fix(javascript): escape repeated prefixes in front of copied-slot selections

Member-mutation normalization keeps any path carrying a copied-slot selection
exact and never prunes it, but the repeated-prefix rule only escaped a
repeating prefix when its projected origins proved it unprunable. A self alias
in front of a spread selection, such as `const t = { ...e.opts }; e = e.value;
consume(t)` with a parameter `e`, therefore grew `[value, value, ..., opts,
<selection>]` without bound until the worker heap was exhausted. The owner of
both rules now reports a selection-carrying path as never pruned, so the
prefix escapes once as designed.

Obsidian's bundled pdf.js viewer (Fluent's FluentDateTime constructor)
exhausted a 6 GB heap in 36 s and now completes its semantic phase in 0.9 s.
Semantic IR is byte-identical on the 151 comparable real files.

 Keep proof of ownership separate from validity, editability, and readiness. Malformed owned data may still be safely removable. Unresolved identity or applicability must remain unknown rather than be treated as absent, foreign, or aligned.
 
+For lifecycle changes, follow [ownership and completion invariants](docs/tool-design.md#own-the-lifecycle) and select the applicable [lifecycle regressions](docs/testing.md#lifecycle-regressions). Include late handshakes, cancellation during final cleanup, mixed child outcomes, and cleanup retry where those stages exist; active-execution cancellation alone does not cover finalization.
+
 Assess brittleness in touched code during implementation, debugging, review, and maintenance. Fix the producing representation or ownership rule before adding downstream repairs. Normalize once at the owning boundary using format-aware parsers. Remove superseded representations, aliases, wrappers, and redundant tests after verifying affected consumers. Introduce abstractions only when they remove observed complexity.
 
 When fixing a bug, inspect the producing boundary and affected consumers for duplicated interpretation or unclear ownership. Complete any directly related refactor in the same change and remove superseded code. Passing regression tests alone does not establish that the brittleness is resolved. If related cleanup remains, explain what remains and why.

+well as persistent engine sessions. Use the existing provider contracts;
+providers need not expose identical state machines.
+
+- Keep target admission, provider readiness, active work, observed process exit,
+  and resource release separate. A valid process handle, successful launcher,
+  or selected target establishes only its own fact. Publish available identity
+  and exit observations even when launch fails; retain unknown ownership.
+- Authenticate and capture identity through the same boundary on initial and
+  recovery handshakes. Bound abandoned unauthenticated listeners where the
+  protocol permits it; that deadline must not expire authenticated idle sessions
+  or long-running native work. Listener expiry does not prove target closure.
+- Shared startup has one producer and independently cancellable caller waits.
+  Keep it running while any caller still needs it. The final departing caller
+  waits for owned cleanup and retains its failure. Provider closure is distinct
+  from caller cancellation. Retained cleanup capabilities block replacement;
+  derive readiness from the current startup's completion and live connection.
+- For cancellable observations, carry cancellation through result consumption
+  and awaited cleanup. Before returning success, check the signal after the
+  last awaited finalization step.
+  Retain collected observations under typed cancellation. Preserve an existing
+  primary failure and let incomplete cleanup retain its own classification.
+  Client cancellation alone does not prove native work stopped.
+  For atomic publication, document the cancellation cutoff and preserve any
+  committed output's publication receipt.
+- Release only owned resources. Attaching owns a connection or session unless
+  the provider contract explicitly establishes target ownership. A helper exit,
+  missing reply, or missing PID does not establish target exit.
+- Retain successful child cleanup and retry only unresolved children, including
+  when close options change. Preserve observed child failure or activity when
+  another child's health is unavailable; idle plus missing coverage stays
+  unknown.
+  Bind cleanup failures to their exact resource owner. Resolve current cleanup
+  uncertainty only after that owner confirms release, while preserving the
+  original failure and completed observations. Later failure composition must
+  report only resources whose cleanup remains unresolved.
+- Await one-shot cleanup without discarding the completed result or primary
+  diagnostic. Preserve partial observations, remaining resources, and the cleanup
+  owner's recovery instructions. CLI adapters should reuse
+  [`finishAnalysisCommand`](https://github.com/morluto/rea/blob/main/src/cli/finishAnalysisCommand.ts) where its contract
+  applies rather than duplicate close/finally handling.

