feat(recall): trust/provenance term in WRRF fusion (#368) - #399

cdeust · 2026-08-09T08:56:43Z

Closes #368 (when the calibration lands — see Not ready to merge below).

What this adds

A trust/provenance term in the WRRF fusion, so a candidate whose origin is
untrusted can be demoted at ranking time. The mechanism is complete and green
on both backends, and inactive in production: UNTRUSTED_ORIGIN_FACTOR
defaults to 1.0 (identity — it demotes nothing) until the calibration below
picks a value.

Entry measurement: 4/4 adversarial attacks succeeded. Cheap pre-sweep:
W=1.0 → 0/4 defended, 0.95–0.80 → 2/4, W ≤ 0.70 → 4/4.

Commits

8d4e92fe — the mechanism
64a35ca8 — split pg_recall.py at its two documented seams (the
craftsmanship gate blocked on pre-existing debt in a file this touches)
5177cf32 — sweep: empty-array expansion under set -u (bash 3.2)
66d2628f — benchmark harness fix, see below

The harness fix is the load-bearing part of this push

reproduce.sh::start_db() waited on pg_isready over the container's Unix
socket. The postgres entrypoint runs initdb against a socket-only temporary
server (listen_addresses=''), so the socket reports ready during
initialization and the benchmark's own connection from the host is refused.
It killed 3 of 5 calibration cells in ~3s each. Loud failures (rc=1) — no cell
produced wrong numbers, only no numbers.

Probing TCP inside the container was tried first and rejected by
measurement (optimistic too, median 2.06s, 5/5 runs). The probe is now the
real thing: a psycopg connection from the host over the published port.

Full measurement, the entrypoint evidence, and the two errors made while
measuring (ordering bias; locale-truncated awk) are recorded in
docs/provenance/pg-readiness-probe-2026-08-09.md.

This dragged reproduce.sh further past the §4 size limits it already
violated, so per the boy-scout rule it was split: container lifecycle →
benchmarks/lib/bench_container.sh, MANIFEST heredoc →
benchmarks/lib/write_manifest.py (now lint-checked like the Python it always
was). 621 → 440 lines, no function over 50. Verified behaviour-preserving:
identical scores (MRR 0.8439, R@10 0.9746) and an identical MANIFEST on every
non-volatile field.

This is why CI matters on this PR — it exercises the release gate harness
itself.

Not ready to merge

The calibration grid {1.0, 0.8, 0.7, 0.6, 0.5} is re-running now (~7h) on
the corrected harness. The first attempt is discarded in full — including the
cell that completed — because a grid cannot mix provenances.

Remaining before this leaves draft:

apply the pre-registered rule (largest W defending 4/4 with all four
reproduce.sh floors intact) — unchanged, not reinterpreted
fill §Results in docs/provenance/trust-factor-calibration.md
wire that W with a # source: pointing at the pre-registration
if no W satisfies both, no floor gets relaxed — it comes back for a
decision

Out of scope, filed rather than fixed: pg_store.py is 1384 lines.

recall fused relevance and salience only, so a poisoned memory crafted to win on similarity outranked a good one, and heat compounded the win on every retrieval. Adds a capture-origin trust factor to the ranking itself, per arXiv 2604.16548 ("Retrieval-time filtering alone is insufficient"). - adversarial corpus (4 attack families) shared by tests and the ablation; measured before the fix: hostile entry ranked 0, legitimate 1, 4/4 - ORIGIN_LEGACY + one-shot backfill inside the migration's creation branch, so the pre-#365 corpus keeps full weight while post-upgrade unclassified rows stay 'unknown' and are demoted - multiplicative factor before ORDER BY on both backends (PG trust_weighted CTE; SQLite _apply_trust_factor, where no such chain existed) - heat feedback loop broken for untrusted origins, positive delta only, so cooling still applies and access bookkeeping is untouched - capture_origin added to the WRRF candidate contract and its SA producer The trust policy is passed to infrastructure, never imported by it (layer rule), so core/capture_origin.py stays the single source of truth. All defaults are the identity transform: the production weight is not wired yet — it must come from the ablation sweep, not from a chosen constant.

