+The generic registrar is the sole production registration owner for the
+semantic-reconciliation default prompt and private response schema. The
+domain-neutral reconciliation package also exposes only its mandatory protocol
+and candidate/transcript presentation files for domain prompt manifests. D&D
+registry normalizers mount those files while retaining ownership and hashing
+of their D&D system message, semantic instructions, and complete prompt
+declaration. The response schema is therefore registered once even though
+several typed normalizers select it.

 Mounted prompt assets determine a module's fingerprint. The fingerprint hashes
 only the module and shared files explicitly selected by its manifest, so an
 unrelated asset does not invalidate a checkpoint. Schema loaders validate JSON,
 attach identity and digest metadata, make defensive copies, and expose
 diagnostics without raw schema bytes.
 
+Semantic-reconciliation normalizers extend this identity with the shared
+response-schema digest, framework policy version, and complete limit-policy
+digest. Their manifest metadata records the same content-free prompt, schema,
+policy, and limit identities together with domain identity and normalization
+policies. Request-local handles, source material, proposal content, and raw
+asset bytes are not checkpoint metadata.

 Private response schemas validate a model transport envelope. They are not the
 durable artifact schema and should not be documented as an external wire
 contract. Durable formats and compatibility rules remain in the
