fix(install_cc_hook,session_start_hook,tools): preserve wrapper-level metadata, thread Mcp-Session-Id, add manual slider harness - #181
Conversation
…o budget-binding, forward smart subject_key/claim_kind, add SessionStart hook - resolve: honor env_conflict in the strong branch (was honored only by rewrite_gate), with regression test for the long-form staging/production diff path; also narrows temporal_splice to bi-temporal backfill only (valid_at AND subject_key) and removes dead delete+insert merge in _swap_spans; new tests cover marker+proper_swap, marker+heavy_swap, and the closed-predecessor bypass - engine: pass temporal_splice=valid_at is not None and bool(subject_key) to resolve(); engine bi-temporal splice test now uses a subject_key and is paired with a new test_anchored_unkeyed_present_time_stays_live - mcp_server: classic + smart engraphis_recall_context k default 8 -> 50 so the token-budget packer binds on realistic stores out of the box; smart engraphis_remember now exposes and forwards subject_key/claim_kind to the classic tool (the silent drop was a real product bug, all benchmark correction invalidations previously came from the unkeyed fallback leg) - mcp_server: per-call INFO log on engraphis_recall_context with workspace, k, budget, packed/omitted counts, and the call's measured ms - integrations/commandcode: new SessionStart hook (stdlib, fail-open) that calls engraphis_session.start with a generic goal and emits the bounded recall as additionalContext; honors ENGRAPHIS_HOOK_WORKSPACE, ENGRAPHIS_MCP_URL, ENGRAPHIS_HOOK_BUDGET_S, ENGRAPHIS_HOOK_MAX_CHARS - scripts/install_cc_hook.py: idempotent user-scope install/uninstall (with backup) replacing the scratchpad merge_settings.py - tests: smart-mcp-gateway schema tests for subject_key/claim_kind; skill-package Smart-overlap test pins subject_key/claim_kind mention; tests/test_session_start_hook.py covers resolve_workspace, build_additional_context, fail-open paths - skills/.../TOOLS.md + .claude-plugin/skill-assets.sha256: Smart-overlap section now lists subject_key/claim_kind; manifest re-pinned - CHANGELOG: full [Unreleased] entries (Added/Changed/Fixed/Operational) for all four shipped capabilities Bench: hit@5 93.3% (28/30), MRR 0.878, v2 correction invalidations 1/5 -> 4/5 (0/36 false-invalidation regressions), live CLI 5/5 memory vs 0/5 control, default-on savings 0.0 -> 0.4975 (the deep-k path adds ~100ms per call; documented in CHANGELOG).
Three review comments on PR 171, plus matching regression tests.
resolve.py (P1)
- A bare change-marker word ("now", "actually", ...) on a candidate that
shares no subject with the neighbour is not correction evidence — common
words leak into every sentence. The previous rewrite_gate branch treated
`evidence.marker` as sufficient on its own, which let a candidate like
"The production API now uses three replicas" INVALIDATE an unrelated
memory about "Redis caches user sessions" merely because the hash-vector
similarity was >= 0.45.
- New constant `SUBJECT_TOKEN_JACCARD_MARKER_FLOOR = 2` in the marker-only
leg: a change marker can only lift a candidate to INVALIDATE when the
candidate and the neighbour share at least 2 folded subject tokens. The
value-swap leg is unchanged (already required shared_subject >= 2) so
reworded corrections of the same fact still retire their predecessor.
install_cc_hook.py (P2)
- Each SessionStart settings entry is `{"hooks": [{"command": ...}, ...]}`.
The previous idempotency filter used the top-level `h.get("command", ...)`
which never matched the inner shape, so re-running the installer
appended duplicate hooks and every session start performed duplicate MCP
recalls. install() now uses the same nested inspection uninstall() does,
via a small `_session_start_has_our_entry` helper that walks
`wrapper.get("hooks", [])`.
mcp_server.py (P2)
- The recall usage payload never defines `emitted_ms`; the log line
reported `ms=0` for every call. Now captures `time.monotonic()` around
the recall call and logs the real elapsed milliseconds.
Tests
- tests/test_resolve.py: existing `test_reworded_marker_correction_...`
updated to share the same subject, plus a new
`test_reworded_marker_without_shared_subject_does_not_invalidate`
regression test that exercises the reviewer's example.
- tests/test_install_cc_hook.py: 4 new tests covering single-run,
double-run idempotency, non-disturbance of other SessionStart entries,
and uninstall isolation.
All 107 affected tests pass (resolve, mcp_server, session_start_hook,
install_cc_hook); pre-existing engraphis/core/recall.py and dashboard
modifications are unrelated and left for their own review.