pg_recall.py stood at 833 lines against the 500-line §4.1 limit, and the craftsmanship gate blocks any commit touching it — including the five-line trust-policy wiring #368 needs. Split rather than exempted. Both seams were already marked in the file by its own section banners, so this follows the structure the code claimed rather than inventing one: - pg_recall_assembly.py (287 l.) — the budgeted, slot-filled 3-phase context assembly that CONSUMES recall's output. Changes when the prompt budget or stage model changes. - pg_recall_weights.py (116 l.) — intent-adaptive WRRF weight profiles. Changes when retrieval is recalibrated. - pg_recall.py (498 l.) — recall orchestration, and a facade re-exporting both so no caller or test had to move (same pattern as synaptic_plasticity.py). Assembly imports recall lazily inside the one function that calls it: the runtime dependency is genuinely one-directional (assembly -> recall), and a module-level import would close the cycle the facade creates. Every value moved unchanged — this re-homed code, it retuned nothing. Verified by the same 4469-test invocation used before the split, with the identical count passing. Also wires UNTRUSTED_ORIGIN_FACTOR into the production recall path; it stays at the identity (1.0) until the pre-registered sweep reports.

The no-argument path (the full grid — the one that matters) died on cell 1 with "EXTRA_ARGS[@]: unbound variable". macOS ships bash 3.2, where expanding an empty array under `set -u` is an error; the --quick smoke that validated the plumbing never hit it, because that path filled the array. Carried as a plain string, left unquoted at the call site so it word-splits to zero arguments when empty.

…rking start_db() waited on `pg_isready` over the container's Unix socket. The postgres entrypoint runs initdb against a socket-only temporary server (docker-entrypoint.sh: "does not listen on external TCP/IP", listen_addresses=''), so the socket answers "ready" during initialization, the loop exits early, and the benchmark's own connection from the host is refused. This killed 3 of the 5 cells of the issue #368 trust-factor sweep in ~3s each. Failure was loud (rc=1) — no cell produced wrong numbers, only no numbers. Probing TCP inside the container was tried first and rejected by measurement: it is optimistic too (median 2.06s early, 5/5 runs). Only a psycopg connection from the host over the published port is a valid probe, so that is what both harnesses now wait on. The loop also fails loudly if the container exits during startup instead of spinning forever. Measurement, the entrypoint evidence, and the two harness errors made while measuring (ordering bias, locale-truncated awk) are in docs/provenance/pg-readiness-probe-2026-08-09.md. Carried with it, per the boy-scout rule, because the fix pushed reproduce.sh further past the coding-standards.md §4 limits it already violated: - container lifecycle -> benchmarks/lib/bench_container.sh, with start_db()'s wait split out as wait_for_db() - the MANIFEST.json heredoc -> benchmarks/lib/write_manifest.py, which is now lint-checked like the Python it always was (the noqa sites carry the per-site justification tool.ruff.lint requires) - reproduce.sh 621 -> 440 lines, no function over 50 Refactor verified behaviour-preserving: `reproduce.sh --only locomo --quick` returns bit-identical scores before and after (MRR 0.8439, R@10 0.9746, same per-category figures) and a MANIFEST.json identical on every non-volatile field, with the reranker loaded. The affected sweep is discarded in full — including the cell that completed — since a grid cannot mix provenances. Re-run pending.

I2's ALLOWED_WRITERS pins line numbers. 8d4e92f (#368) added 8 net lines above every heat_base site in sqlite_store.py — the COLUMN_BACKFILLS import and _run_column_migrations' `except OperationalError: pass` becoming `continue` + a conditional backfill execute — so 549/579/643 moved to 557/587/651. Same three writers, byte-identical SQL: each site was diffed against origin/main before re-pinning, and the scanner reports zero unexpected and zero stale entries after the change. No new writer is introduced and none is being silently authorised; the test remains the oracle, as on every prior re-pin recorded in this file. This is what turned the whole Linux test matrix red on PR #399 while every other job stayed green — the Windows job passes because it deliberately runs six targeted portability/backend files, not tests_py/invariants/.

