docs(brief): add reticular activating system appendix

The RAS is the brainstem network gating which sensory inputs reach
conscious cortical attention, modulated top-down by prefrontal goals.
RAS dysfunction is documented in ADHD, autism spectrum, and the wider
neurodivergent population that is Corbie's beachhead audience.

The appendix maps three RAS failure modes to existing Corbie features:

- Temporal salience gating failure -> time blindness
  -> visual countdown timers, progress rings.
- Arousal escalation failure -> task-initiation freeze
  -> AI micro-steps, just-start timer.
- Suppression failure -> sensory over-distraction
  -> WIP limits, reduce-motion defaults, anticipatory nudges.

Plus the personalisation grant connection: continual on-device
adaptation to user idiolect reduces load on a compromised attention
gate, which is the core value to neurodivergent users beyond raw
accuracy improvement.

Companion CORBEL-Main agent-side doctrine at
stonework/rules/agent-ras-protocol.md frames the same mechanism for
Wren's own context-economy discipline.

-## [Unreleased]
-
-## [0.1.0] - 2026-MM-DD <!-- replace with tag date on tag day -->
-
-### Added
-
-- **Dictation with on-device speech recognition.** Speak naturally; Lumotia transcribes locally using Whisper or Parakeet. Six Whisper variants (Tiny through Distil-Large v3) and Parakeet for lower-latency English transcription. The first-run hardware probe selects the fastest-accurate pair for your machine. Models download once and run entirely offline.
-- **Live streaming transcription.** Audio is processed as you speak rather than in one batch at the end, so you see results as they arrive. Speech-gated chunking and a duplicate-boundary filter keep the output clean.
-- **Transcript cleanup without touching your original.** A rule-based pass removes filler words, collapses repetition, and applies consistent spelling. If you have a local LLM model downloaded, it runs a second pass for natural-language polish. Your raw Whisper transcript is always preserved — cleanup is additive, never destructive.
-- **Automatic task extraction with a safe fallback.** Lumotia identifies action items from your transcript using either the local LLM or a rule-based verb-list extractor. If the LLM fails, the fallback runs silently and tasks still appear.
-- **MicroSteps and a 5-minute focus timer.** Any extracted task can be broken into 3–7 concrete sub-steps. Select a MicroStep to start a 5-minute timer scoped to that one step, so you can work on one thing at a time.
-- **History with full-text search.** Every transcript is indexed and searchable. Filter by date, tag, or keyword. Open any past transcript in the editor to review or correct it; edits autosave.
-- **Markdown export with YAML frontmatter.** Export any transcript as a Markdown file ready for Obsidian or any plain-text workflow. One button, native save dialog.
-- **Read-only MCP server.** An optional `lumotia-mcp` binary lets Claude Desktop, Cline, Cursor, or any MCP-compatible client read your transcripts and tasks over a local stdio connection. It cannot write, edit, or delete anything.
-- **First-run onboarding flow.** A short guided setup covers microphone selection, model download, and a practice recording with a pre-supplied prompt, so you know what to say.
-- **Per-profile custom vocabulary.** Add domain-specific terms to a profile and Lumotia feeds them to the transcription engine as hints, reducing misrecognition of names and jargon.
-- **Content tags and topic suggestions.** Lumotia suggests tags from your transcript. Promote them to your manual tag list with one click, or ignore them.
-- **Keyboard-navigable throughout.** The full capture flow — record, review, extract tasks, start a timer, export — is completable without a mouse. Focus rings are visible on every interactive element. `prefers-reduced-motion` is respected app-wide.
-
-### Privacy
-
-- All transcription, cleanup, and task extraction runs on your device. No audio, transcript, or task data is sent anywhere.
-- No telemetry, no analytics, no crash reports leave the machine unless you explicitly bundle one for a support request.
-- An optional local activation log records when the hotkey fires. It never leaves your machine and can be disabled in Settings → Privacy.
-- The optional MCP server is read-only and communicates over stdio only — no network listener, no remote access. Enabling it gives your MCP client read access to your full transcript history; treat it accordingly.
-- Full disclosure: `docs/release/privacy-and-ai-use.md` (link added when that page lands).
-
-### Known limitations
-
-See `docs/release/v0.1-known-limitations.md` for the full list. Brief summary:
-
-- **macOS App Nap** may pause Lumotia when its window loses focus during long sessions. The protection code is in place but not yet verified on Apple Silicon hardware.
-- **Linux idle inhibit is not wired.** The compositor may lock or suspend during a long dictation session. Workaround: launch with `systemd-inhibit --what=idle:sleep lumotia` or raise your system screen-lock timeout.
-- **Windows sleep prevention is not yet implemented.** Set your active power plan's sleep timeout to "Never" while dictating.
-- **If the local LLM hangs mid-generation**, the status indicator may stay on "Cleaning up" until you restart the app. Your transcript is preserved and the rest of the app continues to work.
-- Cloud transcription (OpenAI Whisper API and equivalents) is not available in this release.
-- The MCP server grants read access to your entire transcript history with no per-row permission boundary. A finer-grained permission system is planned for a later release.

-## Project
-
-Lumotia — a local-first, cognitive-load-aware dictation + task-capture desktop app. Tauri 2 + Svelte 5 frontend, Rust workspace backend. Pre-alpha, daily-dogfooded on Linux/Wayland (KDE). Full product context lives in [README.md](README.md) and [docs/brief/](docs/brief/); design principles are non-negotiable and codified in [docs/whisper-ecosystem/lumotia-context.md](docs/whisper-ecosystem/lumotia-context.md).
-
-## Commands
-
-Dev launch (Vite + Tauri, with supply-chain pre-flight):
-```bash
-./run.sh                # canonical; also: npm run dev:tauri
-npm run dev:frontend    # frontend-only iteration, no Tauri
-```
-
-Install: `npm ci --ignore-scripts` (never bare `npm install` — `--ignore-scripts` blocks the npm-worm postinstall vector).
-
-Tests + checks:
-```bash
-cargo test --workspace                          # all Rust tests (220+ lib, 67 Tauri-app)
-cargo test -p lumotia-transcription             # single crate
-cargo test -p lumotia-llm <test_name>           # single test (substring match)
-cargo check --workspace --all-targets           # what CI runs
-cargo fmt --check                               # release gate
-cargo clippy --workspace --all-targets -- -D warnings  # release gate
-npm run check                                   # svelte-check, jsconfig-driven
-npm run test                                    # vitest (jsdom; *.test.ts beside source)
-npm run test -- src/lib/foo.test.ts             # single vitest file
-```
-
-Release build: `npm run tauri build`. CI builds installers on tag push.
-
-Rebrand-migration end-to-end probe (Linux only — Tauri 2 ignores `HOME` overrides on macOS):
-```bash
-cargo build -p lumotia
-scripts/dogfood-rebrand-drill.sh                # sandbox mode
-scripts/dogfood-rebrand-drill.sh --against-real-home   # refuses if lumotia data exists
-```
-
-## Architecture (the parts to internalise before editing)
-
-Three layers, strict dependency direction: **Svelte (UI) → Tauri commands (OS bridge) → Rust crates (brain)**. The MCP server (`lumotia-mcp`) is a separate read-only binary that opens the same SQLite store — Lumotia-as-primitive for external agents.
-
-Rust workspace (`crates/*` + `src-tauri/`) holds all logic. Tauri command modules in [src-tauri/src/commands/](src-tauri/src/commands/) are thin adapters and should not contain business logic. The 22 command modules map roughly 1:1 to a subsystem (audio, llm, transcription, profiles, tasks, hotkey, paste, windows, …). The utility-only modules in the same directory (`mod`, `power`, `security`) carry no `#[tauri::command]` attribute — don't add them to the invoke handler.
-
-Engine abstractions: `LocalEngine` in `lumotia-transcription` wraps both Whisper (`whisper-rs`) and Parakeet (`transcribe-rs` ONNX) behind a common `Transcriber` trait. LLM surfaces (`cleanup_text`, `decompose_task`, `extract_tasks`) in `lumotia-llm` use GBNF grammars to guarantee parseable JSON. Prompt-injection-hardened cleanup prompt lives in `lumotia-ai-formatting::llm_client::CLEANUP_PROMPT`.
-
-Storage is SQLite via `sqlx` 0.8 in `lumotia-storage`, with FTS5 for transcript search. The MCP binary opens this store read-only.
-
-### Frontend state model
-
-Svelte 5 runes (`$state`, `$derived`, `$effect`) — no Svelte 3/4 store API. State lives in [src/lib/stores/](src/lib/stores/), one file per store. The central store is [page.svelte.ts](src/lib/stores/page.svelte.ts) — transcripts, profiles, taskLists, templates, etc. are fields on it. Secondary windows (`/float`, `/viewer`, `/preview`) use named layouts (`+layout@.svelte`) to skip the main shell and run chrome-free.
-
-### Wiring contracts (enforced socially, not by the compiler)
-
-- **Every new Tauri command** must be (a) implemented in `src-tauri/src/commands/<module>.rs`, (b) registered in the invoke handler in [src-tauri/src/lib.rs](src-tauri/src/lib.rs), and (c) called from the frontend. Forgetting (b) is the most common breakage.
-- **Every Settings-visible setting** needs a type field in [src/lib/types/app.ts](src/lib/types/app.ts) and a default in [src/lib/stores/page.svelte.ts](src/lib/stores/page.svelte.ts).
-- **Every new workspace crate** needs a `description` in its `Cargo.toml`.
-- Smoke test per new command or crate module; workspace floor is "no regressions on main."
-
-## Platform notes that affect code
-
-- **Wayland is a first-class target.** Don't assume X11. The preview overlay uses `WindowTypeHint::Utility`, never steals focus, is pinned across virtual desktops, and is hidden from Alt+Tab. The paste matrix (`wtype` / `xdotool` / `ydotool` on Linux, AppleScript on macOS, SendKeys on Windows) handles the focus-race against the overlay — see [src-tauri/src/commands/paste.rs](src-tauri/src/commands/paste.rs).
-- **Linux hotkey is evdev**, not `tauri-plugin-global-shortcut`. Implemented in `lumotia-hotkey`. Requires the user to be in the `input` group; the crate surfaces this as a clear error when `/dev/input/event*` is inaccessible.
-- **`run.sh` owns Linux rendering env vars** (`LIBCLANG_PATH`, `WEBKIT_DISABLE_DMABUF_RENDERER`, `GDK_BACKEND=x11` on Wayland to dodge a webkit2gtk issue). Anything that pre-checks these in `lib.rs` is checking what the launcher set, not the user's shell.
-- **CI runs on all three OSes** (`.github/workflows/`) — Linux/macOS/Windows. macOS and Windows are CI-validated but not runtime-tested; see [KNOWN-ISSUES.md](KNOWN-ISSUES.md) for tracked gaps (App Nap on Apple Silicon, idle-inhibit on X11/Linux, sleep prevention on Windows).

-No voice, transcript, or task data leaves the machine unless the user explicitly sends it. No telemetry, no analytics, no crash-reporting service. Cleanup is **additive** — raw Whisper transcript must always be recoverable. LLM scope is narrow: transcription cleanup + task extraction only. Not a wake-word agent, not a chat UI, not a multi-provider cloud fan-out. If a change risks any of this, surface it before implementing.
-
-## v0.1 release scope (active gate)
-
-The v0.1 ship gate lives in [docs/release/v0.1-checklist.md](docs/release/v0.1-checklist.md); the UI hardening boundary is pinned in [docs/release/v0.1-ui-hardening.md](docs/release/v0.1-ui-hardening.md). All release docs live under [docs/release/](docs/release/) — use that folder as the source of truth. Before adding a feature, check the **Out of scope for v0.1** list — reopening a v0.2-flagged item moves the ship date. Garden Inbox, full Settings 7-group regroup, OpenAI Whisper API BYOK, OEM verification, Obsidian plugin, and the Phase B filter-chain refactor are all explicitly v0.2+.
-
-The release acceptance test is the 10-step tester flow (install → onboarding → record → cleanup → task → MicroSteps + timer → history search). Warm activation target: first real recording within 3 minutes of opening the app. UI hardening is a *hardening* pass, not a redesign — every item must be testable, not aesthetic.
-
-## Where to look first
-
-- Latest session context: [HANDOVER.md](HANDOVER.md), then dated handovers in [docs/handovers/](docs/handovers/).
-- Tracked limitations + per-step failure-mode catalogue: [KNOWN-ISSUES.md](KNOWN-ISSUES.md).
-- Per-platform dependency reference: [docs/dev-setup.md](docs/dev-setup.md).
-- Product/strategy framing: [docs/brief/](docs/brief/) — especially `what-lumotia-is.md`, `design-principles.md`, `target-audience.md`.
-- Active workstreams + 31-item research backlog: [docs/whisper-ecosystem/brief.md](docs/whisper-ecosystem/brief.md), `workstream-A.md`, `workstream-B.md`.
-- GPU tuning roadmap: [docs/gpu-tuning/plan.md](docs/gpu-tuning/plan.md).