…calization, reproducible eval Five review items on PR 171, plus the matching regression coverage: install_cc_hook.py (P2 sibling-hook) - install()/uninstall() now walk the SessionStart wrapper list and strip only our inner entry per wrapper via _strip_our_entry/_strip_our_entries helpers. A wrapper that contained our entry alongside a manually added sibling inner hook keeps the sibling intact across reinstalls; a wrapper that contained only our entry is dropped; a wrapper that did not contain our entry is returned verbatim. install_cc_hook.py (P2 dead constant) - Drop HOOK_KEY (declared at line 23, never referenced). The idempotency check matches on the inner command string instead. install_cc_hook.py (P2 pyright) - main() now narrows __doc__ to a local before calling split(), so pyright no longer reports "split" is not a known attribute of "None". core/resolve.py (P2 env-alias canonicalization) - _ENV_QUALIFIERS now has a sibling _ENV_ALIASES mapping that folds prod/production, dev/development, test/testing, and qa/uat to one canonical form per logical environment. The env_conflict veto in _correction_evidence() compares canonical sets, so a write of "Prod API timeout is 30s" no longer fails the env_conflict veto against a record of "Production API timeout increased to 90s". eval/resolver_reworded_corrections.py + .jsonl (P1 reproducible eval) - New offline-only eval at eval/datasets/resolver_reworded_corrections.jsonl (44 pairs: 38 positives + 6 negatives) and eval/resolver_reworded_corrections.py that drives core.resolve.resolve() over the corpus and reports positives-superseded, false-invalidations, and missed-correction ids. --strict mode returns non-zero so the script can gate CI. Current result: 26/38 positives superseded, 0/6 false invalidations. tests/test_resolve.py (revised marker-evidence contract) - The contradictory "marker alone is enough" vs "marker alone isn't enough" tests are replaced with two clearer ones: test_marker_with_value_swap_invalidates (marker + value_swap on the same shared subject -> INVALIDATE) and test_marker_alone_without_value_swap_does_not_invalidate (marker without a value_swap on the same shared subject -> NOT INVALIDATE). This pins the v1.7 contract: a change marker is necessary but not sufficient for INVALIDATE; it must travel with a value change on the same shared subject. tests/test_install_cc_hook.py - Two new regression tests: test_install_preserves_sibling_hook_in_same_wrapper and test_uninstall_preserves_sibling_hook_in_same_wrapper. Also drops the now-unused `os` and `sys` imports and narrows spec/spec.loader to satisfy pyright strict mode. CHANGELOG.md - Documents the env-alias fold (prod/production, dev/development, test/testing, qa/uat), points at the reproducible eval, and corrects the dataset row counts to the actual 38 positives + 6 negatives. Gates: ruff clean, pyright unchanged (the pre-existing Optional[CorrectionEvidence] errors in core/resolve.py are HEAD-state and out of scope here), 38/38 test_resolve tests pass, 6/6 test_install_cc_hook tests pass, eval reports 26/38 positives superseded and 0/6 false invalidations.

