Refresh host health from the persisted retention-filtered history after batch completion, allowing the existing generation guard to reject stale responses and removing the competing local merge path.
Keep the complete loaded history snapshot, sample only valid non-future recent batches, count seven-day failures independently, ignore disabled accounts in issue counters, and preserve loading and error states across batch completion.
Summarize up to fifty recent batches and current account state into a local host health table with success rates, effective historical throughput, recent failures, last success, and bilingual accessible empty states.
Verify update artifacts with exact metadata and SHA-512, require host-confirmed upload completion before cleanup, harden credentials and backups, improve queue recovery and skipped-state reporting, expand Windows path coverage, and add CI packaging checks.
