+    "collection": "modules",

+```
+
+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
+`d1ed428c363968774f0f3906e67d8a53a058ece0b6cdd924b07865977b2ada21`;
+ASAR 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
+```

+  "question": "For a packaging/sandboxing review of the actual shipped Obsidian main.js, inventory every retained javascript-module identity at that exact path and inspect its item facts. 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."

Offsets follow the selected parent record order, preserving original producer ordinals. Paging never reopens the source or reruns the decoder. For inspect_pcap_capture parents, kind pcap pages endpoints, dns-queries, tls-sni, protocols, http-uris or unattributed-addresses. Select an exact query for dns-addresses, or a tshark/capinfos stream for UTF-16 diagnostics text. Page totals count retained facts; source coverage remains explicit. Qlog summaries keep profile/scope and counts; kind qlog pages traces, streams, loss-declarations, incomplete-records, contributions, ranges or final-sizes. Except traces, select trace_index; stream-specific facets also require exact stream_id and direction. Facts retain all-recorded-events-before-selection scope, and interval overlap or endpoint loss declarations do not prove retransmission or network loss. The api-surface view groups retained HAR requests by method, origin and format-rule path template; templated segments are inferences. It reads no headers or bodies and reports no query values. For a retained record use source: {kind: "retained-evidence", evidence_id: "<parent_evidence_id>"}. Use normalized_result.parent_evidence_id from a summary receipt. Source kind is required. Portable source uses {kind: "inline", evidence: <complete Evidence>}. For layout, JavaScript, inventory, WASM, Mach-O, Interface Builder, EVM, managed artifact, Android package and Dart AOT sources, request a summary with view: {kind: "summary"}; summary is a view kind and has no facet. The WASM summary gives validation, counts, WAT digest/length, tool profile and execution/network states without reading WAT text. Select a layout mitigations/linkage facet, one section/symbol/module, or a stable page. Module pages include assets, bundled and source modules; use node_id for ambiguous or unavailable paths. Inventory uses view: {kind: "inventory", collection: "occurrences", logical_paths: ["package.json"], offset: 0, limit: 64}. Inventory views page nodes, occurrences, edges or integrity contradictions; occurrence logical_paths matches exact recorded strings (omitted means all available, [] means none). source_complete distinguishes complete inventories from partial source records; page exhaustion does not prove absence in a partial source. WASM views use kind wasm and facet sections/imports/exports/candidates/glue/wat/headers/details/tool_profile; text facets use UTF-16 code units and source forms remain exact. Mach-O views use kind macho and facet entrypoints/architectures/build_metadata/load_commands/dependencies/imports/exports/segments/provenance; source_exhaustive false means unreturned rows may exist. Interface Builder views use kind interface-builder and collection documents/nodes/edges/coverage; nodes and edges accept an exact document relative_path. EVM summary returns all inferred interface candidates, carrier/decoded identities and explicit unknowns without hex or duplicate stdout. EVM views use kind evm and facet functions/bytecode_hex/stdout/stderr; function pages preserve the original candidate rows, and text offsets/limits count UTF-16 code units (hex has two characters per decoded byte). Exhausting candidate pages does not establish global interface completeness. Managed artifact summaries preserve complete identity/classification, metadata status, module/MVID, frameworks, coverage and limitations without unrelated inventories. Managed pages use kind managed and collection references/resources/attributes, retaining source coverage and build-local token scope; page exhaustion does not establish complete metadata. Managed member summaries keep identity, selection with unmatched names, coverage and per-collection counts; managed-members pages use collection types/exported_types/fields/methods/member_refs/call_edges/field_accesses/user_strings and carry the source selection and coverage. Android package summaries retain all declarations, engine identity and counts without decoded manifest text. Android manifest pages use kind android, facet manifest, offset and limit in UTF-16 code units; source_status preserves partial decoded coverage even when the retained text page is exhausted. Dart AOT summary preserves target/ABI/library identity, snapshot headers and pool lower bounds. String pages use kind dart-aot, collection package_uris/dart_uris/class_like_tokens; source coverage remains partial when the producer says partial. Native function Evidence requires kind native: view: {kind: "native", facet: "procedure"}. Facets select procedure, pseudocode, assembly, basic blocks, comments, callers/callees, references, unresolved calls, referenced strings/names, native API and high-pcode. Use nonnegative offset and a positive caller-selected limit (defaults 0 and 64); pseudocode uses UTF-16 code units, other native pages use rows.
