Feishu CardKit and DingTalk AI Card updates run inside the serialized adapter message path. A hung platform update can prevent the later message_complete event from being handled, leaving mobile IM users stuck on a partial streaming card.
This bounds platform card API calls and gives Feishu a final patch fallback when CardKit finalization fails, so a bad intermediate frame cannot permanently block the chat turn.
Constraint: Feishu and DingTalk card APIs are external network calls without reliable SDK-level deadline guarantees
Rejected: Disable streaming cards entirely | loses the live IM experience for normal fast responses
Confidence: high
Scope-risk: narrow
Directive: Keep IM card platform calls bounded because adapter server messages are serialized per chat
Tested: bun test adapters/feishu/__tests__/streaming-card.test.ts
Tested: bun test adapters/dingtalk/__tests__/ai-card.test.ts
Tested: bun run check:adapters
Tested: bunx tsc -p adapters/tsconfig.json --noEmit
Not-tested: Full bun run verify was interrupted during the coverage lane after dependency setup
Feishu cards used to sit on "正在思考中..." for the entire turn and
then dump everything at message_complete, while Telegram showed the
reasoning and tool calls progressively. Two underlying causes:
1. handleServerMessage ignored `thinking`, `content_start{tool_use}`
and `tool_use_complete` entirely, so nothing was fed into the card
between turns of text output.
2. StreamingCard.performFlush silently set `cardKitStreamActive=false`
on any non-rate-limit error, after which all middle frames were
skipped and only finalize touched the card — exactly the
"long wait → all at once" symptom.
StreamingCard now tracks accumulatedReasoningText and a toolSteps
list, with appendReasoning / startTool / completeTool methods that
trigger throttled flushes like appendText. renderedText composes
tools → reasoning → answer in plain markdown (no blockquotes / lists
that historically tripped Feishu's parser). consecutiveStreamFailures
threshold (3) keeps a single transient error from killing the stream.
terminalText() is used by finalize so the final card holds only the
answer text, matching the Desktop UI's clean post-completion view.
handleServerMessage wires the new events to the existing per-chat
StreamingCard via the streamingCards map (read-only — never
auto-creates cards from thinking/tool events to avoid empty cards
for /clear-style commands).
Test coverage: realistic event-stream regression (thinking → tool_use
→ text → finalize), first-frame-failure recovery, finalize drops
intermediate state, plus per-method tests for the new APIs.

Replace legacy im.message.patch streaming path with a Feishu CardKit
Schema 2.0 pipeline mirroring openclaw-lark's implementation. Desktop
now renders real formatted markdown (headings, tables, code blocks)
instead of literal text, and streaming output updates per chat without
cross-talk.
New modules:
- card-errors.ts: structured Lark SDK error parsing for code 230020
(rate limit -> skip frame) and 230099/11310 (table limit -> disable
CardKit streaming and fall back to settings+update at finalize)
- flush-controller.ts: mutex + needsReflush + long-gap batching
throttler for per-chat flush coordination
- cardkit.ts: thin wrapper over client.cardkit.v1.* (card.create +
im.message.{create,reply} + cardElement.content + card.settings +
card.update), with monotonic sequence and CardKitApiError
- streaming-card.ts: per-chat StreamingCard state machine covering
idle -> creating -> streaming -> finalizing -> completed/aborted,
including patch fallback when CardKit create/send fails
index.ts rewrite:
- replaces MessageBuffer/chatStates/buffers maps with a single
streamingCards Map<chatId, StreamingCard>
- content_start{text}/content_delta create or reuse the card; finalize
runs on message_complete; abort renders a red error card
- /clear and other silent commands stay out of the streaming-card path
so they don't leave empty cards
- all command handlers + normal chat are wrapped in the per-chat
enqueue() serial queue, preventing reply reordering when commands
are fired rapidly
- createSessionForChat() now first resets any stale WS session before
calling connectSession, fixing /projects pick_project leaving the
old session bound to the previous workDir
- normal messages pre-create the card before sendUserMessage so users
see a "☁️ 正在思考中..." loading indicator immediately
- content_start{tool_use} no longer finalizes the current card, letting
one user turn's full text stay in a single card
markdown-style.ts:
- default cardVersion changed from 1 to 2 (Schema 2.0)
- headings H2~H6 demoted to H5, H1 to H4, only when source has H1~H3
- Schema 2.0 <br> padding around headings, tables, code blocks
- stripInvalidImageKeys() drops non-img_* image references
- FEISHU_CARD_TABLE_LIMIT=3 + sanitizeTextForCard() wraps 4th+ table
in a fenced code block to avoid 230099/11310
Tests: 182 pass, 0 fail, 383 expect() calls across 6 files. tsc clean.

Carries forward ~800 lines of in-flight work that existed in the working
tree before the IM-attachment branch was cut. Kept as a single isolated
commit so later attachment work has a clean diff baseline and so this
WIP can be cherry-picked back to main on its own merits.
Contents:
- ws-bridge: per-chat handler chain serialization; sendPermissionResponse
now accepts optional `rule: 'always'` for persistent permits
- feishu/index.ts: permission card rewritten to Schema 2.0 with icon,
cross-dir warning, and ♾️ 永久允许 button; optimizeMarkdownForFeishu
applied to streaming card
- feishu/markdown-style.ts: new Feishu-specific markdown downgrader
- tests: corresponding bun:test coverage

- Resolve bot open_id via /open-apis/bot/v3/info — the SDK's
contact.user.get({user_id: 'me'}) path is invalid on Feishu and
returned 99992351 on every startup.
- Stream replies via interactive cards instead of post messages:
im.message.patch only accepts msg_type=interactive, so the old
path-rich-text placeholder caused "This message is NOT a card"
(230001) on every flush. Added buildStreamingCard helper.
- Add project picker card: one column_set row per project with
[info (name + branch + path) | select button], Schema 2.0,
mobile-friendly path display (~ substitution + middle-truncation),
header subtitle with project count. pick_project actions route
through the existing handleCardAction.
Card patterns verified against openclaw-lark's Schema 2.0 usage in
src/tools/oauth-cards.ts and src/card/builder.ts. 34 unit tests
cover the new card structure and action routing.
Implement IM adapters allowing users to chat with Claude Code from Telegram
and Feishu/Lark. Includes persistent session management (chatId→sessionId
mapping), project selection via /projects command, and a web UI settings page
for configuring bot tokens, allowed users, and default project directory.
Key changes:
- adapters/: Telegram and Feishu adapter scripts with shared common modules
(WsBridge, MessageBuffer, SessionStore, HttpClient, config, formatting)
- Backend: adapterService + REST API (GET/PUT /api/adapters) with secret masking
- Frontend: AdapterSettings page in Settings tab with i18n support
- DirectoryPicker: use React Portal for dropdown to fix overflow clipping
