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.

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.

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.
