+# Kuna provider
+
+[Kuna](https://github.com/Noelo-Lab/kuna) is an Apache-2.0 decompiler distributed as one `kuna` executable. REA uses a `kuna` you supply. It does not download, install, update or bundle Kuna. REA verified this provider with Kuna 1.833; it accepts other releases and reports them as unverified in `rea doctor` and in each analysis profile.
+
+Kuna is static: it reads the selected image and never executes it.

+## Configure

+export REA_KUNA_COMMAND=/absolute/path/to/kuna
+rea doctor --provider kuna
+```
+
+Select it explicitly with `--provider kuna`, MCP's `open_binary.provider_id: "kuna"`, or `REA_ANALYSIS_PROVIDER=kuna`. With Kuna and another provider configured for the same target, `auto` reports `ambiguous` instead of choosing one.

+
+## How answers are produced
+
+The first analysis request in a session looks for this target's export in the cache. `list_documents` reads the selected path without initializing analysis. The export is keyed by the target's SHA-256, the Kuna executable's SHA-256, its version and `--jobs`.
+
+- **Warm cache:** analysis reads reuse the verified export. A fresh server verifies its file digests; that cost scales with export size.
+- **Cold cache:**
+  - REA starts `kuna decompile-project` in the background on a private copy of the target.
+  - Meanwhile, pseudocode comes from one `kuna decompile --addr` run, and listings from `kuna functions --json`.
+  - Requests for the same function share one run; it stops when its last waiting request is cancelled. Each run analyzes the whole image again in its own process, so one REA process runs at most as many at once as the host has cores beyond `REA_KUNA_JOBS` (at least one). Further requests wait in order, and a waiting request is answered from the export if it finishes first.
+  - Assembly and data names wait for the export; progress notifications report the wait every ten seconds.
+  - A single-function answer says so in its limitations. It lacks the export's whole-program prototypes, so a later request can return different text for the same function.
+
+Pseudocode, assembly, `analyze_function` and data-name answers record where their text came from in `raw_result.source`: `single-function`, or `project-export` with the cache directory. `procedure_pseudo_code` and `procedure_assembly` answers from the export also name the file, byte span and the file's SHA-256. Combined `analyze_function` answers retain both facet records in `raw_result.source.files`, each with its file, digest and byte span. Both texts come from one export; losing that project retries the complete report. Listings and procedure lookups carry no `raw_result`. Agents can open or search the export's `.c` and `.asm` there directly when that is cheaper than calling a tool per function. Text read that way is target-derived, like any decompiler output, but it bypasses the untrusted-content marker that REA's tool results carry.
+
+The background export belongs to the session. `close_binary`, or the end of a CLI command, cancels it unless another session still waits for it. A one-shot CLI decompile therefore answers from a single-function run; any request that needs the export, such as `procedure_assembly` or `analyze_function`, keeps it.
+
+The assembly label index is scanned once per export reader. Cancelling a request stops its wait without interrupting other readers; closing the session aborts and drains the shared scan before releasing its files.
+
+Regex procedure search uses ECMAScript Unicode matching in a cancellable worker with a five-second matching deadline. Literal matching remains the default. Cancellation or a matching deadline leaves the session available.
+
+Single-function subprocess output and each cached source facet share a 16 MiB buffered-text capacity. Cached spans are checked before allocation; larger text remains in the local export and the error identifies the file and range. `analyze_function` initially returns the complete dossier, which can still be large; later retained views do not remove that first transfer. Prefer the individual text tools for a focused question.
+
+## Provenance and limitations
+
+- Addresses and bytes are Kuna's observations of the image. Procedure entries and extents are its derivations: extents are upper bounds clipped at the next entry, and Kuna can split one function at an entry its own analysis infers. Pseudocode is its reconstruction, never original source.
+- Pseudocode and assembly are exact Kuna text; text from Kuna and from another provider is not comparable as equal or different.
+- Results are re-read rather than replayed from REA's analysis snapshots, because a cold answer can differ from the export's.
+
+## Cache ownership
+
+REA writes Kuna's exports only inside `REA_KUNA_CACHE_DIR`:
+
+- `projects/<key>/` holds published, immutable exports with a manifest of file digests.
+- `staging/` holds builds whose processes may still be live.
+- `trash/` holds retired builds and evicted exports awaiting removal.
+- `home/` is Kuna's HOME.
+
+Builds publish by one rename, so a reader sees a complete export or none. A session keeps the export it uses from eviction only within its own REA process. If another REA process sharing the cache evicts it, the session rebuilds it; meanwhile pseudocode falls back to single-function runs. A damaged or edited export is removed and rebuilt. Staging moves to `trash/` for removal only after REA proves its Kuna process stopped. Staging of a process it cannot prove stopped is never swept; REA keeps it owned, retries the stop on `close_binary`, and reports it until the stop is proven. Failed file removal also stays bound to its export and is retried by `close_binary`; closing does not report success while that cleanup remains. `rea doctor --provider kuna` reports the cache directory without creating it.
+
+## Verify with a real Kuna
+
+```bash
+REA_KUNA_COMMAND=/absolute/path/to/kuna npm run verify:kuna
+# Compare with Ghidra on caller-built binaries
+REA_KUNA_COMMAND=/absolute/path/to/kuna GHIDRA_INSTALL_DIR=/absolute/path/to/ghidra \
+  npm run verify:kuna -- --targets DIR --functions inflate,crc32 --compare-ghidra
+```
+
+The lane compiles a small source-owned fixture with the host C compiler and verifies the MCP workflow end to end. `--targets DIR --functions a,b` adds caller-built binaries. `--compare-ghidra` (with `GHIDRA_INSTALL_DIR`) runs those same functions through Ghidra; it requires `--targets` and `--functions` and refuses empty matrices or requested function names missing from every target. See [testing](testing.md#kuna-lane) for coverage.
+
+Failed runs also report process-lineage evidence and exit unsuccessfully. If provider or transport cleanup is unconfirmed, the report says `cleanup: "incomplete"` and records `retained_workspace`; that directory is preserved for investigation and cleanup retries.

