Script metadata admission bounds retained identity and source-map strings to 8 MiB and 50,000 records. When a source-map URL cannot fit, the script identity remains and source-map coverage reports `resource_budget_exhausted`; rejected script observations are counted without retaining their IDs.

Encoding, character count, byte length and terminator facts must agree; supplementary UTF-8 characters count as Unicode scalars. Malformed output is an error, not an empty search.

Rows are validated one at a time, and the first contradiction stops Kuna. Text REA does not keep is dropped unassembled; kept text and retained rows are admitted against the REA process's live heap headroom as they arrive; a refusal is a `memory` resource constraint with `retryable: false`, and closing other targets or starting REA with a larger Node.js heap makes room.

-[#4387](https://github.com/morluto/rea/pull/4387), umbrella
-[#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`.
-Acquisition is linked in the [original Joplin verification](javascript-native-handoff-identity-2026-10-15.md).
-Its complete unpacked native files/assets accompany it. These trials use the
-actual application with **generic Electron 44.7.0**, fresh profiles and Xvfb.
-They exercise startup/cancellation, not a completed Joplin business workflow.
-
-Frozen verifier revision `279aa29a7` records source/runtime hashes before the
-final probes. The controlled cases hold a REA-side Playwright reply while the
-real application runs. They do not establish a naturally occurring Joplin stall.
-
-| Controlled condition                        | Observed result                                                                                        |
-| ------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
-| Main: first-window reply stays pending      | Still pending 20.001 s after cancellation; verifier watchdog fails                                     |
-| Fixed: same pending first-window reply      | Cancellation returned in 5.658 s; cancelled action retained                                            |
-| Fixed: initial snapshot reply stays pending | Cancellation returned in 5.335 s; no invented partial snapshot                                         |
-| 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:

-## 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

-## 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

-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

-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

-
-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 \
-  --profile-root /absolute/owned-packet/profiles \
-  --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.

-# Selected retained JavaScript observations
-
-Tracks #4190 under #4027. Base:
-`85eac7b92bac39bf2da6c00ebf6ba1b11b4c8d1f`. Initial working version:
-`f70b8c0bc512094938e817c083921e69aaacfcbe`; the final version additionally
-supports opt-in property-name discovery. Exact source hashes, all measured
-attempts and compact agent answers/operations are in the adjacent JSON record.
-
-The analyst knows several application-relative metadata/native paths and needs
-selected facts with their original identities and provenance. The previous
-module-reference view excludes those kinds. A full feature trace answers a
-broader relationship question; a real Joplin package trace exceeded the 10 MiB
-reply limit twice in #4190. Exporting retained Evidence and projecting it locally
-is a valid alternative, and is used as the completed baseline here.
-
-## 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.
-
-## Real input and reproduction
-
-Use the official [Joplin v3.7.21 Linux AppImage](https://github.com/laurent22/joplin/releases/download/v3.7.21/Joplin-3.7.21.AppImage).
-Acquisition and exact selective 7z extraction are documented in
-[native handoff verification](javascript-native-handoff-identity-2026-10-15.md#real-input-and-scope).
-Asset SHA-256:
-`5d202dcaca31e14206826aa3f04125e7c218dbc3dc3d98479d811efbd6b856c1`.
-ASAR: 233,575,014 bytes, SHA-256
-`767df409b18effe60421fbefcca873de237c7e813eac744ecdeebbc5e825a33a`.
-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
-retains package `@joplin/app-desktop` / `3.7.21`; keytar's observed physical bytes
-hash to `0700016bcd761cbe02d275f2046c7cc42f39f730a50d66e3d3307aa9d413373a`.
-That digest does not establish runtime execution. Deliberate `analysis_timeout_ms:1`
-retains native identity and unavailable `not-started` phases for
-`parse-local-source-map`, `parse-html-script-references`, and `parse-package-json`.
-Missing source-map original content is distinct from failure to parse the map.
-
-After pinned Node/npm installation, `npm ci` and `npm run build:cached`:
-
-```sh
-query='{"kind":"javascript-facts","where":{"paths":["ElectronAppWrapper.js.map","index.html","package.json","node_modules/keytar/build/Release/keytar.node"]},"property_keys":["path","bytes","file_kind","text_status","parse_status","json_parse_status","availability","operation","analysis_status","limitation","name","version","main","renderer"],"offset":0,"limit":64}'
-for mode in export view; do
-  node scripts/verify/javascript/retained-facts.mjs \
-    --artifact "$input_root/cases/available/app.asar" --mode "$mode" \
-    --query "$query" --rounds 3 \
-    --source-path ElectronAppWrapper.js \
-    --source-path ElectronAppWrapper.js.map --source-path index.html \
-    --source-path package.json \
-    --source-path node_modules/keytar/build/Release/keytar.node
-done
-```
-
-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)
-using `--memory-gib 8 --observe-payload-exit`: one CPU, 8 GiB hard limit,
-6 GiB early stop, no swap, 192 tasks; Node heap 2 GiB, `UV_THREADPOOL_SIZE=1`,
-`GOMAXPROCS=1`, `GOMEMLIMIT=3GiB`. Observer hashes and cleanup receipts are in JSON.
-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.
-
-## All actual agent attempts
-
-One valid trial per surface/task/version; no aggregate success rate or causal speedup.
-Resource columns cover the whole payload, including cleanup.

-
-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
-as a harness failure, with unavailable operation counts.
-
-Use the [specific artifact oracle](../../experiments/analysis-efficiency/javascript-facts-grade.py) on the compact JSON:
-
-```sh
-python3 experiments/analysis-efficiency/javascript-facts-grade.py \
-  docs/verification/javascript-retained-facts-2026-10-15.json
-```
-
-It checks actual receipt IDs, caller selection/deadline, exact native facts and
-processing entries. Its coverage check recognizes a partial declaration rather
-than validating arbitrary prose. Read the preserved original answers and
-qualifications: some trials cite a correct physical-byte observation plus an
-ASAR-entry observation outside the named native node. The initial candidate
-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.

-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**

-## 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.

-## 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 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 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 session admission.
+  SDK callers, CLI scripts and both MCP adapters use these same methods.
+- `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 have existing supervision, an 8 MiB
+capture budget and 1 GiB function-memory limit. Retained source storage is 64 MiB
+per target, with two resident indexes (each derived 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.
+
+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 fourteen 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.
+Repeated new native processes do not gain the API owner's warm result reuse.
+Its subsequent [bounded codec implementation](native-graph-transport-study.md)
+now returns the complete 21,349-operation VM graph in about 3.79 MB, inside the
+unchanged 8 MiB wire budget. Selected definitions/CFG reads and decoded Evidence
+work through both real MCP adapters; all graph fields and ordinary C/calls match
+the prior complete golden. Same-lease reuse is about 67 ms after a 39.7-second
+fresh capture, with resource limits and no OOM. The [next question/oracle](savepoint-control-oracle.md)
+start from names/error messages and exercise the new condition/CFG coverage.
+Two [real-model pairs](savepoint-control-study.md), including a discovery-guided
+repeat, answer both local guards correctly without a whole-report fetch. Code
+Mode uses fewer MCP requests, but whole-task costs are mixed and a large capture
+time variation remains unexplained. Both clients already provide JavaScript
+orchestration. Source fidelity is not machine equivalence, provider parity or a
+general speedup. The [native switch experiment](switch-study.md) now exports and independently checks
+182 labels over those 149 targets, exposes selected case-to-edge relations and
+keeps them readable when a 2 MiB native output budget omits the full graph.
+Both real models now answer the selected-case/default question correctly using
+one retained capture and focused case/byte reads. Code Mode uses fewer tokens
+in this pair, but unequal native capture time and extra client polling confound
+the comparison. Whole-task costs and limits are in the same study; a general
+efficiency advantage remains unproved.

+# 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.

+# 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.

