`InvisibleOptions` promises in its docstring that every default mirrors
`InvisibleEngine`. Two fields made that promise cost something to keep: `force` is
not an engine parameter at all, and `controlnet_scale` was a third spelling of the
engine's `controlnet_conditioning_scale`. The mirror test carried an exception
table for each. This removes both, so the comparison needs no exceptions -- a field
that needs one is a field that belongs somewhere else.
`force` decides WHETHER the engine runs, which is settled before it is built, so it
joins `backend` and `sensitivity` as a parameter of `remove_all` and `remove_batch`
and is threaded to `_run_invisible` as its own argument. `controlnet_scale` takes
the engine's own name; the click option stays `--controlnet-scale` and is now
translated exactly once instead of at three forwarding sites.
Safe to do today: both symbols landed after 0.25.0 and have never been published.
The forwarding turned out to be the weaker half. A defaults comparison cannot see a
hardcoded literal at the seam, and `_run_invisible` passed the entire suite with
`controlnet_conditioning_scale` pinned to a constant. Each of the two knobs also
reaches the engine through TWO paths -- `remove_all` versus `remove_batch(mode="all")`
for `force`, `_run_invisible` versus `_batch_engine` for the scale -- and guarding one
left the other free to hardcode with a green suite. So:
* `test_every_field_arrives_at_the_engine_with_the_caller_s_value` drives the real
seam with all 13 fields set off their defaults; mutating any one of them to its
default fails it.
* `test_force_reaches_the_scrub_gate_in_every_scrubbing_mode` and
`test_batch_controlnet_scale_flows_to_the_cached_engine` are parametrized over
both modes, so neither path can be pinned alone.
Also fixes an order-dependent test surfaced by the added tests reshuffling the xdist
shards. `test_visible_path_decodes_file_once` counted every `image_io.imread` in the
process, but the Gemini engine loads its own bundled capture assets on first
construction, so the count was 3 on a cold engine and 1 on a warm one and the test
passed only when an earlier test happened to build the engine first. It now counts
decodes of the SOURCE, which is the invariant it exists for, and still fails when the
shared decode is broken. The production path was never wrong: the source bitmap is
decoded exactly once.

Every code-referencing claim in the docs, the README and the rules files was
checked against src/, and each finding was re-derived independently before it
was applied. 35 held, 5 were false positives.
Two of them were code, not text. `InvisibleOptions` promises in its docstring to
mirror `InvisibleEngine`, and two defaults had silently stopped:
`max_resolution=None` reached `_target_size`'s `max_resolution > 0` and raised
`TypeError` on every library call that left the options alone, and
`cpu_offload=True` made a library run slower than the identical CLI run. Both are
fixed, and `TestInvisibleOptionsMirrorTheEngine` compares the two signatures
field by field rather than pinning the two values that happen to be known. A
companion assertion in `TestTargetSize` reads the engine's own declared default,
so a drift on the engine side -- which the mirror check alone would accept,
because both sides would still agree -- fails too.
The user-facing docs: README called `invisible` GPU-optional where it raises
without CUDA, and gave the image `metadata` command `video metadata`'s output
rule, promising the source survives a command that overwrites it. Yuanbao was
missing from the supported-mark list. `veo` was listed among the video policies
that require a run anchor, though its row sets no `anchor_iou`.
`known-limitations` called ControlNet the default profile and contradicted
itself ninety lines below. An unescaped pipe truncated the `hailuo` table row.
The `dev` extra, the CI shape, ffmpeg's role, the sdist boundary and the
strength-curve range were corrected, and `remove_all`/`remove_batch`, the pill
gate, `erase --keep-metadata` and `all`'s CUDA failure mode were documented.
Research notes that described removed modules, extras and flags in the present
tense now say so once in the page banner instead of sentence by sentence, which
covers the whole page rather than the lines that happened to be noticed, and one
fixture is referred to by role rather than by name.