The demotion weight shipped as the identity (1.0) and demoted nothing: the mechanism was complete but inactive, pending the pre-registered sweep. The sweep has now reported on both of its arms, so the constant is sourced and the control applies. Decision rule applied verbatim (largest W defending 4/4 adversarial scenarios while every gated floor holds); no floor was relaxed: - adversarial arm RE-MEASURED. docs/provenance §Grid carried its table in prose with no committed artefact, so half the rule rested on a number nobody could reproduce. benchmarks/lib/trust_factor_sweep.py measures it over the same points and confirms the table exactly, 0.80 -> 0.70 transition included: 1.0 -> 0/4, 0.95-0.75 -> 2/4, 0.70-0.20 -> 4/4. This also fills the dead reference the constant's comment pointed at. - gated arm: 5 reproduce.sh cells, one provenance (git_sha 66d2628, same dataset sha256, reranker loaded), 20/20 floor checks PASS. At W=0.7, LME 0.9820/0.9178 and LoCoMo 0.9329/0.8181. §Results records what the grid does NOT establish: the benchmark harnesses never set capture_origin, so every candidate takes the 'unknown' default and W rescales them uniformly, leaving the WRRF order invariant (LME identical to four decimals across the grid). The floors prove non-regression, not the absence of a relevance cost under mixed origins. Two provenance corrections are recorded there too, rather than smoothed over: the cells ran with consolidation OFF (reproduce.sh never passes --with-consolidation), and the pre-registration's "OFF scores ~0%" claim belongs to run_benchmark.py.

CodeQL's py/clear-text-storage-sensitive-data flagged the benchmark artefact write in benchmarks/lib/trust_factor_sweep.py:179. The value it calls a secret is the constant triple ("deliberate", "legacy", "local_action") — the read-time trust allowlist of #368, defined as public string literals at capture_origin.py:66-70. The classification comes from the identifiers containing "trusted", not from the value, and CodeQL classifies the alert itself as "test". Alert 143 is dismissed as a false positive; SECURITY.md now carries the checkable rationale and the re-open trigger, in the same shape as the Scorecard Code-Review dismissal (#126). No production identifier was renamed to satisfy the scanner. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01263uv1QqR8TVzw2jXYUrXn

ZETETIC-REVIEW: APPROVE

Review performed 2026-08-09 by the zetetic code-reviewer agent, in a fresh context, on git diff origin/main...feat/issue-368-trust-provenance-wrrf (7 commits). Posted here because a verdict that lives only in a chat transcript is not a record — and because this PR was previously described as ready on the strength of a green CI alone, which is not a verdict of validity.

Verdict

Valid as-is. Every sourced claim checked — the # source: chain from mcp_server/core/retrieval_dispatch.py:23-41 through docs/provenance/trust-factor-calibration.md to the committed artefacts under benchmarks/results/trust-factor-sweep/ — traced to real data matching what the comment asserts. The specific vice rejected on PR #403 (a # source: citing a path that exists only on the developer's machine) does not recur here.

The adversarial corpus is a genuine test, not a staged result: Gram-Schmidt-constructed embeddings run through the live ranking path, four distinct attack families, defended counts re-measured and reproduced twice. The calibration document is unusually candid — it states its own limitation rather than smoothing it over, and corrects an earlier drafting error about --with-consolidation instead of quietly editing it away.

The caveat that governs how this should be read

The gated floors prove non-regression under uniform capture origins, not the absence of relevance cost under mixed ones. The harnesses never populate capture_origin, so W multiplies every row alike and cannot change any ordering — which is why LongMemEval is identical to four decimals. The question this PR settles is narrower than it appears to settle. That is disclosed in the calibration doc, and now has a follow-up: #405.

