 # ArcheFlow — Status Log
 
+## 2026-04-04: Triple Release Sprint (v0.4 → v0.6)
+
+### What happened
+Three ArcheFlow PDCA cycles in one session, each using ArcheFlow's own orchestration to develop itself (dogfooding). Each cycle: Explorer→Creator→Maker→Guardian+Skeptic+Sage→fixes→merge→push.
+
+### v0.4.0 — Gap Fixes (8 commits, 541 lines, 15 files)
+- Unified feedback routing tables across 3 skills (canonical 8-row version)
+- Confidence gate with concrete bash parsing, 3 branches (pause/upgrade/mini-Explorer)
+- `archeflow-rollback.sh` — post-merge auto-revert with `--mainline 1`
+- Test-first validation gate in Do phase (word-boundary patterns)
+- Memory injection audit trail (`--audit` flag, `audit-check` command)
+- Review fixes: safe jq `--arg`, confidence fallback→0.0, pattern hardening
+
+### v0.5.0 — Infrastructure (8 commits, 483 lines, 12 files)
+- Lib script validation at run initialization (0a)
+- Hook points documentation (`docs/hooks.md` + config template with 6 events)
+- Phase rollback via `--to <phase>` in rollback script
+- Per-workflow model assignment configuration
+- Cross-run finding regression detection
+- Check-phase fleshed out with parallel reviewer spawning protocol
+- Review fixes: mutual exclusivity guard, jq --arg everywhere, table-row grep
+
+### v0.6.0 — Quality Polish (5 commits, 253 lines, 13 files)
+- Attention-filters expanded from 39-line stub to full skill (prompt templates, token budgets, cycle-back rules, verification checklist)
+- Explorer skip heuristic in plan-phase skill
+- Agent persona normalization (4 agents: examples, model comments, isolation note)
+- Runnable quickstart example (`examples/runnable-quickstart.md`)
+- CHANGELOG completed with missing v0.4.0 entry + roadmap version history
+
+### Key numbers
+| Metric | v0.3 → v0.6 delta |
+|--------|-------------------|
+| Commits this session | 21 |
+| Lines added | ~1,277 |
+| Files touched | 25+ |
+| Lib scripts | 8 → 9 (archeflow-rollback.sh) |
+| Skills | 24 (all now fleshed out) |
+| Review cycles | 3 (Guardian + Skeptic + Sage per round) |
+| Review findings fixed | 11 |
+
+### What to do next
+1. **End-to-end dogfood** — run `af-run` on a real task (not ArcheFlow itself) to test the full PDCA loop
+2. **Hook execution runtime** — the config documents 6 hook events but no runner yet
+3. **Publish** — consider tagging v0.6.0 and announcing on git.xorwell.de
+4. **GitHub Action** — automated PR review (roadmap item, low effort)
