+# Browser and Electron code-mode pilot
+
+This isolated experiment asks whether model-written JavaScript composition of
+the same REA tools improves actual investigation outcomes, model usage and
+latency. It does not add a production tool, change a provider or authorize
+new target execution. This directory is outside the package's `files` list.
+
+See [the measured pilot results](results-2026-10-15.md) before interpreting
+this harness as evidence of a code-mode benefit.
+
+## Decision and preregistration
+
+Primary comparison: the best supported current REA workflow, including source
+selection, summaries and retained views, versus the **same** backend, artifacts,
+tool allowlist and analyst question accessed through client code execution.
+The model writes its own loops, filtering and joins; canned author-written
+projection scripts are not credited as agent code-mode results.
+
+Requested model: **gpt-5.6-terra**, reasoning **high**, local Codex CLI. Preserve
+the requested alias and separately observe what the client actually does.
+Do not silently substitute another model or interpret a feature flag as proof
+of execution mode. Existing REA experiments found executor use in trials
+labelled direct, and direct MCP calls in trials labelled code-mode.
+
+Hypothesis: code mode reduces total and uncached model input plus end-to-end
+latency for questions requiring multiple dependent reads or aggregation,
+without reducing claim correctness, provenance or coverage honesty. Simple
+lookups may instead cost more because of discovery, code generation and
+debugging. A null, negative or inconclusive result is valid.
+
+Use shipped applications and real public-web observations, not CTFs, synthetic
+applications or source-owned demonstration targets in the scored cohort:
+
+- Obsidian 1.14.4's published Electron ASAR, pinned by the existing corpus
+  acquisition and artifact digests; static investigation only.
+- A frozen capture of the actual public Excalidraw application in an owned
+  empty-profile browser. Reuse the exact recorded bytes across treatments;
+  do not compare independently changing live sessions as equivalent inputs.
+
+Questions cover a small exact lookup, a cross-record/IPC or source join,
+network aggregation, and a claim the available evidence cannot establish.
+Score exact requested facts and evidence-supported unknowns. Do not count
+keyword mentions, fluent prose or a smaller response as correctness.
+
+Before scored trials, establish a native treatment-validity gate: direct runs
+must contain actual direct MCP calls and no JavaScript executor. That gate
+failed with Codex 0.161.0: the requested direct configuration invoked `exec`,
+which failed when its host was disabled. The enabled host successfully called
+the same session tool. These are retained infrastructure observations, not
+scored application comparisons.
+
+The scored pilot therefore uses a common **external JSON action protocol**.
+The same Codex CLI samples one action at a time, with native tools disabled;
+the same REA SDK client executes each action. Direct actions invoke one
+production tool; code actions run model-written synchronous JavaScript in
+QuickJS and expose the same production tools through `rea.call(name,args)`.
+Both can discover original contracts on demand. No author-written answer
+projection is inserted into either treatment. Any observed native tool call
+invalidates the controlled trial. This measures organization under this
+protocol, not native Codex direct-MCP versus native Codex code-mode latency.
+
+Every model round starts a new CLI invocation with the full common question
+and accumulated action/observation history. Count all actual usage, including
+repeated client instructions and generated JSON escaping. Common client
+startup and context replay can amplify a difference in model round count;
+this is a limitation of the pilot, not a production speedup claim.
+
+Use the same relevant minimal tool allowlist in both primary arms, rather
+than charging one arm the complete unrelated REA catalog. Measure discovery
+separately. Dossier versus primitive versus retained-view organization is a
+secondary question: it must not be confounded with backend quality, task
+selection, tool count or extra information available only to one arm.
+
+Freeze the task set and expected facts before model trials. Run counterbalanced pairs
+serially, retain all planned outcomes, and separate development smoke checks
+from the scored cohort. Report this as a pilot, not a population-level result.
+
+## Resource and data controls
+
+Reuse `../analysis-efficiency/resource-run.py --memory-gib 8 --observe-payload-exit`:
+one CPU, 8 GiB whole-process-tree hard memory, no swap, a 6 GiB early stop,
+192 tasks (browser acquisition may explicitly use the verified 256-task
+ceiling), at least 12 GiB host available memory to start, and a stop below
+4 GiB available. Earlier build/native preflights used the unchanged 4 GiB
+default; the user subsequently authorized 8 GiB total. Run builds,
+acquisition, analysis and model trials one at a time. Retain limit and cleanup
+failures. Payload-exit counters are not final whole-scope counters.
+
+Reuse `agent-trial.py`'s isolated account/configuration, authentication-only
+copy and guaranteed credential removal. Disable shell, browser driving,
+unrelated tools and multi-agent delegation during static trials. Analyze data
+in code without evaluating target JavaScript. Downloads, runtime artifacts,
+original Evidence and transcripts stay outside the checkout. Persist only
+explicit selected settings, never ambient environment or credentials. Guest
+code has a 128 MiB heap, 5 seconds compute per cell excluding backend waits,
+64 KiB source and 512 KiB printed output; both arms share a 64 backend-call
+trial limit including preparation. Model rounds time out after 180 seconds;
+the trial has a 960-second watchdog and at most ten actions.
+
+Preparation uses a fresh production REA process per trial, a 512 MiB parent
+Node old-generation heap and production worker limits. This can truncate the
+semantic graph; retain and report the original coverage. Selected task facts
+must agree with the frozen oracle. Do not generalize this cohort to complete
+semantic reconstruction. Both treatments use identical settings.
+
+Report model input/cached/uncached/output/reasoning usage when observed,
+per-response context observations, discovery and printed intermediate output,
+errors and retries, wall time, CPU and process-family/cgroup memory. Label
+BPE estimates separately from actual model usage and unknown physical counters
+explicitly. Keep startup/preparation versus question-only costs separate;
+do not claim a cache speedup from warmed client schema validation.
+
+## Reuse ledger
+
+- Reuse unchanged: REA production analysis and evidence tools; the artifact
+  corpus identities; owned cgroup resource supervisor; selected Codex rollout
+  capture; isolated profile and authentication cleanup.
