While WebDAV or Google Drive is the selected cloud sync backend, the native Readest Cloud book/progress/note channels are gated off and the file-sync engine owns library data end to end: - isSyncCategoryEnabled returns false for book/progress/note (and their legacy aliases) when a third-party provider is selected. A runtime override, deliberately not written into syncCategories: the user's own toggles persist and take effect again on switch-back. Account channels (settings, stats, dictionaries, fonts, textures, OPDS catalogs) always stay native. - persistActiveCloudProvider is the single write path for provider switching, used by the chooser, both connect/disconnect flows, and the Drive OAuth callback (which previously bypassed the cross-window broadcast). The broadcast carries ONLY the enabled flags plus providerSelectedAt, never credentials or sync cursors, and only on switch events, so a stale window's routine save cannot revert a switch. - buildWebDAVConnectSettings no longer pre-sets enabled: activation belongs to withActiveCloudProvider, so the fresh-connect path now gets the syncBooks auto-flip and the providerSelectedAt stamp. - Sync health: fileSyncStore records lastError per backend; the durable lastSyncedAt stays in provider settings. The SettingsMenu sync row reads Synced via provider / Sync failed and its tap (with pull to refresh and BackupWindow, all routed through pullLibrary) runs the file engine via the shared runActiveFileLibrarySync helper instead of a gated native pull that would toast undefined book(s) synced. - Mixed-fleet detection: while gated, the auto-sync interval runs a read-only probe of /api/sync since providerSelectedAt; any newer book row means another device still syncs natively, and a once-per-session notice explains the fork instead of leaving it silent. - Readest-Cloud-only affordances hide while a third-party provider is selected: the quota row becomes a caption naming the active provider, Auto Upload disappears from the menu and command palette, the BookItem upload badge and the Transfer Queue Upload All button hide. - providerSelectedAt added to both provider settings types and the backup blacklist. Stacked on the quota-decoupling change for #4959; requires the metadata-parity change so gated channels lose nothing users can see. Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

TODOS
Cloud Sync provider selection follow-ups (deferred by /autoplan, 2026-07-06)
Deferred from the Cloud Sync provider-selection plan (#4959/#4380). See the Decision Audit Trail in the plan for reasoning.
- Pre-switch "download all Readest Cloud books" affordance so a fresh device gets full library completeness when a third-party provider is selected. (S)
- Library-page sync-status indicator for the active third-party provider (fileSyncStore already exposes aggregate progress). (S)
- Account page active-provider chip. (XS)
- File-engine parity: reading stats + per-book viewSettings sync via the file layout (readingStatus/tags parity shipped as its own PR). (M)
- Server-side quota error code (
code: 'quota_exceeded', mirroring the share import route) so the client stops string-matching 'Insufficient storage quota'; message drift silently restores retry behavior. (S) - Pre-existing: Manage Sync "Books" category gates metadata rows but NOT
binary uploads to Readest Cloud (
queueUploadnever consultsisSyncCategoryEnabled('book')despite the category docs claiming it) — align behavior or docs. (S) - Sentry
cloudSyncProvidertag: Sentry tagging is Rust-mediated (set_webview_infopattern insentry_config.rs); add aset_cloud_sync_providercommand + before_send tag so sync-related reports carry the active provider. Console log lines ship in the meantime. (S, needs src-tauri)

TTS listening engine follow-ups
- Cross-section gapless playback: preload and schedule the next section's first sentence so chapter boundaries are as seamless as sentence boundaries. (M)
- Buffer-ahead indicator in the TTS scrubber (show the prefetched region, YouTube-style). (S)
- Lock-screen ±10s seek offsets in addition to prev/next sentence. (S)
- Persist measured sentence durations per book so a reopened chapter starts with an exact timeline instead of estimates. (S)
- Worker offload for decode + WSOLA if device profiling shows main-thread jank on low-end Android. (S)
- Sticky TTSBar scrubber (panel + lock screen only in the first release; recorded as deliberate in decision #24). (S)
- Provider-agnostic voice source hedge: local neural TTS (e.g. Piper/Kokoro WASM) plugging into WebAudioPlayer/SectionTimeline — the engine is designed for this; see "Strategic framing" in the plan. (L)
- Background chapter prefetch (convert timeline estimates to exact durations ahead of playback). (M)
- Background TTS: decouple session ownership from the reader view via an app-level TTSSessionManager so closing the book keeps TTS playing (headless text supply via section.createDocument(), CFI re-anchoring for highlights on reattach, library now-playing pill). Decided matrix: close book = keep playing; reopen same book = seamless reattach (adopt session, redispatchPosition, lazy doc swap at next section); open a DIFFERENT book = TTS stops; explicit stop / sleep timer = stops.
