+# Roadmap and requirements
+
+This document consolidates high level requirements and the public roadmap.
+Implementation detail belongs in module architecture and ADRs.
+
+System requirements (high level)
+- Ingest SBOM formats: Trivy JSON, SPDX JSON, CycloneDX JSON.
+- Auto detect SBOM type when missing.
+- Cache and reuse layer analysis for delta scans.
+- Enforce daily quota with HTTP 429 and reset at UTC midnight.
+- Policy engine evaluates YAML rules and supports history.
+- Hot load plugins without service restart.
+- Offline first: no required internet access at runtime.
+
+Non functional requirements (high level)
+- Deterministic outputs and replayability.
+- P95 cold scan and warm scan targets.
+- TLS for inter service traffic.
+- Observability for scan and policy metrics.
+
+Roadmap
+- Public milestones live on the project site.
+
+Feature matrix (summary)
+- Free tier includes core SBOM ingestion, policy, registry, and UI.
+- Reachability DSSE and advanced attestation are staged.
+- Offline update kits and sovereign crypto profiles are first class.
