Inventory of workspace shape, LOC, dependency graph, public API surface, external surfaces (Tauri commands / MCP tools / frontend routes), and a README↔code drift log. Input for Phase 1 (lean-pass). Surfaces five concrete README drifts (one HIGH: stores list fiction; two MED: undocumented Tauri modules and a Moonshine claim with no registry entry) and three structural smells worth a Phase-2 follow-up.

# Phase 0 — Cartography
|
||
|
||
*Acquisition-grade audit, Phase 0 deliverable. Date: 2026-04-30. Branch: `claude/rebrand-to-magnotia-UWYkg`.*
|
||
|
||
This is a survey, not a verdict. It maps what exists, sizes the surface, and flags every place the README disagrees with the code. Phase 1 (lean-pass) and Phase 2 (architecture conformance) consume this as input.
|
||
|
||
---
|
||
|
||
## 1. Workspace shape
|
||
|
||
| Layer | Path | Notes |
|
||
|---|---|---|
|
||
| Rust workspace root | `Cargo.toml` | `members = ["src-tauri", "crates/*"]`, `resolver = "2"` |
|
||
| Tauri app crate | `src-tauri/` | Library `magnotia_lib` + binary `magnotia` |
|
||
| Library crates | `crates/*` (×9) | See §3 |
|
||
| MCP standalone binary | `crates/mcp/` | Bin `magnotia-mcp` (separate process from main app) |
|
||
| Svelte frontend | `src/` | SvelteKit, Svelte 5 runes, Tailwind 4 |
|
||
| Static assets | `static/`, `src-tauri/icons/`, `src-tauri/resources/` | |
|
||
|
||
**Binaries shipped (2):** `magnotia` (Tauri app), `magnotia-mcp` (stdio MCP server).
|
||

|
||
|
||
## 2. Lines of code
|
||
|
||
| Area | LOC | Files |
|
||
|---|---:|---:|
|
||
| `crates/` (Rust, all 9 crates) | 13,261 | 52 |
|
||
| `src-tauri/` (Rust) | 8,330 | 27 |
|
||
| Frontend (Svelte/TS/JS, excl. design-system) | 15,192 | ~80 |
|
||
| `src/design-system/` (reference kit, not live code) | 1,412 | — |
|
||
| **Total active** | **~36,800** | |
|
||
|
||
### Largest files (top complexity candidates)
|
||
|
||
| LOC | File |
|
||
|---:|---|
|
||
| 2,534 | `crates/storage/src/database.rs` |
|
||
| 2,250 | `src/lib/pages/SettingsPage.svelte` |
|
||
| 1,737 | `src-tauri/src/commands/live.rs` |
|
||
| 1,185 | `crates/storage/src/migrations.rs` |
|
||
| 1,081 | `src/lib/pages/DictationPage.svelte` |
|
||
| 897 | `src/lib/pages/HistoryPage.svelte` |
|
||
| 790 | `src-tauri/src/commands/paste.rs` |
|
||
| 735 | `crates/transcription/src/streaming/rms_vad.rs` |
|
||
| 725 | `src/lib/pages/TasksPage.svelte` |
|
||
| 720 | `src-tauri/src/commands/models.rs` |
|
||
| 697 | `src/lib/stores/page.svelte.ts` |
|
||
|
||
> **Phase 1 candidate.** `database.rs` (2.5k), `SettingsPage.svelte` (2.25k), and `live.rs` (1.7k) are each large enough to deserve a structural review in isolation. HANDOVER.md already flags `SettingsPage` as needing decomposition into 7 progressive-disclosure groups.

