kata-plan-milestone-gaps（卡塔计划里程碑差距）

Reads MILESTONE-AUDIT.md, groups gaps into logical phases, creates phase entries in ROADMAP.md, and offers to plan each phase.

One command creates all fix phases — no manual /kata-add-phase per gap.

<execution_context>

</execution_context>

Original intent (for prioritization): @.planning/PROJECT.md @.planning/REQUIREMENTS.md

Current state: @.planning/ROADMAP.md @.planning/STATE.md

0. Pre-flight: Check roadmap format (auto-migration)

If ROADMAP.md exists, check format and auto-migrate if old:

if [ -f .planning/ROADMAP.md ]; then
  node scripts/kata-lib.cjs check-roadmap 2>/dev/null
  FORMAT_EXIT=$?

  if [ $FORMAT_EXIT -eq 1 ]; then
    echo "Old roadmap format detected. Running auto-migration..."
  fi
fi

If exit code 1 (old format):

Invoke kata-doctor in auto mode:

Skill("kata-doctor", "--auto")

Continue after migration completes.

If exit code 0 or 2: Continue silently.

1. Load Audit Results

# Find the most recent audit file
find .planning -maxdepth 1 -name "v*-MILESTONE-AUDIT.md" 2>/dev/null | head -1

Parse YAML frontmatter to extract structured gaps:

• gaps.requirements — unsatisfied requirements
• gaps.integration — missing cross-phase connections
• gaps.flows — broken E2E flows

If no audit file exists or has no gaps, error:

No audit gaps found. Run `/kata-audit-milestone` first.

2. Prioritize Gaps

Group gaps by priority from REQUIREMENTS.md:

For integration/flow gaps, infer priority from affected requirements.

3. Group Gaps into Phases

Cluster related gaps into logical phases:

Grouping rules:

• Same affected phase → combine into one fix phase
• Same subsystem (auth, API, UI) → combine
• Dependency order (fix stubs before wiring)
• Keep phases focused: 2-4 tasks each

Example grouping:

Gap: DASH-01 unsatisfied (Dashboard doesn't fetch)
Gap: Integration Phase 1→3 (Auth not passed to API calls)
Gap: Flow "View dashboard" broken at data fetch

→ Phase 6: "Wire Dashboard to API"
  - Add fetch to Dashboard.tsx
  - Include auth header in fetch
  - Handle response, update state
  - Render user data

4. Determine Phase Numbers

Find highest existing phase:

# Scan all phase directories across states
ALL_PHASE_DIRS=""
for state in active pending completed; do
  [ -d ".planning/phases/${state}" ] && ALL_PHASE_DIRS="${ALL_PHASE_DIRS} $(find .planning/phases/${state} -maxdepth 1 -type d -not -name "${state}" 2>/dev/null)"
done
# Fallback: include flat directories (backward compatibility)
FLAT_DIRS=$(find .planning/phases -maxdepth 1 -type d -name "[0-9]*" 2>/dev/null)
[ -n "$FLAT_DIRS" ] && ALL_PHASE_DIRS="${ALL_PHASE_DIRS} ${FLAT_DIRS}"
echo "$ALL_PHASE_DIRS" | tr ' ' '\n' | sort -V | tail -1

New phases continue from there:

• If Phase 5 is highest, gaps become Phase 6, 7, 8...

5. Present Gap Closure Plan

## Gap Closure Plan

**Milestone:** {version}
**Gaps to close:** {N} requirements, {M} integration, {K} flows

### Proposed Phases

**Phase {N}: {Name}**
Closes:
- {REQ-ID}: {description}
- Integration: {from} → {to}
Tasks: {count}

**Phase {N+1}: {Name}**
Closes:
- {REQ-ID}: {description}
- Flow: {flow name}
Tasks: {count}

{If nice-to-have gaps exist:}

### Deferred (nice-to-have)

These gaps are optional. Include them?
- {gap description}
- {gap description}

---

Create these {X} phases? (yes / adjust / defer all optional)

Wait for user confirmation.

6. Update ROADMAP.md

Add new phases to current milestone:

### Phase {N}: {Name}
**Goal:** {derived from gaps being closed}
**Requirements:** {REQ-IDs being satisfied}
**Gap Closure:** Closes gaps from audit

### Phase {N+1}: {Name}
...

7. Create Phase Directories

# New gap closure phases go into pending/ subdirectory
mkdir -p ".planning/phases/pending/{NN}-{name}"

8. Commit Roadmap Update

Check planning config:

COMMIT_PLANNING_DOCS=$(node scripts/kata-lib.cjs read-config "commit_docs" "true")
git check-ignore -q .planning 2>/dev/null && COMMIT_PLANNING_DOCS=false

If COMMIT_PLANNING_DOCS=false: Skip git operations

If COMMIT_PLANNING_DOCS=true (default):

git add .planning/ROADMAP.md
git commit -m "docs(roadmap): add gap closure phases {N}-{M}"

9. Offer Next Steps

## ✓ Gap Closure Phases Created

**Phases added:** {N} - {M}
**Gaps addressed:** {count} requirements, {count} integration, {count} flows

---

## ▶ Next Up

**Plan first gap closure phase**

`/kata-plan-phase {N}`

<sub>`/clear` first → fresh context window</sub>

---

**Also available:**
- `/kata-execute-phase {N}` — if plans already exist
- `cat .planning/ROADMAP.md` — see updated roadmap

---

**After all gap phases complete:**

`/kata-audit-milestone` — re-audit to verify gaps closed
`/kata-complete-milestone {version}` — archive when audit passes

How Gaps Become Tasks

Requirement gap → Tasks:

gap:
  id: DASH-01
  description: "User sees their data"
  reason: "Dashboard exists but doesn't fetch from API"
  missing:
    - "useEffect with fetch to /api/user/data"
    - "State for user data"
    - "Render user data in JSX"

becomes:

phase: "Wire Dashboard Data"
tasks:
  - name: "Add data fetching"
    files: [src/components/Dashboard.tsx]
    action: "Add useEffect that fetches /api/user/data on mount"

  - name: "Add state management"
    files: [src/components/Dashboard.tsx]
    action: "Add useState for userData, loading, error states"

  - name: "Render user data"
    files: [src/components/Dashboard.tsx]
    action: "Replace placeholder with userData.map rendering"

Integration gap → Tasks:

gap:
  from_phase: 1
  to_phase: 3
  connection: "Auth token → API calls"
  reason: "Dashboard API calls don't include auth header"
  missing:
    - "Auth header in fetch calls"
    - "Token refresh on 401"

becomes:

phase: "Add Auth to Dashboard API Calls"
tasks:
  - name: "Add auth header to fetches"
    files: [src/components/Dashboard.tsx, src/lib/api.ts]
    action: "Include Authorization header with token in all API calls"

  - name: "Handle 401 responses"
    files: [src/lib/api.ts]
    action: "Add interceptor to refresh token or redirect to login on 401"

Flow gap → Tasks:

gap:
  name: "User views dashboard after login"
  broken_at: "Dashboard data load"
  reason: "No fetch call"
  missing:
    - "Fetch user data on mount"
    - "Display loading state"
    - "Render user data"

becomes:

# Usually same phase as requirement/integration gap
# Flow gaps often overlap with other gap types