+- Adapt: the existing agent runner gains an opt-in executor-host switch; its
+  default remains `inherit` so earlier studies retain their original behavior.
+- Learn: whether this installed Codex/model combination can genuinely expose
+  distinct direct and code execution treatments, and whether benefits survive
+  actual shipped-application tasks.
+- Prototype boundary: no new runtime authority, no IDA database mutation,
+  production integration, global configuration changes or upstream code copied.
+
+## Running the pilot
+
+Use the pinned Node/npm toolchain and an already built runtime. Install
+`quickjs-emscripten@0.31.0` in an isolated temporary prefix; do not add a
+production dependency. Acquire and verify the Obsidian corpus artifact using
+`../analysis-efficiency/corpus.json`. `capture-web.mjs NEW_ABS_DIR ABS_CHROMIUM`
+captures the actual public Excalidraw application in an owned sandboxed
+browser, using the configured HTTPS proxy without logging its credentials.
+
+`prepare.py --data ABS_DATA_ROOT` freezes the eight-trial plan, task bytes and
+oracles after the separate Obsidian selected-source evidence acquisition.
+Its directory names match the recorded experiment acquisition. Each task has
+one direct and one code trial; order alternates between tasks, without a
+second repetition. Run each separately under the resource supervisor:
+
+```sh
+python3 experiments/analysis-efficiency/resource-run.py --memory-gib 8 \
+  --observe-payload-exit -- \
+  python3 experiments/browser-electron-code-mode/trial.py \
+  --arm code --task /tmp/DATA/cohort/TASK.json \
+  --output /tmp/DATA/cohort/TASK-code \
+  --quickjs /tmp/RUNTIME/node_modules/quickjs-emscripten
+```
+
+Retain supervisor output as `/tmp/DATA/cohort/TASK-code.log`.
+`review.py --cohort /tmp/DATA/cohort` checks exact facts and observed resource
+counters. Separately inspect every answer, supporting Evidence and actual
+agent code for claim support, honest limitations and treatment validity.
+The HAR grouping oracle reads original HAR records independently. Obsidian
+counts and module identities are consistency checks against separately
+retained producer Evidence; they do not independently validate the extractor.
+
+The follow-up `prepare_dependencies.py --data ABS_DATA_ROOT` freezes one
+additional Obsidian dependency question. Run both arms with
+`--compositional-followup --max-rounds 32`: direct actions can contain a batch
+of independent calls, and code is explicitly instructed to filter/combine
+before printing. The code arm runs first in this single pair. This is an
+adaptive follow-up prompted by the first cohort's lack of actual composition,
+and is reported separately, with its prompt/protocol changes visible. It does
+not replace the original outcomes. Complete raw replies and task facts remain
+available to both arms; only the model-visible organization differs.
+
+`test_backend.py` uses the real session SDK boundary to verify guest isolation,
+allowlisting, compute/output limits, subsequent-cell recovery and shutdown.
+It requires `REA_EXPERIMENT_QUICKJS` pointing to the isolated QuickJS package
+and should run under the same resource supervisor. It is infrastructure
+verification, not a toy application benchmark. `test_review.py` checks that
+diagnostics cannot attest to Evidence and legitimate answer shapes preserve
+exact facts without repairing incorrect IDs.

+# Browser/Electron code-mode pilot: 2026-10-15
+
+Decision: **inconclusive about the benefit of actual code composition; improve
+the experimental interface before scaling**. This Terra-high pilot did not
+demonstrate reliable composition. Preserve the unsuccessful outcomes.
+
+Ten scored attempts used actual shipped Obsidian 1.14.4 and a frozen startup
+capture from the real public Excalidraw application. The initial four-question
+cohort produced 4/4 successful direct answers and 3/4 successful code answers.
+The code identity answer mistyped one node ID. A separately declared dependent
+module-read follow-up succeeded with batched direct calls and failed in code
+mode. Failed tasks cannot be credited as token savings or faster completion.
+
+## Scope and validity
+
+Production runtime was built from fresh main `6688ed6db`, pinned Node 24.18.0,
+npm 11.16.0. Model configuration was `gpt-5.6-terra`, reasoning `high`, through
+Codex CLI 0.161.0. The requested alias/configuration is observed; a different
+underlying service model identity was not independently verified.
+
+Native direct-MCP versus native code-mode could not be established. Requested
+direct settings still invoked `exec`; disabling the code host rejected that
+operation. An app-server dynamic-tool preflight also failed to dispatch even
+one registered callback with the host disabled. The model said it had called
+the tool; **no actual dynamic callback occurred**. Enabled-host session calls
+worked in the earlier infrastructure smoke. These are excluded preflights.
+
+Scored runs instead use the common external JSON action protocol described in
+README.md. No scored run invoked native tools. Direct actions return complete
+production structured results, with existing summaries/selectors/views allowed.
+Code actions run agent-written JavaScript through the same SDK backend in an
+isolated QuickJS 0.31.0 guest. Both see the same relevant two-tool menu and
+original contracts on demand. Original complete SDK replies remain retained.
+
+Each action uses a fresh CLI invocation and replays the history. Thus round
+count also changes repeated client instructions, schema exposure and startup
+cost. This is a controlled protocol pilot, not native production latency.
+
+Artifact bytes, task files and expected facts were frozen before the scored
+samples. The first cohort alternates arm order by question, one repetition.
+The adaptive follow-up enables direct batches and explicitly instructs code-side
+projection, with code first in one pair. It is a distinct condition, not a
+replacement for the first cohort or a statistically controlled replication.
+
+Both backends use the same 512 MiB parent heap policy and production worker
+limits. Semantic graphs can be truncated; dynamic available-heap metadata and
+parent Evidence identities differ. Selected task facts agree with separate
+producer oracles, but byte-identical complete-information parity is unverified.
+This study cannot establish a causal advantage of information organization.
+
+## Inputs and correctness
+
+- Official Obsidian ASAR: 27,477,966 bytes, SHA-256
+  `146ef8470d8cbb4a6db209bdc19bf2bad13350444186c0fd93c31087b142b92f`.
