Module pic 

Direct PocketIC types plus value-adding host-test harness extensions.

Construct and own PocketIc instances normally, then import individual extension traits or prelude for Candid calls, installation, diagnostics, snapshots, fallible startup, and nanosecond time conversion. Native simulator operations remain upstream inherent methods.

PocketIcManagedServer can explicitly own one exact caller-selected server child for a serial suite. No type serializes independent instances or owns PocketIC’s server download/cache policy.
