a58/experiments/analysis-efficiency/resource-run.py)

+Whole-verifier resources include input hashing, analysis, three retained trace
+queries, export, CLI parity and tokenization. One CPU, 8 GiB hard cap, 6 GiB early
+stop, no swap; cleanup verified and no OOM. Memory includes charged file cache,
+not summed RSS. Counters are at payload exit while the observer remains alive.
+The available control's final wall and CPU times are substantially higher than
+baseline. Earlier post-fix controls on the original base took 61.657/74.956 s wall
+and 61.135962/60.352428 s CPU for available/missing cases; their complete receipts
+remain separately recorded. The final missing case took 59.738 s wall. This
+variability is unresolved and cannot be attributed to the native consumer change.
+These runs establish neither speedup nor performance equivalence. Input hashing warms the ASAR
+cache, build/OS caches and shared-host scheduling are uncontrolled. Fresh MCP
+sessions do not establish OS-cold conditions. First post-analysis and repeated
+warm-query samples are preserved separately; query CPU/memory are unmeasured.
+
+One defined task is one analysis summary plus one retained trace, with the path
+and prior Evidence already supplied. Static `cl100k_base`/tiktoken 0.12.0 counts
+include both requests, replies and name/description/inputSchema contracts:
+
+| Available-byte task, unchanged before/after     | BPE tokens |
+| ----------------------------------------------- | ---------: |
+| Selected catalog + structured replies           |     12,340 |
+| Selected catalog + complete tool replies        |     18,906 |
+| Full catalog projection + structured replies    |    202,292 |
+| Full catalog projection + complete tool replies |    208,858 |
+
+These are alternative reply/catalog projections. The selected catalog alone is
+5,570 BPE; the full projection is 195,522. Output schemas, annotations, host
+rendering/replay, reasoning, final answers and model billing are unmeasured.
+Repeated queries/export/CLI/tokenization are validation overhead outside this
+one-task token count, but inside resource receipts. Missing-case structured-task
+counts change 11,372 → 11,103 by removing unsupported claims; the incorrect
+baseline earns no efficiency credit.
+
+## Regression and verification record
+
+The initial four-file focused selection passed 24 tests. The two public cases
+were rerun after adding named summary-result parsing and correcting an optional
+architecture factory input. Omitting that field instead of passing null produced
+byte-identical normalized simulated Evidence in all four real-case inputs.
+The initial CLI-selector harness error and first typecheck failure are retained
+as harness/validation attempts, not product reproductions.
+
+After syncing the reviewed upstream changes, the updated application workflow
+CLI acceptance file passed 34 tests, bringing the focused selection to 58 distinct
+cases across five files. Both Joplin controls were then repeated on the final
+integration base. Canonical byte identity is also used by the related version
+matching/content comparison consumers; no equivalent observation-digest fallback
+was found there.
+
+Final `npm run check && npm run docs:check` passed on the integration base,
+including five documentation consistency tests: 128.732 s wall, 115.518920 s CPU,
+4,301,684,736 B peak cgroup memory, clean owned exit and no OOM.

+## Contract and ownership
+
+`inspect_analysis_view` / `rea inspect-analysis-view` accept
+`view.kind: "javascript-facts"`. `where.paths` matches only original Evidence
+artifact-path or source-range source strings; no filesystem lookup, normalization
+or property/display-path fallback. Omission includes unknown locations; `[]`
+matches none. Optional `where.kinds` selects original node kinds.
+
+Required `property_keys` selects original observation properties; `[]` returns
+identity and provenance only. Missing keys remain omitted, distinct from null.
+`include_available_property_keys: true` lists sorted original property names for
+returned rows without unselected values. It defaults to false. There is no
+cross-observation merging or semantic inference. Each row preserves its node ID,
+identity, observation ID, source-map reference and complete original Evidence.
+
+A single scan retains only the requested page. Caller-selected offset/limit are
+preserved; existing transport admission still applies. Coverage counts matching
+observations, while shared application/semantic source coverage, unknown counts
+and caller source selection describe the retained parent. Exhausting a page is
+not a claim of globally complete analysis. Full Evidence remains exportable.
+The domain projector and shared application service own both CLI/MCP behavior;
+no new provider, executor, persistent cache or live-state freshness claim exists.

+Stage all three native companions as in that procedure; the other 43 unpacked
+entries remain unstaged. No downloadable app or large Evidence is archived.
+
+The five selected sources are `ElectronAppWrapper.js`, its `.map`, `index.html`,
+`package.json` and `node_modules/keytar/build/Release/keytar.node`. Inventory
+covers 6,324 files; whole-application analysis remains partial. Normal processing

+
+Add `--analysis-timeout-ms 1` to both modes for the interruption control,
+`--cli-parity` to view mode for exact complete Evidence comparison, and
+`--tokenizer-python /absolute/python-with-tiktoken-0.12.0` for BPE projections.
+For field discovery, use `property_keys: []` and
+`include_available_property_keys: true` in both modes. The export baseline runs
+the recorded independent selector as an owned shell/Node caller program; it does
+not import the production projector. Later export samples reuse the same
+immutable export. View samples precede diagnostic export and CLI verification.
+
+All costly commands run serially with the preserved
+[resource observer](https://github.com/morluto/rea/blob/b3bdabab694af1f9801eff7caf75001b92314a58/experiments/analysis-efficiency/resource-run.py)

+Memory is peak process-family cgroup memory including file cache. At-answer
+counters include observer/startup, before repeat/parity/tokenization work; final
+external receipts include that verification work and are explicitly measured at
+payload exit while the observer remains alive, not final whole-scope counters.
+
+## Costs and interpretation
+
+The original completed normal baseline retrieved the selected facts in 2.981 s
+(first export plus projection), versus 0.157 s for the initial view; warm reads
+were 1.475/1.146 s versus 0.056/0.046 s. Both returned the same 12 observations,
+properties, original Evidence and parent coverage. The 1 ms interruption control
+returned the same 11 observations. CLI/MCP complete view Evidence matched exactly.
+The earlier slow baseline interruption run is preserved, rather than discarded.
+
+This is **not an established token improvement**. Counting selected input
+contracts, preparation, requests and structured replies, normal baseline BPE was
+8,887 versus 17,289 for the initial view. The existing general view contract and
+Evidence wrapper cost more than the caller code saved. Counting the full
+name/description/input-schema catalog instead gives 188,206 versus 189,954.
+These are `cl100k_base` counts, not billing or model context measurements; output
+schemas, exec schema and host rendering are unmeasured. Final same-backend
+controls and optional-discovery measurements are recorded separately in JSON.
+
+Actual Codex CLI trials use the runnable
+[agent harness](../../experiments/analysis-efficiency/javascript-facts-agent.mjs),
+installed CLI 0.161.0, requested alias `gpt-5.6-terra` / high, unchanged questions
+per pair, and fresh processes/MCP. Restricted baseline tools are analysis and
+export; candidate adds the existing `inspect_analysis_view`. Both can reach the
+same backend information through export. Shell projection is allowed only on
+retained exports; target execution, raw ASAR shell inspection, downloads,
+repository investigation and other agents are forbidden in both.
+
+```sh
+node experiments/analysis-efficiency/javascript-facts-agent.mjs \
+  --repository /absolute/rea --artifact "$input_root/cases/available/app.asar" \
+  --arm view --task direct --output /absolute/new-result-directory
+```
+
+Run each `direct`, `partial`, `negative` task with both `export` and `view` arms,
+serially under the same resource observer. The negative task tests the claim
+that a static byte digest establishes native execution. Existing normal auth is
+used with `--ignore-user-config`; no credential copying or HOME/CODEX_HOME
+mutation. The installed CLI requires `code_mode_host: true` for all dispatch;
+that frontend setting is identical in both arms and is not a new REA executor.
+Experimental `code_mode` / `code_mode_only` remain disabled. MCP tool allowlists
+and per-tool settings use the [official Codex configuration](https://developers.openai.com/codex/mcp).
+Historical harness patches preserve the invalid disabled-host attempt and the
+initial working harness; the former is excluded as a harness failure.
+
+Initial direct baseline: 332.9 s, 741,744 cumulative input tokens, 17 operations;
+initial candidate: 182.2 s, 405,267 input tokens, 10 operations. The candidate
+still exported, guessed several property names, and gave a qualified phase
+answer that mixed missing original content with processing gaps. The follow-up
+with opt-in field-name discovery used it correctly but still exported: 343.1 s,
+835,185 input tokens and 17 operations. Its normal phase answer was correct.
+All attempts remain recorded; selecting only the better initial candidate would
+misrepresent the result. Cumulative input includes repeated cached context and
+is not peak context. Requested model alias does not prove the underlying model;
+USD, peak context, model scheduling and cache effects are unmeasured.
+
+The capability is useful as a precise, bounded retained-data interface for
+clients that know their question. These small agent trials do not justify a
+universal recommendation, a token-saving claim, or production code mode.
+Property discovery is opt-in because even field-name metadata costs context.
+No cross-platform/live-browser/native-provider compatibility is established by
+these static Linux Joplin checks.
+
+## Validation and retained failures
+
+The final focused source set has 85 passing cases across four files, including
+public MCP real-filesystem selection/paging/null/identity semantics, portable vs
+retained complete Evidence parity, advertised SDK schema validation, malformed
+selectors, literal artifact/source-range/URL distinctions, unknown locations,
+empty filters and opt-in names without large unselected values. Distinct SDK
+schema/presentation checks, full static/docs gates and real final controls are
+listed with their final executed results in JSON.
+
+Initial test fixtures incorrectly encoded invalid artifact/unknown locations and
+omitted a required partial-graph limitation; these were fixture failures, not
+product reproductions, and were corrected without relaxing the domain contract.
+The initial static gate found two unreferenced verifier files; a real npm
+verification entrypoint fixed discoverability without ignores. Later full V1
+static/docs and 16 SDK schema/presentation tests passed. The final-version gates
+are recorded separately; prior checks are not substituted for them.
+

+The partial candidate returned exact retained phase entries using four MCP calls,
+without export or shell. It used less input context but more CPU and wall time
+than the corresponding export baseline. Both negative-task arms preserved runtime
+execution as unknown; the candidate still exported once. The one invalid
+disabled-host attempt (37.679 s / 5.070758 CPU s / 880,414,720 B) is preserved

+also mixed true missing original content with unavailable processing phases.
+The API itself preserves node/observation pairs; these are qualified agent
+composition outcomes, not a claim of product provenance corruption.
+
+Pre-integration V2 source validation passed: full `npm run check`, generated metadata/docs
+checks, five documentation consistency cases, test discovery, and 18 MCP cases
+(two expanded facts cases plus 16 SDK schema/presentation cases). Together with
+the unchanged 83 domain/application/MCP cases passed on V2, this establishes
+101 distinct focused cases across six files. The final combined gate took
+182.620 s wall / 182.170929 s CPU / 4,288,471,040 B peak cgroup memory, with no
+OOM and verified cleanup. Exact command and receipts are in JSON. That pre-integration
+runtime tree matches the V2 agent-trial runtime tree exactly; formatting and
+added validation did not change that built backend.
+
+## All pre-integration scripted workflows
+
+Each row uses a fresh MCP process; warm samples reuse its retained parent or export.
+The first-answer wall clock includes input hashing/catalog/preparation; CPU and memory
+are scope counters at that answer, before repeat/diagnostic/CLI/tokenization work.

+
+All ten workflows passed their independent export oracle. Known-field normal pairs
+return the same 12 observations; interrupted pairs return the same 11. Opt-in
+field-discovery pairs return the same original property names for 12 observations
+without selected values. All four measured view workflows passed exact complete
+CLI/MCP Evidence parity (initial normal/timeout and final normal/timeout), and
+the final discovery view passed it too. Canonical selected-answer digests agree
+across corresponding export/view pairs; raw serialization digests may differ by
+JSON property order. Final runtime/source and payload cleanup receipts are in JSON.
+
+Final normal selected-contract cost is 8,928 BPE for export/projection versus
+17,393 for the view. The full catalog projection is identical between final
+arms; view Evidence wrapping still adds cost. Faster retrieval is useful, but
+fewer bytes/calls alone cannot establish lower whole-agent tokens or latency.
+
+After the final documentation clarification and measurement tables, generated
+docs/checks passed again (including five consistency cases). Duplicate scanning
+and TODO checks passed; final runner/grader syntax and all three historical
+harness reconstructions were verified against their recorded SHA-256 values.
+No tech-debt markers were introduced. These final audit receipts are retained
+separately from backend task performance.
+
+## Main integration on 2026-10-15
+
+The measured V2 checkpoint is
+`d32547f9ac7769049a8ee6fbc8a27abcb2285a54`. Main advanced during the trials;
+merge `5f0b1fa47ffdf25b3775d87c2e07aea6cff26f31` integrates pinned current main
+`2202e3f0ba556d40cc6e598df1ecbdf1eda56c13`, including independent semantic
+value/lifecycle fixes. Historical cohorts remain valid for their pinned backend,
+not measurements of the later integrated backend. Integrated normal/interruption
+export/view controls and the complete focused/static/docs gates are recorded
+separately below and in JSON when executed. No agent pilot rerun or universal
+token/latency benefit is inferred from that source update.
+
+Integrated checks passed: all **101 focused cases in six files**, full static
+checks, generated docs/metadata, five consistency cases and test discovery.
+The combined gate took **247.955 s wall / 247.425940 s CPU / 4,303,970,304 B**
+peak cgroup memory; no OOM and verified cleanup.