Non-blocking findings

mcp_server/core/pg_recall.py came out of its split at 494 lines: under the 500-line global cap, over this repo's stricter 300-line local cap, which the split commit's own message did not cite. Filed as pg_recall.py is 494 lines — under the 500 global cap, over this repo's 300-line local cap #404.
The mixed-origin limitation had no follow-up issue. Filed as Trust factor W=0.7: the mixed-origin relevance cost is disclosed but unmeasured #405.

Neither blocks the merge.

…ng_ages 59 lines, three other >40-line methods Three findings from PR #409 review round 1, verified against a fresh clone before this fix (not before): 1. pg_store_search.py measured 301 lines — one over the 300-line §4.1 cap. The PR body reported 280, which was true before the rebase but not re-measured after the #399 trust-term port added 18 lines. Split the downstream-signal methods (spread_activation_memories, get_hot_embeddings, get_embeddings_for_memories, get_temporal_co_access) into a new pg_store_signals.py — recall/FTS/ vector-search stay in pg_store_search.py, now 229 lines. 2. get_grooming_ages (pg_store_stats.py) measured 59 lines against a claimed "every method <=40 lines". The three near-identical tag-prefix-age blocks (wiki/distillation/promotion) share one parameterized helper, _grooming_tag_prefix_age(prefix); the LIKE pattern is now a bound parameter instead of a literal-interpolated suffix (same match semantics, standard psycopg parameterized LIKE). 3. Re-swept every file this PR creates or modifies (not just the ones already reviewed) and found three more over-cap methods introduced by the #407 split, missed because the earlier method-length check covered only the pg_store.py-split family, not pg_store_queries.py/ pg_store_query_stream.py's post-split content: search_by_tag_vector (43 lines, pg_store_queries.py) split into _search_by_tag_vector_ranked/_unranked; iter_hot_memories_chunked and iter_memories_for_decay (both pg_store_query_stream.py) each split into a helper carrying the per-page/per-cursor mechanics. No logic change in any of the four — same SQL, same bind order, same control flow, just named helpers. Fixing the nesting depth in the extracted _stream_decay_cursor_chunks required combining three nested `with` statements into one (`with a, b, c:`) — the pre-commit hook's NESTING_TOO_DEEP check (coding-standards §4.5, max 3) flagged the verbatim-relocated body at depth 5; same semantics (same three context managers, same order), shallower syntax. Re-measured after these fixes, not before: zero files over 300 lines, zero methods over 40 lines across every pg_store*.py file this PR touches. Three pre-existing over-40 methods remain in sibling files this PR does not modify (pg_store_entities.py::insert_entity 43, pg_store_entity_merge.py::merge_entities 81, pg_store_relationships.py::reinforce_or_create_relationship 86) — verified via `git diff origin/main` showing zero diff on those three files; out of this PR's blast radius, not claimed as compliant. Full suite: 7270 passed, 147 skipped, 0 failed. ruff check + format clean. pyright zero-diagnostic on mcp_server/. Item 2 from the same review (fabricated citation excusing the wiki_store.py/wiki_schema_reader.py layer violations by misattributing them to CLAUDE.md's documented list, which covers the opposite direction and different files) is addressed in the PR description, not a code change — see that update for the honest accounting.

