ffprofanity 1.4.0 (2026-09-28)

Features
- Auto drift correction: watches the site's own subtitle track and
self-syncs as the movie plays (native-track cuechange pairing,
offset + rate model, auto anchors capped/validated; opt-out in
Options → Timing Sync)
- Manual and automatic sync are now mutually exclusive: moving the
offset slider (popup, Options, or Alt+←/→) immediately disables
auto-sync with an on-page notice; re-enabling auto takes the slider
back to 0 on lock-on. No double-correction in either direction.
- "Sync now" (popup / Alt+S) now reports its result in the popup:
correction applied, anchors needed, or anchor rejected.
- Firefox Android: popup opens as a tab there — tab-aware targeting,
saves are verified (failed writes now say "Save failed — try again"),
toggle falls back to direct delivery if the background is asleep.
- Popup's Audio Sync mode line updates live when settings change
elsewhere (no reopen needed); fixed settings form init order.

Detection
- Wordlist additions from a real-movie audit (Quantum Supremacy 2025,
1116 cues): shitter/shitters, bloody, frickin/frickin'/fricking,
friggin/friggin'/frigging. No obfuscated forms missed.

Code health
- Fixed all 230 noUncheckedIndexedAccess type errors with real guards;
no tsconfig weakening, no !/as any, no behavior change.

• Pre-compiled phrase and obfuscation regexes in ProfanityDetector constructor
  (eliminates per-call RegExp construction in detect())
• Pre-compiled single SUBSTITUTION_REGEX at module level for normalizeText()

• Added binary search to CueIndex.getNextCues() (O(log n) vs O(n))
• Added CueIndex.getProfanityCueCount(), replaced cues.filter() at hot paths
• Skip RAF loop work when video is paused (keep loop alive for resume)
• Replace unconditional cues.sort() with isSorted check (merge-aware)
• Removed dead normalizedText variable in detect()
• Removed redundant inline sort in PlutoTV accumulation path

• Re-export ProfanityWindow type for content script import
• Add tabId guards in background message handler
• Type-annotate DNR rules as browser.declarativeNetRequest.Rule[]
• Cast TextTrackCue to VTTCue for .text property access
• Cast nativeOpen.apply() through unknown to XMLHttpRequest
• Type-annotate .text() callback param in fandango

Religious compound profanity support and false positive fixes:
- Add explicit combinations (blocked at all levels)
- Update phrase regex to match hyphenated variants
- Whitelist "damnable" at Low sensitivity (theological term)
- Remove "naked" from wordlist (not profanity)
- Verified zero false positives on two religious sermon SRTs
