# Format Field Coverage Matrix

Last generated: 2026-06-03

This file is generated from the schema inventory in `docs/api/provider-interface-definitions.md` and gives every documented schema field an explicit handling status. “处理到” here means the field is either mapped, preserved in same-format paths, rejected with a structured fail-closed error, or explicitly outside the current conversion surface. It does not mean every field can be cross-format converted.

Provider schema updates do not require immediate conversion-code changes for runtime safety. Same-format runtime paths bypass canonical conversion, and same-format canonical roundtrip preserves provider extension fields. Cross-format conversion only enables fields with an audited semantic mapping; newly discovered or unknown provider fields default to structured fail-closed behavior until mapped.

Regenerate with: `python3 docs/api/generate_format_field_coverage.py`.

Statuses used in this matrix: `native`, `mapped`, `mapped/lossy-blocked`, `extension-preserved`, `unaudited`, `unsupported`, `invalid-enum`, `lossy-blocked`, `not-in-conversion-surface`.
