…I/O rustls session The node:tls server (tls.createServer), the bundled net client's tls.connect/upgradeToTLS and the wss:// connector now handshake through perry_tls_session::TlsSession (new: client and server, over caller-built rustls configs), driven over their existing tokio sockets by crates/perry-stdlib/src/tls_stream.rs, which keeps tokio_rustls's observable contract. perry-stdlib no longer depends on tokio-rustls; the inventory drops that edge (17 -> 16). The sockets stay tokio (group L).

Make external-tls-server enable tls-runtime.
tls already enables tls-runtime, but external-tls-server only enables its dependencies directly. The crate gates both the tls module and tls_stream on tls-runtime (or, for tls_stream, bundled-ws). So external-tls-server alone does not provide the TLS module and dispatch surface its feature comment describes.

Bound poll_write to one pump budget.
TlsStream::poll_write queues the entire input, while TlsSession::pump performs at most 4096 steps. Each WriteTraffic step encrypts at most 16 KiB, so one pump processes at most 64 MiB. The remaining bytes stay in deferred, but poll_write returns Ok(buf.len()).
poll_flush performs only one additional pump. poll_read pumps only after it receives ciphertext. The TLS-backed writers in tls.rs, net/mod.rs, and ws.rs call write_all without flushing. If the peer waits for the complete payload, a write larger than 64 MiB can leave its tail pending while the read side waits for the peer.
The unbounded queue also removes backpressure for large writes. Accept a bounded chunk per poll_write call.

Make ClientHello reassembly incremental to avoid quadratic rescanning.
feed calls client_hello(seen) on every receive. The parser rescans all previous record fragments and rebuilds message each time. TLS handshake messages may span multiple records, and rustls accepts this fragmented input. An unauthenticated peer can therefore cause quadratic CPU work on the shared Tokio runtime before LIMIT is reached.
Keep the parse cursor and reassembled message in Pending so each record fragment is processed once.

…he manifest Two required steps were red on #11036; neither is a defect in what the PR does. `lint :: File size limit` — `crates/perry-stdlib/src/net/mod.rs` was 1968 lines on main and this PR's `js_net_socket_read` + `NET_PENDING_READS` pushed it to 2006, six over `scripts/check_file_size.sh`'s hard 2000-line cap. Split into three sibling modules, re-exported from `mod.rs` with explicit named `use`: value_helpers.rs (247) NaN-boxed JS value/object readers tls_config.rs (358) TLS option parsing + rustls connector construction socket_task.rs (281) the per-socket tokio task and TLS handshake recording mod.rs (1181) handle storage, the FFI surface, the event pump Pure move: every moved item keeps its name, signature, doc comment, attributes and `#[cfg(feature = "tls")]` gating; the only edit is `pub(super)` on the ones `net` still calls. All 18 `#[no_mangle] pub extern "C"` symbols stay in `mod.rs`, verified identical before/after. `net/tls_verifier.rs` needed explicit `rustls` imports in place of its `use super::*;` — the danger-trait names it relied on were re-exported from `mod.rs`, and a glob does not carry them once they move. No path-keyed gate entry moved: `gc_runtime_root_holders.json`'s two entries for this file (`NET_GC_REGISTERED`, `SCRATCH`) both name items that stayed in `mod.rs`; `addr_class_ratchet_baseline.txt`, `addr_class_allowlist.txt`, `raw_handle_debt_files.txt` and `shape_descriptor_census_baseline.json` have no entry for it. All five scripts re-run green, including `raw_handle_debt.py --no-raise-vs origin/main` (no relocation to declare). `cargo-test :: Run cargo test` — `perry-codegen`'s `manifest_consistency::every_dispatch_entry_has_manifest_counterpart` asserts every `NATIVE_MODULE_TABLE` row has an `API_MANIFEST` counterpart. The PR added the `net::read` dispatch row without one, so the check reported `net::read (has_receiver=true, class_filter=-)` missing. Added `method("net", "read", true, Some("Socket"))` next to the other `net.Socket` instance methods, and regenerated `docs/src/api/reference.md`, which the `api-docs-drift` job would otherwise have caught next (one new line plus the entry count; `docs/api/perry.d.ts` is unchanged, since instance methods are not module exports). Re-ported onto the post-train-266 `main`, where #11102 moved perry-stdlib's TLS off `tokio-rustls` onto `perry-tls-session` via `crate::tls_stream::TlsStream`. The split is redone against that tree, not transplanted: `tls_config.rs` names `rustls` directly and owns the `type TlsConnector = Arc<rustls::ClientConfig>` alias `build_tls_connector` now returns; `socket_task.rs` handshakes with `TlsStream::connect(tcp, connector, server_name)` and reads the negotiated session through `stream.session()` instead of `get_ref().1`; `tls_verifier.rs` takes `rustls::client::danger::*` rather than the `tokio_rustls` re-export. Verified as a pure move of main's content: the four files' function sets and their non-import lines are multiset-identical to main's `net/mod.rs` plus this PR's `Socket.read` work.

