This change adds instrumentation to the compartment mapper that allows it to omit module descriptors from archive compartment maps if they’re not needed to link the archived application.
Security Considerations
None.
Scaling Considerations
Should reduce bundle sizes.
Documentation Considerations
Does not merit attention and one less surprise for bundle size investigators. Noted in NEWS.
Testing Considerations
This change augments the existing test for compartment retention to cover module descriptor collection.
Compatibility Considerations
The change does not add the "retained" property to archived compartment-map.json, so new bundles should remain compatible with older versions of checkBundle. However, I relaxed the schema validator to get an unrelated test for captureCompartmentMap passing, so future deployments of checkBundle will be more lenient.
Closes: #2313
