IM adapters could keep in-process bridge state after desktop session deletion removed the persisted mapping or after the server no longer had the mapped session. The restore path now validates the stored mapping against bridge memory and the server session before reusing it, then clears stale transient state before creating a replacement session.
Constraint: Issue #574 is intermittent and tied to adapter-created sessions; live reporter Telegram credentials are not available locally.
Rejected: Keep separate recovery checks in each IM adapter | duplicates the same stale-state logic across Telegram, Feishu, WeChat, and DingTalk.
Confidence: high
Scope-risk: moderate
Directive: Do not use bridge.hasSession() as the sole restore check; verify adapter-sessions state and server session existence first.

Telegram Bot API text edits share the same practical message length ceiling as sends, so streaming one growing placeholder can stop exposing new assistant output once the text approaches the limit. The adapter now seals full chunks, opens a fresh editable placeholder, and routes Telegram outbound text through a table-to-bullet formatter for phone readability.
Constraint: Telegram text messages and edits must stay below the platform message limit.
Rejected: Wait until message_complete to split the answer | users still lose streaming visibility during long replies.
Confidence: high
Scope-risk: narrow
Directive: Keep Telegram-specific streaming state in adapters/telegram/format.ts instead of spreading chunk math across message handlers.

The local main sync exposed a flaky WsBridge integration test during coverage: the client-side open event could resolve before the test's server-side connection array observed the connection. The test now waits for the server connection event before sending messages through the captured socket, preserving the FIFO behavior assertion without changing production bridge logic.
Constraint: Worktree validation must cover the latest local main commit before merging back
Rejected: Retry the full quality gate without a code change | the same timing race can recur and hide real merge readiness
Confidence: high
Scope-risk: narrow
Directive: Keep WsBridge integration tests synchronized on server-side connection readiness before using captured sockets

DingTalk AI cards can receive all intermediate text before the final
message_complete event. In that case the message buffer is empty, but
the platform card still needs an explicit terminal update to leave the
inputing state.
Constraint: DingTalk AI cards expose completion separately from buffered text delivery
Rejected: Rely on MessageBuffer.complete only | an empty buffer cannot finalize an active card
Confidence: high
Scope-risk: narrow
Directive: Keep IM terminal-state updates independent from whether a text buffer has pending content

Deleting a desktop session removed the transcript but left IM adapter
chat mappings and live WebSocket state able to point at the old session.
The server now closes the active session socket and removes adapter
mappings after deletion, while adapters refresh the shared session store
before reads so a running process cannot reuse stale in-memory data.
Constraint: Adapter session mappings are shared through adapter-sessions.json across long-running IM processes
Rejected: Patch each adapter ensureSession path separately | shared store refresh fixes all current adapters and avoids drift
Confidence: high
Scope-risk: moderate

The WeChat and DingTalk IM docs were behind the actual desktop adapter flow, especially around QR binding versus user pairing and how users discover slash commands when no platform menu exists. This records the setup path with screenshots and nudges paired users toward /help from the bot itself.
Constraint: DingTalk does not expose the same menu setup path documented for Feishu, so command discovery must work through chat text.
Rejected: Document commands only in VitePress | users may be on mobile when they need the commands.
Confidence: high
Scope-risk: narrow
Directive: Keep IM command docs aligned with adapters/common/format.ts when adding commands.

Text-only IM channels forced users to copy long permission request IDs from mobile chat, which made approval slow and error-prone. This keeps the requestId-based authorization protocol intact while adding short replies for the single-pending-request case and preserving full command fallbacks for ambiguous cases.
Constraint: IM authorization must still resolve through the existing requestId permission_response path
Rejected: Replace request IDs with global numeric IDs | concurrent permission prompts would make numeric IDs ambiguous across chats
Confidence: high
Scope-risk: moderate
Directive: Do not allow short numeric replies when more than one permission request is pending in the chat

