v0.4.0 adds optional CtrlRegen pixel removal via an external backend, a finding-confidence taxonomy with aggregate audits, and a batch of Windows and false-positive fixes.

Optional CtrlRegen pixel removal (external backend)

  • Optional pixel-domain watermark removal via an external mertizci/noai-watermark checkout: clean_ctrlregen.py adapter + setup_ctrlregen.sh bootstrap (pinned commit, sparse checkout, venv, SHA verification), plus Dockerfile.ctrlregen and make bootstrap-ctrlregen / docker-ctrlregen-build / smoke-ctrlregen
  • clean_image.py --remove-pixel ctrlregen runs metadata strip → CtrlRegen removal → optional reverse-SynthID before/after score; inspect_image.py hints at the flag on a high SynthID score
  • Conservative default strength 0.25 (presets 0.15/0.25/0.35/0.5/0.7); the 512×512-native pipeline is auto-tiled by the backend for larger images; the torch subprocess gets higher env-overridable resource caps
  • Backend is never bundled: noai-watermark ships no LICENSE file (treated as all-rights-reserved), and its auto-install/restart code paths are bypassed by using CtrlRegenEngine directly

Finding confidence and aggregate audits

  • Findings are now classified confirmed / probable / informational / likely_false_positive, exposed in text/image/container JSON and human reports
  • New audit_dir.py (recursive tree) and audit_website.py (sitemap discovery + crawl) aggregate reports; documented in SKILL.md

False-positive fixes

  • DOCX: scan only docProps/customXml, not the visible body (#14)
  • Text Layer A: preserve emoji VS16/ZWJ after an emoji base; new --strip-emoji-glue paranoid flag (#22)
  • HTML: treat CMS generator tags as informational, not AI metadata (#13)
  • PDF: exclude stream payloads from the AI-marker byte scan (#13)
  • Inspect reports note unsupported/best-effort paths

Windows support

  • Gate POSIX-only preexec_fn and os.fchmod so writes and optional tools run on Windows (#15, #23)
  • Reconfigure stdio to UTF-8 so redirected Windows streams no longer raise on invisible Unicode; Windows CI leg + CLI smoke run (#23)

Docs and supply chain

  • README CtrlRegen section + research references (CtrlRegen, UnMarker, forensic-stealth caveat), responsible-use disclaimer; SKILL.md/matrix/vendor-notes/ethics updates
  • Dependabot config + security-path CODEOWNERS; bump scipy/numpy/opencv-python/scikit-learn/pywavelets and the base image to Python 3.14-slim
  • Mock-based CtrlRegen tests (no torch in CI)
