feat: search result feedback loop with grab detection

[menottim]

Summary

• FeedbackCheckService: polls Sonarr/Radarr command statuses after search runs to detect grabs
• Scheduled feedback: one-shot APScheduler job fires 15 min after search completion (configurable)
• Grab tracking: updates LibraryItem.grabs_confirmed and last_grab_at on confirmed grabs
• Metadata enrichment: search_metadata entries annotated with grab_confirmed flag

New files

• src/splintarr/services/feedback.py — FeedbackCheckService
• tests/unit/test_feedback.py — 10 tests

Test plan

• 113 passed (10 new feedback + 103 existing)
• Manual: trigger search, wait 15 min, verify command statuses polled
• Manual: verify LibraryItem grabs_confirmed incremented

Code review

Found 1 issue:

1. Three log statements in the feedback check path are missing the required instance_id context field, even though instance_id is in scope at each call site. CLAUDE.md says "Always include relevant correlation fields: instance_id for any instance-scoped operation" and "queue_id for search queue operations".

   • _execute_feedback_check logs feedback_check_execution_failed with history_id but omits the instance_id parameter:
     

     splintarr/src/splintarr/services/scheduler.py

     Lines 455 to 457 in 959bfcf

     	except Exception as e:
     	logger.error("feedback_check_execution_failed", history_id=history_id, error=str(e))
     	finally:

   • execute_queue logs feedback_check_schedule_failed with only error, omitting both queue_id and instance_id which are in scope:
     

     splintarr/src/splintarr/services/search_queue.py

     Lines 219 to 221 in 959bfcf

     	except Exception as e:
     	logger.warning("feedback_check_schedule_failed", error=str(e))

   • check_search_results logs feedback_check_command_failed with command_id but omits instance_id:
     

     splintarr/src/splintarr/services/feedback.py

     Lines 138 to 143 in 959bfcf

     	logger.warning(
     	"feedback_check_command_failed",
     	command_id=command_id,
     	error=str(e),
     	)
     	entry["grab_confirmed"] = None # unknown