+# Client waiting and whole-task cost
+
+The [selected-case pair](switch-study.md) exposes one-second client polls after
+the snapshot execution yields. Direct makes six waits (three one-second then
+three ten-second requests); Code Mode makes three one-second requests. Five
+direct and two Code Mode wait responses still report a running cell. Initial
+execution yields after about 31 seconds in both lanes. This is observed client
+behavior, separate from MCP attempts and native source-capture time.
+
+Native latency remains variable, including in sequential scripted MCP runs
+without models. The [overlap canary](overlap-study.md) did not establish a cause.
+No analysis acceleration or cache invalidation change is proposed here.
+
+## Frozen diagnostic
+
+The opt-in runner flag `--guide-long-waits` appends exactly the same client wait
+policy in both lanes: resume an already-running cell with a 30,000 ms wait,
+respect the advertised schema, and do not sleep or duplicate analysis merely
+to check progress. It changes neither the initial execution yield policy nor
+the provider/Code Mode deadlines. It supplies no analysis facts. The policy,
+flag and instruction digest are recorded in each trial's settings. Older runs
+without this flag remain a separate stratum.
+
+Run Code Mode first, then direct, with the unchanged
+[question](sqlite-switch-question.txt) and [oracle](switch-oracle.md), final
+`a9ca8a8a...` engine, complete four/eighteen-tool catalogs and the same exact
+discovery/envelope guidance as the first pair. Use fresh leases and isolated
+model workspaces, requested `gpt-6.1-sol/high`, Codex 0.161.0 and the same one-CPU,
+4 GiB hard / 3 GiB early-stop resource policy. No runtime edits during the pair.
+Local records use `sqlite-switch-{codemode,direct}-v2*`.
+
+Review complete answers against the frozen independent machine oracle and
+retained source, including selector widths, all requested cases, signed target
+arithmetic, case/edge identities, native default versus machine out-of-range
+guard, provenance and unknown runtime behavior. Require one VM capture and
+focused reads; a lower token count without a correct answer is not a win.
+

+# Task coverage before cost comparison
+
+The callable projection now also has a completed [PHI-format model pair](trials.md).
+Both answers reconstruct all four alternatives with exact retained identities,
+independent machine/string checks and partial-scope limits. An observed reference
+lookup mismatch adds work in the direct lane; its costs remain recorded and that
+discovery boundary needs correction before another same-question comparison.
+
+Code Mode can only compose facts the underlying API actually supplies. A task
+cost is comparable after reviewing the completed answer and its evidence. A
+successful tool call, fewer response bytes or more graph records is insufficient.
+No claim of complete reverse-engineering capability follows from these tasks.
+
+The [boundary-facet question/oracle](boundary-oracle.md) now also has a completed
+real-model pair. Both answers correctly use calls and boundary values despite
+full-graph capacity failure, reuse one VM analysis and preserve definition/use
+and runtime uncertainty. Code Mode is faster in this sample and uses slightly
+less cumulative input, while uncached input and maximum response context are
+higher. See the full costs and independent source checks in [trials.md](trials.md).
+This verifies the narrower recovered-call capability; it does not supply selected
+definition bodies when the full graph is unavailable.
+
+The next completed pair reuses that exact question and oracle after adding compact
+call counts to the shared snapshot facet. Both adapters receive the same new
+metadata, derived after native validation from the complete retained call set;
+the engine, fact methods and selection semantics are unchanged. The hypothesis
+is that avoiding full-set paging for these counts reduces task costs. Count
+coverage remains recovered block-member calls, not complete machine calls or
+runtime binding. Both answers satisfy the same oracle and avoid call-set paging.
+Cumulative input is lower in both new samples, but elapsed/uncached costs improve
+only for direct; direct now beats Code Mode within the pair. These observations
+support useful shared aggregates, without establishing a general efficiency
+effect. Selected rows/full source Evidence remain available for composition and
+audit; all native VM function records equal the earlier captures.
+
+The atomic direct and Code Mode lanes share the same method registry, provider
+owner, selectors, failures and retained sources. The traditional lane selects
+relevant production tools, including the discovery route advertised by its
+errors; its selection and extra discovery guidance are recorded. Use the same
+target, engine, authority and question. Freeze runtime files for each model batch.
+Keep full original errors, retries and partial answers in the record. Never show
+this oracle document or repository sources to a measured model.
+
+Review task facts separately from answer length. A confident false physical
+branch target fails the value-origin task even if its reconstructed IR equation
+is right. An answer stopping at an import stub does not complete a task whose
+other lane traces the formatter implementation. A bounded missing graph is not
+an empty graph. Mark unsupported facts unknown and report incompletion when the
+question actually needs them.
+
+Cache regimes are distinct: fresh analysis captures, a reused capture in the
+same lease, a validated persistent project in a new session, OS file cache and
+the model's reported prompt-cache tokens. These experiments do not clear the OS
+cache. The prototype has no cross-session result cache. Whole-model cold and
+reused-project trials therefore remain separate from the API-only same-lease
+cache benchmark. Report cumulative input, included cached input, uncached input,
+output and included reasoning; do not invent server compute or price savings.
+
+All resource trials are serial with one CPU, 4 GiB hard memory, early stop at
+3 GiB, and an observed cleanup receipt. Kernel family memory includes charged
+file cache. A single stochastic trial is an observation, not a reliable ranking;
+API-only replay cannot replace real model trials or establish their token cost.
+
+The CLI transcripts establish that all lanes have a client JavaScript `exec`
+surface, even with `code_mode=false` requested. Count actual model responses,
+client dispatch/wait calls and MCP requests separately. This comparison is not
+an ablation against a client incapable of code composition. The optional
+`agent-trial.py --normalize-mcp-guidance` adds identical envelope/stopping guidance
+to any lane: select `structuredContent` or parsed text once, avoid printing both
+encodings, stop when supported and close the target. It is recorded explicitly;
+the initial SQLite and VM rounds do not have that later guidance. Their native
+analysis commands/profiles also differ (selected functions versus production
+project and facet workflows); engine equality alone does not isolate Code Mode.
+
+The pinned SQLite artifact is `/usr/lib/x86_64-linux-gnu/libsqlite3.so.0.8.6`,
+SHA-256 `2e6eef9a727f081f0d453b4e5e6cbd8b9ef8b6f86cbf7681cbad444d3b0b55c8`.
+The malformed-MATCH oracle and earlier unequal-depth results are retained in
+[trials.md](trials.md). The next VM task is fixed in `sqlite-vm-question.txt`
+before model trials. Its oracle is checked with GNU `objdump -d -M intel` over
+the shipped executable, independently of both model answers and Kuna IR. Dynamic
+symbol inventory (`nm -D --defined-only`) identifies `sqlite3VdbeExec` at
+`0xea6d0`. Reconstructed C and printer line mappings help locate checks, but do
+not replace the physical instruction evidence:

+
+The VM's real native-IR exporter exceeds its operation capacity. It retains
+3,654 lines of reconstructed C and complete source Evidence. This task tests
+whether a model can use those available facts plus selected physical instruction
+windows without inventing a recovered graph. Its local status `5` must not be
+silently promoted to an unconditional final function return: shared error
+processing can still change behavior. No target execution is authorized here.
+
+The post-serialization-fix Pragma task is fixed in `sqlite-pragma-question.txt`.
+It tests a previously inaccessible code facet rather than treating a byte-limit
+failure as a fast completed answer. The two experimental calling modes use the
+same twelve methods and new engine digest `2290e8b1…`, with common normalization
+guidance enabled in both. There is no new traditional cost cell for this task.
+For the same pinned SQLite artifact, independent GNU instruction checks establish:
+
+- `sqlite3Pragma` entry `0xb90e0`; value-pointer test `0xbae56` / branch `0xbae5c`
+  distinguishes the read path from change handling at `0xb9b8c`.
+- `0xb9b90` tests connection byte `+0x65`; zero branches at `0xb9b94` to diagnostic
+  selection at `0xbc58a`. This precedes the additional selector-one bypass at
+  `0xb9b9a` / `0xb9b9f`, so their ordering must be preserved.
+- Allowed local update computes `(value+1)&7`, substitutes one for zero, and
+  stores the selected record's byte `+0x10` at `0xb9bdc`; byte `+0x11` becomes one
+  at `0xb9be3`. The input interpretation and source member names are derivations.
+- The actual diagnostic call is `0xbc596` through `sqlite3ErrorMsg@plt` at
+  `0x2a1e0`; `0xbc59b` jumps to common cleanup `0xb9293`.
+- Cleanup releases both temporary strings, checks the stack canary, and returns
+  at `0xb92d9`. Do not invent a fixed numeric return from this reconstructed
+  void routine. No SQL-level runtime trigger is demonstrated.
+
+Pragma's complete retained code and mappings are checked equal before/after the
+serialization fix. Its recovered graph remains explicitly unavailable at the
+encoded-byte capacity; that is a coverage limitation in both experimental lanes.
+
+The next seeded table-composition task is fixed in `sqlite-table-question.txt`.
+Both experimental modes have the same thirteen methods including `bytes`; a
+traditional comparison is not claimed because its selected catalog/available
+Kuna byte capability has not been established for this task. GNU disassembly of
+the pinned artifact shows `sqlite3GetToken` at `0xe1480`: unsigned input byte load
+at `0xe1480`, class-table base `0x12bcc0` at `0xe1484`, bound `0x1e` at `0xe1492`,
+class reload `0xe1498`, jump-table base `0x12b600` at `0xe149c`, sign-extending
+32-bit table load at `0xe14a3`, base addition `0xe14a7`, indirect jump `0xe14aa`.
+The out-of-range path begins `0xe14f8`.
+
+Independent direct file reads are valid here because `readelf -lW` binds this
+artifact's selected addresses to the same file offsets in its read-only LOAD
+segment (`0x11a000..0x154bfc`). A Python `struct.unpack_from('<i', ...)` check of
+the actual table bytes gives these initial dispatch facts, before model trials:
+
+| Input byte | Class | Signed displacement | Initial machine destination |
+| ---------- | ----: | ------------------: | --------------------------- |
+| `0x2d`     |    11 |             -302928 | `0xe16b0`                   |

