+# RailianceHosts Infrastructure Provisioning
+
+## Overview
+
+`railiance-infra` (RailianceHosts) is Git-driven automation for provisioning and converging servers on Hosteurope and Hetzner Cloud — Terraform for lifecycle, cloud-init for first boot, Ansible for convergence — with secrets encrypted in-repo via SOPS/age and `inventory/servers.yaml` as the source of truth. It is the S1 Infrastructure Substrate layer of the Railiance OAS Stack.
+
+## Assessment notes
+
+### Discovery
+
+README documents a complete, concrete quickstart (clone, prerequisites, SOPS/age secrets setup, provider setup, terraform apply, ansible convergence) with a specific inventory file (`inventory/servers.yaml`) as source of truth — an unusually complete operational README among the swept repos.
+
+### Availability
+
+Real ansible playbooks, terraform config, and scripts/tools present; has `.forgejo/` CI already; documented as the S1 Infrastructure Substrate layer of the Railiance OAS Stack.
+
+### 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`