…e branches The strong- and rewrite_gate branches in ``core/resolve.resolve()`` read ``evidence.heavy_swap`` etc. after a single conditional that computed ``evidence`` only when either branch was about to take it. The local was declared ``Optional[CorrectionEvidence]`` so pyright's strict optional narrowing rejected every read. Two minimal patches: 1. Inside the ``if strong:`` block, assert ``evidence is not None`` so pyright can read ``evidence.heavy_swap`` / ``proper_swap`` / ``value_swap`` / ``env_conflict`` after the gate. The ``strong`` branch only runs when ``strong`` was True, and ``strong => evidence was computed above``; the assert documents the invariant for the type-checker without changing runtime behaviour. 2. In the ``rewrite_gate`` guard, lift the ``evidence is not None`` check into the condition itself so the env-conflict comparison doesn't have to defend against ``None``. Equivalent to ``assert evidence is not None and not evidence.env_conflict`` but spelled out so pyright narrows ``evidence`` for the rest of the block. Behaviour is unchanged. Pyright drops from 14 to 0 errors on ``engraphis/core/resolve.py``; all 38 test_resolve tests pass; the eval harness reports 26/38 positives superseded and 0/6 false invalidations on the bundled 44-pair corpus.

The file had been deleted from the working tree (likely by an auto-cleanup process), leaving Command Code sessions with a broken SessionStart hook. The file IS present in the PR1 branch tip; this commit re-stages it so the working tree matches the branch state and the hook is no longer in a transient-deleted state. Verified end-to-end: hook reads stdin, calls engraphis_session.start with reranker-on, emits a 975-byte envelope in 391ms (well under the 8s budget in settings.json).
…ate is clean
The CodeQL gate scripts/check_codeql_sarif.py reported two
``py/polynomial-redos`` findings on ``engraphis/core/resolve.py`` lines
434 and 443, both against ``_ORDINAL_RE.fullmatch(token)``.
The pattern ``\\d+(?:st|nd|rd|th)`` is a classic ordinal-number regex
and is matched against an already-tokenised token, not the raw user
input, so the practical ReDoS surface is bounded. CodeQL's
polynomial-redos heuristic, however, flags any ``\\d+`` followed by a
small fixed suffix as potentially O(n^2) in the worst case, and the
gate's job is to enforce the rule rather than reason about the
actual call site.
Two minimal patches to keep the gate clean without changing
behaviour:
1. ``_ORDINAL_RE`` is now ``\\d{1,10}(?:st|nd|rd|th)\\Z`` -- the
``{1,10}`` upper bound makes the ``\\d`` segment finite so the
regex engine cannot backtrack through a 10-or-more digit run, and
the explicit ``\\Z`` anchor keeps the existing ``re.fullmatch``
call's "match the whole token" semantics.
2. Verified by hand: ``'1st'``, ``'23rd'``, ``'100th'``, and even a
7-digit ``'1000000th'`` all still match; ``'1.0'`` and ``'abc'``
still do not. The 38 test_resolve tests pass; the bundled
resolver eval reports 26/38 positives superseded and 0/6 false
invalidations.

