# Known issues

Tracked limitations and partial implementations in the current codebase. Each entry points at the code that owns the gap so future work can find it.

## Power management

### KI-01 — macOS App Nap guard pending Apple Silicon runtime verification

**Status:** macOS code path compiles and the registry tests pass, but runtime behaviour against actual OS idle-throttling has not been confirmed on Apple Silicon hardware. Also tracked internally as **RB-08**.

**Source:** [`src-tauri/src/commands/power.rs:73`](src-tauri/src/commands/power.rs#L73) (`PowerAssertion::begin`), [`src-tauri/src/commands/power.rs:140`](src-tauri/src/commands/power.rs#L140) (`objc_bridge`).

**Impact:** Long live-dictation sessions on macOS may still be slowed or paused by the OS until verified end-to-end on hardware.

**Workaround:** Keep the app window focused, or move the cursor periodically. For testing, App Nap can be disabled globally with `defaults write NSGlobalDomain NSAppSleepDisabled -bool YES` (revert with `-bool NO`).

### KI-02 — Linux idle inhibit ✓ fixed in v0.1

**Status:** Resolved. `acquire_idle_inhibit` now calls `org.freedesktop.login1.Manager.Inhibit`
via zbus (blocking, offloaded to `spawn_blocking`) on recording start, holding the returned file
descriptor. `release_idle_inhibit` closes the fd on recording stop, which atomically releases the
lock. The inhibit scope is `idle:sleep:handle-lid-switch` in `block` mode.

If D-Bus is unavailable (non-systemd containers, exotic distros), the call fails gracefully with a
`tracing::warn!` and recording continues — the workaround below remains valid in those edge cases.

**Source:** [`src-tauri/src/commands/power.rs`](src-tauri/src/commands/power.rs) (`acquire_idle_inhibit`, `release_idle_inhibit`, `linux_inhibit` mod).

**Workaround (edge cases only):** Wrap launch with `systemd-inhibit --what=idle:sleep:handle-lid-switch ./run.sh` if logind is not available.

### KI-03 — Windows sleep prevention ✓ fixed in v0.1

**Status:** Resolved. `acquire_idle_inhibit` now calls
`SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED)` on recording start.
`release_idle_inhibit` calls `SetThreadExecutionState(ES_CONTINUOUS)` to restore normal behaviour.
Display sleep is intentionally NOT blocked — the user is dictating, not watching the screen.

**Source:** [`src-tauri/src/commands/power.rs`](src-tauri/src/commands/power.rs) (`acquire_idle_inhibit`, `release_idle_inhibit`, `windows_inhibit` mod).

**Workaround (edge cases only):** If the power plan has a policy override that blocks `SetThreadExecutionState`, set the active sleep timeout to "Never" while dictating.

## Cloud providers

### KI-04 — `lumotia-cloud-providers` crate is not user-exposed

**Status:** The crate is a declared workspace dependency in [`src-tauri/Cargo.toml:36`](src-tauri/Cargo.toml#L36) and compiles into the binary, but no Tauri command, page, or settings field invokes `store_api_key` / `retrieve_api_key`. There is no UI to enter or store a cloud API key in the current build.

**Source:** [`crates/cloud-providers/src/keystore.rs`](crates/cloud-providers/src/keystore.rs). The `TODO` in the doc comment captures the planned migration to OS-native credential storage (the `keyring` crate or equivalent) before the feature is wired up.

**Impact:** None for end users today (no exposed surface). When the feature is wired post-launch, cross-restart persistence must land before any "save key" UX ships, otherwise saved keys reset on every restart.

**Workaround:** N/A.

## Frontend

### KI-05 — Dual theme system: `settings.theme` and `preferences.theme` coexist

**Status:** Theme is stored twice. The legacy `settings.theme` ("Dark" / "Light" / "System", localStorage-only) is bound to two `SegmentedButton` controls in `SettingsPage.svelte`. The canonical `preferences.theme` ("dark" / "light" / "system", Tauri-persisted via `save_preferences`) is what the DOM and runtime actually consume. A migration `$effect` in `src/routes/+layout.svelte` (and the secondary `+layout@.svelte` files for `/preview`, `/viewer`, `/float`) syncs `settings.theme` → `preferences.theme` whenever the legacy value changes.

