# Release Readiness Gate ## Purpose Aggregate verify status, open P0/P1 review findings, the coverage ledger, and waivers into a single `go`/`hold`/`hold-with-waiver` recommendation with per-line evidence for each input. Absorbs most of Ship's individual refusal conditions into one composite check. This is a power skill, not a lifecycle phase. It is gate-bound: it runs at every Ship Exit Gate, consuming `coverage-tracer`'s ledger and `skipped-check-accountant`'s accounting. ## Invocation Context Use this skill when: - Ship is about to set its `Ship Status` recommendation - all upstream inputs (verify sign-off, review findings, coverage ledger, waivers) are available to aggregate Do not invoke it before Test's verify artifact exists — there is no verify status to aggregate yet. ## What To Load **Foundation** (confirm in context; load if not already present): - Root `AGENTS.md` - `workflow/router.md` - `workflow/lifecycle.md` - `workflow/rules.md` **Minimum for invocation**: - This file - `references/output-schema.md` **Before starting work**: - `references/aggregation-rules.md` — how the four inputs combine into one recommendation - The verify artifact's `Sign-Off` - The review artifact's `Severity Summary` - The coverage ledger (from `coverage-tracer`) - Any waivers (checked via `waiver-completeness-check`) ## Inputs - Verify artifact's sign-off outcome (`ship`, `hold`, `hold-with-waiver`). - Review artifact's open findings by severity (P0/P1/P2/P3). - The covera