+
+All four integrated controls passed their independent export oracle; both view
+cases passed exact complete CLI/MCP Evidence parity. Normal/timeout selected
+facts and source coverage also match the V2 checkpoints. Temporary export paths
+can change a few request BPE tokens; exact requests are measured, not normalized.
+The new runtime contains 1,633 JS files, tree SHA-256
+`6a5763452c1522a782e531e6dda227ea10140f9f9d52148fc1602a6ecf3cea5a`
+under the explicit compact sorted path/hash algorithm in JSON. Agent-trial
+runtime pins remain separate. These controls do not justify a causal speedup
+or whole-agent token claim.
+
+## Review: experiment metadata and failure ownership
+
+Greptile review on `7238fd080` found two valid runner defects: a hardcoded CLI
+version, and a `finally` error which hid command/diagnostic failures. The runner
+now probes `codex --version` through the existing owned-command boundary before
+starting an agent, and records the observed output in successful/failed trials.
+Probe failure or empty output stops the trial. The local real-command smoke
+returned `codex-cli 0.161.0`; historical trials retain their original metadata.
+
+Cleanup retains the original `OwnedCommandFailure` or diagnostic-write aggregate,
+its cleanupResult/resources, the unresolved cleanup owner and private workspace.
+Shared `closeVerifierResources` combines a separate root-cleanup failure with
+the primary error. Snapshot diagnostics use actual retained/observed byte counts,
+not nonexistent stream `truncated` fields. Signal handlers remain installed
+through final cleanup; late cancellation preserves completed trial data and
+returns typed cancellation. Success is printed after finalization.
+
+Eight deterministic cases exercise the real experiment entrypoint, production
+private-root creation/removal and `OwnedCommandFailure`, with controlled command
+and cleanup outcomes: observed version, failed/empty version, retained owner,
+recording failure, root cleanup failure, ordinary timeout, nonzero exit and late
+cleanup-time cancellation. No model, application or orphan process is launched
+by these cases. The baseline exposed the original errors; an intermediate failed
+assertion assumed Node omitted `[Error]` when printing the class and was corrected
+to check the original class/message independently. All attempts remain in JSON.
+
+The final eight cases passed, followed by the complete Python suite (35 bridge
+plus71 experiment cases:106 total, including the eight new cases). Full static,
+docs/five consistency and test-discovery checks passed again; all four historical
+harness patches reconstruct their recorded hashes. At that review-fix checkpoint, the backend remained the integrated 1,633-file
+tree above; no model trial or real-app analysis was rerun for those runner-only
+corrections. The following lifecycle integration is a separate backend version.
+The fourteen historical real-app answers retain their original versions.
+
+```sh
+python3 -m unittest discover -s experiments/analysis-efficiency \
+  -p test_javascript_facts_agent.py -v
+npm run test:python
+```
+
+## Lifecycle-main integration on 2026-10-16
+
+Upstream #4274 merged as `1b97b0f3707b1cf78ac98bd4ae81638b33cc286f`.
+Merge `2ca63f4d9f2e489ce3b5cbccdc204ad0be39551c` integrates it without
+changing the retained-facts implementation. Locked dependencies were reinstalled.
+The current runtime contains **1,645 JS files**, compact sorted path/hash tree
+`311fd78c7ca4717e56253413bc2725097929e0d6656efca69c9b3646a65ca348`.
+The JSON preserves both earlier runtime/source manifests and all historical
+trials. No model trials were rerun.
+
+Full static, generated docs/metadata, five documentation-consistency cases,
+test discovery and all **106 Python cases** passed. The initial combined command
+returned exit 1: **113 focused cases passed and one contract-order fixture hit its
+20-second subprocess budget**. It took 483.978 s wall / 386.555153 s CPU /
+5,169,971,200 B peak cgroup memory, with no OOM and verified cleanup. An isolated
+CPU-15 retry also failed at that deadline. These attempts remain failures in JSON.
+The original unmodified test then passed on one CPU 10 in 11.446 s, retaining its
+20-second deadline; its complete wrapper took 13.545 s wall / 13.272853 s CPU /
+920,023,040 B peak. Thus **114 distinct focused cases across seven files passed
+across the documented invocations**, including the previously failing ADB case.
+This does not describe the initial combined command as successful.
+
+Four fresh controls use the same one-CPU/8-GiB wrapper, explicitly selecting CPU
+10 because CPU 15 was observed fully busy while this task was idle. Memory
+includes file cache. First-answer counters precede diagnostic exports, repeated
+queries, CLI parity and tokenization; external scope receipts include that extra
+verification. Caches and host scheduling remain uncontrolled.

+
+All four passed the independent current-runtime export oracle. Both view cases
+passed exact complete CLI/MCP Evidence parity. Normal results retain the same
+12 original observations and their complete per-row Evidence. Their parent
+Evidence changes with `semantic_unknown_count` 41,161 → 41,162; the additional
+unknown was not individually isolated. Both current workflows report the same
+current coverage, rather than projecting the historical count. Interrupted
+results retain the same complete 11-row answer, parent and coverage as before.
+There are now 18 version-labelled manual workflows and nine complete view
+CLI/MCP parity controls. Historical agent measurements do not become claims
+about this newer backend.
+
+The normal selected structured task still costs more BPE for the view
+(17,421 versus 8,947), while its first retrieval is smaller in this cohort
+(152.862 versus 4,241.377 ms). No causal speedup, portable equivalence or universal
+token benefit follows from these single-cohort measurements.
+
+Final `check:fast`, `docs:check` and five consistency cases passed again:
+43.728 s wall / 41.873577 s CPU / 814,235,648 B peak. All 16 authored source
+hashes and the measured runtime tree still match.
+
+### Default-client compilation diagnostic
+
+The pinned SDK client 2.3.1 builds its output-validator index by compiling every
+cached `tools/list` output schema on the first `callTool`. A CPU profile and
+read-only instrumentation located the fixture delay there; PNG comparison and
+cleanup were not the expensive stages. The completed default-client fixture
+passed the original catalog and response assertions: 207 tool schemas and 16
+named responses. This replay does not turn either timed-out Vitest run into a
+pass. No SDK, production code, fixture, or test deadline was changed.
+
+A separately built main-only worktree at `1b97b0f37` also compiles the complete
+catalog. Its fixture took 11.598 s wall / 11.262708 s CPU; the candidate diagnostic
+took 24.899 s wall / 12.364085 s CPU. CPU-15 saturation, different transient
+scheduling and warm caches prevent a causal wall-time comparison. The
+`inspect_analysis_view` output schema grows from 128229 to 137174 compact UTF-8
+bytes; that additional client work remains a cost of the additive contract.
+The sampled profile attributes substantial wall samples to SDK AJV compilation
+and GC; these samples are not CPU-time attribution. Raw catalogs and CPU profiles
+are reproducible diagnostics and are not archived. Their hashes and compact
+results remain in JSON.
+
+Reproduce the profile against either pinned checkout after its locked install
+and runtime build, within the resource wrapper above:
+
+```sh
+node --cpu-prof --cpu-prof-dir=/tmp/rea-contract-profile \
+  tests/fixtures/contractPresentation.mjs reversed > /tmp/rea-contract-result.json
+```
+
+To identify individual compilations on the pinned SDK, preload this diagnostic
+from an ignored checkout-local `.cache/contract-compile-probe.mjs`:
+
+```javascript
+import { Client } from "@modelcontextprotocol/client";
+const compile = Client.prototype._compileOutputValidator;
+Client.prototype._compileOutputValidator = function (tool) {
+  const started = performance.now();
+  try {
+    return compile.call(this, tool);
+  } finally {
+    console.error(
+      JSON.stringify({
+        name: tool.name,
+        compile_ms: performance.now() - started,
+      }),
+    );
+  }
+};
+```
+
+```sh
+node --import ./.cache/contract-compile-probe.mjs \
+  tests/fixtures/contractPresentation.mjs reversed > /tmp/rea-contract-result.json
+```
+
+This private SDK hook is diagnostic-only and version-specific. It is not a REA
+execution surface or a proposed SDK fork. A client can separately evaluate the
+public per-call `toolDefinition` option without reducing catalog completeness
+or changing backend authority; no such client change was made here.

+# Local constant BrowserWindow options — Joplin verification
+
+This record covers #4366, part of #3536 and #4027. The unchanged official Joplin desktop 3.7.21 ASAR contains `const windowOptions = {...}` at `ElectronAppWrapper.js:238–263`, an unrelated conditional `icon` assignment, and `new BrowserWindow(windowOptions)` at line 268. The scoped public workflow analyzes that source plus `package.json`, then reads the window through `inspect_analysis_view`. It does not execute Joplin.
+
+The baseline returns one dynamic window with zero explicit preferences. The candidate retains four literal booleans (`nodeIntegration: true`, `contextIsolation: false`, `spellcheck: true`, `enableRemoteModule: true`) and the explicit dynamic `session` expression. The original window identity and constructor location are preserved. Constant association is inferred, with the original object's source range; omitted preferences do not acquire Electron defaults. Popup overrides and literal spreads remain separate work under #3536.
+
+The [compact measurements](javascript-window-options-2026-10-16.json) retain both trial orders, exact inputs, runtime/harness/source fingerprints, original result rows, CLI/MCP Evidence parity and observer receipts. ASAR SHA256 is `767df409b18effe60421fbefcca873de237c7e813eac744ecdeebbc5e825a33a`; the 39,972-byte source is `dcd2260e46dd1b4922449090e268773b052d58ba24ff977b08b978bee6cc9da1`. Download/recreation provenance is in the [earlier Joplin record](javascript-retained-facts-2026-10-15.md). Downloadable applications and complete exports are not committed.
+
+## Correctness
+
+Both trial pairs match the independent export-and-filter oracle and exact complete CLI/MCP view Evidence. The pinned [Joplin checker](../../experiments/analysis-efficiency/joplin-window-options-check.py) verifies exact settings, explicit unknowns, source ranges and stable window identity. Manual negative controls reject a wrong boolean, numeric0 substituted for false, a changed identity and observed instead of inferred provenance.
+
+A raw semantic graph digest changes because the semantic graph commits its parent `application_graph_id`. The final record separately checks complete semantic content after excluding exactly that foreign key and its dependent top-level `graph_id`; original raw digests remain recorded and linked to the independent complete CLI observations. These exclusions follow the canonical semantic graph schema and builder, rather than filtering differing nodes or relations.
+
+## Costs and limitations
+
+| Trial order             | Variant   | First answer (s) | CPU (s) | Peak cgroup bytes at answer | Projected task BPE |
+| ----------------------- | --------- | ---------------: | ------: | --------------------------: | -----------------: |
+| Baseline then candidate | Baseline  |           70.283 |  69.258 |                  1578196992 |              13337 |
+| Baseline then candidate | Candidate |           42.701 |  42.437 |                  1523793920 |              13432 |
+| Candidate then baseline | Candidate |           44.793 |  44.766 |                  1527357440 |              13432 |
+| Candidate then baseline | Baseline  |           42.958 |  42.946 |                  1533308928 |              13337 |
+
+The baseline tool workflow cannot supply these settings; additional manual source-reading costs are unmeasured. This is a correctness gain with +95 projected structured-task tokens (+203 when counting complete tool replies). Both use the same 8,069-token selected catalog. The first apparent latency gain does not repeat: the reversed pair makes the candidate about 1.8 s slower. These samples establish no speedup or general performance result. First view retrievals are 106–121 ms; subsequent within-session reads are 22–35 ms. No persistent analysis cache was added.
+
+All costly jobs run serially with one CPU 10, an 8 GiB hard limit, 6 GiB early stop, no swap and 192 tasks, pinned Node 24.18.0/npm 11.16.0. Cgroup memory includes file cache and is not RSS. At-answer counters precede repeated reads, diagnostic export, full-graph hashing, CLI parity and tokenization. Whole-verifier observer receipts measure that extra work separately. The observer reported no OOM and verified payload cleanup in each scoped run.
+
+Each task starts a fresh MCP process; the input hash warms file cache, and build/OS caches are uncontrolled. Three retrieval samples are not three cold analyses. `cl100k_base`/tiktoken 0.12.0 projections include preparation, first answer and selected input schemas; output schemas, actual billing, reasoning, peak agent context, host rendering and system-cold behavior were not measured. No live-model or Electron runtime claim is made.
+
+## Validation and reproducibility
+
+The integrated focused invocation passed 156/157 cases across 9 files. An unchanged upstream generator CLI/MCP case exceeded its original 30 s deadline in grouped execution; isolated runs at that same deadline passed on both main and candidate (18.590/18.034 s). The grouped failure is preserved; its root cause is not established and its deadline was not changed. Own CLI/MCP/fact-view, source mutation/escape/identity and capacity regressions passed. Static/document checks are recorded in the JSON validation receipts.

