The session remembers a graph that overflowed, so later call queries fail at once instead of repeating the whole-program walk. The graph is cached for the selected target and executable profile within one session. Xref reuse is an LRU charged by source bytes plus metadata, limited to 16 MiB and 128 entries; at most eight distinct native xref queries may be pending. Reference commands run one at a time per session and share the provider's foreground budget with single-function decompiles. An unproven process stop retains its admission slots until cleanup succeeds. Concurrent callers share work, individual cancellation releases only that waiter, and the last departing waiter cancels its producer and receives any unproven cleanup. Session close aborts and drains producers, releases parsed caches and retries any retained process/file cleanup.
+REA parses the graph as Kuna writes it, like the string scan, so the graph has no fixed size: a 53 MB Raycast binary produces 157 MB (180k functions, 773k edges), which REA retains in about 93 MB after a whole-program walk of about a minute. Unrequested bodies are refused before any of their text is assembled, and edges are indexed as they arrive, so retained rows and their indexes are admitted against live heap headroom. Xref JSON admits at most 16 MiB before parsing.

 Evidence includes only selected addresses or dossier neighbors, the producing JSON's SHA-256/byte count, coverage and relevant function facts; unrequested program-wide JSON and instruction text are omitted. Reference caches are in memory and expire on close: a fresh CLI process or MCP server rebuilds them. A first call query therefore costs a whole-program reference walk even when a C export is warm. These operations do not establish full Ghidra/IDA feature parity.

+[#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.

+| 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:

+python3 experiments/analysis-efficiency/electron-cancellation-oracles.py \

+# 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.
+
+## Main integration on 2026-10-15
+
+The measured V2 checkpoint is
+`d32547f9ac7769049a8ee6fbc8a27abcb2285a54`. Main advanced during the trials;
+merge `5f0b1fa47ffdf25b3775d87c2e07aea6cff26f31` integrates pinned current main
+`2202e3f0ba556d40cc6e598df1ecbdf1eda56c13`, including independent semantic
+value/lifecycle fixes. Historical cohorts remain valid for their pinned backend,
+not measurements of the later integrated backend. Integrated normal/interruption
+export/view controls and the complete focused/static/docs gates are recorded
+separately below and in JSON when executed. No agent pilot rerun or universal
+token/latency benefit is inferred from that source update.
+
+Integrated checks passed: all **101 focused cases in six files**, full static
+checks, generated docs/metadata, five consistency cases and test discovery.
+The combined gate took **247.955 s wall / 247.425940 s CPU / 4,303,970,304 B**
+peak cgroup memory; no OOM and verified cleanup.
+

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

+
+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.
