## 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 bibliographies-timestamp-order-audit-91f7e8ae -d '<json body>'
```

Example prompt: Can you audit the timestamp order for this bibliography entry — publication instant 2023-01-15T00:00:00Z, amendment instant 2023-06-01T00:00:00Z, availability window 2023-01-01 to 2024-01-01 — assessed as of 2024-03-01, for workRef 'WRK-001', corpusRef 'CORP-A', using public data class and bibliography revision 'rev-2'?

## When to prefer this

Use this endpoint when you need to verify that bibliography or literature record timestamps (publication, amendment, availability window) are in correct temporal order relative to a specific assessment instant, within a strictly pinned corpus/work/scope/style/revision frame. Prefer this over general date-validation tools when working with structured bibliography metadata that requires exact record-bound temporal auditing rather than freeform date comparison.

## Known failure modes

- Invalid or malformed datetime strings in rows or assessedAt field returns a validation error
- rows array outside 1–32 item bounds returns a schema error
- Missing required nonpersonalMetadata:true constant causes rejection
- dataClass not matching 'public' or 'synthetic' enum returns an error
- Malformed entryDigest or bibliographyRevision strings may cause processing failure
- Availability window start/end inconsistency (end before start) may return an ordering error

## 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 a timestamp order audit result indicating whether the supplied publication and amendment instants are correctly ordered relative to each other and fall within the declared half-open availability window as measured against the single assessment instant, within the pinned issuer/record/source/revision frame. This is a supplied-record analysis, not an independent certification.
