 ## Security & Configuration Tips
 - Web provider stores creds at `~/.clawdis/credentials/`; rerun `clawdis login` if logged out.
-- Pi/Tau sessions live under `~/.clawdis/sessions/` by default; the base directory is not configurable.
+- Pi sessions live under `~/.clawdis/sessions/` by default; the base directory is not configurable.
 - Never commit or publish real phone numbers, videos, or live configuration values. Use obviously fake placeholders in docs, tests, and examples.
 
 ## Agent-Specific Notes
 - Gateway currently runs only as the menubar app (launchctl shows `application.com.steipete.clawdis.debug.*`), there is no separate LaunchAgent/helper label installed. Restart via the Clawdis Mac app or `scripts/restart-mac.sh`; to verify/kill use `launchctl print gui/$UID | grep clawdis` rather than expecting `com.steipete.clawdis`. **When debugging on macOS, start/stop the gateway via the app, not ad-hoc tmux sessions; kill any temporary tunnels before handoff.**
 - macOS logs: use `./scripts/clawlog.sh` (aka `vtlog`) to query unified logs for subsystem `com.steipete.clawdis`; it supports follow/tail/category filters and expects passwordless sudo for `/usr/bin/log`.
 - Also read the shared guardrails at `~/Projects/oracle/AGENTS.md` and `~/Projects/agent-scripts/AGENTS.MD` before making changes; align with any cross-repo rules noted there.
-- **Multi-agent safety:** do **not** create/apply/drop `git stash` entries unless Peter explicitly asks. Assume other agents may be working; keep unrelated WIP untouched and avoid cross-cutting state changes.
+- SwiftUI state management (iOS/macOS): prefer the `Observation` framework (`@Observable`, `@Bindable`) over `ObservableObject`/`@StateObject`; don’t introduce new `ObservableObject` unless required for compatibility, and migrate existing usages when touching related code.
-- When asked to open a “session” file, open the Pi/Tau session logs under `~/.tau/agent/sessions/clawdis/*.jsonl` (newest unless a specific ID is given), not the default `sessions.json`.

+First Clawdis release post rebrand. This is a semver-major because we dropped legacy providers/agents and moved defaults to new paths while adding a full macOS companion app, a WebSocket Gateway, and an iOS node.
+
+### Bug Fixes
+- macOS: Voice Wake / push-to-talk no longer initialize `AVAudioEngine` at app launch, preventing Bluetooth headphones from switching into headset profile when voice features are unused. (Thanks @Nachx639)
 
 ### Breaking
 - Renamed to **Clawdis**: defaults now live under `~/.clawdis` (sessions in `~/.clawdis/sessions/`, IPC at `~/.clawdis/clawdis.sock`, logs in `/tmp/clawdis`). Launchd labels and config filenames follow the new name; legacy stores are copied forward on first run.
-- Pi/Tau only: `inbound.reply.agent.kind` accepts only `"pi"`, and the agent CLI/CLI flags for Claude/Codex/Gemini were removed. The Pi CLI runs in RPC mode with a persistent worker.
+- Pi only: `inbound.reply.agent.kind` accepts only `"pi"`, and the agent CLI/CLI flags for Claude/Codex/Gemini were removed. The Pi CLI runs in RPC mode with a persistent worker.
 - WhatsApp Web is the only transport; Twilio support and related CLI flags/tests were removed.
 - Direct chats now collapse into a single `main` session by default (no config needed); groups stay isolated as `group:<jid>`.
-- Gateway background helpers were removed; run `clawdis gateway --verbose` under your supervisor of choice if you want it detached.
+- Gateway is now a loopback-only WebSocket daemon (`ws://127.0.0.1:18789`) that owns all providers/state; clients (CLI, WebChat, macOS app, nodes) connect to it. Start it explicitly (`clawdis gateway …`) or via Clawdis.app; helper subcommands no longer auto-spawn a gateway.
+
+### Gateway, nodes, and automation
+- New typed Gateway WS protocol (JSON schema validated) with `clawdis gateway {health,status,send,agent,call}` helpers and structured presence/instance updates for all clients.
+- Optional LAN-facing bridge (`tcp://0.0.0.0:18790`) keeps the Gateway loopback-only while enabling direct Bonjour-discovered connections for paired nodes.
+- Node pairing + management via `clawdis nodes {pending,approve,reject,invoke}` (used by the iOS node and future remote nodes).
+- Cron jobs are Gateway-owned (`clawdis cron …`) with run history stored as JSONL and support for “isolated summary” posting into the main session.
 
