Extend [tool.ruff].lint.select with PLW and S (bandit) to match the upstream reference repository, ignoring S101 (asserts are idiomatic in the test suite) and S603 (subprocess argv is shell-free by construction). Apply mechanical fixes for the fallout: explicit check=False on test subprocess.run calls, targeted noqa comments on deliberate randomness, try/except-pass, urlopen, xml-parse, and global-state sites, and a loop-variable rename in configuration.py. Also carries the pyproject.toml release metadata that mechanical changes depend on: version 0.3.0 -> 0.4.0, console scripts wm-serve / wm-audit-dir / wm-audit-site, and setuptools package-data so the wheel ships SKILL.md, references, pinned requirements, and setup scripts. Behavior-neutral: no runtime code paths change.
Port the optional-backend target surface from the upstream reference, adapted to our repo-root Docker layout and naming: - serve: run the HTTP service locally (stdlib only) - smoke-/bootstrap-/docker-*-build/-help for ctrlregen, markllm, and markdiffusion backends, matching the existing synthid targets - docker-core-build/-help for the core service image (wm-serve entry) - compose-up / compose-up-heavy / compose-check - install-cursor-text-skill (install_skill.py) - format (check-only alias, upstream semantics) and lint-fix check/compile/demo and the synthid targets are unchanged.
- requirements-test.txt: add openapi-spec-validator==0.9.0 used by the CI OpenAPI validation step - .dockerignore: switch to deny-by-default allowlist (skills/ + pyproject.toml only) so tests, research reference checkout, venvs, and tooling never enter an image build context - .gitignore: ignore .env and Hugging Face cache dirs used by the optional heavy backends
…ackends Port the external-checkout bootstrap surface for the optional heavy backends; nothing upstream is vendored, and every checkout is pinned to a commit SHA with a post-clone rev-parse assertion (re-pinning existing checkouts that drifted). - setup_ctrlregen.sh/.ps1: pinned noai-watermark commit, sparse /src/ checkout, CUDA-aware torch index; the Windows port probes published torch indices and verifies the final torch has CUDA + the card's compute capability - setup_markllm.sh: pinned THU-BPM/MarkLLM commit, sparse checkout, minimal harness dependencies - setup_markdiffusion.sh: PyPI markdiffusion==1.0.2 default plus --checkout mode at a pinned commit, torch>=2.4,<2.11 - setup_synthid.sh: pin b1108367 + rev-parse verification and pinned pip (was tracking main with unpinned pip); new Windows port - requirements-synthid-scorer.txt: exact pins (numpy 2.5.2, scipy 1.18.0, opencv 5.0.0.93, PyWavelets 1.9.0, scikit-learn 1.9.0, Pillow 12.3.0) replacing unpinned ranges - requirements-ctrlregen/markllm/markdiffusion.txt: exact pins with the upstream-compatibility notes kept in the headers The final heredocs reference instead of the upstream's escaped placeholder, so the printed instructions run as-is.
Core image (repo-root Dockerfile): - digest-pinned python:3.14-slim base - exiftool, qpdf, and c2patool (v0.27.15, sha256-verified) baked in - pip installs the package, so wm / wm-serve / wm-audit-dir / wm-audit-site are on PATH; CMD runs wm-serve on 0.0.0.0 - pinned pip, unprivileged uid 10001 runtime user, PYTHONUNBUFFERED compose.yaml: wr-core (loopback-mapped 127.0.0.1:8765, read-only rootfs, tmpfs /tmp, bearer-key passthrough) plus harness profile (wr-markllm, wr-markdiffusion one-shot CLIs) and heavy profile (wr-ctrlregen, wr-synthid, wr-synthid-score sidecar). ctrlregen and synthid images are local-only tags: their upstreams are not publicly redistributable, so they are never pushed to GHCR. compose-check.sh: /health probe for wr-core plus --help exit-code checks for each one-shot service.
…arkdiffusion Shared hardening across all four: digest-pinned slim bases, pinned upstream commit + rev-parse assertion (where a checkout is involved), pinned pip, unprivileged uid 10001 users, PYTHONUNBUFFERED. - Dockerfile.synthid: upgraded to 3.14-slim digest, pinned reverse-SynthID commit b1108367 with rev-parse assert, copies synthid_score_server.py, exact-pinned scorer requirements - Dockerfile.ctrlregen: 3.11-slim (research-era ML pins have no 3.14 wheels), pinned noai-watermark commit, CPU torch first then pinned ML deps, local-only image (no upstream LICENSE) - Dockerfile.markdiffusion: 3.14-slim, PyPI markdiffusion==1.0.2, torch from the CPU index, publishable - Dockerfile.markllm: 3.14-slim, pinned THU-BPM/MarkLLM commit with rev-parse assert, torch>=2.13,<2.14 from the CPU index, publishable All four use the repo-root build context governed by the new deny-by-default .dockerignore.