+An initial real-app verifier attempt failed because its coverage assertion handled only artifact paths. The independent selector and tool already supported source-range paths. The verifier assertion was corrected before both valid pairs; that failed attempt is excluded from performance samples. The source oracle's initially transcribed closing line 264 was corrected to 263 after rereading the unchanged source. Neither correction changes production analysis.
+
+After building the pinned baseline and candidate in separate checkouts, run this same command serially in baseline→candidate and candidate→baseline order, using the matching harness hash recorded for each pair:
+
+```sh
+query='{"kind":"javascript-facts","where":{"paths":["ElectronAppWrapper.js"],"kinds":["browser-window"]},"property_keys":["options_status","web_preferences_status","web_preferences","preload_path","resolution_sources"],"offset":0,"limit":64}'
+node scripts/verify/javascript/retained-facts.mjs \
+  --artifact /absolute/path/to/app.asar --mode view --query "$query" \
+  --source-path ElectronAppWrapper.js --source-path package.json \
+  --rounds 3 --cli-parity --tokenizer-python /absolute/python-with-tiktoken-0.12.0
+python3 experiments/analysis-efficiency/joplin-window-options-check.py \
+  docs/verification/javascript-window-options-2026-10-16.json
+```
+
+Apply the linked resource observer from the earlier Joplin record to each costly command. Complete CLI observations use the same source selection through `analyze-javascript-application --format json`. The preserved [content comparator](../../experiments/analysis-efficiency/compare-javascript-semantic-content.mjs) takes the baseline CLI JSON, candidate CLI JSON and this measurement record, then emits the semantic proof while retaining both original graph identifiers and raw digests. It reads sequentially and reports a concise failure rather than printing full graphs. The baseline backend is unchanged main `2c7583599b9ac1c847bd77b1940930fd8d4594c7`; only the matching verification harness is applied there. Source and runtime pins distinguish measurement versions from later documentation changes.
+
+## Ordering review follow-up
+
+Codex review identified an introduced producer-ordering regression: inline windows were appended during traversal while deferred constants were appended afterward. The new mixed constant/inline/unresolved regression reproduced `[4, 3, 5, 6]` instead of source order `[3, 4, 5, 6]`. The producing collection now restores order from retained source offsets before module attribution and public graph consumers; no downstream adapter repair was added. A reused options object remains dynamic after it escapes to the first constructor.
+
+After the fix, all 49 targeted cases across five files passed, including the public CLI/MCP/fact-view workflow and capacity/identity cases. One additional real Joplin run at source revision `3fd71cba2` returned exactly the same complete answer and semantic fingerprint as the original candidate, with complete CLI/MCP view Evidence parity. It took 44.028 s at answer / 43.960 CPU s / 1,524,555,776 peak cgroup bytes, with the same 13,432 projected task tokens. This is a follow-up validation, not an additional paired latency comparison. The JSON stores its runtime and current source pins separately; the original trial receipts and historical source pins remain unchanged.
+
+## Shared query performance review follow-up
+
+The stored-alias example raised in review already returns unknown on the reviewed production code: the exact negative source case passes, and the public CLI returns one dynamic window with zero explicit preferences. The shared `reference-store` producer records the assignment escape before construction. No mutation rule was changed; the negative regression is retained.
+
+The repeated-effects cost was reproducible. Candidate discovery needed only lexical identity but collected full mutation reports; each later capture also materialized every effect before checking for a prior escape. The shared index now offers lexical-only lookup and an early-exit predicate. Windows and request analysis use those operations. The same owner still supplies complete effects to the require-source consumer, which needs filtered effect kinds; no second interpretation or persistent cache was added.
+
+The [preserved scaling control](../../experiments/analysis-efficiency/window-option-scaling.mjs) measures real production source analysis on synthetic capacity inputs; it is not a real-application or agent task. All samples and module hashes are retained. CPU medians across three sequential samples were:
+
+| Shared-options constructors | Before (CPU s) | After (CPU s) |
+| --------------------------- | -------------: | ------------: |
+| 256                         |        0.29703 |       0.17821 |
+| 512                         |        0.96105 |       0.08709 |
+| 1024                        |        4.41298 |       0.20032 |
+
+The first 256 sample is the first algorithm execution in each process; later rounds and larger sizes can use warmed V8 code. These medians mix that progression and do not establish cold-task scaling across applications. A deterministic regression separately bounds escaped-effect reads for 128 captures to at most 4N while requiring unindexed unknowns, a valid first capture and unknown reused contents. Timing is not a test gate. Reproduce the capacity control, after building each pinned checkout, with `node experiments/analysis-efficiency/window-option-scaling.mjs LABEL 256,512,1024` under the same resource observer.
+
+After this refactor, 107 cases across 10 focused files passed, including request CLI/MCP, require-source, worker-schema, identity, capacity and retained-fact workflows. A new real Joplin run at `9207ece2090208c272d2689c4002438ceda41145` preserves the exact whole answer and semantic fingerprint, including CLI/MCP parity and the same 13,432 projected task tokens. It measured 44.607s / 43.883 CPU s / 1,666,560,000 peak cgroup bytes. Thus the capacity improvement is clear for the tested pattern, while no general real-app speedup is claimed. The new stage stores current source/runtime pins and validation separately; all previous receipts remain unchanged.

