+### Minor Changes
+
+- 6d080f5: Make state construction modes explicit and allow one topology target to replace a retained valued owner atomically.
+
+  Valued builders are no longer callable. Replace `target(value)` and nested `builder(value, ...)` calls with `.decoded(value, ...)`; keep `.from(input, ...)` for schema make input. Plain state-update resolvers now expose the decoded owner as `current` and its construction builder as `owner`, replacing the previous `ancestors` plus `target` pattern.
+
+  Declare a combined transition with `.updating(ownerSelector)`. The resolver must finish destination construction with `.update(...)`, so the owner replacement cannot be omitted:
+
+  ```ts
+  to.local
+    .SavingPlan()
+    .updating(to.branch.Ready)
+    .resolve(({ current, owner, target }) =>
+      target
+        .from({ request })
+        .update(owner.decoded(new Ready({ ...current, notice: null })))
+    )
+  ```
+
+  Transition inspection and retained microsteps now include an `updates` array naming replaced owners.
+
