feat(cli): headless CLI for create/compile/upload/debug (DOPE-567) - #1026
Conversation
…he store `getCompileReadyProjectData` held the only implementation of the rules that turn a variable's `location` into the address the compiler emits. Living in a Zustand action made it unreachable from anything without a store — notably the headless CLI (DOPE-567), which would have had to reimplement it and would then have drifted from the GUI, so a project compiled from the terminal could resolve differently from the same project compiled from the editor. Move the rules to `resolveProjectAliases`, a pure function beside the registry they depend on, and reduce the store action to pairing live project data with the memoized alias index. Behaviour is unchanged: the same two collections are walked (POU interface variables and resource globals), and GVLs stay outside the alias surface, matching `renameAlias`. Byte-identical with openplc-web. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…dless CLI Foundation for DOPE-567, built in the order the ticket calls for: the session mechanism first, so the REPL can be a client of it rather than a second implementation. - `exit-codes.ts`: distinct exit codes plus stable `ErrorCode` strings, so a test branches on a code instead of matching on prose that is free to change. - `output.ts`: mode chosen from `isatty` rather than a flag — a harness that forgot `--json` still gets JSON. In JSON mode stdout carries exactly one document and progress goes to stderr, so callers can `JSON.parse(stdout)` without filtering. - `session/protocol.ts`: NDJSON request/response with correlation ids, so response completion is explicit instead of inferred from prompt matching. `CloseRequest.releaseForces` defaults to true because forcing lives in the runtime's forced-slot bitmap and the runtime cannot notice a debugger going away — it only clears on program unload/stop, so a session that exits quietly would strand pinned outputs on a live PLC. - `session/registry.ts`: `session_id` → socket mapping with liveness checked on every read. A record outliving its process is the common case (SIGKILL, suspend, CI teardown), and reporting a dead session is worse than omitting it, because an operator reads the list to find forces to clear. - `args.ts`: declared boolean flags never consume the following token. 46 tests, no hardware required.

Adds `openplc` — devices / compile / upload / debug — running as an Electron main process with no window. Not a plain Node process, because `CompilerModule` and ten other modules under `backend/editor` resolve arduino-cli, the strucpp includes, the licence store and installed VPP packages through Electron's `app` paths; de-Electroning that layer would refactor GUI code for no GUI benefit, and running as main is what keeps the CLI on the SAME paths and packages the GUI uses. Every command forwards into an editor component rather than restating it: - `devices` -> `discoverRuntimes`, extracted out of `MainProcessBridge` so the GUI's Search button and the CLI run one scan. - `compile` / `upload` -> `CompilerModule.compileProgram`, preceded by the renderer's own pre-compile chain (`injectLibraryCppBlocks` -> `preprocessPous` -> `toIpcProjectData`, now exported from the compiler adapter) and `LibraryManagerModule` for archive resolution. `upload` is the same call with a runtime address, not a second flash path. - project loading -> `ProjectService.readRawProjectFiles` + `parseProjectFiles` + a real store hydrated through `sharedWorkspaceActions.handleOpenProjectResponse`, so `getCompileReadyProjectData()` is literally the GUI's call. Alias resolution needs device state (board, pin mapping, VPP screens), which is why the store is stood up rather than reconstructed. - `debug` -> `WebSocketDebugTransport`, the debug map via `parseDebugMap`, and values via the shared codec. Two extractions were forced by finding real drift: - `RuntimeApiClient` (`backend/editor/runtime/`): the runtime REST layer lifted out of `MainProcessBridge`, which now delegates. While the CLI briefly had its own copy it POSTed to `/api/start-plc` (the runtime answers GET) and read HTTP 200 as success, missing that refusal arrives in the body (`START:ERROR_SWITCH_STOP`). Both are invisible without hardware. - `walkDebugResponse` (`frontend/utils/`): the positional walk over a `getVariablesList` reply, now shared with `useDebugPolling`. `lastIndex` handling, consumed-but-undecodable slots, the short-buffer stop and the endian swap are silent-corruption bugs when two callers disagree. Debug is session-first: `debug open` forks a daemon holding the channel and returns a `session_id`; one-shot commands dial its socket; the REPL is another client of the same protocol. `close` releases the session's forces by default, because the runtime clears them only on program unload/stop and cannot notice a debugger leaving. Verified against a live SLM-RP4 (v4.1.9) at 192.168.2.4: discovery, compile (50 debug leaves, VPP plugin sources, bundle composed) and upload all succeed. `debug open` correctly refuses while the device's physical mode switch is in STOP, and says so.

