+# Semantic Enterprise State Integrity Mapping v0.1
+
+`sourceos-syncd` consumes `semantic-enterprise-v0.1.0` from `SocioProphet/ontogenesis` as a state-integrity mapping surface.
+
+The local fixture is:
+
+- `examples/semantic-enterprise/v0.1/state-integrity-mapping.example.json`
+
+The validator is:
+
+- `tools/validate_semantic_enterprise_state_integrity.py`
+
+## Source release
+
+- Repository: `SocioProphet/ontogenesis`
+- Release/tag: `semantic-enterprise-v0.1.0`
+- Manifest: `manifests/semantic_enterprise_v0_1_manifest.json`
+- Rollup registry: `catalog/semantic_enterprise_v0_1_registry.ttl`
+- Supply-chain module: `Domains/supply-chain.ttl`
+- Named graph fixture: `examples/named-graphs/semantic_sector_named_graphs.ttl`
+
+## State integrity surfaces
+
+The v0.1 mapping covers:
+
+- artifact lineage
+- release provenance
+- repair lineage
+- rollback evidence
+- local-first state context
+- named graph governance
+
+## Semantic bindings
+
+The fixture maps SourceOS state surfaces to Semantic Enterprise concepts:
+
+- `release_artifact` -> `supply-chain:Component`
+- `state_integrity_report` -> `named-graph-governance:CuratedGraph`
+- `repair_plan` -> `supply-chain:MitigationAction`
+- `rollback_evidence` -> `supply-chain:AlternateSource`
+
+## Closure boundary
+
+The mapping distinguishes:
+
+- `inside_source`: Ontogenesis authors semantic source modules and supply-chain scenarios.
+- `outside_state_runtime`: SourceOS syncd maps semantic provenance into local-first state integrity evidence.
+- `boundary_membrane`: release tag, source path, graph URI, trust level, access class, retention policy, and lifecycle phase survive translation.
+- `feedback_surface`: SourceOS repair, rollback, and state reports remain downstream evidence.
+
+## Validation
+
+Run:
+
+```bash
+make validate
+```
+
+or:
+
+```bash
+python3 tools/validate_semantic_enterprise_state_integrity.py
+```
+
+## Parent work
