Subject: [PATCH 001/133] feat(channel): add QQ Bot channel adapter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add @qwen-code/channel-qqbot package implementing QQ Bot WebSocket
Gateway connection via the official QQ Bot API.

Supports:
- WebSocket Gateway (HELLO/IDENTIFY/HEARTBEAT/DISPATCH/RECONNECT)
- C2C single chat (C2C_MESSAGE_CREATE)
- Group @mention (GROUP_AT_MESSAGE_CREATE) — code path exists, unverified
- Streaming output via msg_id + msg_seq multi-block sending
- Auto-reconnect with exponential backoff
- Sandbox environment toggle

TODO (technical debt acknowledged):
- Group chat not verified end-to-end
- Single-file architecture (should split into gateway/send/auth modules
  like weixin channel)
- No tests (weixin has send.test.ts + media.test.ts)
- No typing indicator (onPromptStart/onPromptEnd not yet implemented)
- No channel instructions injection in connect()
- No structured error types

Closes #5201

Subject: [PATCH 002/133] feat(qqbot): add QR login, group chat support with
 typed events

- Add QR code login via @tencent-connect/qqbot-connector with credential persistence
- Add Intent constants for C2C (1<<12) and GROUP_AT_MESSAGE (1<<25)
- Use QQGroupMessageEvent type in handleGroup instead of cast
- Remove resolved TODO comments for group chat verification
- Add msg_seq to send error log for debugging

- Use bracket notation for Record<string, unknown> to fix TS4111 lint errors
- Add chmodSync(credsFile, 0o600) for credential file permissions
- Implement token refresh at 80% TTL with expires_in tracking
- Fix RECONNECT opcode: use code 4000 + serverRequestedReconnect flag
- Fix connect() Promise: reject on close before READY via connectReject
- Log empty-token case in sendMessage, drain response body on error
- Clear chatTypeMap/replyMsgId/msgSeqMap in disconnect()
- Capture msgId at send-time to avoid race on replyMsgId
- Switch channel-registry.ts to Promise.allSettled (isolated channel failures)
- Add chatId validation (isValidChatId) to prevent SSRF

Subject: [PATCH 007/133] feat(qqbot): add Session Resume + reconnect retry
 resilience

- Support WS session resume (RESUME opcode 6) on reconnect,
  falling back to full IDENTIFY when session is invalid
- Add reconnectWithRetry() loop: retries gateway fetch up to 5x
  with exponential backoff, then schedules 60s fallback retry
  (fixes silent death after GW HTTP 500)
- connect() now retries up to 3 times on initial failure
- Bump maxReconnectAttempts from 10 to 20
- Refresh token before each reconnect attempt

Subject: [PATCH 008/133] fix(qqbot): address review feedback from wenshao

- fixRestoredSessions: use entry.target directly instead of tt.get(undefined)
  (fixes first restored session routing to wrong conversation when 2+ sessions)
- scheduleTokenRefresh: retry in 60s on token refresh failure, not just log
- sendMessage: move saveQQState() after chunk loop, avoid redundant disk I/O
- handleGroup: drop message when group_openid is missing instead of falling
  back to author.id (which would cause 404 on group message send)

- QWEN_HOME: use getGlobalQwenDir() instead of homedir()
- name sanitization: prevent path traversal in file paths
- fetch timeouts: AbortSignal.timeout(15s) on all 3 fetch calls
- TOCTOU: writeFileSync with {mode: 0o600} instead of chmodSync after
- msg_seq gaps: only increment seq on send success, break on failure
- message dedup: seenMessages Map with 5min TTL cleanup timer
- disconnect: set disposed flag + flushQQState sync + clear timers
- heartbeat ACK: track lastHeartbeatAck, force close on 2x interval timeout
- reconnect exhaustion: FATAL log when max attempts reached post-connect
- debounced saveQQState: 500ms debounce, flush on disconnect
- handleGroup: skip [senderName] prefix for slash commands, log for audit
- disposed guard: connectGateway checks disposed before creating WS

 =?UTF-8?q?=E2=80=94=20RESUMED,=20token=20expiry,=20SSRF,=20disposed,=20ty?=

- Handle RESUMED event on RESUME success (start heartbeat, restore sessions)
- Check token expiry before sendMessage, refresh if expired
- Tighten isValidChatId regex (remove . and /) to close path traversal
- Reset disposed flag in connect() for reusability
- Add onPromptStart/onPromptEnd stubs (QQ Bot has no typing API)
- Add robustness comments for splitText surrogate pairs, restoreQQState
  corruption, and senderId identity fragmentation across contexts

Extract HTTP calls, credential I/O, and QR login into separate files
matching the weixin channel's architecture:

- api.ts: fetchAccessToken, fetchGatewayUrl, getApiBase, sendQQMessage
- accounts.ts: getCredsFilePath, loadCredentials, saveCredentials
- login.ts: qrCodeLogin (qrConnect wrapper)

QQChannel.ts drops inline fetch/credential/qrConnect logic and imports
from the new modules. Net -41 lines in the adapter.