+
+## Cross-function facts work; adapter gains remain mixed
+
+The structured-call experiment closes an observed native export gap: the call's
+fspec annotation does not identify its target code address, and an argument's
+SSA storage is not its passing location. Reusing the native call-spec owner now
+allows a model to connect a caller value to a callee input without parsing a
+display string. Real SQLite answers support this connection with machine
+instructions, trace a shared parenthesis counter across two functions, and
+preserve the limits of recovered slots, aliases and runtime feasibility.
+
+The first question pair omitted oracle-required alternative return paths in both
+answers. Its wording was less explicit than its oracle, so that result stays a
+partial-coverage record. A new question clarification was committed before the
+next pair; both then satisfy the task. The failed engine-pin setup launch also
+remains recorded. No sample is silently converted into a completed task.
+
+In the correctness-equal pair, Code Mode uses 596,978 cumulative input tokens and
+156.821 seconds versus direct's 611,321 and 147.424 seconds. Uncached input,
+output, largest observed response input and family CPU are higher for Code Mode;
+family memory peak is lower. Both use the same fourteen fact methods and a client
+with JavaScript dispatch. The evidence supports usable composable call/input
+facts, without proving that this server adapter is faster or cheaper. Broader
+complex-software superiority and provider parity remain unproven.
+
+Two remaining boundaries deserve independent experiments. First, the initial call view lived inside full recovered IR, so graph capacity
+could hide a small otherwise useful call view. The next exporter revision now
+captures calls and their boundary values independently; real VM verification
+retains both while the graph exceeds capacity. Second, shallow outgoing references should serve a callee/reference list before
+requesting deeper argument/value recovery. The subsequent implementation now
+exposes Kuna's existing `xrefs --from` through the shared parser, with native kind
+filters, explicit scope and paging. Real VM known-target references match an
+independent disassembly pair set, and remain available when the full IR facet
+exceeds capacity. The next pre-pinned model question measures this use directly. Keeping those costs
+and coverage distinctions explicit is more useful than treating a smaller tool
+catalog as proof of better analysis.
+
+The shallow-reference question now completes through both real-model adapters.
+Each composes 396 VM reference rows into 171 exact destinations and 16 calls to
+the selected PLT address, then distinguishes a real stack-check call absent from
+optimized IR. Both keep unresolved indirect/discovery/runtime limits. Native
+reference pairs from both model sessions match the complete independent set of
+396 direct immediate machine calls; the separate 21 indirect instructions are
+not silently included in those known-target totals.
+
+In this one pair, Code Mode takes 93.837 seconds and 264,680 cumulative input
+versus direct's 106.183 and 285,086. Their maximum observed response input
+contexts are almost equal. This is useful positive evidence for selected facts
+plus local aggregation, while prior completed tasks show mixed adapter costs.
+It supports continuing the experiment, not a universal speed/token/provider
+superiority claim. Tool coverage and representation semantics were prerequisites
+for this comparison: a recovered-call-only view would have missed a real call,
+and VM full-IR capacity cannot establish that its shallow references are absent.
+
+An additional shared CLI/API run with the unpatched stock Kuna 1.833 executable
+also returns the same 396/171/16 VM aggregates, with fresh owned HOME/cache. The
+outgoing-reference capability uses native support, independently of the opt-in
+IR exporter. It takes 3.044 family wall / 2.695 CPU seconds and 182.6 MiB peak,
+with cleanup verified and OOM 0; these scripted costs are not model-token data or
+an adapter comparison. Stock external-spec freshness is still outside the engine
+binary digest. Full repository typechecking remains resource-limited as recorded
+in `native-engine.md`; source build, focused tests, changed-test typing and full
+lint/module checks pass.
+
+The bounded call-rooted definition projection now supports a local VM PHI task
+that full-graph capacity previously prevented. Four real-model answers over two
+revisions correctly recover both PHIs, all four alternatives and machine
+transfers, with source identities and global partial coverage retained. This is
+selected static-task coverage, not general complex-software superiority.
+
+The discovery correction removes an observed name-list miss and fixes defaulted
+input schemas, but the second pair does not show stable cost improvement. Direct
+has a 120-second native timeout before a successful retry; Code Mode changes its
+query strategy and costs more than its first run. The complete costs and failure
+remain in [the ledger](trials.md#phi-alternatives-after-named-discovery-correction).
+Fairness requires sufficient facts, correct discovery and honest retry reporting.
+
+The wide-PHI experiment provides a more precise candidate atom: an input slot is
+an individually selectable relationship, not just an array inside an operation.
+Its identity includes the operation and slot index; several relationships can
+share one value while preserving different predecessor edges. A value definition
+can then be composed with selected operation/value reads. Both measured models
+recover those distinctions and separate retained-node absence from unretained
+membership without fetching all 156 slots.
+
+This validates the shared query boundary, not adapter superiority. Code Mode
+groups the same seven fact requests, but four discovery lookups erase the
+MCP-request reduction at the observed model-response/client-dispatch level. Its
+95.699 seconds versus direct's 91.817, nearly equal cumulative input and lower
+uncached input remain a mixed single sample. Discovery is itself part of the
+analyst workflow and deserves a separate test. Broader behavior reconstruction,
+complete large-function CFG/use coverage, aliases and a universal RE basis are
+still unproven. See [the complete scoped results](trials.md#selected-wide-phi-input-relationships).
+
+The same question after adding a static method index again completes correctly
+through both adapters. Code Mode now uses two discovery calls instead of four,
+without changing the seven fact reads. Observed model responses decrease by one,
+but total time increases slightly; direct also takes longer and uses fewer input
+tokens without changing query counts. The second pair is approximately 98.8
+seconds each, with more cumulative and less uncached input for Code Mode. This
+supports the index's discoverability, while leaving whole-task cost mixed.
+
+There is a further distinction to test: an atomic fact API does not itself make
+native computation atomic. A fresh selected-slot question still incurs an entire
+function decompilation and C rendering. Phase costs are unmeasured, so neither
+removing C nor introducing persistent state is yet justified as a speed fix.
+Measure that boundary before claiming analysis-time improvement from narrower
+fact responses.

+# Native computation and retained fact coverage
+
+This diagnostic separates native computation from fact selection and Code Mode
+dispatch after the wide-operand model pairs. It does not change those adapters
+or establish model-token savings.
+
+## Phase instrument and actual measurements
+
+Use experiment commit `7d0da075e` and its versions of both patches to reproduce
+these historical measurements. Apply `kuna-native-ir.patch`, then
+`kuna-atomic-timing-diagnostic.patch`, to Kuna
+`fe01d6294eb0d1053ce343c8943646df88e143fc`. Reuse existing compiled specs and the
+one-job opt-level-1 embed-specs build in `native-engine.md`. Preserved engine:
+`c755184455b8fe8950a5194788d954bc0476602779b6dd614cb893a230f6fde7`;
+overlay: `b2ddfd5b6d3fc4a386cfbb07d97fbd0fcbfd8279837ce68327e62baa3e0f3018`.
+The preceding `a0685486...` public executable remains independently preserved.
+
+The instrument requires `--atomic-facts` and the exact environment value
+`KUNA_EXPERIMENT_ATOMIC_TIMING=1`. It emits nine sequential per-function wall
+intervals to stderr, excluding logging time from the next interval. Disabled
+instrumentation emits none. Analysis parameters and JSON facts are unchanged.
+These are phase wall times, not phase CPU. Loading, preparation before the drive
+and final output encoding are outside the intervals; the residual cannot all be
+attributed to one phase.
+
+`profile-native.mjs` uses production target/installation/process owners and a
+private runtime/cache root. Its diagnostic launcher adds only the timing flag;
+ambient environment is not persisted. It measures two new native processes:
+fresh private cache, then the same cache/staged input. This second process is
+distinct from the API owner's warm result-cache hit. Complete stdout/stderr and
+digests are retained before validation. OS cache remains uncontrolled.

+Pre-render/tail metadata also appear in the nine-interval raw receipts. `*` VM
+full-graph collection fails its early operation-capacity check; these numbers

+and its repeat. The disabled helper control also agrees, with zero timing rows.

