[undivisible]

Hardware iteration found activate rejected before dispatch despite Accessibility permission. This is not missing package provisioning: native capabilities are assembled in memory, omit application, and strict validation rejects its capability row. The existing macOS dispatcher implements it. Advertise application with Pointer delivery and unavailable background support; retain authority and all other auxiliary refusals. Regression failed before the fix and passed after it, stopping before native effects. Local format/clippy/all-feature tests/check and release example build passed; two independent exact-head reviews cleared dece0ba. Actual local activation now reaches Succeeded/ExecutedUnverified and FaceTime runs, but no observable FaceTime surface was returned: composer, calls and media remain unverified. No fleet-signed package, facts file, install or restart is involved.

Summary by CodeRabbit

• New Features
  • macOS capability reporting now includes application actions alongside semantic actions when they support pointer-based interaction without background execution.
• Bug Fixes
  • Application actions with other delivery routes or background support are no longer treated as supported. Background-only application requests remain unsupported, and interactive switching attempts that cannot proceed stop before acting on a target.

Walkthrough

The strict capability check now recognizes the application action with specific delivery and background-support settings. macOS native capabilities include this action. A macOS-only protocol test checks interactive and background-only execution.

Changes: macOS application capability

Layer / File(s)	Summary
Capability recognition and protocol behavior src/lib.rs, tests/protocol.rs	The strict check accepts application only with Pointer delivery and BackgroundSupport::Unavailable. macOS native capabilities include the action. The macOS-only test checks execution outcomes for the accepted capability and rejects the listed alternative capability variants. It also ensures target resolution and dispatch are not reached.

_{A rabbit checks the pointer route,
And finds the background path shut out.
FaceTime waits; the test observes,
Then stops before dispatch moves.
The macOS capability joins the list,
While other variants do not pass the test.}

native_application_capabilities_allow_interactive_but_not_background_dispatch to
assert the application capability reports the expected native delivery route and
background support, and verify the background rejection message matches the
specific reason. Add focused invalid-fact cases for TargetAddressed/Unavailable
