feat(phase-91): JoinIR Selfhost depth-2 advancement - Pattern P5b design & planning
## Overview
Analyzed 34 loops across selfhost codebase to identify JoinIR coverage gaps.
Current readiness: 47% (16/30 loops). Next frontier: Pattern P5b (Escape Handling).
## Current Status
- Phase 91 planning document: Complete
- Loop inventory across 6 key files
- Priority ranking: P5b (escape) > P5 (guard) > P6 (nested)
- Effort estimates and ROI analysis
- Pattern P5b Design: Complete
- Problem statement (variable-step carriers)
- Pattern definition with Skeleton layout
- Recognition algorithm (8-step detection)
- Capability taxonomy (P5b-specific guards)
- Lowering strategy (Phase 92 preview)
- Test fixture: Created
- Minimal escape sequence parser
- JSON string with backslash escape
- Loop Canonicalizer extended
- Capability table updated with P5b entries
- Fail-Fast criteria documented
- Implementation checklist added
## Key Findings
### Loop Readiness Matrix
| Category | Count | JoinIR Status |
|----------|-------|--------------|
| Pattern 1 (simple bounded) | 16 | ✅ Ready |
| Pattern 2 (with break) | 1 | ⚠️ Partial |
| **Pattern P5b (escape seq)** | ~3 | ❌ NEW |
| Pattern P5 (guard-bounded) | ~2 | ❌ Deferred |
| Pattern P6 (nested loops) | ~8 | ❌ Deferred |
### Top Candidates
1. **P5b**: json_loader.hako:30 (8 lines, high reuse)
- Effort: 2-3 days (recognition)
- Impact: Unlocks all escape parsers
2. **P5**: mini_vm_core.hako:541 (204 lines, monolithic)
- Effort: 1-2 weeks
- Impact: Major JSON optimization
3. **P6**: seam_inspector.hako:76 (7+ nesting)
- Effort: 2-3 weeks
- Impact: Demonstrates nested composition
## Phase 91 Strategy
**Recognition-only phase** (no lowering in P1):
- Step 1: Design & planning ✅
- Step 2: Canonicalizer implementation (detect_escape_pattern)
- Step 3: Unit tests + parity verification
- Step 4: Lowering deferred to Phase 92
## Files Added
- docs/development/current/main/phases/phase-91/README.md - Full analysis & planning
- docs/development/current/main/design/pattern-p5b-escape-design.md - Technical design
- tools/selfhost/test_pattern5b_escape_minimal.hako - Test fixture
## Files Modified
- docs/development/current/main/design/loop-canonicalizer.md
- Capability table extended with P5b entries
- Pattern P5b full section added
- Implementation checklist updated
## Acceptance Criteria (Phase 91 Step 1)
- ✅ Loop inventory complete (34 loops across 6 files)
- ✅ Pattern P5b design document ready
- ✅ Test fixture created
- ✅ Capability taxonomy extended
- ⏳ Implementation deferred (Step 2+)