…+ per-call log opt-in
scripts/install_cc_hook.py
- Use HOOK_KEY as the stable identifier for the SessionStart entry instead
of a dead string constant. The `name` field on the entry is set from
HOOK_KEY; the install/uninstall match helpers check it first and fall
back to the legacy command-string match for entries written by older
versions of this script.
- Fix a pre-existing bug surfaced by the new sibling-preservation tests:
install() and uninstall() now filter at the inner-entry level so a
wrapper that contains both an operator-added sibling and our entry
keeps the sibling when ours is refreshed or removed. A wrapper that
contains only our entry is replaced in-place with the fresh entry
rather than being kept as an empty wrapper.
- The install side now refreshes the existing wrapper's entry instead of
appending a second one, so re-running the script is genuinely a no-op
even when a sibling was previously added.
engraphis/mcp_http_cli.py
- Add an opt-in logging.basicConfig that runs only when the operator
sets ENGRAPHIS_MCP_LOG to a truthy value (1 / true / yes / info / on).
Default behaviour is silent so the CLI keeps its quiet profile. Existing
root handlers are never replaced.
CHANGELOG.md
- Mention the ENGRAPHIS_MCP_LOG opt-in alongside the existing per-call
INFO log line on engraphis_recall_context, so operators know the
one env var that turns the logs on.
Tests: 14/14 install_cc_hook + session_start_hook, 22/22 release-infrastructure,
36/36 benchmark-evidence, 4398/39-skip full suite green. Ruff clean. Pyright
clean. Commercial-manifest check clean.
… install/uninstall
install() and uninstall() stripped the wrapper's `matcher` key
because the inner `hooks` list was rebuilt without copying the
wrapper dict first. An operator who added a wrapper-level
SessionStart filter lost that filter on the next install/uninstall.
Two fixes in scripts/install_cc_hook.py:
- _strip_our_entries now shallow-copies the wrapper dict before
writing the trimmed inner hooks list, so any wrapper-level key
(matcher, env, cwd, ...) is preserved.
- _refresh_existing_wrappers mutates the existing wrapper dict in
place (rather than replacing it with a bare {hooks: ...}) so
the operator's wrapper-level keys survive a reinstall.
Also: the uninstall branch that previously dropped a wrapper
became-empty case now has an explicit pass through the original
wrapper, so the comment and the drop decision are co-located.
Tests in tests/test_install_cc_hook.py: two new regression
tests pin the behavior — test_install_preserves_wrapper_level_metadata
and test_uninstall_preserves_wrapper_level_metadata_with_sibling.
Bench: 8/8 test_install_cc_hook.py pass.
…rt hook Stateful transports (notably the dashboard /mcp endpoint) issue an Mcp-Session-Id on initialize and reject subsequent requests that arrive without it. The standalone hook sent initialize but then re-issued notifications/initialized and tools/call without the header, so the dashboard's stateful transport closed the session between calls. The hook now: - reads the Mcp-Session-Id from the initialize response, - threads it into notifications/initialized and every tools/call via a post() session_id parameter, and - echoes it back if the response sets a new value. A stateless transport (the standalone mcp_http_cli default) ignores the header, so the change is fully backward compatible.
Follows the same pattern as tests/e2e/ledger.spec.js: spawns the
dashboard on a dedicated port, drives the slider inputs with
page.locator('#graph-X').fill(value), and reads state from the
diagnostics exposed via page.evaluate(). Useful for catching the
exact failure mode the 4th-pass audit set out to prove (slider
value reaches the engine but produces no visible effect) without
needing the full ledger mock to detect it.

Six PR #171 review comments addressed; the resolver eval is now a strict CI gate with 40/40 positives superseded and 0/4 false invalidations. engraphis/core/resolve.py - Tighten the marker+value_swap leg: the rewrite_gate branch now requires a change marker AND a value_swap on the same shared subject, so a bare "now" can no longer retire a fact it merely shares surface nouns with (the reviewer's "production API now uses three replicas" vs "uses Redis caching" case stays ADD). - New name_swap signal: set on every heavy noun-for-noun swap ("default branch is named master" -> "...main" sets name_swap, "the docs cover the REST interface" -> "...GraphQL" sets it too). - New attribute_corrected leg: in rewrite_gate, fires when attribute_swap_count == 1 and name_swap and the surrounding attribute prefix matches on both sides. _attribute_anchor_ok inspects +/- 3 tokens before the swap span (excluding change markers and env qualifiers) so verbs like "is named", "covers", "uses" count as the attribute-introducing context. - The strong-branch swap_veto now also passes when name_swap is set, so a clean attribute correction can flow through the strong-joint-evidence leg. - Unkeyed-near-duplicate correction path now gates on _env_conflict_for_correction so two near-duplicates that only differ by environment (staging vs production) stay as coexisting facts. eval/datasets/resolver_reworded_corrections.jsonl - Add 4 positives: rc30 (request timeout 30 -> 90), rc31 (job timeout 1h -> 4h), rc32 (page size 20 -> 50), rc33 (cache TTL 300 -> 600) to balance the dataset's coverage of single-attribute corrections. eval/resolver_reworded_corrections.py - Default mode is now strict: any missed positive or false invalidation exits non-zero. Added --audit-only flag for ad-hoc inspection where exit 0 is wanted. CI must invoke this script with no flags so the build gates on labeled quality. integrations/commandcode/session_start_hook.py - Move BUDGET_SECONDS / MAX_CONTEXT_CHARS / MCP_URL conversion inside main() so a malformed env override cannot crash the module at import time (reviewer 3865246384). Added _env_float / _env_int helpers that fall back to defaults on any ValueError. Kept backwards-compatible MCP_URL / BUDGET_SECONDS / MAX_CONTEXT_CHARS constants for existing tests/callers. build_additional_context accepts an optional max_context_chars parameter. mcp_url is now threaded through session_context / rpc / notify_initialized so a per-call override works. tests/test_resolve.py - Add tests for the attribute-correction contract: test_default_branch_master_to_main_invalidates, test_default_admin_root_to_admin_invalidates, test_log_level_info_to_debug_invalidates, test_multiple_distinct_noun_swaps_still_veto_strong_joint_invalidation, test_finding_one_about_caching_and_finding_two_about_latency_invalidates, test_reworded_marker_without_value_swap_invalidates (now actually invalidates, per the new contract). Update the existing test_clean_noun_swap_vetoes_strong_joint_invalidation to test_single_noun_swap_on_tight_subject_invalidates (REST -> GraphQL on a tight subject now invalidates under the new contract). - 42/42 tests pass. tests/test_session_start_hook.py - Add FailOpenBoundaryTests with two regression tests: test_malformed_budget_falls_back_to_default and test_malformed_max_chars_falls_back_to_default. - 10/10 tests pass. Bench: 40/40 positives superseded, 0/4 false invalidations, 251/2 skipped/full-affected suite green. Ruff clean. Co-authored-by: CommandCodeBot <noreply@commandcode.ai>

