 and reads only `dylink.0` and `uce.abi`; it does not fault the multi-megabyte code
 and data bodies into every new worker. A missing/stale/invalid serialized module
 still reads, validates, compiles, and republishes the complete wasm artifact.
+The proactive compiler also creates that serialization immediately after source

 Cold module compilation and deserialization are host work, so `load_unit()`
 refreshes the epoch deadline before its first guest call. Otherwise a component
 whose compilation outlasted the guest CPU budget would immediately trap in the
