Reachable c2pa.soft-binding assertions now surface their exact alg and the
bounded printable block value next to the normalized vendor label; a value
without its algorithm stays hidden because it cannot be attributed.
com.microsoft.invismark.1 uses that value as the pixel-watermark identifier
in Microsoft Paint output, so identify names it, metadata carries it, and an
InvisMark soft binding keeps the invisible-removal gate fail-safe even after
C2PA asset binding goes invalid. Content fingerprints still do not trigger
pixel regeneration. Removal is verified against Microsoft's Content
Provenance Detection API, which reports Watermark and C2PA separately; the
protocol and the pixel-identical control requirement are documented.
Implemented in a parallel session; verified, gated, and committed by pi.
pre-commit: 1) maintain.sh - exit 1 on the known uv-secure lightning PYSEC-2026-3624 triage (no fix available, unchanged from 0.29.0); ruff, pyright src/, and 1391 tests passed separately; 2) /simplify - single-pass, clean; 3) docs sync - five docs updated by the author session, no remaining references found; 4) CLAUDE.md - invariants recorded in module-internals, no change needed
The Space demo is deployed from wiltodelta/raiw-hf-space: its uv lock pins the
library version, its sync workflow mirrors the files, and a factory reboot
alone re-installs the pinned version rather than upgrading. Document the manual
pin bump, the smoke-test CI in that repository, and live-call verification of
the running Space.

Tile the Qwen VAE donor the same way as the global pass. Glyph restore already runs on the blended full frame, so the old tile ban was an artificial gate.
verified:true may attest machine-verified geometry (stability-gated
boxes inside caps) set by a service; the pipeline consumes box/script
only, text is advisory, so the verification burden is on the geometry.
Move the draft-annotation logic (PaddleOCR line detection, word-box
grouping, three script-chosen recognition engines, crop-jitter
stability gate) from the evaluation-only scripts into the installable
package, with lazy paddle imports and a text-draft extra (CPU, no
torch). draft_text_lines() returns accepted (crop-stable, NEVER
ground-truth-correct - precision on the reference posters was 90.0% /
94.4%) and rejected proposals; source_pixel_sha256 is re-exported for
manifest building. scripts/infer_text_lines.py now dogfoods the
package module instead of loading the eval script by path.
The resolution curve's 0.154 top left the 4.33 MP CJK-sign fixture
SynthID-detected x3 in Gemini on the full production path (visible
stage -> qwen-zimage seed 0 -> resize-back -> metadata strip), with a
valid pixel-identical stripped control in the same session
(2026-08-18). Google-provenance content now resolves to the flat
QWEN_ZIMAGE_GOOGLE_STRENGTH 0.30 floor instead of the area curve -
anchors at 0.30 measured clean in Gemini on two fixtures (CJK sign +
18-face) at 3/3 checks across two work accounts, and stayed clean
under the vae-glyphs donor layer. openai/unknown content keeps the
curve; an explicit strength still wins.
The engine forwards the new kwarg into WatermarkRemover.remove_watermark,
which rejected it with TypeError on the real (non-fake) path - caught by
the deployed Modal smoke test, not by the unit fakes.
The whole-frame 15% Qwen-VAE blend returned detector-visible OpenAI
SynthID on poster-scale manifests through the engine text-manifest
path (official Content Provenance API, 2026-08-19: restored detected
x6 with the anchor, clean x6 without it; base outputs clean x6;
pixel-identical stripped controls detected, proving the pixel channel).
Add fidelity_anchor=False to remove_watermark and InvisibleOptions and
--fidelity-anchor on the CLI to reproduce the 0.27.0 research
behavior. Text-box MAE cost of the new default is under one point on
all three fixtures (11.60->11.72, 7.79->7.86, 7.57->8.13).
Issue #84: text, tables, and UI screenshots are the worst case for
--force regeneration. Document that the default pipeline skips the
invisible stage without a detectable signal, that visible/metadata
stages never redraw glyphs, and why paste-back is not offered.
The finding lived only in the research archive, whose own banner says it may
describe prototypes that were later removed. It belongs where users read
limitations: the path strips every metadata marker while copying the audio
bitstream byte for byte, so a clean local report on a clip with generated audio
is unproven rather than a guarantee.