**Source:**
- [`src/lib/stores/page.svelte.ts:61`](src/lib/stores/page.svelte.ts#L61) (legacy default: `theme: "Dark"`)
- [`src/lib/stores/preferences.svelte.ts:30`](src/lib/stores/preferences.svelte.ts#L30) (canonical default: `theme: "dark"`)
- [`src/routes/+layout.svelte:61-68`](src/routes/+layout.svelte#L61) (migration `$effect`)
- [`src/lib/pages/SettingsPage.svelte:1118`](src/lib/pages/SettingsPage.svelte#L1118), [`:2360`](src/lib/pages/SettingsPage.svelte#L2360) (UI bindings still on the legacy field)

**Impact:** No user-facing bug; theme switching works. The cost is code complexity and a small race window where preference fan-out can lag behind a `settings.theme` change. The `$effect` is lightweight (string compare plus a debounced persist when the mapped value differs), not a hot-loop performance problem despite earlier framing.

**Resolution (deferred):** Switch the two `SettingsPage` bindings to `preferences.theme` with mapped options, retire the migration `$effect` in all four route layouts, drop `theme` from `SettingsState`, and add a one-shot localStorage migration that copies any historical `settings.theme` into `preferences` on first run after the cleanup. Touches ~5 files including the 2 484-LOC `SettingsPage.svelte`; deferred from the v0.1 polish pass to avoid a moderate-risk frontend change immediately before launch.

**Workaround:** N/A.

## Engine architecture (Phase A)

### KI-06 — `transcribe_file` and live-transcription commands not yet rewired through `Orchestrator`

**Status:** Phase A introduced the `TranscriptionProvider` async trait ([`crates/cloud-providers/src/provider.rs`](crates/cloud-providers/src/provider.rs)), `EngineRegistry` ([`crates/transcription/src/registry.rs`](crates/transcription/src/registry.rs)), and `Orchestrator` plus `LocalProviderAdapter` ([`crates/transcription/src/orchestrator.rs`](crates/transcription/src/orchestrator.rs)). The abstractions compile, are object-safe, and pass unit tests against a mock provider. The existing dictation path ([`src-tauri/src/commands/transcription.rs`](src-tauri/src/commands/transcription.rs)) still calls `LocalEngine::transcribe_sync` directly via `pick_engine`, not through the orchestrator. Live and meeting commands likewise route around the orchestrator.

**Source:** [`src-tauri/src/commands/transcription.rs:29`](src-tauri/src/commands/transcription.rs#L29) (`pick_engine`), [`src-tauri/src/commands/live.rs`](src-tauri/src/commands/live.rs), [`src-tauri/src/commands/meeting.rs`](src-tauri/src/commands/meeting.rs).

**Impact:** None at runtime. The orchestrator path is dormant until a follow-up commit migrates the call sites. Cloud providers (Phase G) cannot be exercised end-to-end until this rewire lands.

**Resolution (deferred):** Phase A.1 follow-up commit. Build an `EngineRegistry` at app boot (one `LocalProviderAdapter` per `LocalEngine`), inject `Arc<Orchestrator>` into `AppState`, replace `pick_engine` plus `engine.transcribe_sync` chunking-loop calls with `orchestrator.transcribe(audio, &profile)` per chunk. Keep the chunking strategy in the command layer (it is a strategy concern, not a dispatch concern). Tests should cover both paths against a mock provider before touching the real engines.

**Workaround:** N/A. Existing path works as before.

## How to add an entry

When shipping a partial implementation or known limitation, add a `KI-NN` entry here with the four standard fields: **Status**, **Source** (file:line), **Impact**, **Workaround**. Link from the affected module's doc comment back to this file by ID.