A compile-only build for a runtime-v4 target left almost nothing in `build/<target>/`. The bundle is composed in memory by `composeRuntimeV4Bundle`, and the only thing that ever wrote it to disk was `uploadRuntimeV4` — which the compile-only branch returns before reaching. The folder was left holding just the files `packageVppPlugin` writes directly (`conf/`, `vpp_plugin/`, `vpp_plugins.conf`): 17 files instead of 51, missing `program.st`, the generated C++, `defines.h`, `configuration.cpp`, the strucpp runtime headers and — the one a debugger needs — `debug-map.json`. It hid well. Any earlier build-and-upload leaves a complete folder behind, so a compile-only run over a dirty build directory looks correct; only wiping the folder first shows it. Split the write into `CompilerPlatformPort.materializeRuntimeV4Bundle` and call it for every v4 compile, before the compile-only branch, so `compile` and `upload` leave byte-identical artifacts. `uploadRuntimeV4` no longer writes the bundle itself — the files it zips are already there. The port method is optional so a platform without a project build directory is unaffected. Fixes the editor's Build -> compile-only as well as the CLI's `compile`.

A CLI command should kick off the same orchestrated flow as the GUI control it mirrors, not reassemble the steps. `compile` / `upload` were reassembling them — board lookup, the library C++ graft, POU preprocessing, pipeline argument shaping — which is how they ended up passing `boardCore: null` and guessing `isSimulator` from the target name while the GUI derived both from board info. Extract that orchestration out of the editor's `CompilerPort.compileProgram` into `compileProgramFlow`, parameterised by a three-call transport. The renderer adapter supplies a `window.bridge` transport; the CLI supplies one backed by the main-process modules. Same flow, two front ends: `build.ts` drops from 280 lines to 161 and no longer knows what a board core is. Also adds `debug exec`, the scriptable counterpart to the REPL. Piping a script into `debug repl` silently dropped commands — readline over a non-TTY delivers buffered lines in one burst, so pausing between them cannot hold them back; a seven-command script ran the first and the last. `exec` reads the whole input and runs it strictly in sequence, and the REPL now refuses a pipe and points at it rather than degrading. Two bugs found by running against a live SLM-RP4: - `force` reported the pre-write value. External writes land on the runtime's debug-write journal and drain once per cycle, so the immediate read-back races the drain: `force x 3.5` answered `0`. It now polls briefly for the value to settle, and gives up quietly (a soft `write` the program overwrites next scan is not an error). - A session kept reporting `[FORCED]` after stopping the PLC. The runtime clears forces on program unload/stop, so the list was stale — a forced BOOL read back as the program's own value while still flagged, and `close` tried to release pins that no longer existed. Stopping the PLC now clears the session's list. Verified end to end on the device: open, status, list-vars, read, write, force, unforce, watch + poll (capturing transitions between separate invocations), start, stop, exec, close. A fresh session confirms `close` really released the pin on the runtime, not just in bookkeeping. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Three drifts, one cause — the CLI holding an opinion the editor already has.
**Debug transport was hardcoded to the v4 WebSocket.** It worked against a
runtime v4 and silently made every baremetal board undebuggable from the
terminal, though the editor debugs them fine. Transport is a property of the
TARGET: it lives in `hals.json` / VPP manifests and is read by
`resolveRuntimeDebugChannel`, with `toDebugCandidate` building the channel.
`debug open` now calls both, so Modbus RTU, Modbus TCP, the v4 WebSocket and the
in-process simulator all come from the same resolution the GUI uses.
`toDebugCandidate` / `toDeviceLinkCandidates` are extracted out of
`MainProcessBridge` (which now delegates) with the simulator's virtual serial
port injected, since that belongs to whoever hosts the emulator.
**Variable identity was the raw debug-map path.** It is now the COMPOSITE KEY
the GUI shows — `main:SL1_AO1`, from `buildDebugVariableTreeMap` +
`deriveVariableIndexMap`. A test asserting on names nobody sees in the editor was
the wrong contract. Raw paths still resolve, because `deriveVariableIndexMap`
keys them as a fallback for leaves the tree does not surface.
**Build did not warn like the GUI.** Targets that build on the device now refuse
while the PLC is RUNNING, with the same reasoning the editor's dialog gives, and
`--yes` / `-y` approves stopping it first the way `apt -y` does. Silently halting
someone's running PLC is not a default.
Making the editor's resolvers usable meant hydrating the SHARED store rather than
a private instance: `buildDeviceResolverContext` and the debug tree builder both
read `useOpenPLCStore.getState()`. `loadProject` now seeds `availableBoards` too,
exactly as the workspace screen does on load, and the daemon hydrates before
resolving. One project per process is the assumption the editor already makes.
Also keeps forced names in their canonical casing, so `status` reports
`main:SL1_AO1` and not an uppercased form.
Verified on the SLM-RP4: channel resolved from the spec ("Opening the debug
channel (websocket 192.168.2.4)"), reads and forces by composite key, raw-path
fallback, upload refused while RUNNING (exit 7) and accepted with -y after
stopping the PLC.