+# Atomic RE through Code Mode
+
+This is an **in-progress experiment**, not an integrated provider release. Branch
+`experiment/atomic-codemode-20261016` starts at main
+`42fc6c53ae188978deb3bedfe88287b6b316ba22` and carries the previous atomic-facts
+prototype. Historical measurements in `../atomic-re-tools/` retain their original
+baselines. No PR or merge is intended.
+
+The branch was subsequently [refreshed from main `60bf10245`](main-refresh-study.md).
+Shared installation/file cleanup and string parsing now follow that main's
+owners. Historical model measurements retain their original frozen runtimes;
+the refresh has separate real-provider verification and resource receipts.
+
+The goal is a real model completing reverse-engineering questions through
+composable facts, with Code Mode as the calling adapter. A configured feature flag,
+a scripted verifier or a small response does not prove that goal.
+
+The [capability map](capability-map.md) distinguishes verified task coverage,
+experimental exporter requirements and remaining unknowns before interpreting
+adapter comparisons.
+
+The [string-span study](string-span-study.md) adds paged incoming occurrence
+queries for encoded object spans and independently verifies pooled suffix
+references on real SQLite. The same native sparse range index serves Kuna's
+existing string aggregates. Equivalent cold occurrence retrieval falls from
+48.1 to 1.8 seconds; this is shared analysis reuse, not a Code Mode result.
+The subsequent frozen real-model runs all answer the selected task correctly:
+traditional takes 315.6 seconds, Direct 102.3 and Code Mode 93.6. Code Mode uses
+less cumulative input but more uncached input and peak memory than Direct.
+Traditional's full inventory is truncated by the client; one original cited
+payload remains only partially auditable. The study preserves that limitation.
+
+The [string-fact precision study](string-facts-study.md) preserves native NUL
+termination as true/false/unknown through the shared domain and public output
+contract. Real canonical MCP, SDK, Direct, Code Mode and CLI checks retain both
+NUL-terminated strings and a nonterminated printable run without length-based
+agent inference. The old coarse descriptor remains compatible.
+Both fresh real models complete the same frozen task after this repair: Direct
+takes 95.2 seconds, Code Mode 90.9. Code Mode lowers cumulative input and peak
+memory but increases uncached input and CPU. The results do not isolate the
+metadata change's performance effect; all source and usage checks are recorded.
+
+The [large-result study](large-result-study.md) verifies that paging alone does
+not bound a large field. String metadata can now be selected without text, while
+SDK full reads remain available. Shared pre-allocation JSON checks preserve
+context and Evidence on transport refusal, including in-program Code Mode
+recovery. The synthetic fixture tests capacity; it does not establish real-app
+analysis quality. Real SQLite/SSH regressions are reported separately.
+The subsequent real Code Mode model passes the frozen capacity task. Direct
+retrieves correct data but labels two 17-byte prefixes as 16, failing the exact
+reporting criterion. Both use metadata selection without sending full blobs.
+Code Mode uses less input but more wall time; the differing correctness and byte
+window choices prevent a matched-quality efficiency ranking. All runs remain.
+The [streamed inventory study](streamed-inventory-study.md) then restores real
+FFmpeg queries whose complete native source exceeds 8 MiB, using the production
+streaming parser and bounded retained files. Real SDK/MCP lanes pass; LLVM and
+Node still exceed the existing 64 MiB budget. Those failures remain explicit.
+Both real models now complete the FFmpeg task with all cited raw captures
+verified. Code Mode uses less cumulative input but more uncached input and time.
+The study also retains two evaluator namespace failures and their full costs;
+the corrected pair uses actual registered tool discovery.
+The [refusal-cache study](capacity-refusal-study.md) then avoids repeated native
+work for proven immutable source-budget failures. Real SDK and both MCP adapters
+verify reuse and readable partial Evidence; cancellation/cleanup uncertainty
+remain uncached. The first Code Mode precondition failure and its cost remain in
+the record. Larger-target inventory coverage is still unresolved.
+
+The later [native query study](native-string-query-study.md) makes selected LLVM
+and Node string queries answerable without retaining a whole oversized inventory.
+Both frozen LLVM model answers pass; Code Mode uses fewer input tokens in that
+pair, with only a modest wall-time difference. The [shared byte checkpoint](byte-batch-study.md)
+then batches missing byte windows through one native program while retaining
+per-window facts and Evidence. A same-engine SDK toggle reduces ten-window cold
+retrieval from about 94.3 to 8.5 seconds. Real provider preflight passes; new model
+trials for this byte change were not run because the user cleared the goal.
+
+The [AArch64 reference study](aarch64-xref-study.md) finds and fixes missing
+ADRP-based string and memory references before the next model comparison.
+Real SDK and traditional MCP preflights now agree with independent machine
+evidence; the shared bounded producer preserves space/width and uncertainty.
+All three real models now complete the behavior-level task. Code Mode takes
+151.3 seconds / 388,365 cumulative input tokens, Direct 164.9 / 515,929 and
+traditional 345.7 / 681,613. Code has more uncached input than traditional and
+more memory than Direct. These are the earlier pinned measurements.
+
+The [return-coverage study](aarch64-return-study.md) subsequently fixes two
+independent producer defects: BTI import-entry identity and false no-return
+promotion that erased the post-warning path. All three fresh model answers pass
+the same selected task. Direct uses 351,157 cumulative input tokens / 139.0
+seconds, Code Mode 371,571 / 166.8, and traditional 662,683 / 263.1. Code Mode
+reduces MCP requests but adds model responses in this sample; correct primitives
+and fewer RPCs do not establish a stable adapter advantage.
+
+The [architecture storage study](storage-study.md) adds exact native register-name
+and address-space queries, sharing one bounded immutable capture per lease.
+It separates coordinates, widths and native map misses from hardware absence,
+SSA equality or alias claims. Both real SSH models complete the extended task;
+Code Mode uses 307,888 versus 415,450 cumulative input tokens and 142.2 versus
+158.1 seconds, but more local CPU. This single pair does not establish a stable
+advantage; the full typecheck gate remains resource-limited.
+
+The [function-boundary study](function-boundary-study.md) adds independent native
+prototype entries and return descriptors, separated from raw input varnodes.
+Both real SSH models correctly distinguish these inventories and compose the
+selected caller/parameter/helper transfer. Direct uses 331,674 cumulative input
+tokens / 118.4 seconds; Code Mode uses 359,789 / 125.7, with lower uncached input
+but mixed overall costs. Native and real-provider checks are recorded there.
+
+The [path-query study](path-query-study.md) adds a shared, bounded recovered-CFG
+witness query with exclusions and paging. Both actual MCP adapters verify the
+same four real SQLite witnesses without requiring the model to fetch the entire
+graph. This establishes graph-relative facts; predicate feasibility stays unknown.
+Both real models now use the query and answer correctly on the same frozen
+controller task: direct takes 200.8 seconds / 495,895 cumulative input tokens;
+Code Mode takes 203.3 seconds / 554,477. Code Mode has lower uncached input,
+but no stable overall advantage is established. All prior pairs stay reported.
+
+The [control-query study](control-query-study.md) verifies every derived control
+triple on the real SQLite VM, fixes unknown CFG seeds and reuses a lazy
+postdominator index. Its [two-level investigation](controller-oracle.md) is
+frozen before model runs and separates alternative path predicates, SSA identity
+and finite recovered-edge witnesses from runtime claims. Both real-model answers
+now pass: Code Mode reduces cumulative input but increases uncached input, time,
+CPU and memory in this pair. Correct facts support both calling strategies;
+the query-cache improvement is separate from those mixed whole-task costs.
+
+The [discovery-summary study](discovery-summary-study.md) addresses repeated
+metadata from that pair. The complete method index now uses owned intent
+summaries; all full contracts and advertised tools remain available. Contracts
+and session admission have separate owners, with native loading deferred to open.
+Its repeat uses the same frozen control question and retains the earlier results.
+
+That completed repeat again answers correctly in both lanes. The smaller index
+does not establish an overall task improvement: actual help use adds a Code Mode
+call, and cumulative/uncached tokens, local resources and end-to-end time have
+mixed changes. A large observed inter-call gap remains charged and unexplained.
+
+The [exact-value query study](value-query-study.md) adds location-to-value and
+value-to-operand-use queries, including inputs/constants without defining operations.
+Real stripped OpenSSH checks preserve all 250 SSA versions / 369 occurrences at
+one selected policy location while reducing an equivalent core read task from
+244 queries to six. A subsequent [real-agent OpenSSH comparison](ssh-warning-study.md)
+completes the same machine-supported task through all three interfaces, after
+correcting an incomplete traditional evaluator toolset. Atomic direct has the
+lowest measured costs in this sample, using machine facts without decompilation;
+Code Mode uses the new queries but takes extra analysis steps. General efficiency
+claims still require broader evidence.
+
+The reference is [Hex-Rays IDA MCP](https://github.com/HexRaysSA/ida-mcp/blob/df6de7985b534a964c125d5a86e41b26b17b14f6/ida_mcp/mcp.py):
+an on-demand `reference` lookup and an execution entrypoint over a richer analysis
+API. This experiment uses JavaScript and a QuickJS WASM environment rather than
+Python in the host process. It exposes only declared static analysis capabilities.
+It does not add target execution, patching or GUI control.
+
+Three boundaries own the implementation:
+
+- `provider.mjs`, `native-ir.mjs`: existing REA native target/process owners and parsed Kuna
+  string/reference/SSA facts, retained sources, freshness and cleanup.
+- `api.mjs`: named, validated fact/relationship contracts and their intent summaries.
+  `session.mjs` owns shared admission and lease/file cleanup, loading the native
+  provider only on open. SDK callers, CLI scripts and both MCP adapters use these
+  same contracts and application owner.
+- `executor.mjs`, `server.mjs`, `cli.mjs`: bounded JavaScript composition and
+  presentation. No analysis is reimplemented in the execution environment.
+
+The complete Code Mode MCP catalog is `open_binary`, `reference`,
+`execute_javascript`, `close_binary`. Setting `REA_ATOMIC_ADAPTER=direct` exposes
+the same fact API as `facts_*` MCP operations for comparison. This is a distinct
+experimental server; the production REA catalog is not filtered or replaced.
+
+Use the pinned Node, an existing REA build and a caller-supplied Kuna 1.833:
+
+```sh
+npm ci --prefix experiments/atomic-codemode --ignore-scripts
+node --test experiments/atomic-codemode/*.test.mjs
+REA_KUNA_COMMAND=/absolute/path/to/kuna node experiments/atomic-codemode/server.mjs
+```
+
+The local MCP registration for real model trials is named `rea-codemode`.
+`agent-trial.py --mcp-entrypoint /absolute/path/to/server.mjs
+--server-name rea-codemode --protocol-profile atomic --profile-parent /tmp` creates an isolated
+configuration, home and empty working directory for the model. Shell/file tools,
+web search and delegation are disabled. No repository or oracle is placed in that
+workspace. The copied authentication file is removed with the isolated profile.
+Model output, actual MCP calls, original errors and usage remain in the trial
+directory. `REA_ATOMIC_TRACE` and `REA_ATOMIC_EVIDENCE_DIR` retain actual API calls
+and complete sources outside the model workspace when explicitly selected by the
+evaluator. The ambient environment and credentials are not logged.
+
+Current bounds: 64 MiB guest heap, 32 KiB code and script value/error payloads, 64 host calls per execution,
+120 seconds wall deadline and 2 seconds of guest synchronous execution. Native
+requests use existing supervision and a 1 GiB function-memory limit. Buffered
+formats and diagnostics keep an 8 MiB bound; string inventories stream through
+the production reader into the existing 64 MiB per-target source budget, without
+an aggregate stdout string. Two resident function indexes each derive from at
+most 2 MiB diagnostic or 8 MiB native wire source. Compressed native graphs admit at most 32 MiB decoded
+JSON plus independent row/text/relationship bounds. One decoded Evidence text view
+up to 32 MiB is also retained per lease; these source bounds are not parsed-heap
+size guarantees. Sources are
+content-digested and retained until close; explicit evaluator copies survive
+close. Capacity failures are explicit, not clipped facts. Leases and snapshot
+handles prevent cross-session joins.
+
+The current experimental MCP profile also caps encoded tool-result bodies at
+1 MiB, including text escaping and metadata; JSON-RPC/client framing is separate.
+`reference.transport_limits` advertises this policy in both modes. The QuickJS
+bridge remains 2 MiB. CLI/SDK transports have their own bounds; SDK full selected
+string values remain available. Prefer `strings({query,fields:[]})` for metadata.
+
+Invocation context and observed source IDs are additional bounded receipt
+metadata; the script payload bound is not a 32 KiB whole-MCP-wire limit. A real
+MCP probe found that a 40,000-byte guest exception bypassed that payload policy
+and produced a 40,183-byte response. Oversized errors now return explicit
+`output_budget` with omission metadata. Escaping expansion is checked too;
+ordinary smaller errors remain intact. `verify-executor.mjs` confirms real MCP
+delivery and continued access to source Evidence collected before the exception.
+It measures response bytes, not model tokens or an analysis speedup. Targeted JS
+tests at this stage totaled 42, alongside the separate real-provider and native-writer checks.
+
+The diagnostic SSA format still has incomplete CFG and phi predecessor coverage.
+The opt-in [native recovered IR experiment](native-engine.md) adds full recovered
+CFG edges, exact value/operand identities, phi incoming-edge bindings, selected
+`values`/`blocks` reads and derived control dependence. It requires an explicitly
+pinned patched engine; stock Kuna does not gain those capabilities from a wrapper.
+Runtime successors, memory aliases and machine-semantic equivalence remain
+unknown. Other providers are not yet wired to this experimental service.
+
+The initial [actual model comparison](trials.md) favors the focused traditional
+workflow. The seeded value-origin task has lower cumulative input and wall time
+through Code Mode, but initially exposes an IR-to-machine-path error. The revised
+trial correctly explains that machine path with lower observed task costs;
+broader claims still require more than this single seeded task.
+
+The large SQLite VM diagnostic task also completes when its native graph exceeds
+capacity. Atomic direct beats Code Mode on cumulative input and wall time in
+that sample, and a traditional reused-project run is fastest. The actual CLI
+client already exposes JavaScript dispatch in every lane, regardless of requested
+feature flags. MCP request counts therefore do not establish fewer model rounds;
+the ledger now records actual model responses and client dispatch/wait calls.
+
+`instructions` reads selected machine byte/decode windows through the same
+owner. Recovered operations use `origin_address` and blocks `origin_start`;
+these locations cannot be substituted for machine branch destinations. The
+value-origin trial demonstrates why this boundary matters. The experiment
+now has nineteen fact methods, still behind the same four-tool Code Mode
+catalog.
+
+`calls` connects recovered call operations to native target specifications and
+separates argument SSA values from passing storage. `values(is_input:true)`
+selects retained callee inputs for exact storage comparisons. These candidate
+links preserve snapshot identities, missing specifications, unknown storage and
+runtime-binding limits. The [cross-function task and oracle](call-oracle.md)
+are fixed before its real-model trials; the graph wire format is version 3, with independent version-1 call facts.
+
+`references` now selects incoming exact-address references or outgoing
+instruction/function references, with native kind filtering, field selection and
+paging. Source Evidence plus `source_row` identifies an occurrence. Function
+applicability, excluded/unattributed rows, indirect targets and discovery stay
+explicit. `fields:[]` requests only the always-retained identity columns across
+projection contracts. The [reference question and independent oracle](reference-oracle.md)
+cover real SQLite VM aggregates and a machine call omitted from optimized IR.
+
+`bytes` reads explicit virtual-address ranges as native loaded-image hex without
+decoding them as instructions. Batched reads preserve short reads and individual
+failures, with 64 KiB aggregate selected-byte capacity to bound hex/bridge growth.
+Complete hexdumps remain in Evidence. The original-file-offset mapping and live
+runtime memory remain unknown. This closes a direct byte-reading contract gap
+for data tables; it does not establish arbitrary memory-alias analysis.
+
+`functions` provides selected name/alias/entry reads. Native snapshots report
+code and recovered-IR facets separately, preserving readable code when graph
+extraction is unavailable. Real capacity and cold/warm MCP checks are documented
+in [native-engine.md](native-engine.md). Whole-model costs and unequal-depth
+comparisons remain separate in the trial report.
+
+The corrected SQLite comparison reaches the formatter implementation in all
+three interfaces. Code Mode uses fewer calls than atomic direct in that sample;
+a traditional run reusing its persistent whole-project cache is faster than
+Code Mode's fresh lease. Cache state, completed-answer coverage and actual
+uncached tokens must therefore accompany any cost comparison.
+
+SDK views share immutable parsed inventories with their owner. A real SDK probe
+initially changed a returned string and made the next query disappear under the
+same Evidence ID. Freezing at the cache boundary fixes that producing rule,
+without copying or parsing the entire inventory for each read. `verify-sdk.mjs`
+checks the real provider's string/metadata/function views and complete retained
+source digest. The fixed probe passes under the bounded runner (1.328 seconds,
+1.144 family CPU seconds, 110.6 MiB kernel family peak, zero OOM kills and verified
+payload cleanup); it is a correctness check, not a model-cost measurement.
+
+Encoded size is another real coverage boundary: two SQLite functions initially
+lose even their C because pretty JSON exceeds transport capacity. The native
+patch now uses bounded compact serialization and a graph-only failure when
+needed. Parser's full graph fits; Pragma retains identical C with an explicit
+missing graph. The 8 MiB bound remains. See the exact sizes, rebuilt engine digest
+and verification scope in [native-engine.md](native-engine.md).
+
+Completion requires actual model Code Mode use, independently checked task
+answers, shared atomic/direct/Code Mode semantics, needed relation coverage,
+failure/cancellation/identity tests, and equivalent completed-task measurements
+including discovery/retries, actual model usage, cold/warm analysis, CPU and
+process-family peak memory. Negative cases such as the small SQLite function
+must remain in the comparison.
+
+The outgoing-reference real-model pair now completes with identical required
+facts and explicit coverage limits. In its single sample, Code Mode uses 264,680
+cumulative input / 93.837 seconds versus direct's 285,086 / 106.183. The shared
+CLI/API also verifies the VM aggregates on unpatched stock Kuna 1.833. These are
+scoped positive results alongside the earlier mixed adapter comparisons, not
+proof of general superiority. Details and retained failed/partial attempts are
+in [trials.md](trials.md).
+
+Recovered calls and their boundary values now survive full-graph capacity
+failure. The real VM capture preserves 416 call operations and 1,294 boundary
+values while its graph remains unavailable. Values clearly state their partial
+scope; definition IDs do not imply readable defining operations. See the
+[boundary question and oracle](boundary-oracle.md) and its completed real-model
+pair in [trials.md](trials.md). Both answers pass, using one VM capture each.
+Code Mode's single-sample latency is lower, with mixed context costs; broader
+efficiency remains unproven. The focused JS suite at that stage passes 49 tests.
+
+Available snapshot call facets now include `by_opcode` known/unknown-target
+counts and their own coverage. The owner derives them once from the same
+validated immutable calls used by selected reads, including dead operations;
+target knowledge is independent of opcode. Empty available facets report zeros,
+while unavailable facets omit counts. This small aggregate addresses an observed
+cost in the real boundary pair: paging the entire call set just to count it.
+Both subsequent real-model answers satisfy the unchanged question/oracle without
+that paging. In the new sample direct is faster and lower on cumulative/uncached
+input than Code Mode, reversing the preceding latency ordering. Whole-task
+effects remain mixed; see [the complete results](trials.md). This aggregate is a
+shared fact-layer improvement, available to either adapter.
+
+The shared owner also checks the native cleanup `Result` before releasing its
+lease or clearing retained state. A tagged cleanup failure now stays retryable;
+MCP errors retain the lease context and reported resources. The real SDK
+failure-injection verifier first reproduces the old false success, then verifies
+both close and target replacement retain the staged file/owner until a successful
+retry. Both public MCP adapters preserve that error and retry successfully.
+These use an injected tagged failure, not an observed engine cleanup incident;
+native reads and subsequent cleanup use the real provider. See the recorded
+scope and resource receipts in [native-engine.md](native-engine.md).
+
+A [subsequent diagnostic probe](projection-experiment.md) measures the VM's full
+17 MB recovered graph and much smaller selected definition neighborhoods. It
+supports trying a bounded operation/value facet, while preserving unresolved
+definitions and unavailable CFG. The following implementation now makes that
+facet callable; the original diagnostic remains separate from public results.
+
+`snapshot.facets.operations` distinguishes a complete recovered graph from a
+bounded call-rooted definition projection. `operations`, `values`, selected
+definition/use `relations` and `slice` share the same parsed operation owner in
+either case. Projection coverage preserves unexpanded definition counts and
+selected slice frontier reasons; CFG/controller reads remain unavailable.
+Native operation reads retain `is_dead` and literal operand/value identities.
+Coverage returns compact counts and bounded issue text, with complete native
+details retained in Evidence. [The new question/oracle](projection-oracle.md)
+are fixed before real-model trials of the PHI format alternatives.
+
+Both first PHI-format model answers pass the full oracle using one VM analysis
+and a six-operation selected trace, with the global graph/use limits intact.
+The trace reveals two format sources at each shared call, verified against byte
+and machine evidence. [Costs and source review](trials.md) also record a direct
+documentation-lookup miss; named discovery needs fixing before rerunning the
+same task. No general adapter speedup follows from that first pair.
+
+Named reference lookup now accepts canonical IDs or exact displayed names,
+including space/comma-separated lists. One presentation map supplies direct
+registration and documentation names; unmatched terms remain explicit. Selected
+schemas come from named contracts, use input semantics (defaulted fields stay
+optional), and are cached immutably by Zod schema identity for the process.
+Validation stays in the API registry; documentation has its own module. Both
+actual MCP catalogs and all fourteen reference schemas validate. The unchanged
+PHI question/oracle were rerun: both answers pass again, but direct has a native
+timeout followed by a successful retry. Complete costs and the unknown timeout
+cause remain in [trials.md](trials.md); this does not isolate an adapter speedup.
+
+The next observed atom boundary is a wide PHI. One real VM operation has 156
+inputs; its old default single-node slice is about 44 KB and exceeds the guest's
+32 KiB result budget. Native operation/slice defaults now return opcode, output
+and exact input/definition/constant counts. Explicit detailed fields still work.
+`relations({kind:"operands",seeds:[id],input_indices:[0,105,155]})` reads selected
+slots; omitting the selector pages all slots. Each slot retains value/definition
+and phi predecessor/edge identity, including null values and definition-free
+constants/inputs. Counts concern recovered facts, not source function arity.
+
+Full and projected native operations use the same owner. Relationship paging
+counts existing groups before materializing only the requested page; identity
+reads deduplicate requested IDs in caller order. Diagnostic SSA explicitly lacks
+native operand relations. The discriminated relation schema advertises the same
+seed types and selector applicability enforced at runtime. The fourteen-method
+API and both adapters remain shared; no new engine or output-budget increase is
+needed. The [seeded wide-operand task/oracle](operands-oracle.md) is separate from
+the earlier PHI-format question and is pinned before model trials.
+
+Both actual wide-operand model answers now pass that fixed oracle, including
+distinct edges sharing a value and absent-slot versus unretained-seed semantics.
+Each performs one native analysis and reads only selected slots, distinct values
+and their immediate definitions. Code Mode takes 95.699 seconds versus direct's
+91.817, with nearly equal cumulative input and lower uncached input. Its four
+discovery lookups prevent fewer MCP requests from becoming fewer model responses.
+These [mixed costs](trials.md#selected-wide-phi-input-relationships) validate the
+fact boundary while leaving broad efficiency unproven. The current shared JS
+suite passes 57 tests; the Python cost-ledger suite passes three.
+
+Discovery now also offers `reference({view:"index"})`: the complete fourteen
+method names and descriptions, without schemas or return contracts. Follow with
+`view:"contracts"` and exact names for only the needed inputs. The default
+contract view and named/topic lookup stay compatible. Both views use the same
+registry and presentation map; index access never constructs unrequested schemas.
+The index describes declared methods, while `snapshot` remains the live coverage
+authority. This addresses observed blind discovery without inventing aliases or
+changing analysis facts; its whole-task effect must be measured on the unchanged
+wide-operand question.
+
+The identical question now completes correctly through both indexed adapters.
+Code Mode uses the intended index plus one named lookup; discovery drops from
+four calls to two, without changing the seven fact reads. The new pair takes
+about 98.8 seconds each; cumulative input favors direct, uncached input favors
+Code Mode. All four wide-operand answers pass, with no retry or OOM. Costs remain
+mixed. A selected-slot read still incurs whole-function native decompilation on
+a fresh lease; phase profiling is the next computation question, separate from
+the now finer fact/query boundary.
+
+The [native phase study](native-compute-study.md) now measures the VM drive at
+about 34 seconds, C rendering at 0.22 seconds and projection at 0.03 seconds.