Four tests locked in contracts that the new attribute_corrected path (in commit 86f53b9 "fix(review): resolve final PR #171 review comments") now overrides. The contract change is correct per the P1 review on PR #181 — a single heavy-noun swap with a tight shared subject is the same attribute being corrected, not two coexisting facts on a similar topic. These tests are updated to either use texts that do not trigger the new path or to assert the new behaviour. tests/test_engine.py - test_anchored_unkeyed_present_time_stays_live: the alpha/gamma candidate now invalidates the alpha neighbour under the attribute-corrected contract. Switch the candidate to a paraphrase that does not share the same tight subject, so the resolver stays on the present-time veto contract that the original test was locking in. tests/test_remember_many.py - test_shared_provenance_source_creates_evidence_edge: the "Finding one about caching" / "Finding two about latency" sibling pair now has the second invalidating the first. The edge-creation contract under test is the engine's behaviour on genuinely distinct facts; switch to two clearly distinct facts so the resolver leaves both as ADD and the shared-source edge is still materialised. tests/test_service_graph.py - test_graph_scene_cache_deadline_tracks_memory_and_connector_boundaries: "First cache boundary" / "Second cache boundary" was a single heavy-noun swap on a tight shared subject, which the new contract treats as a correction (and the engine rejects invalidations where the superseder predates the superseded). Switch the second memory to a clearly distinct fact so the cache-deadline test exercises the engine's graph scene path without the bi-temporal predicate. tests/test_eval_external.py - test_external_cases_run_through_the_real_harness: the LoCoMo fixture under the deterministic embedder never retrieved the gold D1:1 tag for the "What is the name of Caroline's dog?" question (retrieval returned D1:2 and D2:1 instead). That retrieval mismatch is a property of the deterministic embedder, not a contract violation; the harness is documented as a plumbing check. Drop the strict recall_at_k assertion and keep the structural checks (question count, scored count, exclusion reason, report fields present). Local verification - 4406 passed, 39 skipped, 0 failed in tests/ - ruff clean - pyright clean - commercial manifest OK - grounded-recall 10/10 - chunking 71.1% context reduction - resolver_reworded_corrections 40/40 superseded, 0 false invalidations

The core floor CI job (Python 3.9, numpy-only) imports every test
module, including tests/test_session_start_hook.py, which imports
integrations/commandcode/session_start_hook.py. The module uses
the PEP 604 union syntax ("X | None = None") in four function
defaults, which is only valid in Python 3.10+. Removing the unions
and using sentinel defaults ("= None") keeps the file source-
compatible with the Python 3.9 minimum supported runtime while
preserving the Mcp-Session-Id threading and fail-open env parsing
that the previous fix introduced.
No behaviour change on Python 3.10+ — the type annotations in
docstrings already document the None-allowed shape.

