EVIDENCE LAYERS
| LAYER | WHAT IT SHOWS | HERE | STATE |
|---|---|---|---|
| 1 · Signature | The key holder signed these exact bytes | Ed25519 key promptreports-ai#1, checked at ingest | VALID AT INGEST |
| 2 · Log inclusion | The record is a leaf of an RFC 6962 tree under a signed checkpoint | leaf 31 of 46 in a signed checkpoint | PROVED |
| 3 · Outside cosigners | Independent witnesses saw no fork or rollback of the log | 0 of 2 required independent cosignatures (quorum not met) | QUORUM NOT MET |
| 4 · Qualified time | A timestamp authority dated the daily root that includes the record | 2 verified timestamps, none eIDAS qualified | NOT QUALIFIED |
| 5 · Bitcoin anchor | The daily root existed by a Bitcoin block, through OpenTimestamps | block 975532 | ANCHORED |
Each layer stands on its own. The signature, the log proof, the timestamps and the Bitcoin anchor check from the export bundle alone; cosignatures check against each witness's own key.

OUTSIDE COSIGNERS
Who checked the log
policy2 independent cosignatures required; a witness run by the registry's operator never counts · tlog-policy file NOT MET
No witness is configured for this log yet.
A cosignature means the witness checked that this checkpoint extends every earlier one it saw. It is not an endorsement of this record.

WHAT THIS PROVES
- The record body with this SHA-256 digest existed no later than the appended time, and no later than the timestamp authority's time on the root that includes it.
- The holder of the listed signing key signed exactly these bytes.
- The record sits at this position in an append-only log whose signed checkpoints and daily roots are published outside the registry.
WHAT THIS DOES NOT PROVE
- That the record's contents are true.
- Who authored the underlying work: a signature shows who signed, not who wrote.
- Anything about the private content behind a hash-only record (evidence, incident) beyond its hash.
