+# Interaction Hub Framework (IHF)
+
+## Overview
+
+`inter-hub` specifies and implements the Interaction Hub Framework (IHF): every meaningful UI widget becomes a governed interaction artifact with a full traceability chain from rendered widget through user interaction, structured feedback, requirement distillation, governance decision, implementation change, to observed outcome.
+
+## Assessment notes
+
+### Discovery
+
+SCOPE.md documents the full traceability chain (widget -> interaction -> feedback -> requirement -> decision -> implementation -> outcome) with explicit in-scope/out-of-scope lists; specs/ and contracts/ dirs back this up. Note: README.md is a stale repo-seed template leftover, not representative — SCOPE.md is authoritative.
+
+### Availability
+
+Haskell/IHP application (App.cabal, Main.hs, Web/Application dirs) with a `.gitea/workflows/deploy.yaml`; runnable/deployable but availability confidence is low pending direct verification of a working build in this sweep.
+
+### 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`