-# Contributing to Lumotia
-
-## Welcome
-
-Lumotia is a single-developer-led, AI-assisted, human-directed indie app. Jake Sames at CORBEL defines the product, sets the privacy model, writes the tests that matter, and ships through a repeatable quality gate. AI coding tools are used during implementation. Every release is dogfood-tested, every release ships a known-limitations document, and every release has an audit trail in the git log. Read `docs/release/how-lumotia-is-built.md` to understand the trust model before contributing.
-
-## What we are looking for in v0.1
-
-Bug reports and tester feedback are the most valuable contributions right now. **New feature work is paused until v0.2** — the scope is locked per `docs/release/v0.1-checklist.md`. Reopening a v0.2-flagged item moves the ship date. If you have a feature idea, open a Discussion rather than a PR.
-
-## How to file a bug
-
-Open an issue using the **Bug report** template. The template walks you through version, platform, steps to reproduce, and expected vs actual behaviour.
-
-Please attach a diagnostic bundle — it speeds up triage significantly. Generate one from **Settings → Help → Generate diagnostic bundle**. The bundle never includes audio or transcript content; it contains logs, system info, and redacted preferences only.
-
-## How to file v0.1 tester feedback
-
-Open an issue using the **v0.1 Tester feedback** template. It covers the structured questions from the tester-onboarding-kit: cold-setup pass, warm-activation pass, confusion points, breakage, task-extraction quality, and whether you would use it again.
-
-If you followed the onboarding kit, you already have the answers. The template takes about 5 minutes to fill in.
-
-## How to submit a PR
-
-Small, focused changes only. The PR template has a checklist — run every gate green before submitting.
-
-Before submitting:
-
-- `cargo test --workspace` green
-- `cargo fmt --check` clean
-- `cargo clippy --workspace --all-targets -- -D warnings` clean
-- `npm run check` 0 errors / 0 warnings
-- `npm run test` green
-- `scripts/dogfood-rebrand-drill.sh` 8/8 (if you touched migration or data-directory logic)
-- Manual UI walk-through (if you touched the frontend)
-
-**Architectural changes require a Discussion first.** Opening a PR that restructures crates, reorganises commands, or changes the storage schema without prior alignment wastes both our time.
-
-## Local dev setup
-
-```bash
-npm ci --ignore-scripts   # never bare npm install — --ignore-scripts blocks postinstall vectors
-./run.sh                  # canonical dev launch (Vite + Tauri, with supply-chain pre-flight)
-npm run dev:frontend      # frontend-only iteration, no Tauri
-```
-
-Per-platform dependencies (WebKit, LLVM, Rust toolchain, evdev headers) are documented in `docs/dev-setup.md`. The Rust toolchain is pinned in `rust-toolchain.toml` — you do not need to manage it manually.
-
-## Code of conduct
-
-This is a calm, professional project. No harassment, no personal attacks, no bad-faith contributions. The maintainer is one person — please be patient on response times. Issues and PRs that are rude or dismissive will be closed without comment.
-
-## Licence
-
-Lumotia is licensed under **AGPL-3.0-or-later**. By submitting a pull request, you agree that your contribution is offered under the same licence. If that does not work for you, please say so before putting in the work.

 ### Platform-aware window chrome (Linux fix)
 **Root cause:** Tauri v2 frameless `decorations: false` on KDE Wayland + webkit2gtk does not honour diagonal corner resize (collapses `NorthEast` etc. to a single axis via GTK's `gtk_window_begin_resize_drag`), and `data-tauri-drag-region` adds noticeable drag latency. Setting `setPointerCapture` ahead of `startResizeDragging` does not help once the compositor has taken over the pointer grab. Verified via Context7 docs + Codex diagnosis — Linux frameless is a known-fragile path.

 - Linux uses **native KWin/Mutter decorations**. `src-tauri/tauri.linux.conf.json` overlays `decorations: true` + full main window config (title, sizes) — overlays **replace** the windows array, so every field must be present, not just the delta. `src-tauri/src/commands/windows.rs` uses `cfg!(target_os = "linux")` to set decorations per window.
 - macOS / Windows keep custom chrome. `src/lib/utils/osInfo.js` `isLinux()` gates `<Titlebar>` and `<ResizeHandles>` via `useCustomChrome = $state(false)`; flips to `!isLinux()` after `loadOsInfo()` resolves.
 - Dueling drag-region handlers removed across Titlebar, float page, viewer page — everywhere a manual `startDragging()` lives, the `data-tauri-drag-region` attribute was deleted (they're alternatives per Tauri docs, not combinable).

-## 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.

-                    GNU AFFERO GENERAL PUBLIC LICENSE
-                       Version 3, 19 November 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-our General Public Licenses are intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
-
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
-
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If your software can interact with users remotely through a computer
-network, you should also make sure that it provides a way for users to
-get its source.  For example, if your program is a web application, its
-interface could display a "Source" link that leads users to an archive
-of the code.  There are many ways you could offer source, and different
-solutions will be better for different programs; see section 13 for the
-specific requirements.
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU AGPL, see

-### Installing npm dependencies
-
-Use `npm ci --ignore-scripts` rather than bare `npm install`. `--ignore-scripts` blocks the postinstall script vector that npm-worm attacks (Shai-Hulud, mini-Shai-Hulud) rely on. `ci` installs strictly from `package-lock.json`, refusing to mutate the lockfile silently.
-
-```bash
-npm ci --ignore-scripts
-```
-
-`run.sh` runs `npm audit signatures` automatically whenever `package-lock.json` is newer than the last successful audit, and refuses to launch on signature mismatch. Skip with `LUMOTIA_SKIP_AUDIT=1` for offline dev.

-//! flagged in the hotkey listener:

-//! - **Race-1** — orphaned per-device listener tasks after `stop()`.
-//!   Coverage: `listener_stop_drops_internal_senders` — exercises the
-//!   only side-effect we can observe through the public API. After
-//!   `stop()` every internal device-listener task must drop its
-//!   `mpsc::Sender<HotkeyEvent>` clone, which we detect by asserting
-//!   that the receiving end's `recv()` returns `None`.
-//!
-//! - **Race-2** — leaked forwarder task on reconfigure. Coverage:
-//!   `reconfigure_does_not_leak_forwarder` — simulates the exact pattern
-//!   the Tauri command layer uses (listener + forwarder pair), confirms
-//!   that after a reconfigure the OLD forwarder has joined and only the
-//!   new one is consuming events.
-//!
-//! - **Race-extra (TOCTOU)** — see `// TODO(test):` in
-//!   `crates/hotkey/src/linux.rs`. Exercising the TOCTOU window
-//!   deterministically requires faking the evdev::Device::open path,
-//!   which the crate does not currently expose. The fix is closed by

-//! End-to-end migration test for the Magnotia -> Lumotia rebrand.
-//!
-//! The in-crate unit tests in `crates/core/src/paths.rs` prove that the
-//! migration copies bytes and renames files correctly, but they don't
-//! verify that the resulting `lumotia.db` is *openable* by
-//! `lumotia-storage`. A byte-perfect copy with a torn SQLite header,
-//! a stale WAL pointer, or a row count off by one would still pass
-//! those tests. This integration test closes that gap by:
-//!
-//!   1. Seeding a real on-disk `magnotia/magnotia.db` via the public
-//!      `lumotia_storage::init` API (which runs every schema migration
-//!      head-to-tail). A real transcript row is inserted via
-//!      `insert_transcript`, then the pool is dropped to flush + close.
-//!   2. Running the rebrand migration via
-//!      `lumotia_core::paths::migrate_legacy_data_dir_with_pairs` with
-//!      the synthesised (legacy, target) pair.
-//!   3. Re-opening the migrated `lumotia/lumotia.db` via `init`
-//!      (which re-runs migrations — they must be no-ops against the
-//!      already-migrated schema) and querying for the inserted
-//!      transcript by id.
-//!
-//! If any of the three steps fails — rename, reopen, or query — the
-//! migration is unsafe to ship even though the unit tests pass.

-# Frontend (Slice 01)
-
-> **Where you are:** [Architecture map](../README.md) → Frontend
-
-**Plain English summary.** This slice is everything the user sees. It is a Svelte 5 single page app, served by SvelteKit in SPA mode, hosted inside Tauri's webview. It owns four windows (main, tasks float, transcript viewer, transcription preview overlay), seven page modules switched by an in memory router store, around thirty reusable components, ten reactive stores, and the design system tokens. The frontend never touches the filesystem, audio, models or the LLM directly. Everything that crosses the WebView boundary goes through `invoke()` (calling Rust commands) or Tauri events. If you delete this slice, you delete the entire user surface but keep the engine.
-
-## At a glance
-
-- **Path:** `src/`
-- **Total LOC counted:** about 17 200 (583 `app.css` + 2 740 routes + 6 230 pages + 3 174 components + 4 085 stores/utils/types + ~ 2 360 design system + 130 misc).
-- **File counts:** 7 pages, 25 components, 10 stores, 1 action, 16 utils, 1 type module, 3 locales, 4 routes (root + float/viewer/preview), 20 design system preview HTMLs, 3 design system JSX kits.
-- **Frameworks:** Svelte 5 (runes mode), SvelteKit 2.58, `@sveltejs/adapter-static` with `index.html` fallback (SPA), Vite 6, Tailwind v4 via `@tailwindcss/vite`, svelte-i18n 4, lucide-svelte for icons.
-- **Tauri SDK touchpoints:** `@tauri-apps/api` (core invoke, event, window) plus `plugin-autostart`, `plugin-dialog`, `plugin-global-shortcut`, `plugin-notification`, `plugin-opener`. SSR is disabled (`src/routes/+layout.js`) so the whole tree is client side only.
-- **Persistence used directly by frontend:** `localStorage` for `lumotia_settings`, `lumotia_profiles`, `lumotia_task_lists`, `lumotia_templates`, `lumotia_locale`, plus a small handoff key for the viewer window. Preferences additionally persist via Tauri (`save_preferences`).
-- **Build commands:** `npm run dev` (`svelte-kit sync && vite dev`), `npm run build`, `npm run check` (svelte-check using `jsconfig.json`).

-- [Windows and routes](windows-and-routes.md). The four Tauri windows, the SvelteKit routes that back them, the `+layout@.svelte` break, and how the shell decides between custom chrome and native decorations.
-- [Pages overview](pages-overview.md). Index of the seven pages routed by `page.current`, and the `/float`, `/viewer`, `/preview` route pages.