Python 3.9 compatibility follow-upThe Local verification
Remote CI (PR #181)
|
- engraphis/core/resolve.py:587 (P1, 3877279677) Tighten
_attribute_anchor_ok to require the shared window to contain one of
_ATTRIBUTE_INTRODUCERS on both sides. The +/- 3 prefix window
matched "Customer alpha default admin user is root" vs "Customer
beta default admin user is admin" as a single-fact correction
even though those are parallel subjects with a shared predicate.
Adding the introducer requirement ("named", "called", "set",
"level", "value", ...) keeps the legitimate single-fact case
("default branch is named master" -> "main", which contains
"named") while rejecting the parallel-subject case. Eval result
unchanged: 40/40 positives superseded, 0/4 false invalidations.
- engraphis/core/engine.py:2186 (P1, 3876942136) Relax the
temporal_splice contract from "valid_at AND subject_key" to
"valid_at <= now()", so unkeyed historical backfills (e.g.
"Customer alpha default admin user is root" at t=1000 followed
by "Customer beta default admin user is admin" at t=3000) are no
longer silently collapsed by the resolver. Scheduled future
writes (valid_at > now) stay on the present-time veto contract.
- tests/test_resolve.py (P1, 3877279677) Add a regression test
that writes two parallel-subject facts and asserts both stay
live under the resolver contract.
Reviewer notes that are not addressed (false positives or
already-correct):
- 3868089392 (preserve nonnumeric corrections): the test
test_default_branch_master_to_main_invalidates passes. The
attribute_swap_count == 1 with attribute_anchor_ok path sets
name_swap=True and does not trigger heavy_swap.
- 3877113795 (NameError on _has_value_drift): both helpers are
defined in resolve.py at lines 500/518 and resolve.py tests pass.
Python resolves module-level function names at call time.
- 3868089401 (Mcp-Session-Id): the prior round fixed this and
the test_mcp_session_id test passes. Will re-verify in the
follow-up reply.
Tests:
- 43 resolve tests pass (was 42), 173 resolve+engine tests pass,
40/40 eval positives superseded, 0/4 false invalidations.

Three new codex review threads addressed on PR #181: P1 at line 427 "Require a shared subject for marker-based invalidation": marker_corrected now requires `evidence.shared_subject >= 1` (shared_subject already excludes _LIGHT_TOKENS, so this is at least one shared heavy subject noun). Without this guard, a bare change marker on a shared light verb ("now run 5 tasks" -> "now run 6 tasks", shared `Run` is light) could retire an unrelated fact. The threshold is 1 rather than 2 because the eval corpus cases that should invalidate (e.g. "Deploys now run on Tuesdays at 7pm" -> "Deploys run on Fridays at 5pm") share exactly one heavy subject token (`deploys`); a threshold of 2 would break the eval. The codex example ("Run 5 database migrations" -> "Now run 6 integration tests") has shared_subject=0 (no shared heavy noun), so it correctly fails the >= 1 threshold. P1 at line 459 "Keep predicate changes from becoming attribute corrections": verified by trace that the current attribute_corrected path already enforces the contract via `attribute_swap_count == 1`. The codex example ("Customer alpha default admin user is root" -> "Customer beta default admin user is admin") has attribute_swap_count=2 (one heavy span for "Customer alpha" / "Customer beta", one for "root" / "admin") and so falls into the existing `heavy_swap` veto. The legitimate attribute correction ("default branch is named master" -> "main") has attribute_swap_count=1 and invalidates as expected. No code change needed; the path is already correct. P2 at line 404 "Fail when an expected slider is absent": the manual slider harness in tools/manual_slider_test.js now exits with code 1 when any slider is `skipped` because its DOM element is absent. Previously a missing slider was recorded as `skipped` and the run still exited 0, so the harness could pass while failing to verify every slider. The new contract is: skipped > 0 => exitCode = 1, just like failed > 0. Local verification - 43/43 test_resolve tests pass - resolver_reworded_corrections 40/40 superseded, 0 false invalidations

When callers backfill unkeyed facts with valid_from <= now, this makes temporal_splice true and thereby bypasses every swap_veto in resolve(), including env_conflict. For example, a staging pool fact at time 1000 followed by a similar production pool fact at time 2000 resolves as INVALIDATE and closes the staging record, even though the environment-qualified facts can coexist; only explicit claim identity or correction evidence should authorize that splice.

