Raw receipts
C2PA reader
The same engine as the vendor pages, but framed for what it fundamentally is: a inspector for Content Credentials — who signed a file, what actions were recorded, and whether provenance is missing from a file that should have it.

Quick answer
C2PA (Content Credentials) is the open ISO standard journalists use to trace a file's history. This reader decodes its manifest store: the claim (generator, format, title), the action list (created, edited, saved — with timestamps and software agents), and the cryptographic signature box. Remember the two honest curves: an intact manifest is strong evidence; a missing manifest is weak evidence — metadata is easy to lose and also easy to strip.Interpreting the two failure modes
| Observation on a file from a marking vendor | Likely meaning |
|---|---|
Manifest present, actions show created | Straight from the generator (or carefully preserved) |
Manifest present, actions show edited/converted | One or more editing tools processed it after generation — read the trail |
| No manifest at all | Never had one or stripped downstream (screenshots, messengers, careless re-saves) |
| Manifest present but claim text is odd | Inspect the generator strings below the tool — we surface them raw on purpose |
