Five operational gaps that bite when a connector-backed bot answers questions in real groups: - Single-instance lock: one connector per robot per machine (pid file, stale-lock takeover). Duplicate Stream connections on one clientId get messages load-balanced between them, so the bot answers intermittently (verified live). - Access policy: --allowed-users / --allowed-groups allowlists plus a per-sender rate limit (--user-rate-limit, default 20/min). Every message is an LLM call; without this anyone who can reach the bot can spend on its behalf. - Per-conversation FIFO queue: same-chat messages run in arrival order (follow-ups need the previous turn's --resume session; parallel CLIs racing one session corrupt it); different chats stay parallel. - Picture messages: resolve the callback downloadCode via robot messageFiles/download to a local temp file and hand the path to the agent CLI — error screenshots are the top Q&A inbound and were previously dropped silently. The claudecode persona now permits reading attached files. - --knowledge-dir: lightweight local retrieval (markdown chunking, latin-token + CJK-bigram scoring) prepends top-k matching chunks to each question while the agent keeps running from the clean scratch dir, so replies stay inside DingTalk's AI-assistant response window. All knobs have env mirrors (DWS_ALLOWED_USERS / DWS_ALLOWED_GROUPS / DWS_USER_RATE_LIMIT / DWS_KNOWLEDGE_DIR) for service-style runs. go build ./... clean; go test ./internal/helpers -race passes with new tests for lock/gate/queue/knowledge/media. test/cli_compat, test/scripts and test/unit fail identically on the unmodified base (pre-existing fixture issues).
