Compares two snapshots of meeting support-incident notes (source transcript + structured notes) to detect what changed between a baseline and a new version

## 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 halowerk-buerowerk-meeting-support-incident-note-snapshot-compare-a29a9cab -d '<json body>'
```

Example prompt: Compare these two sets of support incident meeting notes — here's the baseline with its transcript segments and structured notes (summary, topics, decisions, action items, open questions), and here's the updated version with the new transcript — tell me exactly what changed between them.

## When to prefer this

Choose this endpoint when you need to programmatically detect and surface structured differences between two versions of meeting incident notes — especially when both a source transcript and structured note fields (action items with owners/due dates, decisions, open questions) are available. Prefer this over generic text-diff tools when you need semantically structured deltas (e.g. which specific action items changed owner) rather than raw line diffs.

## Known failure modes

- Missing required baseline.notes fields (summary, topics, decisions, action_items, open_questions) returns a 422 validation error
- Neither segments nor transcript_package provided in baseline.source causes a schema validation failure
- Action item text or quote exceeding maxLength limits (1000/3000 chars) triggers a 400 error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Empty summary array (minItems:1 violated) returns a validation error

## Output

A JSON object describing the differences between the baseline and updated meeting note snapshots, including changes to action items (owner, due date, text), decisions, topics, summary points, and open questions — effectively a structured delta between two incident note versions.