+
+All use one CPU, 4 GiB hard / 3 GiB early-stop bounds, verified cleanup and OOM 0.
+Kernel peak includes charged file cache, not RSS. Final build keeps the same
+digest. Patch forward/reverse and lenient `check-spec` pass; full native corpus,
+stages and workspace gates remain unexecuted. No upstream commit/PR or integration
+readiness is claimed. Receipts/raw sources are local
+`phase-timing-{vm,helper,helper-off}.json*` and resource logs under
+`.cache/atomic-codemode/`.
+
+C rendering is below 1% of this VM request; skipping it cannot remove the
+approximately 34-second drive. The helper instead spends most time outside the
+instrumented phases, requiring further profiling before choosing persistent
+state. Same-cache new processes reanalyze. Previously measured same-lease API
+source reuse remains a separate approximately 40 ms path.
+
+## Lossless full-graph encoding feasibility
+
+The earlier diagnostic source has 21,349 operations, 35,755 values and 1,229
+blocks, with no omitted definition IDs. Its whole document is 17,801,972 bytes;
+the graph is 17,008,223 bytes, including 2,255,616 bytes of operation display and
+90,013 bytes of value type names. Plain tuple packing was still too large.
+
+```sh
+python3 experiments/analysis-efficiency/resource-run.py --observe-payload-exit -- \
+  python3 experiments/atomic-codemode/measure-native-encoding.py \
+  /absolute/diagnostic-native.json /absolute/new-encoding-report.json
+```
+
+Gzip level 1 makes the graph 2,020,464 bytes. Hypothetical documents retaining
+ordinary C/metadata/calls and replacing only the graph with a typed envelope are:
+
+| Encoding      | Entire JSON bytes | Existing transport budget |
+| ------------- | ----------------: | ------------------------: |
+| gzip + base64 |         3,487,776 |                 8,388,608 |
+| gzip + hex    |         4,834,749 |                 8,388,608 |
+
+The graph byte roundtrip is exact. Python gzip/base64 encode costs 69.037 ms
+wall / 69.037 ms CPU; decode 34.632 / 34.571 ms. Whole sizing task: 0.826 wall /
+0.654 CPU seconds, 169.8 MiB peak, cleanup verified and OOM 0. These are offline
+Python feasibility measurements, not Rust/Node timings, native output, public
+support or agent savings. Source SHA-256:
+`0a31513350be440983094710197b155a2ec8c49d28852bb20a524292091637b7`;
+reproducible receipt: `full-graph-encoding-repro.json` beside its resource log.
+
+This supports testing bounded lossless transport before introducing live-function
+ownership or repeating analysis for missing definitions. Required checks include
+allocation/encoding growth, bounded inflation, exact format/length/row admission,
+malformed-graph isolation from calls/C, complete Evidence access, actual CPU and
+memory, fallback behavior and real-model workflows. The shared owner must return
+selected facts rather than send an encoded graph to the agent. The current
+public engine at this sizing checkpoint still has a bounded call-rooted
+projection. The [subsequent implementation](native-graph-transport-study.md)
+now verifies full recovered-graph access through bounded native/Node encoding
+and both public MCP adapters; real-model verification remains separate.