|
||
## 3. Crate inventory
|
||
|
||
| Crate | LOC | Files | `pub` items (lib.rs / total) | Tests |
|
||
|---|---:|---:|---:|---:|
|
||
| `magnotia-core` | 1,212 | 9 | 10 / 104 | 16 |
|
||
| `magnotia-audio` | 1,533 | 8 | 14 / 38 | 14 |
|
||
| `magnotia-transcription` | 2,617 | 12 | 13 / 51 | 51 |
|
||
| `magnotia-llm` | 1,330 | 6 | 27 / 56 | 17 |
|
||
| `magnotia-ai-formatting` | 1,502 | 6 | 9 / 21 | 47 |
|
||
| `magnotia-storage` | 3,771 | 4 | 6 / 69 | 60 |
|
||
| `magnotia-hotkey` | 632 | 3 | 5 / 14 | 4 |
|
||
| `magnotia-cloud-providers` | 80 | 2 | 2 / 3 | 2 |
|
||
| `magnotia-mcp` | 584 | 2 | 8 / 8 | 9 |
|
||
| `src-tauri` (`magnotia` + `magnotia_lib`) | 8,330 | 27 | n/a | 67 |
|
||
| **Total** | **21,591** | | | **287** |
|
||
|
||
**Outliers worth a Phase-2 look:**
|
||
- `magnotia-core` exposes 104 public items — high for a "shared types" crate; likely leakage of internals.
|
||
- `magnotia-storage` exposes 69 public items across only 4 files; the file split is suspect (2.5k-line `database.rs`).
|
||
- `magnotia-cloud-providers` is 80 LOC and 3 public items — README calls it "empty scaffolding" (verified: just an in-memory keystore + env-var fallback). Either grow it or remove it; it currently earns nothing.
|
||
|
||
---
|
||
|
||
## 4. Crate dependency graph
|
||
|
||
```
|
||
magnotia-core ──┬─→ magnotia-audio
|
||
├─→ magnotia-transcription
|
||
├─→ magnotia-llm ──→ magnotia-ai-formatting
|
||
├─→ magnotia-cloud-providers
|
||
├─→ magnotia-hotkey
|
||
└─→ magnotia-storage ──→ magnotia-mcp
|
||
|
||
magnotia (src-tauri)
|
||
└─→ all 8 library crates (NOT magnotia-mcp — separate binary)
|
||
```
|
||
|
||
**Observations:**
|
||
- `magnotia-core` is the workspace floor; nothing depends on it depending on something else. Good.
|
||
- DAG is clean — no cycles, no upward dependencies.
|
||
- `magnotia-mcp` correctly depends only on `magnotia-storage` (its sole job is to read the SQLite DB). The Tauri app does **not** depend on it, confirming the "separate process" claim in the README.
|
||
- `magnotia-ai-formatting` depends on both `core` and `llm`. Reasonable.
|
||
|
||
> **Phase 2 will verify:** every `pub` item in the leaf crates (`audio`, `transcription`, `llm`, `storage`, `hotkey`) has at least one external consumer. Internal-only items shouldn't be `pub`.
|
||
|
||
---
|
||
|
||
## 5. External surfaces
|
||
|
||
### 5.1 Tauri commands
|
||
|
||
**102 `#[tauri::command]` attributes** across **22 of 25** modules in `src-tauri/src/commands/`.
|
||
- `power.rs` and `security.rs` are utility modules (no commands; helpers only).
|
||
- `mod.rs` is the registry.
|
||
|
||
| Module | # commands | Module | # commands |
|
||
|---|---:|---|---:|
|
||
| `tasks` | 12 | `intentions` | 5 |
|
||
| `models` | 12 | `audio` | 4 |
|
||
| `llm` | 10 | `tts` | 3 |
|
||
| `profiles` | 9 | `transcription` | 3 |
|
||
| `transcripts` | 8 | `paste` | 3 |
|
||
| `windows` | 8 | `update` | 2 |
|
||
| `diagnostics` | 6 | `rituals` | 2 |
|
||
| `hotkey` | 5 | `live` | 2 |
|
||
| | | `hardware` | 2 |
|
||
| | | `feedback` | 2 |
|
||
| | | `nudges`, `meeting`, `fs`, `clipboard` | 1 each |
|
||
|
||
**Every one of these is a trust boundary** — Phase 4 (security) will audit input validation per command.
|
||
|
||
### 5.2 MCP tools (read-only stdio)
|
||
|
||
Confirmed in `crates/mcp/src/lib.rs`:
|
||
- `list_transcripts`
|
||
- `get_transcript`
|
||
- `search_transcripts`
|
||
- `list_tasks`
|
||
|
||
The `init_readonly` connection mode in `magnotia-storage` is opened at OS level (`SQLITE_OPEN_READONLY`), per `crates/mcp/src/main.rs:18` — Phase 4 will confirm with a write-attempt test.
