Victor KuznetsovandClaude Fable 4.5 e09104e39f Document Meta Muse Image Content Seal support with oracle-verified corpus 
Muse Image (muse-image-1.0, Meta Superintelligence Labs, 2026-07-07) ships
every output with Content Seal, a proprietary invisible pixel watermark, and
no visible mark. Establish support documentation and a verified corpus:

- data/contentseal/: five own generations via the Meta Model API, every
  oracle verdict recorded in manifest.csv (44 rows, settled-text protocol,
  fresh-navigation variant for calibration rows)
- Oracle: meta.ai/identification web tool only; no API endpoint exists in
  the Meta Model API (verified against dev.meta.ai/docs); internal REST
  pair documented with its server-side sliding-window rate limit
- Removal: default qwen-zimage profile clears Content Seal (oracle-verified
  on the worst source); strength floor derived at 0.1 by the standard
  worst-boundary-plus-cross-source-spread method, recorded but not encoded
  as a constant since no provenance signal routes Muse output onto a vendor
  cohort
- Seal robustness measured: survives resize, JPEG q85, metadata stripping,
  CDN WebP transcode; dies to center crops and diffusion regeneration
- tests/test_contentseal_corpus.py guards manifest integrity
