+| `services/monitor.ts` | Subreddit ordering, post/comment candidate fetching, reaction/age/gender/seller screening, rejection summaries | Comment sources rotate durably and fetch newest comments; reactions fail closed at recipient-role, confidence, and configured expressed-gender gates; cheap checks run first; preserve exact rejection/deferred counts; listing 404 disables the subreddit. |
 | `reddit/api.ts` | Reddit JSON calls, post/comment parsing, seller/profile evidence, username resolution, error types | All reads must use the coordinator; redact error metadata. |
 | `reddit/request-coordinator.ts` | Process-wide Reddit request spacing and cooldown | Space failed requests too; 429 cooldown is global. |
 | `services/processor.ts` | Source-specific AI preparation and outbound safety | Returns prepared or explicit skip; performs no remote chat send. |

 | `services/recipient-deduplicator.ts` | Global recipient history plus live reservation | Case-insensitive; release failures, commit successes, recover stale claims. |

 | `database/candidate-queue-repository.ts` | Durable candidate state machine, leases, retries, prepared-message replacement, counts, and manual clearing | Mutations require an eligible state or expected worker lease; recover expired/interrupted work; reject active comments admitted under a superseded eligibility policy; operator edits clear AI attribution; manual removals preserve sending leases and terminal audit rows. |
