Phase 9 of the rebrand cascade. Sweep covers everything the Phase 8
frontend pass deliberately skipped: docs/, root markdown, scripts,
Cargo.toml descriptions, code comments that survived earlier
word-boundary sed, plus a handful of identifiers caught on the final
verify pass.

transcription-app changes:
- README.md, HANDOVER.md, KNOWN-ISSUES.md, run.sh — magnotia/Magnotia
  -> lumotia/Lumotia.
- docs/ — sweep across all subdirs except docs/handovers/ (preserved
  as immutable audit trail). Includes architecture-map references
  to magnotia_core::*, magnotia_storage::*, etc. now pointing at
  lumotia_*; dev-setup.md tracing output examples (lumotia_startup
  target); brief/ + superpowers/ + issues/ + whisper-ecosystem/ +
  audit/.
- Cargo.toml descriptions on 9 crates (core, audio, cloud-providers,
  hotkey, llm, mcp, plus referenced others).
- crates/core/src/{error,hardware,recommendation,paths}.rs +
  crates/audio/src/wav.rs + crates/llm/src/model_manager.rs +
  crates/cloud-providers/src/keystore.rs + crates/mcp/src/lib.rs —
  doc comments and a model-manager user-agent string.
- Caught on final pass: BroadcastChannel("magnotia_task_sync") -> ...
  ("lumotia_task_sync"); magnotia_locale i18n localStorage key
  renamed + migration shim added; CSS keyframe names
  magnotiaPulse / magnotiaBar / magnotiaFade renamed in the design-
  system kit; magnotia_viewer_item / magnotia_viewer_mode handoff
  keys renamed in HistoryPage + viewer/+page.svelte; src/assets/
  wordmark.svg text.
- src-tauri/src/lib.rs comment cleanup ("magnotia era" was sed'd
  to "lumotia era" earlier — restored).

Preserved (intentional):
- crates/core/src/paths.rs — keeps "magnotia" / "Magnotia" / ".magnotia"
  legacy detection strings in legacy_and_target_paths() so the
  migration shim can still find user data from the magnotia era.
- src/lib/stores/{page,focusTimer}.svelte.ts + src/lib/i18n/index.ts
  — migration call sites reference the legacy magnotia keys
  deliberately.
- docs/handovers/ — historical audit trail.

3. **`@ts-nocheck` is widespread.** `+layout.svelte`, `DictationPage.svelte`, `FilesPage.svelte`, `FirstRunPage.svelte` and the float/viewer/preview layouts all opt out of TypeScript. Type safety stops at the page boundary.
4. **`SettingsPage.svelte` is 2 484 lines.** Phase 9c handover already flagged this. `SettingsGroup.svelte` exists but the deeper restructure into seven progressive disclosure groups plus search has been deferred.
5. **`profiles` redirect is a dead route.** `+page.svelte:13` still rewrites `page.current === "profiles"` to `"settings"`, suggesting the old profiles page was removed but call sites may persist. Worth grepping and deleting the redirect after a release.
6. **Cross window settings sync uses `localStorage` `storage` events.** `float/+layout@.svelte` listens for `storage` to apply settings, while preferences use the dedicated `magnotia:preferences-changed` Tauri event.

- Linux rendering env vars are a launcher contract, not a runtime mutation. In development, use `npm run dev:tauri` / `./run.sh`; packaged Linux builds need an equivalent wrapper or `.desktop` `Exec=env` policy. `WEBKIT_DISABLE_DMABUF_RENDERER=0` remains the user opt-out for the DMA-BUF workaround.
- Close-to-tray works only on desktop (the `cfg!(not(target_os = "android"))` block). On Android, closing the activity terminates the process, which is the expected platform behaviour.
- The `prewarm_default_model` call is *not* wired here. `commands::models::prewarm_default_model` exists, but `setup` does not invoke it.

- `mark_morning_triage_shown(state, date: String) -> Result<(), String>` (`src-tauri/src/commands/rituals.rs:36`). Caller passes a YYYY-MM-DD string in the user's local timezone — Rust deliberately stays timezone-agnostic.

Standard CRUD: create / list / update / complete / uncomplete / delete a task, plus subtask CRUD (insert / list / complete) and a daily-completion-counts query for the Phase 8 Tasks-page momentum sparkline. The two LLM actions: `decompose_and_store` (break a parent task into subtasks via the local LLM with HITL feedback as few-shot exemplars) and `extract_tasks_from_transcript_cmd` (extract task lines from a recently-finished transcript, again with feedback exemplars).

