<objective>
Integrate GSD pattern analysis findings from Quick 001 into planning documents to ensure decisions and patterns are properly documented before Phase 1 execution.

Purpose: Convert the comprehensive GSD_PATTERNS.md analysis (647 lines) into actionable updates across PROJECT.md, ROADMAP.md, and REQUIREMENTS.md. This ensures key decisions, phase-specific applications, and directory structure choices are reflected in planning artifacts.

Output: Updated planning documents with GSD pattern integration complete - PROJECT.md has decisions documented, ROADMAP.md phases have concrete pattern applications, REQUIREMENTS.md reflects any pattern-suggested changes.

  <name>Update PROJECT.md Key Decisions table</name>
  <files>.planning/PROJECT.md</files>
  <action>
Read GSD_PATTERNS.md Summary section (lines 616-643) which lists 7 core adopted patterns and key adaptations for data engineering.

Update PROJECT.md Key Decisions table (lines 73-83) to reflect these pattern adoption decisions:

Add new rows for:
1. **GSD pattern adoption (XML structure)** - "XML elements for semantic clarity in LOOPS/CONTEXT templates (vs pure markdown). Enables parsing clarity and explicit task boundaries." → Outcome: "Adopted for Phase 2+ templates"

2. **GSD pattern adoption (token budgets)** - "Conservative thresholds for data engineering: 20/40/50% (vs GSD's 30/50/70%). Complex reasoning (model dependencies, SQL transformations) requires more headroom." → Outcome: "Adopted for Phase 3 context engineering"

3. **GSD pattern adoption (checkpoint thinking)** - "Agent proposes, user approves workflow. Preserves ownership while leveraging automation." → Outcome: "Adopted for Phase 2 loop capture protocol"

4. **Session artifact organization** - "Use .project/sessions/YYYY-MM-DD-description/ structure (equivalent to GSD's .planning/ but for ephemeral session work)." → Outcome: "Adopted for Phase 2 session handoff"

Update the existing "Research decides milestone structure" row outcome from "— Pending" to "Resolved: 4 phases with GSD patterns integrated per phase-specific integration roadmap".

Preserve all existing rows. Add new rows below the last existing row.

<task type="auto">
  <name>Update ROADMAP.md Phase 1-4 details with GSD integration roadmap</name>
  <files>.planning/ROADMAP.md</files>
  <action>
Read GSD_PATTERNS.md Integration Roadmap section (lines 500-614) which provides phase-specific pattern applications for Phases 1-4.

Update ROADMAP.md phase details sections (currently showing "Plans: TBD"):

**Phase 1: Foundation & Templates (lines 52-64)**
After Success Criteria, before "Plans:" line, add new section:
```markdown
**GSD Pattern Applications:**
  - XML structure for semantic clarity in template teaching examples
  - Establish .project/ artifact organization (equivalent to GSD's .planning/)
  - Goal-backward methodology (must_haves with verifiable outcomes)
  - Document XML vs markdown tradeoffs for different use cases
```

**Phase 2: Session Handoff System (lines 66-78)**
After Success Criteria, before "Plans:" line, add:
```markdown
**GSD Pattern Applications:**
  - Context layering: PROJECT_CONTEXT.md → LOOPS.md → CONTEXT.md → SESSION_SUMMARY.md
  - Fresh context windows: session export/import pattern (no within-session accumulation)
  - Checkpoint thinking: agent proposes loops → user approves (checkpoint:decision)
  - Session artifacts in .project/sessions/YYYY-MM-DD-description/ dated subdirectories
```

**Phase 3: Context Engineering Patterns (lines 80-92)**
After Success Criteria, before "Plans:" line, add:
```markdown
**GSD Pattern Applications:**
  - Conservative token budgets: 20% (2k), 40% (4k), 50% (5k) thresholds for data engineering
  - Progressive loading: start narrow (root model + deps), expand deliberately, document decisions
  - Context decision audit trail: CONTEXT_DECISIONS.md captures "why this scope?"
  - 50% rule adaptation: stop before quality degradation (GSD's core principle)
```

**Phase 4: Educational Integration & Validation (lines 94-108)**
After Success Criteria, before "Plans:" line, add:
```markdown
**GSD Pattern Applications:**
  - Inline GSD mechanics explanations (why XML, context layering, fresh windows, checkpoints)
  - Show, don't tell: templates with annotated examples (worked example with 200+ model lineage)
  - Goal-backward onboarding: must_haves → artifacts → worked example → validate
  - Attribution and learning: document adopted patterns and rationale
```

Do NOT modify the "Plans: TBD" lines - those will be updated during phase planning.