Subject: [PATCH 012/133] feat(qqbot): markdown message support (msg_type: 2)

Detect markdown syntax in AI responses and send as msg_type=2
with markdown.content field instead of plain-text msg_type=0.

Detection covers headers, code blocks, bold, italic, strikethrough,
inline code, links, and lists via a single regex.

 (msg_type=7) message support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- types.ts: ArkKV, ArkPayload, FileType, MediaUploadRequest/Response, MediaPayload
- api.ts: uploadQQMedia() — file upload for rich media
- QQChannel.ts: sendArk(chatId, templateId, kv) + sendMedia(chatId, fileType, url, text?)
  - C2C/group upload paths separated (file_info not interchangeable)
  - file_type=4 (文件) blocked for groups per QQ API
  - Embed (msg_type=4) skipped — QQ频道专用, not available for Bot Open Platform

Subject: [PATCH 020/133] feat(qqbot): auto-route !ark / !media commands from
 LLM text via sendMessage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

LLM outputs text — the channel now parses structured commands inline:
  !ark(24, #TITLE#=标题, #META_DESC#=描述)
  !media(image, https://example.com/photo.jpg, caption text)

parseArkCommand / parseMediaCommand extract at sendMessage entry;
normal text/markdown flow unchanged.

Subject: [PATCH 021/133] feat(qqbot): inject channel instructions for
 ark/media commands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sets config.instructions on connect() so the LLM learns about:
  !ark(template_id, key=val, ...) — 3 default templates (23/24/37)
  !media(type, url, [caption])   — image/video/voice/file

Fixes known debt: 'No channel instructions'.

Both features default to false — opt-in via settings.json:

Instructions injected conditionally; command routing gated per-flag.

disposed check, token refresh, chatId validation, sandbox path selection
now in one place. All three methods call resolveRoute() instead of
repeating the same 15-line preamble.

Subject: [PATCH 024/133] chore(qqbot): remove Ark and Media message support

Remove !ark() / !media() text parsing, sendArk/sendMedia methods,
uploadQQMedia, and all related types. The text-parsing approach
was too fragile against LLM output formatting. Only text/markdown
messaging remains.

 This is the opposite of the WeChat channel, which strips all Markdown. You can let the agent use full Markdown with the QQ channel.
 
-## Images and Files
-
-You can send photos and files to the bot in QQ, not just text.
-
-**Photos:** Send an image in the chat and the agent will analyze it using its vision capabilities. This requires a multimodal model — add `"model": "qwen3.5-plus"` (or another vision-capable model) to your channel config.
-
-**Files:** Send a document (PDF, code file, text file, etc.). The bot downloads it and the agent reads it with its file-reading tools. Works with any model.
-
 ## Token Management
 
 Access tokens expire after approximately 2 hours. The channel automatically refreshes them at 80% of their TTL (typically ~1.6 hours). If a refresh fails, it retries after 60 seconds.

Subject: [PATCH 030/133] test(qqbot): add unit tests for send utilities

Add vitest test suite for QQ Bot channel following the weixin channel
testing patterns. Extract isValidChatId, hasMarkdownSyntax, and splitText
as exported module-level functions to enable direct testing.

- 27 tests covering: chatId SSRF validation, Markdown syntax detection, and
  text chunking for QQ's 2000-char message limit
- Add vitest.config.ts and test script to qqbot package
- Register qqbot in root vitest workspace projects

Subject: [PATCH 031/133] test(qqbot): add sendMessage flow tests with mocked
 API

Follow the weixin sendImage test pattern: mock sendQQMessage and
channel-base dependencies to test sendMessage end-to-end.