…ew, release images ci.yml: - matrix keeps ubuntu 3.10/3.12/3.14 and adds windows-latest x 3.12 - OpenAPI contract validation against wm-serve's generated spec via module call (no live server) - make check and pip-audit run once on the ubuntu 3.14 leg - Windows leg runs a pwsh smoke (clean_text/rewrite_text/clean_file) and parses setup_ctrlregen.ps1 / setup_synthid.ps1 with the PowerShell parser, asserting the post-install CUDA verification line - all actions SHA-pinned; permissions: contents: read; ci-green gate job retained for branch protection New workflows: - codeql.yml (python, weekly + push/PR, SHA-pinned) - dependency-review.yml (fail-on-severity: high, SHA-pinned v5.0.0) - release-images.yml: on v* tags, builds and publishes the core, markllm, and markdiffusion images to ghcr.io/pythoughts-labs with SBOM + provenance attestations; ctrlregen/synthid intentionally excluded (non-redistributable upstreams) - dependabot.yml: github-actions weekly, root pip weekly, scripts pip weekly (human-verification warning for backend pins), docker monthly - PULL_REQUEST_TEMPLATE.md and CODEOWNERS extension
New standalone skill tree for rewriting + Unicode-hygiene passes on prose the user owns: SKILL.md (rewrite-then-deterministic workflow, protected-span rules, Verifiable/Best-effort/Not-established taxonomy), references/watermark-notes.md and responsible-use.md, and a vendored scripts/ directory. The vendored scripts/text_unicode.py is byte-identical to the engine in skills/remove-ai-marks/scripts/. This duplication is deliberate: the skill is a portable artifact installed into ~/.cursor/skills by install_skill.py and must run without the repository checkout, so it cannot import the canonical copy. The byte-identity test enforces that the two copies stay in lockstep. Also ships: - install_skill.py / install-skill.sh: staged tempdir copy into ~/.cursor/skills (--cursor-home / CURSOR_HOME override), refuse existing without --force, --force creates a .backup.<12hex> and rolls back on failure - integrations/cursor/clean-user-facing-text.mdc: alwaysApply Cursor rule with the ethics guardrails
…tity guard Seven tests covering the standalone skill: clean_text CLI via stdin, placeholder-free SKILL.md, installer default/no-force/force-backup behavior, byte-identity of the vendored text_unicode.py against the main engine, and the bidi/emoji-glue drift regressions.
…tart guide - references/service-mode.md: the HTTP thin-client pattern (health -> capabilities -> /inspect -> /clean curl flow, detect_before/after, audit CLIs, exit codes, limitations), adapted from the upstream skill and aligned with our wm-serve / compose / GHCR naming - references/markdiffusion.md: upstream MarkDiffusion reference with the SCRIPTS path adjusted to skills/remove-ai-marks/scripts - docs/windows-autostart.md: scheduled-task + VBS launcher for the service at login, with our repo URL and script path
Format tables now list WebP, BMP, GIF, TIFF/BigTIFF, XLSX, PPTX, and EPUB; the PDF chain documents the new qpdf step; DOCX customXml is described as dropped-with-pruning (the previous docs still said it was preserved, which phase 5 changed). New README sections: text watermark detection and stylometry, audit suite (JSON/human/SARIF), HTTP service + compose quick start, heavy backends with license posture, and a 'What's new in 0.4.0' entry. Coverage-and-limits reflects the shipped best-effort pixel removal options. DESIGN roadmap and invariants updated (confidence levels, SARIF rules, shipped-since-0.4.0 list); SKILL.md classification table and hard limits match the implementation. .env.example fixes MARKLLM_DIR to the bare upstream-pointer convention the code reads.
📝 WalkthroughWalkthroughThe change adds version 0.4.0 capabilities across format processing, Unicode cleanup, auditing, HTTP services, watermark detectors, optional ML harnesses, Docker deployment, CI, packaging, and documentation. It also adds broad regression coverage for the new workflows. ChangesWatermark Remover 0.4.0

0.4.0 release candidate — complete port + release hardening
Finishes the upstream port (phases 11–15) and prepares the repository as a controlled 0.4.0 release candidate. Feature scope is frozen; nothing here is exploratory cleanup.

v0.4.0→ release-images workflow publishes core/markllm/markdiffusion to GHCR with SBOM + provenance attestations (verify withgh attestation verify). CtrlRegen/SynthID images stay local-only by license. PyPI (if ever) should use Trusted Publishing.Deliberate design decision to review
skills/clean-user-facing-text/scripts/text_unicode.pyis a byte-identical copy of the main engine, enforced by a test. It is intentional: the skill is installed into~/.cursor/skillsand must run without the repo checkout, so it cannot import the canonical module. The sync test prevents drift.Summary by CodeRabbit
