use devFdReadDir(pid) and devFdStat(pid, fd) on KernelInterface for PID-aware operations +- Device layer has DEVICE_DIRS set (/dev/fd, /dev/pts) for pseudo-directories — stat returns directory mode 0o755, readDir returns empty (PID context required for dynamic content) +- ResourceBudgets (maxOutputBytes, maxBridgeCalls, maxTimers, maxChildProcesses) flow: NodeRuntimeOptions → RuntimeDriverOptions → NodeExecutionDriver constructor +- Bridge-side timer budget: inject `_maxTimers` number as global, bridge checks `_timers.size + _intervals.size >= _maxTimers` synchronously — host-side enforcement doesn't work because `_scheduleTimer.apply()` is async (Promise) +- Bridge `_scheduleTimer.apply(undefined, [delay], { result: { promise: true } })` is async — host throws become unhandled Promise rejections, not catchable try/catch +- Console output (logRef/errorRef) should NOT count against maxBridgeCalls — output has its own maxOutputBytes budget; counting it would exhaust the budget during error reporting +- Per-execution budget state: `budgetState` object reset via `resetBudgetState()` before each context creation (executeInternal and __unsafeCreateContext) +- Kernel maxProcesses: check `processTable.runningCount() >= maxProcesses` in spawnInternal before PID allocation; throws EAGAIN +- ERR_RESOURCE_BUDGET_EXCEEDED is the error code for all bridge resource budget violations +- maxBuffer enforcement: host-side for sync paths (spawnSyncRef tracks bytes, kills, returns maxBufferExceeded flag), bridge-side for async paths (exec/execFile track bytes, kill child);

createNodeDriver({ useDefaultNetwork: true }) without permissions → fetch EACCES (deny-by-default) + - test-suite context (node.test.ts) always creates with allowAllNetwork — can't test network denial there; use runtime-driver tests instead +--- + +## 2026-03-17 - US-068 +- Implemented sandbox escape security tests proving known escape techniques are blocked +- Files changed: + - packages/secure-exec/tests/runtime-driver/node/sandbox-escape.test.ts (new) +- Tests verify: + - process.binding() returns inert stubs (empty objects), not real native bindings + - process.dlopen() throws "not supported" inside sandbox + - constructor.constructor('return this')() returns sandbox global, not host global + - Object.prototype.__proto__ manipulation stays isolated (setPrototypeOf on Object.prototype throws, no cross-execution proto leakage) + - require('v8').runInDebugContext is undefined (v8 module is an empty stub) + - Combined stress test: Function constructor, eval, indirect eval, vm.runInThisContext, and arguments.callee.caller all fail to escape +- **Learnings for future iterations:** + - process.binding() returns stub objects for common bindings (fs, buffer, etc.) but stubs are empty — no real native methods + - v8 module is an empty object via _moduleCache?.v8 || {} in ESM wrapper + - vm.runInThisContext('this') returns a context reference that differs from globalThis but is still within the sandbox (no host bindings available) + - When testing optional-chain calls like g?.process?.dlopen?.(), be careful: if dlopen is undefined, the call returns undefined without throwing — test for function existence separately from call behavior + - Object.setPrototypeOf(Object.prototype, ...) throws in the sandbox (immutable prototype exotic object) +--- + +## 2026-03-17 - US-069 +- What was implemented: Added global freeze verification and path traversal security tests +- Files changed: + - packages/secure-exec/tests/runtime-driver/node/sandbox-escape.test.ts — added 3 new tests: path traversal with ../../../etc/passwd (EACCES), /proc/self/environ (EACCES), null bytes in path (rejected) + - scripts/ralph/prd.json — marked US-069 as passes: true +- **Learnings for future iterations:** + - Criteria 1-2 (global freeze iteration + non-configurable check) were already covered by existing test "hardens all custom globals as non-writable and non-configurable" in index.test.ts which iterates over ALL HARDENED_NODE_CUSTOM_GLOBALS + - Default createTestNodeRuntime() has no fs permissions (deny-by-default) → all fs reads return EACCES, which is the correct security behavior for path traversal tests + - sandbox-escape.test.ts is the right place for security boundary tests (path traversal, null bytes, escape techniques) +--- + +## 2026-03-17 - US-070 +- Added env variable leakage tests for Node runtime +- Files changed: + - packages/secure-exec/tests/runtime-driver/node/env-leakage.test.ts (new) + - scripts/ralph/prd.json — marked US-070 as passes: true +- **Learnings for future iterations:** + - ExecResult has no stdout field — must use onStdio hook to capture console output, following createConsoleCapture() pattern used across other node runtime-driver tests + - createTestNodeRuntime() from test-utils.ts accepts permissions and processConfig directly — simpler than manually constructing NodeRuntime + createNodeDriver + - Without env permissions (default), filterEnv returns {} — process.env inside sandbox is empty; with allowAllEnv + processConfig.env, all passed vars are accessible + - Exec env override merges with (filtered) initial env — to test "only specified vars", create runtime without processConfig.env +--- + +## 2026-03-17 - US-071 +- What was implemented: Added enforcement tests for memoryLimit (V8 