MINOR - two batches + close-out wording.
- Added - transcript-GC recovery honesty: the journal records the session's transcript path; the resume block flags a garbage-collected transcript (claude --resume is dead for this session) and, when CoalWash is installed, routes deeper recovery to its read-only estate-search/estate-restore (degrade-safe absent). CC transcript retention is version-dependent, not a guaranteed 30 days - field-confirmed.
- Fixed - Antigravity adapters re-derived to the current PreInvocation contract: workspacePaths[0]/conversationId first, emit = injectSteps/ephemeralMessage; the pilot-era additionalContext key retired (dead letter). Tier stays wired (hermetically tested; live AG delivery not yet validated).
- Fixed - descriptions: plugin/marketplace wording corrected budget-guardrail -> handover-journal (the guardrail was removed at v2.0.0).
Gate: 133/133 hermetic tests, VERIFY PASS. Full detail: CHANGELOG.