+  Published artifact: [official ASAR gzip](https://github.com/obsidianmd/obsidian-releases/releases/download/v1.14.4/obsidian-1.14.4.asar.gz).
+  Static selected-source analysis: package.json and main.js; 36 inventoried

+- Actual Excalidraw startup: 39 recorded requests, 4,437,000-byte HAR, SHA-256
+  `680483155d4e0d4a67aca437de5309e741580f4710c170de508b8d0bd9fdb9e9`.
+  Owned empty-profile Chromium 156.0.8078.4, sandbox/TLS checks enabled, configured
+  HTTPS proxy, browser closed. One producer status is -1; both successful
+  answers explicitly say it does not establish an HTTP response. This is one
+  startup window, not complete application behavior.
+
+The HAR grouping oracle independently reads original HAR records. Obsidian
+counts/module identities/specifiers are consistency checks against separate
+production Evidence, not an independent proof of extractor correctness.
+All final answers and supporting successful Evidence envelopes were inspected.
+Diagnostics and target strings cannot attest to an Evidence ID.
+
+Grading accepts factual equivalents the questions did not forbid: node IDs
+as a flat list or kind-grouped lists, sender observations as an integer or
+count object, and limitations as prose or strings. These shape corrections
+were made after seeing legitimate answers; no model answer, expected ID or
+expected count was repaired. The code identity typo remains a failure.
+
+## Actual model usage and latency
+
+Input includes cached tokens. Uncached = input minus cached. Output includes
+reasoning; reasoning is not added twice. These are observed client/model counts,
+not BPE estimates or dollar-cost estimates. Max input is the largest observed
+single request, not an exact dump of model context. All completed-turn usage
+was available for all ten attempts.
+
+Question seconds exclude the common initial SDK/analysis preparation. Whole
+scope wall and CPU below include that preparation and shutdown. Remote model
+service CPU/GPU usage and itemized schema-token ablation were not measured.

+## Local resources and discovery
+
+All trials ran serially with one CPU, an 8 GiB whole-scope hard cap, 6 GiB
+early stop, no swap, 192 tasks, at least 12 GiB host available memory at start,
+and a 4 GiB host reserve. Every scored payload-exit receipt verified cleanup
+and zero OOM/limit events. Transient whole-scope final counters disappeared;
+**they remain unknown**, rather than being substituted with payload counters.
+Kernel cgroup memory includes process-family memory and charged cache, not
+summed process RSS. The maximum scored peak was 1,210,003,456 bytes (1.13 GiB).
+Initial build/native preflights used the earlier 4 GiB default.
+
+These are fresh backend/model sessions with an already built runtime and warm
+host filesystem caches. No intentional cold-cache flush or repeated warm
+analysis measurement was performed. Observed model cache hits are shown above;
+they do not establish an analysis-cache speedup.

+
+Discovery KiB counts returned original contracts, already included in observation
+KiB. Discovery and subsequent history/schema replay are included in model usage;
+their isolated causal token cost was not measured. CPU for question-only work
+was not separately instrumented. Preparation had a substantial outlier and is
+reported separately rather than attributed to code organization.
+
+## What the traces show
+
+- Initial code cells were RPC wrappers printing complete results; none performed
+  a meaningful programmatic join, filtering or aggregation. Their lower round
+  counts are not evidence for a code-composition mechanism.
+- Excalidraw code used 59,768 input tokens versus direct 74,055, but code uncached
+  input was 59,768 versus direct 58,183. Code question time was 60.55 s versus
+  56.84 s. Fewer total input tokens did not imply less uncached work or faster
+  completion in this pair.
+- Both modes repeatedly investigated facts already present in the summary and
+  encountered ambiguous `main.js` item selectors. Discovery, provenance metadata,
+  extra calls and retries matter even when the relevant menu contains two tools.
+- Code's identity answer substituted one long ID. Access to JavaScript did not
+  prevent the final model response from corrupting an identifier.
+- The dependency follow-up asks for external literal specifiers and occurrence
+  counts across all 23 main.js module identities, excluding duplicate unresolved
+  references. Direct used actual batches, retrieved item facts and correctly
+  returned ten external modules, without claiming runtime loading. Code copied
+  an invalid ID, did not compose its reads, and returned an unfinished progress
+  string. Its smaller token/time totals are **failed-task costs**, not savings.
+- Both modes correctly refused to equate one static sender-check observation
+  with authorization enforcement for every IPC handler. Neither claimed a
+  vulnerability from missing coverage.
+
+## Decision and next experimental change
+
+Do not scale this wrapper protocol or treat these results as a reason to replace
+REA's current interface. The useful signal is that a code tool's availability
+alone did not produce effective composition, while metadata/discovery and exact
+identity preservation are measurable burdens. The hypothesis about competent
+code composition remains untested here.
+
+The next bounded study should establish a natural tool-feedback loop that can
+actually expose distinct treatments; freeze equivalent retained Evidence; permit
+baseline batching; test generic typed/discoverable code primitives on a real
+application question; and verify actual agent-written composition before scaling.
+Retained materialized answers that avoid identifier retyping are another factor
+worth testing separately. Dossier versus primitives versus retained views was
+not compared in this pilot. No cache or analysis-speed optimization is claimed.
+
+## Reproduction and evidence
+
+Executed validation: pinned runtime build; 63 existing analysis-efficiency
+Python tests; four grader boundary tests; two real SDK/sandbox lifecycle tests;
+Python compilation and JavaScript syntax checks; affected-file formatting;
+`npm run check:fast` (typecheck and lint). The final fast check completed in
+56.23 seconds with a verified kernel peak of 4,545,388,544 bytes (4.23 GiB),
+zero observed OOM/limit events and verified payload cleanup. The 8/6 GiB
+memory limits, zero swap, one-CPU quota/affinity and task ceiling were also
+read from the actual owned kernel cgroup and asserted before that check.
+
+Local evidence root: `/tmp/rea-codemode-experiment-20261015`. It contains pinned
+acquisition receipts, full original SDK responses, prompts/actions/observations,
+selected Codex tool/usage traces, answers, frozen plans/oracles and resource
+receipts. `cohort/review.json` and `dependencies/review.json` are machine-readable.