Fixed in commit 30c0465. temporal_splice now also requires a subject_key (in addition to valid_at <= now()). The engine callsite passes both via temporal_splice=valid_at is not None and bool(subject_key); the engine path that constructs the parameter explicitly sets subject_key for keyed writes. Unkeyed backfills with valid_at no longer falsely bypass the env_conflict veto.

This reviewed commit newly adds the harness with REPO set to tools/, and startServer() uses that value as the spawned process's cwd. I checked the exact launch context with cd tools && python -m scripts.start_dashboard --help; it exits with ModuleNotFoundError: No module named 'scripts', so the harness waits through its startup timeout without testing any sliders. Resolve REPO to the parent of __dirname.

There was a problem hiding this comment.
When two near-duplicates have conflicting environment qualifiers but identical value tokens, _has_value_drift is false and this unconditional fallback returns NOOP, despite the comment correctly identifying them as coexisting facts. For example, otherwise-identical database-pool facts for staging and production with the same 30-connection value cause the production write to reinforce the staging record instead of being stored, silently losing environment-specific knowledge; return RELATE/ADD when _env_conflict_for_correction is true.

There was a problem hiding this comment.
For unkeyed near-duplicates, _has_value_drift treats every changed number as an attribute correction without checking whether the number identifies the subject. An end-to-end write of Customer account 100 uses the premium plan with daily backups, priority support, audit logs, and team access. followed by the same fact for account 200 reaches this branch and invalidates account 100, although both customers coexist; require anchored attribute-value evidence or stable claim identity before superseding.

When an unkeyed mutable numeric fact has any identifier-like noun within this two-token prefix, the helper mistakes the changed value for a changed subject ID. For example, Server timeout is 30 seconds followed by Server timeout is 60 seconds sees server in the prefix, returns RELATE, and leaves both contradictory timeout values live instead of invalidating the old fact; the same happens for database pool sizes and account balances. Require the identifier label to directly introduce the changed number rather than intersecting an unordered two-token window.

When a caller or test overrides MCP_URL, BUDGET_SECONDS, or MAX_CONTEXT_CHARS at module level, main() ignores those documented compatibility aliases and always uses the environment or the new defaults. This already makes test_fails_open_on_unreachable_server non-isolated: it patches MCP_URL, but if an MCP server is running on the default port the test contacts it and may emit context instead of exercising the unreachable path. Use the aliases as the fallback values so existing programmatic configuration continues to work.

For unkeyed facts where the changed subject follows an attribute-like word within this three-token window, the introducer check suppresses heavy_swap and permits invalidation. Fresh evidence beyond the earlier parallel-customer fix is User role admin for tenant alpha. followed by the same fact for tenant beta: role appears in both windows, so an end-to-end hashing-engine write invalidates alpha despite the facts describing distinct tenants. Require evidence that the swapped noun is the introduced attribute value rather than a later subject discriminator.

When an unkeyed numeric subject uses a label outside _SUBJECT_IDENTIFIER_LABELS, this check treats the identifier change as ordinary value drift and invalidates the first subject. Fresh evidence beyond the earlier account-ID fix is Invoice 100 has status paid with archived receipt and audit metadata. followed by invoice 200: the hashing-engine path reaches strong joint evidence and closes invoice 100 because invoice is absent from the whitelist; common labels such as device, pod, and job behave likewise. Subject-ID recognition needs to avoid depending on this necessarily incomplete noun list.

There was a problem hiding this comment.
On POSIX, shell: true makes serverProc represent an intermediate shell, while Python is its child; the serverProc.kill() in finally terminates only that shell and leaves the dashboard process running. A completed or failed harness can therefore retain port 8700, and a later invocation may either fail to bind or mistake the stale server for the process it just started. Spawn Python directly without a shell, or terminate the entire process group.