 ### macOS companion app
 - **Clawdis.app menu bar companion**: packaged, signed bundle with gateway start/stop, launchd toggle, project-root and pnpm/node auto-resolution, live log shortcut, restart button, and status/recipient table plus badges/dimming for attention and paused states.
 - **On-device Voice Wake**: Apple speech recognizer with wake-word table, language picker, live mic meter, “hold until silence,” animated ears/legs, and main-session routing that replies on the **last used surface** (WhatsApp/Telegram/WebChat). Delivery failures are logged, and the run remains visible via WebChat/session logs.
 - **WebChat & Debugging**: bundled WebChat UI, Debug tab with heartbeat sliders, session-store picker, log opener (`clawlog`), gateway restart, health probes, and scrollable settings panes.
+- **Browser control**: manage clawd’s dedicated Chrome/Chromium with tab listing/open/focus/close, screenshots, DOM query/dump, and “AI snapshots” (aria/domSnapshot/ai) via `clawdis browser …` and UI controls.
+- **Remote gateway control**: Bonjour discovery for local masters plus SSH-tunnel fallback for remote control when multicast is unavailable.
+
+### iOS node
+- New iOS companion app that pairs to the Gateway bridge, reports presence as a node, and exposes a WKWebView “Canvas” for agent-driven UI.
+- `clawdis nodes invoke` supports `canvas.eval` and `canvas.snapshot` to drive and verify the iOS Canvas (fails fast when the iOS node is backgrounded).
+- Voice wake words are configurable in-app; the iOS node reconnects to the last bridge when credentials are still present in Keychain.
 
 ### WhatsApp & agent experience
 - Group chats fully supported: mention-gated triggers (including media-only captions), sender attribution, session primer with subject/member roster, allowlist bypass when you’re @‑mentioned, and safer handling of view-once/ephemeral media.

 - Added `docs/telegram.md` outlining the Telegram Bot API provider (grammY) and how it shares the `main` session. Default grammY throttler keeps Bot API calls under rate limits.

 ### Highlights
-- **Thinking directives & state:** `/t|/think|/thinking <level>` (aliases off|minimal|low|medium|high|max/highest). Inline applies to that message; directive-only message pins the level for the session; `/think:off` clears. Resolution: inline > session override > `inbound.reply.thinkingDefault` > off. Pi/Tau get `--thinking <level>` (except off); other agents append cue words (`think` → `think hard` → `think harder` → `ultrathink`). Heartbeat probe uses `HEARTBEAT /think:high`.

Pi gets `--thinking <level>` (except off); other agents append cue words (`think` → `think hard` → `think harder` → `ultrathink`). Heartbeat probe uses `HEARTBEAT /think:high`.
 - **Group chats (web provider):** Clawdis now fully supports WhatsApp groups: mention-gated triggers (including image-only @ mentions), recent group history injection, per-group sessions, sender attribution, and a first-turn primer with group subject/member roster; heartbeats are skipped for groups.
 - **Group session primer:** The first turn of a group session now tells the agent it is in a WhatsApp group and lists known members/subject so it can address the right speaker.
 - **Media failures are surfaced:** When a web auto-reply media fetch/send fails (e.g., HTTP 404), we now append a warning to the fallback text so you know the attachment was skipped.
-- **Verbose directives + session hints:** `/v|/verbose on|full|off` mirrors thinking: inline > session > config default. Directive-only replies with an acknowledgement; invalid levels return a hint. When enabled, tool results from JSON-emitting agents (Pi/Tau, etc.) are forwarded as metadata-only `[🛠️ <tool-name> <arg>]` messages (now streamed as they happen), and new sessions surface a `🧭 New session: <id>` hint.

 - **Verbose tool coalescing:** successive tool results of the same tool within ~1s are batched into one `[🛠️ tool] arg1, arg2` message to reduce WhatsApp noise.
 - **Directive confirmations:** Directive-only messages now reply with an acknowledgement (`Thinking level set to high.` / `Thinking disabled.`) and reject unknown levels with a helpful hint (state is unchanged).
-- **Pi/Tau stability:** RPC replies buffered until the assistant turn finishes; parsers return consistent `texts[]`; web auto-replies keep a warm Tau RPC process to avoid cold starts.
+- **Pi stability:** RPC replies buffered until the assistant turn finishes; parsers return consistent `texts[]`; web auto-replies keep a warm Pi RPC process to avoid cold starts.
 - **Claude prompt flow:** One-time `sessionIntro` with per-message `/think:high` bodyPrefix; system prompt always sent on first turn even with `sendSystemOnce`.
 - **Heartbeat UX:** Backpressure skips reply heartbeats while other commands run; skips don’t refresh session `updatedAt`; web heartbeats normalize array payloads and optional `heartbeatCommand`.
 - **Control via WhatsApp:** Send `/restart` to restart the launchd service (`com.steipete.clawdis`) from your allowed numbers.

