chore(rebar): Pier_T_rebar 작업 폴더 초기 구성 및 외부 의존 파일 통합

- Code\rebar_pipeline, review_pipeline, pier-program을 정션에서 실제 폴더로 전환 - Code\rhino_mcp 및 CLAUDE_rhino배경.md 추가, .mcp.json은 PYTHONPATH로 새 위치 사용 - pier-program 내부 .git 제거(이력은 backup\pier-program_20261028.bundle에 보관) - worktree 가이드 반영(CLAUDE.local.md, HANDOFF.md) - D:\Rhino-MCP 경로 참조를 새 위치로 치환 Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

+# Audit Skill

+> User-invocable skill for viewing audit logs, decision traces, and session history.
+
+## Arguments
+
+| Argument | Description | Example |
+|----------|-------------|---------|
+| (none) | Show recent audit log entries (same as `log`) | `/audit` |
+| `log` | Show recent audit log entries (last 20) | `/audit log` |
+| `trace <feature>` | Show decision traces for a feature | `/audit trace user-auth` |
+| `summary` | Show daily/weekly audit summary | `/audit summary` |
+| `search <query>` | Search audit logs by action type, feature, or date | `/audit search "phase_transition"` |
+
+## Action Details
+
+### log (Default)
+
+Display recent audit log entries.
+
+1. Read today's audit log from `.hmcmkit/audit/YYYY-MM-DD.jsonl`
+2. If today's log is empty or has fewer than 20 entries, also read yesterday's log
+3. Parse JSONL entries (one JSON object per line)
+4. Display the last 20 entries in reverse chronological order
+5. Format each entry with timestamp, action, feature, and details
+
+**JSONL Entry Schema**:
+```json
+{
+  "timestamp": "2026-03-19T10:30:00.000Z",
+  "action": "phase_transition",
+  "feature": "user-auth",
+  "from": "plan",
+  "to": "design",
+  "automationLevel": "semi-auto",
+  "triggeredBy": "user",
+  "details": "Plan approved, transitioning to Design"
+}
+```
+
+**Output Format**:
+```
+--- Audit Log (Last 20 Entries) -------------------
+[2026-03-19 10:30] phase_transition | user-auth
+  plan -> design (Semi-Auto, user-triggered)
+
+[2026-03-19 10:25] checkpoint_created | user-auth
+  Checkpoint cp-1710842700000 before Design phase
+
+[2026-03-19 10:20] automation_level_changed | -
+  L1 -> L2 (trust score: 72)
+...
+---------------------------------------------------
+Total entries today: 45
+```
+
+### trace <feature>
+
+Show decision traces for a specific feature.
+
+1. Read decision trace files from `.hmcmkit/decisions/YYYY-MM-DD.jsonl`
+2. Filter entries matching the specified feature
+3. Display chronological decision chain with rationale
+
+**Decision Trace Entry Schema**:
+```json
+{
+  "timestamp": "2026-03-19T10:30:00.000Z",
+  "feature": "user-auth",
+  "decision": "advance_to_design",
+  "rationale": "Plan document complete, matchRate N/A at this phase",
+  "alternatives": ["request_plan_revision", "skip_to_do"],
+  "chosenBecause": "Plan deliverable exists and passes validation",
+  "automationLevel": "semi-auto",
+  "confidence": 0.92
+}
+```
+
+**Output Format**:
+```
+--- Decision Trace: user-auth ---------------------
+[10:15] START -> pm
+  Decision: Begin PDCA cycle
+  Rationale: New feature request detected
+
+[10:20] pm -> plan
+  Decision: advance_to_plan
+  Rationale: PRD document generated successfully
+  Alternatives: [reject_prd, revise_scope]
+  Confidence: 0.88
+
+[10:30] plan -> design
+  Decision: advance_to_design
+  Rationale: Plan document complete, passes validation
+  Alternatives: [request_plan_revision, skip_to_do]
+  Confidence: 0.92
+---------------------------------------------------
+Total decisions: 3
+```
+
+### summary
+
+Show daily or weekly audit summary.
+
+1. Read audit logs for the current day (and optionally past 7 days)
+2. Aggregate by action type and count occurrences
+3. Calculate key metrics:
+   - Total actions recorded
+   - Phase transitions count
+   - Automation vs manual ratio
+   - Error/recovery events
+   - Average trust score change
+4. Display formatted summary
+
+**Output Format**:
+```
+--- Audit Summary (2026-03-19) --------------------
+Total Actions       : 45
+Phase Transitions   : 12
+Checkpoints Created : 4
+Errors Recorded     : 1
+Recoveries          : 1
+
+Action Breakdown:
+  phase_transition       : 12 (27%)
+  checkpoint_created     :  4 (9%)
+  match_rate_recorded    :  8 (18%)
+  automation_level_change:  2 (4%)
+  iteration_completed    :  6 (13%)
+  other                  : 13 (29%)
+
+Automation Ratio: 67% auto / 33% manual
+Trust Score Change: +3 (69 -> 72)
+---------------------------------------------------
+Weekly Trend (last 7 days):
+  Mon: 32 actions | Tue: 45 actions | Wed: 28 actions
+  ...
+```
+
+### search <query>
+
+Search audit logs by action type, feature name, or date range.
+
+1. Parse the search query to determine filter type:
+   - If query matches an action type (e.g., `phase_transition`), filter by action
+   - If query matches a feature name, filter by feature
+   - If query matches a date (YYYY-MM-DD), filter by date
+   - Otherwise, perform full-text search across all fields
+2. Read relevant JSONL files from `.hmcmkit/audit/`
+3. Apply filters and return matching entries (max 50 results)
+4. Display results in chronological order
+
+**Search Examples**:
+```bash
+# Search by action type
+/audit search "phase_transition"
+
+# Search by feature name
+/audit search "user-auth"
+
+# Search by date
+/audit search "2026-03-18"
+
+# Full-text search
+/audit search "error"
+```
+
