feat: Implement Runtime Facts ingestion service and NDJSON reader 
- Added RuntimeFactsNdjsonReader for reading NDJSON formatted runtime facts.
- Introduced IRuntimeFactsIngestionService interface and its implementation.
- Enhanced Program.cs to register new services and endpoints for runtime facts.
- Updated CallgraphIngestionService to include CAS URI in stored artifacts.
- Created RuntimeFactsValidationException for validation errors during ingestion.
- Added tests for RuntimeFactsIngestionService and RuntimeFactsNdjsonReader.
- Implemented SignalsSealedModeMonitor for compliance checks in sealed mode.
- Updated project dependencies for testing utilities.

StellaOps Scanner

Scanner analyses container images layer-by-layer, producing deterministic SBOM fragments, diffs, and signed reports.

Latest updates (2025-11-09)

  • Node analyzer now ingests npm/yarn/pnpm lockfiles, emitting DeclaredOnly components with lock provenance. The CLI companion command stella node lock-validate runs the collector offline, surfaces declared-only or missing-lock packages, and emits telemetry via stellaops.cli.node.lock_validate.count.
  • Python analyzer picks up requirements*.txt, Pipfile.lock, and poetry.lock, tagging installed distributions with lock provenance and generating declared-only components for policy. Use stella python lock-validate to run the same checks locally before images are built.
  • Java analyzer now parses gradle.lockfile, gradle/dependency-locks/**/*.lockfile, and pom.xml dependencies via the new JavaLockFileCollector, merging lock metadata onto jar evidence and emitting declared-only components when jars are absent. The new CLI verb stella java lock-validate reuses that collector offline (table/JSON output) and records stellaops.cli.java.lock_validate.count{outcome} for observability.
  • Worker/WebService now resolve cache roots and feature flags via StellaOps.Scanner.Surface.Env; misconfiguration warnings are documented in docs/modules/scanner/design/surface-env.md and surfaced through startup validation.
  • Platform events rollout (2025-10-19) continues to publish scanner.report.ready@1 and scanner.scan.completed@1 envelopes with embedded DSSE payloads (see docs/updates/2025-10-19-scanner-policy.md and docs/updates/2025-10-19-platform-events.md). Service and consumer tests should round-trip the canonical samples under docs/events/samples/.

Responsibilities

  • Expose APIs (WebService) for scan orchestration, diffing, and artifact retrieval.
  • Run Worker analyzers for OS, language, and native ecosystems with restart-only plug-ins.
  • Store SBOM fragments and artifacts in RustFS/object storage.
  • Publish DSSE-ready metadata for Signer/Attestor and downstream policy evaluation.

Key components

  • StellaOps.Scanner.WebService minimal API host.
  • StellaOps.Scanner.Worker analyzer executor.
  • Analyzer libraries under StellaOps.Scanner.Analyzers.*.

Integrations & dependencies

  • Scheduler for job intake and retries.
  • Policy Engine for evidence handoff.
  • Export Center / Offline Kit for artifact packaging.

Operational notes

  • CAS caches, bounded retries, DSSE integration.
  • Monitoring dashboards (see ./operations/analyzers-grafana-dashboard.json).
  • RustFS migration playbook.
