   - The FormData global is conditionally added (only if not already defined) to match the Blob stub pattern
   - runtime.run() with CJS modules does not support top-level await — use .then() callbacks for async results in CJS test code
   - Buffer encoding methods (utf8Slice/utf8Write) are internal V8 bindings not part of the feross/buffer polyfill — must be shimmed as this.toString(enc)/this.write(str,off,len,enc)
+- Do NOT use _registerHandle for net sockets — _waitForActiveHandles() blocks dispatch callbacks; libraries use their own async patterns (Promises, callbacks) which keep execution alive via the script result promise
+- Net socket dispatch from host to guest requires the isolate to be idle (awaiting a promise); _scheduleTimer.applySyncPromise works for keeping alive while allowing dispatch, but _waitForActiveHandles blocks dispatch
+- Sync module resolution handlers (_resolveModuleSync, _loadFileSync) must fall back to async handlers when they return null — critical for InMemoryFileSystem and VirtualFileSystem that don't have toHostPath/toSandboxPath
+- Sync module resolution handlers should only resolve non-builtin modules when hasPathTranslation is true — prevents leaking host filesystem modules (e.g. chalk from workspace node_modules) into the sandbox
+- Streaming cipher sessions (_cryptoCipherivCreate/Update/Final) are more correct than one-shot mode — update() returns real encrypted data; cipher tests must use Buffer.concat([update(), final()]) pattern
+- The ssh2 library needs crypto.diffieHellman() (Node 15+ API, not in browserify polyfill) or a working ECDH key exchange via the browserify createECDH; the KEXINIT message is sent but the server closes the connection, suggesting the KEXINIT algorithm list or binary format is incompatible

+- Ported e2e-docker test runner and all 17 fixtures from main branch
+- Implemented guest-side net module (NetSocket class) in bridge/network.ts with TCP socket support via _netSocketConnectRaw/_netSocketWriteRaw/_netSocketEndRaw/_netSocketDestroyRaw bridge globals
+- Implemented guest-side tls module (tlsConnect) in bridge/network.ts with TLS upgrade via _netSocketUpgradeTlsRaw bridge global
+- Added _netSocketDispatch event dispatch callback for host→guest socket event routing (connect, data, end, error, close, secureConnect)
+- Wired net socket, TLS upgrade, stateful cipher session, and sync module resolution handlers into bridge-setup.ts as ivm.Reference objects
+- Added stateful cipher session handlers (_cryptoCipherivCreate/_cryptoCipherivUpdate/_cryptoCipherivFinal) to bridge-setup.ts
+- Updated SandboxCipher/SandboxDecipher in require-setup.ts to use streaming session mode when handlers available — update() now returns real encrypted data
+- Added sync module resolution fallback: _resolveModuleSync returns null → falls back to async _resolveModule handler
+- Removed net/tls from _deferredCoreModules, added special require() handling for net and tls modules
+- Added _netModule, _tlsModule, _netSocketDispatch to NODE_CUSTOM_GLOBAL_INVENTORY
+- Fixed cipheriv tests to use correct Buffer.concat([update, final]) pattern matching Node.js behavior
+- Files changed: packages/secure-exec-core/src/bridge/network.ts, packages/secure-exec-core/isolate-runtime/src/inject/require-setup.ts, packages/secure-exec-core/src/generated/isolate-runtime.ts, packages/secure-exec-core/src/shared/global-exposure.ts, packages/secure-exec-node/src/bridge-setup.ts, packages/secure-exec/tests/test-suite/node/crypto.ts, packages/secure-exec/tests/utils/docker.ts, packages/secure-exec/tests/e2e-docker.test.ts, packages/secure-exec/tests/e2e-docker/ (17 fixtures)
+- 10/17 e2e-docker fixtures pass: pg-connect, pg-pool, pg-types, pg-errors, pg-prepared, pg-ssl, mysql2-connect, ioredis-connect, ssh2-auth-fail, ssh2-connect-refused
+- 7 SSH fixtures fail: ssh2-connect, ssh2-key-auth, ssh2-tunnel, ssh2-sftp-dirs, ssh2-sftp-large, ssh2-sftp-transfer, ssh2-auth-fail — all timeout during SSH KEXINIT handshake
+- All 79 node test suite tests pass, all 367 runtime-driver+node tests pass, typecheck passes
+- **Learnings for future iterations:**
+  - Net sockets must NOT use _registerHandle — _waitForActiveHandles() creates a deadlock where dispatch callbacks can't execute during the wait. Libraries keep execution alive through their own Promise chains
+  - The _scheduleTimer.applySyncPromise() mechanism allows host→guest applySync dispatch during the wait, but _waitForActiveHandles (via context.eval with promise:true) blocks dispatch
+  - Sync module resolution must check hasPathTranslation before resolving non-builtins — InMemoryFileSystem doesn't have toHostPath, so sync resolution on the host filesystem would leak workspace modules into the sandbox
+  - Streaming cipher sessions (create/update/final) are required for ssh2's packet encryption — the one-shot approach (collect in update, encrypt in final) breaks SSH protocol because update() must return real encrypted data for each packet
+  - ssh2 KEXINIT failure: TCP connects, version exchange works, KEXINIT is sent, but server closes connection — likely the polyfilled crypto.createECDH output format differs from what OpenSSH expects, or the KEXINIT algorithm list encoding is wrong due to Buffer handling in the polyfill
+  - The project-matrix kernel tests (40/42 fail) are pre-existing failures unrelated to this change
