# ✅ PHASE 01 COMPLETION CHECKPOINT

**Before proceeding to Phase 02 (Test-First Design), verify ALL pre-flight validations passed:**

## Mandatory Steps Executed

- [ ] **Phase 01.0:** Project root validated (CWD is DevForgeAI project)
- [ ] **Phase 01.0.5:** CLI availability checked
- [ ] **Phase 01.1:** git-validator subagent invoked, Git status assessed
- [ ] **Phase 01.1.5:** User consent obtained (if uncommitted changes > 10)
- [ ] **Phase 01.1.6:** Stash warnings shown (if user selected stash)
- [ ] **Phase 01.2:** Git Worktree Auto-Management (if Git available + enabled)
- [ ] **Phase 01.2.5:** Dependency Graph Validation - validated or --force bypassed
- [ ] **Phase 01.2.6:** File Overlap Detection - validated or acknowledged
- [ ] **Phase 01.3:** Workflow mode determined (git-based or file-based)
- [ ] **Phase 01.4:** File-based tracking setup (if WORKFLOW_MODE == "file_based")
- [ ] **Phase 01.5:** All 6 context files validated (exist and non-empty)
- [ ] **Phase 01.6:** Story specification loaded (via @file reference)
- [ ] **Phase 01.6.5:** Story type detected, phase skip config set
- [ ] **Phase 01.7:** Spec vs. context conflicts resolved (via AskUserQuestion if conflicts)
- [ ] **Phase 01.8:** tech-stack-detector invoked, technologies validated
- [ ] **Phase 01.9:** Previous QA failures detected (recovery mode if needed)
- [ ] **Phase 01.9.5:** Structured gap data loaded (if gaps.json exists)
- [ ] **Phase 01.10:** Story complexity analyzed - user warned if HIGH/VERY HIGH

## Variables Set for Phases 02-08

- [ ] `$GIT_AVAILABLE` = true/false
- [ ] `$WORKFLOW_MODE` = "full" / "partial" / "fallback"
- [ ] `$CAN_COMMIT` = true/false
- [ ] `$WORKTREE_PATH` = (worktree path, if created)
- [ ] `$TEST_COMMAND` = (pytest / npm test / dotnet test / etc.)
- [ ] `$TEST_COVERAGE_COMMAND` = (with coverage flags)
- [ ] `$BUILD_COMMAND` = (language-specific build command)
- [ ] `$STORY_TYPE` = feature / documentation / bugfix / refactor
- [ ] `$SKIP_PHASES` = Array of phases to skip
- [ ] `$QA_*_FAILURE` = Boolean flags (if QA failure detected)
- [ ] `$REMEDIATION_MODE` = true/false (if gaps.json loaded)
- [ ] `$QA_COVERAGE_GAPS` = Array (if gaps.json has coverage gaps)
- [ ] `$QA_ANTIPATTERN_GAPS` = Array (if gaps.json has anti-patterns)
- [ ] `$QA_DEFERRAL_GAPS` = Array (if gaps.json has deferrals)

## Success Criteria

- [ ] All 6 context files exist
- [ ] No conflicts between story spec and context files
- [ ] Technology stack detected and validated
- [ ] Test commands identified and executable
- [ ] Git workflow mode determined
- [ ] User consented to git operations (if applicable)
- [ ] Ready to begin TDD workflow

## Checkpoint Validation

**IF ANY ITEM UNCHECKED:**
```
❌ PHASE 01 INCOMPLETE - Review missing steps above
⚠️  DO NOT PROCEED TO PHASE 02 until all checkpoints pass
⚠️  Missing validations will cause failures in later phases

Common issues:
  - Context files missing → Run /create-context
  - Git not initialized → Initialize git or use file-based mode
  - Spec conflicts → Resolve via AskUserQuestion
  - Tech stack mismatch → Update tech-stack.md or adjust story
```

**IF ALL ITEMS CHECKED:**
```
✅ PHASE 01 COMPLETE - All Pre-Flight Validations Passed

Variables set: {count} variables configured
Context files: 6/6 validated
Git mode: {WORKFLOW_MODE}
Test framework: {TEST_COMMAND}

Ready to begin TDD cycle.

**Update Progress Tracker:**
Mark "Execute Phase 01" todo as "completed"