+# Native recovered IR experiment
+
+Stock Kuna's diagnostic text omits CFG successors and does not encode operand or
+phi edge identities. `kuna-native-ir.patch` is a read-only exploratory exporter
+against [Kuna v1.833](https://github.com/Noelo-Lab/kuna/tree/fe01d6294eb0d1053ce343c8943646df88e143fc).
+It is not an upstream release or an integrated REA capability. No upstream commit,
+PR or merge is being made.
+
+`decompile --json --atomic-facts` captures the live function that produced C.
+The default path does not collect the facet. Graph records include ordered CFG
+edges, native value identities, indexed operands, outputs and phi input bindings
+to particular incoming edges. Duplicate instruction origins or predecessor blocks
+do not collapse identities. Values are local to one snapshot. Constant offsets
+remain hexadecimal u64 address-space offsets, with width and annotation status
+separate; they are not arbitrary-width computed bitvectors.
+
+`native-ir.mjs` owns validation, immutable indexes and selected reads.
+`control-dependence.mjs` derives control dependence using immediate
+postdominators of the reversed graph, with linear retained graph state and a
+bounded work count. It treats zero-successor recovered blocks as exits and
+considers finite paths only. Exit-unreachable blocks, indirect-branch operations,
+missing definitions, runtime successors and memory alias limitations stay
+explicit. This is not a proof of feasible runtime paths.
+
+The shared API adds `values`, `blocks` and `relations(kind:"controllers")`.
+Diagnostic SSA sessions report these missing capabilities explicitly. Native
+definition/use edges include operand and phi bindings; diagnostic printed
+occurrences retain their original, weaker semantics. CLI, SDK and both MCP
+adapters use the same owner. Ordinary source summaries are compact; `evidence`
+retains the exact command argv and separate display argv, complete output and
+digest. Earlier trials substituted display paths in `arguments`; they must not
+be retroactively claimed to have captured exact argv.
+
+To reproduce, check out the pinned upstream revision in a disposable directory
+and apply this patch with `git apply`. Reuse already compiled `.sla` files from
+the corresponding stock release under the same relative `specs/` paths; do not
+recompile specs or replace existing unrelated files. Build from the REA root:
+
+```sh
+env CARGO_INCREMENTAL=0 CARGO_PROFILE_RELEASE_DEBUG=0 \
+  CARGO_PROFILE_RELEASE_OPT_LEVEL=1 CARGO_PROFILE_RELEASE_LTO=false \
+  CARGO_PROFILE_RELEASE_CODEGEN_UNITS=16 \
+  python3 experiments/analysis-efficiency/resource-run.py --observe-payload-exit -- \
+  cargo build --manifest-path /absolute/kuna/decompiler/Cargo.toml \
+  --locked --release -j1 -p kuna-cli --features embed-specs
+```
+
+Select that executable through `REA_KUNA_COMMAND` and explicitly pin its actual
+SHA-256 through `REA_ATOMIC_NATIVE_IR_ENGINE_SHA256`. Native IR requires embedded
+specs and rejects a caller-supplied `--sleighpath`; the provider creates a fresh
+owned engine cache per lease. The executable digest therefore covers its embedded
+assets, without reusing an unvalidated external spec cache. The current prototype
+uses optimization level 1, not the stock release's assumed optimization profile;
+comparisons must retain this difference or use the same engine in all lanes.
+
+Native extraction bounds blocks/operations at 12,000, values at 36,000, input and
+CFG edges at 50,000 and display text at 2 MiB, before the 8 MiB transport bound.
+Capacity overflow makes this facet unavailable, preserving C and a reason. The
+provider retains at most two 8 MiB native indexes (two 2 MiB diagnostic indexes)
+and 64 MiB of complete source captures per lease. The outer observer still
+enforces one CPU, 4 GiB hard memory and early termination at 3 GiB.
+
+Real Linux zlib verification produced 3,860 operations, 5,898 values, 472 blocks,
+779 CFG edges and 790 phi operations. Its 5,533,649-byte native JSON has no omitted
+definitions or reported producer issues. C is byte-identical to the previously
+captured stock 1.833 JSON (52,431 characters), and line mappings are identical.
+The CLI composition independently discovers the string, owning function, store
+and its two local controllers. Its observed cold session takes 9.191 seconds,
+8.887 process-family CPU seconds and 198.9 MiB kernel memory peak, with verified
+cleanup and zero OOM kills. This scripted lane is not a real-model cost result.
+
+Targeted JS checks cover malformed/foreign identities, dangling relations, phi
+order, exact hex offsets, immutable facts, loop/exit coverage, resource failure,
+and all 64 four-node DAGs against an independent path-enumeration oracle.
+Upstream `check-spec` passes. The full upstream corpus, stages and workspace gates
+have not run; this patch is not declared upstream-ready. The model comparisons
+and subsequent boundary findings below do not establish wider provider parity.
+
+The value-origin model comparison exposed a representation boundary: optimized
+recovered blocks can absorb a machine predecessor, so an IR edge is not an actual
+branch instruction target. The experimental API now names operation locations
+`origin_address`, their selector `origin_addresses`, and block locations
+`origin_start`; printed CFG targets use `target_origin`. These replace the old
+ambiguous fields without aliases. Historical captures retain their pinned old
+contracts. Raw upstream JSON is preserved unchanged in Evidence.
+
+The added `instructions` method batches selected machine-address windows, using
+Kuna's existing [disassemble CLI](https://github.com/Noelo-Lab/kuna/blob/fe01d6294eb0d1053ce343c8943646df88e143fc/decompiler/crates/kuna-cli/src/disassemble.rs),
+with exact bytes, decoded text, extent, coverage and per-window errors. Kuna
+already has focused agent-oriented read surfaces; its port ancestry does not
+establish which primitives are missing. No assembly decoding or branch-target
+parser is duplicated in the MCP adapter.
+
+Windows are capped at 4,096 decoded rows and 16 windows per call, sharing the
+8 MiB capture and 64 MiB retained-source budgets. A real maximum-row CLI test
+returns 4,096 rows in an 842,106-byte source, taking 1.227 family wall seconds,
+1.042 CPU seconds and 112.0 MiB kernel memory peak. Both real stock and patched
+MCP tests preserve good windows alongside an unmapped-address failure and report
+the actual `JA 0xe26d` / `JMP 0xd9c9` bytes. The representation revision had 33
+targeted tests; its subsequent real-model trial is recorded below.
+
+That fresh trial now verifies the missing machine path correctly; see
+[actual task costs](trials.md). The SQLite task then exposes a separate missing
+primitive: name/alias lookup across distinct callable entries. `functions` now
+reuses the production inventory parser, preserving every matching entry, import
+stub ambiguity, original aliases, clipped extents and unknown runtime binding.
+The inventory is read/validated once per lease, and query/field/page selection
+returns only the requested view. Batch xref and instruction reads share one
+partial-outcome owner, retaining good observations and source IDs on failures.
+
+A real `sqlite3VdbeExec` capture at `0xea6d0` also exceeds the graph export's
+operation capacity while producing 126,519 characters of valid C. The old adapter
+incorrectly rejects the entire capture. The revised owner validates the function
+envelope and input identity independently, then models graph availability as a
+facet result. Code and its language remain available under the same handle;
+graph counts stay unknown and graph reads return their reason and Evidence ID.
+The real MCP regression reads 3,654 code lines after the graph failure and verifies
+that `sqlite3Fts3ErrMsg` has distinct entries `0x268f0` and `0x5efc0`. Native graph
+capacity remains a real limitation, not a resolved scalability claim.
+
+`verify-cache.mjs` measures a real cold/warm pair within one open lease. Cold zlib
+snapshot reading takes 6,934.4 ms / 6.928 family CPU seconds; warm reading takes
+67.7 ms / 0.068 CPU seconds and preserves the exact snapshot/Evidence ID. The
+cumulative kernel memory peak is 275.1 MiB for both phases; the warm number is an
+upper bound on its isolated phase peak. This is an API-only measurement, with no
+model token result or cross-session cache claim. Targeted tests now total 38,
+including late cancellation retaining partial facts and their provenance.
+
+A subsequent real boundary sweep found a different loss of usable facts:
+`sqlite3Pragma` (`0xb90e0`) and `sqlite3Parser` (`0xb3d00`) stay below the row
+limits but overflow the provider's 8 MiB stdout budget. Both public snapshots
+fail, losing C as well as IR. A separate diagnostic capture with a stated 32 MiB
+observer limit establishes the exact producer sizes; it is not relabeled as a
+successful public-provider workflow. The old engine is preserved locally by its
+`7d357e75…` digest for historical reproduction.
+
+| Function        | Previous pretty JSON bytes | Revised source bytes | C characters | Revised graph                                   |
+| --------------- | -------------------------: | -------------------: | -----------: | ----------------------------------------------- |
+| `sqlite3Parser` |                  8,492,810 |            4,526,811 |       50,508 | All 5,164 operations retained                   |
+| `sqlite3Pragma` |                 16,728,407 |              136,501 |       67,300 | Explicitly unavailable at encoded-byte capacity |
+
+The structural fix is at the producing serialization boundary. Atomic output
+uses the existing record producer and shared compact ASCII-safe writer.
+`--atomic-output-bytes` takes an explicit encoded-document budget (default 8 MiB);
+the provider passes the same bound it supervises. The writer checks each encoded
+write before growing its bounded buffer, accounting for escaping and newline.
+If necessary, the document drops only the graph and records an exact facet
+failure. C, line mappings and metadata survive under the same Evidence. If even
+the base document cannot fit, the command fails rather than clipping it or
+repeating the analysis. Ordinary non-atomic JSON keeps its previous formatting.
+Row limits alone never promise that the whole encoded graph fits.
+
+The rebuilt local engine is SHA-256
+`2290e8b13caabe30aab6832ab163d92925b2e652eebf7fc0cdbe65b889cb251b`
+(same pinned source/release profile plus the revised patch). Real Code Mode MCP
+verification succeeds for both functions. The preserved C and line mappings are
+identical to the earlier full diagnostic captures; the Parser graph is also
+deep-equal, and retained source hashes verify. Pragma's unknown graph counts and
+failed graph reads retain the correct source ID. No limit was increased.
+
+The first successful revised MCP check took 13.721 family wall seconds, 13.461
+CPU seconds and 326.9 MiB kernel family peak, with verified cleanup and no OOM.
+This is a two-function API regression, not a model-cost comparison or a claimed
+analysis speedup. Native writer/escaping checks (14) and graph-only fallback (1)
+pass in the release test binary; the shared JS tests (38), SDK ownership probe,
+lint and patch apply/reverse checks pass. Full upstream corpus/stages/workspace
+gates still have not run. The first MCP launch used a stale pre-format-build hash
+and was correctly refused; the retained successful retry uses the digest above.
+
