## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability study-notes-provenance-edge-audit-30b2ad0e -d '<json body>'
```

Example prompt: Audit the provenance edges between these 5 study notes and their 5 source references — I need you to check that the declared byte spans match the source revision and digest pins I've provided, using public data class and nonPersonalMetadata set to true.

## When to prefer this

Choose this endpoint when you need to verify that declared byte-span edges between study notes and their source references are consistent with revision/digest pins and byte bounds — without needing to read or prove quotation support from raw source bytes. Ideal for offline, typed, non-personal metadata validation workflows where lightweight provenance integrity checks are sufficient and full content verification is not required.

## Known failure modes

- Missing required nonpersonalMetadata:true flag causes rejection
- Array lengths for notes, edges, or sources exceed maxItems:32 limit
- Invalid dataClass value (must be 'public' or 'synthetic') returns validation error
- Malformed or missing revision/digest pin values in edges cause audit failure
- Empty arrays (minItems:1 not met) for notes, edges, or sources return 400-level error

## How this service works

Check declared note-to-source byte spans against source revision/digest pins and byte bounds. Does not read source bytes or prove quotation support. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns an audit result for each declared note-to-source provenance edge, indicating whether the byte spans fall within declared bounds and whether revision/digest pins match. Does not read or validate actual source byte content. Includes a receipt; full result retained for 24 hours, minimal receipt metadata for 90 days.
