+# KJMix Pro 0.6.6 (build 17) — responsive imports and import history
+
+Verified on 4 November 2026.
+
+- File copying, fingerprints, archive extraction and metadata reading now run on a utility worker with its own SQLite connection. Imports show a progress dialog with current file, completed count, imported/skipped totals, cancellation and completion/error feedback. Completed tracks survive cancellation or errors.
+- Each source directory is indexed once per batch for companion CDG matching. Archive-to-track history mapping uses direct lookup; progress updates are throttled.
+- SQLite schema 10 adds persistent import history. Unchanged sources and archives are skipped on later imports. Audio fingerprints recognise renamed/copied tracks, preserving existing metadata and singer preferences. Changed audio/graphics are rechecked; missing managed copies are restored. Archive history is recorded only after successful processing; partial archives are retried safely.
+- Existing libraries get audio-fingerprint deduplication on their next import; source-history shortcuts are populated as files are encountered. ZIP shortcuts start after the first successful import using this version.
+- The waveform playhead now has a bright white line with a dark outline/cyan glow, cyan pointer and moving precise-time label, plus shading over elapsed audio. The marker remains visible during waveform analysis.
+- 80 XCTest cases passed, zero failures (`/tmp/kjmix-import-final-80-tests.log`). New cases cover async import return/UI scheduling, progress, cancellation/partial saves, errors, history persistence, unchanged ZIP extraction bypass, renamed audio, changed audio/CDG, missing media recovery and managed archive copies. Existing playback, singer and rotation tests also passed.
+- Import dialog and playing waveform rendered with isolated original test media at 1320 × 900. No personal media used in previews or distributions.
+- The release script records signing, Apple notarization, stapling and Gatekeeper results under `build-release/release-verification/KJMixPro-0.6.6-macOS/`. Only the current DMG is retained in `dist`.

+# KJMix Pro 0.6.5 (build 16) — native macOS appearance
+
+Verified on 3 November 2026.
+
+- Native SwiftUI sidebar list, contextual window title and venue subtitle, simplified toolbar.
+- System appearance by default, with persisted System / Light / Dark selection in Settings. Editors and workspaces inherit the choice; waveform, video and tone mixer use dedicated dark monitoring surfaces.
+- 73 XCTest cases passed with zero failures, including actual singer disclosure/navigation and rotation Add to Tonight, reorder and Start clicks. Log: `/tmp/kjmix-native-ui-tests-final.log`.
+- Light-mode library, rotation and settings rendered using isolated original demo data; dark-mode rotation inspected from the native UI test capture.
+- Final contrast-only change to playback-position labels compiled in the universal Release build.
+- Distribution contains only the current DMG. Signing, notarization, stapling and Gatekeeper results are recorded by the release script under `build-release/release-verification/KJMixPro-0.6.5-macOS/`.
+- This is a native macOS styling update, not a claim of Apple certification or an exhaustive accessibility audit.
