Summary

• New Settings > Integrations > AI channels group: "Hide AI channels" (block list) and "Label suspected AI channels" (warn list), both off by default. Nothing is downloaded or scheduled while both are off.
• The list comes from the signed mirror at ailist.flow-tube.org (Flow-Tube/AIlist): Ed25519 manifest check with the existing Curves.verify, SHA-256 per file, daily deltas, atomic store in noBackupFilesDir, daily WorkManager refresh. The list is never backed up or synced.
• Hiding joins FeedExclusions.hidesFromRecommendations (Home, chips, Home cache, related, autoplay, rank()), plus search videos and the Shorts V2 feed. Subscriptions and subscribed channels are never filtered.
• Video.channelHandle is read by the video, lockup (byline, then avatar), related, mix and NewPipe parsers, and a channel id to handle index covers rows that carry only an id.
• Warn-list channels get a "Suspected AI" card label. A listed channel's page shows a banner with "Show its videos", undone from Hidden from you > Allowed AI channels.
• List source: a custom https server with an optional public key (raw base64 or the pipeline's PEM) for self-hosted or other public instances. Switching source starts from a fresh snapshot.
• Reporting (opt-in, needs a submitter name): "Report AI channel" in the video menu opens a confirm page and sends the channel handle, video link and name to AiSList.

• I ran any additional flavor-specific build or test tasks affected by this change: :app:testFossDebugUnitTest (5936 tests, 0 failures), :app:compileFossDebugKotlin, ktlintCheck, nightly_notes.py --check
• I manually tested the affected behavior on an Android device or emulator.

Test device and Android version: Xiaomi 2311DRK48G, HyperOS on Android 16 (filter, search, channel banner, allow and hide again); Android emulator, API 37 (list source, wrong key refused, reporting up to the confirm page)

Screenshots or recordings

Risk and compatibility

• Network: ailist.flow-tube.org (or the chosen server) about once a day only while a switch is on; api.aisloplist.com only when the user confirms a report. Both are listed in privacy.md.

• Preferences: three profile keys for the switches and allowlist, two profile keys for reporting, two device keys for the list source. No Room changes.

• Background work: one unique periodic worker with a random start time, plus a one-off run when a switch is turned on or the source changes.

• List downloads use their own 5 minute call timeout; the shared 60 s one cut off the snapshot on slow links.

• The change does not introduce secrets, private data, or unexpected telemetry.

• New user-facing text uses Android string resources.

• Dependency and lockfile changes are intentional and limited to this PR.

• Room schema changes include the required version bump and migration, or this PR does not change the Room schema.

• Breaking changes and upgrade steps are clearly documented.