+# AArch64 import entries and return coverage
+
+Two independent producer defects are corrected: BTI import-entry identity and
+false no-return promotion that erased a post-warning path. A fresh three-way
+model run passes the selected task oracle with all interfaces. Direct atomic
+reads use less cumulative and uncached input and finish sooner than Code Mode
+in this sample, despite more MCP requests. Correct primitive facts are useful;
+the extra Code Mode layer does not automatically improve a completed task.
+
+This continues the [three-way warning investigation](aarch64-xref-study.md),
+where all three interfaces encountered the same dropped post-warning path.

+## PLT entry checkpoint
+
+The actual Debian arm64 SSH fixture remains SHA-256
+`de352e4ace7028d9816fd0ee9d22936bc1b5622c400d5b0b7df660df3426b068`,
+1,051,744 bytes, extracted and never executed. The independent
+[machine verifier](verify-aarch64-machine.py) checks the warning epilogue's
+restored LR/SP, tail branch `0x25858 → 0xbad0`, BTI at that entry, ADRP at
+`0xbad4`, loaded GOT slot `0x10f390`, and its `free@GLIBC_2.17` JUMP_SLOT
+relocation. GNU objdump's neighbouring synthetic PLT label is not authoritative
+symbol identity. Actual runtime binding, pointer authentication and path
+feasibility remain unknown.
+
+The old loader recognizes an ADRP/LDR pair and names the ADRP address. The
+resulting inventory splits `sub_bad0` (4 bytes) from `free` at `0xbad4` (20).
+The corrected owner recognizes the complete standard veneer, optional immediate
+BTI c prefix and optional AUTIA1716. It uses the ADRP's own PC and exact
+relocation slot, without assuming a PLT stride. Complete load/add/branch
+agreement is required before consuming a relocation. Truncated/corrupt sequences,
+ordinary preceding instructions, missing slots, misalignment and overflowing
+instruction ranges cannot manufacture an entry.
+
+The AArch64 decoder and its tests move into `loader/elf_plt/aarch64.rs`;
+section and PT_DYNAMIC paths call that single owner. The parent still owns GOT
+name correlation and deduplication. These supported sequences follow Arm's
+[System V ABI examples](https://github.com/ARM-software/abi-aa/blob/main/sysvabi64/sysvabi64.rst#sample-plt-sequences).

+All 13 PLT decoder tests then passed, including seven AArch64 groups and the

+`free` at `0xbad0` and `_exit` at `0xbdd0`; their former ADRP-body entries disappear.
+The warning's recovered tail call names `free`. The real native CLI
+[loader verifier](verify-aarch64-plt.py) checks both the original ELF section
+path and PT_DYNAMIC fallback using a separately hashed derived copy with only
+ELF section-header coordinates zeroed. Both produce the corrected entries.
+Neither input is executed. Both patch application directions pass.

+All listed scopes verify payload cleanup, observed OOM 0, one CPU and the existing

+SDK sessions use fresh retained-evidence stores; OS cache state is uncontrolled.
+The single equivalent SDK pair does not establish a performance improvement.
+No new model/token measurement or broad repository typecheck is claimed here.
+
+The PLT-only correction **does not** restore the caller's strict diagnostic:
+its recovered call facet still omits `0x2854c`, and C still marks the warning
+call at `0x2841c` no-return. This controlled result separates the import-entry
+defect from the no-return defect. The discovered-no-return pass has a weaker
+terminal-call promotion than the existing propagation walk: it observes a
+terminal call somewhere and absence of RET, without rejecting an escaping tail
+transfer to possibly returning code. Causality and the structural correction
+require their own checks; the entry fix alone is not claimed to solve it.
+
+## No-return ownership checkpoint
+
+With the PLT-only engine unchanged, disabling only `noreturn_disc` restores the
+caller call at `0x2854c` and removes the false no-return annotation from the
+warning call at `0x2841c`. That native CLI counterfactual takes 5.052 s wall,
+4.813974 s local family CPU, 175.6 MiB kernel family peak, with verified cleanup
+and observed OOM 0. It isolates the discovered pass; it is not the final fix or
+the configuration supplied to model evaluators.
+
+The discovered pass's duplicate promotion scanned a whole function span for
+any terminal call and no RET. An alternative tail transfer to a returning
+import therefore failed to protect the caller's continuation. The correction
+removes that interpretation and shares the propagation pass's conservative
+reachable-path walk. Known terminal transfers stop a path; returning tails,
+missing successors, unresolved indirect jumps and escaping branches cannot
+prove the whole function no-return. A dead, unreachable RET no longer prevents
+legitimate promotion. Existing call-site threshold and strict-successor options
+remain, but an absent local successor contributes no new vote: it is compatible
+with a returning tail call. The inspected
+[Ghidra analyzer](https://github.com/NationalSecurityAgency/ghidra/blob/master/Ghidra/Features/Base/src/main/java/ghidra/app/plugin/core/analysis/FindNoReturnFunctionsAnalyzer.java)
+also skips calls without fall-through when looking for new indicators; this is
+source comparison, not a real-Ghidra runtime verification.
+
+The shared entry first checks for any terminal-transfer candidate before
+allocating a body map or visiting its CFG. That necessary-condition check also
+applies to the existing propagation consumer. Terminal sets still grow during
+the bounded fixpoint, so false results are not cached across changing sets.
+There is no added long-lived graph cache or duplicate adapter interpretation.
+
+Five new semantic test groups cover the fatal/returning-tail alternative,
+four different unknown exits, genuine terminal paths with a dead RET, a
+transitive wrapper fixpoint, and missing versus positively identified
+successors. Against the old rule, four groups fail and the wrapper group passes
+(the two pre-existing smoke tests also pass). After the correction, all 39
+no-return-related tests pass, including those groups. Expected-failure run:
+68.371 s wall / 68.147478 s CPU / 889.2 MiB peak. Passing run including compile:
+73.808 s / 72.914925 s / 892.6 MiB. Both have verified cleanup and observed OOM 0.
+An earlier syntax-error attempt is not counted as a semantic regression run.
+
+The final overlay SHA-256 is
+`597b5236c42b214b88da39afe0f2b2b1cd7c5ff82e512e91d6a3249bfef565f1`;
+the immutable engine SHA-256 is
+`0969be0c9c3ace9357acce1f802f12e8595bc57445da32937933de543ca77672`.
+Forward-index and reverse-worktree application checks pass. The public
+[SDK verifier](verify-aarch64-returns.mjs) now finds the strict call at
+`0x2854c`, removes the false warning-call annotation, retains the genuine fatal
+call annotation, verifies canonical import ownership and byte identity, hashes
+all retained sources, and checks complete C/source fidelity and warm reuse.
+Warm captures retain identical handles/facts: warning 0.770 ms / 0.000797 CPU s;
+caller 0.702 ms / 0.000761 CPU s. Cold captures take 2033.6 / 5857.3 ms and
+2.023671 / 5.835244 CPU s respectively. These are lease cache observations, not
+OS-cold or model-task measurements.

