Scope source-file cleanup fault injection without poisoning enclosing Git
metadata reads. Cover both environments and verify that the retained native
handle stays live through retry, then closes successfully.
Closes#2428.

Verify the static EVM descriptor operation, CLI command, factory and input/output schema bindings with compiler-backed negative assignability checks. Prove SDK duplicate registration and invalid target input fail before provider invocation, preserving named bindings and separate lazy owners.
Validated complete supported single-thread typecheck, focused12 SDK/composition cases plus a targeted2-case provider-spy rerun, static checks, checked pre-push, manual review and all exact-head CI checks. Production behavior/defaults and provider identity remain unchanged. Dynamic third-party module admission and ABI negotiation remain deferred.