+# Interrupted application processing: applicability and Evidence
+
+Tracks #3948 under #4027. Measured baseline:
+`c7f6b8bad1a34d5efb30ff2a017672dea1fcdabb`.
+
+The question is which processing phases remain unavailable after a source
+interruption, while keeping native inventory and already collected facts.
+Native identity and provider linkage must stay independent of application-wide
+partial coverage. This is static artifact analysis; no target application or
+native provider runs.
+
+## Observed failure and correction
+
+The interruption producer previously attached one generic failure to every
+remaining relevant file. Graph projection interpreted it as JavaScript AST work.
+Real Joplin reproduced an `analyze-javascript-source` / `ast-static-analysis`
+unavailable scope on keytar's native binary and on unvisited package, HTML and
+source-map files. Public CLI/MCP controls reproduced the same applicability
+problem. Deterministic cancellation before native metadata additionally produced
+a phantom JavaScript semantic module for the binary.
+
+The producer now records the applicable operation/authority and whether the
+phase was entered. `analysis_status: interrupted` includes worker startup and
+does not imply parsing completed; `not-started` identifies unvisited phases.
+Native add-ons need no post-inventory source-processing phase, so neither interrupted
+nor caller-excluded native files acquire AST scopes or semantic modules.
+Actual JavaScript failures, structured-file unknowns, caller selection and byte
+identity remain available. The graph consumes these produced facts.
+
+The AST-only unavailable Evidence helper is replaced by an explicitly typed
+static helper. Normal package/JSON/map gaps also retain their artifact-byte
+authority. Per-file progress uses the same applicability owner: JavaScript keeps
+its source phase, and metadata uses `process_javascript_artifact_metadata`.
+Remaining parsers do not run after interruption. Failure sharing is limited to
+five applicable phases during one interruption; no persistent cache is added.
+
+A second review found the alternate full-analysis semantic builder still
+created modules for every excluded file kind. An actual filesystem-producer
+regression on revision `323fae8cbf3e36677bcb7b22ba31fa1a7e3c5cd4` reproduced
+phantom native/JSON/HTML/package/source-map modules, while selected and excluded
+JavaScript were positive controls. Semantic applicability now belongs to the
+shared `recordUnavailableFile` projection entry point, before retaining limits,
+nodes, roots or unknowns. Three duplicate caller checks are removed. Both full
+and incremental construction use this boundary; actual excluded JavaScript
+continues to carry source-bound unknowns and partial semantic coverage.
+
+## Real input and reproduction
+
+Use the [official Joplin v3.7.21 acquisition and extraction instructions](https://github.com/morluto/rea/blob/c7f6b8bad1a34d5efb30ff2a017672dea1fcdabb/docs/verification/javascript-native-handoff-identity-2026-10-15.md).

+ASAR SHA-256 is
+`767df409b18effe60421fbefcca873de237c7e813eac744ecdeebbc5e825a33a`.
+The 6,324-file inventory includes 46 unpacked entries. Both cohorts stage all
+three native companions; the other 43 unpacked entries remain unavailable.
+
+Build with pinned Node 24.18.0/npm 11.16.0 and locked dependencies. The extended
+existing verifier also runs against the baseline runtime; copy the verifier and
+`scripts/lib/javascript-file-scope-oracle.mjs` from the fixed revision into a