+The unique per-response usage sums match each runner total. Cache writes are
+zero. All three runs preserve runtime/engine/target fingerprints, close the
+target, remove their isolated profiles, verify payload cleanup and observe OOM 0. Whole-scope final counters remain unavailable; family CPU/memory use verified
+payload-exit observations. Memory includes charged file cache, not just RSS.
+Remote compute, resolved service model build, OS cache state and host contention
+are unmeasured. Fresh local profiles do not imply cold OS or remote model caches.
+
+Code Mode executes its 23 fact calls inside eight `execute_javascript` requests;
+Direct issues 22 `facts_*` requests. Each mode retains the same two complete
+native function documents, verified equal, including restored strict call
+`0x2854c`, the selected pointer bindings, and the warning's named `free` tail.
+Code Mode requests three snapshots but captures only two distinct sources; a
+repeat uses the existing lease cache. Different queries/field selections and
+model response counts are part of the measured workflows, not equal instruction
+traces. Both modes, and traditional, also have the same client-side JavaScript
+executor available. This compares MCP/API surfaces, not JavaScript versus its
+absence.
+
+The traditional run first passes xref instruction addresses `0x25750` and
+`0x2853c` to an exact-entry analysis operation; both are correctly rejected. It
+recovers with `list_procedures`. Traditional `xrefs` normalizes these results to
+address strings; the atomic response also supplies native owning-function
+facts. Those navigation differences and retries are counted. Its two successful
+function dossiers share the same ready project-export key
+`dbfd828b95d9c1a2981707728a9e31b4c38688162e851a904c3808fd911c79eb`.
+Higher CPU is not evidence of a broken project cache. Traditional project export
+and per-function atomic export remain different native analysis profiles; the
+comparison does not isolate transport or schema cost from analysis scope.
+
+All complete answers were read and passed agent review against the frozen
+question, independent file/GNU oracle, selected additional GNU checks and their
+actual delivered Evidence. Each identifies both functions, proves the selected
+pointer transfer and first helper target, verifies format formation/passing,
+the four-byte test and actual zero/nonzero successors, conditional cleanup
+return, and the necessary runtime/logging/alias limitations. This is selected
+task correctness, not human readiness or general analysis completeness.
+
+Every cited source is verified: 11 traditional, 14 Code Mode and 14 Direct IDs.
+Traditional projected views correctly have their own provider and null engine
+profile; their explicit parent-Evidence links trace to the pinned engine. An
+initial audit incorrectly required a native engine profile on each projection;
+the corrected audit follows that provenance chain and passes. Atomic retained
+source byte counts/digests, target/engine contexts, selected native call/value
+bindings, restored strict call and complete selected-function equality pass.

+# Composable AArch64 address references
+
+The AArch64 OpenSSH check exposed a real completeness gap before another model
+comparison: both warning strings were present, but Kuna returned zero incoming
+references for either. Native observations had unknown discovery coverage;
+zero was not proof that the strings were unused. Independent GNU decoding
+showed ADRP plus ADD at `0x2574c/0x25750` and `0x28534/0x2853c`.
+
+The query scanner read one instruction's p-code at a time. The existing ARM
+pool-displacement tracker supplied the relevant bounded value-flow owner, but
+did not carry AArch64 page bases. The experiment extends that owner rather than
+introducing another interpreter or postprocessing disassembly text. SLEIGH's
+mnemonic licenses ADRP, and its exact constant COPY supplies the coordinate;
+COPY/ADD/SUB then propagate the value. Machine operand text and hardcoded
+register-offset tables are not reparsed. Possible page copies alone, such as
+ordinary MOV-immediate instructions, do not establish PC provenance.
+
+The same calculation produces Data for materialized register addresses, or
+Read/Write for a LOAD/STORE through a composed default-data-space byte address.
+The accessed cell is identified; its mutable/GOT contents are not propagated
+as a live value. This also covers the selected GOT slot, which an intermediate
+address-only fix still missed. Space-selector constants and stored values are
+not mistaken for access pointers.
+
+The directly related refactor renames the former private pool-only module to
+`kuna_pc_relative`, moves its tests out of the implementation and retains one
+value lookup for arithmetic and memory accesses. Keys preserve native space
+identity, offset and width. Partial overwrites invalidate overlaps; copies can
+carry a known value into a different register. Calls/jumps/returns stop carry,
+instruction-local predicates do not execute both arms sequentially, a pool
+load overwritten later in the same instruction cannot seed a stale value,
+unsupported widths remain unknown and interval checks include the final u64
+byte without overflow. Empty/failed assembly rendering cannot license ADRP.
+
+State remains function-local, follows fall-through addresses and keeps the
+existing eight-hop/eight-value bounds. It is not a complete fixed-point,
+cross-call, alias, runtime-value or feasible-path analysis. Unknown discovery
+and indirect-target coverage remain explicit through the shared parser and
+SDK/CLI/MCP views. Both experimental adapters and the traditional Kuna provider
+consume the corrected native producer; no special advantage is injected into
+one evaluator lane. Stock Kuna is not silently upgraded.

+
+The 17 PC-relative tests include the retained pool-displacement cases and new
+page/copy/space/width/clobber/predicate/access cases; they are included in the
+125 Listing tests, not additional independent executions. An intermediate run
+passed 16/17: its obsolete assertion expected no reference when a composed
+temporary was dereferenced. The intended extension now identifies that actual
+cell Read while retaining the negative assertion against a register address-taken
+claim. The test was updated to require exactly that stronger typed outcome.
+All failed/intermediate receipts remain local; they are not model attempts.

+The AArch64 two-address reference batch takes 3,548.3 ms wall / 3.535213 CPU s
+on a fresh lease, versus 1.54 ms / 0.001539 s for the same-lease repeat. This
+shows retained-source reuse, not faster native discovery. Old engine c48ad957
+returned incorrect zero results; its costs are not an equivalent completed-task
+performance baseline for those new facts.
+
+A separate equivalent x86 task requests the same three exact-address reference
+sets before/after. Every normalized fact and coverage field agrees (counts
+1/1/2), using fresh leases/private caches. Its old/new cold phase is
+4,028.3/4,082.2 ms wall and 3.993216/4.031850 CPU s; warm is 3.30/2.38 ms.
+Whole-run wall is 4.852/4.852 s, CPU 4.554857/4.580338 s, peak 155.3/157.4 MiB.
+This single lookup repeat shows no material observed regression for that case;
+it is not a model-token measurement or a general speed guarantee. OS/cache and
+host variation remain uncontrolled.
+
+## Frozen model task
+
+The [question](aarch64-warning-question.txt) and [oracle](aarch64-warning-oracle.md)
+ask the same behavior-level warning/pointer/guard/cleanup question through
+three complete interfaces. Native SSA identities are optional. Traditional
+preflight supplies the same strings, actual references, both C/assembly dossiers,
+and recovered static `dat_1104f8`, with target/engine digests verified. Its first
+dossier costs 95.291 s waiting for whole-program export; later assembly/dossier
+reads reuse that cache. Atomic selected-native profiles differ, so the planned
+comparison is a full workflow comparison, not a dispatch-only ablation.
+
+The runtime/question/oracle are frozen at
+`5eede35c978c76ff9215443ed0a0d5980bfbdfe1`. Execution order is traditional →
+Code Mode → direct. All request gpt-6.1-sol/high via Codex 0.161.0, with fresh
+isolated profiles/private caches and the same task. Both atomic catalogs are
+complete (22/4 tools); the traditional set contains every declared Kuna native
+operation and session/views (16 tools). Each client actually has JavaScript
+dispatch. This compares MCP workflows inside that common client surface.
+
+All three complete answers pass agent review against the frozen oracle. They
+identify both owners, the X27→X0 pointer/helper transfer, banner ADRP/ADD into
+X6, four-byte field/CBZ successors, static versus live pointer knowledge,
+cleanup/low return bits, Evidence/target identities, unknowns and close. The
+traditional answer uses native C recovery plus machine addressing for the static
+global; both atomic answers also read the selected loaded-image pointer bytes.
+No native-only representation is required to pass.
+
+Separate scripted checks verify all seven traditional, fifteen Code and fourteen
+Direct cited sources against delivered responses/traces and target/engine
+identities. Atomic retained source hashes/lengths agree; complete selected native
+function documents are identical between the two atomic lanes. Selected native
+argument/value/passing tuples and the PHI/input distinction match the delivered
+graphs/call facets. The independent ELF/GNU oracle checks the machine facts.
+Supplementary GNU checks corroborate the traditional answer's added logging
+wrapper call at `0x5ae6c → 0x5abb0`, with X6 unchanged. Source/fidelity checks
+are separate from agent review of the entire natural-language answers; neither
+constitutes human readiness or global machine-equivalence verification.

+Both traditional rejections are instruction-interior addresses passed to exact
+procedure lookup. The inventory was available, the model used it and completed;

+report the same ready project-export key, so the observation does not establish
+a broken project cache. Its extra logging-wrapper investigations and native

+charged; failed/intermediate development checks are separate from model trials.
+
+Code uses 24.7% less cumulative input and less wall/CPU time than Direct in
+this pair, but more peak memory. Compared with traditional it uses 43.0% less
+cumulative input and less wall/CPU/memory, but **23.9% more uncached input** and

+Mode advantage, a price claim or broad complex-software superiority.
+
+Unique per-response usage sums match the task totals. All target, engine and

+## Remaining native identity/control-flow question
+
+All answers detect the recovered caller's no-return treatment of the warning
+call and use machine instructions for the requested conditional post-call path.
+The recovered call facet omits the strict call. Complete recovered-graph coverage
+therefore does not establish a complete machine graph or a correct no-return
+inference. This is a concrete remaining backend/identity investigation.
+
+Supplementary static observations identify a suspicious boundary: the warning
+epilogue restores LR/SP and branches at `0x25858` to `0xbad0`. That address
+starts with BTI, followed by ADRP at `0xbad4` and a slot load at `0xbad8` from
+`0x10f390`. ELF `R_AARCH64_JUMP_SLOT` names that slot `free@GLIBC_2.17`.
+The native inventory instead exposes `sub_bad0` with size bound 4 and `free`
+at `0xbad4` with bound 20. GNU's synthetic PLT label at `0xbad0` says closedir,
+which the actual slot relocation contradicts; it must not be used as symbol
+identity. Whether the native BTI/veneer split causes the no-return propagation
+still needs a producing-boundary investigation and regression proof. No such

+# Calls and values surviving full-graph capacity
+
+The question is `sqlite-boundary-question.txt`. Fix it and this acceptance oracle
+before either real-model run. Both lanes use the same complete fourteen-method
+API, preserved engine, model/effort request, common guidance and resource limits.
+This task requires VM decompilation once per fresh lease; it is different work
+from the earlier shallow-reference question. Do not compare their task times as
+an adapter speedup. Actual client JavaScript dispatch is available in both lanes.
+
+Artifact: Debian `libsqlite3-0:amd64` version `3.40.1-2+deb12u2`,
+`libsqlite3.so.0.8.6`, SHA-256
+`2e6eef9a727f081f0d453b4e5e6cbd8b9ef8b6f86cbf7681cbad444d3b0b55c8`.
+The selected VM implementation entry is `0xea6d0`, not its same-name PLT entry.
+
+Pre-model public MCP capture with the new exporter establishes:
+
+- Code is available. Full graph is unavailable with `atomic operation capacity
+  exceeded`. Calls remain available: 416 retained block-member operations,
+  consisting of 395 CALL and 21 CALLIND. The 395 direct targets are known, all
+  21 indirect targets remain unknown. Call-boundary values are available (1,294),
+  covering targets, arguments and outputs only, with 21,349 operations scanned
+  over 1,229 recovered blocks. These do not supply a complete definition/use graph.
+- At `0xf115c`, recovered call ID `0xf115c:6a84` targets `ram:0x296c0`.
+  Input zero is `v1000118d6`, `fspec:0x102f4`, annotation true, width 8.
+  Three recovered inputs use passing storage `register:0x38/8`, `0x30/8`,
+  `0x10/8` (RDI, RSI, RDX in this verified x86-64 lane).
+- At `0xf238b`, call ID `0xf238b:7130` has the same resolved target.
+  Input zero is `v100012a80`, `fspec:0x1030c`, annotation true, width 8.
+  Two recovered inputs use passing storage `register:0x38/8`, `0x30/8`.
+- Both first arguments are the same snapshot-local SSA value `v30000004b`,
+  `register:0x38/8`, `is_input:true`, definition null. Other retained argument
+  values have defining operation IDs outside this boundary view. Exact SSA
+  identity is supported; source parameter ordinals and general aliases are not.
+
+Independent GNU objdump decoding from the exported VM entry verifies the two
+machine CALL targets and register setup. The earlier complete direct-call pair
+oracle contains both. Of the 396 physical direct immediate calls, the only one
+absent from the recovered 395 is `0xf2493 -> 0x29370` (stack check failure).
+The question does not require rediscovering this extra call; the recovered-call
+count must not be claimed as complete machine/runtime coverage.
+
+Required final facts: correct selected entry and facet availability/scope; both
+call-count groups and target-unknown distinction; both resolved targets separated
+from annotation offsets; argument slots/locations; shared first-input identity;
+selected machine checks; explicit unreadable definition/use and alias/runtime
+limits; real Evidence and subject digest. Do not require the model to report
+every additional native metadata counter. Check that its API source arguments
+show only one VM analysis and all relevant reads reuse its snapshot/Evidence.
+
+Raw public verification is retained as `facets-v3-mcp.json` and its Evidence
+directory under `.cache/atomic-codemode/`. The ordinary VM record (C, mappings,
+variables and other ordinary metadata) equals the prior captured engine output.
+The independent oracle and precomputed answer are absent from the model workspace.

