Victor Kuznetsov 464fd142ea Add audio and video watermark benchmark oracles, cohorts, and research studies
Extend the development-only benchmark family from images to audio and
video, and close four research directions from the watermark-landscape
map with local, revision-pinned evidence.

Benchmark schema: media_type audio and video rows, audioseal and
videoseal adapters with media-checked adapter binding, sample-domain
audio fidelity (SNR with unbounded_identical), frame-domain video
fidelity (mean PSNR, changed-frame fraction), and per-frame temporal
evidence in videoseal detection records. The report accepts all three
media types and carries SNR columns.

Audio: shared pinned AudioSeal oracle, synthetic and system-voice
speech cohorts with matched negatives, codec, noise, removed, and
forged arms, and the provenance experiment proving visual-only video
cleaning leaves the audio bitstream and watermark verdict invariant.

Video: TorchScript-only VideoSeal oracle (the pip package is unusable
on macOS arm64 and its loader resolves paths relative to cwd), video
cohort with crf/scale/fps attacks and four-state arms, temporal
evaluation measuring the crf decay curve, the frame-aggregation matrix
(computed locally after finding the TorchScript build ignores the
aggregation argument), and real provider clips as carriers.

Forgery: double-embedding study showing the last writer wins completely
under both oracles, scoped remover-trace probe, and the forged/
removed cohort arms encoding each scheme's correct expected verdict
(presence rule for audioseal, message rule for videoseal).

C2PA resolution: measured the five vendors' resolver contracts and the
C2PA 2.2 18.10.5 privacy gradient; product decision recorded that this
tool never resolves over the network. A registry guard pins the
published resolution-API set.

Gate: ruff and pyright src/ clean, 2114 passed / 3 skipped; maintain.sh
stops only on the known unfixed lightning 2.6.5 CVEs, pre-existing.

Documentation

This documentation is split by purpose. Start with the user guides if you want to run the tool. Use the maintainer references only when changing the code.

User guides

Page Use it when
Installation You need the CLI, an optional model backend, or a development environment.
CLI guide You want a command for an image, video metadata or visible marks, a directory, or a specific watermark type.
Python API You want to call the package from Python.
Supported signals You need to know which visible marks, metadata formats, and invisible signals are covered.
Known limitations You need the quality, device, format, or verification boundaries.
Photo pixel classification You want classify / classify_pixels: AI versus camera, optional provider.
Photo classifier training You need the retrain pack, public sources, and what is not published.
Scope, safety, and legal notes You need the intended use and legal context.

Research archive

These pages record experiments and the evidence behind past decisions. They are not command references and may describe prototypes that were later removed. The current behavior is defined by the code, tests, README, and user guides.
