 Target behavior:
 
-- expand the executable import subset beyond the current direct-state and follow-on lanes only when
+- preserve save slices as partial state rather than pretending they reconstruct full live company
-  target resolution and field semantics are statically grounded enough to preserve headless
+  state
-  determinism
+- overlay save-derived packed-event state onto a captured runtime snapshot that already has the
-- add the next imported object families needed to make currently parity-only packed rows executable,
+  needed company roster and other live context
-  starting with company-targeted effects
+- upgrade currently blocked company-targeted packed rows when the overlaid base snapshot provides
+  every referenced company id
 - keep preserving unsupported packed rows as parity summaries instead of guessing executable meaning
 
 Public-model additions for that slice:
 
-- wider target-family summaries only where imported execution can be justified by current static
+- tracked overlay import documents that reference one base snapshot plus one save-slice document
-  evidence
+- runtime-side import outcome labels for packed records so blocked-missing-context and
-- imported company/runtime context needed by the next packed-event target families
+  blocked-unsupported cases stay explicit
-- no shell queue/modal behavior in the runtime core
+- fixture support for generic runtime-import documents, not just snapshots or save slices
 
 Fixture work for that slice:
 
-- save-slice-backed fixtures that prove real packed event records survive import and diff paths
+- overlay-backed fixtures that prove company-targeted packed rows execute deterministically against
-- regression fixtures that lock the current selective executable import boundary and the
+  captured company context
-  unsupported/parity-only counts
+- regression fixtures that lock the before/after boundary between save-slice-only imports and
+  overlay-backed imports
 - state-fragment assertions that lock both packed parity summaries and imported executable records
