# Stage: polish

## Purpose

Run Audita polishing on base transcript and produce polished transcript.

## Inputs

- `transcripts/base.json`
- `inputs/glossary.yml`

## Outputs

- `transcripts/polished.json`
- optional `artifacts/audita.report.json`

## Key Behavior

- resolves base transcript from merge outputs/canonical fallback.
- invokes an Audita runner configured with static model/runtime options; the
  invocation supplies paths and modules.
- validates processed transcript structure (`segments` array required).
- validates optional report JSON.
- materializes canonical outputs; records logs/generated config and adapter metadata.

## Invariants

- polished transcript schema validation is mandatory.
- report output is config-gated.

## Related Contracts And Tests

- [Audita](../integrations/audita.md) owns subprocess, validation, and failure
  semantics.
- [Configuration](../config.md#pipeline) owns operator-selected Audita values.
- Implementation and tests: `internal/stage/polish.go`,