Everything here is evidence and state, not behavior: the shipped operating point
is untouched at 512 px / 12 fps / noise_std=0.15.
The carrier was downloaded and its sha256 matched the manifest, so its properties
are now measured rather than assumed: 1920x1080 at 24 fps with an AAC audio track.
Those three fields go into the two 2026-07-31 rows, which could not previously
tell a reader what the downscale factor even was.
The geometry prize is measured end to end for the first time. Against the
untouched source, 1024 scores +3.46 dB over the shipped 512, while the entire
noise_std axis is worth 1.92 dB. Two readings that the table alone hides are
recorded with it: the temporal residual IMPROVES with resolution, because the
shared noise field lives on the latent grid and is four times finer relative to
the frame at 1920; and the frame-rate arm cannot be judged by these metrics at
all, since they price its cost and not the smoothness it buys.
Two findings that outrank the quality question. The certified row does not
reproduce -- a rerun of the same configuration on a different device and dtype
gives a different hash and different metrics, and the manifest records neither.
And the pipeline copies audio byte for byte while stripping every metadata
marker, so it can emit a file our own detector calls clean with an untouched
Google-generated audio track inside it. The mechanism is proven on two carriers;
whether that audio carries a mark the verifier reads is not, and only the oracle
can say.
The six prepared oracle submissions were never run: file upload to the verifier
failed at the tool level. Their artifacts are gone with the scratch directory,
which is the intended lifecycle for generated media, and the document says what
rebuilding costs.

Each Haar pass is one flat pywt.downcoef call over a raveled strip instead of
pywt.dwt(..., axis=1)[0], and the plane is walked in strips so no full-plane
float64 intermediate exists. Exact only while the last axis is even, so
_approximation raises on an odd width rather than returning wrong bits, and
TestRaveledHaarPass pins both that raise and the downcoef/dwt equivalence a
pywt upgrade could take away.
Drops the block constructor knob: the fold chains are written for 4, nothing
ever passed another value, and a knob that silently decodes wrong is worse
than no knob.
Peak RSS 111 MB to 21 MB on a 4.3 MP image; the decoder itself 0.011s to
0.007s, which is only 0.4% of identify() now that it is under 2% of the run.
Output bits and detector verdicts over 200 sampled data/ images, two
synthesized carriers and eight degenerate shapes are byte-identical to the
pre-vectorization decoder.

Output stays bit-identical: decoder bits and detector verdicts recorded over
200 sampled data/ images plus two synthesized carriers before and after, and
the record is byte-identical.
Measured on a 1536x2816 image -- decoder 0.280s to 0.016s, warm identify()
1.757s to 1.365s with both arms timed in one process.

Renaming it strands every pip install and every pinned dependency on it,
including the ComfyUI node package, and the console script has the same
property since users have it on PATH. Recorded at the name itself, where
whoever considers changing it will be looking.

These directories are empty today, so git shows nothing and the gap is
invisible. The moment the sync writes into one, a routine running
git add -A commits another harness's generated config, and the harness
audit then fails after the fact rather than before it. Paths are the
canonical untrackedConsumerPaths list, anchored to the repo root so a
same-named source file deeper in the tree is not caught.

The probe shipped with no tests while every sibling research script has them,
and it needs neither a model nor a GPU, so nothing justified the gap. Its whole
output is a ranking and a mispaired comparison still prints a plausible number,
so the pairing tests carry more weight than the metric ones.
The centerpiece builds a correctly phased and a wrong-phased delivery of the
same clip. Both have six frames, so the frame-count check the probe used to rely
on passes for both; the misaligned one scores near 9 dB against 40+. A separate
assertion pins that the probe binds the engine's sampler rather than a copy,
which is the contract a same-phase private copy would otherwise satisfy
silently. This file now holds the only constraint on that sampler's phase.
CI ran none of this. The test matrix installs no ffmpeg, and the job that does
install it ran one class from another file, so five of these tests would have
skipped on every runner. The video-e2e job now collects this file too.
Recorded in .claude/rules/development.md: mutating the sampler's >= to > proves
nothing, because the 1e-9 epsilon makes both branches agree on exact equality.
The phase or the period is what has to move. That inert mutation passed a green
suite here before the real one failed five tests.
Dropped the downscale test's PSNR bound: solid colors survive both the downscale
and the upscale exactly, so any score there pins the local ffmpeg's chroma
rounding rather than the probe. Geometry is the assertion that means something.
