# Cycle #99 Checkpoint: Bundle Status & Phase 1 Readiness (2026-04-23 08:53 Seoul)

## Active Branch Status

**Branch:** `feat/jobdori-168c-emission-routing`
**Commits:** 15 (since Phase 0 start at cycle #89)
**Tests:** 227/227 pass (cumulative green run, zero regressions)
**Axes of work:** 5

### Work Axes Breakdown

| Axis | Pinpoints | Cycles | Status |
|---|---|---|---|
| **Emission** (Phase 0) | #168c | #89-#92 | ✅ COMPLETE (4 tasks) |
| **Discoverability** | #155, #153 | #93.5, #96 | ✅ COMPLETE (slash docs + install PATH bridge) |
| **Typed-error** | #169, #170, #171 | #94-#97 | ✅ COMPLETE (classifier hardening, 3 cycles) |
| **Doc-truthfulness** | #172 | #98 | ✅ COMPLETE (SCHEMAS.md inventory lock + regression test) |
| **Deferred** | #141 | — | ⏸️ OPEN (list-sessions --help routing) |

### Cycle Velocity (Cycles #89-#99)

- **11 cycles, ~90 min total execution**
- **5 pinpoints closed** (#155, #153, #169, #170, #171, #172 — actually 6 filed, 1 deferred #141)
- **Zero regressions** (all test runs green)
- **Zero scope creep** (each cycle's target landed as designed)

### Test Coverage

- **output_format_contract.rs:** 19 tests (Phase 0 tasks + dogfood regressions)
- **All other crates:** 208 tests
- **Total:** 227/227 pass

## Branch Deliverables (Ready for Review)

### 1. Phase 0 Tasks (Emission Baseline)
- **What:** JSON output envelope is now deterministic, no-silent, cataloged, and drift-protected
- **Evidence:** 4 commits, code + test + docs + parity guard
- **Consumer impact:** Downstream claws can rely on JSON structure guarantees

### 2. Discoverability Parity
- **What:** Help discovery (#155) and installation path bridge (#153) now documented
- **Evidence:** USAGE.md expanded by 54 lines
- **Consumer impact:** New users can build from source and run `claw` without manual guessing

### 3. Typed-Error Robustness
- **What:** Classifier now covers 8 error patterns; 7 tests lock the coverage
- **Evidence:** 3 commits, 6 classifier branches, systematic regression guards
- **Consumer impact:** Error `kind` field is now reliable for dispatch logic

### 4. Doc-Truthfulness Lock
- **What:** SCHEMAS.md Phase 1 target list now matches reality (3 verbs have `action`, not 4)
- **Evidence:** 1 commit, corrected doc, 11-assertion regression test
- **Consumer impact:** Phase 1 adapters won't chase nonexistent 4th verb

## Deferred Item (#141)

**What:** `claw list-sessions --help` errors instead of showing help
**Why deferred:** Parser refactor scope (not classifier-level), deferred end of #97
**Impact:** Not on this branch; Phase 1 target? Unclear

## Readiness Assessment

### For Review
✅ **Code quality:** Steady test run (227/227), zero regressions, coherent commit messages
✅ **Scope clarity:** 5 axes clearly delimited, each with pinpoint tracking
✅ **Documentation:** SCHEMAS.md locked, ROADMAP updated per pinpoint, memory logs documented
✅ **Risk profile:** Low (mostly regression tests + doc fixes, no breaking changes)

### Not Ready For
❌ **Merge coordination:** Awaiting explicit signal from review lead
❌ **Integration:** 8 other branches in rebase queue; recommend prioritization discussion

## Recommended Next Action

1. **Push branch for review** (when review queue capacity available)
2. **Or file Phase 1 design decision** (#164 Option A vs B) if higher priority
3. **Or continue dogfood probes** on new axes (event/log opacity, MCP lifecycle, session boot)

## Doctine Reinforced This Cycle

- **Probe pivot strategy works:** Non-classifier axes (shape/discriminator, doc-truthfulness) yield 2-4 pinpoints per 10-min cycle at current coverage
- **Regression guard prevents re-drift:** SCHEMAS.md + test combo ensures doc-truthfulness sticks across future commits
- **Bundle coherence:** 5 axes across 15 commits still review-friendly because each pinpoint is clearly bounded

**Branch is stable, test suite green, and ready for review or Phase 1 work. Checkpoint filed for arc continuity.**