## Watch-outs
- **No `ensure_main_window` guard.** Tasks UI lives in the main window AND in the always-on-top task float (which has the secondary-windows capability). The float can call list / complete / set-energy / list-recent-completions etc. — that's intentional — but it can also fire `decompose_and_store` and `extract_tasks_from_transcript_cmd`, which spend LLM tokens. If you want to lock this down, add the guard to the LLM-spending commands.
- **No `PowerAssertion`.** `decompose_and_store` and `extract_tasks_from_transcript_cmd` both run synchronous LLM inference for several seconds. macOS can App Nap them. Add `PowerAssertion::begin("magnotia LLM task decomposition")` and similar.
- **No `PowerAssertion`.** `decompose_and_store` and `extract_tasks_from_transcript_cmd` both run synchronous LLM inference for several seconds. macOS can App Nap them. Add `PowerAssertion::begin("lumotia LLM task decomposition")` and similar.
- **The patch shape passes `Option<String>` for every column.** Currently the storage layer's `update_task` uses COALESCE: `Some` overwrites, `None` preserves. This means there's no way to clear `notes` or `effort` to empty via `update_task_cmd` — you can only set them to a non-empty string. If a user wants to clear a field, they'd need a fresh task or a dedicated clear command.
- **Decompose stores subtasks one-by-one in a loop** (`:329`). Each iteration is a separate DB transaction. Acceptable for typical 37-step decompositions; if a future LLM produces 50 steps, batch the inserts.
- **`extract_tasks_from_transcript_cmd` returns just `Vec<String>` and does NOT insert.** Frontend chooses what to insert. Confusing because the sibling `decompose_and_store` *does* insert. Convention is dictated by UX (decomposition is one-click, extraction reviews-then-inserts).

Out only: clicks on the tray menu either hide/show the window directly or fire one event to the frontend (`lumotia:open-wind-down`). The tray does not read any state.
## Watch-outs
- The status menu item is hard-coded "Ready". There is no wiring to update it dynamically as the engine moves between idle / loading / recording. If you want a live status, you'll need to retain a `TrayIcon` handle in `AppState` (or somewhere similar) so a command can call `set_tooltip` / update the menu item text.
- The icon comes from `app.default_window_icon()` which is the packaged bundle icon (set in `tauri.conf.json` `bundle.icon`). Replacing the tray icon means re-running `tauri icon` or shipping a separate tray PNG.
- The `magnotia:open-wind-down` event payload is `()` — the frontend just needs to know "navigate to the wind-down page", and the page itself decides whether to render the ritual or a "you have not enabled this yet" stub.

Whisper without Vulkan (CPU-only desktop, Android without GPU drivers):
```sh
cargo build -p magnotia-transcription --no-default-features --features whisper
cargo build -p lumotia-transcription --no-default-features --features whisper

No Whisper at all (Parakeet only — useful for shrinking the binary and dropping `whisper-rs-sys`):
```sh
cargo build -p magnotia-transcription --no-default-features
cargo build -p lumotia-transcription --no-default-features

The `--no-default-features` form drops the `whisper_rs_backend` module entirely, so any sibling code holding a `WhisperRsBackend` will fail to compile. `LocalEngine`, `SpeechModelAdapter`, `load_parakeet`, and the streaming primitives stay available.

- **Drop is permanent.** A segment removed by anti-hallucination is gone before any other filter or LLM cleanup runs. If a real-world transcript ever has a legitimate segment that exactly matches "Thanks." (e.g. in a meeting where someone said only "Thanks." in response to a question), it gets dropped. The exact-match policy on `HALLUCINATION_TRAIL_PHRASES` is the trade-off — substring-match would have a much larger false-positive rate.

Magnotia's `Segment.text` field already holds just the spoken text — the timing lives in `start: f64` and `end: f64` — so "timestamp stripping" falls out of using the text field alone. The work here is the whitespace pass and empty-segment filter.

1. **Tokenise the prompt.** `model.str_to_token(prompt, AddBos::Never)` — the `AddBos::Never` matters: `render_chat_prompt` already emits the BOS token via the Qwen chat template.
2. **Empty-prompt short-circuit.** If tokenisation produced zero tokens, return `Ok(String::new())` without touching the GPU.
3. **Preflight context window.** `preflight_context_window(prompt_tokens.len(), config.max_tokens)` (`:436`) errors with `EngineError::PromptTooLong { ... }` when `prompt_tokens + max_tokens + 64 reserve` exceeds the 8192 cap. Fixed sizing — see the watch-out about MAX_CONTEXT_TOKENS below. This was RB-10 from the 2026-04-22 review (`docs/issues/llm-prompt-preflight.md`).
4. **Compute thread count.** `gpu_offloaded = use_gpu && gpu_layers >= model.n_layer()`. The compiler can prove this is trivially true today because `gpu_layers` is `u32::MAX` whenever `use_gpu` is set. The redundant check is documented inline (`:169-173`) as a placeholder for future per-layer residency parsing of llama.cpp's log output. `inference_thread_count(Workload::Llm, gpu_offloaded)` from `magnotia_core::tuning` returns the physical core count adjusted for the workload class.

