## Detailed Status Notes

### ADR-0001: Two-Tier ADR System

**Status**: Verified (40)

- ✅ Local ADR directory established at `docs/development/adr/`
- ✅ Ecosystem ADRs synced to `docs/crucible-py/architecture/decisions/`
- ✅ ADR README with index and guidance
- ✅ Template available from Crucible
- ✅ 4 local ADRs + 5 ecosystem ADRs tracked

**Evidence**:

- 4 local decision records documented
- Clear separation between local (Python-specific) and ecosystem (cross-language) decisions
- Promotion path documented in ADR README

### ADR-0002: Triple-Index Catalog Strategy

**Status**: Verified (40)

- ✅ Country catalog with three indexes (alpha2, alpha3, numeric)
- ✅ Case-insensitive matching
- ✅ Numeric zero-padding (e.g., "76" → "076")
- ✅ O(1) lookup performance
- ✅ Lazy loading with precomputed indexes

**Evidence**:

- `foundry/catalog.py` implementation with triple indexes
- 227 foundry tests (95%+ coverage)
- API parity with gofulmen v0.1.1 verified

**Related Local ADRs**:

- [ADR-0001](ADR-0001-fulmencatalogmodel-populate-by-name.md) - Python-specific populate_by_name pattern

### ADR-0003: Progressive Logging Profiles

**Status**: Verified (40)

- ✅ SIMPLE profile (text output, stderr, zero config)
- ✅ STRUCTURED profile (JSON output, core envelope fields)
- ✅ ENTERPRISE profile (full 20+ field envelope, policy enforcement)
- ✅ CUSTOM profile (user-defined configuration)
- ✅ Unified `Logger()` factory with profile selection

**Evidence**:

- `logging/` module with 4 profiles implemented
- `logging/profiles.py` with profile definitions
- `logging/policy.py` for enforcement
- Comprehensive middleware pipeline (correlation, redaction, throttling)
- Multiple sinks (Console, File, RollingFile, Memory)
- 200+ logging tests

### ADR-0004: Schema-Driven Config Hydration

**Status**: Implemented (30)

- ✅ Layer 1: Crucible defaults embedded
- ✅ Layer 2: User overrides from `~/.config/fulmen/`
- ⚠️ Layer 3: BYOC (Bring Your Own Config) partially implemented
  - ✅ ASCII terminal overrides support BYOC
  - ⚠️ Some modules need explicit BYOC API

**Evidence**:

- `config/loader.py` with three-layer loading
- `config/merger.py` for deep merge
- Crucible assets synced and embedded
- ASCII module demonstrates full three-layer pattern

**Next Steps**:

- Expose BYOC APIs consistently across all config-driven modules
- Document BYOC patterns in config module documentation

### ADR-0005: CamelCase to Language Conventions

**Status**: Verified (40)

- ✅ All models use snake_case externally
- ✅ Pydantic handles CamelCase ↔ snake_case conversion
- ✅ `populate_by_name=True` in FulmenCatalogModel for flexible deserialization
- ✅ JSON schemas use camelCase, Python uses snake_case

**Evidence**:

- All data models inherit from Fulmen foundation models
- Pydantic `ConfigDict` with `populate_by_name=True` where needed
- Consistent snake_case throughout Python codebase
- Interop with gofulmen (camelCase) and tsfulmen verified

**Related Local ADRs**:

- [ADR-0001](ADR-0001-fulmencatalogmodel-populate-by-name.md) - Python-specific populate_by_name decision

## Coverage Summary

**Total Tests**: 615 passing

## Requesting ADR Updates

If you notice PyFulmen's implementation status has changed:

1. Update this document with the new status and evidence
2. Open a GitHub issue or PR documenting the change
3. If promoting from implemented → verified, include test coverage and production usage evidence
4. Notify Crucible maintainers if ecosystem ADR needs updating
