Merge Risk: 🔵 Low · up to Add the shared environment lock to the new test. The remaining issue is bounded and does not block the net and WebSocket provider migration. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The migration has a meaningful security boundary to review: applications now depend on external network providers for behavior previously available in the bundled implementation. The normal TLS provider retains certificate verification, and no exploitable bypass was established, but provider ownership and socket-handle behavior warrant validation across supported build modes.

Ready to merge once CI is clean (tokio lane L4). It deletes perry-stdlib's bundled net/ws/tls_stream copies (all 35 exports are duplicated by perry-ext-net/ext-ws, which have 196) and routes net and ws to the wrappers in every mode. Default mode: 44 gap tests and the node-suite net+tls are identical. With PERRY_DISABLE_WELL_KNOWN=1 the gap tests go from 4 to 35 passing and the node-suite from 48 to 117. No test gets worse in any mode. Merge this before #11402, which is stacked on it. |

tls_import_routes_net_wrapper before it calls well_known_iteration_set, so the
test’s process-environment read is serialized.

- authoring-guide async one-shot example: import StringHeader / JsString / read_string and define the my_digest stand-in so the snippet compiles. - tls_import_routes_net_wrapper: hold env_lock() across well_known_iteration_set, which reads PERRY_FORCE_WELL_KNOWN.

tokio removal, lane L4. This deletes perry-stdlib's bundled
node:netandwscopies andtls_stream.rs(the TLS stream they drove over tokio sockets), instead of porting them. After this PR, none ofnet/,ws.rs,tls_stream.rsorfetch/abort_bridge.rscontains any tokio. The only tokio left in perry-stdlib iscommon::tokio_bridgeand theperry_ffi_*async shims (async-runtime), andfullis now the only thing that selects them.Base:
mainat f6ad6de, which includes #11277, #11308 and #11337. #11402 (the final tokio cleanup) is stacked on this branch.Port or delete: delete
