The shared operational incident endpoint returned HTTP 500 for authoritative firing and recovery observations because Rust RFC3339 strings were bound as PostgreSQL TIMESTAMPTZ parameters. A concurrent systemic-history change also blocked the feedback queue first through an integer/float8 parameter mismatch and then through oversized planning evidence.
198c90b7dea37a07aa6b50acf2cee3d63a7ac5ef, makes PostgreSQL perform the RFC3339 text-to-timestamp conversion and adds an isolated PostgreSQL firing/recovery regression.042e1694cf2bc5ae38173d6e94a47cdfe4ded6af, repairs the systemic-history integer contract and bounds supporting evidence before planning admission.770b7ed74bd1ef3f64a77098989471cb8baa270d, replaces a guessed evidence threshold with the actual remaining planning-prompt budget.3ff263281c9b84f37a3bb8096b34cc492840ae56, calculates overhead with valid minimal JSON matching the real authority-dependent prompt variant.Deployment run 2449 completed successfully for PR #2984. The subsequent main deployment completed successfully for PR #2985. Deployment run 2460 completed successfully for PR #2987, and its exact live queue check detected the invalid-JSON regression. Deployment run 2468 completed successfully for PR #2989.
Production is Ready with zero restarts on exact backend image sha-3ff263281c9b. Across more than two periodic feedback intervals after rollout, logs contained no invalid-JSON, prompt-limit, persistence, or queue-pass error. The queue admitted cycle 72928 for EventHorizon/EventHorizon and durably advanced it from planning to implementation_queued.
At 2026-09-04T10:38:34Z, the host health monitor submitted a fresh recovery observation for email-assistant/mailserver:mail-automation. The API returned HTTP 200 with the original feedback ID 8951 and stable incident fingerprint. Durable case 54239 remains resolved, availability_verified=true, has occurrence count 2, three evidence entries, one deployment entry, and the matching recovery outbox event. The EmailAssistant pod remained 2/2 Ready with both containers at zero restarts and mail automation running since 2026-09-04T06:08:10Z.
