# Donna integration contract
Donna remains responsible for collecting organizational information, deciding
priority, selecting a character, and writing the final canonical script. Local
Voice is an optional audio dependency responsible for rendering and validating
that script.
## Invocation
Donna supplies:
- voice profile ID;
- canonical Markdown or Ryan-labelled dialogue;
- absolute output path;
- pronunciation overrides when needed;
- optional delivery, role, signature-asset, and pause metadata.
Donna then asks Local Voice to:
1. run `doctor` if runtime health is unknown;
2. build or validate the render plan;
3. render with `--resume`;
4. return the final audio and QA-report paths.
## Required behavior
- Do not send Markdown headings, numbered section titles, speaker labels, or
stage directions as spoken text.
- Keep greetings and closings as short standalone paragraphs so Local Voice can
preserve native tempo.
- Keep substantive paragraphs to complete sentence groups of roughly 2042
words unless a profile specifies otherwise.
- Use canonical `text` for the written brief and `tts_text` only for local
pronunciation corrections.
- Do not silently fall back to ElevenLabs. If Local Voice fails, Donna should
report the failure and apply the caller's configured fallback policy.
- Attach or link the final audio alongside the full written organizational
brief; the audio is a quick summary, not the sole record.
## Character mapping
| Donna character | Local Voice profile |
|---|---|
| Production Donna | `donna` |
| Chris Engineer | `chris-engineer` |
| Grandpa Bomber | `grandpa-bomber` |
| Pitch Meeting | `ryan-pitch-meeting` |
| Val Holiday | `val-holiday` |
## Example handoff
```json
{
"voice": "val-holiday",
"script": "/absolute/path/val-brief.md",
"output": "/absolute/path/val-brief.mp3",
"fallback": "report-and-return-text"
}
```
Local Voice returns the final audio path, QA report path, duration, and
segment-level completeness and cadence results.
