## 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 meeting-records-revision-delta-98087e93 -d '<json body>'
```

Example prompt: Compare the meeting record metadata between revision 'rev-2024-03-01' and revision 'rev-2024-03-15' using public data class, and tell me what changed in the agenda, digest, source-segment, and owner-role fields across up to 20 records in each snapshot.

## When to prefer this

Choose this endpoint when you need a structured, privacy-safe comparison of closed meeting decision metadata between two specific revision snapshots. It is ideal for governance, audit, and change-tracking workflows that require diffing agenda, digest, source-segment, and owner-role fields without processing transcripts or personal identity data. Prefer it over general document diff tools when working with typed nonpersonal meeting record metadata in public or synthetic data classes.

## Known failure modes

- Before array is empty or missing (minItems:1 violation) — request rejected
- After or before revision strings missing — delta cannot be computed
- dataClass not one of 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Array exceeds 32 items — truncation or rejection
- Revision identifiers not found or mismatched — empty or error delta returned

## How this service works

Compare closed decision metadata between two source revisions, reporting digest, agenda, source-segment and owner-role changes. No transcript processing, agreement inference or person identity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

A structured delta map highlighting changes between two revisions of meeting record metadata, specifically covering digest, agenda, source-segment, and owner-role fields. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days. No transcript content, agreement inference, or personal identity data is included.
