Attestations are saved in the JSON-serialized [Sigstore bundle][6] format.

If multiple subjects are being attested at the same time, each attestation will
be written to the output file on a separate line (using the [JSON Lines][7]
format).
If multiple subjects are being attested at the same time, a single attestation
will be created with references to each of the supplied subjects.

## Attestation Limits

### Subject Limits

No more than 2500 subjects can be attested at the same time. Subjects will be
processed in batches 50. After the initial group of 50, each subsequent batch
will incur an exponentially increasing amount of delay (capped at 1 minute of
delay per batch) to avoid overwhelming the attestation API.
No more than 1024 subjects can be attested at the same time.

### Identify Multiple Subjects

If you are generating multiple artifacts, you can generate a provenance
attestation for each by using a wildcard in the `subject-path` input.
If you are generating multiple artifacts, you can attest all of them at the same
time by using a wildcard in the `subject-path` input.