+The `bytes` primitive reuses Kuna's existing `read --as data --json` protocol.
+Unlike instruction decoding, it asks for an exact byte range. It disables the
+global `listing` / `fast_funcdisc` passes for this data-only query; instructions
+retain their existing profile. A native probe returns exactly equal JSON with
+and without those flags. Its 484 / 290 ms timings share a workspace and run in
+that order, so they do not establish an isolated speedup. Native/source ownership,
+freshness, decoded-window admission and partial batches remain shared.
+
+Real public MCP checks pass in native Code Mode, native direct and stock 1.833
+Code Mode: a known 53-byte string, a 4-of-16-byte read at a mapped-image boundary,
+an unmapped address, same-source cache reuse and the 64 KiB maximum. Both adapter
+catalogs validate after SDK conversion. The byte parser rejects wrong subjects,
+contradictory duplicated hex, invalid extents and rows, and preserves exact u64
+addresses. Completeness follows examined byte coverage rather than the native
+truncation flag. It never claims these loaded-image bytes are live memory or
+proves an original-file mapping. Targeted JS tests now total 41.
+
+## Structured call relations (wire version 2)
+
+The next observed gap was input zero of CALL: a native `fspec` annotation is an
+internal reference, not a code address. The read-only `atomic_calls.rs` exporter
+now uses the existing `FuncCallSpecs` owner for recovered entry/name, model flags,
+argument passing storage and stack offset. A single operation-to-spec index
+avoids a linear lookup for every call. Input slots and SSA IDs remain separate
+from passing locations. Finalized storage is admitted only at matching arity;
+locked prototype storage is the alternative. Shifted inputs, placeholders,
+missing specs, unavailable storage and unresolved indirect entries remain
+explicit. There is no display-text parser or original-source ordinal claim.
+
+`calls` provides ID/origin filtering, field projection and paging through the
+shared SDK/CLI/MCP owner. Callee `values(is_input:true)` exposes retained input
+values for exact storage candidate matching. Source schemas, unique call
+ownership, call coverage, operand indexes/values and output identities are
+validated before exposing an index; a bad or old-version graph preserves valid
+C. Machine CALL instructions remain the independent check of a recovered edge.
+
+Engine `64c6b3fe5737056fc29c10b0aad6c7cbd489ad7d17bd1726141b77bdcf5e15b7`
+uses the same upstream revision, embedded specs and one-job build profile.
+The rebuild took 317.090 family wall seconds, 315.808 CPU seconds and a 2,145.695
+MiB kernel process-family memory peak (including charged file cache), OOM 0.
+The previous compact exporter engine is preserved by its SHA-256 locally.
+
+Real SQLite MCP verification passes both adapters, including a composed Code
+Mode join: caller `0x65211 -> 0x64060`, argument passing storage
+`register:0x38/8`, one matching callee input, and a bounded definition slice from
+the context updates to that input. Formatter calls `0x5f031`/`0x5f062` point to
+`0x2adc0`/`0x27e50`; their fspec offsets remain `0x10000`/`0x10001`.
+All three functions' C, ordinary metadata/line mappings, blocks, operations,
+values and existing coverage equal retained earlier captures. Those earlier
+sources were pretty-printed: encoded-size changes are not a call-exporter
+performance result. The structured call counts are 8, 33 and 2 respectively.
+
+The Code Mode verifier took 7.872 family wall / 7.573 CPU seconds, 297.1 MiB;
+the direct verifier took 7.771 / 7.499 seconds, 278.7 MiB. These differ in assertion
+calls and warm file-cache state, so they are verification receipts, not a
+controlled adapter speed comparison. Both verified cleanup and OOM 0. The
+existing real zlib controller/phi/instruction verifier also passes with this
+engine (10.992 wall / 10.795 CPU seconds, 285.7 MiB, cleanup verified, OOM 0).
+`check-spec` passes in its default lenient mode; full upstream gates still have
+not run. The independent cross-function question and acceptance criteria are in
+[call-oracle.md](call-oracle.md), pinned before model evaluation.
+
+The strengthened verifier additionally reads all five retained indirect calls in
+this parser and checks their unknown targets. Machine bytes `ff5328` at
+`0x644eb` independently describe a register-indirect CALL. The Code Mode rerun
+passes (16.628 wall / 8.239 CPU seconds, 300.5 MiB); native test compilation was
+also active on the same CPU, so its wall time is not an isolated performance
+sample. The source checks pass 45 JS tests across both prototype directories and
+two Python ledger tests; changed source lint and formatting pass.
+
+A current coverage limit remains: call facts are part of the recovered IR
+facet. A function that exceeds graph capacity also loses these call records,
+even if a selected call-target view could fit. This is a reason to explore
+independent fact facets; it must not be mistaken for proof of no calls or full
+coverage on large functions. No full provider parity claim is made.
+
+The current producer also passes fourteen native JSON-format tests. The initial
+command compiled unrelated integration targets and a non-embedded CLI build,
+which replaced Cargo's mutable `target/release/kuna`. Its 181.103 wall / 172.430
+CPU seconds, 651.6 MiB peak and OOM 0 describe that broader compilation, not just
+JSON test execution. Future focused commands should select `--bin kuna` and
+`--features embed-specs`. The original embedded build restores from Cargo cache
+and has the same `64c6b3f...` digest.
+
+The first model launch after those tests correctly fails at `open_binary` with
+`engine_profile_mismatch`; it produces no target Evidence and is not a completed
+answer. Its rejected-trial costs are retained in `trials.md`. The producing
+boundary is now fixed by preserving an independent executable copy in a directory
+named by the full SHA-256, outside Cargo outputs. The model harness checks the
+explicit experimental engine pin before copying credentials or launching a model,
+and verifies the same bytes after the task. Changed/missing engines reject the
+comparison while retaining costs. Other provider trials keep this field unknown.
+Three regression tests cover missing/malformed pins, replacement and removal;
+a real driver invocation with a wrong pin rejects before output/profile creation.
+
+## Shallow outgoing references without decompilation
+
+Kuna already supplies native `xrefs --from`, including exact-instruction and
+owning-function queries. The shared `KunaReferenceFiles.ts` boundary now owns
+both directions, validates direction-dependent peer fields and query ownership,
+and preserves exact u64 endpoints and source-row occurrences. The old
+incoming-facts-only parser is removed; both experimental consumers use the same
+named query contract. Production incoming address-only queries keep their
+existing projection and bounded cache semantics.
+
+The experimental `references` method adds direction, explicit address/function
+scope, native kind filtering and fields. Incoming function scope is rejected;
+unknown outgoing function applicability, unattributed/excluded rows and unresolved
+indirect/discovery/runtime coverage remain explicit. Native source cache keys
+cover result-affecting query choices while scope, fields and pages reuse the same
+source. `reference-reads.mjs` owns protocol selection/projection; the resource
+owner and CLI/MCP adapters do not reinterpret native endpoint fields. Empty
+field selection now requests the existing always-retained identities, rather
+than being rejected without a format/resource reason.
+
+Real outgoing CLI probes return 396 VM call-reference rows in 205,432 bytes,
+versus one row/737 bytes for selected call site `0xf238b`. Four sequential probes
+(VM function/instruction and wrapper function/instruction) take 6.772 family wall
+/ 6.613 CPU seconds and 120.0 MiB peak. Each command takes about 1.6–1.7 seconds;
+these are native metadata-query measurements with warm uncontrolled file caches,
+not real-model speed/token results.
+
+Independent GNU objdump decoding over the exported VM symbol (`0xea6d0`, size
+`0x7e7e`) confirms all 396 `(origin,target)` pairs, 171 distinct exact targets,
+and 16 calls to `0x296c0`. It also finds 21 indirect calls, outside these
+known-target counts. In the wrapper, nine lifted machine call references compare
+with eight retained IR calls: machine `0x6534b -> 0x29370` is an omitted
+`__stack_chk_fail@plt` call. Its absence from optimized IR/C is not absence from
+the executable. No native analysis or C behavior is changed to repair that
+representation difference.
+
+The real Code Mode MCP verifier passes paging, identity-only fields, scope-cache
+reuse, exact sites, unknown applicability and local aggregation. It also captures
+the VM anew: C is available, IR fails with `atomic operation capacity exceeded`,
+and shallow references still work. This verifier takes 48.142 family wall /
+47.803 CPU seconds, 610.1 MiB peak; VM decompilation/source capture itself takes
+35.945 seconds. These are different requested capabilities, not an equivalent
+workflow speedup claim. The direct verifier passes the same reference contract
+without that VM decompilation (12.001 / 11.759 seconds, 256.8 MiB). Both verify
+cleanup and OOM 0. An earlier direct-verifier attempt incorrectly expected target
+metadata on an SDK input-validation error; the corrected verifier respects the
+SDK rejection boundary. That failed assertion receipt is retained.
+
+The exact focused boundary suites pass 38 tests, with a fresh strict production
+build; changed-test strict typechecking and 45 experimental JS tests also pass.
+Full lint/module boundaries and changed-file formatting pass. Repository lint
+warnings remain outside this change. The focused build/test scope peaks at
+3,030.6 MiB, below the 3 GiB early-stop line, with OOM 0. Two full `check:fast`
+attempts (including serial execution and Go runtime memory controls) reach that
+early-stop budget and are terminated before OOM; they are not reported as passed.
+The changed-test typecheck uses 70.1 MiB and standalone full lint 919.0 MiB.
+Full-repository typechecking and full upstream Kuna gates remain unverified.
+The [next question/oracle](reference-oracle.md) are committed before model trials.
+
+## Independent call and boundary-value facets
+
+Graph schema 3 removes embedded call records. An independent `atomic_calls`
+version-1 facet now carries every retained block-member CALL/CALLIND, target-input
+SSA identity, origin/block/opcode/dead status, call specs and boundary values.
+`atomic_values.rs` owns common native value interpretation. The call scan walks
+native block membership without allocating an operation vector for every block;
+its own call/input/value/text budgets do not depend on the 12,000-op graph cap.
+The default native path still does not collect either facet and C analysis phases
+are unchanged. All captures occur after the same C rendering.
+
+The bounded serializer retains fitting facets independently and preserves ordinary
+C/metadata. It tries the full document, graph without calls, calls without graph,
+then the base record with both reasons. This keeps existing graph availability
+when both facets individually fit but their combination does not. Facet contents
+are moved for these bounded alternatives rather than cloned; no reanalysis or
