test(islands): snapshot public API exports and signatures#10218
Merged
Conversation
The islands entry (main.ts) is the public host API for the retained WASM island lifecycle (canReplaceApp/initialize/stopApp). Add a suite that: - snapshots the exported names + runtime arities - pins the exact TypeScript signatures via expectTypeOf (enforced by tsgo, so accidental signature drift fails typecheck) - covers canReplaceApp (single-app-only, side-effect-free probe), stopApp forwarding, and initialize (memoized bootstrap + retry on failure) Also document the host navigation contract and single-app constraint on the exported functions.
