+## Semantic Reconciliation
+
+`internal/framework/semanticreconcile` is a domain-neutral strategy used by a
+typed normalize module; it is not itself a selectable stage module. A
+source-backed artifact-family normalizer projects its deterministic records
+into contextual candidates and owned typed record envelopes, supplies its
+chosen prompt identity and resolved LLM profile, and constructs an engine with
+explicit limits. The core filters invalid evidence, assigns contiguous
+request-local integer handles, renders bounded candidate and transcript
+materials, invokes the structured-completion boundary, and assesses the
+returned duplicate groups into a stable non-overlapping plan.
+
+The normalizer then applies that plan through a typed `ApplicationPolicy`. The
+core preserves ungrouped records, contribution order, and provenance while the
+artifact family owns group guards, field and evidence consolidation, durable
+ID derivation, retry and fallback presentation, warnings, and postconditions.
+Request-local handles do not enter the typed value or durable artifact. Fewer
+than two eligible candidates skips model invocation; exceeding a candidate or
+combined-material bound preserves the deterministic result under the family's
+fallback policy. Provider, transport, cancellation, and context-construction
+failures remain execution errors.
+
+The core supplies a conservative generic prompt and the single private
+response schema. A domain prompt may substitute its semantic instructions but
+mounts the core-owned protocol and candidate/transcript presentation assets.
+Prompt, schema, policy, and limit identities participate in manifest metadata
+and checkpoint fingerprints. The generic registrar owns production
+registration of those shared assets; a consuming domain registrar owns only
+its domain prompt.