6. **Prefill.** A single `LlamaBatch` is built with every prompt token, the last token marked as the only logits-bearing position, then `ctx.decode(&mut batch)`.
7. **Sample loop.** A custom sampler chain (`build_sampler`, `:400`) is built from `config.grammar` (optional GBNF), `temperature`, and a fixed `GENERATION_SEED = 0`. For temperature 0.0 (the only value the high-level surfaces use) we attach `LlamaSampler::greedy()` after the optional grammar. For non-zero temperatures we attach `temp` then `dist` with the seed.

- **Mutex-protected single model.** `LlmEngine` allows only one model loaded at a time. Two concurrent `generate` calls serialise on the underlying llama context (each call builds its own `new_context` from the shared `LlamaModel`, so the model weights are shared but the KV cache is per-call). The Tauri layer wraps each high-level call in `tokio::task::spawn_blocking` because `generate` is sync and blocks the executor for hundreds of milliseconds at minimum.
- **`MAX_CONTEXT_TOKENS = 8192` is a process-wide cap** regardless of which tier is loaded. The 27B tier's native context is much larger; we are deliberately leaving headroom on the table to keep the preflight predictable. Surfaced in the slice README's debt section.
- **`u32::MAX` GPU offload.** The engine has no concept of partial offload. On a low-VRAM machine that cannot fit all layers, llama.cpp will emit warnings and fall back to mixed CPU/GPU automatically, but our `gpu_offloaded` boolean tells `inference_thread_count` we are fully GPU-resident. When this matters (battery, throttling), the consumer is `magnotia_core::tuning` — it picks a bigger thread count when it thinks the CPU is idle. Trivial-true today; tracked as observability gap (commit `052265b`).

- **GBNF parser quirks.** llama-cpp-2's GBNF is strict about whitespace. Each grammar in [`llm-prompts-and-grammars.md`](llm-prompts-and-grammars.md) carries an explicit `ws` rule and `r#""#` raw strings — refactors that try to "tidy" the grammar literal by stripping the trailing newline have, in the past, broken `LlamaSampler::grammar` with cryptic parse errors.
- **Stop sequences are post-detokenisation substring matches.** They run on the running `String`, not on token ids. A multi-byte stop string that splits across a token boundary still matches because the UTF-8 decoder buffers partial bytes. A stop string that contains characters the chat template re-emits as part of normal output (e.g. a literal `<|`) will trigger early termination — only use the EOG sentinels we already use.
- **Chat template fallback to ChatML.** If `model.chat_template(None)` errors, we warn-log and use `LlamaChatTemplate::new("chatml")`. The warn-log fires once per `generate` call, not once per session — keep an eye on log volume if a non-Qwen model is ever loaded.

- **`magnotia-core` is the universal lower bound.** Every other crate in the workspace depends on it.

It calls `magnotia_storage::init` at startup, registers the SQLite pool as Tauri-managed state, and every command in `src-tauri/src/commands/*.rs` reaches into `magnotia_storage` for persistence and `magnotia_core::paths` for filesystem locations.

- **Slice 3 (audio + transcription)** consumes `magnotia_core::types::{AudioSamples, Segment, Transcript}` and `magnotia_core::constants::{WHISPER_SAMPLE_RATE, WHISPER_CHANNELS, PARAKEET_*, CHUNK_INTERVAL_MS}`.

## Data flow / contract
- All variants are `Serialize`-able. `std::io::Error` does not derive `Serialize`, so the `Io` variant uses a custom `serialize_with` adaptor (`serialize_io_error` at `crates/core/src/error.rs:53`) that emits the error's `Display` string.
- Variants do not carry source-location information. The storage CRUD layer attaches context via the typed `magnotia_storage::Error::Query { operation, source }` shape; the `operation` label survives into `MagnotiaError::Storage.operation` at the boundary.
- Variants do not carry source-location information. The storage CRUD layer attaches context via the typed `lumotia_storage::Error::Query { operation, source }` shape; the `operation` label survives into `MagnotiaError::Storage.operation` at the boundary.
- Tauri serialises the enum verbatim. The frontend can switch on the discriminant by reading the JSON tag (the variant name).
## Watch-outs
- **No `From<sqlx::Error>` impl in core.** The storage crate manually converts every sqlx error to a typed `magnotia_storage::Error::Query` with an operation label, then `From<storage::Error> for MagnotiaError` (defined inside the storage crate to avoid a `core -> storage` dependency cycle) flattens it into `MagnotiaError::Storage { kind, operation, detail }` at the boundary. Adding an automatic `From<sqlx::Error>` would erase the per-site operation label; the explicit map step is intentional.