-## How this slice connects to others
-
-**In (frontend depends on Tauri runtime, slice 02).**
-
-- Sixty plus distinct `invoke()` commands. Full list with caller in [frontend-tauri-bridge.md](frontend-tauri-bridge.md).
-- Tauri events listened to: `model-download-progress`, `parakeet-download-progress`, `lumotia:llm-download-progress`, `lumotia:hotkey-pressed`, `lumotia:open-wind-down`, `lumotia:preferences-changed`, `task-window-focus`, `preview-listening`, `preview-cleanup`, `preview-hide`, plus drag drop (`tauri://drag-drop`, `tauri://drag-enter`, `tauri://drag-leave`).
-- Window APIs: `getCurrentWindow().minimize() / toggleMaximize() / setPosition() / label`.
-- Plugin imports loaded lazily: `@tauri-apps/plugin-global-shortcut`, `@tauri-apps/plugin-dialog`.
-
-**Out (frontend triggers behaviour back into the runtime).**
-
-- DOM `CustomEvent` bus on `window` carries internal traffic (`lumotia:start-timer`, `lumotia:toggle-recording`, `lumotia:task-completed`, etc). The Rust side does not listen to these; they are intra frontend.
-- Tauri `emit()` is used for `lumotia:preferences-changed` only, to fan preference updates across windows.
-- Multi window orchestration: pages call `open_task_window`, `open_viewer_window`, `open_preview_window` to ask Rust to spawn secondary webviews.
-
-**Other slices that read frontend conventions.**
-
-- Slice 02 (Tauri runtime) emits the events listed above and registers commands the frontend invokes.
-- Slice 03 (audio + transcription) ships partial results via a `Channel` (Tauri 2 typed channel) opened in `DictationPage`.
-- Slice 04 (LLM, formatting, MCP) emits `lumotia:llm-download-progress` and `cleanup_transcript_text_cmd` results consumed by Dictation.
-- Slice 05 (storage, hotkey, build) supplies `add_transcript`, `delete_transcript`, profiles, tasks and the evdev hotkey backend.

-## Open questions, debt, drift, dead code
-
-1. **`src/lib/Sidebar.svelte` lives outside `components/`.** Every other reusable Svelte module is under `src/lib/components/`. The sidebar is the only sibling of those folders. Cosmetic but it surprises contributors.
-2. **Two parallel theme systems.** `settings.theme` (string `"Light"`/`"Dark"`/`"System"`) coexists with `preferences.theme` (`"light"`/`"dark"`/`"system"`). `+layout.svelte:61-68` and `float/+layout@.svelte` both run a "legacy → new" migration `$effect` every time. The legacy pathway should be retired.
-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 `lumotia:preferences-changed` Tauri event. Inconsistent. Settings sync via `storage` is fragile because it only fires on cross document writes.
-7. **`shims.d.ts` next to the lib root.** Single shim file at `src/lib/shims.d.ts`. Worth verifying it is still needed (Svelte 5 + SvelteKit ship most ambient types now).
-8. **`design-system/ui_kits/`** contains JSX components and an HTML index. They are reference, not live, and should not import from the runtime tree. Confirm the build excludes them.
-9. **`speaker.svelte.ts` is ten lines.** A near empty store. Used by `SpeakerButton.svelte`. Consider folding into a util if it never grows.
-10. **CSS variable `--font-size-transcript` is set on `body` from `+layout.svelte` but `preferences` already sets `--font-size-body` and `--transcript-font-size`.** Three knobs for transcript text size in different stores. Drift between `settings.fontSize` and `preferences.accessibility.transcriptSize` is likely.
-11. **i18n coverage is thin.** Each locale has 19 lines. svelte-i18n is wired but most strings remain hardcoded. Treat as a stub.
-12. **Tailwind v4 has no standalone config file.** All theming lives in `app.css` `@theme`. There is no `tailwind.config.{js,ts}`. Mention this so contributors do not waste time looking.
-13. **`docs/architecture-map/01-frontend/` was empty before this pass.** Reciprocal slice indexes (02 to 05) need updating to point here.

-# Actions, utils, types
-
-> **Where you are:** [Architecture map](../README.md) → [Frontend](README.md) → Actions, utils, types
-
-**Plain English summary.** Helpers that are not components and not state. The single Svelte action (`bionicReading`), 16 utility modules under `src/lib/utils/`, and the `app.ts` type module that everyone imports.
-
-## Actions
-
-### `src/lib/actions/bionicReading.ts` (74 LOC)
-
-Svelte action that toggles "bionic reading" rendering on a node. Walks the text nodes via `TreeWalker`, replaces them with bolded prefix + plain suffix spans. A `MutationObserver` reapplies on text changes (disconnects while mutating to avoid infinite loop). `stripBionic` undoes by unwrapping `<b>` tags and normalising adjacent text nodes.
-
-Used in DictationPage and the viewer. Wired to `preferences.accessibility.bionicReading`.
-
-## Utils
-
-### `runtime.ts` (45 LOC)
-
-Exports `hasTauriRuntime()`. Probes for `window.__TAURI_INTERNALS__` or `window.isTauri` to short circuit Tauri calls in browser preview mode. Used everywhere as the gate before `invoke()`.
-
-### `osInfo.ts` (110 LOC)
-
-Caches OS info via `invoke("os_info")` (or similar; check `lib.rs`). Exposes `loadOsInfo`, `isMac`, `isLinux`, `modKeyLabel` synchronously after `loadOsInfo` resolves. Drives whether the shell renders custom or native chrome.
-
-### `errors.ts` (8 LOC)
-
-`errorMessage(e)` returns a string from `Error | unknown`. Tiny.
-
-### `storage.ts` (8 LOC)
-
-`parseStoredJson<T>(key, fallback)` wraps `JSON.parse(localStorage.getItem(key))` with try/catch. Used by `settingsMigrations`, `page.svelte.ts`, and the viewer handoff.
-
-### `settingsMigrations.ts` (134 LOC)
-
-Versioned migrations for `lumotia_settings`. Holds `CURRENT_SETTINGS_VERSION = 1`. Envelope shape: `{ version: number, data: T }`. Reads bare unversioned blobs as v0. `loadSettingsWithMigration(key, defaults)` walks the chain and toasts on corruption.
-
-### `frontmatter.ts` (148 LOC)
-
-Builds YAML frontmatter for transcript markdown export.
-
-- `deriveAutoTags(text, profile)`. Heuristic auto tags.
-- `buildFrontmatter(transcript)`. Returns the YAML block.
-- `buildMarkdown(transcript)`. Joins frontmatter + body.
-- `normaliseTag(s)`. Lowercase, replace whitespace.
-
-### `saveMarkdown.ts` (132 LOC)
-
-Save dialog + write file dance. `suggestedFilename(item)` builds `<slug>-<YYYY-MM-DD>.md`. `saveTranscriptAsMarkdown(item)` opens `@tauri-apps/plugin-dialog`, then writes via `invoke`. `exportTranscriptsToDir(items)` for bulk export.
-
-### `export.ts` (125 LOC)
-
-Generic export helpers used by DictationPage and FilesPage. Format choice: plain text, markdown, JSON. Falls through to clipboard or save dialog.
-
-### `taskExtractor.ts` (224 LOC)
-
-`extractTasks(text)` uses regex heuristics for "TODO:", "Action:", "I need to ...", numbered lists, etc. Falls back when LLM extraction is unavailable.
-
-### `textMeasure.ts` (166 LOC)
-
-Canvas-based pre-wrap text measurement. `measurePreWrap(text, font, lineHeight, width)` returns the rendered height. `clampTextLines(text, n)` trims to N lines plus ellipsis. Used by HistoryPage virtual scroll and DictationPage textarea sizing.
-
-### `accessibilityTypography.ts` (41 LOC)
-
-Reads `--font-family-body`, `--font-size-body`, `--line-height-body`, `--letter-spacing-body` from `<html>` and returns numeric values. `pretextFontShorthand`, `bodyPretextLineHeight`, `transcriptPretextFont`, `transcriptPretextLineHeight` are the public helpers.
-
-### `virtualList.ts` (49 LOC)
-
-`buildCumulativeOffsets(heights)` and `findVisibleRange(offsets, scrollTop, viewportHeight, overscan)`. Pure. Used by HistoryPage and `VirtualSegmentList`.
-
-### `time.ts` (46 LOC)
-
-`pad(n)`, `formatTime(seconds)`, `formatDuration(seconds)`, `formatTimestamp(iso)`. Display helpers.
-
-### `sounds.ts` (101 LOC)
-
-Loads the start/stop/complete cue sounds via `<audio>` and exposes `playStartCue()`, `playStopCue()`, `playCompleteCue()`. Volume from `settings.soundCueVolume`. Honours `settings.soundCues` flag.
-
-### `hotkeyValidity.ts` (149 LOC)
-
-Validates a hotkey combo against per-OS rules (no Cmd alone on macOS, no single letters, etc). Used by `HotkeyRecorder.svelte`.
-
-### `constants.js` (30 LOC)
-
-The shared scalars:
-- Timing: `FEEDBACK_TIMEOUT_MS`, `HOTKEY_FEEDBACK_MS`, `HISTORY_MAX_ENTRIES = 100`, `MAX_PCM_SAMPLES = 4_800_000` (5 min @ 16 kHz), `SIDEBAR_MAX_TASKS = 30`, `CHUNK_INTERVAL_MS = 3000`, `MIN_CHUNK_SAMPLES = 8000`.
-- Buckets: `BUCKET_COLORS`, `BUCKET_DOT_COLORS` (`inbox` / `today` / `soon` / `later`).
-- Effort: `EFFORT_LABELS`, `EFFORT_ORDER`.
-- Playback: `PLAYBACK_SPEEDS = [0.5, 1, 1.5, 2, 3, 5]`.
-
-Note: this is `.js`, not `.ts`. Other utils are `.ts`.
-
-## Types
-
-### `src/lib/types/app.ts` (408 LOC)
-
-Single source of truth for shared shapes. Contains:
-- `PageState`, `SettingsState`, `Preferences`, `AccessibilityPreferences`.
-- `Profile`, `Template`, `TaskList`, `TaskBucket`, `TaskEntry`, `TaskDraft`, `TaskUpdate`, `TaskDto`, `EnergyLevel`.
-- `TranscriptDto`, `TranscriptEntry`, `TranscriptWriteEntry`, `TranscriptMetaPatch`, `Segment`, `ViewerSegment`.
-- `DailyCompletionCount`, `ToastSeverity`, `FontFamily`, `ReduceMotion`.
-
-### `src/lib/shims.d.ts`
-
-Single ambient declaration file. Worth verifying the contents are still needed (Svelte 5 + SvelteKit ship most ambient types now). README debt note 7.
-
-## Watch outs
-
-- `constants.js` is JS, not TS. If you migrate, the JSDoc shapes in `BUCKET_COLORS` need to align with Tailwind class strings; type-only objects still need a runtime export.
-- `taskExtractor.ts` is a regex heuristic. The LLM path (`extract_tasks_from_transcript_cmd`) is the better signal; the heuristic is the offline fallback.
-- `osInfo.ts` caches forever. If you need to handle a hot OS detection retry (you should not), invalidate the cache yourself.
-- `textMeasure.ts` uses an offscreen `<canvas>`. Costs are real for long transcripts; results are cached per (text, font, line-height, width) tuple in HistoryPage.
-- `frontmatter.ts` and `saveMarkdown.ts` overlap. The former produces the body; the latter handles the I/O. Keep them split.

