v1.0.41

2K Image Watermark Removal

• Recognize the new Gemini 2K watermark layout found on exact 2048x2048 and 2400x1792 outputs: a 48x48 watermark with 96px right and bottom margins.
• Keep existing canonical candidates first for other image sizes, and require candidate validation before selecting the new secondary layout.
• Preserve best-effort processing without adding a rejection threshold, changing alpha strength, or enabling broader cleanup behavior.

Release Validation

• Reprocessed all 12 public issue #101 samples: all 12 were processed, 11 passed the residual gate, and every sample selected the reported anchor. One sample retains a mild edge residual instead of being skipped.
• Added deterministic regressions for both confirmed 2K dimensions and a negative control for the existing 2752x1536 canonical 96x96 layout.
• Complete automated result: 1,677 passed, 32 skipped, and 0 failed.
• Packed SDK consumer smoke: 8 passed.
• Scoped image quality gate, release goal audit, and GitHub CI passed.

v1.0.40

Watermark Candidate Selection

• Keep best-effort processing when a weak exact 96px / 192px-margin rescue competes with the canonical 96px / 64px-margin Gemini candidate, and prefer the candidate with stronger positive source evidence.
• Fix the wrong-location removal reported in issue #142 without adding a rejection threshold that could leave a visible watermark unchanged.
• Preserve the established exact-R192 path for samples with stronger confirmed 192px-margin evidence.

Release Validation

• Fix the image release gate so already published video changes are not attributed to the current image release.
• Resolve the previous package release from Git history while preserving the explicit base-tag override and the out-of-scope video-change blocker.
• Complete automated result: 1,673 passed, 32 skipped, and 0 failed.
• Packed SDK consumer smoke: 8 passed.

v1.0.39

Animated video watermark tracks

• Detect and retain independent compact 24x24 / 48px-margin and relocated 48x48 / 96px-margin watermark tracks when Gemini alternates geometry during one video.
• Select the active track per frame instead of applying one global candidate to the complete export.
• Isolate alpha, temporal, and AI reuse state per track so animation phases do not contaminate each other.

Verification

• Production build passed.
• Complete test suite: 1,671 passed, 32 skipped, 0 failed.
• Issue #136 source: 240/240 frames exported and all 469 AAC packets retained.
• npm: @pilio/gemini-watermark-remover@1.0.39.

Fixes #136 via #140.

This is a package/SDK and website-video-path release. The Chrome extension/userscript version is unchanged.

v1.0.38 (package/SDK)

Package / SDK release

Highlights

• Video progress now estimates the complete export from duration and sampled frame rate instead of treating the capped metadata probe as the total.
• --video-timeout-ms is now an inactivity timeout: active long-running exports can exceed it, while genuine stalls still fail with progress context.
• The CLI reports throttled phase, percentage, frame count, and AI reuse progress; adds --video-bitrate-mbps; and publishes the progress callback contract in TypeScript declarations.

Verification

• Production build passed.
• SDK smoke suite: 8 passed, 0 failed.
• Complete serial suite: 1,698 total; 1,666 passed; 32 skipped; 0 failed.
• Pull-request CI and post-merge main CI passed.
• A real 240-frame video completed in 61.9 seconds with a 60-second inactivity timeout because frames continued advancing; a 100 ms no-progress interval failed as expected.
• Tarball SHA-256: 4e15ae8802047cc60ac8ccfa03b6cac6d683f44b23174f0f0d3a79fc65384237.

Based on the original implementation and tests contributed by @shantz1 in #110, completed through #135 and #137.

This is a package/SDK-only release. It does not contain a new userscript or Chrome extension artifact. The website is a separate deployment surface.

v1.0.37 (package/SDK)

Package/SDK release

This release updates @pilio/gemini-watermark-remover with the issue #101 residual-removal improvement from PR #133.

Watermark removal

• Restores full-strength alpha removal for positively signed exact 96px/R192 20260520 watermarks.
• Prefers the full-strength candidate when localized positive source evidence is stronger than circular self-template ranking.
• Preserves the issue #123 inverse-polarity guard so unsupported dark-polarity inputs remain conservative instead of risking a black-hole artifact.

Across the six latest issue #101 reporter samples, five positive-source samples selected full-strength alpha and were visually clean in review. The inverse-polarity sample remained conservatively limited.

Verification

• Full serial suite: 1685 total, 1653 passed, 32 skipped, 0 failed.
• SDK package smoke: 8 passed, 0 failed.
• Production build, pull-request CI, and post-merge main CI passed.
• Package tarball SHA-256: 049f1df67a36a4ddb142ac28fe8d8743a6c4422232d900d4cf9f84d4426b22d0.

Release scope

This is a package/SDK-only release. It does not publish new userscript or Chrome extension artifacts; those browser release surfaces remain at v1.0.35. The public website is a separate deployment surface and must be upgraded to this SDK version independently.

v1.0.36 (package/SDK)

Package/SDK-only patch release for the video processing fixes in #131.

