Share exact signatures
Equivalent standalone routes reuse one deterministic runtime directory.

HASH · SHARE · ISOLATE
Split the runtime.
Keep the lifecycle whole.
Standalone routes now share runtime files only when their capability signatures match. Enhanced-navigation routes intentionally union at the group boundary so layout state and lifecycle hooks keep one ESM identity.
1Family per signature
1Singleton per nav group
0 BStatic route runtime
P1Share only exact needs.
SIGNATURE-KEYED RUNTIME FAMILIES
Share only exact needs.
Preserve ownership boundaries.
Separate differences
Unrelated capabilities no longer alter another route's loaded bytes or cache URL.
Keep navigation whole
Each enhanced-navigation group uses one union family for persistent ownership.
Link directly
Parameter, effect, and native entries import their assigned family without a loader.
Record actual output
Artifact report v2 maps exact route signatures to emitted family files.
Emit nothing
Static routes retain complete HTML and zero client JavaScript.
UPGRADE
Cache runtime capabilities by what routes actually need.
