+# OfficialAccount EBA Adapter
+
+Adapter directory: `src/langbot/pkg/platform/adapters/officialaccount/`
+
+Manifest name: `officialaccount-eba`
+
+Status: partial migration. Unit/API-shape coverage is present, and private text `plugin-e2e-ui` plus safe API evidence has been verified against the `dev.rockchin.top` Official Account fixture. Proactive outbound `send_message` remains not supported by this adapter because WeChat Official Account replies must be tied to inbound webhook windows.
+
+## Config
+
+| Field | Required | Notes |
+| --- | --- | --- |
+| `webhook_url` | no | Generated by LangBot and copied into the Official Account callback settings. |
+| `token` | yes | WeChat callback token. |
+| `EncodingAESKey` | yes | WeChat message encryption key. |
+| `AppID` | yes | Official Account app ID. |
+| `AppSecret` | yes | Official Account app secret. |
+| `Mode` | yes | `drop` waits for an in-callback reply; `passive` returns the loading text first and queues the answer for the user's next message. |
+| `LoadingMessage` | no | Only used by `passive` mode. |
+| `api_base_url` | no | Optional API base URL for proxy deployments. |
+
+## Events
+
+| Event | Evidence | Notes |
+| --- | --- | --- |
+| `message.received` | plugin-e2e-ui, unit | Text UI message verified through WeChat Official Account on `dev.rockchin.top`; image and voice webhook payloads are covered by unit tests. |
+| `platform.specific` | unit | Subscribe/menu/etc. native events are emitted as structured `PlatformSpecificEvent`. |
+
+## Common APIs
+
+| API | Evidence | Notes |
+| --- | --- | --- |
+| `reply_message` | unit | Queues/passively returns text through the inbound webhook source event. |
+| `get_message` | plugin-e2e-ui, unit | Cached inbound message retrieved by `EBAEventProbe` platform API sweep. |
+| `get_user_info` | plugin-e2e-ui, unit | Cached inbound sender retrieved by `EBAEventProbe` platform API sweep. |
+| `get_friend_list` | plugin-e2e-ui, unit | Cached inbound sender list retrieved by `EBAEventProbe` platform API sweep. |
+| `call_platform_api` | plugin-e2e-ui, unit | Safe diagnostic actions verified through `get_mode` and `get_cached_response_status`. |
+| `send_message` | not-supported | Official Account customer-service proactive messaging is not implemented by the existing SDK adapter; only webhook reply is supported here. |
+
+## Platform APIs
+
+| Action | Evidence | Notes |
+| --- | --- | --- |
+| `get_mode` | plugin-e2e-ui, unit | Returned `{"mode": "drop", "longer_response": false}` in live probe. |
+| `get_cached_response_status` | plugin-e2e-ui, unit | Returned `{"pending": false}` in live probe. |
+
+## Components
+
+| Receive Component | Evidence | Notes |
+| --- | --- | --- |
+| `Source` | plugin-e2e-ui, unit | Uses `MsgId` and `CreateTime`; live UI text message included `Source`. |
+| `Plain` | plugin-e2e-ui, unit | Live UI text message mapped to `Plain`. |
+| `Image` | unit | `PicUrl` and `MediaId` map to common `Image`. |
+| `Voice` | unit | `MediaId` maps to common `Voice`. |
+| `Unknown` | unit | Unsupported message/event types do not crash. |
+| `At`, `AtAll`, `File`, `Quote`, `Face`, `Forward`, mixed chain | not-supported | WeChat Official Account inbound webhook payloads used by the current SDK do not expose these as common structured components. |
+
+| Send Component | Evidence | Notes |
+| --- | --- | --- |
+| `Plain` | unit | Sent as webhook reply text. |
+| `Image`, `Voice`, `File`, `Quote`, `At`, `AtAll`, `Face`, `Forward`, mixed chain | not-supported | Existing SDK reply path is text XML only; non-text components degrade to readable placeholders in tests and are not declared as supported outbound components. |
+
+## Verification Record
+
+Test date: 2026-05-28
+
+Endpoint/simulator: `dev.rockchin.top` with WeChat desktop client and a real subscribed Official Account conversation. The running EBA test stack used SDK standalone runtime ports `5400/5401`, LangBot from `/home/wgc/LangBotxg/LangBotEbaTest`, and `EBAEventProbe`.
+
+Verified UI message: `EBA officialaccount single probe 2026-05-28 16:53`
+
+Observed event/API evidence:
+
+- `MessageReceived`: `bot_uuid=d7c46880-a9f8-431a-9172-5d3e0d663dbc`, `adapter_name=officialaccount-eba`, `chat_type=private`, `chat_id=ovH9L7OW6hNpWZWvp_NMmypVh26w`, `message_chain=[Source, Plain]`.
+- Common safe APIs through probe platform sweep: `get_message`, `get_user_info`, `get_friend_list`.
+- Platform APIs through `call_platform_api`: `get_mode`, `get_cached_response_status`.
+- `send_message` and outbound component sweep returned explicit `NotSupportedError: send_message:official_account_requires_inbound_webhook_reply`, as expected for this adapter.
+
+Standalone runtime command:
+
+```bash
+cd langbot-plugin-sdk
+uv run python -m langbot_plugin.cli.__init__ rt --debug-only --ws-control-port 5400 --ws-debug-port 5401 --skip-deps-check
+```
+
+Probe plugin: `data/plugins/LangBot__EBAEventProbe` when live credentials are available.
+
+Adapter live probe:
+
+```bash
+uv run python -m py_compile tests/e2e/live_officialaccount_eba_probe.py
+OFFICIALACCOUNT_TOKEN=... OFFICIALACCOUNT_ENCODING_AES_KEY=... OFFICIALACCOUNT_APP_SECRET=... OFFICIALACCOUNT_APP_ID=... uv run python tests/e2e/live_officialaccount_eba_probe.py
+```
+
+Evidence JSONL path: `/home/wgc/LangBotxg/LangBotEbaTest/data/temp/officialaccount_eba_plugin_probe.jsonl` for plugin E2E, or `data/temp/officialaccount_eba_probe.jsonl` for direct adapter live probe.
+
+Destructive operations: none.
+
+Blocked items:
+
+- `plugin-e2e-outbound`: proactive `send_message` is not supported for this adapter; Official Account responses must be produced through the inbound webhook reply window.
+- Inbound image and voice live UI evidence remains pending; webhook conversion is covered by unit tests.