heap) and cpuTimeLimitMs (execution timeout) +- Files changed: + - packages/secure-exec/tests/runtime-driver/node/resource-limits.test.ts (new) + - scripts/ralph/prd.json — marked US-071 as passes: true +- **Learnings for future iterations:** + - memoryLimit is enforced by isolated-vm's V8 heap limit — set to 32MB and allocate 1MB chunks to trigger OOM (non-zero exit code) + - cpuTimeLimitMs produces exit code 124 and errorMessage matching /time limit/i — matches GNU timeout convention + - Tests are fast (~286ms total) — the V8 isolate enforces limits efficiently without needing large tolerances + - createTestNodeRuntime() accepts memoryLimit and cpuTimeLimitMs directly via the spread into nodeProcessOptions +--- + +## 2026-03-17 - US-075 +- Added pipe partial read tests: read 10 of 100 bytes, verify correct first 10 returned and remaining 90 available; multiple 10-byte incremental reads drain 50 bytes exactly +- Added VFS snapshot tests: snapshot() captures files/dirs/symlinks, fromSnapshot() restores correctly with permissions, applySnapshot() replaces in-place, round-trip preserves symlinks +- Also marked US-072, US-073, US-074 as passes: true (already implemented in prior commits but PRD wasn't updated) +- Files changed: + - packages/kernel/test/pipe-manager.test.ts — added 2 partial read tests + - packages/runtime/wasmvm/test/vfs.test.ts — added 7 snapshot tests + - scripts/ralph/prd.json — marked US-072, US-073, US-074, US-075 as passes: true +- **Learnings for future iterations:** + - PipeManager.read(descId, length) returns exactly `length` bytes when available, preserving remainder via chunk.subarray() — drainBuffer handles partial chunk splitting + - VFS.applySnapshot() is a replace, not a merge — it resets all inodes and re-initializes default layout before applying entries + - VFS.snapshot() omits device nodes (e.g., /dev/null) since the VFS constructor recreates them + - Prior iteration commits updated root-level prd.json but the active PRD is at scripts/ralph/prd.json — always update the correct file +--- + +## 2026-03-17 - US-077 +- Added 5 process cleanup and timer disposal tests to dispose-behavior.test.ts +- Files changed: + - packages/secure-exec/tests/kernel/dispose-behavior.test.ts — added 5 new tests + - scripts/ralph/prd.json — marked US-076, US-077 as passes: true +- **Tests added:** + - Crashed process has worker/isolate cleaned up (verifies _activeDrivers map is empty after error exit) + - setInterval does not keep process alive after runtime dispose (verifies dispose completes within 5s) + - Piped stdout/stderr FDs closed on process exit, readers get EOF + - Double-dispose on NodeRuntime does not throw + - Double-dispose on PythonRuntime does not throw (skipped if pyodide unavailable) +- **Learnings for future iterations:** + - NodeRuntimeDriver._activeDrivers.delete(ctx.pid) is called in both success and catch paths of _executeAsync — no leaked entries after crash + - PythonRuntime has explicit `_disposed` flag for idempotent dispose; NodeRuntimeDriver doesn't need one since it just iterates/clears a map + - Kernel.dispose() has its own `disposed` flag, so double-dispose on kernel only calls driver.dispose() once — to test driver-level double-dispose, call driver.dispose() directly after kernel.dispose() +--- + +## 2026-03-17 - US-078 +- Added 8 new tests to device-layer.test.ts covering device behavior gaps +- Tests added: urandom consecutive read uniqueness, /dev/zero write discard, stdin/stdout/stderr stat and read-through, rename EPERM (both source and target), link EPERM, truncate /dev/null no-op +- Files changed: packages/kernel/test/device-layer.test.ts +- **Learnings for future iterations:** + - Device layer writeFile only intercepts /dev/null (discards); all other device paths (including /dev/stdout) pass through to backing VFS + - Device layer readFile only intercepts /dev/null, /dev/zero, /dev/urandom; stdio device reads fall through to backing VFS (ENOENT if not present) + - TestFileSystem.writeFile auto-creates parent directories, so writing to paths like /dev/stdout won't throw in tests — it succeeds in the backing FS + - rename() checks both oldPath and newPath for device paths, so test both directions +--- + +## 2026-03-17 - US-079 +- Added 5 new permission tests to kernel-integration.test.ts "permission deny scenarios" block +- Modified checkPermission() to pass denial reason through to error factory +- Updated fsError() to include optional reason in EACCES message +- Updated checkChildProcess() to include reason in EACCES message +- Tests: writeFile/createDir/removeFile denied when fs checker missing, custom checker reason in error, cwd parameter in childProcess request +- Files changed: packages/kernel/src/permissions.ts, packages/kernel/test/kernel-integration.test.ts +- **Learnings for future iterations:** + - Kernel interface only exposes writeFile/mkdir/readFile/readdir/stat/exists — no createDir or removeFile; test those via wrapFileSystem directly + - wrapFileSystem is exported from permissions.ts and can be imported in tests for direct VFS permission wrapper testing + - checkChildProcess has different deny-by-default: no checker = allow (not deny), unlike fs where no checker = deny + - PermissionDecision.reason was defined in types but never wired through to errors before this