The visible-mark path had grown three copies of one ladder sweep, four
near-identical `detect` arms, and four hand-rolled `footprint_mask` overrides;
mark knowledge sat in five hand-maintained tables across three modules; and the
flagship `all`/`batch` pipeline existed only in cli.py, written twice with
divergent behavior.
Detection is now one measurement. `_ladder_best` replaces the three sweeps,
`_scan`/`_verdict` replace the four arms, and the winning box travels to the
mask on `TextMarkDetection.match_box` instead of being swept a second time.
`detect_both` returns the strict and relaxed verdicts from one scan, which
halves the arbiter's perception cost (260 -> 130 matchTemplate calls on a 2048²
image, verdicts identical field for field). A per-mark demotion goes in the new
`_post_gate` hook, never in a `detect` override -- an override is invisible to
the single-pass path, which is how the RunningHub and Yuanbao anchor gates
briefly stopped applying.
Everything about a mark is now one registry row: product, label regime, the
platform sentence `identify` reports, the metadata signals that confirm it, and
its TC260 producer codes. `identify._VISIBLE_MARK_PLATFORM`, the signal mapping
in `api.visible_provenance`, `_PRODUCT_OF` and the pill veto are derived from
those rows.
`api.remove_all` / `api.remove_batch` are the library form of the `all` and
`batch` commands; the CLI is a wrapper that owns console text and exit codes.
Progress is a `(stage, detail)` pair of stable tokens, so the CLI keys its
wording off structure rather than parsing the library's prose back.
Two intentional behavior changes, both verified against a recorded 811-image
sample of detector verdicts, removal-mask hashes, arbiter decisions and
`identify` reports:
* A TC260 label now relaxes the vendor its `ContentProducer` names rather than
ByteDance's pair on every China-AIGC image. 333 of 811 samples move; on 185
of them the previously relaxed pair was simply the wrong vendor, and the
mark actually present never reached the relaxed gate its own
`provenance_ncc_factor` was calibrated for.
* A confident LibLibAI detection suppresses the Jimeng pill, like every other
TC260 product's mark. It was registered alongside RunningHub and Baidu, both
of which were added to the hand-written veto list, and it was not. 1 sample
moves, and it is exactly the co-firing case.
Nothing else in that record changes: detector verdicts, mask hashes and
`identify` verdicts are byte-identical, and all 200 calibration constants are
untouched.
Also: `aigc_label` and friends plus `extract_c2pa_info` are memoized on
(path, mtime_ns, size) -- size because this package rewrites in place; the
native TC260 container readers route on magic bytes instead of the file
extension, so a mislabeled AVI or FLV is no longer invisible; `identify` shares
one pixel decode between the DWT-DCT and visible stages (TrustMark keeps its own
Pillow decode, which is not substitutable); and the six `stabilize_*` video
wrappers collapse into one policy table.