- C2C/group routing verification
- Markdown msg_type=2 vs plain text msg_type=0
- Markdown rejection fallback to plain text
- Disposed guard and error-stop behavior
- msg_id + msg_seq tracking for multi-chunk streaming

9 new tests, 36 total (all passing)

 =?UTF-8?q?=E2=80=94=20add=20missing=20edge=20cases?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Self-review fixes:
- Fix misleading test name: 'returns early when chatId not in chatTypeMap'
  → 'defaults to C2C path for unknown chatId' (code doesn't return early)
- Add SSRF validation test: sendMessage rejects '../traversal' chatId
- Add network error test: thrown sendQQMessage caught by try/catch
- Add token expiration test: expired token + failed refresh → early return
- Hoist mockFetchAccessToken and set default resolved value in beforeEach
  to prevent silent undefined-access failures in accidental token-refresh paths

39 tests, all passing

Subject: [PATCH 033/133] chore(qqbot): suppress CodeQL ReDoS false positives
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add codeql[js/polynomial-redos] suppression comments for two
regexes flagged by CodeQL:

- hasMarkdownSyntax(): input is LLM-generated reply text,
  never attacker-controlled in Qwen Code Channel context.
- handleGroup(): <@...> prefix is injected by QQ servers;
  openid is assigned by QQ, not attacker-chosen.

Both paths have no practical exploit vector — an adversary
would need to either control an LLM's output or register a
malicious openid with QQ, neither of which is achievable.

 qrConnect return
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- requiredConfigFields: [] — fetchToken() already resolves credentials
  from config → persisted file → QR fallback chain. Blocking at config
  validation prevented QR-code-only users from starting the channel.
- qrCodeLogin(): add bounds check for empty qrConnect() return value.
  If the external library returns an empty array, throw descriptive
  error instead of crashing with TypeError on creds.appId.

Subject: [PATCH 035/133] chore(qqbot): add comments for requiredConfigFields
 and qrConnect guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- index.ts: explain why requiredConfigFields is empty — fetchToken()
  already resolves credentials via config → file → QR fallback chain.
  Requiring appID/appSecret at config level would block QR-only users
  from reaching the fallback through the built-in channel path.

- login.ts: clarify qrConnect() guard is a defensive robustness patch,
  not a response to an observed failure. Verified by removing appID
  from config and running qwen channel start — QR login triggers
  correctly and returns valid credentials.

Subject: [PATCH 040/133] =?UTF-8?q?fix(qqbot):=20address=20PR=20#5902=20re?=
 =?UTF-8?q?view=20=E2=80=94=20concurrency,=20resilience,=20diagnostics?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Critical fixes from review:
- Per-session streamState Map prevents concurrent session buffer clobbering
- Markdown fallback increments msg_seq (was reusing same seq as first attempt)
- Token refresh retries indefinitely with 60s backoff (was giving up after 2 failures, = #5411)
- Close handler stores timer in this.reconnectTimer + logs skip reason (= #5413)
- fixRestoredSessions logs diagnostic when SessionRouter internals aren't found
- READY state restore guarded by coldStart flag (skip on warm reconnect)
- channelType changed to 'qq' to match docs and registry lookup

Suggestions addressed:
- flushQQState uses mode 0o600
- msgSeqMap evicted alongside replyMsgId in periodic cleanup
- saveTimer/replyMsgIdCleanupTimer/seenCleanupTimer .unref()'d
- Slash command log shows only command name, not arguments
- READY log shows session count instead of IDs
- resolveRoute logs on token refresh failure
- reconnectWithRetry inner loop checks disposed after each sleep

Subject: [PATCH 041/133] fix(qqbot): group full-message handling, slash
 command unification, noreply mechanism
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add handleGroupAll with groupAllPolicy (log/keyword/all) and keywordTriggers
- Handle group management events: ADD/DEL_ROBOT, MSG_REJECT/RECEIVE
- Unify slash command detection across handleGroup/GroupAll/C2C
- Default all replies to Markdown (msg_type=2) for @mention support
- Add @mention format instructions and botOpenId injection to model context
- Add noreply mechanism with [可选回复] prefix for non-@ messages
- Use mentions[].is_you for @bot detection instead of string matching
- Preserve raw content with @mention tags for non-slash messages
- Track groupActiveMsgEnabled with persistence
- Pass sender openid/member_openid to model in message prefix