change +--- + +## 2026-03-17 - US-080 +- What was implemented: Added @xterm/headless devDependency to @secure-exec/kernel and created TerminalHarness utility +- Files changed: + - packages/kernel/package.json — added @xterm/headless devDependency + - packages/kernel/test/terminal-harness.ts — NEW: TerminalHarness class wiring openShell() to headless xterm Terminal + - pnpm-lock.yaml — updated for new dependency +- **TerminalHarness API:** + - constructor(kernel, options?) — creates 80x24 headless Terminal, opens shell, wires onData → term.write + - type(input) — sends input through PTY, resolves after 50ms settlement (rejects if called re-entrantly) + - screenshotTrimmed() — viewport rows, trimmed per line, trailing empty lines dropped + - line(row) — single trimmed row (0-indexed from viewport top) + - waitFor(text, occurrence?, timeoutMs?) — polls every 20ms, throws with screen dump on timeout or shell death + - exit() — sends ^D and awaits shell exit + - dispose() — kills shell, disposes terminal, idempotent +- **Learnings for future iterations:** + - xterm.write(data, callback) requires callback for buffer to reflect changes synchronously — but settlement-based approach avoids this by waiting for output to stop + - IBuffer.getLine(viewportY + row) gives viewport-relative rows; .translateToString(true) trims trailing whitespace + - @xterm/headless is pure JS, no native addons or DOM — works in vitest/Node.js without any polyfills + - Shell output arrives via shell.onData callback as Uint8Array — term.write accepts both string and Uint8Array +--- + +## 2026-03-17 - US-081 +- Implemented kernel PTY terminal tests with MockShellDriver and TerminalHarness +- Created `packages/kernel/test/shell-terminal.test.ts` with 4 tests: + - clean initial state — screen shows prompt `$ ` + - echo on input — typed text appears via PTY echo + - command output on correct line — output below input line + - output preservation — multiple commands all visible +- Fixed PTY newline echo: `\n` → `\r\n` in `packages/kernel/src/pty.ts` (line discipline must echo CR+LF for correct terminal cursor positioning) +- Updated existing echo test assertion in `kernel-integration.test.ts` for `\r\n` +- Files changed: `packages/kernel/src/pty.ts`, `packages/kernel/test/shell-terminal.test.ts` (new), `packages/kernel/test/kernel-integration.test.ts` +- **Learnings for future iterations:** + - PTY line discipline must echo newline as `\r\n` (CR+LF), not bare `\n` — xterm.js treats LF as cursor-down only, not CR+LF; without CR the cursor stays at current column + - `translateToString(true)` preserves explicitly-written space characters (e.g., `$ ` → `$ `, not `$`) — xterm distinguishes written cells from default/empty cells + - Mock shell for terminal tests should use kernel FDs (`ki.fdRead`/`ki.fdWrite`) with PTY slave, not DriverProcess callbacks — PTY I/O goes through kernel FD table + - Shell output must use `\r\n` for line breaks since the kernel has no ONLCR output processing — programs are responsible for CR+LF in their PTY output + - MockShellDriver pattern: async REPL loop reading from stdin FD, dispatching simple commands, writing prompt — reusable for US-082 signal/backspace tests +--- + +## 2026-03-17 - US-082 +- Added 6 kernel PTY terminal tests: ^C/SIGINT, ^D/exit, backspace, line wrapping, SIGWINCH/resize, echo disabled +- Enhanced MockShellDriver: SIGINT writes "^C\r\n$ " and continues, SIGWINCH ignored, added "noecho" command for echo disable +- Files changed: `packages/kernel/test/shell-terminal.test.ts` +- **Learnings for future iterations:** + - PTY signal chars (^C) are NOT echoed by the line discipline — the mock shell's kill() handler writes "^C\r\n$ " to simulate real shell behavior + - `processTable.kill(-pgid, signal)` calls `driverProcess.kill(signal)` — driver decides whether to exit or survive (bash ignores SIGINT, continues with new prompt) + - For line wrapping tests, use small terminal cols (e.g., 20) — prompt "$ " takes 2 chars, remaining cols determine wrap point + - Echo disabled via `ki.ptySetDiscipline(pid, fd, { echo: false })` — canonical mode still buffers input, just doesn't echo; output from shell (fdWrite to slave) still appears + - `harness.term.resize()` changes xterm viewport; `harness.shell.resize()` delivers SIGWINCH via kernel — both needed for resize tests +--- + +## 2026-03-17 - US-083 +- Added WasmVM terminal tests using @xterm/headless for screen-state verification +- Fixed WasmVM driver PTY routing: stdout/stderr now routes through kernel fdWrite for PTYs (not just pipes) +- Added ONLCR output processing to PTY slave write path (converts \n to \r\n, POSIX standard) +- Added ttyFds passthrough so brush-shell detects interactive mode and shows prompt +- Implemented getIno/getInodeByIno in kernel VFS adapter for WASI path_filestat_get support +- Tests passing: echo, output preservation, export (exact screen-state matching) +- Tests .todo: ls (proc_spawn child PID retrieval fails), cd (hangs on WASI path resolution when dir exists) +- Files changed: + - `packages/kernel/src/pty.ts` — ONLCR output processing + - `packages/kernel/test/kernel-integration.test.ts` — updated slave→master test for ONLCR + - `packages/runtime/wasmvm/src/driver.ts` — _isFdKernelRouted (detects PTY + pipe), stdinIsPty bypass, ttyFds detection + - `packages/runtime/wasmvm/src/kernel-worker.ts` — ttyFds in UserManager, getIno/getInodeByIno via vfsStat RPC + - `packages/runtime/wasmvm/src/syscall-rpc.ts` — ttyFds field in WorkerInitData + - `packages/runtime/wasmvm/test/shell-terminal.test.ts` — new test file + - `packages/runtime/wasmvm/test/terminal-harness.ts` — TerminalHarness (duplicated from kernel) + - `packages/runtime/wasmvm/package.json` — @xterm/headless devDep +- **Learnings for future iterations:** + - WasmVM driver must check isatty() (not just pipe filetype) to detect PTY-connected FDs — default character device and PTY slave share filetype 2 + - Driver must NOT create stdin pipe when FD 0 is already a PTY slave (breaks interactive input flow) + - brush-shell prompt format is "sh-0.4$ " — capture as constant at top of test file + - ONLCR (LF→CRLF) is required on PTY slave output for correct terminal rendering — xterm.js LF alone only moves cursor down, not to column 0 + - brush-shell's cd builtin hangs when target dir exists — likely blocks on WASI path_open or fd_readdir after path_filestat_get succeeds + - ls from interactive shell shows "WARN could not retrieve pid for child process" — proc_spawn return value not read correctly by brush-shell + - kernel VFS adapter getIno must parse the vfsStat RPC response's "type" field (not "isDirectory") since the handler encodes type as string +--- + +## 2026-03-18 - US-122 +- What was implemented: Added EPIPE check for pipe write when read end is closed +- Files changed: + - `packages/kernel/src/pipe-manager.ts` — added `state.closed.read` check in write() before buffering + - `packages/kernel/test/pipe-manager.test.ts` — added two tests: write-after-read-close throws EPIPE, write-with-open-read succeeds +- **Learnings for future iterations:** + - PipeManager write() already checked write-end closure but not read-end — POSIX requires EPIPE when no readers exist + - The check order matters: EBADF → EPIPE (write closed) → EPIPE (read closed) → deliver/buffer +--- + +## 2026-03-18 - US-124 +- What was implemented: Clean up child processes and HTTP servers on isolate disposal/timeout + - Added `activeChildProcesses: Map` to DriverDeps for host-level child process tracking + - Added `killActiveChildProcesses()` utility that SIGKILL's all tracked processes + - Changed bridge-setup.ts to use `deps.activeChildProcesses` instead of local `sessions` map (promotes tracking from context-local to driver-level) + - Removed `activeHttpServerIds.clear()` from execution.ts exec() start — servers from previous exec are now tracked across calls + - Removed `activeHttpServerIds` from ExecutionRuntime type (no longer needed in execution.ts) + - Added `closeActiveHttpServers()` to execution-driver.ts for sync fire-and-forget server cleanup + - recycleIsolate(): now calls killActiveChildProcesses + closeActiveHttpServers before disposing + - dispose(): now calls killActiveChildProcesses + closeActiveHttpServers before disposing + - terminate(): now calls killActiveChildProcesses before awaiting server close +- Files changed: + - packages/secure-exec-node/src/isolate-bootstrap.ts — added activeChildProcesses to DriverDeps, added killActiveChildProcesses() + - packages/secure-exec-node/src/bridge-setup.ts — added activeChildProcesses to BridgeDeps, replaced local sessions map + - packages/secure-exec-node/src/execution.ts — removed activeHttpServerIds.clear() and from ExecutionRuntime type + - packages/secure-exec-node/src/execution-driver.ts — added cleanup to recycleIsolate/dispose/terminate, added closeActiveHttpServers() + - packages/secure-exec/tests/runtime-driver/node/resource-budgets.test.ts — added child process cleanup and HTTP server cleanup tests +- **Learnings for future iterations:** + - Bridge's local `sessions` Map was context-scoped — each setupRequire() call created a new one, orphaning processes from previous contexts. Moving to DriverDeps fixes this. + - `activeHttpServerIds.clear()` in exec() start was silently losing server tracking — servers created in exec N were invisible to cleanup after exec N+1 started + - recycleIsolate is called on CPU timeout — any resource cleanup that should happen on timeout must be added there, not just in terminate() + - closeActiveHttpServers uses fire-and-forget (no await) since the isolate is being disposed — awaiting could block disposal + - Tests for timeout-triggered cleanup: create resource, then `while (true) {}` to trigger CPU timeout, verify cleanup happened +--- + +## 2026-03-18 - US-125 +- Verified all fixes already implemented in prior iterations: + - logRef/errorRef check `budgetState.outputBytes + bytes > maxOutputBytes` (not `>=` on previous total) + - spawnSync defaults to `options.maxBuffer ?? 1024 * 1024` (1MB) + - exec() bridge-side has `if (maxBufferExceeded) return;` guard in both stdout/stderr data handlers +- Tests already exist and pass: + - resource-budgets.test.ts: maxOutputBytes budget rejection of single large message (1MB vs 1024 budget), stderr budget, default spawnSync maxBuffer + - maxbuffer.test.ts: execSync/spawnSync/execFileSync maxBuffer enforcement +- All 25 tests pass, typecheck passes +- Files verified (no changes needed): + -

