--- id: 3806 title: Review Dispositions Ledger group: Planning Features --- **Purpose:** Reviews-mode planning (`/gsd-plan-phase {N} --reviews`) has required every current actionable REVIEWS.md finding to be incorporated into PLAN.md or explicitly deferred/rejected there since v1.5.0 (#724/#728). Nothing canonized *where* in PLAN.md, *what shape*, or how a REVIEWS.md line reference survives the next round rewriting the file wholesale. Two independently-invented, mutually incompatible disposition formats were observed across two consecutive rounds of the same phase, each written by a different planner subagent instance improvising from prose alone. **Behavior:** The existing return-payload tables from `references/planner-reviews.md` Step 4 — `### Review Feedback Addressed` / `### Review Feedback Deferred` — are now the canonical **Review Dispositions Ledger**, promoted verbatim in shape into the affected PLAN.md itself under a `## Review Dispositions Ledger` heading. Each reviews-mode round gets its own `### Round {N} — {REVIEWS_sha}` subsection, where `{REVIEWS_sha}` is the commit that wrote that round's REVIEWS.md snapshot (`workflows/review.md` already commits REVIEWS.md as its own commit). A REVIEWS.md line reference cites `L##@{REVIEWS_sha}`; a bare line number is non-conforming. The ledger is append-only — a later round adds a new row naming what it supersedes rather than editing or deleting an earlier round's tables. The contract is stated once, in `references/planner-reviews.md`; `workflows/plan-phase.md`'s `` and `agents/gsd-plan-checker.md`'s Review Incorporation dimension both reference it by name rather than restating it, guarded by a parity test (`tests/plan-review-convergence.test.cjs`) that fails if the three drift apart. `{Concern}`/`{Reason}` stay free text — the reviewer roster is capability-owned and open to third-party additions, so no closed reviewer/severity enum is introduced. **Known limits:** No lint or check verb enforces this shape yet — a follow-up (tracked as part 2 of #3806) will add deterministic enforcement once a migration story for the two pre-existing ad-hoc formats already in the wild is decided. Legacy PLAN.md content written before this convention is not migrated or flagged. **Reference:** [ADR-3806](adr/3806-review-dispositions-ledger.md) · [Cross-AI Peer Review](#42-cross-ai-peer-review)