This captures the pending worktree fixes before applying them to the
current local main. The changes tighten IM adapter path and credential
handling, preserve retry behavior for failed desktop notifications, and
make Azure/OpenAI provider auth and stop reasons reflect actual runtime
state.
Constraint: Worktree was detached from an older local main with pending uncommitted fixes
Rejected: Merge the detached HEAD directly | would also replay unrelated stale history
Rejected: Leave notification dedupe as fire-and-forget | failed sends consumed retry keys
Confidence: high
Scope-risk: broad
Directive: Keep adapter absolute-path matching constrained to configured work roots
Tested: git diff --check
Not-tested: full quality gate before local main integration
DingTalk can receive interactive card callbacks, but the card UI still depends on a published template, so the adapter now supports a template-backed card path with text commands as the reliable fallback. Telegram and WeChat use the same allow-once, allow-always, and deny semantics so manual authorization behaves the same across platforms.
Constraint: DingTalk button rendering requires an operator-provided interactive card template id
Rejected: Treat the existing AI streaming card template as a permission card | it cannot guarantee visible action buttons
Confidence: high
Scope-risk: moderate
Directive: Do not remove the text approval fallback unless DingTalk card template provisioning is guaranteed

DingTalk uses QR registration to store client credentials, then reuses the existing IM pairing and session bridge. The merged main implementation keeps the existing WeChat QR binding path intact while adding DingTalk as a peer IM platform. The default IM workdir now falls back to the local user working directory so a newly bound chat can start immediately even when recent-project history is empty.
Constraint: Local main already carries WeChat IM, so the merge keeps WeChat config, QR binding, sidecar args, and unbind behavior intact while adding DingTalk.
Rejected: Keep empty defaultProjectDir as project-picker-only | newly bound IM users can hit a dead end with no recent projects.
Confidence: high
Scope-risk: moderate
Directive: Keep IM platform unions synchronized across config, pairing, sidecar args, desktop settings, and docs.

Not-tested: quality:pr full gate was blocked by existing local main CLI-core diff requiring allow-cli-core-change maintainer approval; live post-fix DingTalk second-message delivery was not repeated after the merge.
WeChat needs a QR-paired path instead of bot-token setup, so the adapter layer now includes the iLink protocol calls, desktop pairing UI, server-side bind/unbind APIs, and shared IM command behavior. Empty project history falls back to the user's default work directory so mobile /new works without pre-opening a desktop project.
Constraint: Tencent iLink login returns a URL that the desktop UI must render as a QR image locally
Constraint: IM adapters should keep /new, /projects, status, permission, and default workdir behavior consistent across WeChat, Feishu, and Telegram
Rejected: Require users to paste absolute project paths for first WeChat sessions | mobile onboarding should work from the default user working directory
Confidence: high
Scope-risk: moderate
Directive: Do not change WeChat polling back to overlapping intervals; getupdates is a long-poll endpoint and must remain serialized
Tested: Real WeChat QR scan, inbound /status, outbound reply, and unbind E2E
Tested: bun run check:adapters
Tested: bun run quality:pr
Not-tested: Re-scan live WeChat after the default-workdir fallback tweak; covered by adapter config tests and PR gate
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

This folds together the desktop-side fixes needed before broader rollout.
Session resume no longer deadlocks waiting on init, Mermaid and inline image
output render inside chat, task and sub-agent state stay visible during
execution, local build/release paths are safer, and Feishu/Telegram now expose
lightweight mobile commands (/help, /status, /clear) without adding a new
adapter-specific protocol.
Constraint: Desktop releases must publish updater artifacts from non-draft GitHub releases
Constraint: IM commands need short, phone-friendly responses and low operational complexity
Rejected: Add a dedicated IM command API surface | re-used existing slash commands and session/task REST endpoints to keep adapters thin
Rejected: Wait for task_update push events in WebUI | added low-risk polling because the current frontend ignores that event path
Confidence: medium
Scope-risk: broad
Reversibility: clean
Directive: Keep IM command replies terse and mobile-first, and merge local fallback slash commands when server-provided lists are partial

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
