 ## Status
 
-Scaffolding in place. Implementation, PRD, tests, and CI are coming next per plan.
+Release branch open for v0.4.0-alpha: see PR https://github.com/flyingrobots/go-redis-work-queue/pull/1

+# Promotion Checklists
+
+- Last updated: 2025-09-12
+
+## Alpha → Beta Checklist
+- [ ] Functional completeness: producer, worker, all-in-one, reaper, breaker, admin CLI
+- [ ] Observability: /metrics, /healthz, /readyz live and correct
+- [ ] CI green on main (build, vet, race, unit, integration, e2e)
+- [ ] Unit coverage ≥ 80% core packages (attach coverage report)
+- [ ] E2E passes deterministically (≥ 5 runs)
+- [ ] govulncheck: no Critical/High in code paths/stdlib
+- [ ] Performance baseline: 1k jobs at 500/s complete; limiter ±10%/60s
+- [ ] Docs: README, PRD, test plan, deployment, runbook updated
+- Evidence links:
+  - CI run URL: …
+  - Bench JSON: …
+  - Metrics snapshot(s): …
+  - Issues list: …
+
+### Confidence Scores (Alpha → Beta)
+
+| Criterion | Confidence | Rationale | How to improve |
+|---|---:|---|---|
+| Functional completeness | 0.9 | All core roles implemented and tested; admin CLI present | Add more end-to-end tests for admin flows; document edge cases |
+| Observability endpoints | 0.95 | Live and exercised in CI/e2e; stable | Add /healthz readiness probes to example manifests; alert rules examples |
+| CI health | 0.9 | CI green with race, vet, e2e, govulncheck | Increase matrix (Go versions, OS); add flaky-test detection |
+| Coverage ≥ 80% | 0.75 | Core packages covered; gaps in admin/obs | Add tests for admin and HTTP server handlers |
+| E2E determinism | 0.8 | E2E with Redis service stable locally and in CI | Add retries and timing buffers; run 5x in workflow and gate |
+| Security (govulncheck) | 0.95 | Using Go 1.24; no critical findings | Add image scanning; pin base image digest |
+| Performance baseline | 0.7 | Bench harness exists; sample run meets ~960 jobs/min, latency sampling coarse | Improve latency measurement via metrics; run on 4 vCPU node and document env |
+| Documentation completeness | 0.9 | PRD, runbook, deployment, perf, checklists present | Add Helm usage examples and alert rules |
+
+## Beta → RC Checklist
+- [ ] Throughput ≥ 1k jobs/min for ≥ 10m; p95 < 2s (<1MB files)
+- [ ] Chaos tests: Redis outage/latency/worker crash → no lost jobs; breaker transitions
+- [ ] Admin CLI validated against live instance
+- [ ] Queue gauges and breaker metric accurate under load
+- [ ] 24–48h soak: error rate < 0.5%, no leaks
+- [ ] govulncheck clean; deps pinned
+- [ ] Docs: performance report and tuning
+- [ ] No P0/P1; ≤ 3 P2s w/ workarounds
+- Evidence links as above
+
+## RC → GA Checklist
+- [ ] Code freeze; only showstopper fixes
+- [ ] 0 P0/P1; ≤ 2 P2s with workarounds; no flakey tests across 10 runs
+- [ ] Release workflow proven; rollback rehearsal complete
+- [ ] Config/backcompat validated or migration guide
+- [ ] Docs complete; README examples validated
+- [ ] govulncheck clean; image scan no Critical
+- [ ] 7-day RC soak: readiness > 99.9%, DLQ < 0.5%
+- Evidence links as above
+### Confidence Scores (Beta → RC)
+
+| Criterion | Confidence | Rationale | How to improve |
+|---|---:|---|---|
+| ≥1k jobs/min for ≥10m | 0.6 | Not yet run on dedicated 4 vCPU node | Schedule controlled benchmark; record metrics and environment |
+| p95 < 2s (<1MB) | 0.6 | Latency sampling method is coarse | Use Prometheus histogram quantiles on /metrics; run sustained test |
+| Chaos (outage/latency/crash) | 0.7 | Logic supports recovery; tests cover happy-path and reaper | Add chaos e2e in CI (stop Redis container; tc latency); verify no loss |
+| Admin validation | 0.85 | Admin commands tested manually; unit tests for helpers | Add e2e assertions for stats and peek outputs |
+| Gauges/breaker accuracy | 0.85 | Metrics wired; observed locally | Add metric assertions in e2e; dashboards and alerts validate |
+| 24–48h soak | 0.5 | Not yet executed | Run soak in staging and record dashboards |
+| Security and deps | 0.9 | govulncheck in CI; deps pinned | Add Renovate/Dependabot; image scanning stage |
+| Issue hygiene | 0.9 | No open P0/P1 | Enforce labels and triage automation |
+### Confidence Scores (RC → GA)
+
+| Criterion | Confidence | Rationale | How to improve |
+|---|---:|---|---|
+| Code freeze discipline | 0.8 | Process defined; branch protection enabled | Require 1 review and passing checks (enabled); add CODEOWNERS |
+| Zero P0/P1; ≤2 P2 | 0.85 | Current backlog clean | Maintain triage; add SLOs for bug classes |
+| Release workflow | 0.9 | GoReleaser + GHCR configured; test via pre-release | Dry-run snapshot and tag a pre-release on branch |
+| Rollback rehearsal | 0.6 | Procedure documented | Execute runbook in staging and document proof |
+| Backward compatibility | 0.8 | Config stable; validation added | Add versioned config schema and migration notes |
+| Docs completeness | 0.9 | Extensive docs present | Add Grafana/Prometheus import snippets and examples (added dashboard) |
+| 7-day soak | 0.5 | Not yet executed | Run RC soak with dashboard snapshots and attach to evidence |

+# Evidence for v0.4.0-alpha Promotion
+
+- CI run: see `ci_run.json` (contains URL to the successful workflow run)
+- Bench JSON: `bench.json` (admin bench with 1000 jobs at 500 rps)
+- Config used: `config.alpha.yaml`
+- Metrics snapshots: `metrics_before.txt`, `metrics_after.txt`
+
+Reproduce locally
+
+1) Ensure Redis is running on `localhost:6379` (e.g., `docker run -p 6379:6379 redis:7-alpine`)
+2) Build binary: `make build`
+3) Start worker: `./bin/job-queue-system --role=worker --config=docs/evidence/config.alpha.yaml`
+4) In another terminal, run bench: `./bin/job-queue-system --role=admin --config=docs/evidence/config.alpha.yaml --admin-cmd=bench --bench-count=1000 --bench-rate=500 --bench-priority=low --bench-timeout=60s`
+5) Capture metrics: `curl -sS localhost:9191/metrics | head -n 200 > docs/evidence/metrics_after.txt`
+
+Notes
+- The simple latency reported in `bench.json` is measured by comparing current time to each job's creation_time after completion sampling and is a coarse approximation. For precise latency distributions, prefer Prometheus histogram `job_processing_duration_seconds` and compute quantiles there.