Adding an automatic `From<sqlx::Error>` would erase the per-site operation label; the explicit map step is intentional.
- **No `Source` chain.** `thiserror` would let you wrap source errors in fields with `#[source]` for chained `Display`. Today every wrapped error is flattened to `String` to keep the JSON shape simple.
- **`Other(String)` is a leaky bucket.** New error categories should get their own variant rather than reaching for `Other`. Audit `Other` usage if the error log starts hiding distinct failure modes behind the same string.

SQLite re-applies the pragma on each new pool connection because we set it via the connect options... but actually we don't, we set it after `connect_with`. **This is a latent issue worth verifying:** if a second pool connection opens later, foreign keys may not be enforced on it.

## What Lumotia is in 60 seconds
Magnotia is a local-first dictation desktop app. You press a hotkey, you speak, your speech becomes formatted text on disk and on the clipboard. Everything that touches your voice or your transcript runs on your own machine. Zero telemetry, zero analytics, no calls home unless you turn on auto-update.

Everything that touches your voice or your transcript runs on your own machine. Zero telemetry, zero analytics, no calls home unless you turn on auto-update.
It is a Tauri 2 app. The shell is Svelte 5. The brain is a Rust workspace of nine crates. Speech-to-text runs through Whisper (whisper-rs) by default with Parakeet (transcribe-rs ONNX) as an alternative. Optional cleanup runs through a local llama-cpp-2 LLM (Qwen3.5 / 3.6, four-tier model picker). Transcripts live in a SQLite database with a FTS5 full-text index. A standalone `magnotia-mcp` binary opens that database read-only and serves four tools over the Model Context Protocol so external agents can read your history without write access.

The Linux evdev listener (`crates/hotkey/src/linux.rs`) watches `/dev/input/event*` after a one-time access check. The user-configured combo (default `Ctrl+Shift+R`, parsed from a Tauri-style string by `HotkeyCombo::from_tauri_str`) is checked against modifier state and key events. On match the listener emits `HotkeyEvent::Pressed` over an `mpsc::Sender` it was given at startup. On release it emits `HotkeyEvent::Released`. Hotplug is supported. macOS and Windows fall back to the `tauri-plugin-global-shortcut` plugin via the same command surface.
The `commands::hotkey::start_evdev_hotkey` command (`src-tauri/src/commands/hotkey.rs:67`) holds the listener inside `tauri::State` and runs a forwarder task that translates each event into a Tauri global event:

**Owner:** slice 03 (`lumotia-audio`).
`MicrophoneCapture` (`crates/audio/src/capture.rs`) opens the selected `cpal` input device. It rejects monitor sources, RMS-validates the first samples for "is this actually live audio", and forwards device hot-unplug as `CaptureRuntimeError` rather than panicking. Sample format is normalised to `f32`. Samples leave the capture thread as `AudioChunk { samples, channels, sample_rate }`.

**Owner:** slice 03 (`lumotia-audio`).
`StreamingResampler` (`crates/audio/src/streaming_resample.rs`) runs `rubato` sinc resampling to 16 kHz mono. The streaming variant is used here; a separate `resample_to_16khz` (`crates/audio/src/resample.rs`) is used for file imports in phase F (file-import path, see end of this document). The 16 kHz mono PCM is what every transcription engine downstream wants. The constant `WHISPER_SAMPLE_RATE` lives in `crates/core/src/constants.rs` (slice 05) and the `pcm-processor.js` AudioWorklet in `static/` hard-codes the same number — they must move together.

The Silero-based VAD module in `magnotia-audio` (`crates/audio/src/vad.rs`) is a stub today (the candidate `ort` crate revision conflicts with Parakeet's `transcribe-rs`). Live capture therefore uses an energy-based fallback, `RmsVadChunker`, in `magnotia-transcription` (`crates/transcription/src/streaming/rms_vad.rs`). It groups samples into chunks at silence boundaries with hysteresis, returning `VadChunk { samples, start_sec, end_sec }` to the runtime. WAV append happens in parallel via `WavWriter::append_chunk`.

If the user has a model loaded and "LLM cleanup" enabled, `commands::llm::cleanup_transcript_text_cmd` (`src-tauri/src/commands/llm.rs:363`) is called from the frontend. It composes:

The frontend can call `extract_content_tags_cmd` (`src-tauri/src/commands/llm.rs:408`). `LlmEngine::extract_content_tags` runs the `CONTENT_TAGS_SYSTEM` prompt under the `CONTENT_TAGS_GRAMMAR` GBNF and returns `ContentTags { topic, intent }` where `intent` is constrained to `INTENT_CLOSED_SET` (six values, also enforced redundantly in Rust). The result writes to `transcripts.llm_tags` (added in migration v14).

**Owner:** slice 04 (`lumotia-llm`) → slice 05 (`lumotia-storage`).

Each tool maps to the corresponding `magnotia_storage` function. There is no auth at the MCP layer; stdio is the trust boundary. Any future HTTP / SSE transport needs an auth design before it ships.
