Sprint SPRINT_20260415_004_DOCS_runtime_data_plane_real_backend_cutover. - Findings.Ledger: Postgres-backed endpoints (runtime timeline/traces, scoring, vuln-explorer, webhook), unsupported-compat shim, ledger data source, vulnerability detail service. - RiskEngine.WebService: web application factory + runtime wiring tests. - SbomService: rename InMemory -> ManifestBacked metadata repo, add Postgres registry source/ledger/lineage/event/watermark repos + migrations 001 initial schema and 002 runtime durable state. - Scanner: SBOM uploads store + migration 026, scan runtime state + migration 027, persisted scan coordinator, Postgres policy repos, VEX gate query service + controller, reachability evidence migration 022.

Scanner
Container(s): stellaops-scanner-web, stellaops-scanner-worker Slot: 8 (web + worker) | Port: 8444 (web) | Consumer Group: scanner (web) Resource Tier: heavy (web + worker)
Note: Cartographer (Slot 21) has been retired and merged into graph-api (Slot 20). See
src/Graph/README.mdfor the merged service.
Purpose
The Scanner module performs SBOM generation, vulnerability analysis, reachability mapping, and supply-chain security scanning of container images. The web service exposes scan APIs (triage, SBOM queries, offline-kit management, replay commands), while the worker processes scan jobs from Valkey queues through a multi-stage pipeline (analyzers, EPSS enrichment, secrets detection, crypto analysis, build provenance, PoE generation, verdict push).
API Surface
scanner(via Router) — SBOM queries, scan submissions, triage, reachability slices, offline-kit import/export, smart-diff, policy gate evaluationcartographer— RETIRED; merged into graph-api (Slot 20)
Storage
PostgreSQL schema scanner (via ScannerStorage:Postgres); RustFS object store for artifacts (scanner-artifacts bucket)