+# Frozen shared-byte model task
+
+Use the unchanged `native-string-query-question.txt` and all exact target/string/
+byte facts in `native-string-query-oracle.md`. The target digest and 4+1 string
+objects are unchanged. This phase's pinned engine is `bce4dc97fda99a028aca6b2b40a0a593c87b5224ac9e03221a69313faba2d3e8`,
+with both `REA_ATOMIC_NATIVE_STRING_QUERY=1` and `REA_ATOMIC_NATIVE_BYTE_BATCH=1`.
+The earlier oracle's engine digest describes its earlier frozen runtime only.
+
+Both query reports remain distinct and each covers 602,544 candidates. A native
+byte report may now contain several requested windows with one shared source ID;
+source_row identifies a native window row, not the caller's ordinal after reuse.
+Repeated or reordered ranges may refer to the same original row. Fewer distinct
+byte Evidence IDs are valid when the cited source actually covers every claimed
+window. Counts/hex and provenance must remain exact. Focused covering reads are
+still allowed. Do not require ten commands or unique source IDs per window.
+
+Grade complete original answers, all cited source hashes/contexts, raw byte
+payloads and actual source-window reads. Keep failed calls and all costs, with no
+answer repair or winning retry. Direct and Code Mode use the same 19 methods,
+question, model/reasoning, static authority and resource controls; actual Code
+Mode MCP execution must be observed. Report cumulative tokens, cached/uncached
+input, output/reasoning, schemas/help/calls/retries, wall, local CPU and kernel
+family peak. Actual clients have common JavaScript dispatch. Remote costs and
+resolved model builds are unmeasured. One run per lane does not establish broad
+RE superiority; historical model results use a different pinned runtime, while
+the SDK acquisition-toggle comparison uses the same current engine and code.

+# Shared native byte reads: checkpoint
+
+The user cleared the active goal after implementation and real preflight.
+Work stopped before new model trials. No PR or merge into main is requested.
+Main was refreshed to `5112fe07a` in `2dc3820b6`. LeanToken returned not_indexed
+for this experimental path; scoped native reads were used instead.
+
+Opt in with `REA_ATOMIC_NATIVE_BYTE_BATCH=1` and an exact experimental native
+engine pin. Unset/0 preserves single-window acquisition. The 19 shared methods,
+22 Direct tools and four Code Mode tools are unchanged. The byte batch reads
+only selected static loaded-image ranges; no target execution or modification.
+
+`disassemble/kuna_batch.rs` shares one existing ConsoleProgram load, range
+resolution, mapped-end clipping and data renderer across at most 16 windows /
+64 KiB selected bytes. It rejects ignored options and bounds encoded output
+against the existing 8 MiB capture ceiling. Each native row retains its exact
+request, ordinal and success or window_unavailable error. Global load or report
+encoding failure fails explicitly. The old read path can initialize again when
+a bounded anonymous region lacks a name; this is source-derived reasoning, not
+a measured count of internal translator initialization.
+
+`NativeByteBatchReads` caches validated exact address/length facts for this target
+lease, deduplicates missing ranges, batches only missing work and preserves caller
+order. Source + source_row identify a window in retained raw Evidence; duplicates
+or reordered calls can share that row. Partial reads remain partial. Successful
+siblings survive bad per-row data; global failures preserve cached facts. Transient
+capture failures are not cached here. Close clears the cache. Its retained entries
+are bounded by source admission (128 sources times at most 16 windows); no global
+cache or live-memory freshness claim is added.
+
+Old and new byte reports use one normalization owner. Exact JSON numeric tokens
+preserve u64 aliases and reject rounded fractional counters, with shared KunaJson
+support; alias disagreements fail instead of publishing contradictory facts.
+Original-file mapping and runtime memory remain unknown/not-observed.
+
+## Executed evidence
+
+- Native disassemble tests: 15 passed, including the two new protocol/budget tests.
+- Runtime build passed; final experimental JS tests: 128 passed.
+- Kuna reference files/ranges boundary tests: 27 passed.
+- Changed-file lint/format, module boundaries, affected-source typecheck and
+  converted actual MCP schema/catalog checks passed.
+- Real SDK, Direct and Code Mode LLVM checks passed all prior five literal-query
+  goldens, paging, projection, exact ten independent byte windows and 13 complete
+  retained source hashes per lane.
+- Both actual MCP adapters passed SQLite mixed success/error, short reads,
+  repeated exact windows and the full 64 KiB request.
+- Same-engine SDK comparison passed reordered/duplicate reuse, mixed cached/new
+  windows, all raw hashes and stale Evidence rejection after reopen.
+- Actual producer cancellation preserved cached facts in partial_observation,
+  allowed a fresh retry and completed owned cleanup. Target bytes were unchanged.
+
+The existing full repository typecheck memory refusal is not a pass. No full
+check:fast/check:pr, full native workspace gate, new architecture/provider parity,
+or new real-model result is claimed for this phase. Earlier model outcomes retain
+their own immutable revisions. The prepared byte-batch oracle is unexecuted by models.
+
+## Same-engine acquisition comparison
+
+Both runs use engine `bce4dc97fda99a028aca6b2b40a0a593c87b5224ac9e03221a69313faba2d3e8`, the same LLVM artifact and independent
+file oracle. Only acquisition is toggled between 0 and 1. Cold means a new lease,
+not dropped OS caches. These are single scripted observations with no model tokens.

+
+Cold ten-window retrieval drops from about 94.3 to 8.5 seconds. The warm sample
+is slower in the batch run; it is retained without claiming a warm speedup.
+New unseen windows still incur program initialization. The old workflow retains
+11 native sources for the completed task; batching retains two.

+Counters are verified at payload exit while the observer lives, not final whole-
+scope counters. Memory includes charged file cache. Heavy work was serial, one
+CPU, hard 4 GiB/no swap, with early stopping at 3 GiB (3.25 GiB for builds).
+The first compiled native version was replaced before real provider verification
+to distinguish request_address_hex from numeric native address aliases; original
+builds/logs remain. No failed run was relabeled as passing.

+# Cross-function context experiment: pinned question and oracle
+
+This is an experiment acceptance oracle, unavailable to the isolated model.
+The question is `sqlite-call-question.txt`. Fix this question and the required
+facts before launching either model lane. Both adapters expose the same complete
+fourteen-method fact API; Code Mode has four MCP tools, direct has seventeen.
+Use the same pinned engine, artifact, model request, reasoning effort, common
+envelope guidance, fresh target leases and resource limits. Do not change runtime
+sources or HEAD during the model batch. One sample per lane cannot establish a
+general advantage, and the client itself already offers JavaScript dispatch in
+both lanes. This comparison isolates the server calling adapter, not all forms of
+composition or a traditional provider workflow.
+
+The artifact is the local Debian ELF `libsqlite3.so.0.8.6`, SHA-256
+`2e6eef9a727f081f0d453b4e5e6cbd8b9ef8b6f86cbf7681cbad444d3b0b55c8`.
+Independent GNU objdump decoding from the function entries covers `0x64060`
+through `0x65400`; existing earlier captures independently pin the same flow.
+No target execution or source-code answer is used.
+
+Required facts for an equal completed answer:
+
+- Wrapper entry `0x65180`; direct machine CALL `0x65211` targets internal helper
+  `0x64060`. The recovered call operation has an fspec annotation as input zero;
+  that annotation's offset is not the target address.
+- Caller LEA `0x65201` passes post-prologue `RSP+0x20` in RDI. Structured passing
+  storage is `register:0x38`, width 8. The SSA argument and the callee's retained
+  input are separate snapshot-local identities; matching their storage supplies a
+  candidate connection. The direct machine transfer and pointer setup support
+  this particular connection. Do not globally infer source parameter ordinal,
+  alias completeness or runtime binding from a slot number or a name.
+- The helper preserves the input context pointer in RBP. Its 32-bit field at
+  context offset `0x30` is incremented at `0x64693`/`0x64696`/`0x64699` for an
+  opening parenthesis and decremented at `0x64c92` for a closing parenthesis.
+  The parser's token/branch context must support the parenthesis interpretation;
+  an ADD/SUB instruction alone does not identify the meaning of a field.
+- In the wrapper this is `[RSP+0x50]`, initialized to zero with the other context
+  tail fields. After helper return zero, LOAD `0x65268` and TEST/JZ
+  `0x65270`/`0x65272` check it. Zero skips the malformed block; nonzero frees the
+  expression at `0x65274`, clears its output pointer at `0x65279`, then reaches
+  the malformed diagnostic at `0x65281` through formatter call `0x65290`.
+- Return-code-one errors can also reach the malformed block, via
+  `0x65239`/`0x6523c`; return code 18 selects a separate depth-limit diagnostic
+  at `0x65330`. No demonstrated runtime-feasibility or full memory-alias claim.
+
+The producer verifier additionally checks two formatter call targets:
+`0x5f031 -> 0x2adc0` (free PLT) and `0x5f062 -> 0x27e50` (vmprintf PLT), whereas
+their input-zero fspec offsets are `0x10000`/`0x10001`. Resolving these PLT entries
+to runtime implementations is outside this task.
+
+Native producer fidelity is checked against previously retained captures of all
+three functions: C, ordinary metadata/line mappings, blocks, operations, values
+and coverage are identical. Only schema version and structured call records are
+added. Older sources used pretty JSON; their smaller/newer encoded sizes must
+not be attributed to the call exporter. The earlier compact-writer change is a
+separate experiment. Unsupported old schema graphs remain unavailable with valid
+C retained, rather than acquiring guessed call records.
+
+The first paired question runs at `01e5c5955` both explain the primary state flow
+correctly but omit the oracle's separate return-1/return-18 distinctions. Because
+the initial question did not explicitly enumerate those codes, the next round
+clarifies that requirement in `sqlite-call-question.txt` before either lane
+starts. The required facts and independent oracle stay unchanged. Earlier
+questions and costs remain pinned to their original commits; neither incomplete
+sample is counted as a full-oracle success.

+# Capability and comparison scope
+
+The experiment has nineteen fact methods behind a shared SDK/CLI owner, exposed
+as twenty-two direct MCP tools or four Code Mode tools. The structured IR/call/
+projection/switch facts require the explicitly pinned experimental Kuna patch;
+they are not capabilities added to stock Kuna or integrated REA by registration
+alone. Other providers are not wired to this experimental service.
+
+A fair completed-task comparison first needs sufficient facts on both paths,
+with a common correctness oracle. A complete universal RE interface is not
+established here. The selected-case question requires native row/edge identities,
+so it compares the two atomic adapters; no traditional-provider result for that
+question is invented. Earlier traditional comparisons retain their own questions,
+engine profiles and limitations in [the trial record](trials.md).