|
||
|
||
### 5.3 Frontend route surface
|
||
|
||
| Route | Purpose | Layout |
|
||
|---|---|---|
|
||
| `/` | Main dictation shell | `+layout.svelte` (sidebar + chrome) |
|
||
| `/float` | Tasks float window | `+layout@.svelte` (chrome-free) |
|
||
| `/viewer` | Transcript editor | `+layout@.svelte` (chrome-free) |
|
||
| `/preview` | Live transcription overlay | `+layout@.svelte` (chrome-free) |
|
||
|
||
**Pages:** `DictationPage`, `SettingsPage`, `HistoryPage`, `TasksPage`, `FilesPage`, `FirstRunPage`, `ShutdownRitualPage` (7).
|
||
|
||
**Stores:** `page`, `preferences`, `profiles`, `toasts`, `focusTimer`, `llmStatus`, `nudgeBus`, `implementationIntentions`, `completionStats`, `speaker` (10).
|
||
|
||
**Components:** 25 in `src/lib/components/`.
|
||
|
||
**i18n locales:** `en`, `es`, `de` (scaffolding only — most strings are still hard-coded; the migration is incremental per README).
|
||
|
||
### 5.4 Model registry
|
||
|
||
7 models declared in `crates/core/src/model_registry.rs`:
|
||
- Whisper (6): `whisper-tiny-en`, `whisper-base-en`, `whisper-small-en`, `whisper-distil-small-en`, `whisper-medium-en`, `whisper-distil-large-v3`
|
||
- Parakeet (1): `parakeet-ctc-0.6b-int8`
|
||
|
||
> Moonshine is mentioned in the README's `magnotia-core` description ("Moonshine entries") but **no Moonshine entry exists in the registry**. See §7.
|
||
|
||
---
|
||
|
||
## 6. Test floor
|
||
|
||
| Location | Count |
|
||
|---|---:|
|
||
| `crates/*/src/` (lib tests) | 217 |
|
||
| `crates/*/tests/` (integration) | 3 |
|
||
| `src-tauri/src/` + `src-tauri/tests/` | 67 |
|
||
| **Total** | **287** |
|
||
|
||
Only 3 cross-crate integration tests is light. Per-crate lib tests dominate. Phase 5 (test integrity) will mutation-test the heavy crates (`storage`, `transcription`, `llm`) to grade whether these tests actually pin behaviour.
|
||
|
||
---
|
||
|
||
## 7. README ↔ code drift
|
||
|
||
Items where the README disagrees with the code as-of this audit:
|
||
|
||
| README claim | Reality | Severity |
|
||
|---|---|---|
|
||
| "245 automated lib tests across 10 crates" (line 14) | **287 tests** total (220 lib + 67 src-tauri); 220 lib-only | LOW — undercount (good direction, but stale) |
|
||
| "10 crates" (line 14) | 9 library crates + 1 app crate (`src-tauri`) — depends how you count; technically the workspace has 10 packages | OK if counting `src-tauri`; misleading otherwise |
|
||
| "Commands: audio, clipboard, diagnostics, hotkey, live, llm, meeting, models, paste, power, profiles, tasks, transcription, transcripts, update, windows" (line 95-97) — 16 listed | **22 modules with commands**: README missing `feedback`, `fs`, `intentions`, `nudges`, `rituals`, `tts`. Architecture diagram and §"Tauri commands" table both stale. | **MED** — visible to anyone evaluating the codebase |
|
||
| "18 Tauri command modules" (line 117) | **25 files** in `commands/` (22 with command attrs + `mod`, `power`, `security`) | MED |
|
||
| `magnotia-core` "model registry (Whisper + Parakeet + Moonshine entries)" (line 165) | **No Moonshine entries** in `model_registry.rs`. 6 Whisper + 1 Parakeet only. | **MED** — claims an unimplemented feature |
|
||
| Stores listed: `settings, profiles, tasks, history, taskLists, templates, page, toasts, preferences` (line 202) | Actual stores: `page, preferences, profiles, toasts, focusTimer, llmStatus, nudgeBus, implementationIntentions, completionStats, speaker`. README list is **largely fictional** — there is no `tasks`, `history`, `taskLists`, `templates`, or `settings` store as a separate file. | **HIGH** — describes architecture that doesn't exist |
|
||
| `magnotia-cloud-providers` "BYOK cloud-STT provider stubs… Currently empty scaffolding. When populated: OpenAI-compatible endpoint + Anthropic" (line 172) | Crate has an in-memory API-key store with env-var fallback — not "empty scaffolding". No HTTP code, no provider implementations. | LOW — partial |
|
||
| "Every new workspace crate needs a `description` in its `Cargo.toml`" (line 362, contributing rule) | **`crates/llm/Cargo.toml` has no `description` field.** Self-violation of the contribution rule. | LOW — easy fix |
|
||
| README §"Architecture" Rust crate list spelling (line 102-104) | Correct, but the manual line-break formatting got mangled by the rebrand sweep — visible whitespace inconsistency. | TRIVIAL |
|
||
|
||
> **Phase 0 verdict on documentation truth:** The README is **mostly right but actively misleading in two places** — the stores list and the Moonshine claim. Both will fail an acquirer's first sanity-check (`grep -r "Moonshine" crates/`) and erode trust in the rest of the doc.