… fix infra->core layer violation (#409) * refactor(infra): split pg_store.py (1384 lines) into concern-scoped mixins pg_store.py exceeded the local 300-line §4.1 cap by 4.6x. Split behind the existing pg_store_host.py PgStoreHost contract pattern (the same shape workflow_graph_source_ast.py used for #275 and core/context_assembly/condensers.py used for #228: thin facade + re-export, leaf modules by responsibility): - pg_store_schema.py — connection creation + Phase 5 pool lifecycle - pg_store_ddl.py — pooled query execution (_execute) + DDL migration (_init_schema); module-level compute_ddl_hash/read_schema_hash/ _get_database_url re-exported from pg_store.py for mcp_server.migrate - pg_store_serialize.py — embedding<->bytes, datetime normalization, row shaping - pg_store_write.py — memory INSERT path (SQL constant + param building + commit) - pg_store_supersede.py — atomic reconsolidation-supersession (chain-head CAS + anchor transfer inside one transaction — boundary untouched) - pg_store_heat.py — A3 heat_base writers + homeostatic factor - pg_store_memory_meta.py — single-row metadata writers + mood + compression - pg_store_search.py — recall/FTS/vector search + server-side signals PgMemoryStore's public API is unchanged: same class, same method names/signatures, same import path. pg_store_host.py's PgStoreHost TYPE_CHECKING contract gained the new cross-mixin members (interactive_pool, acquire_interactive, _bytes_to_vector, _vector_to_bytes, _isoformat_datetime_fields, _insert_memory_on). Four methods exceeded the local 40-line cap pre-split (_init_schema, _build_insert_params, supersede_atomic, recall_memories) — each split into named helpers with no logic change (e.g. _build_insert_params's 33-key dict now assembled from two merged sub-dicts; supersede_atomic's per-attempt transaction body extracted to _supersede_attempt, same transaction boundary). _deallocate_all/_reconnect/_execute_on_conn/_init_schema keep the explicit "mcp_server.infrastructure.pg_store" logger name (not __name__) so log output is unchanged for any external log-name filter. test_I2_canonical_writer.py's line-pinned heat_base writer allow-list updated for the 3 relocated sites (bump_heat_raw, update_memories_heat_batch, _transfer_anchor_on) — same writers, no new ones. test_s110_sweep_ infrastructure.py's register_vector monkeypatch retargeted to pg_store_schema (where _reconnect now lives). Verified: full suite 7233 passed / 147 skipped / 0 new failures (2 pre-existing agent_briefing failures, unrelated — issue #400, open fix in PR #403), ruff check + format clean, pyright zero-diagnostic on mcp_server/, all 9 resulting files <=300 lines, all methods <=40 lines. benchmarks/reproduce.sh --quick (LongMemEval-S, LoCoMo, BEAM-100K) byte-identical before/after: LoCoMo MRR 0.8195/R@10 0.9543, BEAM-100K MRR 0.6558/R@10 0.8500, LongMemEval-S MRR 0.850/R@10 100%. Filed (not fixed, out of blast radius): issue #406 — infrastructure/ importing core/ at 6 sites (pg_store_write.py's relocated core.temporal_normalize import among them), pre-existing since 2026-07-29, also present in untouched sqlite_store.py/pg_store_near_dup.py/ pg_store_memory_reheat.py.

Four infrastructure/ files needed temporal_normalize.normalize_date_to_iso, near_dup_calibration.SCAN_FLOOR/CandidatePair, or write_class.classify_write_class directly (pg_store_write.py, pg_store_near_dup.py, pg_store_memory_reheat.py, sqlite_store.py) and could not legally import them from core/. Root cause: temporal.py, temporal_normalize.py, temporal_timezones.py, near_dup_calibration.py, and write_class.py are pure business-rule-free utilities — stdlib-only imports (math/re/datetime, collections.abc/typing, NamedTuple), zero I/O, zero dependency on any other core/ module's business logic (temporal_normalize.py depends only on its sibling temporal.py/temporal_timezones.py, which moved with it). They satisfy shared/'s own stated criterion ("pure utility functions... no dependencies on other project layers") and were simply filed under the wrong layer. Fix: relocated all five to shared/, updated every import site across core/, infrastructure/, handlers/, tests_py/, scripts/, and benchmarks/ (22 files) — both `from mcp_server.core.X import Y` and `from mcp_server.core import X` forms. docs/module-inventory.md updated: entries moved from the core/ section to shared/, dependency counts re-measured and sourced. tests_py/invariants/test_I2_canonical_writer.py: homeostatic_apply.py's line-pinned heat_base writer shifted 233->234 (one new `from mcp_server.shared import write_class` import line above the site). Same writer, not new. Verified: full suite green (see subsequent commits' final run), ruff check + format clean, pyright zero-diagnostic on mcp_server/. No functional change — every relocated symbol keeps its name and signature; only the import path changes.

