+# Bundled Bun runtime (mac app only)
+
+Date: 2025-12-07 · Owner: steipete · Scope: packaged mac app runtime
+
+## What we ship
+- The mac menu-bar app embeds an **arm64 Bun runtime** under `Contents/Resources/Relay/` only for the packaged app. Dev/CI keep using pnpm+node.
+- Payload: `bun` binary (defaults to `/opt/homebrew/bin/bun`, override with `BUN_PATH=/path/to/bun`), `dist/` output, production `node_modules/`, and the root `package.json`/`pnpm-lock.yaml` for provenance.
+- We prune dev/build tooling (vite, rolldown, biome, vitest, tsc/tsx, @types, etc.) and drop all non-macOS sharp vendors so only `sharp-darwin-arm64` + `sharp-libvips-darwin-arm64` remain.
+
+## Build/packaging flow
+- Run `scripts/package-mac-app.sh` (or `BUN_PATH=/custom/bun scripts/package-mac-app.sh`).
+  - Ensures deps via `pnpm install`, then `pnpm exec tsc`.
+  - Builds the Swift app and stages `dist/`, Bun, and production `node_modules` into `Contents/Resources/Relay/` using a temp deploy (hoisted layout, no dev deps).
+  - Prunes optional tooling + extra sharp vendors, then codesigns binaries and native addons.
+- Architecture: **arm64 only**. Ship a separate bundle if you need Rosetta/x64.
+
+## Runtime behavior
+- `CommandResolver` prefers the bundled `bun dist/index.js <subcommand>` when present; falls back to system `clawdis`/pnpm/node otherwise.
+- `RelayProcessManager` runs in the bundled cwd/PATH so native deps (sharp, undici) resolve without installing anything on the host.
+
+## Testing the bundle
+- After packaging: `cd dist/Clawdis.app/Contents/Resources/Relay && ./bun dist/index.js --help` should print the CLI help without missing-module errors.
+- If sharp fails to load, confirm the remaining `@img/sharp-darwin-arm64` + `@img/sharp-libvips-darwin-arm64` directories exist and are codesigned.
+
+## Notes / limits
+- Bundle is mac-app-only; keep using pnpm+node for dev/test.
+- Packaging stops early if Bun or `pnpm build` prerequisites are missing.
+
+## FAQ
+- **What does `--legacy` do?** When used with `pnpm deploy`, `--legacy` builds a classic flattened `node_modules` layout instead of pnpm's symlinked structure. We no longer need it in the current packaging flow because we create a self-contained hoisted install directly in the temp deploy dir.

+# Telegram (Bot API)
+
+Updated: 2025-12-07
+
+Status: ready for bot-mode use with grammY (long-poll + webhook). Text + media send, proxy, and webhook helpers all ship in-tree.
+
+## Goals
+- Let you talk to Clawdis via a Telegram bot in DMs and groups.
+- Share the same `main` session used by WhatsApp/WebChat; groups stay isolated as `group:<chatId>`.
+- Keep transport routing deterministic: replies always go back to the surface they arrived on.
+
+## How it will work (Bot API)
+1) Create a bot with @BotFather and grab the token.
+2) Configure Clawdis with `TELEGRAM_BOT_TOKEN` (or `telegram.botToken` in `~/.clawdis/clawdis.json`).
+3) Run the relay with provider `telegram` via `clawdis relay:telegram` (grammY long-poll). Webhook mode: `clawdis relay:telegram --webhook --port 8787 --webhook-secret <secret>` (optionally `--webhook-url` when the public URL differs).
+4) Direct chats: user sends the first message; all subsequent turns land in the shared `main` session (default, no extra config).
+5) Groups: add the bot, disable privacy mode (or make it admin) so it can read messages; group threads stay on `group:<chatId>` and require mention/command to trigger replies.
+6) Optional allowlist: reuse `inbound.allowFrom` for direct chats by chat id (`123456789` or `telegram:123456789`).
+
+## Capabilities & limits (Bot API)
+- Sees only messages sent after it’s added to a chat; no pre-history access.
+- Cannot DM users first; they must initiate. Channels are receive-only unless the bot is an admin poster.
+- File size caps follow Telegram Bot API (up to 2 GB for documents; smaller for some media types).
+- Typing indicators (`sendChatAction`) supported; inline reply/threading supported where Telegram allows.
+
+## Planned implementation details
+- Library: grammY is the only client for send + relay (fetch fallback removed).
+- Inbound normalization: maps Bot API updates to `MsgContext` with `Surface: "telegram"`, `ChatType: direct|group`, `SenderName`, `MediaPath`/`MediaType` when attachments arrive, and `Timestamp`; groups require @bot mention by default.
+- Outbound: text and media (photo/video/audio/document) with optional caption; chunked to limits. Typing cue sent best-effort.
+- Config: `TELEGRAM_BOT_TOKEN` env or `telegram.botToken` required; `telegram.requireMention`, `telegram.allowFrom`, `telegram.mediaMaxMb`, `telegram.proxy`, `telegram.webhookSecret`, `telegram.webhookUrl` supported.
+
+Example config:
+```json5
+{
+  telegram: {
+    botToken: "123:abc",
+    requireMention: true,
+    allowFrom: ["123456789"], // direct chat ids allowed (or "*")
+    mediaMaxMb: 5,
+    proxy: "socks5://localhost:9050",
+    webhookSecret: "mysecret",
+    webhookUrl: "https://yourdomain.com/telegram-webhook"
+  }
+}
+```
+- Tests: grammY-based paths in `src/telegram/*.test.ts` cover DM + group gating; add more media and webhook cases as needed.
+
+## Group etiquette
+- Keep privacy mode off if you expect the bot to read all messages; with privacy on, it only sees commands/mentions.
+- Make the bot an admin if you need it to send in restricted groups or channels.
+- Mention the bot (`@yourbot`) or use commands to trigger; we’ll honor `group.requireMention` by default to avoid noise.
+
+## Roadmap
+- ✅ Design and defaults (this doc)
+- ✅ grammY long-poll relay + text/media send
+- ✅ Proxy + webhook helpers (setWebhook/deleteWebhook, health endpoint, optional public URL)
+- ⏳ Add more grammY coverage (webhook payloads, media edge cases)
+
+## Safety & ops
+- Treat the bot token as a secret (equivalent to account control); store under `~/.clawdis/credentials/` with 0600 perms.
+- Respect Telegram rate limits (429s); we’ll add throttling in the provider to stay below flood thresholds.
+- Use a test bot for development to avoid hitting production chats.
