Folds in the Sep 14-15 cycle (Android removal, batch transcribe, library
bulk ops, Debian path) with live test counts and the five open candidates.

+# SHONAR Desktop — Status
+
+Checkpoint for the standalone desktop app. Prepend a new dated section per
+material change; keep history below.
+
+## 2026-09-15 — standalone desktop, Android fully removed
+
+**Verified state (live this session):**
+- HEAD `6599935`, clean tree, single branch `master`, no stashes
+- Backend tests: `78 passed, 1 skipped` (pytest, SQLite) · `ruff check` clean
+- Frontend tests: `39 passed` across 7 gradle suites
+- Engine runs locally on `127.0.0.1:8000` (healthz ok); runtime state in
+  `~/.config/shonar-desktop/` (`engine.db`, `settings.json`)
+
+**What the app is:** Compose Desktop (Kotlin) UI + bundled FastAPI engine
+(SQLite + in-process queue, self-migrating on boot). No Postgres/Redis/Docker,
+no server, no phone component. faster-whisper (Base vendored under
+`models/hf-cache/`, Large v3 downloadable) + an LLM for summaries
+(`openai_compat` or `ollama`).
+
+**Architecture decisions worth keeping:**
+- All Android/phone code deleted (`71b5571`) — desktop is the product. The
+  old server-era source lives on the main repo's `deferred/desktop-server`
+  branch for reference only.
+- Shared code sits at `shared/com/shonar` (no `src/`), pulled in via
+  `srcDir("../shared")` in `app/build.gradle.kts`.
+- Search picks its path by SQL dialect inside `services/search.py` (SQLite
+  substring scan / Postgres tsvector) — intentionally **no** `search_backend`
+  config knob (removed `6599935`; nothing ever read it).
+- Engine endpoint root is `/api/v1` (`/healthz`, `/system/status`, …).
+- Dev loop: `./desktop-dev.sh` (inotifywait restarts app on `.kt`; uvicorn
+  `--reload` for backend). Debian path: `INSTALL-debian.md`.
+
+**Done this cycle (Sep 14–15):** batch transcribe-all with overall +
+per-file stage progress; library multi-select/bulk delete (single delete
+path); queued-file delete/rename; folder picker in-app + path in Settings;
+zoom keys; search-within-recording; click-hit-to-playback; model choice
+narrowed to Base + Large v3; Debian packaging + install guide; standalone
+provisioning with vendored base model.
+
+**Open items / candidates:**
+1. Startup adoption of engine jobs already running (app restart currently
+   orphans them from the UI).
+2. Reuse upload mapping after restart instead of re-uploading.
+3. Investigate the 1 skipped backend test (likely the Postgres-path test).
+4. Confirm Large v3 one-command provisioning on a fresh machine.
+5. Stale-noise cleanup: `~/.config/shonar-desktop/pump-error.log` holds old
+   Android→server upload 404s (pre-desktop pivot); no action taken.
+
+**Known debt:** none blocking. No dead stubs; one former TODO (search
+backend) resolved by deletion.