+Raw artifacts, credentials, runtime packages and temporary plans are not committed.
+Temporary auth/account profiles were deleted after every trial and preflight.
+
+Executed v1/v2 sources are retained in `sources-v1/` and `sources-v2/`. V1 source
+hashes were measured at receipt time; a measurement-only usage-field patch landed
+during the first trial, so those digests do not attest to exact loaded driver
+bytes. V2 hashes were captured at startup. Subsequent changes only strengthen
+argument validation and teardown failure paths; no scored answer was rerun or
+repaired. The production runtime stayed pinned throughout.

+# Code-friendly JavaScript investigation data: design prototype
+
+Status: experimental query/client implemented on this branch; not integrated upstream.
+Tracking: [experiment #4063](https://github.com/morluto/rea/issues/4063).
+Executed findings: [results and limitations](results-2026-10-15.md).
+The original design sketch below predates the implementation; its future names
+are illustrative. The implemented surface is described first.
+
+The first typed-interface pilot is preserved under `results/2026-10-15-typed-pilot`:
+direct passed 2/2, code 1/2. Code confused raw Evidence replies with SDK `Result`,
+then manually reported 11 external modules for a correct ten-entry dictionary.
+JavaScript-only narrow discovery also imposed avoidable work on the HAR task.
+These outcomes are retained, not repaired or replaced.
+
+An adaptive `--interface typed-result` profile makes generic code calls and SDK
+methods consistently return `Result`, handles transport failures explicitly,
+and keeps complete discovery for capture tasks. `freeze-snapshot.py` creates a
+temporary authenticated bundle and an additional plan; both arms import those
+exact bytes instead of reanalyzing under dynamic parent result budgets. Run its
+trials with `--interface typed-result --compositional-followup --max-rounds 16`.
+This combines an interface correction and a stricter input control, so comparing
+the two cohorts cannot isolate either change's effect. Original `current` and
+`typed` profiles remain available to reproduce the earlier interfaces.
+Source inspection: fresh main `d7651b6a0`, 2026-10-15. This follows the
+`experiment/browser-electron-codemode-20261015` pilot, commit `6494c98c6`.
+
+The design question is whether REA's investigation data and contracts can make
+ordinary agent-written JavaScript useful. Adding an executor around existing
+MCP calls does not resolve untyped results, repetitive envelopes, missing list
+fields, ambiguous paths, or identity transcription.
+
+## Implemented prototype
+
+The canonical `inspect_analysis_view` contract now accepts:
+
+```json
+{
+  "source": { "kind": "retained-evidence", "evidence_id": "<parent>" },
+  "view": {
+    "kind": "javascript",
+    "collection": "modules",
+    "projection": "references",
+    "where": { "path": "main.js", "kind": "javascript-module" },
+    "offset": 0,
+    "limit": 64
+  }
+}
+```
+
+The typed `rows` contain canonical node identity, exact/unknown path, retained
+source-range count and unique observation authority/state/confidence triples.
+`source_coverage` preserves selection, application/semantic bounds and unknown
+counts independently of filtered-page coverage. Omitted filters select all;
+`path: null` selects unknown paths and `path: ""` selects empty references.
+Paths can match several identities. Original module items remain accessible.
+The owner scans the immutable graph once and allocates only the requested rows;
+it does not allocate a full matching inventory or source-range arrays.
+
+The experimental [client](client.mjs) borrows canonical TypeScript types;
+[discovery](discovery.mjs) generates narrow JSON Schemas from named canonical
+schemas, with complete original discovery still available. Both direct and
+code treatments receive the same discovery and backend. The client uses normal
+`await` and `for await`; failures are explicit `Result` values. Its page iterator
+binds parent and filters; offsets refer to that immutable query. This prototype
+uses existing offsets, not the originally proposed opaque cursors. No query
+cache, report-retention API, IPC/network redesign or production executor was
+added. General agent code is confined to the opt-in experimental host.
+
+```js
+const app = rea.javascript.fromEvidence(parentEvidenceId);
+const counts = {};
+const evidenceIds = [];
+for await (const result of app.modules.pages({
+  where: { path: "main.js", kind: "javascript-module" },
+})) {
+  if (!result.ok) throw new Error(JSON.stringify(result.error));
+  evidenceIds.push(result.value.evidence_id);
+  for (const row of result.value.page.rows) {
+    const id = row.identity;
+    if (id.strategy === "artifact-local-key" &&
+        id.namespace === "unresolved-semantic-module" &&
+        id.key.startsWith("external:")) {
+      const name = id.key.slice(9);
+      counts[name] = (counts[name] ?? 0) + row.retained_source_range_count;
+    }
+  }
+}
+print({ counts, evidenceIds }); // derived output; not minted source Evidence
+```
+
+`verify.py` compares this actual public MCP query against all selected original
+items from the real Obsidian ASAR, then checks four SDK pages, early exit and
+missing-parent errors. The executed run matched all 23 module identities and
+ten external specifiers/counts, retaining 36 unselected files. Full structured
+replies were 338,208 bytes for the legacy page/items and 23,402 for the new query.
+First retained-query round trip was 0.101 s; repeated reads were 0.012/0.015 s.
+Whole verification used 21.167 s wall, 20.906 s CPU and 1,167,003,648 bytes peak
+at verified payload exit. These are boundary/projection measurements, not agent
+performance or a new cache speedup.
+
+## Reproducing and retaining experiments
+
+Use pinned Node/npm and `npm ci && npm run build:cached`. Install
+`quickjs-emscripten@0.31.0` in an isolated temporary prefix, not production deps.
+Run heavy commands serially under `../analysis-efficiency/resource-run.py
+--memory-gib 8 --observe-payload-exit -- COMMAND...`: one CPU, 8 GiB whole
+process-family cap, 6 GiB early stop and no swap. Browser acquisition requires
+its explicitly selected executable and the existing 256-task ceiling.