-# App shell and styling
-
-> **Where you are:** [Architecture map](../README.md) → [Frontend](README.md) → App shell and styling
-
-**Plain English summary.** Where the visual chrome and CSS plumbing live. `app.html` is the SvelteKit document. `app.css` carries the Tailwind v4 import, the `@theme` token block, the brand `@font-face` declarations, the sensory zones, and the accessibility CSS variables. There is no separate `tailwind.config.{js,ts}`; Tailwind v4 is configured entirely in `app.css`. Fonts ship from `src/fonts/` (bundled by Vite) and `static/fonts/` (served as-is).
-
-## At a glance
-
-- **Path:** `src/app.html`, `src/app.css`, `src/app.d.ts`, `src/fonts/`, `src/assets/`, `static/`.
-- **LOC:** 13 (`app.html`) + 583 (`app.css`) + 8 (`app.d.ts`).
-- **Frameworks:** Tailwind v4 via `@tailwindcss/vite`. No PostCSS config. No standalone Tailwind config file.
-- **Adapter:** `@sveltejs/adapter-static` with `index.html` fallback (SPA, `svelte.config.js`).
-
-## What's in here
-
-### `src/app.html` (13 LOC)
-
-Standard SvelteKit document. Sets `lang="en"`, charset, viewport, favicon, title (`Lumotia`), and applies `data-sveltekit-preload-data="hover"` on `<body>`. The body content is wrapped in `<div style="display: contents">` so the SvelteKit-injected children render inline.
-
-### `src/app.d.ts` (8 LOC)
-
-Ambient declaration extending `Window` with `__TAURI_INTERNALS__` and `isTauri` so `utils/runtime.ts` typechecks.
-
-### `src/app.css` (583 LOC)
-
-Layered:
-1. `@import "tailwindcss"` (Tailwind v4 entry).
-2. `@font-face` for Lexend, Atkinson Hyperlegible Next, OpenDyslexic, JetBrains Mono, Instrument Serif Italic. URLs use root-absolute paths (`/fonts/...`) served from `static/fonts/` by Vite.
-3. `@theme` token block. Sets the design tokens that Tailwind v4 picks up as utility classes:
-   - Colour tokens: `--color-bg`, `--color-bg-raised`, `--color-text`, `--color-text-secondary`, `--color-text-tertiary`, `--color-accent`, `--color-warning`, `--color-success`, `--color-border`, `--color-border-subtle`, `--color-hover`, `--color-nav-active`, plus a sensory-zone palette family.
-   - Typography tokens: `--font-display`, `--font-body`, `--font-mono`, plus `--font-size-*` and `--line-height-*`.
-   - Motion tokens: `--duration-ui`, `--duration-fast`, `--duration-slow`. Easing tokens for `cubic-bezier` curves.
-   - Shadow tokens: `--shadow-accent-md`, `--shadow-accent-glow`, etc.
-4. Sensory-zone overrides keyed on `[data-zone="..."]` on `<html>`. Switches token values to dim, focus, etc.
-5. Theme overrides keyed on `[data-theme="dark"]` and `[data-theme="light"]`. The `preferences` store writes both `data-theme` and `data-zone`.
-6. Accessibility variables on `<html>`: `--font-family-body`, `--font-size-body`, `--letter-spacing-body`, `--line-height-body`. Set by the `preferences` store via `applyToDOM()`.
-7. Base styles: `body` background, font, body font-family bound to the variable, scrollbar styling, focus ring.
-8. Utility classes for grain texture (`.grain` uses the noise asset under `assets/grain.svg`), CRT-style transcript surface, etc.
-9. Animations: `@keyframes fade-in`, `@keyframes pulse`, etc. Reduced motion guard at the bottom (`@media (prefers-reduced-motion: reduce)`).
-
-### `src/fonts/` (bundled woff2)
-
-- `atkinson-hyperlegible-next.woff2`
-- `instrument-serif-italic.woff2`
-- `jetbrains-mono.woff2`
-- `lexend-variable.woff2`
-- `opendyslexic.woff2`
-
-Bundled by Vite (referenced from `app.css` via `/fonts/...` paths that Vite resolves). The same files live in `static/fonts/` for the static-served path. Confirm whether both paths are required; if Vite handles font copying, `static/fonts/` may be redundant.
-
-### `src/assets/`
-
-- `grain.svg`. Noise texture used by the `.grain` utility class.
-- `waveform-mark.svg`. Brand glyph.
-- `wordmark.svg`. Brand wordmark.
-
-### `static/`
-
-Served as-is from the webview root.
-
-- `favicon.png`. Site favicon.
-- `fonts/`. Same five woff2 files as `src/fonts/`. Likely the source of `app.css /fonts/...` URLs.
-- `pcm-processor.js`. AudioWorklet processor (slice 02 owns the integration). 32-line file that converts microphone input to int16 PCM frames and posts them up.
-- `textures/grain.png`. PNG version of the grain texture.
-- `svelte.svg`, `tauri.svg`, `vite.svg`. SvelteKit defaults; technically unused. Candidate for removal.
-
-## How preferences map to the DOM
-
-| Preference | DOM target |
-|---|---|
-| `theme` ("light" / "dark" / "system") | `data-theme` on `<html>`. `system` resolves to OS preference at apply time. |
-| `zone` ("default" / ...) | `data-zone` on `<html>`. |
-| `accessibility.fontFamily` ("lexend" / "atkinson" / "opendyslexic") | `--font-family-body` CSS variable on `<html>`. |
-| `accessibility.fontSize` | `--font-size-body` (pixels). |
-| `accessibility.letterSpacing` | `--letter-spacing-body` (em). |
-| `accessibility.lineHeight` | `--line-height-body` (unitless). |
-| `accessibility.bionicReading` | `<html data-bionic-reading="true|false">`. The `bionicReading` action reads this. |
-| `accessibility.reduceMotion` | `<html data-reduce-motion="reduce|no-preference|system">`. Pairs with the `prefers-reduced-motion` media query. |
-
-Plus the legacy `settings.fontSize` writes `--font-size-transcript` on `<body>` directly (`+layout.svelte:204`). That is separate from `accessibility.fontSize`.
-
-## Tailwind v4 setup
-
-- Installed via `@tailwindcss/vite` in `vite.config.js:3`.
-- Entry: `src/app.css` line 1, `@import "tailwindcss"`.
-- Tokens declared inline via `@theme` blocks in `app.css`.
-- No `tailwind.config.{js,ts}` exists. Do not look for one.
-- Class scanning: Tailwind v4 scans the source tree by default. Custom paths can be configured with `@source` directives if needed.
-
-## Watch outs
-
-- **Two font sources.** `src/fonts/` (Vite bundled) and `static/fonts/` (raw served). Confirm whether both are needed; redundancy bloats the bundle.
-- **Mirror file `src/design-system/colors_and_type.css`** must be updated whenever `app.css` `@theme` changes. There is no automated check.
-- **`prefers-reduced-motion` honoured by CSS** but JS animations (e.g. `CompletionSparkline`'s stagger) are guarded in component code, not via the media query alone.
-- **Tailwind v4 `@theme` is class-scanning sensitive.** If you put utility class strings inside conditional template literals that Tailwind cannot see at scan time, they will not be generated.
-- **Removing default SvelteKit assets** (`static/svelte.svg`, `vite.svg`, `tauri.svg`) requires confirming nothing references them in `app.html` or `README.md`.
-- **`pcm-processor.js`** is a static asset because AudioWorklet processors must be served from a same-origin URL. Bundling it through Vite would break the worklet registration. Leave it in `static/`.

-# Components
-
-> **Where you are:** [Architecture map](../README.md) → [Frontend](README.md) → Components
-
-**Plain English summary.** All 25 reusable Svelte 5 components, plus `Sidebar.svelte` which is the only component that lives at `src/lib/Sidebar.svelte` rather than under `src/lib/components/`. Grouped by what they do. Where a component is mounted directly by the shell (`+layout.svelte`), that is called out.
-
-## At a glance
-
-- **Path:** `src/lib/components/` (25 files), plus `src/lib/Sidebar.svelte`.
-- **LOC:** 3 174 (components) + 178 (sidebar) = 3 352.
-- **Conventions:** Svelte 5 runes (`$state`, `$props`, `$derived`, `$effect`). Tailwind v4 utility classes. CSS variables for design tokens. Lucide icons at 16/20/24px with `aria-label` next to or instead of the glyph.
-
-## Shell mounts (always present)
-
-| Component | LOC | Path | Purpose |
-|---|---|---|---|
-| `Sidebar` | 178 | `src/lib/Sidebar.svelte` | Left nav. Switches `page.current`. Collapsed mode shows tooltips. Renders task badge from `tasks.length`. |
-| `Titlebar` | 80 | `src/lib/components/Titlebar.svelte` | Custom window chrome for non Linux (frameless windows). Min/max/close + drag area + sidebar aligned spacer. |
-| `ToastViewport` | 143 | `src/lib/components/ToastViewport.svelte` | Bottom right toast stack. Reads from the global `toasts` store. Honours `prefers-reduced-motion`. |
-| `ResizeHandles` | 67 | `src/lib/components/ResizeHandles.svelte` | Invisible 5 px margins for frameless resize. Linux uses native, so `+layout.svelte` suppresses this. |
-| `FocusTimer` | 298 | `src/lib/components/FocusTimer.svelte` | Floating top right SVG progress ring. Listens for `lumotia:start-timer` window events and delegates to the focus timer store. Cancel hover, success flourish. Hidden on float and viewer windows by URL probe. |
-| `MorningTriageModal` | 356 | `src/lib/components/MorningTriageModal.svelte` | Phase 5 modal. Self gated on `settings.ritualsMorning` and time of day. Mounted globally so it appears over any page. |
-| `TaskSidebar` | 97 | `src/lib/components/TaskSidebar.svelte` | Optional right side dock that appears when `page.taskSidebarOpen`. Quick add input, top tasks, link out to the full Tasks page. |
-
-## Settings building blocks
-
-| Component | LOC | Purpose |
-|---|---|---|
-| `SettingsGroup` | 86 | Native `<details>` based progressive disclosure with animated chevron. Handler hooks (`onopen`) are used by SettingsPage to lazy probe expensive state (model lists, paste backends, etc). |
-| `Toggle` | 98 | iOS style toggle. ARIA switch role. |
-| `SegmentedButton` | 19 | Tiny segmented switch with ARIA radio role. |
-| `HotkeyRecorder` | 217 | Captures a key combo. Uses `utils/hotkeyValidity.ts` to check the combo before persisting. |
-| `ZonePicker` | 36 | Sensory zone (default / focus / dim / etc) picker that maps to a `data-zone` attribute on `<html>`. |
-| `AccessibilityControls` | 112 | Font family, font size, letter spacing, line height, reduce motion, bionic reading. Writes via `updateAccessibility`. |
-| `ImplementationRulesEditor` | 266 | Edits the implementation intentions list ("when X happens, do Y"). Persists via the `implementationIntentions` store. |
-| `ModelDownloader` | 112 | Standalone download panel used inside Dictation when no model is loaded. Subscribes to `model-download-progress`. |
-
-## Card chrome and empty states
-
-| Component | LOC | Purpose |
-|---|---|---|
-| `Card` | 35 | Generic container. Border, padding, optional header. The page level "block" primitive. |
-| `EmptyState` | 22 | Centred icon + title + body slot. Used widely. |
-| `UnicodeSpinner` | 30 | ASCII spinner used while probing or downloading. |
-
-## Tasks
-
-| Component | LOC | Purpose |
-|---|---|---|
-| `WipTaskList` | 153 | Renders task rows with energy chips, completion checkbox, expansion to show micro steps, and a "start focus timer" button (dispatches `lumotia:start-timer`). |
-| `MicroSteps` | 310 | Per task expansion: nudge bus integration, micro step suggestions from the LLM (`lumotia:microstep-generated`), step completion (`lumotia:step-completed`), per task implementation rules. |
-| `EnergyChip` | 106 | Low/medium/high energy selector. Used on task rows and in TasksPage quick add. |
-| `CompletionSparkline` | 92 | 7 day completion bar chart. Animated entrance with 30 ms stagger, respects `prefers-reduced-motion`. Reads from `recentCompletions` store. |
-| `VisualTimer` | 33 | Compact visual timer pill used inside MicroSteps and the float window. |
-
-## Transcripts
-
-| Component | LOC | Purpose |
-|---|---|---|
-| `VirtualSegmentList` | 234 | Virtualised scroll for transcript segments in the viewer window. Uses `utils/virtualList.ts` and `utils/textMeasure.ts` to compute per row heights from current preferences. |
-| `SpeakerButton` | 112 | Trigger TTS playback for a chunk of text. Uses `tts_speak`. Reads from the `speaker` store to debounce concurrent requests. |
-| `LlmStatusChip` | 60 | Pill in the sidebar/dictation surface showing LLM state (idle, generating, downloading, unavailable). Reads `llmStatus` store. |
-

-- `WipTaskList`, `MicroSteps`, `EnergyChip`, `CompletionSparkline`: TasksPage and `WipTaskList` reused inside the float window.
-- `VirtualSegmentList`: viewer/+page.svelte.
-- `SpeakerButton`: DictationPage, viewer.
-- `LlmStatusChip`: Sidebar, DictationPage.
-- `UnicodeSpinner`: FirstRunPage, SettingsPage.
-- `VisualTimer`: MicroSteps, float window.
-
-## Watch outs
-
-- `Sidebar.svelte` lives outside `components/`. README debt note 1.
-- `Titlebar` reads `settings.sidebarCollapsed` to mirror the spacer width. Animation timing is driven by `--duration-ui`.
-- `MorningTriageModal` is heavy (356 LOC). Self gates internally; do not move the gate elsewhere or you will pay its cost on every paint.
-- `FocusTimer` detects "secondary window" by URL prefix. If you add a fifth window, update the probe.
-- `CompletionSparkline` animations are the only place that uses CSS keyframes for entrance. Honour reduced motion.
-- Many components receive props with `let { foo = default } = $props();` (Svelte 5 idiom). The minimal `Card`, `EmptyState`, `Toggle`, `SegmentedButton` are good reading order for understanding the runes idiom on this codebase.

