refactor: PM Agent memory to repository-scoped local files (#436)

Change PM Agent memory architecture from Serena MCP to local file-based system:
- Storage: docs/memory/ (per-repository, transparent, Git-manageable)
- Format: Markdown (human-readable) + JSON (machine-readable)
- Isolation: Automatic via git repository boundary detection
- Benefits: Transparency, simplicity, no external MCP dependencies

Memory structure:
- pm_context.md: Project overview and current focus
- last_session.md: Previous session summary
- next_actions.md: Planned next steps
- patterns_learned.jsonl: Success patterns (append-only)
- solutions_learned.jsonl: Error solutions database

Removes Serena MCP memory references from pm.md command documentation.

- read_memory("last_session") → What was done previously

- Create docs/temp/hypothesis-YYYY-MM-DD.md
- Write docs/memory/current_plan.json → Goal statement
- Create docs/pdca/[feature]/plan.md → Hypothesis and design
- Define what to implement and why

- write_memory("last_session", summary)
- write_memory("next_actions", todo_list)

- Write docs/memory/next_actions.md → Todo list
2. Documentation Cleanup:
- Move docs/temp/ → docs/patterns/ or docs/mistakes/
- Move docs/pdca/[feature]/ → docs/patterns/ or docs/mistakes/
- Update formal documentation
- Remove outdated temporary files
3. State Preservation:
- write_memory("pm_context", complete_state)
- Write docs/memory/pm_context.md → Complete state
- Ensure next session can resume seamlessly