+
+Download the official [Obsidian 1.14.4 ASAR gzip](https://github.com/obsidianmd/obsidian-releases/releases/download/v1.14.4/obsidian-1.14.4.asar.gz)
+and decompress to `DATA/artifacts/obsidian-1.14.4.asar`. Gzip SHA-256 is

+`146ef8470d8cbb4a6db209bdc19bf2bad13350444186c0fd93c31087b142b92f`.
+No target code is executed by the static acquisition or analysis.
+
+1. `acquire-oracle.py --data DATA` regenerates selected-source producer facts.
+2. `../browser-electron-code-mode/capture-web.mjs DATA/excalidraw-proxy ABS_CHROMIUM`
+   (run with Node) records the real Excalidraw startup in an owned empty-profile,
+   TLS-verified, sandboxed browser. It contacts the public site. A new capture
+   has a new digest/oracle; the historical live-web bytes are not reproducible.
+3. Run the original `prepare.py --data DATA` and `prepare_dependencies.py --data
+   DATA` in `../browser-electron-code-mode/` to regenerate plans/oracles.
+4. This directory's `prepare.py --data DATA --output COHORT` freezes the new
+   typed-interface tasks, oracle, counterbalanced order and source fingerprints.
+5. For every plan entry run the existing `trial.py` under the supervisor with
+   `--interface typed --compositional-followup --max-rounds 16`, the declared
+   `--arm`, `--task`, fresh `--output COHORT/TASK-ARM`, and absolute `--quickjs`.
+   Save supervisor output to `COHORT/TASK-ARM.log`.
+6. Run the original `review.py --cohort COHORT`; manually check support,
+   limitations and whether code actually composed/filter/grouped facts.
+7. `retain.py --cohort COHORT --output SAVED` saves task/oracle, actual model
+   actions and CLI events/usage, answers, failures, Evidence-response digests
+   and resource receipts, with a byte checksum manifest. It never recursively
+   copies profiles, auth, configuration, applications, HARs or full producer
+   payloads. `review.py` can regrade saved records using the Evidence index.
+
+Recorded snapshots under [results/](results/) are excluded from reformatting
+because task hashes and recorded-byte manifests must remain stable. Downloadable
+applications and regenerable bulky Evidence are intentionally not archived.
+The retained model sampling/results are valuable non-regenerable observations;
+identical future model outputs or original live-web captures are not promised.
+Keep original failures. Historical pilot results are a separate cohort, not a
+third randomized arm of the new comparison. A fresh model process with full
+history per action remains an external controlled protocol; this is not a
+native Codex tool-host latency benchmark.
+
+Generate/check the client's declarations without a second hand-maintained schema:
+
+```sh
+node_modules/.bin/tsc --ignoreConfig --allowJs --checkJs --declaration \
+  --emitDeclarationOnly --outDir .cache/codemode-sdk --target ES2023 \
+  --lib ES2023 --types node --module NodeNext --moduleResolution NodeNext \
+  --strict --skipLibCheck experiments/codemode-data-contract/client.mjs

+| A path can identify an asset and several logical modules           | `main.js` is ambiguous; a caller must preserve node identities   | Snapshot-bound canonical references passed as code values                                  |
+| Each item repeats a complete Evidence envelope                     | Repeated metadata enters context when copied verbatim            | A query Evidence envelope with rows and shared provenance/coverage                         |
+
+Source boundaries:
+[module projection](../../src/domain/analysisView/javascriptApplicationView.ts),
+[generic view schemas](../../src/domain/analysisView/analysisView.ts),
+[authenticated retained reads](../../src/application/analysisView/AnalysisViewService.ts),
+[current tool contract](../../src/contracts/analysisViewToolContracts.ts).
+The existing retention/authentication boundary is useful and should be reused.
+
+## Boundary: shared data primitives, with a generated code interface
+
+1. **Shared application/domain queries.** Read immutable retained Evidence and
+   return typed module, IPC or network records. Own selectors, projection,
+   ordering, coverage and provenance here. Use the existing parsed facts; do
+   not introduce another JavaScript/Electron parser in a code-mode adapter.
+2. **CLI/MCP adapters and a generated JavaScript/TypeScript SDK.** Both consume
+   those same queries. Code methods expose familiar objects and `async/await`,
+   precise inputs/results, and ordinary arrays/iterators. Canonical contracts
+   remain the source of truth; avoid a separately maintained SDK semantics.
+3. **The agent's existing code host.** Run loops, joins and task-specific
+   calculations there, returning only useful results. The initial design does
+   not require REA to add a general-purpose server-side execution tool or VM.
+
+Self-owned Electron/browser analysis is a good starting point because REA can
+change both the result representation and its query boundary. An external
+engine can later supply records through an adapter without dictating this API.
+
+The closest alternative is a thin SDK that forwards the current MCP contract.
+It improves syntax but retains the current output/discovery problems. A
+task-specific dossier is also useful for recurring questions, but is a separate
+organization factor; it should not replace reusable facts needed by scripts.
+
+## First candidate contract
+
+Extend retained JavaScript views with a named typed module projection. This
+shares the intent and authority of `inspect_analysis_view`; start there rather
+than adding a public tool for every SDK method. For example, a new JavaScript
+view variant could describe this request:
+
+```ts
+type ModuleReferencesRequest = {
+  source: { kind: "retained-evidence"; evidence_id: EvidenceId };
+  view: {
+    kind: "javascript";
+    collection: "modules";
+    projection: "references";
+    where: { path?: string; kind?: ModuleKind };
+    cursor?: string;
+    limit?: number;
+  };
+};
+
+type ModuleReferenceRow = {
+  node_id: ApplicationNodeId;
+  path: string | null;
+  kind: ModuleKind;
+  identity: ApplicationNodeIdentity;
+  retained_source_range_count: number;
+  basis: ModuleReferenceBasis;
+};
+
+type ModuleReferencePage = {
+  rows: readonly ModuleReferenceRow[];
+  source: QuerySourceReference;
+  coverage: QueryCoverage;
+  limitations: readonly string[];
+};
+```
+
+These are proposed names and shapes, not current exports. Production schemas
+must use the existing identity and tagged error types, exact named contracts,
+and validate converted advertised JSON Schemas against the actual clients.
