+# Railiance Forge And Artifact Infrastructure
+
+## Overview
+
+`railiance-forge` is being founded to separate source forge, artifact registry, and CI/Actions runner responsibilities from `railiance-apps` and `railiance-enablement`. It directly owns the current Gitea operation and the future Forgejo migration — of particular relevance to REUSE-WP-0019 — though by its own account no live deploy has run yet.
+
+## Assessment notes
+
+### Discovery
+
+README and SCOPE.md explicitly name 'current Gitea operation, future Forgejo migration, container and package registries, Actions runner substrate, artifact lifecycle' as the scope; status noted as 'active forge extraction' with canonical registry operation docs already landed.
+
+### Availability
+
+README explicitly states 'no live Helm deploy or Kubernetes apply was run as part of the move' — documentation and operator targets exist, but this repo is mid-extraction; has .gitea CI (not yet migrated to .forgejo itself, notably, despite owning the migration).
+
+### Completeness
+
+First-pass honest assessment from the REUSE-WP-0017 coverage campaign
+(reuse-surface). No external consumer feedback exists yet; levels reflect
+scope-vs-intent documentation quality, not internal code quality.
+
+### Reliability
+
+No production consumer telemetry exists yet; reliability level is
+intentionally conservative pending REUSE-WP-0019 reuse-telemetry evidence.
+
+## Promotion checklist
+
+- [x] ID follows `capability.<domain>.<name>` pattern
+- [x] Maturity enums match `specs/CapabilityMaturityStandard.md`
+- [x] `external_evidence` is populated separately from `maturity`
+- [ ] Relations reference valid capability IDs (none yet)
+- [x] Index entry added in `registry/indexes/capabilities.yaml`
