jars a1f3f3f134 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.

Internationalisation

Where you are: Architecture mapFrontend → Internationalisation

Plain English summary. svelte-i18n is wired but coverage is intentionally minimal. The infrastructure (loader, persisted choice, Settings selector) is in place so strings can migrate incrementally. Three locales: English (source of truth), Spanish, German. Most strings still render hardcoded.

At a glance

  • Path: src/lib/i18n/
  • LOC: 73 (index.ts) + 19 lines per locale JSON.
  • Key files:
    • src/lib/i18n/index.ts. Setup, locale detection, public exports.
    • src/lib/i18n/locales/en.json. 19 lines.
    • src/lib/i18n/locales/es.json. 19 lines.
    • src/lib/i18n/locales/de.json. 19 lines.
  • Library: svelte-i18n 4.0.1.

What's in here

index.ts

import { init, register, locale as svelteLocale } from "svelte-i18n";
import { derived, get } from "svelte/store";

export type Locale = "en" | "es" | "de";

export const SUPPORTED_LOCALES: { code: Locale; label: string }[] = [
  { code: "en", label: "English" },
  { code: "es", label: "Español" },
  { code: "de", label: "Deutsch" },
];

const STORAGE_KEY = "magnotia_locale";

register("en", () => import("./locales/en.json"));
register("es", () => import("./locales/es.json"));
register("de", () => import("./locales/de.json"));

function detectInitialLocale(): Locale { /* localStorage → navigator.language → "en" */ }

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 magnotia_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["magnotia_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.