+clipped collection labeled complete is introduced.
+
+The JS owner validates each facet independently with shared ID/value contracts
+and row-wise admission. When both parse, call identities, origins, operands,
+outputs and boundary values must agree with the graph owner. Bad call facts do
+not erase a valid graph; a bad/oversized graph does not erase valid calls. Code
+survives either failure. `values` uses the complete retained graph when present,
+otherwise the explicitly scoped call-boundary set; absent IDs in that set do not
+prove absence from the native function. Defining operation identities may remain
+unreadable, and source signatures, source parameter ordinals, aliases and runtime
+binding stay unknown. `is_dead` is always retained on call rows, like an
+instruction decode status. CLI, SDK and both MCP adapters share these views.
+
+The new preserved engine is
+`e7d3f0cc8d8aae814bd6a2625a567d6aaad96c3fe2405a4f08dc8e065b851588`.
+Its full rebuild took 315.815 family wall / 315.305 CPU seconds, 2,119.4 MiB
+kernel process-family peak. Four focused native atomic-JSON tests pass, including
+both overflow directions, both-overflow C preservation and graph preference when
+the combined document is too large (95.981 / 95.631 seconds including test-target
+compilation, 626.8 MiB). The final CLI rebuild after tests is 26.203 / 25.952
+seconds, 492.7 MiB. It is copied outside Cargo outputs and pinned by full digest.
+All these runs verify cleanup and OOM 0; full upstream gates remain unexecuted.
+
+Real public MCP verification keeps VM C available, reports graph operation
+capacity failure, and now exposes 416 calls plus 1,294 boundary values. The call
+scan examines 21,349 operations over 1,229 blocks. It preserves 395 direct known
+targets and 21 unresolved indirect calls; all direct pairs match independent
+machine pairs except the omitted `0xf2493 -> 0x29370` stack-check call. All 21
+indirect origin addresses also match independent disassembly. Selected
+`0xf115c`/`0xf238b` calls target `0x296c0`; their fspec inputs remain separate
+annotation values. Repeated snapshots reuse the same handle and source, and an
+explicit unavailable graph read fails without hiding these retained facts.
+
+The VM source grows from 273,703 to 793,791 bytes to retain this new data; the
+wrapper grows from 202,206 to 208,083 bytes. Their ordinary records, including C,
+variables and line mappings, are identical to the prior capture. The wrapper's
+blocks/operations/values/coverage also remain identical. These are fidelity and
+source-volume observations, not model-token or speed results.
+
+The real reference/VM verifier passes in 49.471 wall / 49.130 CPU seconds,
+615.8 MiB. The existing cross-function call/input verifier passes in 8.377 /
+8.094 seconds, 292.9 MiB; encoded Pragma/parser C/graph checks pass in 12.403 /
+12.195 seconds, 335.0 MiB. All verify cleanup and OOM 0. The updated contract
+suite passes 47 JS tests, including independent facet failure, cross-facet
+conflicts, input-zero identity and boundary-only value reads. `check-spec` passes
+in default lenient mode, lint and changed-file formatting pass, and the patch
+applies forward to the pinned upstream revision and reverses from the clone.
+Full repository typechecking retains its previously recorded resource limitation.
+The [boundary question/oracle](boundary-oracle.md) are fixed before model runs.
+
+The subsequent real-model pair passes that oracle in both calling modes. Each
+uses one VM analysis and the same retained function record; neither invents a
+complete graph from the available call-boundary values. Source digests, target
+and preserved-engine pins, selected machine checks, cleanup and OOM-zero receipts
+verify. See [whole-task costs](trials.md): the capability survives real model use,
+but a single mixed-context-cost pair does not establish general efficiency.
+
+## Compact counts from the validated call owner
+
+The following API-only change keeps the preserved engine and native source
+format unchanged. Snapshot call metadata includes counts by recovered opcode
+and known/unknown native target, plus call coverage. The owner computes these
+once after validation, before the shared CLI/SDK/MCP views. Counts include dead
+rows and do not infer target knowledge from CALL versus CALLIND. Available empty
+sets have zeros; unavailable sets have no counts. Selected call reads do not
+change this whole-facet summary or require a new analysis.
+
+The focused suite passes 49 tests, including known indirect/unknown direct
+targets, dead rows, immutable summaries and empty/unavailable distinction.
+Both real MCP adapters verify the wrapper's eight direct calls and parser's
+28 direct/five unresolved indirect calls while preserving the existing
+cross-function checks and validating advertised schemas after SDK conversion.
+Code Mode verification takes 29.263 family wall / 21.548 CPU seconds, 283.9 MiB
+kernel family peak; direct takes 32.893 / 22.781 seconds, 280.6 MiB. Both have
+verified cleanup and OOM 0. These are validation runs, not a controlled speed
+comparison with previous verifier timings. An owner replay of the prior
+digest-verified VM source yields the expected 395/21 distribution; it is not
+relabeled as a fresh provider or model run. The identical boundary question and
+oracle are retained for subsequent real-model comparison.
+
+That comparison now passes in both modes. Both consume the compact counts and
+read just the two selected calls, reusing one VM analysis. All native VM function
+records match the preceding pair and all retained sources/digests verify. Direct
+has lower observed task costs than Code Mode in this sample; the before/after
+results remain mixed. [trials.md](trials.md) records cumulative/cached/uncached
+tokens, model responses, elapsed time, CPU and process-family memory, including
+the slower Code Mode result. No native engine or analysis-speed improvement is
+claimed for this shared owner metadata change.
+
+## Tagged cleanup ownership regression
+
+Source inspection finds that the experimental owner awaits but ignores
+`KunaTargetCommands.close()`'s tagged `Result`. On error it would clear its state
+and let `AtomicSession` drop the owner while claiming a successful close. The
+SDK verifier reproduces this before the fix: an injected `ProviderCleanupError`
+does not reject close. Its fallback cleanup still removes the real owned state;
+the original failing result is retained as `cleanup-before.json`.
+
+The owning boundary now uses the existing `requireResult` projection before
+closing its cache root or clearing state. The existing session queue therefore
+retains the owner on failure. Both close and target replacement report
+`cleanup_incomplete`, preserve the staged file identity and original lease, and
+succeed on retry; the file is then absent. MCP's open/close error adapter now
+preserves context and resource details rather than dropping that evidence. The
+CLI already propagates the thrown error as a failed command. No alternate
+cleanup owner or downstream retry workaround is added.
+
+`verify-cleanup.mjs` runs against real provider reads and resources, injecting
+one tagged failure per close/replacement case. `verify-cleanup-mcp.mjs` injects
+one explicit test-only failure in an isolated server, then verifies public
+Code Mode and direct error metadata and successful retry. These are controlled
+boundary failures, not a claim that the real engine failed to stop. The SDK
+check takes 1.730 family wall / 1.567 CPU seconds, 130.4 MiB kernel peak; MCP Code
+Mode takes 1.931 / 1.639 seconds, 200.0 MiB; direct takes 1.730 / 1.489 seconds,
+192.8 MiB. All verify process cleanup and OOM 0. The original failing verifier
+takes 1.226 / 0.985 seconds, 122.7 MiB and also verifies fallback cleanup/OOM 0.
+The 49 focused JS tests, lint and formatting pass. This lifecycle-only change
+follows the recorded model pairs; no new model token or speed claim is made.
+
+## Callable bounded definition projection
+
+The next native exporter retains a version-1 `atomic_projection` independently
+of graph version 3 and call version 1. One checked native membership scan owns
+call roots and an optional index of at most 65,536 operation keys; exceeding the
+index budget disables the projection without discarding calls. Full-graph row
+capacity is checked before rendering its rows. Full and selected facts share
+one operation/value normalizer, including exact identities, indexed operands,
+outputs, phi predecessor edges, flags and display. Default non-atomic analysis
+and C generation are unchanged.
+
+All recovered CALL/CALLIND operations are retained as projection roots, followed
+by backward operand definitions in breadth-first order. The projection bounds
+4,096 operations, 12,288 values, 16,384 inputs and 2 MiB text. Too many roots or
+another admission failure makes the facet explicitly unavailable. Omitted
+definitions retain exact IDs and operation-budget/outside-membership reasons.
+A fitting full graph omits its redundant projection; an encoded-overflow graph
+restores the fitting projection. Facets are moved through bounded alternatives,
+and a valid C/call record survives projection failure. There is no repeated
+decompilation or clipped collection labeled complete.
+
+The JS boundary shares operand/value validation and query indexes between full
+and sparse views. It checks root reachability, exact frontier membership,
+call/value agreement and phi metadata without inventing a CFG. In the absence
+of a full graph, conflicting projection facts do not erase independently valid
+calls. `snapshot.facets.operations` and `facets.values` expose their scopes;
+selected definitions/uses and slices work over the retained set. Uses remain
+selected-only, CFG/controller queries retain their graph error and Evidence ID,
+and slice missing definitions keep their native reasons. A missing projection
+preserves the original graph failure instead of hiding it behind a generic
+not-captured error. All adapters use this owner.
+
+Coverage returns counts instead of global omitted-ID inventories, at most eight
+160-character issue summaries, full issue counts and omission metadata. Complete
+native coverage/frontier details remain in source Evidence. Native operation
+rows retain `is_dead` with their identities; constant summaries add `value_id`
+and `input_index`, preserving exact offset/width semantics. No original-signature,
+arbitrary-width computation, memory-alias or runtime proof is introduced.
+
+Preserved engine SHA-256:
+`a0685486518e09d3c65f756325a7e9fed8df123a2a988aca2972a72335ce8edc`.
+The same one-job/embedded-spec build takes 309.805 family wall / 309.523 CPU
+seconds, 2,099.5 MiB kernel family peak. Six focused native JSON tests pass,
+including projection restoration and independent overflow (99.752 / 98.662
+seconds with test compilation, 626.9 MiB). The final CLI build reuses artifacts
+(0.320 / 0.146 seconds, 28.8 MiB), leaving the preserved digest unchanged.
+
+Real SQLite VM public reads expose 4,096 operations, 7,469 values and 326
+unexpanded definitions, while the complete graph remains unavailable. Source is
+4,008,032 bytes, inside the unchanged 8 MiB public budget. Every selected operation
+and value equals the earlier 17.8 MB diagnostic capture; ordinary C/metadata and
+the complete call facet also equal it. An independent BFS over that retained
+full graph produces exactly the same operation order and frontier. The extended
