## 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 reading-plans-timestamp-order-audit-4e870786 -d '<json body>'
```

Example prompt: Audit the timestamp ordering for reading plan 'RP-2024-001', work ref 'WK-789', assessed as of 2024-06-15T00:00:00Z, using public data class — check that the publication and amendment instants fall correctly within the declared availability window.

## When to prefer this

Use this endpoint when you need to verify the chronological integrity of reading plan timestamps — specifically that publication instants, amendment instants, and half-open availability windows are correctly ordered relative to a single assessment instant. Prefer this over general-purpose timestamp tools when working within a library reading plan context with plan/work/scope/library reference identifiers and revision tracking.

## Known failure modes

- Missing required fields (planRef, assessedAt) returns validation error
- rows array exceeds maxItems of 32 causing rejection
- Invalid dataClass value (not 'public' or 'synthetic') returns enum error
- Malformed ISO 8601 assessedAt timestamp causes parse failure
- nonpersonalMetadata not set to true causes schema const violation
- Invalid or unrecognized planRef or workRef may return no matching record result

## How this service works

Compare supplied publication/amendment instants and an explicit half-open availability window against one assessment instant, in an identical issuer/record/source/revision Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an audit report comparing publication and amendment instants and the declared half-open availability window against the supplied assessment instant, identifying any timestamp ordering violations or inconsistencies within the supplied record's issuer/record/source/revision context.