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

+
+The full-catalog alternatives and per-query samples are preserved in JSON.
+Native content identity, observed byte provenance, source selection and handoff
+provider Evidence remain equal. Corrected global provenance changes derived
+parent/trace identities; null partial-Evidence subjects remain null. Both final
+runs have exact CLI/MCP native-trace parity and match the earlier post-fix
+controls in every recorded non-timing field.
+
+The whole verifier includes input hashing, analysis, three native trace rounds,
+applicable structured queries, export, CLI parity and tokenization. Every heavy
+run uses the preserved [resource observer](https://github.com/morluto/rea/blob/b3bdabab694af1f9801eff7caf75001b92314a58/experiments/analysis-efficiency/resource-run.py):
+one CPU, 8 GiB hard cap, 6 GiB early stop and no swap. Cgroup peaks include charged
+file cache, not summed RSS. Counters are observed at payload exit while the
+observer remains alive, not final whole-scope counters. Completed runs verify
+owned cleanup and report no OOM.
+
+Each MCP process is fresh, but input hashing warms its file cache. Build/OS caches
+and shared-host scheduling are uncontrolled. First and repeated retained-query
+wall samples remain separate; isolated query CPU/memory are unmeasured. An
+earlier fixed timeout took 150.173 s wall / 119.468013 s CPU; its exact unchanged
+runtime repeat took 58.827 s / 58.482996 s, with identical non-timing facts,
+Evidence and BPE. Both receipts are retained. The final default control also took 186.085 s wall / 142.371100 s CPU; its
+unchanged-runtime repeat took 62.651 s / 62.240964 s with identical non-timing
+results. The slow final row remains reported. Attribution remains unresolved;
+these runs establish no speedup or performance-equivalence bound.
+
+The stricter post-review verifier reruns also passed without changing production
+code: timeout 162.645 s wall / 125.876114 s CPU / 2,809,643,008 B peak; default
+control 61.367 s / 60.970077 s / 2,526,949,376 B. Both preserve the original final
+analytical fields, identities, coverage and BPE exactly; only timings and the new
+explicit oracle-input field differ. These additional receipts do not replace the
+slower rows above.
+
+After centralizing semantic applicability, both real public controls passed again:
+timeout 60.443 s wall / 59.970344 s CPU / 3,078,295,552 B peak; default control
+63.574 s / 63.177884 s / 3,189,719,040 B. Analytical results, identities, coverage,
+BPE and exact CLI/MCP parity remain unchanged. JSON identifies the runtime and
+verifier source manifests for each cohort and keeps all earlier receipts.
+
+Static `cl100k_base`/tiktoken 0.12.0 projections include the selected or complete
+name/description/inputSchema catalog, requests and structured Evidence or parsed
+text errors. Complete-tool-reply alternatives include MCP text/structured
+duplication. The selected two-tool catalog is 5,570 BPE; the complete projection
+is 195,522. Output schemas, host rendering/replay, notifications, model reasoning,
+final answers and billing are unmeasured. Repeated rounds, export, CLI parity,
+tokenization and exported-parent diagnostics are validation overhead outside the
+defined task tokens but inside resource receipts. Removing unsupported claims
+from the incorrect timeout baseline earns no efficiency credit.
+
+## Verification and limitations
+
+The initial production fix had 49 distinct passing cases across eight files. The initial
+pre-progress-cleanup seven-file selection passed 44/44. After progress cleanup,
+the same selection passed 43 and hit the existing 30-second test deadline in one
+native identity case; an unchanged two-file rerun passed both native cases and
+five public CLI cancellation cases. The original deadline was not increased.
+The runtime verifier collects interruption-bearing scopes; separate regressions
+cover native caller exclusion and malformed structured data. Source selection,
+malformed structures, actual worker resource constraints,
+retained large partial observations, cancellation/publication/cleanup, native
+identity and both public adapters remain covered.
+
+The first review found that the real verifier previously accepted any non-JavaScript
+operation with artifact-byte authority and ignored phase-entry status. The
+scenario now supplies exact operation/status expectations independently of the
+production phase map. Six additional oracle cases use the actual retained
+Joplin snapshots and reject wrong metadata operations, entered or missing
+statuses, and absent or conflicting gaps. They passed, bringing the distinct
+coverage to 55 cases across nine files. The production implementation did not
+change during this review correction.
+
+After the shared semantic-boundary correction from the second review, 78
+distinct cases passed across ten files: the nine-file selection passed 65/65,
+and the original root reconstruction file passed 13/13. This includes the
+alternate-builder owning test file's 23 cases. The new producer-boundary
+regression checks both construction paths, all five excluded metadata/native
+kinds, and selected/excluded JavaScript controls. Real Joplin controls exercise
+the public incremental workflow; the alternate full-builder path has filesystem
+boundary verification rather than a separately measured real-app workflow.
+
+Recorded attempts also include the verifier's initial non-null-subject assumption
+and an invalid top-level semantic-module-path absence check. Both were corrected
+before their assertions were used as proof. Corrected cancellation reproduction
+shows the actual native AST scope and phantom module on the baseline. Final
+source and execution-driver versions, source pins, input digests, prior attempts
+and resource receipts are in the [compact JSON record](javascript-interruption-applicability-2026-10-15.json).
+
+Before review, `npm run check && npm run docs:check` passed, including five consistency
+tests: 165.553 s wall / 150.247257 s CPU /
+4,232,491,008 B peak cgroup memory, clean owned exit and no OOM.
+The first full check stopped on a 172-line test callback exceeding the 150-line
+rule. A named assertion helper now shares scope lookup across all four public
+results; the strengthened six-case file passed again before the final gates.
+After the review correction, the full static/docs gate passed again, including
+the five consistency tests: 111.395 s wall / 110.979710 s CPU /
+4,347,125,760 B peak, with clean owned exit and no OOM.
+After centralizing semantic applicability, the final full static/docs gate also
+passed, including five consistency tests: 117.636 s wall / 117.194118 s CPU /
+4,263,153,664 B peak, clean owned exit and no OOM.
+
+At the initial PR revision, 36 CI checks passed; macOS `hdiutil create` failed
+while creating its DMG fixture before REA verification, also failing the aggregate
+check. No Apple fixture/workflow code changed. That attempt provides no passing
+Apple runtime evidence.
+
+Live Electron/application execution, real native-provider behavior, other-platform
+runtime coverage and hosted-agent costs are **NOT_ENOUGH_INFO**. The verification
+does not claim them.