+
+The projection returns the owner's retained range count, not a claim about
+unique runtime calls. More detailed locations/observations remain accessible
+through exact module reads. Later projections may cover IPC endpoints and
+network transactions; their ownership and unknown semantics must first be
+defined from existing producing boundaries.
+
+Prefer named domain projections and a small set of typed filters. An arbitrary
+JSONPath/SQL language is unnecessary for this first question. JavaScript can do
+the task-specific grouping. Push basic selection/projection into the query
+owner so neither the model nor its code host must fetch irrelevant full data.
+
+The SDK can generate `app.modules.pages(...)` from this canonical variant,
+without publishing a second runtime alias or making catalog ordering select
+an operation. Full discovery stays available; the model can read one namespace
+and method's actual types/documentation as needed.
+
+## What agent code should look like
+
+Illustrative future API, not a runnable claim:
+
+```ts
+const app = rea.javascript.fromEvidence(parentEvidenceId);
+const counts = new Map<string, number>();
+const sources = [];
+
+for await (const result of app.modules.pages({
+  where: { path: "main.js", kind: "javascript-module" },
+  projection: "references",
+})) {
+  if (!result.ok) return result;
+  sources.push(result.value.source);
+  for (const row of result.value.rows) {
+    const id = row.identity;
+    if (id.strategy !== "artifact-local-key") continue;
+    if (id.namespace === "unresolved-semantic-module" &&
+        id.key.startsWith("external:")) {
+      const name = id.key.slice("external:".length);
+      counts.set(name, (counts.get(name) ?? 0) + row.retained_source_range_count);
+    }
+  }
+}
+
+return rea.report(Object.fromEntries(counts), { sources });
+```
+
+The agent chooses the loop, predicate and interpretation. This is a reusable
+module-reference API, not an Obsidian-specific dependency tool. Module refs
+remain canonical values in program memory; subsequent reads bind the parent
+Evidence ID and node ID together rather than asking the model to retype hashes.
+A snapshot-bound SDK object is convenience, not proof of authority: the server
+still authenticates every reference at the existing Evidence boundary.
+
+The production identity union needs proper narrowing; generated types must
+describe when namespace/key are available, rather than pretending every module
+has them. Unavailable fields remain explicit unknowns. The illustrated
+`rea.report` would retain code-derived output with source/query references,
+coverage and script digest, while labelling it as a derivation. Merely running
+code does not establish the truth of an arbitrary conclusion or runtime
+authorization. Do not mint source-observation Evidence for an agent claim.
+The SDK obtains the query reference from the outer canonical Evidence envelope;
+the hashed normalized result must not embed its own Evidence ID. Reporting
+resolves those references at the existing ownership boundary rather than
+trusting client-supplied coverage assertions.
+
+## Ownership, paging and resource semantics
+
+- Bind every read and cursor to immutable parent Evidence, normalized selector,
+  projection/version and stable ordering. A cursor for another snapshot/query
+  fails explicitly. Exhausting retained rows does not establish complete source
+  or runtime coverage. A stopped iterator retains partial consumption.
+- Homogeneous exact-item batches preserve caller order, duplicates, per-item
+  failures and support references. They are available to direct callers too.
+- Share provenance once per query/page while retaining source references for
+  rows and explicit row confidence/authority with supporting observation states.
+  Mixed or unknown support must not become an observed fact. Keep complete
+  Evidence accessible. Caller-requested complete detail is
+  not silently replaced with a compact projection.
+- Build reusable indexes only over verified immutable facts. A query cache key
+  includes parent Evidence ID, selector/projection, ordering and contract
+  version; its lifetime belongs to the owning session/snapshot. Artifact
+  analysis caching additionally needs bytes, selections, parser/options and
+  version. No cache speedup is measured by this probe.
+- Live browser/Electron state must first have explicit snapshot identity and
+  freshness semantics. Reading a retained capture does not silently refresh,
+  navigate, attach, execute target code or acquire more authority.
+- Bound pages/serialization before allocation using real transport/resource
+  limits, with cancellation and cleanup. SDK iterators release resources on
+  early exit; reports deduplicate supporting references and retain metadata,
+  not copies of every input row. Concurrency remains bounded.
+
+## Recorded real-artifact probe
+
+`module-reference-probe.mjs` consumes the pilot's real Obsidian owner-produced
+module pages/items, not a demo application or a new parser. It proves that a
+compact reference-row representation can retain the requested facts:
+
+- 23 canonical `main.js` JavaScript-module identities;
+- all ten external specifiers with exact retained source-range counts;
+- parent/root artifact identity and supporting view IDs;
+- partial application/semantic coverage and 36 unselected files;
+- an explicit failure when a required item fact is missing;
+- caller edits to a result cannot modify the retained snapshot's facts.
+
+On those recorded inputs, current structured page plus 23 item envelopes were
+325,215 UTF-8 bytes. The first projection was 15,471 bytes; retaining explicit
+per-row confidence/authority and supporting observation states increased the
+final projection to 17,989 bytes. This metadata is necessary, not discarded to
+improve the byte count. The final probe, including detached result ownership,
+used about 0.56 ms for its first projection. Whole-scope wall time was 0.322 s,
+CPU at payload exit 0.096 s, and verified kernel cgroup peak 20,697,088 bytes.
+It ran under the existing supervisor: one CPU, 8 GiB cap, 6 GiB early stop,
+no swap; no OOM. These are local projection measurements, not analysis timing.
+
+This is a serialization/contract probe. It does not measure agent tokens,
+completed-task latency, live-provider behavior, or a new integrated query. It
+does not replace production Evidence authentication/retention. The compact
+representation benefits direct calls as well as code mode; bytes alone do not
+establish a code-mode advantage.
+
+Run with pinned Node and the existing resource supervisor:
+
+```sh
+node experiments/codemode-data-contract/module-reference-probe.mjs \
+  /tmp/rea-codemode-experiment-20261015/obsidian-oracle
+```
+
+## Verification before integration and the next agent comparison
+
+Implement the typed producer projection and shared application query first.