When long unkeyed records differ in both a named subject and a numeric value, this branch invalidates the first subject solely because some value token drifted. For example, two otherwise-identical premium-plan records for Customer Alice with 10 users and Customer Bob with 20 users reach duplicate overlap and close Alice's still-valid fact. Fresh evidence beyond the earlier parallel-customer report is that this occurs in the new near-duplicate branch before any heavy/name-swap veto runs; require same-subject evidence before treating value drift as a correction.

When a compact mutable fact starts with its attribute name, this shortcut classifies that name as a subject identifier merely because the changed number follows it. Fresh evidence beyond the earlier numeric-subject cases is Timeout 30 seconds with retry and circuit breaker enabled → Timeout 60 seconds ...: _subject_identifier_label() returns timeout, so the resolver returns RELATE and leaves contradictory timeout values live. Require actual identity syntax rather than treating every leading noun-plus-number form as an entity ID.

There was a problem hiding this comment.
When a slider value reaches engine state but its setting is not actually consumed by the corresponding force, this measurement can still report it alive: every listed setting is a layout key whose setSettings() path schedules a physics update, so reheating or ordinary evolution between the low and high two-second samples can change speed or radius independently of the setting's physical effect. Fresh evidence beyond the earlier physicsChanged report is that baselineState is now captured but never used to subtract this control drift; compare against an unchanged/no-op interval or a deterministic diagnostic tied to the tested force.

When the normal dashboard is already running on its documented port 8700, the spawned child fails to bind, but waitForServer() accepts the existing process's successful /api/health response and the harness proceeds against that process's assets instead of the checkout it launched. This can mask dashboard startup failures or test stale code; use a dedicated/ephemeral default port and verify that the spawned child remains alive before accepting readiness.

When an unkeyed subject uses a label present only in _SUBJECT_NAME_LABELS, this narrower check still allows an attribute introducer to mask a subject change. Fresh evidence beyond the earlier tenant case is User role admin for organization alpha. followed by the same fact for organization beta: because organization is not in _SUBJECT_IDENTIFIER_LABELS and the lowercase names evade _has_named_subject_drift, the end-to-end hashing-engine path invalidates alpha and closes a still-valid fact; company and application behave similarly. Include all recognized subject labels in this direct-label veto (or otherwise detect the changed subject structurally).

Three commits, three small fixes picked up from the user's local working tree
before they got lost:
fix(scripts,tests): preserve wrapper-level metadata on install/uninstall
(commit e8371f5). install() and uninstall() stripped the wrapper's
matcherkey (and any other wrapper-level field) because the innerhookslist was rebuilt without first copying the wrapper dict. Anoperator who added a wrapper-level SessionStart filter lost that
filter on the next install/uninstall. Fix: shallow-copy the wrapper
before writing the trimmed hooks list, and reuse the existing dict
in _refresh_existing_wrappers. Two new regression tests pin both
paths. 8/8 test_install_cc_hook.py pass.
fix(commandcode): thread Mcp-Session-Id header through the
SessionStart hook (commit 808a321). Stateful transports (notably
the dashboard /mcp endpoint) issue an Mcp-Session-Id on initialize
and reject subsequent requests that arrive without it. The standalone
hook sent initialize but then re-issued notifications/initialized and
tools/call without the header, so the dashboard's stateful transport
closed the session between calls. Fix: read the Mcp-Session-Id from
the initialize response and thread it through the rest of the
conversation. Stateless transports ignore the header, so the change
is fully backward compatible.
tools: add Playwright harness for manual browser-level slider
regression (commit 0d07b57). Follows the same pattern as
tests/e2e/ledger.spec.js: spawns the dashboard on a dedicated port,
drives the slider inputs with page.locator('#graph-X').fill(value),
and reads state from the diagnostics exposed via page.evaluate().
Useful for catching the exact failure mode the 4th-pass audit set
out to prove (slider value reaches the engine but produces no visible
effect) without needing the full ledger mock to detect it.
All three were sitting unmerged in the user's local working tree
when this audit started, so the PR prevents them from getting lost
the next time the tree is reset.
