Root cause of 'no response': auto_heal restart_zhiwei_bot fired whenever
inbound>0 + outbound=0 + errors>0 — which is exactly the normal state while
the bot waits for a slow LLM call (agent tool-use turns take 1-10 min).
Restart killed the in-flight LLM call -> user never got reply -> next cron
cycle saw same state -> restart again. Death loop (fired 22:30,22:35,22:40,
22:45,22:50,23:35).
Fixes:
- CALL_HERMES_TIMEOUT 180s -> 600s (agent tool calls need minutes)
- health(): parse last_inbound/outbound timestamps from journal
- auto_heal: restart bot ONLY if last inbound >600s old with no outbound
since (truly stuck), plus 600s bot-restart cooldown
- slow-but-normal state now logs bot_busy_not_stuck instead of killing
D fix: screenshots were silently dropped (empty body + OOB url).
- register xep_0066, capture msg['oob']['url'] when body empty
- also handle body-as-URL messages (some clients put URL in body)
- download from upload.yoin.fun, OCR via SenseNova (sensenova-6.7-flash-lite)
- inject OCR text as context into LLM call
- config at /home/hmo/.config/mofin/ocr_config.json (outside repo)
- replaces dead node122 GLM-OCR path (host unreachable)
A+B fix: ACK_DELAY 15s -> 120s. 15s fired on every normal LLM
cold-start (20-100s), now only signals genuine hangs.