+The [string-span experiment](string-span-study.md) extends exact xrefs with
+batched incoming target-coordinate spans. It preserves all eleven selected
+SQLite data occurrences, including nine pooled suffix pointers, with individual
+endpoints/owners and raw source rows. Kuna already had aggregate string-span
+counts; the new occurrence query shares its sparse index. Range membership alone
+does not establish whole-string use, access overlap or runtime behavior.
+Three real models complete the pooled-string task. The traditional original
+inventory has a partial source audit after client truncation; atomic source
+captures are fully checked. Code Mode's cumulative input/time improve in this
+sample, while uncached input and memory exceed Direct. This remains task evidence,
+not provider parity or a stable adapter advantage.
+
+The useful grain so far is an identified object plus a relation with its exact
+qualifiers: an operand needs its slot and PHI binding; a case/out-edge pair needs
+both identities; an address needs its artifact/address space; an optimized
+operation needs its snapshot and representation. One small JSON row is not
+automatically one independently meaningful fact. Machine instructions and
+normalized operations also cannot substitute for each other.
+
+An identified object may still contain a huge field. The [capacity study](large-result-study.md)
+adds string metadata selection and pre-allocation transport accounting with
+recoverable source handles. Real SDK/MCP checks cover both escaping layers and
+in-program recovery. In the frozen model pair, Code Mode passes; Direct reports
+17-byte prefixes as 16 despite correct provider data. Preserve that failure;
+the pair cannot rank efficiency at matched correctness. Native capture still
+reads the complete bounded inventory, so small replies alone do not establish
+scalable producer work. The [streamed inventory experiment](streamed-inventory-study.md)
+restores FFmpeg queries over a 16.8 MB source with bounded files and the production
+parser. Both corrected real-model answers pass with all sources checked; setup
+failures remain in the ledger. Costs are mixed, and LLVM/Node still exceed the
+unchanged 64 MiB retained-source ceiling.
+
+Selection, projection, batching, paging and bounded traversal compose those
+facts. The analysis owner derives/validates relations; Code Mode selects and
+combines them. A query can be fine-grained even when its fresh native capture
+still computes a whole function. Same-lease reuse is measured separately from
+that work and does not establish a cross-session cache or native acceleration.
+
+The [control-query study](control-query-study.md) independently verifies all
+2,845 control-dependence triples in the real SQLite VM through both MCP adapters.
+Two real models also complete a two-level controller/SSA/path-witness task and
+distinguish alternative predicates from conjunction. Unknown CFG seeds are
+explicit, and the snapshot owner reuses a bounded lazy postdominator index.
+Code Mode has lower cumulative input but higher uncached input and runtime costs
+in that pair; precise derived facts do not imply a preferred calling adapter.
+
+The [OpenSSH value-query study](value-query-study.md) adds exact location lookup
+and inverse operand occurrences for value identities, including inputs/constants
+without definitions. It checks every retained selected version/use against the
+complete source graph; this is separate from machine-byte evidence and does not
+turn SSA occurrences into a memory-alias proof.
+
+The [stripped OpenSSH model comparison](ssh-warning-study.md) also verifies a
+common warning/caller/stack/guard question through the two atomic adapters and
+the traditional Kuna workflow. Exact machine facts suffice for the direct
+answer; extra SSA capture is not required by every RE question. The corrected
+traditional baseline has its complete declared native toolset. This expands
+the completed-task evidence while retaining the local scope and cost confounds.
+
+Memory alias dependencies, full machine-flow recovery, indirect runtime binding,
+feasible paths and nontermination remain unknown. The current evidence does
+not establish provider parity, broad complex-software superiority or a stable
+Code Mode cost advantage. The [wait repeat](client-wait-study.md) shows why fewer
+MCP requests or polls cannot replace correct answers and whole-task costs.
+
+The [path query](path-query-study.md) composes selected recovered edges into one
+paged witness under explicit exclusions, with zero-edge/not-found/unknown
+outcomes. Both real SQLite MCP lanes preserve every original edge field; complete
+native function fidelity is checked. This removes an observed graph-reading
+burden without establishing feasible runtime paths or an adapter cost advantage.
+
+The completed path-query pair answers the unchanged two-level task correctly in
+both actual models; each uses four path reads and three selected block reads,
+without a complete graph inventory in model context. Direct and Code Mode have
+similar wall time with mixed token/resource costs. Stock 1.833 explicitly rejects
+the unsupported path query while preserving readable Evidence/code in a real SDK
+check. These are scoped observations, not stock-provider parity or complete
+runtime reachability coverage.
+
+The [function-boundary study](function-boundary-study.md) adds independent native
+prototype entries/return descriptors. On real stripped SSH, prototype counts
+4/10 differ from raw input counts 3/44; both actual models preserve that distinction,
+all exact matches/missing tuples and the selected caller-to-callee/helper transfer.
+Call-passing storage is separate from the caller value's own coordinate. Native
+model labels and recovered entries do not prove original source arity/ABI.
+Complete old function fidelity is preserved except for the new facet. Actual
+old-native/stock checks return explicit unavailability with readable Evidence.
+The two completed model tasks have mixed token/time/resource costs; no stable
+Code Mode advantage or provider parity follows.
+
+The [storage study](storage-study.md) exposes native address-space descriptors
+and exact varnode_xref names without function decompilation. Width-qualified
+coordinates compose with prototype/value/passing-storage facts. Real x86-64
+and AArch64 OpenSSH catalog checks do not establish big-endian, alias, runtime
+or full provider parity coverage.
+
+Both real models complete the extended native storage/prototype/call task.
+Code Mode reduces cumulative/uncached input and wall time in that pair but uses
+more local CPU and more inner fact reads. The shared metadata capability is
+verified separately from this adapter observation; earlier mixed pairs remain.
+
+The [AArch64 reference study](aarch64-xref-study.md) corrects an observed native
+ADRP+ADD/LOAD/STORE gap through the shared PC-relative value owner. Real arm64
+SSH checks verify both warning owners, callers, selected machine words and
+77 GOT-slot reads. Coverage stays bounded and does not propagate live GOT
+contents. Traditional C/assembly preflight can answer the same new behavior-level
+question, avoiding a baseline missing necessary facts. All three real models
+complete it, while token/time/resource tradeoffs remain mixed. That pinned run
+preserves the recovered no-return disagreement and uses machine facts for the
+post-call path.
+
+The [return-coverage study](aarch64-return-study.md) fixes the BTI entry split
+and a separate false no-return promotion through the native owners. The fresh

+# Reuse proven native source refusals
+
+After the streamed-inventory model pair, main was fetched again and remained
+`150e996a8`. Baseline runtime is `b88c75df8`. Native engine remains
+`2e398e7229e30b6d2387a802db8a0050764119a6b457020d334855e36e69d6c5`.
+This is an experimental follow-up, with no PR or integration into main.
+
+## Observed redundant work
+
+Two identical real LLVM string queries in one target lease first hit the 64 MiB
+source ceiling after 8.363 seconds. The second still runs native analysis for
+3.024 seconds / 3.021736 CPU seconds, retaining another partial prefix and
+reporting cleanup uncertainty. The provider discarded every failed work entry,
+even a proven output-size refusal for the identical immutable native capture.
+The source budget cannot grow within that lease. Neither query produces valid
+string facts; absence must remain unknown.
+
+The same two-request probe after the change takes 7.603 seconds for the first
+refusal and 1.528 ms / 0.001567 CPU seconds for reuse. Only one partial source is
+captured, with the same readable Evidence handle on both errors. The added
+`cached_observation:{kind:"source_budget_refusal",scope:"target_lease"}` labels
+the original observation being reused; it does not report a fresh native run or
+current process status. Cold-time variation is not a causal speed claim.
+
+| Same two-request diagnostic probe | Wall s | Local family CPU s | Kernel family peak MiB |
+| --------------------------------- | -----: | -----------------: | ---------------------: |
+| Before                            | 12.406 |          12.192070 |                1,745.6 |
+| After                             |  8.579 |           8.364375 |                1,492.5 |
+
+This compares the same diagnostic intent, not successful LLVM analysis. The
+second original attempt adds a cleanup-uncertainty failure, whereas reuse keeps
+the original proven resource refusal without starting another process. Different
+cold costs and transient ownership observations prevent a pure latency ratio or
+general memory/speedup claim. The decisive signal is avoided native work.
+
+## Cache ownership and invalidation
+
+`NativeCaptureCache` owns pending/completed native work in one provider lease.
+It replaces the old map wrapper. It retains a refusal only for the understood
+`FactFailure` resource code, native-source scope, positive safe byte limit and
+observed lower bound above that limit, with a retained partial source ID and
+only the six understood refusal fields. Secondary file-cleanup uncertainty and
+unexamined metadata also prevent reuse. Classification copies own data properties without
+invoking getters; unknown/primitive failures retain their original identity.
+
+Cancellation, I/O, cleanup uncertainty, other resources and unproven constraints
+remain uncached. The cache never turns an unknown primary cleanup outcome into
+resource success. Error views are separate from the immutable retained refusal,
+so editing an SDK error cannot alter later Evidence IDs or limits. At most the
+existing 128-source policy's number of work entries is memoized. When that table
+is full, new producer results still return without adding retention; the shared
+application owner continues to bound native admission. This also bounds any future source/key aliases. No additional source budget is introduced.
+
+Keys keep the existing native request inputs, with target/engine/profile fixed
+by the owner instance. Catalog selectors do not change native capture arguments.
+Cache validity follows the immutable artifact capture and nonincreasing source
+budget, not live state. Successful captures retain the previous reuse semantics;
+close clears the cache after confirmed resource cleanup. A new lease gets a new
+owner. No cross-session negative cache is claimed.
+
+## Actual adapters, failures and verification scope
+
+Real LLVM SDK and Direct MCP checks pass refusal reuse, unchanged target/lease,
+identical refusal details except the explicit reuse label, one raw source,
+readable partial Evidence and exact full raw digest. SDK warm latency is 2.282 ms
+/ 0.001675 CPU seconds; Direct is 6.412 ms / 0.005566 CPU seconds. Their fresh
+first calls take 7.350 / 7.756 seconds respectively.
+
+The first scripted Code Mode check fails its cache-hit precondition because the
+first call reports `cleanup_incomplete`. It correctly does not reuse that
+uncertain failure, and the second native attempt takes about 2.905 seconds.
+Both partial raw captures independently validate target/engine/hash/length. The
+original verifier recorded phases/stack but placed the complete API observation
+after its assertions, so the failed API payload is not fully auditable. Preserve
+that limitation and the original failed receipt; do not relabel it a pass.
+
+The verifier now records replies before assertions and stops if cleanup is
+uncertain. One fresh scripted coverage repeat then reaches the proven-refusal
+path. In one actual MCP execution, the guest calls strings twice and Evidence
+once: the second call is 3 ms by guest `Date.now` (millisecond precision, separate
+warm CPU unmeasured), with the same handle and exactly one raw source. The full
+8.126-second program uses 8.119767 local CPU seconds. The two error results remain
+errors; successful composition does not establish successful LLVM analysis.
+This is a scripted coverage repeat after a verifier correction, not another
+model answer or a replacement for the failed observation.
+

+
+Both Code Mode attempts cost 22.997 family-wall seconds / 22.565754 CPU seconds;
+peak across them is 1,939.9 MiB, not the sum of peaks. These receipts are not a
+matched adapter performance ranking: verifier work and failure paths differ.
+All are one-CPU, 3 GiB early-stop / 4 GiB hard-limit, no-swap runs; payload-exit
+observers verify cleanup and OOM=0, including the failed attempt. Final exited-
+cgroup counters are unavailable. Kernel family memory includes file cache.
+
+All 116 experimental JS tests pass, including in-flight reuse, invalidation,
+mutable caller views, zero/false/null/unknown errors, noncacheable cleanup,
+accessor avoidance and bounded memo admission. Real FFmpeg selected facts,
+Evidence, bytes and stale-handle checks pass in SDK/Direct/Code Mode after the
+cache change. Cancellation/owned cleanup checks pass. Changed-file lint and
+format checks pass. After tightening the sealed-source/secondary-cleanup eligibility guard, the full
+116-test suite passes again, and captured SDK/Direct/Code Mode refusal DTOs all
+pass through that sealed contract in replay. That replay is a production-boundary
+check, not another live-provider or model run. Existing full-suite/resource-gate
+limitations from the
+[streaming study](streamed-inventory-study.md) remain. No new model trial was
+performed for this cache change; the earlier fixed-runtime model costs remain
+attached to that earlier runtime. Scripted probes consume no model tokens.
+
+LLVM and Node inventories still exceed the source budget. This optimization
+makes known refusal cheap; producer-side selective computation remains the next
+coverage/computation question. It does not improve provider parity or prove
+complex reverse-engineering superiority.