- heartbeatTimer .unref() (already fixed, verified)
- WebSocket READY 30s timeout
- Token refresh delay formula fix
- connect() failure stops token refresh timer
- sleep() .unref()
- reconnectAttempts only on actual gateway connect
- idleFlush & onToolCall errors logged
- msg_seq error log uses sentSeq
- resolveRoute logs on disposed/invalid chatId/token refresh fail
- msgSeqMap TOCTOU: claim seq before await, rollback on failure
- serializeQQState() shared helper
- flushQQState/saveQQState log write errors
- Bridge listener registration logs failure
- idleFlush log shows char count, not content
- handleGroup replyMsgId moved after empty-content guard
- senderName sanitize all Unicode brackets
- handleC2C/handleGroup null-guard event.author
- handleGroupAll strips OPENID tags from LLM input
- handleGroup groupActiveMsgEnabled guard
- startReplyMsgIdCleanup no longer evicts chatTypeMap
- handleC2C chatId no fallback to 'unknown'
- groupAllPolicy runtime validation
- globalSessionsPath standalone mode fix
- keyword matching uses cleanText
- handleGroupAll slash cmd audit log

The model needs <@OPENID> syntax in the input to correctly @mention
other group members in replies. Stripping tags would remove examples
the model needs to learn the correct format.

Subject: [PATCH 054/133] fix(qqbot): use ?? instead of || for buffer fallback
 in onResponseComplete
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The || operator treats empty string '' as falsy, causing a fallback to
_fullText when buffer was already flushed (idleFlush or onToolCall set
it to ''). This produced duplicate messages — the already-sent content
was re-sent as the full response text.

?? only checks null/undefined, so '' is treated as valid (nothing to
send), while null/undefined correctly fall back to _fullText.

Also fix the corresponding test that had the wrong expectation:
when there is no streamState at all, _fullText fallback is correct
behavior (non-streaming response still needs to be sent).

Subject: [PATCH 055/133] fix(qqbot): saveQQState on msgSeqMap error-path
 rollback

Per wenshao review: the HTTP error rollback mutates msgSeqMap but
didn't persist it. If the process crashes before the next successful
send, the rollback is lost and the old (higher) seq is restored on
restart, potentially causing QQ API duplicate-seq rejection.

- Use sanitizeSenderName() instead of ad-hoc \p{Ps}\p{Pe} regex;
  the shared helper strips C0/DEL/C1/bidi controls that the regex misses.
  Set alreadyPrefixed:true in handleInbound envelopes across all 3 handlers.

- Wrap senderName and chatId in sanitizeLogText() for slash command
  audit logs to prevent CR/LF/ANSI escape injection into stderr.

- Check event.mentions in handleGroup before treating messages as slash
  commands. GROUP_AT_MESSAGE_CREATE may fire for @all mentions, not just
  @bot — gate slash detection + replyMsgId on isAtBot.

Content-Transfer-Encoding: 8bit

- Apply sanitizePromptText() to user content in all 3 handlers before
  constructing text templates. alreadyPrefixed:true bypasses ChannelBase's
  re-wrapping block which includes sanitizePromptText — sanitize at source.

- Wrap slash command token in sanitizeLogText() for audit logs to prevent
  ANSI escape injection via crafted command names.

- Add handleGroup test for isAtBot=false (@all) path: verify
  isMentioned=false, replyMsgId not clobbered, text format, alreadyPrefixed.

- Add @all diagnostic log in handleGroup when isAtBot=false for
  observability of silently-dropped messages.

- Export sanitizePromptText from @qwen-code/channel-base.

Subject: [PATCH 060/133] fix(qqbot): .unref(), listener leak, sanitizer tests,
 allowMention config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add .unref() to initial tokenRefreshTimer in scheduleTokenRefresh (Bug).
- Store toolCall listener and remove via bridge.off() in disconnect()
  to prevent listener accumulation on shared bridge (Bug).

- Restore 10 real sanitizer regression tests in send.test.ts using
  vi.importActual — verify sanitizeSenderName/sanitizeLogText handle
  ANSI escapes, bidi overrides, NEL/U+0085, embedded newlines.

- Add allowMention config to QQChannelConfig (default true).
  When false: strip <@OPENID> tags from content in handleGroupAll
  and omit @mention format from system instructions.

Subject: [PATCH 061/133] fix(qqbot): sanitizeLogText missing maxLen arg,
 handleGroup allowMention consistency

- Add missing second argument (64) to 5 sanitizeLogText calls in
  the real sanitizer regression tests (TS2554).

- Respect allowMention config in handleGroup text construction:
  when allowMention !== false, use raw content (preserving @mention
  tags) like handleGroupAll does; when false, use cleanText.
  Fixes inconsistency where handleGroup always stripped tags
  regardless of config.

 persistence for non-@ groups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Pass registerBridgeEvents: true to super() so ChannelBase registers
  the sessionDied listener (router.removeSessionId) — was silently
  dropped because passing router made registerBridgeEvents default false.

