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.

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and eval/resolver_reworded_corrections.py that drives core.resolve.resolve() over the corpus and reports positives-superseded, false-invalidations, and missed-correction ids.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.

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 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.

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.

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. --- .../commandcode/session_start_hook.py | 74 ++++++++++++++----- 1 file changed, 57 insertions(+), 17 deletions(-) diff --git a/integrations/commandcode/session_start_hook.py b/integrations/commandcode/session_start_hook.py index 734686f9..f7ab3d52 100644 --- a/integrations/commandcode/session_start_hook.py +++ b/integrations/commandcode/session_start_hook.py @@ -23,9 +23,20 @@ # Localhost server; never route through a configured system proxy.

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.

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).

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. --- engraphis/core/engine.py | 17 +++++++++++------ engraphis/core/resolve.py | 33 +++++++++++++++++++++++++++++---- tests/test_resolve.py | 28 ++++++++++++++++++++++++++++ 3 files changed, 68 insertions(+), 10 deletions(-) diff --git a/engraphis/core/engine.py b/engraphis/core/engine.py index 444e8845..8c91df38 100644 --- a/engraphis/core/engine.py +++ b/engraphis/core/engine.py @@ -2175,15 +2175,20 @@ def append_visible_neighbors( for sim, rec in extra_neighbors: if rec.id not in known_ids: neighbors.append((sim, rec)) - # Bi-temporal backfill only: anchored writes (valid_at pinned AND a - # subject_key is present) assert explicit chain membership and may - # supersede a live neighbour even when prose alone would suggest two - # coexisting facts.
