# TASKS
| Task | Owner(s) | Depends on | Notes |
|---|---|---|---|
|JobCoordinator implementation (create/get/mark status)|BE-Core|Storage.Mongo|DONE – `JobCoordinator` drives Mongo-backed runs.|
|Cron scheduling loop with TimeProvider|BE-Core|Core|DONE – `JobSchedulerHostedService` evaluates cron expressions.|
|Single-flight/lease semantics|BE-Core|Storage.Mongo|DONE – lease acquisition backed by `MongoLeaseStore`.|
|Trigger API contract (Result mapping)|BE-Core|WebService|DONE – `JobTriggerResult` outcomes map to HTTP statuses.|
|Run telemetry enrichment|BE-Core|Observability|DONE – `JobDiagnostics` ties activities & counters into coordinator/scheduler paths.|
|Deterministic params hashing|BE-Core|Core|DONE – `JobParametersHasher` creates SHA256 hash.|
|Golden tests for timeout/cancel|QA|Core|DONE – JobCoordinatorTests cover cancellation timeout path.|
|JobSchedulerBuilder options registry coverage|BE-Core|Core|DONE – added scheduler tests confirming cron/timeout/lease metadata persists via JobSchedulerOptions.|
|Plugin discovery + DI glue with PluginHost|BE-Core|Plugin libs|DONE – JobPluginRegistrationExtensions now loads PluginHost routines and wires connector/exporter registrations.|
|Harden lease release error handling in JobCoordinator|BE-Core|Storage.Mongo|DONE – lease release failures now logged, wrapped, and drive run failure status; fire-and-forget execution guarded. Verified with `dotnet test --no-build --filter JobCoordinator`.|
|Validate job trigger parameters for serialization|BE-Core|WebService|DONE – trigger parameters normalized/serialized with defensive checks returning InvalidParameters on failure. Full-suite `dotnet test --no-build` currently red from live connector fixture drift (Oracle/JVN/RedHat).|