- Save chatTypeMap for new groups in handleGroupAll even when isAtBot
  is false, preventing routing loss on crash restart.
  Critical: outbound messages would route to wrong API endpoint.

From: Eric-GoodBoy-Tech <634718930@qq.com>

Subject: [PATCH 065/133] =?UTF-8?q?fix(qqbot):=20R15=20=E2=80=94=20TS2322,?=
 =?UTF-8?q?=20log=20sanitize,=20toolCall=20dup,=20flushQQState,=20connectR?=
 =?UTF-8?q?eject?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix 45 TS2322 dot-notation accesses in events.test.ts: use bracket
  notation for index-signature properties (noPropertyAccessFromIndexSignature).
- Wrap group_openid/op_member_openid in sanitizeLogText() for all
  4 group management event handlers.
- Remove duplicate toolCall listener registration (ChannelBase's
  attachBridgeEvents now handles wiring via registerBridgeEvents:true).
- flushQQState(): use atomic tmp+rename pattern matching saveQQState().
- INVALID_SESSION readyTimeout: call connectReject() to prevent
  promise hang when reconnect attempts exhausted.

Subject: [PATCH 066/133] feat(qqbot): add chatTypes config for
 cron/unsolicited message routing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add chatTypes config to QQChannelConfig (Record<string, 'group'|'c2c'>).
- resolveRoute(): fall back to config.chatTypes when chatTypeMap has
  no entry — essential for cron/scheduled messages to known groups
  that haven't been seen inbound yet.
- Priority: runtime chatTypeMap > config chatTypes > C2C default.

- When markdown passive reply returns HTTP 429, retry as active message
  (no msg_id/msg_seq, plain text msg_type:0).
- If active retry also fails, fall back to existing passive plain text.

- Set verbatimModuleSyntax:false in base/tsconfig.json to strip export type
  from compiled output. Node.js ESM parser does not understand TS-only
  export type syntax — caused 'Unexpected token export' when loading
  extension via import(file://...)

- Add sender OPENID (truncated prefix) to text template in both
  handleGroup and handleGroupAll so the model can distinguish the
  sender's OPENID from the bot's own @mention tag.
- System prompt: clarify that '<@你的BotOPENID>' in a message means
  someone @mentioned the bot.
- Update test expectations for new format.

- Extract d.user.id from gateway READY event as this.botOpenId.
- Append '机器人 OPENID: <实际值>' to instructions after READY
  so the model knows its own OPENID.
- Replace placeholder text with note that OPENID will be provided
  after connection.

Subject: [PATCH 071/133] fix(qqbot): fetch bot OPENID via @me API endpoint
 instead of READY user.id

- READY d.user.id is not the correct bot OPENID per user verification.
- Add fetchBotInfo() to api.ts: GET /users/@me with QQBot auth header.
- Call fetchBotInfo async after READY in all 3 paths (cold start,
  cold start error, warm reconnect). Insert bot OPENID into instructions.
- Remove broken d.user.id extraction and diagnostic log.

Subject: [PATCH 073/133] fix(qqbot): extract bot OPENID from mentions instead
 of @me endpoint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- @me endpoint returns QQ account number (decimal), not the QQ Bot API
  OPENID (32-char uppercase hex) used in group messages.
- Extract botOpenId from event.mentions[].id when is_you is true in
  both handleGroup and handleGroupAll — fires on first @-bot message.
- Remove all fetchBotInfo/@me code from QQChannel.ts.
- Add id field to MentionEvent type in types.ts.

Subject: [PATCH 075/133] fix(qqbot): permanent textChunk listener for
 cron/non-prompt messages

- Add _cronTextHandler permanent listener: catches textChunk events
  from cron-generated ACP agent_message_chunk updates that bypass
  ChannelBase's prompt()-bound listener.
- Use setImmediate to let prompt-path streamState initialize first,
  avoiding double-send during normal conversations.
- Clean up listener in disconnect().

Subject: [PATCH 078/133] fix(qqbot): reorder passive retry chain, add active
 fallback for 400/429
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- New order: markdown passive → plain text passive → active message
  (no msg_id). Previously 429 active retry was interleaved between
  markdown and plain text, breaking sentSeq increment.
- Active fallback after ALL passive attempts fail: roll back msgSeqMap,
  send without msg_id/msg_seq, so expired/rate-limited passive windows
  don't permanently block replies.