|
||
|

|
||
|
||
## 8. HANDOVER files
|
||
|
||
| File | Date | Topic | Status |
|
||
|---|---|---|---|
|
||
| `HANDOVER.md` | 2026-04-25 | Latest session (Phase 9a–9d) | Active reference |
|
||
| `HANDOVER-2026-04-24.md` | 2026-04-24 | Phase 8 close | Historical |
|
||
| `HANDOVER-2026-04-19.md` | 2026-04-19 | Earlier session | Historical |
|
||
| `HANDOVER-2026-04-18.md` | 2026-04-18 | Earlier session | Historical |
|
||
| `HANDOVER-2026-04-17.md` | 2026-04-17 | Earliest in tree | Historical |
|
||
|
||
Five handovers in the repo root is unusual — most projects keep one. Phase 8 (docs truth) will recommend either archiving them under `docs/handovers/` or rotating to a single `HANDOVER.md` with prior content moved.
|
||
|
||
The post-rebrand state: all five handovers were rewritten by today's sweep (line counts identical, words different). They now reference `magnotia` paths but their **content** describes work done under the `kon` / `corbie` names — there's a temporal-vs-naming mismatch a reader has to mentally track. Acquirer-friendly fix: add a one-line note at the top of each historical handover saying "Originally written when the product was named X; references rewritten 2026-04-30."
|
||
|
||
---
|
||
|
||
## 9. Quick wins surfaced (defer to Phase 1, but worth flagging)
|
||
|
||
1. **Add `description` to `crates/llm/Cargo.toml`** — 1-line fix; closes a self-imposed contribution-rule violation.
|
||
2. **Update README stores list** — replace fiction with reality. See §7.
|
||
3. **Remove or implement Moonshine claim** — README, line 165.
|
||
4. **Update README Tauri commands list** — six modules undocumented. See §7.
|
||
5. **Decide on `magnotia-cloud-providers`** — currently 80 LOC of a keystore that two consumers call. Either fold into `magnotia-core::keystore` (it's not provider-specific) or actually grow it. Right now it's a crate that doesn't earn its existence.
|
||
|
||
---
|
||
|
||
## 10. Phase 1 entry plan
|
||
|
||
Based on this cartography, Phase 1 (Lean-pass) should target — in this order — the highest-value, lowest-risk wins:
|
||
|
||
1. `cargo machete` + `cargo udeps` workspace-wide → unused deps kill list.
|
||
2. `knip` on the frontend → unused TS/Svelte modules.
|
||
3. Manual review of the **5 files >1k LOC** for duplicate logic (`SettingsPage.svelte`, `database.rs`, `live.rs`, `migrations.rs`, `DictationPage.svelte`).
|
||
4. Grep audit of `TODO` / `FIXME` / `unimplemented!` / `unwrap()` outside tests → tech-debt log.
|
||
5. Reconcile the §7 README drifts.
|
||
|
||
Estimated time: **1 working day** to deliver Phase 1 in full.
|
||