<task type="auto">
  <name>Review and update REQUIREMENTS.md based on GSD patterns</name>
  <files>.planning/REQUIREMENTS.md</files>
  <action>
Read GSD_PATTERNS.md to identify if any patterns suggest new requirements or modifications to existing v1 requirements.

Analysis needed:
1. Do GSD patterns suggest any NEW requirements not covered by existing 18 v1 requirements?
2. Should any existing requirements be enhanced with GSD pattern context?

Expected findings based on GSD_PATTERNS.md:
- Pattern 1 (XML structure): Already covered by META-01 (heavily commented templates)
- Pattern 2 (Context layering): Already covered by HANDOFF-03 (CONTEXT.md), HANDOFF-04 (session summary)
- Pattern 5 (Artifact organization): NEW - .project/sessions/ structure needs requirement
- Pattern 7 (Token budgets): Already covered by CONTEXT-02 (token budget management)

Add new requirement if .project/sessions/ artifact organization is not explicitly covered:

In "Session Handoff" section (after HANDOFF-06, before "### Context Engineering"), add:
```markdown
- [ ] **HANDOFF-07**: Session artifact organization (.project/sessions/YYYY-MM-DD-description/ structure)
```

Update Traceability section at bottom:
- Add HANDOFF-07 row: "| HANDOFF-07 | Phase 2 | Pending |"
- Update "v1 requirements: 18 total" to "v1 requirements: 19 total"
- Update "Mapped to phases: 18/18 ✓" to "Mapped to phases: 19/19 ✓"

If no new requirements needed (artifact organization already covered), add comment in REQUIREMENTS.md after v1 Requirements header explaining GSD pattern review was performed and no new requirements identified.
  </action>
  <verify>
# Check if HANDOFF-07 was added
grep "HANDOFF-07" .planning/REQUIREMENTS.md
# Should find HANDOFF-07 requirement if added

# Check if v1 count was updated (if HANDOFF-07 added)
grep "v1 requirements:" .planning/REQUIREMENTS.md
# Should show 19 total if requirement added, 18 if not

# Check traceability coverage
grep "Mapped to phases:" .planning/REQUIREMENTS.md
# Should show X/X ✓ (full coverage maintained)

# Verify GSD pattern review is documented either via new requirement or comment
grep -E "HANDOFF-07|GSD pattern.*review" .planning/REQUIREMENTS.md
# Should find evidence of review
  </verify>
  <done>REQUIREMENTS.md updated with HANDOFF-07 (session artifact organization) if needed, or documented comment explaining GSD pattern review found no gaps. Traceability section maintains full coverage (X/X mapped).</done>

After all tasks complete:

1. **Check PROJECT.md updates**:
   ```bash
   grep -A 30 "## Key Decisions" .planning/PROJECT.md | grep "GSD pattern adoption"
   ```
   Should show 3 GSD pattern rows (XML structure, token budgets, checkpoint thinking) plus session artifact organization.

2. **Check ROADMAP.md updates**:
   ```bash
   for phase in 1 2 3 4; do
     echo "=== Phase $phase ==="
     grep -A 8 "Phase $phase:" .planning/ROADMAP.md | grep -A 4 "GSD Pattern Applications"
   done
   ```
   Should show GSD Pattern Applications section for each phase with specific patterns listed.

3. **Check REQUIREMENTS.md updates**:
   ```bash
   grep -c "HANDOFF-" .planning/REQUIREMENTS.md
   ```
   Should show 7 HANDOFF requirements (HANDOFF-01 through HANDOFF-07).

4. **Verify all changes committed**:
   ```bash
   git diff --name-only .planning/PROJECT.md .planning/ROADMAP.md .planning/REQUIREMENTS.md
   ```
   Should show all three files modified.