+Verify actual CLI/MCP parity, exact references, ambiguous paths, duplicate batch
+selectors, unknown fields, partial/truncated sources, cursor mismatch, changed
+artifacts, cancellation, resource admission and SDK-converted schemas. Reuse
+the original Obsidian artifact and Excalidraw capture, then add genuine tasks
+requiring IPC/source or transaction joins; do not add target execution implicitly.
+
+Compare separately:
+
+| Condition                  | Data/query backend                | Interaction                                       |
+| -------------------------- | --------------------------------- | ------------------------------------------------- |
+| Existing direct workflow   | Existing views                    | Current direct tools                              |
+| Redesigned direct workflow | New typed projection/query        | Direct calls, with batching                       |
+| Redesigned code workflow   | Identical new query and snapshots | Generated SDK and actual model-written JavaScript |
+
+The first comparison measures the data-interface change; the second measures
+code composition with equivalent available facts. Preserve discovery/schema
+costs, final identity transcription, errors and failed attempts. Verify actual
+composition and a natural tool-feedback loop before scaling Terra-high runs.
+Measure completed tasks, actual input/cached/output tokens, largest requests,
+wall/CPU and process-family peak memory. Separate analysis preparation, cold and
+warm runs and source completeness. Dossier and retained-answer variants should
+be isolated follow-ups. Continue to accept null and negative outcomes.
+
+Prior art: [Cloudflare Code Mode](https://blog.cloudflare.com/code-mode/) describes
+typed APIs and multi-call composition; [Anthropic's MCP execution article](https://www.anthropic.com/engineering/code-execution-with-mcp)
+describes on-demand discovery and filtering before model context. Their reported
+benefits do not establish REA performance.

+# Code-friendly tool design: exploratory results
+
+Tracking: [#4063](https://github.com/morluto/rea/issues/4063).
+The typed data interface worked on a real shipped Electron application. Merely
+wrapping tools in code did not reliably produce composition. An adaptive
+interface correction finally produced a genuine SDK aggregation on identical
+retained input. This is a useful feasibility signal, not an efficiency claim.
+
+## What was implemented
+
+- A canonical typed module-reference view shared by CLI and MCP, with exact
+  filters, canonical identities, retained range counts, observation support,
+  independent source coverage and original Evidence links. Original item reads
+  remain available. No second JavaScript parser was added.
+- An experimental typed client and narrow discovery generated from named
+  canonical schemas. Normal async/await and iterators work in the isolated
+  experimental host. Production REA gains no arbitrary execution tool.
+- Reproducible preparation, grading and retention scripts, plus authenticated
+  public bundle import/export for an exact-snapshot follow-up. Applications,
+  captures, generated full Evidence and the temporary bundle are not archived.
+
+Sources sampled at `2c2c8df8d` (typed pilot) and `dec85f4cf` (adaptive follow-up).
+Driver fingerprints and original executed-source snapshots are retained.
+
+## Real applications and verification
+
+The Electron question reviews external references in the actual published
+Obsidian 1.14.4 `main.js`, selected with `package.json` from its ASAR. The browser
+question groups all 39 requests in an owned empty-profile startup capture of
+the actual public Excalidraw application. These are public application tasks,
+not CTFs, synthetic applications or demonstration benchmarks.
+
+The Obsidian oracle checks consistency against separately retained producer
+items, not independent semantic extractor correctness. HAR grouping is decoded
+independently from the original capture. One recorded status `-1` is an
+unfinished capture entry, not an HTTP status or a proved server failure.
+
+The executed real MCP verification matched all 23 selected module identities,
+the ten external specifiers and every retained range count against original
+item facts. Partial coverage and 36 unselected files remained explicit. Four
+SDK pages, early iterator exit and missing-parent failure also passed.
+Legacy page plus item replies were 338,208 structured bytes; the new reference
+query was 23,402 bytes. This establishes representation and call-count changes,
+not agent token savings. First retained-query round trip was 101 ms; two repeated
+reads were 12/15 ms. No new query cache was introduced, and these are not cold
+artifact-analysis timings.
+
+See [executed boundary metrics](results/verification/real-obsidian-query.json).
+
+## First typed-interface cohort
+
+One counterbalanced pair per task; direct batches were permitted. Both arms
+used the same runtime, artifact/capture inputs and available tools. Fresh
+Obsidian analyses produced different parent IDs because dynamic parent result
+budgets differed; selected question facts agreed. This cohort therefore does
+not establish full-snapshot equivalence.
+
+| Task                | Arm    | Correct |   Input | Cached input | Output | Largest request input | Answer seconds |

+| Obsidian references | Code   | No      |  53,972 |        7,936 |  1,585 |                23,673 |         83.381 |
+| Obsidian references | Direct | Yes     |  52,974 |        7,936 |    675 |                22,929 |         48.759 |
+| Excalidraw grouping | Direct | Yes     | 111,383 |        7,936 |  1,832 |                33,994 |        104.278 |
+| Excalidraw grouping | Code   | Yes     | 119,147 |       15,872 |  2,087 |                27,830 |        115.196 |
+
+Input includes cached input. Output includes reported reasoning. These are
+actual CLI usage counters, not byte/BPE estimates. Largest request input is an
+observed context proxy, not a measurement of the model's internal context.
+Answer time excludes preparation and includes discovery, code/errors and final
+answer generation. Every model action launches a fresh CLI and replays history.

+
+Observed failures matter:
+
+- Obsidian code expected `Result` from a raw Evidence-returning call and threw
+  the successful reply as an error. It then manually returned eleven external
+  modules alongside a correct ten-entry dictionary. This fails correctness.
+- Excalidraw code only printed replies; it did not programmatically group
+  records. JavaScript-only narrow discovery and invalid selectors caused extra
+  work. Passing facts therefore do not establish successful code composition.
+- Direct completed both tasks. This small cohort does not support a code-mode
+  advantage. Its failed code task earns no efficiency credit.
+
+Full records: [typed pilot](results/2026-10-15-typed-pilot/).
