 Every single-image command declares `source` with `dir_okay=False`; `batch` declares its directory with `file_okay=False`. Keep `tests/test_cli_robustness.py::TestDirectoryInputIsRejected` as the regression guard.

Keep [`../../skills/remove-ai-watermarks/`](../../skills/remove-ai-watermarks/) in the same change when command routing, extras, exit codes, mark keys, or the intended-use boundary move.
+
+`tests/test_agent_skill.py` enforces that by comparing the skill's prose against the live Click tree. Guard the SET, not the instances: per-flag comparisons only check what the skill already documents, so `--vendor`, `--pipeline auto` and then the whole `classify` and `verify-openai-synthid` commands each shipped with a green suite. `test_every_cli_command_is_named_somewhere_in_the_skill` closes that; raise `MIN_CLI_VERSION` in the skill's probe whenever a reference names a command, flag or value the previous release lacked, or the probe tells an agent its CLI is current right before it types something that build rejects.

+Provider verification services and provenance APIs are development-only oracles. Keep
+their SDKs in the development extra and their adapters out of the installed CLI,
+top-level Python API, and runtime detection/removal pipelines.

 Do not add an option whose only outcome is an error. Model id, step count and CFG are fixed by the profile, so none of them is a parameter of the CLI, `InvisibleEngine`, or `WatermarkRemover` -- they were accepted-then-rejected for a while, which moved the failure several frames below the caller and advertised choices the pinned stack cannot honor. If a value cannot vary, delete the knob rather than validating it.

-`device` is the deliberate exception and stays a library parameter: `None`/`"auto"` detect, `"cuda"` pins without detecting, and everything else raises at construction. It is not a CLI option, because the only value a user could usefully type is the one auto-detection already finds.
+`device` is the deliberate exception and stays a library parameter: `None`/`"auto"` detect, `"cuda"` pins without detecting, and everything else raises at construction. On the image path it is not a CLI option, because the only value a user could usefully type is the one auto-detection already finds. The video SynthID commands (`video invisible`, `video all`, `video batch`) do expose `--device`, whose VAE runs on cuda, mps, or cpu, so a user can usefully pick one. `test_device_exists_exactly_where_the_skill_says_it_does` pins that split; do not read this paragraph as licence to delete the video flag.

 The same rule applies to install hints: name the extra that actually makes the command work (`qwen-zimage`, not `diffusion`), and keep the printed command shell-quoted -- bare `pkg[extra]` is a glob in zsh.

 From a worktree, `uv run` imports the package from the MAIN checkout -- that is where the editable install points. A script measuring a worktree's edit must insert that worktree's `src` at `sys.path[0]` and assert `module.__file__` resolves inside it, or it silently compares unmodified code against itself.

+Every registered mark carries a committed example: `data/fixtures/visible/<key>/example.png`
+(image marks) and `example.mp4` (video marks), regenerated by
+`scripts/render_visible_examples.py`. `tests/test_visible_examples.py` is the canary: it
+fails when a mark is registered without an example and when an engine stops detecting its
+own example. The examples are deterministic synthetic composites of the committed
+silhouettes. When the generator fails after a geometry or gate change, fix the generator
+(and the engine) together; do not hand-edit the binaries.

+Visible-mark content must distinguish the registry key, the provider's canonical
+product name, and the literal text rendered in the mark whenever those differ. Verify
+external provider names against the provider's official source rather than inferring
+them from an asset filename or OCR text.

+# Engine-selection fixture set
+
+This directory is the tracked, content-balanced input set for researching a
+deterministic `auto` engine choice. It is not a training corpus and it is not a
+watermark-oracle corpus.
+
+## Content matrix
+
+`content-manifest.csv` contains 19 prompt-matched pairs. Each pair uses the
+same prompt and generation index across OpenAI `gpt-image-1-mini` and Meta
+`muse-image-1.0`, covering the content classes that materially stress image
+regeneration:
+
+- natural and urban scenes;
+- single-person portraits and people in context;
+- animals, food, products, interiors, architecture, macro detail, and action;
+- flat, isometric, watercolor, and surreal illustration styles.
+
+The files are exact copies of generation outputs collected for the
+`docs/arxiv-paper-review` research branch. The manifest records the SHA-256 of
+the committed bytes. The old OpenAI collection manifest stored the API payload
+hash under `sha256`; `source_payload_sha256` preserves that value while
+`sha256` always means the actual file bytes here. Meta's two hashes are the
+same.
+
+The project maintainer has cleared these exact committed outputs for permanent
+public test and benchmark reuse. `reuse_basis` records that clearance on every
+row. It is permission for this fixed fixture set, not a claim that either
+provider grants a general-purpose dataset license for arbitrary generations.
+
+One generation per prompt and provider is enough for the first paired
+discovery pass. Any policy inferred from it must be challenged against unused
+generation indices from the local research archive before shipping. Generated
+outputs belong outside this directory.
+
+`carrier-manifest.csv` adds the canonical, already tracked signal carriers to
+the study without copying their bytes. Together the two manifests cover
+ordinary content, text, single faces, face grids, and mixed face/text scenes.
+
+## Signal carriers
+
+The content matrix was re-encoded by its collection pipeline and has no local
+provenance signal. It must not be used to set or certify watermark-removal
+strengths. The tracked oracle/carrier inputs remain in their canonical homes:
+
+- OpenAI and Google SynthID: `data/synthid/originals/` with
+  `data/synthid/manifest.csv`;
+- Meta Content Seal: `data/contentseal/originals/` with
+  `data/contentseal/manifest.csv`.
+
+There is no tracked, publication-cleared Microsoft InvisMark carrier yet. The
+three Paint sources used by the earlier calibration are user uploads and remain
+outside git. A Microsoft row may be added only from a newly generated or
+otherwise publication-cleared source, with a pixel-identical metadata-stripped
+control that remains positive in Microsoft's detector.
+
+## Integrity check
+
+Run:
+
+```bash
+uv run python scripts/verify_engine_selection_fixtures.py
+```
+
+The check validates paths, byte hashes, dimensions, prompt pairing, and the
+declared provider/content matrix without loading any ML model.

