- Introduced AGENTS.md, README.md, TASKS.md, and implementation_plan.md for Vexer, detailing mission, responsibilities, key components, and operational notes. - Established similar documentation structure for Vulnerability Explorer and Zastava modules, including their respective workflows, integrations, and observability notes. - Created risk scoring profiles documentation outlining the core workflow, factor model, governance, and deliverables. - Ensured all modules adhere to the Aggregation-Only Contract and maintain determinism and provenance in outputs.
StellaOps Scheduler
Scheduler detects advisory/VEX deltas, computes impact windows, and orchestrates re-evaluations across Scanner and Policy Engine.
Responsibilities
- Maintain impact cursors and queues for re-scan/re-evaluate jobs.
- Expose APIs for policy-triggered rechecks and runtime hooks.
- Emit DSSE-backed completion events for downstream consumers (UI, Notify).
- Provide SLA-aware retry logic with deterministic evaluation windows.
Key components
StellaOps.Scheduler.WebServicecontrol plane.StellaOps.Scheduler.Workerjob executor.- Shared libraries under
StellaOps.Scheduler.*.
Integrations & dependencies
- MongoDB for impact models.
- Redis/NATS for queueing.
- Policy Engine, Scanner, Notify.
Operational notes
- Monitoring assets in ./operations/worker-grafana-dashboard.json & worker-prometheus-rules.yaml.
- Operational runbook ./operations/worker.md.

Epic alignment
- Epic 2 – Policy Engine & Editor: orchestrate incremental re-evaluation and simulation runs when raw facts or policies change.
- Epic 6 – Vulnerability Explorer: feed triage workflows with up-to-date job status, explain traces, and ledger hooks.
- Epic 9 – Orchestrator Dashboard: expose job telemetry, throttling, and replay controls through orchestration dashboards.
