 ## Resolved decisions
 
+### Resolve identity once
+
+Each ReleaseKit operation resolves repository directory, selected module
+directory and declaration, semantic version, and complete tag once through
+shared resolution logic. Pass that identity through candidate handling,
+validation, callbacks, publication, builds, receipts, delivery, and evidence.
+Subsystems consume the resolved module and tag. Repository-state, tagged-source,
+and artifact verification continue against that identity through their existing
+guards.
+
+### Simple single-module experience
+
+Ordinary root-module consumers use the new interface's defaults: omitted module
+selection means the repository root, the complete tag equals the semantic
+version, notes use `docs/releases/<version>.md`, and validation and builds run
+from the root module. Shared-file defaults apply with input deduplication.
+Root-tag CI uses the ordinary profile and repository-root tool bootstrap.
+
+Routine use requires no additional configuration fields, module mapping
+declarations, or recurring consumer decisions. A representative root-module
+profile, launcher, and CI workflow remain equally small after migration.
+Consumers supply their existing product facts through the new interface.
+One-time API updates and receipt regeneration belong in the next release's
+migration guidance under the clean-cutover decision below.