-# Design system
-
-> **Where you are:** [Architecture map](../README.md) → [Frontend](README.md) → Design system
-
-**Plain English summary.** Reference material. The runtime styles live in `src/app.css`. Everything under `src/design-system/` is brand documentation, preview pages, JSX UI kits, and ground truth source for the lumotia-design Claude skill. None of it is imported by the runtime SvelteKit app.
-
-## At a glance
-
-- **Path:** `src/design-system/`
-- **Files:**
-  - `README.md`. Brand and content rules. (Lumotia by CORBEL.)
-  - `SKILL.md`. lumotia-design skill manifest (`user-invocable: true`). The skill copies assets out and writes throwaway HTML or production code on demand.
-  - `colors_and_type.css`. Mirror of the runtime `@theme` tokens for buildless preview pages. Intentional duplication, kept in sync by hand.
-  - `preview/`. 20 buildless HTML spec cards.
-  - `ui_kits/`. JSX recreations (`DictationPage.jsx`, `OtherPages.jsx`, `Sidebar.jsx`) plus an `index.html` and a README.
-
-## What's in here
-
-### `colors_and_type.css`
-
-Mirrors `src/app.css` `@font-face` declarations and (typically) the `@theme` token block, with relative `fonts/...` URLs so preview HTML can render without going through Tailwind/Vite. The file's banner comment is explicit:
-
-> When app.css @theme changes, mirror the change here. There is no automated sync; intentional duplication keeps the preview pages buildless.
-
-### `preview/` (20 HTML files)
-
-Each renders one slice of the system:
-- Brand: `brand-icons.html`, `brand-wordmark.html`.
-- Colour: `colors-accent.html`, `colors-semantic.html`, `colors-surfaces.html`, `colors-text.html`, `colors-zones.html`.
-- Components: `components-buttons.html`, `components-cards.html`, `components-empty-states.html`, `components-inputs.html`, `components-nav.html`, `components-toasts.html`.
-- Spacing and motion: `spacing-motion.html`, `spacing-radii.html`, `spacing-scale.html`, `spacing-shadows.html`.
-- Type: `type-body.html`, `type-headings.html`, `type-transcript-mono.html`.
-
-These are static. Open in any browser.
-
-### `ui_kits/` (JSX, reference only)
-
-Three `.jsx` files plus `index.html` and a README. Reproduce the desktop pages in JSX so prototypes can be built outside the Tauri shell. The README inside ui_kits explains how to use them. They are not imported anywhere from the SvelteKit app.
-
-### Brand language (from README.md)
-
-- Built for the noise allergic. Solarpunk-as-posture, AI-minimisation, ground truth + warmth.
-- Iconography: Lucide, 2 px stroke. 16 px nav, 20 px features, 24 px primary actions. Always paired with a label except OS titlebar controls.
-- Transparency + blur used sparingly: collapsed-sidebar tooltips, float window backdrop, accent-subtle 6% tint. No glassmorphism.
-
-## Why it lives in `src/`
-
-The design system files sit under `src/` so the lumotia-design skill (which runs from this repo) can read ground-truth Svelte source from `lumotia-source/` (a sibling import). The runtime build does not include this folder; it is a reference root.
-
-## Watch outs
-
-- Tokens in `colors_and_type.css` and `app.css` `@theme` can drift. There is no CI check. When you change a token in one, change it in both.
-- `ui_kits/` JSX is not used by the app. Treat it as documentation, not as a future framework migration plan. There is no plan to switch from Svelte to React.
-- Vite (with `sveltekit()` plugin) ignores `.html` files outside `static/` and `.jsx` files outside imports. If anyone adds an `import './design-system/...'` somewhere, the build will start picking up reference material. Do not.
-- The skill is user invocable (`SKILL.md`). External agents may write into `src/design-system/` based on user invocation. Treat the contents as agent-shaped, not human-only.

-
-**Plain English summary.** The complete surface where the Svelte frontend talks to the Rust runtime. Two channels: synchronous request/response via `invoke()`, and asynchronous events via `listen()` / `emit()`. Every command name and every event name the frontend touches is listed here so slice 02 can verify reciprocal mentions.

-
-- **Direction in (Rust → frontend):** events listed under "Tauri events listened to".
-- **Direction out (frontend → Rust):** all `invoke()` commands listed under "Tauri commands invoked".
-- **DOM-only events:** `lumotia:*` `CustomEvent`s on `window`. These never cross the Rust boundary.
-- **Cross-window event:** `lumotia:preferences-changed` is the only one that goes through `emit()`.

-| `lumotia:toggle-recording` | `routes/+layout.svelte` (after hotkey debounce, both backends) | `pages/DictationPage.svelte`. |
-
-## Window APIs
-
-- `getCurrentWindow().minimize()` and `.toggleMaximize()`. `Titlebar.svelte`.
-- `getCurrentWindow().label`. Used to guard hotkey registration to the main window only and to filter own-source preference echoes.
-- `convertFileSrc(absolutePath)`. HistoryPage and viewer use this for `<audio>` elements.
-
-## Plugins
-
-| Plugin | Used by |
-|---|---|
-| `@tauri-apps/plugin-dialog` | `utils/saveMarkdown.ts`, `pages/FilesPage.svelte:handleBrowse`. |
-| `@tauri-apps/plugin-global-shortcut` | `routes/+layout.svelte` (X11 / macOS / Windows hotkey backend). |
-| `@tauri-apps/plugin-autostart` | SettingsPage launch-at-login toggle. |
-| `@tauri-apps/plugin-notification` | Available, used by nudge bus or a related path. Confirm specific call sites. |
-| `@tauri-apps/plugin-opener` | Available, used to open external URLs. Confirm specific call sites. |
-
-## Watch outs
-
-- The truncated grep returned `tts_s...` as a unique prefix. Verify every TTS command name (`tts_speak`, possibly `tts_stop`) against `lib.rs` to make sure the table above is exhaustive.
-- The "preview-*" events have two flavours: `lumotia:` namespaced (`preferences-changed`) and bare (`preview-listening`, `preview-cleanup`, `preview-hide`, `preview-append`, `preview-final`). The bare names are scoped to the overlay window's two-way handshake. Do not rename.
-- `lumotia:open-wind-down` listener is in `+layout.svelte` so the page opens regardless of which window the tray click came from. If you ever isolate windows further, this assumption breaks.
-- `task-window-focus` is the only event sent specifically to the float window.
-- DOM `CustomEvent` handlers do not survive across windows (they are window-local). The tasks list refresh trick on focus relies on this.

-
-Public exports:
-- `initI18n()`. Idempotent. Called from every layout's `onMount`-ish path (`+layout.svelte:38` and the float/viewer/preview break layouts).
-- `setLocale(code)`. Writes to `lumotia_locale` and updates the svelte-i18n store.
-- `currentLocale`. A derived store that components subscribe to via `$currentLocale`.
-- `SUPPORTED_LOCALES` constant for the picker.
-
-### Locale JSON shape
-
-19 lines per file means roughly a dozen translated strings. Treat the locales as a stub. Most page text is still hardcoded.
-
-## Where it is consumed
-
-- `SettingsPage.svelte:22` imports `_` (the translation function) and `SUPPORTED_LOCALES`, `setLocale`, `currentLocale`. The locale picker UI lives in Settings.
-- A handful of strings inside SettingsPage use `$_('key')`.
-
-## Watch outs
-
-- Adding a new locale is one `register("xx", () => import("./locales/xx.json"))` call plus a `SUPPORTED_LOCALES` entry.
-- Cross window: each window initialises i18n independently via its layout. Locale change persists to `localStorage["lumotia_locale"]`. Float and viewer pick up the new locale on the next mount, not live. Worth wiring a Tauri event if live cross-window translation is needed.
-- The "British English" toggle in `settings.britishEnglish` is a transcription post-processing flag (slice 04 territory), not a UI locale. Not wired through svelte-i18n.
-- Default locale is detected from `navigator.language`. In Tauri, this is the OS locale.

-# Pages overview
-
-> **Where you are:** [Architecture map](../README.md) → [Frontend](README.md) → Pages overview
-
-**Plain English summary.** Lumotia has seven main window pages and three secondary window pages. The main window picks which to show by reading `page.current` (a string in the `page` store) and rendering the matching component. The secondary windows are routed by URL (`/float`, `/viewer`, `/preview`).
-
-## At a glance
-
-- **Main window pages live at** `src/lib/pages/*.svelte` (7 files, 6 232 LOC).
-- **Secondary window pages live at** `src/routes/{float,viewer,preview}/+page.svelte` (3 files, 1 361 LOC).
-- **Switch site:** `src/routes/+page.svelte:18-32`.
-- **Driver store:** `src/lib/stores/page.svelte.ts:24-33` (`page.current`).
-- Possible values of `page.current`: `"first-run" | "dictation" | "files" | "tasks" | "history" | "settings" | "shutdown"`. Plus the legacy `"profiles"` which is rewritten to `"settings"` (see README debt note 5).
-
-## Map of pages
-
-### Main window
-
-| Page | File | LOC | One line hook |
-|---|---|---|---|
-| Dictation | `src/lib/pages/DictationPage.svelte` | 1 100 | The hero recording surface. Streams partial transcripts via a Tauri `Channel`, runs the AI cleanup pipeline, paste/copy/export, extracts tasks, fills a template. |
-| Settings | `src/lib/pages/SettingsPage.svelte` | 2 484 | The configuration panel. Audio devices, vocabulary, profiles, templates, model management (Whisper + Parakeet + LLM), hotkey, rituals, nudges, accessibility, diagnostics. |
-| History | `src/lib/pages/HistoryPage.svelte` | 974 | Browse, search, play, edit, star, tag, export saved transcripts. Backed by SQLite FTS5. |
-| Tasks | `src/lib/pages/TasksPage.svelte` | 725 | Inbox/today/soon/later board with energy chips, lists, completion sparkline. |
-| Files | `src/lib/pages/FilesPage.svelte` | 263 | Drop or browse audio/video files. Calls `transcribe_file`. |
-| First run | `src/lib/pages/FirstRunPage.svelte` | 337 | Hardware probe (`probe_system`), model recommendation, model download. Auto exits to dictation. |
-| Shutdown ritual | `src/lib/pages/ShutdownRitualPage.svelte` | 169 | Evening wind down ritual. Triggered from the tray menu via `lumotia:open-wind-down`. |
-
-### Secondary windows (URL routed)
-
-| Window label | URL | File | LOC | One line hook |
-|---|---|---|---|---|
-| `tasks-float` | `/float` | `src/routes/float/+page.svelte` | 481 | Detached pinned tasks window with quick add and list management. |
-| `transcript-viewer` | `/viewer` | `src/routes/viewer/+page.svelte` | 606 | Transcript editor with synced audio playback and per segment editing. |
-| `transcription-preview` | `/preview` | `src/routes/preview/+page.svelte` | 274 | Borderless overlay showing live transcription with copy and revert. |
-
-## How navigation actually happens
-
-- Sidebar buttons set `page.current` directly (`src/lib/Sidebar.svelte:24`).
-- Some flows reach into `page.current` from outside the sidebar:
-  - Hotkey press forces dictation: `+layout.svelte:139, 181`.
-  - First run gate on mount: `+layout.svelte:350`.
-  - Settings page "open evening wind down" button: `SettingsPage.svelte:816`.
-  - Tray menu wind down event: `+layout.svelte:251-254`.
-  - First run completion paths back to dictation: `FirstRunPage.svelte:83, 139, 146, 155`.
-  - Implementation intentions store can route to tasks (`implementationIntentions.svelte.ts:125, 136, 142`).
-  - Shutdown ritual exit: `ShutdownRitualPage.svelte:67`.
-  - TaskSidebar "open tasks page" link: `TaskSidebar.svelte:48`.

