- Per-model success/failure tracking with dynamic item limits
- Proactive compaction when above learned limit
- Auto-retry on finish_reason=length with aggressive re-compaction
- Tested: kimi-k2.6 (27 items) and mimo-v2.5-pro both completed
- All previous fixes included: _ts crash, connection reset, timeout, orphaned fco
