F10 — studyvis:// registered as an OS deep link (plugin config, capability, argv forwarding; subscribePairDeepLink helper lands unwired until the friends cluster routes it into the accept flow). N4 — quit-confirm scaffolding: SessionActiveFlag, session_set_active, app_quit, quit-requested event; macOS Cmd+Q rerouted through a custom menu item since NSApp.terminate can't be intercepted. D2 — corrupt app.db is set aside and recreated with an explanatory dialog instead of a startup panic; healthy-but-unopenable data is never destroyed. D6 — a DB created by a newer build is refused with a distinct 'update needed' dialog, no rename/recreate. R4 — sessions_delete / sessions_clear_all commands (tx-scoped, audit events included). D3 — friends_export / friends_import commands (sealed-box to the user's own X25519 key, SVFB v1 format, upsert on import). A4 — model downloads resume via HTTP Range from the surviving .tmp, hasher seeded from existing bytes. X4 — system_fetch_latest_version command (bare GET, no identifiers, 10s timeout; UI toggle ships OFF by default later). X5 — ad-hoc signingIdentity '-' with hardenedRuntime false so the sidecar's DYLD-based dylib resolution survives release signing. X6 — dormant tauri-plugin-updater removed.

A2 — malformed/empty model responses become an internal 'uncertain' verdict: streak and latches untouched, sample excluded from focusedPct via a separate skipped tally; 'uncertain' provably never reaches the signed ai-alert wire or the audit vocabulary. A3 — off-task judgments carrying >= floor on-topic confidence are skipped as uncertain; floor persisted as off_task_confidence_floor (default 0.6) with a Settings -> AI slider (UI min 0.05; 0 stays a programmatic disable). A5 — the tick re-reads the sidecar port after the capture await and bails/reschedules when the watcher respawned the server. A6 — duration-based cadence backoff (2 slow ticks engage x2 interval, 3 normal ticks recover) with a one-shot in-voice notice; replaces the dangling 'thermal-aware notice' comment. A4 — interrupted downloads persist their real byte offset (terminal events hardcode 0; the container stashes downloading-phase counts) and the picker shows an honest 'Resume download' affordance. 487 unit tests pass (35 added); tsc/lint/tokens/strings/prettier green.

S2 — PTT can no longer latch the mic open: pttStore.reset() on every session start/teardown (host/join/SessionView), plus a 120s stuck-key guard tuned for macOS global hotkeys (no key-repeat events); a stale latch can never bring a fresh session's first audio track up live. R1 — snapshotFocusForReport returns score:null when no confident samples exist; the report renders a calm no-score state instead of a fabricated 100/100 gauge and stats averages skip nulls. S3 — camera on/off toggle flips track.enabled (stream stays monotonic), broadcasts a backward-compatible camera-state action so peers render an explicit camera-off tile, and pauses the AI loop without counting ticks against the user. S4 — audio output picker (feature-detected; hidden on macOS WKWebView) and a per-peer local-only volume slider. U2 — a §10-pattern waiting tile when alone in an active session. F4 — per-peer RTCPeerConnection state surfaces as connecting/failed tile badges; transient 'disconnected' stays 'connecting', no TURN. N4 — session_set_active wired at one status-keyed chokepoint and a quit-requested listener with an in-app confirm dialog backing the wave-1 Rust scaffolding. 504 unit tests pass (17 added); all frontend gates green.

F2 — NetworkCategory connection panel: per-relay state rows polled while visible, state shown by glyph + text, never color alone. F3 — user-supplied relay URLs and a TURN server persist in settings and flow through the existing relayConfig/buildIceOptions seams; URL validation mirrors new WebSocket() so a malformed saved relay can't white-screen the boot (inbox/presence joins also guarded); the turnPreference radio finally does something when TURN exists. F5 — 45s post-peer-arrival stall timer: 'connected to the network but couldn't establish a direct link' with a pointer to relay/TURN settings. F6 — invites re-attempt when the friend flips online within the retry window, deduped per recipient+session so a friend can never receive the same invite twice; offline-friend vs relay-down failures read differently. F7 — best-effort goodbye on quit flips presence offline immediately; wire-compatible both directions (goodbye omits ts so older receivers drop it and age out via the 60s window; I2 receiver-clock intact). F9 — QR error correction M→Q, larger module size, and a freshness note for the ~10-minute secret. F10 — OS-delivered studyvis://pair links prefill (never auto-connect) the join form; a second link can't discard a half-typed code. F8 — settings copy, README, PLAN §2/§7, and ARCHITECTURE stop promising a public TURN fallback that no longer ships. 540 unit tests pass (36 added); build, tsc, lint, tokens, strings, contrast, prettier all green.