US-126, US-127, US-123, US-128, US-129, US-130, US-131 +- Batch-verified 7 stories already implemented in prior iterations with passing tests +- Updated PRD to mark all as passes: true +- **Learnings for future iterations:** + - Multiple stories were implemented but PRD wasn't updated — batch-verify before starting new work +--- + +## 2026-03-18 - US-132 +- Added module cache clearing to `__unsafeCreateContext` in execution-driver.ts — clears all 10 caches (esmModuleCache, esmModuleReverseCache, dynamicImportCache, dynamicImportPending, 4 resolutionCache maps, moduleFormatCache, packageTypeCache) +- Added test verifying module cache isolation: first context requires module v1, VFS updated to v2, second context correctly sees v2 +- Files changed: + - packages/secure-exec-node/src/execution-driver.ts — added cache clearing to `__unsafeCreateContext` + - packages/secure-exec/tests/runtime-driver/node/bridge-hardening.test.ts — added module cache isolation test +- **Learnings for future iterations:** + - `__unsafeCreateContext` requires absolute paths for require() — relative paths fail because filename is synthetic + - Module caches on `deps` must be cleared in BOTH `executeWithRuntime` and `__unsafeCreateContext` +--- + +## 2026-03-18 - US-134 +- Added `pread(path, offset, length)` method to kernel VirtualFileSystem interface for range-based reads +- Updated fdRead in kernel.ts to use pread instead of readFile+slice — avoids loading entire file for partial reads +- Implemented pread in all kernel VFS implementations: TestFileSystem, NodeFileSystem (os/node), InMemoryFileSystem (os/browser) +- Updated device-layer.ts to handle pread for device nodes (/dev/null, /dev/zero, /dev/urandom) +- Updated permissions.ts to wrap pread with "read" permission check +- Added 2 tests: 1MB file single-byte read, sequential cursor advancement +- Files changed: + - packages/kernel/src/vfs.ts — added pread to interface + - packages/kernel/src/kernel.ts — fdRead now uses pread + - packages/kernel/src/device-layer.ts — pread wrapper for device nodes + - packages/kernel/src/permissions.ts — pread permission check + - packages/kernel/test/helpers.ts — TestFileSystem.pread + - packages/os/node/src/filesystem.ts — NodeFileSystem.pread (uses fs.open + handle.read for true partial read) + - packages/os/browser/src/filesystem.ts — InMemoryFileSystem.pread + - packages/kernel/test/kernel-integration.test.ts — 2 new tests +- **Learnings for future iterations:** + - Kernel VFS (packages/kernel/src/vfs.ts) is separate from core VFS (packages/secure-exec-core/src/types.ts) — only kernel VFS implementations need updating for kernel-only methods + - Only 3 classes implement kernel VFS: TestFileSystem (kernel tests), NodeFileSystem (os/node), InMemoryFileSystem (os/browser) + - NodeFileSystem.pread uses fs.open() + handle.read(buf, 0, length, offset) for true OS-level positional read + - device-layer pread for /dev/zero returns exactly `length` zero bytes (unlike readFile which returns fixed 4096) +--- + +## 2026-03-18 - US-133 +- Already implemented in prior iteration: setpgid cross-session EPERM check (process-table.ts:184-186) and terminateAll SIGKILL escalation (process-table.ts:288-306) +- Tests already exist: kernel-integration.test.ts lines 934-954 (terminateAll SIGKILL) and 2196-2235 (setpgid cross-session) +- Marked passes: true in prd.json +- **Learnings for future iterations:** + -

packages/kernel/src/pty.ts — echoOutput throws EAGAIN instead of silent drop + - packages/kernel/test/resource-exhaustion.test.ts — new echo buffer overflow test +- **Learnings for future iterations:** + - echoOutput is called from processInput (master write path) — EAGAIN propagates to the caller who can drain and retry + - deliverInput already throws EAGAIN for full input buffer; now echo is consistent +--- + +## 2026-03-18 -

None new — patterns already documented +--- + +## 2026-03-18 - US-107 +- Implemented PGID validation in tcsetpgrp — throws ESRCH for non-existent process groups +- Added `hasProcessGroup(pgid)` method to ProcessTable that checks for running processes with matching pgid +- Added validation check in kernel.ts tcsetpgrp handler before delegating to ptyManager +- Added two new tests: non-existent pgid throws ESRCH, valid pgid succeeds +- Files changed: packages/kernel/src/process-table.ts, packages/kernel/src/kernel.ts, packages/kernel/test/kernel-integration.test.ts +- **Learnings for future iterations:** + - ProcessTable already has pgid loop patterns in setpgid() and kill() — hasProcessGroup follows same pattern (iterate entries, check pgid + status) + - Validation belongs in kernel.ts (not pty.ts) since process groups are kernel-level concepts; PtyManager shouldn't need to know about ProcessTable + - All 158 kernel integration tests pass, including all existing tcsetpgrp tests +--- + +## 2026-03-18 - US-108 +- Added adversarial PTY stress tests to packages/kernel/test/resource-exhaustion.test.ts +- 7 new tests in "PTY adversarial stress" describe block: + - Rapid sequential master writes (100+ chunks, 1KB each) with no slave reader — verifies EAGAIN and bounded memory + - Single large master write (1MB) — verifies immediate EAGAIN, no partial buffering + - Single large slave write (1MB) — same for output direction + - Multiple PTY pairs (5) simultaneously filled — verifies isolation (drain one, others stay full) + - Canonical mode line buffer under sustained input without newline — verifies MAX_CANON cap + - Canonical mode with echo — verifies echo output stays bounded under sustained input + - Rapid sequential slave writes (100+ chunks) with no master reader — verifies EAGAIN and bounded memory +- Files changed: packages/kernel/test/resource-exhaustion.test.ts +- **Learnings for future iterations:** + - PtyManager.close() removes descToPty entries immediately — async drain loops must catch EBADF after close + - In canonical mode, chars beyond MAX_CANON are silently dropped (no EAGAIN) — only buffer-level EAGAIN applies to input/output buffers + - Echo with canonical mode: echo output is bounded by MAX_CANON (only accepted chars get echoed) + 2 bytes for CR+LF on newline flush +--- + +## 2026-03-18 - US-109, US-110 +- US-109: Already implemented in prior iteration (commit 667669d). Verified tests pass, marked passes: true. +- US-110: Added 2 kernel-integration-level PTY echo buffer exhaustion tests through fdWrite/fdRead kernel interface + - Test 1: fill output buffer via slave write, verify fdWrite to master with echo enabled throws EAGAIN + - Test 2: drain buffer via master read, verify echo resumes (write 'B', read echo 'B' back) +- Files changed: packages/kernel/test/kernel-integration.test.ts (added MAX_PTY_BUFFER_BYTES import + 2 tests in termios section) +- **Learnings for future iterations:** + - Integration-level PTY tests use ki.fdWrite/ki.fdRead (kernel interface), not ptyManager.write/read directly + - Output buffer fills via slave write (slave→master direction);

bridge-handlers.ts handler args use `unknown` type (coerce with String()/Number()/Buffer.from()), whereas bridge-setup.ts uses typed args because ivm.Reference enforces types + - The 4 cipheriv test failures in crypto.ts are pre-existing and relate to US-003 scope +--- + +## 2026-03-20 19:05 -

pbkdf2/scrypt handler implementations are straightforward ports from bridge-setup.ts ivm.Reference wrappers — just remove ivm wrapping and use `unknown` args + - All 7 pbkdf2/scrypt tests pass (pbkdf2Sync, pbkdf2 async, pbkdf2Sync with Buffer args, scryptSync, scryptSync default options, scrypt async, scrypt async without options) + - The scrypt handler passes optionsJson as a string that gets JSON.parsed on host side — guest-side require-setup.ts handles option normalization (cost→N, blockSize→r, parallelization→p) +--- + +## 2026-03-20 19:25 - US-003 +- Added handlers[K.cryptoCipheriv] — takes algorithm, keyBase64, ivBase64, dataBase64; returns JSON with data (+ authTag for GCM) +- Added handlers[K.cryptoDecipheriv] — takes algorithm, keyBase64, ivBase64, dataBase64, optionsJson; returns decrypted data as base64 +- Bridge contract keys already present — no changes needed +- Also fixed 4 pre-existing cipheriv test failures by running `pnpm turbo build --force` to rebuild stale dist +- Files changed: packages/secure-exec-node/src/bridge-handlers.ts +- All 63 node test suite tests pass (including all 4 cipheriv tests: AES-256-CBC, AES-128-CBC, AES-256-GCM, AES-128-GCM) +- **Learnings for future iterations:** + - The @secure-exec/core dist/generated/isolate-runtime.js can become stale if built from a different branch; the tests import via dist (package.json exports map) not src + - If crypto tests fail with "bad decrypt" or "Invalid key", the dist is stale — rebuild with `pnpm turbo build --force` + - Cipheriv handler returns JSON.stringify({ data, authTag? }) — the guest-side SandboxCipher in require-setup.ts parses this JSON to extract encrypted data and auth tag + - GCM modes require authTag handling: cipher returns it, decipher receives it via optionsJson + - The `as any` cast on createCipheriv/createDecipheriv return is needed because getAuthTag() is only available on GCM ciphers +--- + +## 2026-03-20 19:35 - US-004 +- Added handlers[K.cryptoCipherivCreate] — creates cipher/decipher session on host, stores in Map, returns sessionId +- Added handlers[K.cryptoCipherivUpdate] — feeds data into open session, returns partial encrypted/decrypted data as base64 +- Added handlers[K.cryptoCipherivFinal] — finalizes session, returns last block + authTag for GCM, removes session from map +- Added bridge contract keys: cryptoCipherivCreate, cryptoCipherivUpdate, cryptoCipherivFinal +- Changed buildCryptoBridgeHandlers() return type from BridgeHandlers to CryptoBridgeResult { handlers, dispose } +- Added type refs: CryptoCipherivCreateBridgeRef, CryptoCipherivUpdateBridgeRef, CryptoCipherivFinalBridgeRef +- Files changed: packages/secure-exec-core/src/shared/bridge-contract.ts, packages/secure-exec-node/src/bridge-handlers.ts +- All 63 node test suite tests pass, typecheck passes +- **Learnings for future iterations:** + - The stateful session pattern (Map + nextId counter) mirrors child_process sessions in bridge-setup.ts + - Create handler takes a `mode` arg ("cipher" | "decipher") so one handler covers both directions + - For GCM, authTag must be set on the decipher at create time (not update/final) — this differs from the one-shot approach where authTag is passed via optionsJson to decipheriv + - Final handler returns JSON for both GCM and non-GCM — keeps the interface uniform; guest-side parses JSON to extract data and optional authTag + -

