docs: architecture map (initial 5-slice generation, 105 pages)

Five-slice navigable map of the entire codebase under
docs/architecture-map/. Each slice is a self-contained
breadcrumbed sub-tree:

  01-frontend (16)              Svelte/SvelteKit UI
  02-tauri-runtime (26)         src-tauri commands + lifecycle
  03-audio-transcription (16)   audio + transcription crates
  04-llm-formatting-mcp (19)    llm, ai-formatting, mcp, cloud
  05-core-storage-hotkey-build  core, storage, hotkey, workspace,
                          (26) CI, dev glue

Plus master README.md and data-flow-end-to-end.md tracing
audio bytes from microphone to FTS5 search to MCP read.

Generated by 5 parallel subagents on 2026/05/09 against
HEAD 3c47000. Each page has YAML frontmatter, file:line code
refs, sibling cross-links, plain-English summaries.

Aggregated debt surfaced (full lists in master README):
RB-08 macOS power assertion, schema head drift v14 vs v15,
VAD blocked on ort version conflict, streaming primitives
not wired into live.rs, no prompt versioning, MCP has no
auth, cloud-providers in-memory keystore, SettingsPage
2 484 LOC, commands/live.rs 1 737 LOC, dual theme system,
brand rename to Lumenote pending across the codebase.

+# Tasks page
+
+> **Where you are:** [Architecture map](../../README.md) → [Frontend](../README.md) → [Pages overview](../pages-overview.md) → Tasks
+
+**Plain English summary.** The full screen tasks board. Inbox, today, soon, later buckets. Per task energy chips (low/medium/high), per task lists, micro steps, completion sparkline, search, sort, drag to reorder, and a "pop out" button that opens the same tasks in a small persistent floating window via `open_task_window`.
+
+## At a glance
+
+- **Path:** `src/lib/pages/TasksPage.svelte`
+- **LOC:** 725
+- **Imports (selected):**
+  - Stores: from `page.svelte.ts`: `tasks`, `addTask`, `completeTask`, `uncompleteTask`, `deleteTask`, `updateTask`, `setTaskEnergy`, `taskLists`, `addTaskList`, `renameTaskList`, `deleteTaskList`, `settings`, `saveSettings`. From `completionStats.svelte.ts`: `recentCompletions`, `todayCount`.
+  - Components: `WipTaskList`, `EmptyState`, `CompletionSparkline`, `EnergyChip`, `Card`.
+  - Utils: `formatTimestamp` (time). `BUCKET_COLORS`, `EFFORT_LABELS`, `EFFORT_ORDER` (constants).
+  - External: `lucide-svelte` (`SquareCheck`, `Search`, `ExternalLink`, `ChevronLeft`, `ArrowUpDown`, `Plus`, `X`, `ChevronRight`, `Zap`).
+
+## What's in here
+
+### Local state
+
+- `activeBucket` (`"all" | "inbox" | "today" | "soon" | "later"`).
+- `activeListId` (`"all" | "inbox" | <listId>`).
+- `showCompleted`, `quickInput`, `searchQuery`, `sidebarCollapsed`.
+
+### Render
+
+- Quick add input (top). Sets bucket via segmented choice, energy via `EnergyChip`.
+- Filter / sort header. Sort modes use `EFFORT_ORDER` for effort comparisons.
+- Task list body uses `WipTaskList` (which renders rows with `MicroSteps` expansion).
+- "Pop out" icon → `invoke("open_task_window")` (`TasksPage.svelte:231`).
+- Sparkline panel renders `CompletionSparkline` if `settings.showMomentumSparkline` is true.
+
+### Stores it depends on
+
+- `tasks` (live array). `taskLists`. `recentCompletions` for the sparkline.
+
+### Events
+
+- Listens implicitly to: `magnotia:task-completed`, `magnotia:task-uncompleted`, `magnotia:task-deleted`, `magnotia:step-completed` are emitted from store helpers and consumed by `completionStats.svelte.ts` to refresh the sparkline.
+
+## Tauri command surface (direct)
+
+- `open_task_window` (page action).
+
+The store helpers used here call into Rust through `add_task_cmd`, `complete_task_cmd`, `uncomplete_task_cmd`, `delete_task_cmd`, plus list management commands (`*_task_list_cmd`).
+
+## Watch outs
+
+- Drag and drop is heavy on this page. Reorder mutations should always go via the store helpers; do not manipulate `tasks` directly or you will desync the SQLite source of truth.
+- The sparkline is gated on `settings.showMomentumSparkline` (true by default). It re renders on the four `magnotia:task-*` events, plus window focus for date rollover.
+- "Pop out" deliberately does not pass any state. The float window reads the same store, which is shared via store hydration on mount and `localStorage` for `settings`.
+- Sort, filter, search are not persisted. Reload returns to defaults.
+
