# Production completion

Declare the finished result and material-state deduplication rules.

An optional `outcome` field declares the finished result required by this exact Project Type version:

```json
{"outcome":{"type":"export","dedupe":"material_project_state","minimumDurationSec":3}}
```

`type` is `export`, `delivery`, or `project_outcome`. `dedupe`, when present, must be `material_project_state`; that is also its default. `minimumDurationSec` is optional, finite, between 0 and 86,400 seconds. A positive minimum requires host-measured media duration. Omit it for text or editable project artifacts.

Configure this in **Project defaults & starting questions → Production completion**. Omitting `outcome` preserves the existing host completion behavior. These settings never launch exports, create revenue or mark a client action as successful. Version the Project Type when changing its production rule.

Only a trusted completion adapter can supply `materialStateHash`, measured duration, success, retained-source lineage and the actual outcome kind. The accounting qualifier reads the rule from the exact released Project Type; browser-provided contributors and success flags are not accepted. Matching material states deduplicate under the payer-period policy. Verified editable-project deliveries can satisfy `project_outcome`; a local MP4 upload alone does not prove an executed media export.