-The shell renders sidebar plus a single main slot: `<div class="flex-1 overflow-hidden bg-bg">{@render children()}</div>`. The optional task sidebar (`page.taskSidebarOpen`) can dock a `TaskSidebar` panel beside any main page that is not first run.

-
-## What's in here
-
-### Local state (selected)
-
-- `transcript` (string), `segments` (array of `{start, end, text}`).
-- `recording` is on the global `page` store; this page mirrors it.
-- `timerInterval`, `startTime`, `timerText` (mm:ss).
-- Model lifecycle flags: `modelReady`, `modelLoading`, `needsDownload`.
-- AI flags: `aiProcessing`, `aiStatus`, `extractedCount`.
-- Live session: `sessionId`, `drainingSessionId`, `lastResultAt`, `lastLiveActivityAt`, `liveWarning`.
-- Tauri channels (typed): `resultChannel`, `statusChannel` opened by `new Channel(...)`.
-- UI: `showExportMenu`, `saved`, `insertPos` (cursor-based insertion), `activeTemplate`.
-- `runtimeCapabilities` (from `get_runtime_capabilities`, used to decide engine availability and CUDA presence).
-
-### Lifecycle
-
-- `onMount`. Loads `runtimeCapabilities` (`DictationPage.svelte:134`). Sets up the global hotkey custom event listener (`lumotia:toggle-recording`, dispatched from the `+layout.svelte` hotkey path).
-- `onDestroy`. Tears down listeners and timers.
-
-### Recording flow (high level)
-
-1. Toggle from the mic button or the `lumotia:toggle-recording` window event.
-2. If model not ready, ensure model: check `check_engine`, `check_parakeet_engine`, `check_llm_model`, then load via `load_model` / `load_parakeet_model` / `load_llm_model` as required (`DictationPage.svelte:241-272`).
-3. Open two `Channel<message>` instances (`DictationPage.svelte:341-342`) and call `start_live_transcription_session` with the channel handles.
-4. As the backend pushes status and partial result messages, append text to `transcript`, update `segments`, and broadcast `preview-append` to the preview overlay window (`DictationPage.svelte:165, 381, 385`). If the preview is enabled and not already open, `open_preview_window` is invoked.
-5. On stop, call `stop_live_transcription_session`, then run AI cleanup (`cleanup_transcript_text_cmd`) gated on `get_llm_status` (`DictationPage.svelte:464-472`).
-6. Optionally extract tasks via `extract_tasks_from_transcript_cmd` (`DictationPage.svelte:487-491`) and add them via the `addTask` store helper.
-7. Push to history with `addToHistory` (which calls `add_transcript`).
-8. Auto copy and/or auto paste based on `settings.autoCopy` / `settings.autoPaste`. Paste path uses `paste_text` (`DictationPage.svelte:544-554`); fallback to `copy_to_clipboard`.
-9. Emit `preview-cleanup`, `preview-final`, `preview-hide` to drive the overlay state machine (`DictationPage.svelte:531, 539, 606`).

-Plus `emit("preview-append" | "preview-listening" | "preview-cleanup" | "preview-final" | "preview-hide")`.
-
-## Watch outs
-
-- The page uses `// @ts-nocheck`. Adding type safety here would catch a class of regressions, especially around the `Channel<T>` payload shape.
-- The cursor based insertion (`insertPos`) is fragile. Editing the textarea while a live session is running can corrupt the segment offset map. Tests around `extractTasks` only cover the post stop path.
-- Multiple paths can flip `recording` (button, hotkey custom event, error early-out). Treat the page as a state machine with a single source of truth and you will save yourself.
-- `extractedCount` is purely cosmetic. It is reset on recording start.
-- The "live activity" stalled detector is timer based (`lastLiveActivityAt`). On a stalled session the user sees `liveWarning`. The recovery path is "stop and start again".

-
-## What's in here
-
-### Drag and drop
-
-- `onMount` registers three Tauri events:
-  - `tauri://drag-drop` (`FilesPage.svelte:28`). Filters the dropped paths to supported extensions and starts transcription.
-  - `tauri://drag-enter` (`FilesPage.svelte:34`). Sets `isDragOver = true`.
-  - `tauri://drag-leave` (`FilesPage.svelte:35`). Sets `isDragOver = false`.
-- `onDestroy` calls each unlisten.
-
-### Browse
-
-- `handleBrowse()` lazy imports `@tauri-apps/plugin-dialog` and opens with the audio/video filter (`mp3, wav, m4a, mp4, flac, ogg, webm, mov, mkv`).
-
-### Transcription
-
-- Calls `invoke("transcribe_file", { ... })` (`FilesPage.svelte:76`). Receives transcript text + segments.
-- Optional `copy_to_clipboard` on completion.
-- Pushes result into history via the store helper.
-
-### State

-
-## Tauri command surface
-
-`transcribe_file`, `copy_to_clipboard`. Plus dialog plugin.
-
-## Watch outs
-
-- The drag and drop events require the Tauri config to declare drag drop on the relevant window. If the events do not fire, check `tauri.conf.json` and slice 02.
-- Long files block the UI of this page until `transcribe_file` resolves. There is no abort.
-- The supported extensions list is duplicated between the file dialog filter and (presumably) the Rust side. Drift risk.
-- Multi file drag drop iterates serially. No queue UI.

-
-## What's in here
-
-### Probe
-
-- `onMount` calls `probe_system` and `rank_models` (`FirstRunPage.svelte:31-32`) to compute recommended models given the user's RAM, GPU, OS.
-- Sets `probing = false` and renders the recommendation UI.
-
-### Download
-
-- `downloadAndGo(modelId)` (`FirstRunPage.svelte:55-95`):
-  - Subscribes to `model-download-progress` and `parakeet-download-progress` events.
-  - Calls `download_model` then `load_model` (Whisper) or `download_parakeet_model` then `load_parakeet_model`.
-  - On success, sets `ready = true` and routes to dictation (`page.current = "dictation"`).
-  - Computes `estimatedMinutes` from elapsed and progress percent (`derived.by`).
-
-### Triggering
-
-- The shell auto sets `page.current = "first-run"` if `list_models` and `list_parakeet_models` are both empty (`+layout.svelte:346-353`).

-
-- The download is a single shot. There is no resume on cancel; if the user closes the app mid download, they restart from zero. Slice 02/05 may improve this later.

-
-- Loads via `loadHistory` (which calls `list_transcripts` in Rust).
-- Search input filters client side (FTS happens server side via `search_transcripts` for some flows; check `page.svelte.ts`).
-- Virtualised scrolling using `buildCumulativeOffsets` and `findVisibleRange` from `utils/virtualList.ts`. Row heights use `measurePreWrap` to compute pre wrap heights from the live preferences font.
-- Constants: `COLLAPSED_ROW_MIN_HEIGHT`, `COLLAPSED_ROW_VERTICAL_PADDING`, `EXPANDED_BASE_HEIGHT`, `EXPANDED_PADDING`, etc.
-
-### Audio playback
-
-- `convertFileSrc()` maps the saved audio path to a webview URL.
-- Inline `<audio>` element. Speed control uses `PLAYBACK_SPEEDS` (`[0.5, 1, 1.5, 2, 3, 5]`).

-- Open in viewer window (`open_viewer_window`, then handoff via `localStorage`).
-- Auto tag (calls `extract_content_tags_cmd`, returns suggested tags merged into `tags`).
-- Rename via `renameHistoryEntry` store helper.
-- Export to markdown via `saveTranscriptAsMarkdown`.
-
-### Bulk

-- Bulk auto tag walks the visible list and calls `extract_content_tags_cmd` per row.
-- Bulk export to directory via `exportTranscriptsToDir`.
-
-## Tauri command surface
-
-`delete_transcript`, `copy_to_clipboard`, `open_viewer_window`, `extract_content_tags_cmd`. Plus indirect commands from store helpers (`add_transcript`, `update_transcript`, etc) and the dialog plugin used by `saveMarkdown.ts`.
-
-## Watch outs
-
-- Virtual scrolling assumes stable row heights once measured. Toggling preferences (font size, line height) invalidates the measure. The page recomputes on `getPreferences()` change but watch for stutter on rapid changes.
-- The viewer handoff writes the transcript ID to `localStorage`. The viewer window then loads from SQLite. Do not put transcript text in `localStorage`.
-- Auto tag is rate limited only by user clicks. Bulk over a large library can hammer the LLM. Consider a guard if scaling.
-- `convertFileSrc` paths are valid only inside the Tauri webview. If the audio path is missing or moved, `<audio>` will silently fail; show an error state.

-Built from `SettingsGroup` accordions. Top level groups (line refs are anchors in the file):

-2. **Vocabulary** (`SettingsPage.svelte:1191`). Two nested groups:
-   - **Terms and profiles** (`SettingsPage.svelte:1197`). Vocabulary terms attached to the active profile, plus the active profile selector.
-   - **Profiles and templates** (`SettingsPage.svelte:1415`). Two further nested groups:
-     - **Profiles** (`SettingsPage.svelte:1423`). Create, rename, delete; default profile cannot be deleted.
-     - **Templates** (`SettingsPage.svelte:1481`). Per profile templates injected at recording start.
-3. **Processing** (also referred to in file as the engine + AI tier section). Phase 9c style group with `onopen` hook that probes `check_engine`, `check_parakeet_engine`, `list_models`, `detect_paste_backends`, etc.
-4. **Hotkey**. Wraps `HotkeyRecorder`. Search navigation jumps here when the user clicks the hotkey chip in another section (`SettingsPage.svelte:477`).
-5. **Rituals**. Morning triage, evening wind down toggles.
-6. **Nudges and implementation intentions**. Wraps `ImplementationRulesEditor`.
-7. **Accessibility**. Wraps `AccessibilityControls`. Theme, zone (`ZonePicker`), font family, sizes, line height, letter spacing, bionic reading, reduce motion.
-8. **Read aloud (TTS)** (`SettingsPage.svelte:759`). Voice selection from `tts_list_voices`, rate, sample play.
-9. **Diagnostics** (`SettingsPage.svelte:377-405`). Generates and saves a redacted diagnostic report.
-10. **Tasks** (sparkline toggle, relocated in Phase 9c).
-11. **Launch at login**. Wires `@tauri-apps/plugin-autostart`.

-## Watch outs
-
-- 2 484 lines, hand rolled accordion, Phase 9c handover already deferred the deeper restructure. New options should be added inside the existing `SettingsGroup` topology rather than threaded into the global header.
-- `settings.theme` ("Light"/"Dark"/"System") is the legacy field; `preferences.theme` is the new one. `+layout.svelte:61-68` re maps every effect cycle. Adding new theme options needs both stores.
-- `page.current = "shutdown"` button at line 816 is the only entrance from settings into the wind down ritual (other than the tray).
-- The `model-download-progress` event payload is shared across Whisper and Parakeet listeners. Take care that progress UI does not cross wires when both downloads run concurrently (rare but possible if `+layout.svelte` triggers a prewarm while Settings is open).
-- The diagnostics path strips secrets in Rust; do not re add raw paths or env values to the report payload here.
-- Accessibility writes go through `preferences` (Tauri persisted) but `settings.fontSize` writes through `localStorage`. Two persistence channels for similar surfaces.

