v1.2.9

Changed

• Stop nudge now recommends the one-command close-out /mn:review --full instead of listing /mn:save and /mn:session separately — aligning the automatic end-of-session reminder with the v1.2.8 one-command close-out (Codex: $mnemo:review --full). The gating is unchanged: opt-in hooks.stopNudge, worth-saving signals ≥3, save/session not yet run, blocks at most once per session.

Fixed

• Stop nudge over-firing in Codex — the anti-loop governor keyed only on the Stop payload's session_id, which a Codex Stop payload can omit or vary, so the once-per-session marker failed to dedup and the nudge could fire on every Stop. It now falls back to CODEX_THREAD_ID / CODEX_SESSION_ID for a stable per-thread key. New scripts/test-stop-nudge.py (7 cases) pins the --full recommendation, both runtimes' syntax, once-per-session dedup, the Codex thread-key fallback, and the silence conditions (below-threshold signals, save+session already ran, recursion guard).
