-The producer now records the applicable operation/authority and whether the

-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

-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.

-| Timeout        |                                  21,136 → 20,161 |                              36,468 → 34,471 |
-| Native control |                                  11,776 → 11,720 |                              17,738 → 17,632 |
-
-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.