-> **Where you are:** [Architecture map](../README.md) → [Frontend](README.md) → Stores
-
-**Plain English summary.** Reactive state. Lumotia uses Svelte 5 runes (`$state`, `$derived`, `$effect`) instead of legacy stores. Each file under `src/lib/stores/` exports one (or more) `$state` objects plus the helper functions that read or mutate them. Components import the state directly and Svelte tracks reactivity automatically. Two persistence channels: `localStorage` for settings, profiles, task lists, templates; Tauri (`save_preferences`) for accessibility preferences.
-
-## At a glance
-
-- **Path:** `src/lib/stores/`
-- **Files:** 10 (4 085 LOC across stores + utils + types).
-- **Cross window sync:**
-  - `localStorage` `storage` event in the float window for settings.
-  - Tauri `emit("lumotia:preferences-changed")` for preferences (handled by every layout).
-- **Persistence keys:** `lumotia_settings`, `lumotia_profiles`, `lumotia_task_lists`, `lumotia_templates`, `lumotia_locale`, plus a viewer handoff key.
-
-## The stores
-
-### `page.svelte.ts` (697 LOC). The big one.
-
-Owns:
-- `page` (`PageState`): `current`, `status`, `statusColor`, `activeProfile`, `recording`, `timerText`, `handedness`, `taskSidebarOpen`. Initial: `current = "dictation"`.
-- `settings` (`SettingsState`). Persisted to `localStorage["lumotia_settings"]` via `utils/settingsMigrations.ts`. Defaults at line 60 onward. Includes engine choice, model size, language, device, format mode, fillers, anti hallucination, British English, auto copy/paste, transcription preview, meeting auto capture (+ apps list), sound cues + volume, timestamps, theme, font size, AI tier, LLM model id and prompt preset, GPU concurrency, prewarm flag, save audio, output folder, global hotkey, sidebar collapsed, microphone device, energy state, match my energy, TTS voice + rate, rituals (morning/evening + time), launch at login, ritualsPromptSeen, nudges (enabled/muted/speakAloud), showMomentumSparkline.
-- `profiles`, `templates`, `taskLists` arrays.
-- `tasks` and `history` arrays.
-
-Helpers (selected, with line refs):
-- `addToHistory` → `add_transcript` (`page.svelte.ts:234`).
-- `mapTranscriptRow`, `saveTranscriptMeta` → `update_transcript` (`page.svelte.ts:272`).
-- `deleteFromHistoryById` → `delete_transcript` (`page.svelte.ts:320`).
-- `addTask`, `completeTask`, `uncompleteTask`, `deleteTask`, `setTaskEnergy`, `updateTask` → matching `*_task_cmd` Rust commands. `completeTask` and friends emit `lumotia:task-completed | -uncompleted | -deleted` window events (line 470 onward).
-- Task lists: `addTaskList`, `renameTaskList`, `deleteTaskList`, `moveTaskList`, `sortTaskLists`, `moveTaskToList`, `moveTaskListToProfile`.
-- Profile mutators: `addProfileTaskList`, `removeProfileTaskList`.
-- `saveSettings`, `saveProfiles`, `saveTemplates` write to `localStorage`.
-
-### `preferences.svelte.ts` (172 LOC).
-
-Owns the `Preferences` shape: `theme` ("light" | "dark" | "system"), `zone` ("default" | ...), `accessibility` (`fontFamily`, `fontSize`, `letterSpacing`, `lineHeight`, `transcriptSize`, `bionicReading`, `reduceMotion`).
-
-- DOM is the source of truth at runtime: `readFromDOM()` reads `<html>` data attributes and CSS variables; `applyToDOM(prefs)` writes them.
-- Persists via `invoke("save_preferences", { preferences: JSON.stringify(prefs) })` with a debounce. Failure shows a single toast per process (`preferences.svelte.ts:101-120`).
-- Cross window: `broadcastPreferences` calls `emit("lumotia:preferences-changed", { source, prefs })`. Receivers in `+layout.svelte` and the secondary `+layout@.svelte` files apply external prefs after a label check.
-- Exposes `getPreferences`, `updatePreferences`, `updateAccessibility`, `applyExternalPreferences`, `PREFERENCES_CHANGED_EVENT` constant.
-- Font families resolved from a constant map (Lexend, Atkinson, OpenDyslexic).
-
-### `profiles.svelte.ts` (123 LOC).
-
-The vocabulary profile store (separate from the `profiles` array on `page.svelte.ts`). Holds:
-- `activeProfileId`, list of profiles, vocabulary terms.
-
-Tauri commands: `load_profiles_cmd` (implicit on load), `update_profile_cmd`, `delete_profile_cmd`, `delete_profile_term_cmd`, plus add term commands.
-Exposes `DEFAULT_PROFILE_ID`.
-
-### `toasts.svelte.ts` (99 LOC).
-
-Toast notifications. State is an array of `{id, severity, title, body, duration}`.
-
-Helpers: `toasts.info(title, body?)`, `.warn`, `.error`, `.success`, plus `dismiss(id)`. Auto dismiss via `setTimeout`. Read by `ToastViewport.svelte`.
-
-### `llmStatus.svelte.ts` (64 LOC).
-
-Tracks the LLM lifecycle pill. State is one of `idle | loading | generating | downloading | unavailable`.
-
-- `refreshLlmStatus(aiTier)` calls `get_llm_status` and updates the chip.
-- `markGenerating()`, `markGenerationDone()` are called around `cleanup_transcript_text_cmd` in `DictationPage.svelte`.
-
-### `completionStats.svelte.ts` (59 LOC).
-
-Phase 8 gamification. Owns `recentCompletions` (`DailyCompletionCount[]`) and a `todayCount` derivation.
-
-Refresh triggers (no polling): module load, `lumotia:task-completed`, `lumotia:step-completed`, `lumotia:task-uncompleted`, `lumotia:task-deleted`, window focus (for midnight rollover).
-
-### `focusTimer.svelte.ts` (238 LOC).
-
-Owns the floating focus timer. State: target ms, started at, label, taskId, paused.
-
-- `setInterval` at 250 ms (`TICK_INTERVAL_MS`).
-- Triggered by `lumotia:start-timer` window events. Emits `lumotia:focus-timer-cancelled` and `lumotia:focus-timer-complete` on transitions.
-
-### `implementationIntentions.svelte.ts` (260 LOC).
-
-"When X happens, do Y" rules engine. Owns the rules array.
-
-- 30 second `setInterval` (`TIME_RULE_POLL_MS`) checks time based rules.
-- On match, can route `page.current = "tasks"` (lines 125, 136, 142) and call `tts_speak` if speak aloud is enabled (line 170).
-- Uses `delete_implementation_rule` to remove a rule (line 82).
-- Emits `lumotia:implementation-rules-changed` after writes.
-- Lifecycle: `startImplementationIntentions`, `stopImplementationIntentions` from `+layout.svelte`.
-
-### `nudgeBus.svelte.ts` (292 LOC).
-
-Owns the nudge engine. Two `setInterval` handles:
-- `blurCheckHandle` for window blur detection.
-- `triagePollHandle` at 5 minute cadence checking morning triage triggers.
-- Plus a `microStepTimers` Map for per task delayed notifications.
-
-Key commands: `deliver_nudge` (line 112), `tts_speak` (line 119).
-Emits `lumotia:morning-triage-finished` after the modal closes.
-Lifecycle: `startNudgeBus`, `stopNudgeBus` from `+layout.svelte`.
-
-### `speaker.svelte.ts` (10 LOC).
-
-Tiny. Holds `speakingId` so `SpeakerButton` instances can debounce / cancel each other. Candidate for collapsing into a util (README debt note 9).
-
-## Cross store traffic
-
-- `DictationPage.completeRecording()` → `addToHistory` (page) → `add_transcript` Rust → push to history.
-- `MicroSteps` "start timer" button → `lumotia:start-timer` → `focusTimer` store transitions → `FocusTimer` component renders ring.
-- `TasksPage.addTask` → `tasks` store → emits `lumotia:task-completed/...` → `completionStats` refreshes → `CompletionSparkline` re renders.
-- `SettingsPage` accessibility toggle → `updatePreferences` → DOM write + `save_preferences` invoke + `lumotia:preferences-changed` emit → secondary windows mirror.
-- Float window settings sync uses `localStorage` `storage` event, not the Tauri preference event. Drift candidate.
-
-## Watch outs
-
-- `page.svelte.ts` is doing a lot. Splitting transcripts, tasks, task lists, settings, profiles into separate stores would help but is outside this map's job.
-- `settings` and `preferences` overlap (theme, font size, `transcriptSize`). Settings are localStorage only; preferences are Tauri persisted. Race possible during the migration `$effect`.
-- `nudgeBus` and `implementationIntentions` both run timers. They are torn down in `+layout.svelte` `onDestroy`. Only the main window starts them.
-- `completionStats` listens on the DOM `window` for events; it does not subscribe to `tasks` directly. Adding a new task mutation that does not emit one of the `lumotia:task-*` events will silently break the sparkline.