+
+## Adaptive exact-snapshot pair
+
+The next opt-in profile makes generic code calls and SDK methods consistently
+return `Result`; it also keeps complete discovery for capture tasks. Both arms
+imported the same authenticated 1,076,410-byte temporary bundle, SHA-256
+`130b59412d2aa4613cf6b095039642e4e397969f6ab764e699bbe985a2673b6d`.
+Snapshot preparation cost 64.512 s (scope wall 64.914 s), 49.049 family CPU seconds
+and 1,079,283,712 peak bytes, once before the comparison.
+
+Both arms produced byte-equivalent structured query Evidence:
+`ev_faea596d8c9779fd463185bad16bcba6faa1acda9bb77df2446c109a9c4c9204`.
+The parent, filtered rows, query parameters, provenance and coverage matched,
+not just the requested scalar answers. See the [parity assertions](results/verification/shared-snapshot-parity.json).
+
+| Arm    | Correct | Input / uncached | Output | Largest request input | Answer seconds | Preparation seconds | Family CPU seconds |    Peak bytes |
+| ------ | ------- | ---------------: | -----: | --------------------: | -------------: | ------------------: | -----------------: | ------------: |
+| Direct | No      |  50,946 / 50,946 |    621 |                22,205 |         63.888 |              11.739 |             16.797 | 1,085,665,280 |
+| Code   | Yes     |  45,898 / 45,898 |  1,224 |                16,831 |         43.770 |              11.077 |             15.920 | 1,082,523,648 |
+
+Each used three model rounds, one discovery action and two backend calls
+(import plus query). The code used `rea.javascript.fromEvidence(...).modules.references`,
+filtered the identity union, summed retained ranges and computed
+`Object.keys(...).length`. Its cell completed and printed selected derived
+facts with actual supporting IDs. This was genuine computation over records.
+Direct returned the same ten-entry dictionary but claimed eleven external
+modules; that answer fails. Neither answer claimed runtime loading.
+
+No completed-task speedup can be inferred from a failed baseline. This is one
+adaptive pair with different individual model samples, not repeated evidence
+of superiority. The snapshot and interface changes are combined, so differences
+between cohorts cannot isolate either cause. Post-correction network-agent
+behavior has not been measured. No more samples were added to chase a win.
+
+Full records: [shared-snapshot pair](results/2026-10-15-shared-snapshot/).
+A missing reporting-only `oracle_scope` field was repaired after sampling;
+task/oracle bytes, snapshot, model protocol and executed drivers were unchanged.
+
+## Costs, retention and limits
+
+All trials used local Codex CLI 0.161.0, configured `gpt-5.6-terra`, high reasoning,
+and the controlled external JSON action protocol. Scored trials had zero native
+tool calls. This measures that protocol, not native Codex MCP versus native
+code-host latency. Replayed instructions, schemas, intermediate values, errors
+and final output all contribute to recorded input/output usage. Model/provider
+latency and cache variation are not controlled by the local CPU limit.
+
+An earlier operator-aborted attempt overlapped a pre-push check. It is preserved
+[separately](results/2026-10-15-typed-interrupted/): at least 13,646 input (7,936
+cached) and 53 output tokens, 57.311 s trial wall and 22.900 family CPU seconds.
+Usage from the cancelled in-flight turn is unobserved; total cost is incomplete.
+It is not silently dropped or counted as a successful task.
+
+Heavy jobs ran serially apart from that disclosed overlap. The supervisor used
+one CPU affinity, 8 GiB cap, 6 GiB early stop, no swap and a host-memory reserve.
+All recorded scopes reported no OOM and verified payload cleanup. CPU and peaks
+above are kernel cgroup observations at verified payload exit, including small
+observer overhead; vanished final whole-scope counters remain unknown. The
+largest recorded local static/pre-push check peak was 6,304,075,776 bytes (about 5.87 GiB), below the 6 GiB early stop.
+
+The original eight-trial pilot and two-trial dependency follow-up are retained
+as separate historical cohorts, not a randomized third arm. Their runtime,
+discovery and wording differ; no causal token ratio against them is claimed.
+Executed-source snapshots preserve the earlier measurement-only driver change.
+
+Saved records contain tasks/oracles, actual model actions and CLI events/usage,
+answers, failure diagnostics, response digests, source fingerprints and resource
+receipts. They contain no downloaded applications, raw HARs, full regenerable
+producer payloads, profiles or credentials. Some diagnostic prefixes explicitly
+omit dumped full Evidence while retaining its byte digest. Archive manifests
+remain byte-stable. A rerun creates new snapshots/captures and new digests; the
+original transient parent cannot be reconstructed byte-for-byte from a live
+site or dynamic budget alone.
+
+## What this supports next
+
+Keep the shared typed data boundary and consistent code-result convention as
+candidates. Measure repeated, preregistered completed tasks before choosing a
+default interface. Include a controlled legacy-direct arm on the same snapshot
+to isolate data-interface gains, then separate SDK/discovery choices. Additional
+IPC/source joins and richer browser workflows remain unmeasured. Dossier and
+retained-report organizations should be separate factors with the same facts.
+
+Executed validation: 135 focused source/service, CLI/MCP, bridge and schema-profile
+tests; SDK declaration generation/typechecking; build, static checks and generated
+documentation checks. These do not establish live Electron runtime, debugger,
+protection recovery, or large-capacity performance. No production integration
+or broad code-mode efficiency conclusion is proposed by this experiment.

Return external_specifiers as an object mapping each literal external module specifier to its number of retained source_ranges, selecting only identity.namespace unresolved-semantic-module with identity.key starting external:. Strip only that prefix. Do not count unresolved-reference identities a second time. Return module_identity_count (all javascript-module identities for main.js), external_module_count, inventory_exhausted, runtime_load_proven (boolean), artifact_sha256 (the original ASAR digest), evidence_ids (sufficient actual supporting REA Evidence IDs), and concise limitations. Do not execute target code, fetch URLs, infer installed versions or claim runtime loading from static references. The initial selected-source summary and retained parent are supplied. Use the smallest sufficient observations and finish once all requested facts are supported."
