+**How deploys actually work:** `master-ai` is a single git repo. Each cloud app builds from its **own** Gitea
+remote, from the matching subfolder. To ship a change, commit in `master-ai`, then
+`git push <remote> HEAD:main` (e.g. `git push coolify_agent_gitea HEAD:main` for the runner), then trigger the
+Coolify deploy for that app (see `VIBNDEV.md`). `vibn-code` is a nested submodule with its own `.git` — commit &
+push it via its own `origin`. Secret `.env*` files at the repo root are gitignored — never commit them.

-* **Deep-Link Protocol Scheme Resolved**:
-  Fixed `src-tauri/Info.plist` which was still configured with `com.talkcody` / `talkcody`. macOS Launch Services now correctly maps `vibncode://` deep links directly to the local dev app.
-* **Rust Compiling Errors Resolved**:
-  Patched cargo clippy errors in `dashscope.rs`, `openai_responses_protocol.rs`, and `openai_responses_ws.rs` (collapsed match statements and annotated unused structs).
-* **Repositories Synchronized**:
-  Merged, committed, and pushed all updated code:
-  * `vibn-code` pushed to Gitea `origin main`.
-  * `vibn-agent-runner` and `vibn-frontend` modifications pushed to `coolify_agent_gitea` and `coolify_gitea` on branch `frontend-deploy-13`.
+**Read `VIBNCODE_THIN_CLIENT_CHANGES.md` first** — it is the live, prioritized change list with exact files,
+steps, and acceptance criteria for the thin-client conversion, plus a STATUS section of what's done.
+
+**Chat works end-to-end.** A desktop message → `POST /api/projects/:id/agent/sessions` → cloud runner executes
+the Coder agent (Gemini) → output polled back into the Monaco chat. Recent fixes that got it there:
+
+* **Local SQLite was wiping chats (fixed):** `database-service.ts` used `INSERT OR REPLACE INTO projects`, which
+  (via `ON DELETE CASCADE`) deleted the active conversation mid-run. Switched to UPSERT; made `task-service`
+  persistence non-blocking. The cloud is the source of truth; local SQLite is just a cache.
+* **Empty `appPath` broke every run (fixed):** the desktop sent `appPath: ""`; the runner's `/agent/execute`
+  rejects falsy `appPath` with HTTP 400 and does nothing (no logs). Desktop now sends `appPath: "."`.
+* **Agent tools `fetch failed` (fixed, pushed):** the runner's `buildContext()` hardcoded
+  `vibnApiUrl: 'http://localhost:3000'` and an empty `mcpToken`, so tool calls fetched a dead port. Now
+  `/agent/execute` reads `mcpToken` from the body and sets `ctx.vibnApiUrl` (from `VIBN_API_URL`) + `mcpToken`.
+  Pushed to `coolify_agent_gitea/main` — confirm the runner redeploy.
+* **Single model:** desktop model picker restricted to the VibnAI model, relabeled "Gemini 3.5 Flash". The
+  runner's real model is set by `GEMINI_MODEL` env (currently `gemini-3.1-pro-preview`); the desktop label is
+  cosmetic until model-passthrough is wired (CHANGE 4.1 in the change doc).
+
+**Known open items (in the change doc):** the desktop still has a hardcoded `vibn_sk_` API key to remove;
+`/agent/sessions/:id/stop` returns 401 to the desktop (uses browser-session auth, not the workspace key); runner
+early-failures are silently swallowed (failure PATCHes omit the `x-agent-runner-secret` header).
+
+**Earlier (still true):** `vibncode://` deep link scheme is registered in `src-tauri/Info.plist`; Rust clippy is
+treated as errors on commit.