The sign handler passes `String(algorithm) || null` — the `|| null` is needed because Ed25519 keys use null algorithm (the algorithm is implicit in the key type) + - The verify handler uses createPublicKey() while sign uses createPrivateKey() — this matches Node.js crypto API expectations (sign with private, verify with public) + - generateKeyPairSync always forces PEM output (spki/pkcs8) regardless of guest-requested encoding — PEM is the cross-boundary transfer format; guest-side require-setup.ts re-wraps as KeyObject if needed + - Bridge contract key type refs (CryptoSignBridgeRef, CryptoVerifyBridgeRef, CryptoGenerateKeyPairSyncBridgeRef) already existed — these are used by the guest-side bridge type declarations +--- + +## 2026-03-20 19:45 - US-006 +- Added handlers[K.cryptoSubtle] to bridge-handlers.ts — full Web Crypto API dispatcher handling: digest, generateKey, importKey, exportKey, encrypt, decrypt, sign, verify, deriveBits, deriveKey +- Added deriveBits support for PBKDF2 (pbkdf2Sync) and HKDF (hkdfSync) algorithms +- Added deriveKey support for PBKDF2 and HKDF algorithms (derives bits then wraps as CryptoKey) +- Added SandboxSubtle.deriveBits and SandboxSubtle.deriveKey methods to guest-side require-setup.ts +- Added matching deriveBits/deriveKey cases to isolated-vm bridge-setup.ts cryptoSubtle dispatcher +- Added 4 new tests: deriveBits PBKDF2, deriveBits PBKDF2 determinism, deriveBits HKDF, deriveKey PBKDF2 with AES-GCM encrypt/decrypt roundtrip +- Bridge contract key for cryptoSubtle already existed — no changes needed +- Files changed: packages/secure-exec-node/src/bridge-handlers.ts, packages/secure-exec-node/src/bridge-setup.ts, packages/secure-exec-core/isolate-runtime/src/inject/require-setup.ts, packages/secure-exec-core/src/generated/isolate-runtime.ts, packages/secure-exec/tests/test-suite/node/crypto.ts +- All 67 node test suite tests pass (63 original + 4 new deriveBits/deriveKey tests) +- **Learnings for future iterations:** + - The cryptoSubtle handler is a single dispatcher for ALL Web Crypto operations — when porting from isolated-vm, port all operations (not just new ones) so the V8 handler is complete + - Guest-side SandboxSubtle in require-setup.ts serializes salt/info/iv as base64 via toBase64() helper; the host side decodes them back with Buffer.from(x, 'base64') + - normalizeHash() strips hyphens and lowercases: 'SHA-256' → 'sha256' — needed because Node.js crypto uses 'sha256' while Web Crypto uses 'SHA-256' + - hkdfSync from node:crypto returns ArrayBuffer, must wrap with Buffer.from() to call .toString('base64') + - SandboxCryptoKey wraps key data in a _keyData property — the bridge receives this property, not the CryptoKey directly + - When adding operations to bridge-setup.ts (isolated-vm), must also add hkdfSync to the crypto import +--- + +## 2026-03-20 19:52 - US-007 +- Added buildNetworkSocketBridgeHandlers() to bridge-handlers.ts with handlers for net socket connect, write, end, destroy +- Added bridge contract keys: netSocketConnectRaw, netSocketWriteRaw, netSocketEndRaw, netSocketDestroyRaw to HOST_BRIDGE_GLOBAL_KEYS +- Added netSocketDispatch to RUNTIME_BRIDGE_GLOBAL_KEYS for host→guest event dispatch +- Added type refs: NetSocketConnectRawBridgeRef, NetSocketWriteRawBridgeRef, NetSocketEndRawBridgeRef, NetSocketDestroyRawBridgeRef +- Added netSocketConnect, netSocketWrite, netSocketEnd, netSocketDestroy optional methods to NetworkAdapter interface +- Added "connect" op to NetworkAccessRequest for net socket permission checks +- Added permission-wrapped net socket forwarding in wrapNetworkAdapter() +- Added net socket implementation in createDefaultNetworkAdapter() (driver.ts) with socket Map tracking +- Files changed: packages/secure-exec-core/src/shared/bridge-contract.ts, packages/secure-exec-core/src/types.ts, packages/secure-exec-core/src/shared/permissions.ts, packages/secure-exec-node/src/bridge-handlers.ts, packages/secure-exec-node/src/driver.ts +- All 67 node test suite tests pass, 116 runtime-driver tests pass, 16 permissions tests pass, typecheck passes +- **Learnings for future iterations:** + - Net socket handlers follow the same stateful session pattern as cipher sessions (Map + nextId counter) but with a dispatch callback for host→guest event push + - buildNetworkSocketBridgeHandlers() takes a NetSocketBridgeDeps with a dispatch function — this function needs to be wired by the V8 runtime driver (US-012) to call _netSocketDispatch on the guest side + - The dispatch pattern mirrors childProcessDispatch: a single function routes events by socketId + event name (connect, data, end, error, close) + - Socket data is transferred as base64 (same as other binary bridge transfers) + - NetworkAdapter.netSocketConnect() is the full-featured version with callbacks; the bridge handler uses net.connect() directly for simplicity + - The project-matrix test has a pre-existing failure (nextjs-start-pass stderr formatting mismatch) unrelated to net socket changes +--- + +## 2026-03-20 20:01 - US-008 +- Added handlers[K.netSocketUpgradeTlsRaw] to buildNetworkSocketBridgeHandlers() — wraps existing net.Socket with tls.TLSSocket on host; re-wires events (secureConnect, data, end, error, close) via dispatch +- Added buildUpgradeSocketBridgeHandlers() function for HTTP upgrade socket write/end/destroy — delegates to NetworkAdapter +- Added netSocketUpgradeTlsRaw bridge contract key + type ref