OpenArt.ai stamps free-plan generations with a semi-transparent white "OpenArt" wordmark (bowtie/infinity icon + brand name) placed near the CENTER of the frame rather than in a corner. Confirmed from a customer- reported raiw-app production case where the mark went completely undetected and unremoved, with no C2PA/EXIF/TC260 signal for identify to fall back on. - Add a new "cc" (frame-center) corner mode to the shared TextMarkConfig/TextMarkEngine base, alongside the existing corner/edge anchors. - Add openart_engine.py, following the existing text-mark engine pattern. No real capture exists (OpenArt requires an account, out of scope to create), so the bundled alpha asset is a procedural reconstruction of the public logo and the NCC threshold is an explicitly-labeled provisional guess, not a measured calibration. - Register the mark in watermark_registry.py, which auto-derives identify's platform attribution. - Add tests/test_openart_engine.py (synthetic composites only) plus registry/identify test coverage, and document the mark and its calibration caveats in README.md, docs/supported-signals.md, docs/module-internals.md, and the skill's commands.md.

Maintainer scripts
These scripts are development and evaluation tools, not installed CLI commands. Run
them from the repository root with uv run python scripts/<name>.py --help. Inputs
under .local-eval/ and generated reports remain untracked unless a data README
explicitly names a tracked canonical result.
Audits and release checks
| Script | Purpose |
|---|---|
corpus_gap_scan.py |

visible_removal_audit.py |
Audit visible-removal results over a local corpus. |
watermark_benchmark.py |
Run hash-pinned image cases while keeping detection, removal observation, and fidelity separate. |
watermark_benchmark_report.py |
Aggregate repeated benchmark results with artifact-aware counts and separate cold/warm timing. |
watermark_benchmark_resources.py |
Measure fresh-process wall time and absolute peak RSS for benchmark manifests. |
Calibration and corpus preparation

|---|---|
contentseal_transforms.py |
Reproduce and hash-check deterministic Content Seal variants. |
detector_response.py |
Measure detector response over mark size, contrast, background, and aspect. |
fill_quality.py |
Measure visible-fill quality against constructed ground truth. |
ladder_headroom.py |
Measure recall cost from the coarse scale ladder. |
registered_mark_calibrate.py |
Measure a registered detector without conflating visual positives, metadata cohorts, adjudicated negatives, and unlabeled controls. |

visible_recall_sample.py |
Build an unbiased blinded sample for recall measurement. |
visible_sheets.py |
Build blinded contact sheets for relaxation candidates. |
watermark_benchmark_cohort.py |
Build the deterministic synthetic DWT-DCT and TrustMark cohort consumed by watermark_benchmark.py. |
spectral_pipeline_probe.py |
Measure a prompt-grouped, phase-free spectral source-pipeline hypothesis without presenting it as SynthID detection. |
source_pipeline_classifier.py |
Train or run an abstaining OpenAI/Google/unknown source-export classifier; research-only and not SynthID detection. |
watermark_benchmark_real_cohort.py |
Build a publication-cleared, provider-paired and content-stratified real-image cohort. |
retrain_photo_classify.py |
CPU-retrain the 2026-08-31 photo heads from a sha256-keyed cache pack, no images. |
publish_photo_classify_hf.py |
Upload the photo-classify card and freeze weights to Hugging Face wiltodelta/raiw-photo-classify. Manual; the Action publish-photo-classify-hf.yml is the write-token path. |
publish_source_classify_hf.py |
Upload the derivative source-pipeline model and its public card to Hugging Face wiltodelta/raiw-source-classify. Manual; the Action publish-source-classify-hf.yml is the write-token path. |

Research and diagnostic prototypes
| Script | Purpose |
|---|---|
cjk_tail_probe.py |
Test a generic template for otherwise uncovered CJK labels. |

Sweep the historical ControlNet removal prototype. |
analyze_engine_selection_study.py |

Generated assets
| Script | Purpose |
|---|---|
render_pill_silhouette.py |
Render the synthetic Jimeng pill silhouette. |
render_vendor_silhouettes.py |

sync_c2pa_soft_bindings.py |
Validate the official C2PA soft-binding registry and refresh its pinned runtime snapshot. |
maintain.sh and the CI lint job run sync_c2pa_soft_bindings.py --check, so an
upstream registry change fails with the refresh command instead of silently
leaving new algorithms unnamed. The check and runtime parser are read-only;
running the sync command without --check is the explicit snapshot update.
Shared helpers
_plain_console.py provides plain-text fallbacks for Rich output, and
_text_eval.py contains normalization helpers shared by text-evaluation scripts.
hf_publish.py owns the common authenticated, allowlisted Hugging Face model
repository upload used by the two model publishers.
engine_selection_manifest.py owns the content-matrix schema and validation
shared by its integrity check and the real-image benchmark builder.
