EBA Adapter Acceptance Report

Date: May 10, 2026

Scope:

• telegram-eba
• discord-eba
• aiocqhttp-eba
• dingtalk-eba
• lark-eba
• wecom-eba
• wecombot-eba
• wecomcs-eba
• officialaccount-eba

This report follows acceptance-checklist.md. Evidence levels are intentionally strict:

• plugin-e2e-ui: real platform or simulator UI event reached LangBot, standalone runtime, and EBAEventProbe.
• plugin-e2e-protocol: real adapter endpoint event reached LangBot, standalone runtime, and EBAEventProbe, but the event was injected at the platform protocol boundary rather than sent through the UI.
• plugin-e2e-outbound: the plugin called SDK APIs and the resulting bot message was visible on the platform.
• unit: mocked converter/API coverage only.
• blocked: not completed, either because the platform/simulator/client could not trigger it or because a safe disposable fixture was unavailable.
• not-supported: the platform has no equivalent capability.

Summary

Adapter	Status	Honest acceptance summary
Telegram	Partial EBA acceptance	Real Telegram UI covered private text, group mention text, bot invite, inbound private image/file, outbound component sweep, safe SDK APIs, and safe Telegram platform APIs. Real UI inbound voice/quote was not completed in the latest plugin run.
Discord	Partial EBA acceptance	Real Discord UI covered group text, outbound image/file/quote/mention components, safe SDK APIs, and safe Discord platform APIs. Real UI inbound attachment/image/file/reply/mention was not completed. A later UI retry was blocked because the Discord client kept the send button disabled.
OneBot v11 / aiocqhttp	Partial EBA acceptance	Matcha UI covered real group text and outbound supported components/APIs. Multi-component inbound Source/Plain/At/Face/Image/Voice/File/Quote was verified through the real OneBot reverse WebSocket adapter endpoint, but not through Matcha UI upload/send. Matcha blocks file-send and merged-forward APIs.
DingTalk	Partial EBA acceptance	Real DingTalk UI covered private text, emoji-as-text inbound, private inbound image/file, outbound image/file/quote/mention fallback components, safe SDK APIs, and safe DingTalk platform APIs. Real UI inbound voice/quote and group trigger were not completed.
Lark / Feishu	Partial EBA acceptance	EBA adapter structure, self-built/store app config, WebSocket/Webhook mode handling, converters, common APIs, platform APIs, and unit tests are in place. One real LangBot organization WebSocket private text event reached EBAEventProbe; outbound component sweep was visible in Feishu. Latest real UI image/file sends did not reach local plugin evidence, so media receive remains blocked.
WeCom	Partial EBA acceptance	Regular WeCom application-message adapter is split into the EBA directory with manifest, converters, API mixin, platform API map, and unit tests. Private text reached EBAEventProbe through standalone runtime and the real WeCom client; safe plugin APIs passed. Real inbound media and broader event coverage remain pending.
WeComBot	Partial EBA acceptance	WeCom AI Bot is split into the EBA directory with WebSocket long connection mode and optional webhook mode, EBA message/feedback/platform-specific conversion, cache-backed common APIs, platform API map, unit tests, and a direct live probe. Private text, outbound component sweep, safe common APIs, and all declared WeComBot platform APIs reached EBAEventProbe; group, real inbound media, and feedback callback evidence remain pending.
WeCom Customer Service	Partial EBA acceptance	WeCom Customer Service is split into the EBA directory with manifest, converters, API mixin, platform API map, unit tests, docs, and a direct live probe scaffold. Real WeChat customer-side UI text reached EBAEventProbe; plugin outbound text/image and safe cache-backed common APIs passed. Inbound media and platform-specific API live coverage remain pending; later fallback text sends were blocked by WeCom 95001 send msg count limit.
Official Account	Partial EBA acceptance	WeChat Official Account is split into the EBA directory with manifest, converters, cache-backed safe APIs, platform API map, unit tests, and a direct live probe scaffold. Real WeChat Official Account UI private text reached EBAEventProbe; safe cache-backed common APIs and declared platform APIs passed. Proactive outbound send_message is not supported because replies must be tied to inbound webhook windows; inbound image/voice live UI evidence remains pending.

Telegram and DingTalk now have real user-side UI image/file upload evidence in plugin JSONL. Discord and aiocqhttp do not yet have real UI inbound image/file evidence.

Unified Shape Verification

All four adapters deliver common SDK entities to plugins before LangBot core/plugin logic handles the event.

Platform-Specific API Acceptance

Adapter	plugin-e2e verified	Blocked or not reproduced
Telegram	safe chat/admin/member count/chat-action actions	mutating actions and callback-only actions were not repeated
Discord	safe channel/guild/role/typing actions	mutating pin/reaction/invite actions were not repeated in the latest plugin run; inbound attachment paths not completed
aiocqhttp	safe OneBot actions such as status/version/can-send checks	get_group_honor_info unsupported by Matcha; admin/card/title/ban/record/file/forward require better endpoint fixtures
DingTalk	check_access_token; real inbound file produced a file URL in the common File component	separate media-download replay APIs and group actions need a working follow-up fixture

SDK API Acceptance

EBAEventProbe exercised the standalone runtime path for:

• bot discovery and bot info lookup
• send message
• component sweep where enabled
• platform API sweep where enabled
• plugin storage
• workspace storage
• plugin/command/tool/knowledge-base list APIs

The probe logs set ok=true when the sweep completed with only expected unsupported/blocked items. Individual call details are stored in the JSONL evidence files.

Residual Risks And Required Follow-Up

• Discord still requires real UI inbound image/file upload evidence before it can be called media-complete.
• aiocqhttp has rich inbound component evidence only at the OneBot reverse WebSocket boundary; Matcha UI did not provide image/file upload coverage.
• DingTalk group trigger remains unclosed; current evidence is private chat only.
• Lark / Feishu requires a clean follow-up live pass: the latest LangBot organization WebSocket run connected, but UI-sent text/image/file after the loop-scheduling fix did not append plugin events.
• Discord UI retry on May 10, 2026 was blocked by the client keeping the send button disabled even after text was entered.
• Destructive moderation and leave APIs are intentionally blocked until disposable users/groups are available.

Conclusion

The EBA conversion path is implemented and partially proven for the migrated adapters. Telegram and DingTalk now have real UI private-chat image/file inbound evidence. Discord, aiocqhttp, and Lark / Feishu still have explicit UI-level media gaps, so the overall adapter set remains partial acceptance rather than production-complete media acceptance.
