# Backlog reconcile ## Overview Audit a repo's git-tracked `_meta/BACKLOG.md` Active queue against reality and ship the fixes as a PR. This is the backlog-reconcile instance of `docs/patterns/audit-loop.md` (the pattern doc's own "Backlog reconcile" SDLC-instances row): every adopter repo gets this schema via `/kit:adopt`, so this instance is general-purpose, not maintainer-only like `topology-drift`. ## The four slots (per the audit-loop pattern) | Slot | This instance | |---|---| | Item set | every row of the target repo's `_meta/BACKLOG.md` Active queue, enumerated via `lib/board/backlog.sh board` (id/title/status) plus a raw read of the file for each row's `Target artifact` cell | | Contract | a row's `Status` matches reality: (a) a `shipped` row not exempted by a `_meta/megagoals/` target artifact must have already dropped off the queue; (b) a `Target artifact` naming `SPEC-NNN` must point at a real file whose own `Status:` header agrees with the board's `Status`; (c) a `(tiny, no spec)` row's `executing`/`shipped` claim must have a git-log match | | Evidence class | Tier 1: mechanical, batched (file existence, `grep -m1` header extraction, one batched `git log --grep -F` pass). Tier 2: `agents/audit-scanner.md`, dispatched only on the Tier-1 delta, chunked ~25-30 rows per call, fed any `gh` evidence this skill gathers itself | | Apply mechanics | the ONLY mutation is `bash lib/board/backlog.sh set <ID> <state> [note]` (mechanical, preserves annotation prose); best-e
