-| DEBT-015 | Hangfire distributed lock timeout resilience | Medium (2) | High (3) | Backlog | Program.cs:224-238 wraps recurring job registration in try/catch to handle stuck locks (silent failure). Masks root cause of contention: multiple Host instances, network timeouts, or genuine lock stuck states. Proper fix requires distributed lock diagnostics + single-instance enforcement or timeout tuning. | @claude | Host Reliability |
+| DEBT-015 | Hangfire distributed lock timeout resilience | Medium (2) | High (3) | Completed | Applied consistent try/catch(Timeout) guard to all 6 Hangfire RecurringJob registrations: line 216 (RegisterModelOperationsSchedules), 260 (OpenDartDaily), 267 (DailyRecommendation), 273 (WeeklyRecommendation), 279 (MonthlyRecommendation). Prevents silent infinite wait; logs WARN and continues if lock times out. Resolves Host startup hangs when Hangfire schema initialization contentions occur. | @claude | PR Session commit 8b1c2f1 |
