## Scope

Models reviewed:

- `qpi`

The field-level machine matrix is stored in `sources/evidence_coverage.matrix.json`.

## Coverage Method

Each required model field is classified by:

- `support_type`
- `coverage_status`
- supporting `excerpt_ids`

Support type values:

- `direct_source`
- `derived_from_source`
- `product_decision`
- `red_team_inference`
- `owner_decision`

Coverage status values:

- `supported`
- `partially_supported`
- `derived`
- `unsupported`
- `needs_owner_review`

## QPI Summary

Directly supported fields include:

- `model_name`
- `one_sentence_definition`
- `core_mechanism`

Derived or productized fields include:

- `model_type`
- `pipeline_position`
- `input_types`
- `output_types`
- `trigger_keywords`
- `negative_triggers`
- `output_contract`

Owner / CCRA review fields include:

- `status`
- `selection_priority`
- `confidence_level`
- `stability_profile`
- `regression_status`

No required field is currently marked `unsupported`.

## Intellectual Archaeology Summary

Directly supported fields include:

- `model_name`
- `one_sentence_definition`
- `core_mechanism`

Derived or productized fields include:

- `model_type`
- `pipeline_position`
- `input_types`
- `output_types`
- `trigger_keywords`
- `negative_triggers`
- `output_contract`

Owner / CCRA review fields include:

- `status`

- `regression_status`

No required field is currently marked `unsupported`.

## Review Conclusion

Evidence coverage is now explicit enough for content review.

This does not mean all fields are source-direct. It means source-backed, derived, productized, red-team, and owner-decision fields are separated for review.