+
+## Network model (the “new reality”)
+
+- **One Gateway per host**. The Gateway is the only process allowed to own the WhatsApp Web session.
+- **Loopback-first**: the Gateway WebSocket listens on `ws://127.0.0.1:18789` by default.
+  - To expose it on your tailnet, set `gateway.bind: "tailnet"` (or run `clawdis gateway --bind tailnet`) and set `CLAWDIS_GATEWAY_TOKEN` (required for non-loopback binds).
+  - The browser Control UI is served from the Gateway at `http://<host>:18789/ui/` when assets are built.
+- **Bridge for nodes**: when enabled, the Gateway also exposes a bridge on `tcp://0.0.0.0:18790` for paired nodes (Bonjour-discoverable). For tailnet-only setups, set `bridge.bind: "tailnet"` in `~/.clawdis/clawdis.json`.
+- **Remote control**: use a VPN/tailnet or an SSH tunnel (`ssh -N -L 18789:127.0.0.1:18789 user@host`). The macOS app can drive this flow.
+- **Wide-Area Bonjour (optional)**: for auto-discovery across networks (Vienna ⇄ London) over Tailscale, use unicast DNS-SD on `clawdis.internal.`; see `docs/bonjour.md`.
+
+## Codebase
+
+- **TypeScript (ESM)**: CLI + Gateway live in `src/` and run on Node ≥ 22.
+- **macOS app (Swift)**: menu bar companion lives in `apps/macos/`.
+- **iOS app (Swift)**: iOS node prototype lives in `apps/ios/`.
 
 ## Quick Start
-Mac signing tip: set `SIGN_IDENTITY="Apple Development: Your Name (TEAMID)"` in your shell profile so `scripts/restart-mac.sh` signs with your cert (defaults to ad-hoc). Debug bundle ID remains `com.steipete.clawdis.debug`.
 
 Runtime requirement: **Node ≥22.0.0** (not bundled). The macOS app and CLI both use the host runtime; install via Homebrew or official installers before running `clawdis`.
 
 ```bash
-# Install
+# From source (recommended while the npm package is still settling)
-npm install -g clawdis
+pnpm install
+pnpm build

-## macOS Companion App (Clawdis.app)
+### Agent workspace + skills
 
-- **On-device Voice Wake:** listens for wake words (e.g. “Claude”) using Apple’s on-device speech recognizer (macOS 26+). macOS still shows the standard Speech/Mic permissions prompt, but audio stays on device.
+Clawdis runs the embedded agent with its working directory set to the agent workspace (default: `~/clawd`, configurable via `inbound.workspace`).
-- **Push-to-talk (Right Option hold):** hold right Option to speak; the voice overlay shows live partials and sends when you release.
+
-- **Config tab:** pick the model from your local Pi model catalog (`pi-mono/packages/ai/src/models.generated.ts`), or enter a custom model ID; edit session store path and context tokens.
+- Workspace files injected into the system prompt: `AGENTS.md`, `SOUL.md`, `TOOLS.md`
-- **Voice settings:** language + additional languages, mic picker, live level meter, trigger-word table, and a built-in test harness.
+- Custom skills: `<workspace>/skills/<skill-name>/SKILL.md` (default: `~/clawd/skills/<skill-name>/SKILL.md`; only this location is scanned)
-- **Menu bar toggle:** enable/disable Voice Wake from the menu bar; respects Dock-icon preference.

-Bot-mode support (grammY only) shares the same `main` session as WhatsApp/WebChat, with groups kept isolated. Text and media send work via `clawdis send --provider telegram`.

Webhook mode: `--webhook --port … --webhook-secret … --webhook-url …` (or register via BotFather). See `docs/telegram.md` for setup and limits.

+## Clawdis Node (Android) (internal)
+
+Modern Android node app: connects to the **Gateway-owned bridge** (`_clawdis-bridge._tcp`) over TCP and exposes **Canvas + Chat + Camera**.
+
+Notes:
+- The node keeps the connection alive via a **foreground service** (persistent notification with a Disconnect action).
+- Chat always uses the shared session key **`main`** (same session across iOS/macOS/WebChat/Android).
+- Supports modern Android only (`minSdk 31`, Kotlin + Jetpack Compose).
+
+## Open in Android Studio
+- Open the folder `apps/android`.
+
+## Build / Run
+
+```bash
+cd apps/android
+./gradlew :app:assembleDebug
+./gradlew :app:installDebug
+./gradlew :app:testDebugUnitTest
+```
+
+`gradlew` auto-detects the Android SDK at `~/Library/Android/sdk` (macOS default) if `ANDROID_SDK_ROOT` / `ANDROID_HOME` are unset.
+
+## Connect / Pair
+
+1) Start the gateway (on your “master” machine):
+```bash
+pnpm clawdis gateway --port 18789 --verbose
+```
+
+2) In the Android app:
+- Open **Settings**
+- Either select a discovered bridge under **Discovered Bridges**, or use **Advanced → Manual Bridge** (host + port).
+
+3) Approve pairing (on the gateway machine):
+```bash
+clawdis nodes pending
+clawdis nodes approve <requestId>
+```
+
+More details: `docs/android/connect.md`.
+
+## Permissions
+
+- Discovery:
+  - Android 13+ (`API 33+`): `NEARBY_WIFI_DEVICES`
+  - Android 12 and below: `ACCESS_FINE_LOCATION` (required for NSD scanning)
+- Foreground service notification (Android 13+): `POST_NOTIFICATIONS`
+- Camera:
+  - `CAMERA` for `camera.snap` and `camera.clip`
+  - `RECORD_AUDIO` for `camera.clip` when `includeAudio=true`

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