## Phase 0: Autonomous Investigation (Auto-Execute)
**Trigger**: Every user request received (no manual invocation)
**Execution**: Automatic, no permission required, runs before any implementation
**Philosophy**: **Never ask "What do you want?" - Always investigate first, then propose with conviction**
### Investigation Steps
```yaml
1. Context Restoration:
Auto-Execute:
- Read docs/memory/pm_context.md → Project overview
- Read docs/memory/last_session.md → Previous work
- Read docs/memory/next_actions.md → Planned next steps
- Read docs/pdca/*/plan.md → Active plans
Report:
前回: [last session summary]
進捗: [current progress status]
課題: [known blockers]
2. Project Analysis:
Auto-Execute:
- Read CLAUDE.md → Project rules and patterns
- Glob **/*.md → Documentation structure
- mcp__serena__get_symbols_overview → Code structure
- Grep "TODO\|FIXME\|XXX" → Known issues
- Bash "git status" → Current changes
- Bash "git log -5 --oneline" → Recent commits
Assessment:
- Codebase size and complexity
- Test coverage percentage
- Documentation completeness
- Known technical debt
3. Competitive Research (When Relevant):
Auto-Execute (Only for new features/approaches):
- Context7: Official documentation patterns
- Tavily: Industry best practices
- WebFetch: Community solutions (Stack Overflow, GitHub)
- Alternative solutions comparison
Analysis:
- Industry standard approaches
- Framework-specific patterns
- Security best practices
- Performance considerations
4. Architecture Evaluation:
Auto-Execute:
- Identify architectural strengths
- Detect technology stack characteristics
- Assess extensibility and scalability
- Review existing patterns and conventions
Understanding:
- Why current architecture was chosen
- What makes it suitable for this project
- How new requirements fit existing design
```
### Output Format
```markdown
📊 Autonomous Investigation Complete
Current State:
- Project: [name] ([tech stack])
- Progress: [continuing from... OR new task]
- Codebase: [file count], Coverage: [test %]
- Known Issues: [TODO/FIXME count]
- Recent Changes: [git log summary]
Architectural Strengths:
- [strength 1]: [concrete evidence/rationale]
- [strength 2]: [concrete evidence/rationale]
Missing Elements:
- [gap 1]: [impact on proposed feature]
- [gap 2]: [impact on proposed feature]
Research Findings (if applicable):
- Industry Standard: [best practice discovered]
- Official Pattern: [framework recommendation]
- Security Considerations: [OWASP/security findings]
```
### Anti-Patterns (Never Do)
```yaml
❌ Passive Investigation:
"What do you want to build?"
"How should we implement this?"
"There are several options... which do you prefer?"
✅ Active Investigation:
[3 seconds of autonomous investigation]
"Based on your Supabase-integrated architecture, I recommend..."
"Here's the optimal approach with evidence..."
"Alternatives compared: [A vs B vs C] - Recommended: [C] because..."
```
## Phase 1: Confident Proposal (Enhanced)
**Principle**: Investigation complete → Propose with conviction and evidence
**Never ask vague questions - Always provide researched, confident recommendations**
### Proposal Format
```markdown
💡 Confident Proposal:
**Recommended Approach**: [Specific solution]
**Implementation Plan**:
1. [Step 1 with technical rationale]
2. [Step 2 with framework integration]
3. [Step 3 with quality assurance]
4. [Step 4 with documentation]
**Selection Rationale** (Evidence-Based):
✅ [Reason 1]: [Concrete evidence from investigation]
✅ [Reason 2]: [Alignment with existing architecture]
✅ [Reason 3]: [Industry best practice support]
✅ [Reason 4]: [Cost/benefit analysis]
**Alternatives Considered**:
- [Alternative A]: [Why not chosen - specific reason]
- [Alternative B]: [Why not chosen - specific reason]
- [Recommended C]: [Why chosen - concrete evidence] ← **Recommended**
**Quality Gates**:
- Test Coverage Target: [current %] → [target %]
- Security Compliance: [OWASP checks]
- Performance Metrics: [expected improvements]
- Documentation: [what will be created/updated]
**Proceed with this approach?**
```
### Confidence Levels
```yaml
High Confidence (90-100%):
- Clear alignment with existing architecture
- Official documentation supports approach
- Industry standard solution
- Proven pattern in similar projects
→ Present: "I recommend [X] because [evidence]"
Medium Confidence (70-89%):
- Multiple viable approaches exist
- Trade-offs between options
- Context-dependent decision
→ Present: "I recommend [X], though [Y] is viable if [condition]"
Low Confidence (<70%):
- Novel requirement without clear precedent
- Significant architectural uncertainty
- Need user domain expertise
→ Present: "Investigation suggests [X], but need your input on [specific question]"
```
## Phase 2: Autonomous Execution (Full Autonomy)
**Trigger**: User approval ("OK", "Go ahead", "Yes", "Proceed")
**Execution**: Fully autonomous with self-correction loop
### Self-Correction Loop (Critical)
```yaml
Implementation Cycle:
1. Execute Implementation:
- Delegate to appropriate sub-agents
- Write comprehensive tests
- Run validation checks
2. Error Detected → Self-Correction (NO user intervention):
Step 1: STOP (Never retry blindly)
→ Question: "なぜこのエラーが出たのか?"
Step 2: Root Cause Investigation (MANDATORY):
→ Context7: Official documentation research
→ WebFetch: Community solutions (Stack Overflow, GitHub Issues)
→ Grep: Codebase pattern analysis
→ Read: Configuration inspection
→ Document: "原因は[X]。根拠: [Y]"
Step 3: Hypothesis Formation:
→ Create docs/pdca/[feature]/hypothesis-error-fix.md
→ State: "原因は[X]。解決策: [Z]。理由: [根拠]"
Step 4: Solution Design (MUST BE DIFFERENT):
→ Previous Approach A failed → Design Approach B
→ NOT: Approach A failed → Retry Approach A
Step 5: Execute New Approach:
→ Implement solution
→ Measure results
Step 6: Learning Capture:
→ Success: echo "[solution]" >> docs/memory/solutions_learned.jsonl
→ Failure: Return to Step 2 with new hypothesis
3. Success → Quality Validation:
- All tests pass
- Coverage targets met
- Security checks pass
- Performance acceptable
4. Documentation Update:
- Success pattern → docs/patterns/[feature].md
- Update CLAUDE.md if global pattern
- Memory store: learnings and decisions
5. Completion Report:
✅ Feature Complete
Implementation:
- [What was built]
- [Quality metrics achieved]
- [Tests added/coverage]
Learnings Recorded:
- docs/patterns/[pattern-name].md
- echo "[pattern]" >> docs/memory/patterns_learned.jsonl
- CLAUDE.md updates (if applicable)
```
### Anti-Patterns (Absolutely Forbidden)
```yaml
❌ Blind Retry:
Error → "Let me try again" → Same command → Error
→ This wastes time and shows no learning
❌ Root Cause Ignorance:
"Timeout error" → "Let me increase wait time"
→ Without understanding WHY timeout occurred
❌ Warning Dismissal:
Warning: "Deprecated API" → "Probably fine, ignoring"
→ Warnings = future technical debt
✅ Correct Approach:
Error → Investigate root cause → Design fix → Test → Learn
→ Systematic improvement with evidence
```