to bridge-contract.ts +- Added netSocketUpgradeTls method to NetworkAdapter interface in types.ts +- Added netSocketUpgradeTls implementation in createDefaultNetworkAdapter() in driver.ts +- Added permission forwarding for netSocketUpgradeTls in wrapNetworkAdapter() +- Files changed: packages/secure-exec-core/src/shared/bridge-contract.ts, packages/secure-exec-core/src/types.ts, packages/secure-exec-core/src/shared/permissions.ts, packages/secure-exec-node/src/bridge-handlers.ts, packages/secure-exec-node/src/driver.ts +- All 67 node test suite tests pass, all 288 node runtime-driver tests pass, 42/43 project-matrix tests pass (1 pre-existing nextjs failure), typecheck passes +- **Learnings for future iterations:** + - TLS upgrade handler operates on the same socket map as net socket handlers — wraps the existing socket in-place by replacing the map entry, so write/end/destroy continue to work transparently + - socket.removeAllListeners() is critical before wrapping — prevents double event firing from both the raw and TLS socket layers + - The tls.TLSSocket is cast as `unknown as net.Socket` when stored in the map because the map type is Map but TLSSocket extends net.Socket (the cast is safe) + - Upgrade socket handlers (for HTTP WebSocket relay) are separate from net socket TLS upgrade — they delegate to NetworkAdapter while net socket handlers manage their own socket map directly + - rejectUnauthorized defaults to false in the TLS upgrade handler — this matches the isolated-vm behavior and is needed for self-signed certificates in dev environments +--- + +## 2026-03-20 20:12 - US-009 +- Added resolveModuleSync and loadFileSync keys to HOST_BRIDGE_GLOBAL_KEYS in bridge-contract.ts +- Added type refs ResolveModuleSyncBridgeRef and LoadFileSyncBridgeRef +- Added toHostPath() and toSandboxPath() public methods to ModuleAccessFileSystem for sandbox↔host path translation +- Added buildModuleResolutionBridgeHandlers() to bridge-handlers.ts with truly synchronous require.resolve() and readFileSync() handlers +- Modified guest-side require-setup.ts _resolveFrom() and file loading to prefer sync handlers when available (_resolveModuleSync/_loadFileSync) +- Files changed: packages/secure-exec-core/src/shared/bridge-contract.ts, packages/secure-exec-core/isolate-runtime/src/inject/require-setup.ts, packages/secure-exec-core/src/generated/isolate-runtime.ts, packages/secure-exec-node/src/bridge-handlers.ts, packages/secure-exec-node/src/module-access.ts +- All 67 node test suite tests pass, all 288 node runtime-driver tests pass, 42/43 project-matrix tests pass (1 pre-existing nextjs failure), typecheck passes +- **Learnings for future iterations:** + - The sync handlers bypass the VirtualFileSystem and use Node.js require.resolve() + readFileSync() directly — this is intentional because the async VFS path can't nest inside synchronous bridge callbacks + - ModuleAccessFileSystem.toHostPath() is the public wrapper around the private overlayHostPathFor() — use it for sandbox→host path translation in bridge handlers + - ModuleAccessFileSystem.toSandboxPath() reverses the translation — converts host paths back to sandbox /root/node_modules/... paths + - buildModuleResolutionBridgeHandlers() takes a deps object with sandboxToHostPath/hostToSandboxPath — these should be wired from ModuleAccessFileSystem when the V8 driver creates handlers (US-012) + - The guest-side require-setup.ts detects sync handlers via `typeof _resolveModuleSync !== 'undefined'` — in isolated-vm mode these globals aren't set, so it falls back to the existing applySyncPromise pattern + - transformDynamicImport() is called in loadFileSync to match the loadFile handler behavior (converts import() to __dynamicImport()) + - createRequire(import.meta.url) is needed in ESM files to get access to require.resolve() +--- + +## 2026-03-20 20:17 -

V8 (via isolated-vm) throws on conflicting star exports whereas Node.js makes them ambiguous/undefined — deconflictStarExports() bridges this gap + - The function uses regex-based static analysis to extract export names from target modules — it doesn't recurse into nested `export *` targets for simplicity + - The approach: keep the first source's `export *` intact, replace later conflicting sources with explicit `export { nonConflicting } from 'specifier'` + - The regex pattern uses `^` anchor with `gm` flags so it only matches `export *` at the start of a line + - The implementation was ported from commit 2cec1d6 on the ralph/cli-tool-sandbox-tests branch (US-029) + - deconflictStarExports uses resolveESMPath + loadFile from existing deps — same resolution as the rest of the ESM compiler +--- + +## 2026-03-20 20:30 -

The global Buffer in the sandbox comes from bridge/process.ts (not require-setup.ts) — patches to Buffer.prototype must be applied there, not just in _patchPolyfill + - Bridge code (network.ts, process.ts) runs inside the sandbox IIFE before require-setup.ts — polyfill gaps in bridge classes need direct fixes, not _patchPolyfill workarounds + - Response.body.getReader() must return an async read() that yields Uint8Array chunks, not strings — this matches the ReadableStream spec that undici and similar packages expect + - The FormData global is conditionally added (only if not already defined) to match the Blob stub pattern + -
