+# Google Chat Channel Adapter Checklist
+
+Date: 2026-02-16
+Status: completed
+
+## Scope
+
+- Add a first-class Google Chat channel adapter.
+- Support inbound event handling and outbound message replies through Google Chat REST API.
+
+## Completed
+
+- Added `GoogleChatAdapter` in `src/channels/googleChat/adapter.ts`:
+  - inbound webhook handling for `POST /google-chat/events`
+  - optional webhook token validation (`google_chat.webhook_token`)
+  - mention-aware room message gating with DM bypass
+  - optional space allowlist (`allowed_space_names`)
+  - outbound send to `chat.googleapis.com` using service-account OAuth token flow
+  - reply routing via encoded `metadata.replyPeerId`
+- Registered channel exports:
+  - `src/channels/googleChat/index.ts`
+  - `src/channels/index.ts`
+- Added config schema support in `src/config/schema.ts`:
+  - `google_chat.service_account_key_file`
+  - `google_chat.service_account_json`
+  - `google_chat.webhook_token`
+  - `google_chat.allowed_space_names`
+  - `google_chat.require_mention`
+- Wired daemon + gateway integration:
+  - registration in `src/daemon/channels.ts`
+  - gateway Google Chat route handling in `src/gateway/server.ts` (`POST /google-chat/events`)
+- Updated service discovery + docs:
+  - `src/gateway/handlers/services.ts`
+  - `README.md`
+  - `config/default.yaml`
+  - `docs/api/PROTOCOL.md`
+  - redaction coverage for `service_account_json` in `src/cli/shared.ts`
+- Added tests:
+  - `src/channels/googleChat/adapter.test.ts`
+  - `src/config/schema.test.ts` (google_chat schema coverage)
+  - `src/gateway/handlers/services.test.ts` (google_chat service status)
+  - `src/cli/shared.test.ts` (service_account_json redaction)
+
+## Verification
+
+- `pnpm test:run src/channels/googleChat/adapter.test.ts src/config/schema.test.ts src/gateway/handlers/services.test.ts src/cli/shared.test.ts`
+- `pnpm typecheck`
