+- Construct application layers from explicit sources, with standalone provider selection and catalog-owned aircraft classification; controls and voice queries use those instances.
+
 - Let application data and controls receive the same explicit layer catalog; keep standalone defaults and registration-before-restoration ordering.
 
 - Expose existing FIRMS CSV parsing and UTC time-window helpers through a portable package export, with shared contract fixtures.

+### Layer construction
+
+`application/layers` constructs the current catalog from explicit source objects
+and an application AbortSignal. Small `src/app/layers` modules wire existing scene
+services into each family factory. Standalone provider selection lives in
+`src/standalone/layerSources.js`. The construction export has its own checked
+dependency graph, excluding standalone setup and compatibility layer instances.
+
+Both aircraft layers share the catalog's classification registry; launches use
+its satellites and Contacts uses its aircraft, vessels and installations. Data
+registration, controls and voice actions read those same instances. Destruction
+remains the manager's responsibility; classification also observes application
+abort when startup has not reached registration. Scene engines remain page-owned,
+so this change does not introduce multiple simultaneous viewers.
+
+Direct `src/data` compatibility entries retain their old defaults and testing
+exports. Browser regression probes use the registered instance's testing surface
+to avoid accidentally inspecting an unused compatibility instance. Existing source
+setters apply only to compatibility instances; the normal application supplies
+its sources at construction.

+Application startup constructs fresh layer instances from explicit source objects.
+Standalone composition selects the existing providers. Controls, launch orbit
+lookups, Contacts voice answers and ISS pass queries use the registered catalog.
+Aircraft classification is catalog-owned and cancelled with application teardown;
+scene engines still support one application per page. Compatibility data entrypoints
+remain for direct callers, but normal startup does not configure global sources.

 Application data setup receives an ordered layer catalog and serialization metadata.
 Controls use the same instances. The standalone composition selects the existing
 default catalog, and restoration starts only after all registrations are sealed.