Subject: [PATCH 096/133] fix(qqbot): resolve 7 critical review threads from
 wenshao

- #1: groupActiveMsgEnabled guard now allows passive replies (msgId set)
- #2: extractBotOpenId uses member_openid before id for group messages
- #3: onToolCall checks flushingSessions before buffer flush
- #5: idle-flush clears buffer before async send, not in .then()
- #6: pendingStreamDelete only removes streamState on success
- #8: disposed=false set before connect in token-exhaustion path
- #9: connect() resets isReconnecting and reconnectAttempts

Subject: [PATCH 114/133] fix(qqbot): address 4 review threads from PR #5902

- A1: Update msgSeqMap after active retry succeeds (preserve seq continuity)
- A2: Allow @-bot passive replies through when groupActiveMsgEnabled=false
- A3: Only subscribe GROUP_MESSAGE intent for keyword/all policies, not default
- A4: Stop cascade-evicting chatTypeMap/groupActiveMsgEnabled (breaks cron/loops)

Subject: [PATCH 127/133] fix(qqbot): batch fix 19 review threads

- onToolCall: async buffer clear in .then(), restore on failure, flushingSessions guard
- idle-flush: don't discard non-empty buffer on pendingStreamDelete
- handleGroup/handleGroupAll: use event.author.id (global OPENID) as primary senderId
- handleGroup: force isAtBot=true for GROUP_AT_MESSAGE_CREATE events
- saveQQState: add disposed guard
- handleGroup/handleGroupAll: add event.author.bot skip (anti-loop)
- active retry: increment msg_seq to avoid duplicate
- HTTP 429: add MESSAGE DROPPED diagnostic
- extractBotOpenId: store in _botOpenIdSuffix instead of mutating config.instructions
- token refresh: add _reconnectId to prevent stale closure execution
- BRACKET_PROTOCOL_RE: remove start-of-line anchor for mid-line protection
- disconnect: clear flushingSessions/pendingStreamDelete
- setBridge: cronTextHandlerAttached guard
- Tests: chatTypes fallback, concurrency coordination, updated expectations

Subject: [PATCH 128/133] fix(qqbot): batch fix 7 new review threads

- sanitize: restore line-anchored bracket regex (sanitizePromptText)
- handleGroup: finalIsAtBot always true for GROUP_AT_MESSAGE_CREATE
- _botOpenIdSuffix: change to per-group Map to avoid multi-group overwrite
- active retry: msgSeqMap set to nextSeq+1 after successful retry
- prepareGroupMessage: add clarifying comment for bot check
- cron flush: only delete cronBuffer entry if buffer is empty
- onToolCall: clear buffer before async send (idle-flush pattern)

Subject: [PATCH 129/133] fix(qqbot): batch fix 11 review threads

- idle-flush .then(): flush orphaned buffer before pendingStreamDelete
- plain-text fallback: check response.ok, log failure
- onToolCall .catch(): add pendingStreamDelete.delete()
- handleGroupAll: move isDuplicate before prepareGroupMessage
- cron buffer: add retryCount with 3-attempt limit
- policy=log: add stderr diagnostic log
- Remove _botOpenIdSuffixByGroup, derive suffix from botOpenIdByGroup
- handleGroup: remove dead finalIsAtBot=false branches
- handleGroup: correct [atMention=false] to [atMention=true] in text
- idle-flush .catch(): re-arm 2s timer after failed send

Subject: [PATCH 132/133] fix(qqbot): batch fix 5 review threads

- orphaned buffer flush: add .catch() to prevent unhandled rejection
- idleFlush retry .catch(): re-arm 2s timer after restoring buffer
- disconnect(): add cronRetryCount.clear()
- update stale comment about message blocking
- cron retry: schedule retry flush after buffer restore

Subject: [PATCH 133/133] fix(qqbot): batch fix all remaining review threads

- re-arm timer: add flushingSessions guard to prevent duplicate delivery
- wasPending: add log + fire-and-forget on send failure
- re-arm .catch(): log orphaned buffer on give-up
- handleGroup: move isDuplicate before prepareGroupMessage
- connect(): clear stale reconnectTimer on new connection
- Tests: cron retry, streamState isolation, 429 early return,
  msgSeqMap rollback, bot guard, blockStreaming guard,
  cron cleanup, setReplyMsgId cleanup