+`measure-native-projection.py --verify-capture` reproduces these comparisons.
+This is producer-fidelity evidence, not independent machine/runtime equivalence.
+
+Both public MCP adapters read the selected PHI definitions and slices from one
+VM source. Code Mode verifies unavailable controllers preserve the source ID.
+The corrected Code Mode verifier takes 52.706 wall / 47.550 CPU seconds,
+597.4 MiB peak; direct takes 39.696 / 39.418 seconds, 592.5 MiB. The first
+Code Mode verifier incorrectly expected INDIRECT definitions; independent source
+inspection shows MULTIEQUAL. Its 37.070 / 36.781 seconds, 593.3 MiB failed
+assertion is retained, then the verifier is corrected without changing native
+facts. These scripted runs are validation costs, not an adapter speed comparison.
+
+Small-function cross-call checks pass (8.476 / 8.204 seconds, 293.6 MiB); all three
+complete function records equal the prior exporter. Encoded Pragma/Parser checks
+pass (13.712 / 13.507 seconds, 361.5 MiB): Pragma retains 3,627 projected operations
+after graph encoding overflow, while Parser keeps its full 5,164-operation graph
+without a duplicate projection. Zlib control/phi regression passes (10.893 /
+10.700 seconds, 286.3 MiB). Real CLI reads verify both selected PHIs and repeated
+snapshot/source identity (37.367 / 37.174 seconds, 527.1 MiB).
+
+The real VM MCP cache benchmark observes cold snapshot wall 36,448.8 ms / family
+CPU 36.425 seconds, then warm 40.2 ms / 0.041 seconds with the identical handle
+and source. Cumulative family peak is 590.1 MiB, an upper bound on isolated warm
+phase memory. Its complete run is 37.667 / 37.492 seconds. This is same-lease
+capture reuse, not cross-session persistence or a model-token result; OS caches
+remain uncontrolled. All resource runs above verify cleanup and OOM 0.
+
+The focused JS suite passes 53 tests; lint/format, default lenient `check-spec`,
+Python compilation and patch forward/reverse checks pass. Full upstream corpus,
+stages and workspace gates remain unexecuted; the patch is not upstream-ready.
+No whole-repository typecheck pass is claimed beyond the previously recorded
+resource limitation. The [PHI-format task/oracle](projection-oracle.md) are fixed
+before real-model launches. No model benefit is assumed from these smaller facts.
+
+## Named reference discovery and input schemas
+
+The first PHI model pair completes correctly but exposes a documentation boundary:
+direct help displays `facts_*` names while lookup only recognizes raw method
+substrings. A multi-name query returns no matches and causes a full-reference
+fallback. Registration and help now share one explicit name map, with canonical
+identity separate from presentation. Exact lists preserve caller order,
+deduplicate names and retain unmatched terms. Topic/all-contract lookup remain;
+ambiguous labels fail instead of choosing by catalog position.
+
+The real client verifier also catches that plain `z.toJSONSchema` defaults to
+output semantics, making defaulted `offset`/`limit` falsely required in advertised
+input schemas. Reference generation now explicitly selects `io:input`. Converted
+schemas are frozen and weakly cached by schema identity; a replacement schema
+invalidates the conversion, while description/presentation is read separately.
+The documentation module removes the adapter rename pass. No target analysis,
+live-result caching or native-engine change is involved.
+
+The shared suite passes 55 tests. `verify-discovery.mjs` checks both real SDK
+catalogs and reference responses without opening a target, compiles every catalog
+and all fourteen reference schemas with Ajv2020, and validates the same
+omitted-default requests against named reference/direct contracts. It proves the
+six-name query matches all requested contracts without a miss. The all-schema
+verifier takes 1.936 family wall / 1.760 CPU seconds, 138.8 MiB kernel peak,
+cleanup verified and OOM 0. The earlier six-schema probe takes 1.628 / 1.449
+seconds, 128.9 MiB. Its original 1.730 / 1.487 seconds, 128.1 MiB failed
+omitted-default check remains recorded. Six contracts occupy 10,835 Code Mode /
+10,360 direct bytes, versus 21,746 / 20,699 for all fourteen. Bytes do not prove
+token or time savings. The same PHI question/oracle are retained for the next
+actual model pair.
+
+## Wide native operand relations
+
+A retained-source replay exposes a whole-row cost: VM PHI
+`0xea998:14649` has 156 inputs and 156 definition edges. Its normalized old
+operation is 44,447 JSON bytes, and a default one-node slice returns 44,980 data
+bytes. Real QuickJS returns `output_budget` while preserving the source ID.
+This replays real producer facts through the shared parser/executor, without
+a fresh native analysis or model call (`wide-phi-before.json`). Explicitly
+requesting only `inputs` already fits; the gap is default size and lack of
+independently selected/paged operands, not inability to obtain the data at all.
+
+`relations kind:operands` now owns slot-level paging and optional input-index
+selection. Snapshot + operation + input_index identifies the relationship;
+value identity, native definition and exact phi edge are separate fields. It
+retains constants, function inputs and nulls that definition edges cannot cover.
+Requested out-of-range slots of retained seeds are absent, while unretained
+seeds stay explicit/unknown. Seeds and selectors deduplicate in caller order;
+total counts filtered rows before paging. Full graph and projection share this
+owner; diagnostic SSA rejects the unsupported relation with source context.
+
+Paging counts existing relation groups before materializing selected rows,
+avoiding a complete flattened relation copy. Native operation defaults are
+compact summaries with exact input/definition/constant counts; detailed fields
+remain selectable. Repeated value/block identity lookups deduplicate at their
+shared read boundary. A discriminated contract replaces the prior runtime-only
+relation refinement, so advertised schemas also enforce seed types and prohibit
+input_indices on other relationship kinds. No native rebuild, higher native
+capacity, new method or additional authority is involved.
+
+The shared suite passes 57 tests; changed JS lint has zero warnings and formatting
+passes. Both real SDK catalogs and all reference schemas compile; selected
+operand inputs and invalid selector applicability agree with runtime validation.
+That discovery run takes 7.443 family wall / 4.928 CPU seconds, 141.8 MiB peak
+including charged file cache. The real Code Mode VM verifier passes ten calls
+in 54.327 / 47.069 seconds, 597.6 MiB peak. Its default slice fits, selected
+slots preserve exact native facts, and explicit all-input reads still work.
+Both runs verify cleanup and OOM 0. This first public run precedes the final
+identity-deduplication adjustment; subsequent direct/model reads cover it.
+Scripted bytes and costs are not model-token savings or an adapter speed claim.
+The subsequent direct verifier passes all ten calls, including duplicate-value
+deduplication, in 39.385 wall / 39.163 CPU seconds, 591.3 MiB peak, with cleanup
+verified and OOM 0. The different scripted read paths/host state do not isolate
+adapter costs. The [wide-operand oracle](operands-oracle.md) fixes the next seeded
+real-model task before launch; it is not a before/after of the PHI-format task.
+
+## Static method index
+
+The wide-operand pair exposes a discovery cost: Code Mode asks four times for
+help before using the same seven fact requests as direct. `reference view:index`
+now returns the same fourteen canonical/display names and descriptions without
+constructing schemas, return contracts or examples. `view:contracts` preserves
+the existing default and exact-name/topic behavior. Both presentations share one
+named documentation contract/owner and the API's registry; no analysis change or
+engine rebuild is involved. An index is static declared support, never live
+provider capability. Runtime facets remain authoritative.
+
+The shared suite passes 58 tests, including a getter that proves an index does
+not access an unrequested input contract. Changed JS lint/format and both real
+SDK catalogs/reference schemas pass. The first discovery probe takes 5.284 family
+wall / 4.028 CPU seconds, 137.6 MiB peak, cleanup verified and OOM 0. Code Mode's
+index is 7,212 JSON bytes versus 24,010 for all contracts; direct is 7,240 versus
+22,939. These bytes are static discovery output, not demonstrated token/time
+savings. A subsequent focused check and real probe cover moving the input schema
+into the documentation owner and unifying presentation construction. The same
+wide-operand question/oracle are retained for a new real-model pair.
+
+The final real SDK probe passes in 4.380 wall / 3.807 CPU seconds, 141.4 MiB peak,
+cleanup verified and OOM 0. Both subsequent real-model answers satisfy the
+unchanged oracle. Code Mode uses index plus one exact contract query, reducing
+its discovery lookups from four to two. Whole-task costs remain mixed; all
+attempts and limits are recorded in [trials.md](trials.md).
+
+## Fact granularity versus computation granularity
+
+The eight successful real-model VM captures using the preserved `a0685486...`
+engine each retain 4,008,032 bytes, including 126,519 bytes of reconstructed C
+that the selected-operand models never read. Fresh-lease native request wall
+ranges from 36.702 to 53.124 seconds. A separate failed first attempt hits the
+120-second timeout before one successful capture; its cause remains unknown.
+These are fresh private native caches, not controlled OS-cold samples. Same-lease
+warm source reuse remains separately measured above.
+
+Source inspection explains the current computation boundary: the project core
+drives whole-function decompilation, renders C and extracts metadata, then
+collects independent call/graph/projection facets from the live function. The
+new slot atom reduces selected read/serialization scope, but does not implement
+selected-slot native analysis. The complete VM CFG is still unavailable and
+arbitrary definitions outside the retained call-rooted projection cannot be
+expanded by a fact read. Provider parity and general complex-software superiority
+remain unestablished.
+
+At that checkpoint, pipeline/render/metadata/export costs were not separately
+profiled. The [subsequent native computation study](native-compute-study.md) now
+measures them: VM drive about 34 seconds, C rendering 0.22 seconds and projection
+0.03 seconds. Skipping C is a small opportunity for this workload. An offline
+lossless encoding probe also puts the earlier full 17.8 MB diagnostic record
+inside the unchanged 8 MiB transport. The [subsequent codec study](native-graph-transport-study.md)
+now implements and verifies this through both public experimental MCP adapters,
+including complete decoded Evidence and shared text-budget ownership. Actual
+guard/control model behavior is now checked in two real-model pairs. Model
+comparisons share the same computation/fact owners, avoiding a capability
+difference between adapters. The [switch extension](switch-study.md) adds an
+independent native table facet with exact labels and row/edge mapping, selected
+queries and a verified 2 MiB fallback that retains cases without a full graph.
+Its final engine is `a9ca8a8ac224936afb08a9d4be9c1225feb69473ad9f35764e8d1c4f04875b5b`;
+the fixed case/default model question is separate from the earlier guard pairs.