Two small opportunistic cleanups while relocating (both behavior-preserving): insert_archive and get_all_memories_with_embeddings now call `self._bytes_to_vector` / `self._vector_to_bytes` directly instead of a deferred `from mcp_server.infrastructure.pg_store import PgMemoryStore` — unneeded now that the methods live in a mixin composed alongside PgSerializeMixin. docs/module-inventory.md's infrastructure/ section fully re-catalogued for the 16 pg_store_*.py modules now in the facade's mixin family (was "pg_store.py — PostgreSQL + pgvector persistence" as a single line); file counts re-measured.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01263uv1QqR8TVzw2jXYUrXn * fix(infra): eliminate wiki_store.py/wiki_schema_reader.py -> core/ layer violation at the root cause Review round 3 rejected declaring this violation with a documented rationale as sufficient — a stated exception is a confession, not an acceptance criterion. The actual defect: wiki-generation domain logic was mixed with storage access in infrastructure/wiki_store.py, so neither could move without the other. This commit undoes the mixing instead of re-justifying it. Two fixes, chosen per Move (b) vs Move (a) by what each import actually needed, not by which was easier: 1. shared/ move (8 modules, same rationale as #406's core->shared move): wiki_frontmatter.py, wiki_page_builders.py, wiki_index.py, wiki_pages.py, wiki_layout.py, wiki_readme.py, wiki_frontmatter_validation.py, wiki_schema_loader.py are all stdlib-only, zero I/O, no dependency on any other core/ business logic — verified by reading every one of their imports, not assumed. infrastructure/wiki_store.py and wiki_schema_reader.py needed these directly for page parsing/templating/frontmatter normalization, none of which is a policy decision. 2. Ports-and-adapters (ports core/ declares, composition root wires): core.wiki_sync.build_from_memory runs the v2 classifier — real domain judgment (which wiki kind, which directory, whether the memory qualifies at all), not a pure helper, and it transitively touches disk via wiki_axis_registry's already-reverse-DI'd lazy registry cache. wiki_store.py's sync_memory_strict/sync_memory (the functions that called it) moved to a new composition root, mcp_server/handlers/wiki_memory_sync.py — the layer that is legally allowed to import both core/ and infrastructure/ and wire them together. wiki_store.py itself now only exposes pure I/O primitives (write_page/read_page) and imports nothing from core/. Boy-scout, surfaced while touching this file: wiki_store.py was 439 lines, over the 300-line §4.1 cap, pre-existing before this fix. Split along the boundary this fix already created: wiki_store.py (234 lines, read/write primitives) + wiki_pages_listing.py (append_section/ list_pages/next_adr_number, cross-module callers updated: wiki_verify, wiki_migrate, wiki_list, wiki_reindex, wiki_adr, and the test suite) + wiki_reindex_io.py (try_reindex/cleanup_id_prefixed_pages, moved out of wiki_store.py's private `_try_reindex` — renamed public, since it now has a real cross-module caller in wiki_memory_sync.py). The two sanitizer helpers callers needed cross-module (safe_join, _atomic_write_bytes) were made public/relocated rather than reached into as private names. Verified: grep -rn "from mcp_server\.core\." mcp_server/infrastructure/*.py # empty — zero infrastructure/ -> core/ imports anywhere, no # residual violation declared or otherwise. Full suite: 7270 passed, 147 skipped, 0 failed. ruff check + format clean. pyright zero-diagnostic on mcp_server/. Every resulting file <=300 lines, every method <=40 lines (wiki_store.py 234, wiki_pages_listing.py 100, wiki_reindex_io.py 88, wiki_memory_sync.py 95). docs/module-inventory.md fully re-catalogued for the 8 shared/ moves, the 3-way wiki_store.py split, and the new composition-root module; file counts re-measured and sourced. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01263uv1QqR8TVzw2jXYUrXn * fix(infra): complete the wiki layer-violation fix (remaining call-site updates) Continuation of 1e2b11b: that commit's staging missed most call-site updates (a multi-path `git add` aborted atomically on one bad pathspec, silently leaving everything after it unstaged — caught by re-checking `git status` post-commit rather than assuming the commit was complete). This commit adds every file the wiki_pages/wiki_layout/wiki_schema_loader core/->shared/ move and the wiki_store.py split actually touched: core/wiki_groomer.py, wiki_rule_engine.py, wiki_sync.py, draft_compiler.py, draft_curator.py, draft_synthesizer.py; handlers/wiki_adr.py, wiki_compile.py, wiki_list.py, wiki_migrate.py, wiki_reindex.py, wiki_synthesize.py, wiki_verify.py, wiki_write.py, remember.py, consolidation/page_io.py, ingest_findings_writers.py; infrastructure/wiki_schema_reader.py, wiki_store.py; scripts/wiki_bulk_migrate.py, wiki_rebucket_file_docs.py; the full wiki test suite; and docs/module-inventory.md. No content change from what was already verified in 1e2b11b — full suite (7270 passed, 0 failed), ruff, and pyright were run against the complete working tree before either commit; this only fixes which commit those files landed in. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01263uv1QqR8TVzw2jXYUrXn * fix(infra): round 4 — measure-then-write on the 13 wiki files this PR touches; correct stale CLAUDE.md claim Review round 3 caught a repeating pattern across three consecutive rounds: asserted compliance the PR body had not actually re-measured after the last edit (301-line file reported as 280; a 59-line method claimed under the cap; four >40-line methods in files this PR had just moved and re-documented). The order for this round is reversed per review instruction: measure first, fix, re-measure, write the PR body only from the final numbers. AST sweep of the 13 files this PR creates or moves (the shared/ wiki_* cluster, the wiki_store.py split, wiki_memory_sync.py) found four over-40-line methods, all in material this PR's own docstrings claim to have touched (moved core/ -> shared/, added Layer-note paragraphs): - wiki_frontmatter.py::parse_page (63) — extracted _parse_frontmatter_body (the key/value loop) and _collect_block_list (the block-list lookahead); parse_page is now the guard-checks + delegate shell its docstring already described it as. - wiki_index.py::build_index (70) — extracted _parse_page_entries, _group_by_domain_kind, _render_domain_section; build_index composes the three, unchanged output. - wiki_readme.py::build_plain_readme (104, more than double the generic 50-line coding-standards.md §4.2 cap) — extracted one render helper per section (_render_readme_header/_render_whats_here/ _render_domains/_render_navigation_and_contributors); same lines emitted, same order. - wiki_schema_loader.py::parse_rules_table (41) — extracted _parse_rule_row (per-row cell parsing + validation); the table-scan loop is now a generator expression filtered by `is not None`. No behavior change in any of the four — same inputs produce the same markdown/dataclasses; verified by the unchanged full-suite result. Also corrected (reviewer-flagged): CLAUDE.md's "Import rule" bullet named `wiki_axis_registry.py`/`wiki_classifier.py`/`wiki_schema_loader.py` as 3 pre-existing core/->infrastructure/ violations (found 2026-07-14, #114). Verified false as of this measurement: `grep -rn "from mcp_server.infrastructure" mcp_server/core/*.py` returns nothing — `wiki_schema_loader.py` no longer lives in `core/` (this PR moved it to `shared/`) and the other two do not import `infrastructure/`. The bullet now states both grep commands (both directions) and the measured-clean result, dated, instead of a stale named list. Final measurement (this commit, run after every fix above, not before): - All 13 files: 0 over the 300-line file cap. - All 13 files: 0 methods over the 40-line cap. - `grep -rn "from mcp_server\.core\." mcp_server/infrastructure/*.py` → empty. - `grep -rn "from mcp_server\.infrastructure" mcp_server/core/*.py` → empty. - Full suite: 7270 passed, 147 skipped, 0 failed. - ruff check + format: clean. - pyright: 0 errors, 0 warnings, 0 informations.
