 Broad G4/background consolidation apply mode remains blocked. Fresh linkage diagnostics passed, but historical scheduled-dry-run still blocks on `trace_quality_needs_more_dogfooding`, `decay_risk_above_threshold`, and `background_quality_warnings_present`. The first mutating review-queue/candidate corridors remain deliberately narrow and require explicit policy, approval phrase, actor, reason hash, backup, audit row, and rollback hint.
 
-Historical G4 contract checkpoint remains docs/RED-test-only: PR #200, PR #202, PR #204, v0.1.99 runtime `/Users/reddit/.agent-memory/runtime/v0.1.99/.venv/bin/agent-memory`, and report `/Users/reddit/.agent-memory/reports/v0.1.99-runtime-qa-20260507T074118` are retained as the broad-G4-blocked baseline. Later releases hardened only narrow cleanup/restore/audit safety corridors, blocker diagnostics, and future trace/observation quality; they did not enable broad background consolidation mutation.

-2. Keep G5d/G5e semantics narrow: review scores and recommendations are review-priority signals only; they do not persist review state, increment/decrement reinforcement, promote memories, auto-approve ordinary conversation, or change retrieval defaults.