+# Visible-mark example gallery
+
+One committed example per registered visible mark, so the repository carries a
+working sample of everything it supports. `tests/test_visible_examples.py` holds
+both sides to it: a mark registered without an example fails the suite, and so
+does an engine that stops detecting its own example.
+
+## What these files are
+
+Every example is SYNTHETIC: `scripts/render_visible_examples.py` composites the
+mark's committed alpha or silhouette onto a deterministic generated base photo at
+the engine's measured geometry. Controlled provider captures were used to solve
+some alpha assets, including Samsung's measured opacity; the remaining shapes are
+repository-owned renders rather than copied vendor rasters.
+
+The examples demonstrate DETECTION geometry and house style, not vendor raster
+fidelity; real-world variants (fonts, opacities, sizes) are covered by the
+engines' recorded calibration evidence.
+
+The Qwen, Kling, Yuanbao, Baidu, Jimeng, LiblibAI, Microsoft, Sora, Hailuo, and Veo
+directories additionally contain real provider-marked sources. These files
+retain the source bytes and names used here are deliberately distinct from the
+generated canonical examples. The current LiblibAI output is evidence of a
+provider format change, not a positive example for the registered historical
+wordmark detector:

+vase, soft natural daylight, plain uncluttered background, no text, no logos.`
+It carries the current lower-right `KlingAI 3.0` mark and a TC260 AIGC field
+whose producer code `001191110108335469089C10100` normalizes to Kuaishou's
+registered USCC. The maintainer generated and explicitly cleared the output for
+this noncommercial deterministic computer-vision regression fixture. The same
+Kling terms and retained-brand restriction listed for the video apply; the file
+is not offered under the repository license.
+
+The Yuanbao image is the original 1776 x 1328 RGB PNG returned by an
+authenticated AI Image conversation. It was generated at no charge from the
+neutral prompt `A documentary photograph of a blue ceramic mug on a plain
+light-gray studio table, soft even lighting, no text, no logos, no people.` It
+carries the visible lower-right two-line `元宝` / `AI生成` mark and a TC260 AIGC
+field naming Tencent's registered producer. The maintainer generated and
+explicitly cleared this output for use under the repository license.
+
+The Jimeng image is the byte-for-byte embedded JPEG extracted with
+`pdfimages` from page 29 of Zhonglun W&D's publicly distributed 2026 *Bank
+Finance Legal Newsletter*. It is a real Jimeng-generated debt-collection
+poster carrying both the top-left `AI生成` pill and the lower-right `即梦AI`
+wordmark. The repository retains one 705 x 705 image rather than the complete
+33-page publication, solely to test identification and removal of the two
+marks. Copyright remains with the source rights holders; this research fixture
+is not licensed under Apache-2.0. See

+The LiblibAI image is the original 2048 x 2048 RGBA PNG generated with Smart
+Image V2 for 18 introductory points from the same neutral prompt. It carries a
+top-left `AI生成` pill and a TC260 AIGC field whose producer code contains
+LiblibAI's registered USCC, but it does not carry the historical bottom-center
+`LiblibAI` wordmark that the registered `liblib` engine detects. This file
+therefore records the current provider behavior without falsely closing the
+historical positive-example gap. The maintainer generated and explicitly
+cleared the output for use under the repository license.

+The Veo file is the original 1280 x 720, 8-second MP4 downloaded from an
+authenticated Google Flow project. It was generated with Veo 3.1 Fast for 20
+Flow credits from the neutral prompt `A blue mug rotates on gray. Static camera.
+No people, text, logos, or audio.` after the account's `Visible watermarking`
+setting was enabled. It carries the fixed, low-contrast `Veo` text at the bottom
+right, valid Google C2PA, and an invisible SynthID marker. Google documents that
+Flow clips can be downloaded and shared, states that Google does not claim
+ownership of original generated content, and explicitly identifies SynthID in
+all Flow video output. The maintainer distributes this generated output under
+the repository license.

+## Regeneration
+
+    uv run python scripts/render_visible_examples.py
+
+The generator self-verifies: it fails (exit 1) if any registered mark does not
+detect on its own example, so regeneration is the fix point for drift.
+
+## Layout
+
+    <mark-key>/example.png   1536x2048..2048x2048 PNG, one per image mark
+    <mark-key>/provider-original.*
+                             Documented real provider-marked source where available
+    <mark-key>/example.mp4   960x540 90-frame clip, one per video mark
+                            (kling carries both: it is registered in both registries)
+
+Special cases: `gemini` composites the sparkle alpha map at the provider's
+configured position; `jimeng_pill` uses the measured 3:4 portrait geometry;
+`microsoft` is the opaque white pill with dark text
+holes (the discriminator its detector keys on). Video examples composite the
+detector's own synthetic template on every frame; where two marks share a
+shape family the example carries the discriminative variant (`veo` the legacy
+text form, `kling` the logo-plus-wordmark pair flush to the edge), because the
+temporal selection resolves cross-template ties by table order.