turnloop P8 group H: deletes the
perry-stdlib → tokio-rustlsmanifest edge (scripts/tokio_inventory.json: 17 → 16 edges, group H 1 → 0).What moves
The three perry-stdlib surfaces that used
tokio_rustlsnow run their handshakes on a sans-I/O rustls session:tls.createServer()acceptcrates/perry-stdlib/src/tls.rsTlsAcceptor::acceptTlsStream::acceptnettls.connect()/upgradeToTLS()crates/perry-stdlib/src/net/mod.rsTlsConnector::connectTlsStream::connectwss://connector (bundled-ws)crates/perry-stdlib/src/ws.rsTlsConnector::connectTlsStream::connectperry_tls_session::TlsSession(new,crates/perry-tls-session/src/session.rs). It handles both client and server over a caller-builtArc<rustls::{Client,Server}Config>, on therustls::unbufferedcore thatturnloop-tlswraps. The existing server config (dynamic SNI cert resolver,addContext, client-cert verifier, ALPN) and the Node CA /rejectUnauthorized:falseclient configs carry over unchanged. This is the accept-side extraction the inventory entry said was missing: until now it existed only inside perry-ext-net (turnloop_tls.rs). perry-ext-net is not touched here, because it is group A's lane. It can switch to this session later.UnbufferedServerConnectionhas noserver_name(). The session reads SNI from the ClientHello as it arrives (session/sni.rs) and normalises it the way rustls does. It only observes the ClientHello; rustls still parses and validates it.received fatal alert: …and not a bare EOF, the same as withtokio_rustls.turnloop_tls::ServerConfig::accept. In the pinned alpha.6 it only takes a single cert with no client auth, which can't expressnode:tls.from_rustlsarrives in alpha.7. Using the rustls unbuffered connection directly follows what perry-ext-net's server session already does, and needs no turnloop bump. The PR does not stack on deps(turnloop): bump the turnloop family to 0.1.0-alpha.8 #11083.crates/perry-stdlib/src/tls_stream.rsdrives the session over the tokio sockets these surfaces already own.

netTLS client and thewss://connector (bundled-ws) are exercised only by the unit tests. Both call the sameTlsStream::connect. No compiled program reached them: even withPERRY_DISABLE_WELL_KNOWN=1, the codegen emitsjs_ext_tls_connect(perry-ext-net). That is why 56 cases fail to compile in that mode on both arms.test-parity/node-suite/https/**(47 cases) and the https test-filestest_node_https_basic/test_parity_httpswere not run. They need the ext-http pump archive set, and the host was short on disk. Their TLS goes through perry-ext-http, which this PR does not touch. From perry-stdlib they reach only the unchanged preflight.cargo test --workspace, and no macOS/Windows runs.

node:tlsserver, bundlednetclient, and secure WebSocket client now use a different handshake implementation while preserving existing connection behavior, error reporting, and secure connection handling.
