 - **Privacy invariant:** message text must **never** leave the device.
-  Detection and the planned translation run locally; **no Chrome Translator, no
-  server, no AI proxy/OpenRouter, no third-party API**. Models are public bytes;
-  only the model is downloaded, never the message.
-- **Phase 2 (next):** Opus-MT (Helsinki, Apache/CC-BY) English-pivot in a
-  **Web Worker**, models self-hosted on Blossom; translations **memory-only**
-  for DMs/crews; sentinel/network-guard test; opt-in auto-translate; DMs + crew
-  chat + spot chat. Per-pack downloads can reveal language choice (not content),
-  so prefer a single/multilingual pack or bundle where practical.
+  **No Chrome Translator, no server, no AI proxy/OpenRouter, no third-party
+  API.** Model files are public bytes; only the model is downloaded, never the
+  message.
+- **Pilot (English ↔ Spanish) is live:**
+  - Models: `Xenova/opus-mt-en-es` + `es-en` (Helsinki Opus-MT, ONNX q8) hosted
+    on the relay VPS at
+    `https://relay.skate-spots.org/models/Xenova/<model>/resolve/main/…`
+    (235 MB total; Caddy `handle_path /models/*` → `/srv/models`, CORS `*`;
+    backup `/etc/caddy/Caddyfile.bak-…`). Both directions verified from the
+    hosted files ("Hello, how are you?" → "Hola, ¿cómo estás?" and back).
+  - Runtime: **`@xenova/transformers` 2.17.2** + ONNX Runtime **1.14** WASM
+    self-hosted in `public/ort/` (37 MB, copied from `onnxruntime-web`), loaded
+    from `../ort/`; worker `src/workers/translate.worker.ts`.
+  - **Hard guard:** `src/lib/translationGuard.ts` permits only model
+    GET/HEAD (no query string) and same-origin `/ort/` assets. The message text
+    only travels via `postMessage` to the local worker.
+    `translation.test.ts` + `translationGuard.test.ts` (9 tests) prove `fetch`
+    is never called with a sentinel message and every other request is blocked.
+  - UI: `src/components/chat/TranslateMessage.tsx` in DMs (`ConversationPage`)
+    and crew chat (`CrewChat`); `TranslationSettings` in Settings → Appearance
+    (auto-translate **off** by default). Translations are **memory-only**;
+    reload/logout clears them. First use downloads ~110 MB per direction with a
+    progress indicator.
+  - i18n: 12 new `translateUi` keys in en/es + all 24 `drift.ts` (check 100%).
+- **Still to do:** add the remaining language pairs via the **English pivot**
+  (`xx→en→target`; Opus-MT packs on the same host), add SpotChat, and measure
+  speed/memory on the APK before a **1.7.2** release.
 - **Keyboard caveat:** a malicious OS keyboard or rooted device is outside the
   app’s control. Warn/recommend a trusted offline keyboard, and avoid the OS
   keyboard for **secrets** (custom secure input / QR / bunker/Amber,
