conductor(plan): Tier 2 autonomous sandbox - implementation plan + metadata
9 phases, 30+ tasks, scope-only (no T-shirt size per user feedback):
- Phase 1: failcount module (15 TDD tasks, 13 unit tests, 100% coverage target)
- Phase 2: failure report writer (4 sections, opt-in tests)
- Phase 3: slash command + agent + opencode.json.fragment templates (11 spec tests)
- Phase 4: run_track.py CLI entry point (duplicates slash command protocol)
- Phase 5: setup_tier2_clone.ps1 bootstrap (idempotent, -WhatIf support)
- Phase 6: run_tier2_sandboxed.ps1 launcher (restricted token skeleton v1)
- Phase 7: git hooks (pre-push refuses all pushes, post-checkout logs)
- Phase 8: opt-in tests (TIER2_SANDBOX_TESTS=1, TIER2_SMOKE=1)
- Phase 9: user guide + tracks.md registration + metadata
Key contracts:
- FailcountState dataclass with 3 signals (red/green/no_progress)
- Result-style with to_dict/from_dict for state persistence
- Atomic write via tmp + os.replace
- 3-layer enforcement: OpenCode permission system + Windows restricted token + git hooks