-# Windows and routes
-
-> **Where you are:** [Architecture map](../README.md) → [Frontend](README.md) → Windows and routes
-
-**Plain English summary.** Lumotia is a single SvelteKit build that runs as multiple desktop windows. The Rust side opens four webviews (main, tasks float, transcript viewer, transcription preview) and points each one at a different SvelteKit route. The frontend uses SvelteKit's `+layout@.svelte` "break" trick so secondary windows skip the main shell (sidebar, titlebar, toast viewport) and render a focused, single purpose UI.
-
-## At a glance
-
-- **Path:** `src/routes/`
-- **LOC:** 2 740 across the route tree.
-- **Key files:**
-  - `src/routes/+layout.js:5`. Disables SSR. Adapter is `adapter-static` with `index.html` fallback (`svelte.config.js:6`). The whole tree is SPA only.
-  - `src/routes/+layout.svelte`. The shell. Sidebar, custom titlebar (non Linux only), toast viewport, focus timer overlay, morning triage modal, resize handles, global hotkey wiring, OS detection, profile load, first run gate, error capture.
-  - `src/routes/+page.svelte`. The main window's page switch (`page.current` → 7 page modules).
-  - `src/routes/float/+layout@.svelte`. "Break" layout for the tasks float window.
-  - `src/routes/float/+page.svelte`. Tasks float window UI.
-  - `src/routes/viewer/+layout@.svelte`. Break layout for the transcript editor window.
-  - `src/routes/viewer/+page.svelte`. Transcript editor with audio playback.
-  - `src/routes/preview/+layout@.svelte`. Break layout for the live transcription preview overlay.
-  - `src/routes/preview/+page.svelte`. Preview state machine: listening → live → cleanup → final.
-- **Imports:**
-  - Internal: every store, plus shell components (`Sidebar`, `TaskSidebar`, `Titlebar`, `ToastViewport`, `ResizeHandles`, `FocusTimer`, `MorningTriageModal`).
-  - External: `@tauri-apps/api/core` (invoke, Channel, convertFileSrc), `@tauri-apps/api/event` (listen, emit), `@tauri-apps/api/window` (getCurrentWindow), `@tauri-apps/plugin-global-shortcut`, `@tauri-apps/plugin-dialog`, `lucide-svelte`.
-- **Used by:** Tauri (slice 02). Window labels are `main`, `tasks-float`, `transcript-viewer`, `transcription-preview`. Each is created with the matching route URL.
-
-## What's in here
-
-### `src/routes/+layout.js` (5 LOC)
-
-Single line: `export const ssr = false;`. Tauri has no Node server, so SvelteKit must run as a SPA.
-
-### `src/routes/+layout.svelte` (493 LOC)
-
-The shell. Mounts on every window (the secondary windows then render only `{@render children()}` and suppress the chrome).
-
-Responsibilities:
-- Initialise svelte-i18n (`initI18n()` is idempotent across windows, `+layout.svelte:38`).
-- Detect Tauri runtime (`hasTauriRuntime`) and OS (`loadOsInfo`). Linux uses native KWin/Mutter decorations; macOS and Windows render the custom `Titlebar` plus invisible `ResizeHandles`. Default `useCustomChrome = false` to avoid a flash on Linux (`+layout.svelte:49`).
-- Hotkey backend selection. On Wayland, attempt the evdev backend (`check_hotkey_access`). Otherwise fall back to `tauri-plugin-global-shortcut`. Falls back to "unavailable" if neither path works (`+layout.svelte:76-102`).
-- Hotkey registration. Only the `main` window owns the global shortcut. The function debounces evdev autorepeat at 120 ms (Handy issue #1143 referenced in comments, `+layout.svelte:171-186`).
-- Cross window listeners: `lumotia:hotkey-pressed` (evdev path), `lumotia:open-wind-down` (tray menu), `lumotia:preferences-changed` (sync prefs across windows). Apply external preferences if the source label differs from our own.
-- Theme migration `$effect`. Reads `settings.theme` (legacy "Light" / "Dark" / "System") and writes `preferences.theme` ("light" / "dark" / "system"). See README debt note 2.
-- Font size CSS variable `--font-size-transcript` set on `<body>` from `settings.fontSize`.
-- Global error capture. `window.onerror` and `unhandledrejection` forward to `log_frontend_error` Rust command. Best effort, swallow throws.
-- First run check on mount. If `list_models` and `list_parakeet_models` both return empty arrays, switch `page.current` to `"first-run"`.
-- Background update check via `check_for_update`. Toast on result.
-- Pre warm default model on mount if `settings.prewarmModelOnStartup` (calls `prewarm_default_model_cmd`).
-- Meeting auto capture poller (`$effect`). When `settings.meetingAutoCapture` is true, polls `detect_meeting_processes` every 15 s with the configured patterns (default `["zoom", "teams"]`). Edge triggered (toast only on first match per session). Tear down on effect re run.
-- Sidebar collapse heuristic. `[` toggles, narrow viewport collapses automatically.
-- Render branches: `isSecondaryWindow` (URL starts with `/float` or `/viewer`) renders only children. Otherwise: optional Titlebar, sidebar (hidden on first run), main slot, optional task sidebar (when `page.taskSidebarOpen`).
-- Always rendered alongside: `<ToastViewport />`, `<FocusTimer />`, `<MorningTriageModal />`, `<ResizeHandles />` (custom chrome only).
-
-### `src/routes/+page.svelte` (33 LOC)
-
-Pure dispatcher. Switches the seven page modules from `page.current`:
-- `first-run` → `FirstRunPage`
-- `dictation` → `DictationPage`
-- `files` → `FilesPage`
-- `tasks` → `TasksPage`
-- `history` → `HistoryPage`
-- `settings` → `SettingsPage`
-- `shutdown` → `ShutdownRitualPage`
-
-Also redirects the legacy `page.current === "profiles"` to `"settings"` via `$effect` (debt note 5).
-
-### `src/routes/float/+layout@.svelte` (99 LOC)
-
-The `@.svelte` suffix tells SvelteKit to skip parent layouts. Reimports `app.css`, mounts `Titlebar` (non Linux) and `FocusTimer`, applies the same theme migration `$effect`, listens on the browser `storage` event (not Tauri events) to sync `settings` from main window writes, and handles the `task-window-focus` Tauri event to glow and auto focus the quick add input.
-
-### `src/routes/float/+page.svelte` (481 LOC)
-
-Tasks float window. Self contained quick add, list filter, sort menu, completed toggle, list management (rename, delete, reorder, move to profile), drag and drop reordering. Reads tasks straight from the `page.svelte.ts` store helpers. No `invoke()` calls of its own; mutations go via `addTask`, `completeTask`, etc, which then call Rust.
-
-### `src/routes/viewer/+layout@.svelte` (77 LOC)
-
-Same break layout pattern. Mounts `Titlebar`, `ToastViewport`, applies preferences sync via `lumotia:preferences-changed`, applies theme.
-
-### `src/routes/viewer/+page.svelte` (606 LOC)
-
-Transcript editor. Hydrates from a transcript ID handed off via `localStorage` (`lumotia:viewer-handoff` style key, see file). Fetches the full row from SQLite via `get_transcript`. Renders an `<audio>` element using `convertFileSrc()` to map the saved audio path to a webview URL. Provides per segment editing, debounced autosave through `saveTranscriptMeta`, virtual scrolling via `VirtualSegmentList`, playback speed control (`PLAYBACK_SPEEDS`), starring and tagging.
-
-### `src/routes/preview/+layout@.svelte` (68 LOC)
-
-Mounts only what the overlay needs: theme, preferences sync. No sidebar, no titlebar, no toast viewport.
-
-### `src/routes/preview/+page.svelte` (274 LOC)
-
-Live transcription overlay. Listens for `preview-listening`, `preview-cleanup`, `preview-hide` (and reads partial text via the same `Channel` pattern as Dictation, in some flows). State machine: `listening → live → cleanup → final → auto hide`. Provides a copy button (uses `navigator.clipboard.writeText` first, falls back to `copy_to_clipboard` invoke) and a revert to raw button. Auto hide timer constants live at the top of the file.
-
-## Data flow
-
-- Window creation: Rust opens four webviews and routes them to `/`, `/float`, `/viewer`, `/preview`. The same JS bundle loads in each.
-- Cross window state:
-  - `localStorage` carries `lumotia_settings` and the viewer handoff payload. Float window listens on the browser `storage` event to mirror settings.
-  - Tauri events carry preferences (`lumotia:preferences-changed`), tray driven navigation (`lumotia:open-wind-down`), and float window focus (`task-window-focus`).
-- Hotkey: only the main window registers, but every window's layout includes the migration `$effect`. The label guard at `+layout.svelte:115-121` prevents secondary windows from re registering.
-- First run gating: only the main window evaluates and sets `page.current = "first-run"`. The float/viewer/preview windows skip the shell altogether.
-
-## Watch outs
-
-- The `useCustomChrome` flash is mitigated by defaulting to `false` on Linux. If you ever flip the default, expect a one frame flash of custom chrome before `loadOsInfo()` resolves.
-- The break layouts duplicate the theme migration `$effect`. Touch one, touch all. Same for `applyExternalPreferences` listeners.
-- `transcription-preview` is a borderless overlay with `WindowTypeHint = Utility`. Layout assumptions about chrome height do not apply.
-- `+layout.svelte` calls `applyExternalPreferences` only after a payload `source` check. If you ever add a fifth window, its label must be propagated correctly or the window will echo its own preference writes.
-- Drag drop on `FilesPage.svelte` listens on `tauri://drag-drop` events, which require the window to declare drag drop in `tauri.conf.json`. Slice 02 owns that surface.

-
-> **Where you are:** [Architecture map](../README.md) → Tauri runtime
-
-**Plain English summary.** The Tauri runtime is the bridge between Lumotia's Svelte frontend and the Rust workspace crates. It owns app startup (database init, panic hook, plugin wiring, preferences injection), the system tray, the secondary windows (task float, transcript viewer, transcription preview), and the entire `#[tauri::command]` surface that the frontend invokes for audio capture, transcription, LLM cleanup, task and transcript CRUD, paste, TTS, hotkeys, diagnostics, and more. Everything that runs on the host process but is not pure crate logic lives here.

-## How this slice connects to others
-
-- **Frontend (slice 01).** Every `#[tauri::command]` is invoked from Svelte via `@tauri-apps/api/core` `invoke()`. Events emitted via `app.emit(...)` are consumed via `listen()` in the frontend. Live transcription uses typed `tauri::ipc::Channel` instead of plain events; the channel pair is created on the JS side and passed in as command args.
-- **Audio + transcription (slice 03).** `commands::audio` calls `lumotia_audio::{MicrophoneCapture, WavWriter, decode_audio_file_limited, resample_to_16khz, probe_audio_duration_secs}`. `commands::transcription` and `commands::live` call `lumotia_transcription::LocalEngine` plus `lumotia_audio::StreamingResampler`. `commands::models` calls `lumotia_transcription::{model_manager, load_whisper, load_parakeet}`.
-- **LLM + formatting + MCP (slice 04).** `commands::llm` calls `lumotia_llm::{LlmEngine, model_manager, ContentTags, LlmModelId}` and `lumotia_ai_formatting::{llm_cleanup_text, LlmPromptPreset}`. `commands::tasks` calls `lumotia_llm::prompts::FeedbackExample` and the engine's `decompose_task_with_feedback` / `extract_tasks_with_feedback` / `extract_content_tags`. `commands::transcription` and `commands::live` call `lumotia_ai_formatting::{post_process_segments, FormatMode, PostProcessOptions}`. `commands::profiles` calls `lumotia_ai_formatting::extract_corrections` for auto-learned vocabulary.
-- **Core + storage + hotkey + build (slice 05).** Everything DB-touching goes through `lumotia_storage` (`init`, `database_path`, `get_setting`, `set_setting`, `prune_error_log`, the full set of CRUD helpers, `app_data_dir`, `crashes_dir`, `logs_dir`, `list_recent_errors`, `log_error`). `commands::hardware` and `commands::models` call `lumotia_core::{hardware, model_registry, recommendation, types, constants}`. `commands::meeting` calls `lumotia_core::process_watch`. `commands::hotkey` is a thin Tauri wrapper around `lumotia_hotkey::{EvdevHotkeyListener, HotkeyCombo, HotkeyEvent}`. `build.rs` is the build-system half of the slice (CSP regression guard plus ggml multi-definition link arg).
-
-## Open questions / debt
-
-- `commands/live.rs` is 1,737 LOC. The runtime, loop state, speech gate, dedup, and chunking logic share the file. Splitting per concern would track against the broader refactor pass already mooted in the in-repo code review (`docs/code-review-2026-04-22.md`). See [`commands/live.md`](commands/live.md) for the breakdown.
-- `commands::update::install_update` returns a hard-coded "Updates are disabled until release signing is configured." (`src-tauri/src/commands/update.rs:15`). The integration test `updater_is_signed_or_absent` (`src-tauri/tests/config_hardening.rs:35`) only asserts that *if* an updater config ships, it carries a non-empty pubkey. There is currently no updater config in `tauri.conf.json`, so the test is an empty no-op.
-- `commands::power::PowerAssertion` is a no-op on Linux and Windows (`src-tauri/src/commands/power.rs:90`). Only macOS has a real implementation via `objc2`. The doc comment promises `SetThreadExecutionState` (Windows) and logind inhibitors (Linux), but neither is wired up. Symptom: long live-dictation sessions on Linux can be idled by the compositor.
-- `src-tauri/.cargo/config.toml` hard-codes `LIBCLANG_PATH = "C:\\Program Files\\LLVM\\bin"` (Windows). It is harmless on non-Windows hosts (env var is just unused) but it is a foot-gun if someone moves Clang elsewhere on Windows. See [Cargo and features](cargo-and-features.md).
-- The Linux rendering workaround in `lib.rs` (`warn_if_x11_env_unset_on_wayland`) now warns when the launcher has not set the expected env vars; it no longer mutates the process environment. In development, `run.sh` / `npm run dev:tauri` owns the defaults (`WEBKIT_DISABLE_DMABUF_RENDERER=1` on Linux; `GDK_BACKEND=x11` and `WINIT_UNIX_BACKEND=x11` on Wayland). The user opt-out remains `WEBKIT_DISABLE_DMABUF_RENDERER=0`, set before launching.
-- `commands::diagnostics::install_panic_hook` writes a "minimal text dump" without backtraces unless the user has `RUST_BACKTRACE=1` set (`src-tauri/src/commands/diagnostics.rs:42`). The packaged binary does not set it, so production crash dumps will lack stack traces. Document or default-enable.
-- `commands::audio::list_audio_devices` is gated `ensure_main_window` but the `secondary-windows` capability does not invoke it, which is correct. The `clipboard::copy_to_clipboard` command, by contrast, has no main-window guard and any window with the `core:default` permission can call it; intentional, but worth flagging.

-- `docs/code-review-2026-04-22.md`. The MAJOR / MINOR review that motivated several of the safety helpers seen here (the parallel-mode loopback CSP guard in `build.rs`, secondary-window high-risk-permission test, RB-06 worker-join in `commands::audio`, RB-07 `compose_accelerators` in `commands::models`, RB-08 macOS App Nap power assertion in `commands::power`).
-- `docs/issues/`. Open issue threads, several of which the diagnostic-report bundler exists to feed.
-- `docs/whisper-ecosystem/brief.md`. Source of the numbered "brief items" cited in code comments (item #2 = loopback LLM CSP, item #9 = App Nap, items #10/#17 = paste / replace flows, item #19 = progressive WAV writer, item #28 = sequential-GPU mode).
-- `docs/handovers/`. Daily handover docs that cite specific command surfaces; useful when the in-source comments cite a "RB-NN review point".
-- `docs/dev-setup.md`. Linux + Windows + macOS toolchain setup, including the Vulkan loader install required for GPU-backed whisper.cpp.