Highlights:

• Projected video watermarks smaller than 40px now use the V1 alpha family, improving the reported 848x478 / 32px case in #119 while preserving the existing selection path for larger marks.
• Explicit SDK adaptiveAlpha: true choices now survive the video page's automatic export preset.

Verification:

• Full serial suite: 1,648 passed, 33 skipped, 0 failed.
• SDK package smoke: 8/8 passed.
• Registered real-video regression suite: 5/5 passed.
• #119 fixed-anchor residual: 0.3795 -> 0.0366 (90.4% reduction, pass).
• npm tarball SHA-256: 8767fe4b63dcc5157f3628fc40ab25266995cf7dfd11b41dd8035484f60c58b4.

Release scope:

• Publishes @pilio/gemini-watermark-remover@1.0.36 for SDK and downstream website Worker consumers.
• Does not publish a new userscript or Chrome extension. The latest browser artifacts remain v1.0.35.
• Does not claim broad video alpha-shape, denoise, or Allenk parity improvements beyond the verified #119 fix.

v1.0.35

Watermark removal safety

• Prevents the exact 96px/R192 white source-witness rescue from accepting inverted or effectively zero signed spatial evidence solely because unsigned edges are strongly localized.
• Avoids the visible black-hole damage reproduced from issue #123 on structured dark content.
• Keeps the existing dark-polarity exception narrowly gated behind an independently selected drifted dark-polarity trial and strong localized signed spatial evidence.

On the reported #123 image, v1.0.35 preserves the source pixels and reports no-watermark-detected instead of producing damaged output. This is a damage-prevention hotfix; it does not claim reliable removal for that watermark family, and #123 remains open for additional samples.

Verification

• 1679 tests: 1647 passed, 32 skipped, 0 failed in the versioned image release validation.
• SDK package smoke: 8 passed, 0 failed.
• Production build, extension packaging, image-quality gate, scoped release readiness, and release goal audit passed.
• Pull-request CI and post-merge main CI passed.

v1.0.34

Watermark removal

• Adds evidence-gated handling for difficult Gemini 96px watermarks at the 192px right/bottom anchor, including low-confidence cases that were previously returned unchanged.
• Prefers a conservative exact-anchor result when a shifted candidate would damage nearby text or artwork.
• Keeps visible-residual and uncertainty metadata for imperfect best-effort outputs; variable contour residuals remain under investigation in #120.

Verification and tooling

• Adds pnpm issue:verify -- --issue <number> for repeatable issue sample verification with Release asset digest checks and reviewable reports.
• Tightens diagnostic alpha-profile admission so visibly dirty candidates cannot be promoted based only on relative score improvement.
• Revalidates the 14 public #120 samples with 14/14 watermark detection, 3/14 strict end-to-end quality passes, and no admitted production alpha-profile candidate.

This release improves processing coverage and content safety. It does not close #120 or claim that all visible contour residuals are removed.

v1.0.33

CLI packaging compatibility release. Expanded the optional sharp peer range to include tested 0.35.x releases; no watermark algorithm behavior changed. Verified sharp 0.34.5 and 0.35.3 produce byte-identical output on the same 2816x1536 Gemini fixture. SDK smoke: 8 passed. Full suite: 1536 passed, 32 skipped, 0 failed. Extension SHA-256: 40d26f5cbef5afd5a07f362f51230bf18b0ecb174da61811ac4bbcac55a0b4a7. npm tarball SHA-256: 34039618353271a84f1a778abc4aa830ceb69ea021829a4ae44f868c7ef914b3.

v1.0.32

Watermark removal

• Expanded evidence-gated handling for recent 48px and 96px Gemini watermark variants, including dark-polarity marks, non-standard anchors, and difficult low-texture backgrounds.
• Added bounded local alpha-gain search and a dedicated large-margin 48px rescue to reduce visible halos without changing validated anchors.
• Improved best-effort candidate discovery while retaining explicit uncertainty metadata and conservative content-protection gates.

Quality and page integration

• Evaluated final post-repair pixels with polarity-aware clipping, halo, texture, and residual-localization signals.
• Added final-state decision-path metadata and broader real-sample quality diagnostics.
• Prevented zero-sized or stale Gemini image nodes from blocking later renderable images in the serial preview queue.
• Verified the current real-page preview, clipboard PNG, and native full-size download paths in the fixed Chrome profile.

Verification

• Full automated suite: 1,568 tests, 1,536 passed, 32 skipped, 0 failed.
• GitHub Actions passed on the release commit.
• Image-scoped release quality gate and release goal audit passed.
• Extension package SHA-256: 8687386fa5b91ba75c2c48d01a9a939f80e467dbd3d113641a066179c0f01396.

Remaining difficult residual, missed-detection, and content-damage cases continue to use best-effort handling. This image-scoped release does not claim Allenk video parity.