The Tier E adversarial sweep (new, scripts/robustness_suite.py) drove the real CLI
over truncated, corrupt, zero-byte, absurdly-shaped and bomb inputs, unicode and
RTL paths, hostile output directories and concurrent runs. It found two crashes;
the /simplify review then reproduced a third and worse one.
1. A FAILED WRITE CRASHED ON THE SIZE REPORT. image_io.imwrite is contractually
non-raising and returns False, but write_bgr_with_alpha discarded that bool and
returned None, so no caller could tell a failed write from a successful one.
Every write site then ran output.stat() to print the size, so a read-only
destination died with a bare FileNotFoundError pointing at the stat rather than
the write. The fix is deliberately NOT uniform: single-image commands exit via
the new cli._write_output_or_exit; api._write_visible_result RAISES so a library
caller gets an accurate error instead of a confusing FileNotFoundError from the
downstream metadata strip; and the batch sites raise but never SystemExit,
because the batch loop counts per-image exceptions and aborting would kill the
whole run.
2. BATCH LOST DATA SILENTLY. Into a read-only output directory it wrote ZERO files
for 2 inputs and exited 0 -- no traceback, no error, an empty output directory a
wrapping service would read as a completed run. The robustness harness could not
see this class at all, since it scored exit codes and traceback markers and this
failure has neither; it now asserts on the artifacts written.
3. A DIRECTORY PASSED AS THE IMAGE crashed the metadata scanner with
IsADirectoryError, because click.Path(exists=True) accepts directories. Fixed
with dir_okay=False on all six source arguments, so argument parsing refuses it.
Also adds Tier B4 (scripts/resource_ceilings.py): peak RSS per fill backend from
1 MP to 25 MP, one fresh process per cell. migan 603->775 MB and lama 4679->4779 MB
are flat in input size, confirming the crop-around-the-mask design and both
documented figures; cv2 is the only backend that grows (74->440 MB, 5.9x). The
harness's own no-op check originally allocated a full-frame temp before reading
peak RSS and inflated the numbers with input size -- it now compares only the mask
box, and the conclusion survived re-measurement.
And scripts/real_examples_e2e.py, which drives every command over real corpus
examples and checks the outcome rather than the exit code: 6/6 provenance classes
identified, 10/10 metadata strips re-scan clean, all three fill backends write,
diffusion on MPS writes genuinely changed images. It records samsung as a real
partial (the faintest mark, 0.431 -> 0.404 against a 0.40 gate on the weakest of
its 3 corpus positives) and treats the gated pill's refusal to act as correct.

Resolve 10 code-review findings on the v0.14.0 localize->fill path, several
release-blocking:
- gemini: build the removal mask from the decision's provenance-aware region
instead of a strict internal re-detect. A relaxed/assume_ai sparkle was
re-demoted by the FP gate into a None mask and reported removed while left in
the image; this also drops the redundant double-detect.
- registry: report a mark removed only when a fill actually happened (remove()
returns a None region for an empty mask), so a no-op is never claimed.
- api/cli: add write_noop so the CLI `visible` no-mark path writes nothing and
cannot clobber a pre-existing -o file (was write-then-unlink -> data loss);
create output.parent; skip the same-file copy (SameFileError on in-place).
- cli: catch the missing migan/lama backend RuntimeError on the visible/all
paths (matches `erase`); route the single-mark relaxation through the shared
resolve_relax instead of an inline copy.
- metadata: keep_standard=False no longer takes the AI-only lossless JPEG
short-circuit (it left standard metadata); defer a malformed-marker JPEG to
the PIL fallback instead of reporting a partial strip as complete.
- invisible: register the HEIF opener before Image.open (HEIC --force) and
RGB-convert before the PNG temp (CMYK JPEG).
- pill: normalize via to_bgr so a 4-channel BGRA array cannot crash cvtColor.
Regression tests for each; docs synced (resolve_relax, write_noop,
best_auto_mark -> detect_marks).

- Replace reverse-alpha removal with localize -> fill (template-free mask + one
shared cv2/MI-GAN/big-LaMa fill) for every mark; drops the colour-shift / dark-pit
failure modes, version-robust to a moved or re-rendered mark
- Separate perception/decision/action: engines report Candidates, a pure
decide(candidates, Context) arbiter owns all policy (sensitivity + provenance +
pill gate), remove_auto_marks orchestrates -- behavior-preserving (corpus 46/46/92)
- Three orthogonal knobs replace --method: --backend cv2|migan|lama,
--sensitivity auto|strict|assume-ai, provenance (auto from metadata)
- Add high-level api.remove_visible / visible_provenance (lazy top-level re-export);
visible --mark auto delegates to it so CLI and library share ONE path
- Read+write HEIC/AVIF on the pixel path via pillow-heif; imwrite preserves the input
format at max quality (JPEG q100/4:4:4); a no-op copies the original bytes verbatim
- Lossless byte-level JPEG metadata strip (no DCT re-encode); consolidate the two
remove_ai_metadata into one, delete legacy noai/cleaner + best_auto_mark
- Bump 0.13.0 -> 0.14.0