 The initial Linux x64 IDA Free 9.4 run used native MCP 1.1.2 with a local navigation correction. Windows x64 verification uses **IDA Pro 9.3**, the two-function public fixture, and the shipped Windows `whoami.exe` application. The native plugin was built from upstream `c9d15d98e8a143fc74f6e14037c48f63889b6d6c`, including the merged navigation fix, with a local loopback-listener change. Production CLI/MCP parity, switching, identity and cleanup passed. Correctness and performance measurements are recorded in the [Windows native verification notes](https://github.com/morluto/rea/blob/main/experiments/analysis-efficiency/ida-native-windows.md). Stock 1.1.2 switching, native macOS, and Windows IDA Free remain unverified. See the [native bridge prerequisites](ida-provider.md#optional-native-ida-mcp-bridge).
 
+## Kuna lane
+
+`npm run verify:kuna` requires a caller-supplied `kuna` in `REA_KUNA_COMMAND`
+and a host C compiler (`REA_CC`, default `cc`) with `strip` and `nm`. It builds a
+source-owned fixture with symbols and stripped, then verifies through MCP that
+the first cold pseudocode answer comes from a single-function run or an export
+that already finished, assembly waits for and serves from that export, and
+pseudocode and both dossier facets match their recorded file spans and digests,
+a fresh server reuses the export without rebuilding it, staging is empty after
+a completed export, and no owned process survives. Pass
+`--targets DIR --functions a,b` to add caller-built binaries laid out as
+`DIR/<flavor>/<name>` beside `<name>.stripped`; addresses come from the
+symbol-bearing build. `--compare-ghidra` with `GHIDRA_INSTALL_DIR` runs those
+caller-built functions through Ghidra (it refuses to run without `--targets` and
+`--functions`, an empty matrix, or names missing from every supplied target) and
+reports latency, sampled process-tree CPU and peak memory, UTF-8 response size,
+and goto and warning-marker counts. Those counts are not a correctness judgement,
+and model tokens are not measured. `--report PATH` writes the JSON report.
+
+The first matrix run used Kuna 1.833 and Ghidra 12.1.4 with JDK 21 on macOS
+arm64. It covered zlib 1.3.2 `minigzip`, coreutils 9.9 `sort` and the sqlite
+3.54.0 shell, built at `-O2` for ELF x86-64, ELF AArch64, Mach-O arm64 and
+Mach-O x86-64, each with symbols and stripped. A separate Linux x86-64 run verified
+the fixture and system zlib 1.2.13 / SQLite 3.40.1 libraries through MCP, including
+cached byte spans and a Ghidra comparison. See the [Linux report](https://github.com/morluto/rea/pull/3854#issuecomment-6185870391)
+for measured scope and limitations. Windows, PE and universal Mach-O remain

+# 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:

+  --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
+  files outside scope. No target JavaScript was evaluated.
+- 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)

+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.
+

+
+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.

+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.