… them Verified the transport-agnostic debug work against a P1AM-100 on /dev/cu.usbmodem11301, which surfaced three things the network-only testing could not. `devices` listed network runtimes only. It now also lists serial ports, from `HardwareModule.getAvailableSerialPorts` — the same call behind the editor's port dropdown, labels included (the P1AM-100 identifies as "Arduino MKR Zero", sharing the SAMD bootloader's USB id). The command exists to answer "what do I pass to --host or --port", and half the answer was missing. `--port` is that dropdown, and it has to land in the STORE, not just in the compile arguments: the debug-spec resolver reads `configuration.communicationPort` from there, which is how a board's declared serial channel learns which port it is on. `applyConnectionOverrides` mirrors what the device screen does. `upload` demanded `--host` unconditionally, which made it unusable for every Arduino-class board. Which arguments an upload needs is a property of the target and the editor already answers it — `directUsbUpload` distinguishes a board flashed over USB (arduino-cli, needs a port) from one reached through a runtime API (needs an address and credentials). Credentials are no longer demanded from a target that has nothing to log in to. End to end on the P1AM-100: compile (hex/bin + debug-map), upload over USB (flash verified), `debug open --port` with no host resolving to `rtu /dev/cu.usbmodem11301` from the board's spec, reads by composite key, run/stop over FC 0x4b on the debug channel rather than REST, and a force on `en_sinal` starting the program's pulse generator with the ~500ms blink captured in the watch buffer and drained by `poll` from a separate process. `close` released the pin, confirmed from a fresh session.

"Electron quit unexpectedly" was a real bug of mine, not a transient. macOS recorded SIGABRT with an uncaught C++ exception thrown from `node.napi.node` inside `node::Environment::CleanupHandles` — `@serialport/bindings-cpp` releases its handle asynchronously and registers a NAPI async cleanup hook, and tearing the Node environment down mid-close makes that hook throw. An uncaught C++ exception aborts the process, so nothing of ours appears in any log. `ModbusRtuClient.disconnect()` called `serialPort.close()` fire-and-forget and dropped the reference, which is harmless in the editor — a GUI keeps running afterwards. The CLI's whole job is to disconnect and exit, so it hit the window every time: `debug close` awaited nothing and called `app.exit(0)` in the same tick. - `disconnect()` now passes the close callback (so a failure is handled instead of surfacing as an `error` event on a port already dropped) and exposes `closed()`, resolving when the handle is actually released. - `disconnectAndWait()` awaits that under a 2s bound — a handle that never closes must not hang teardown — and is used by every path that closes a channel before exiting, including `openDebugSession`'s failure paths, which had the same window. Proven causal rather than assumed: reverting just this fix reproduced the crash with an identical `node.napi.node` -> `__cxa_throw` stack, and also hung the next `close`, because the aborted daemon left the port held and its socket stale. Restored, six serial open/close cycles produce no crash report. The GUI was never affected — same binary, different process. 402 GUI-path tests and 4642 overall still pass.

RUNTIME_TLS_REJECT_UNAUTHORIZED policy instead of hardcoding rejectUnauthorized.
Replace the local RUNTIME_DEBUG_PORT usage with the exported RUNTIME_API_PORT

import direction requires it.
In `@src/backend/editor/runtime/runtime-api-client.ts`:

the request-options objects used by the request calls, and introduce a typed
local Uint8Array collection for the Buffer.concat inputs instead of the double
assertion. Preserve the existing request behavior and concatenation order.

configuration mapping to accept only finite, non-negative numeric values;
otherwise retain the existing 0 fallback. Use a finite-number check together
with a >= 0 validation before assigning record.idleTimeoutMs.
- Around line 23-36: Add an error listener within readFirstLine that resolves
the promise with an empty string when process.stdin emits an error, preventing
an unhandled stdin error from terminating the daemon. Keep the existing newline
and end handling intact, and ensure the listener is detached once the promise
settles.
In `@src/cli/debug/close-channel.ts`:
- Around line 39-49: Update delay to unreference the setTimeout handle so the
timeout does not keep the event loop alive after closed() wins the Promise.race;
preserve the existing referenced-yield behavior for the separate delay(0) call.
In `@src/cli/main.ts`:
- Around line 276-280: Update the createProcessReporter options in the main CLI
flow so noJson is derived using the same boolean-aware parsing as json, treating
both --no-json and --json=false as human mode. Reuse boolFlag for the json flag
while preserving the existing behavior for explicit true and absent values.
- Around line 221-229: Update the decoder callback in makeRuntimeApiRequest to

startup flow to before loadProject and openDebugSession begin, and update
shutdown to safely handle an uninitialized channel while startup is still in
progress. Preserve normal cleanup once the channel exists.
In `@src/cli/session/registry.ts`:
- Around line 50-52: Replace the type assertion in the catch block with a
narrowing guard such as isErrnoException, defined near the containing function,
and check the error code only after the guard succeeds. Preserve the existing
EPERM boolean result and ensure non-Error or unrecognized caught values return
false.
In `@src/cli/session/server.ts`:
- Around line 116-122: Update Server.shutdown to be idempotent by adding a
shutdown-completed guard that returns immediately on subsequent calls, and set
it before performing cleanup or invoking options.onClosed(). Preserve the
existing timer, socket, server, and callback cleanup behavior for the first
invocation.
In `@src/cli/spawn-session.ts`:
- Around line 66-73: Attach an error listener to child.stdin before writing the
serialized config in the spawn flow, handling asynchronous pipe failures such as
EPIPE without allowing an uncaught exception. Integrate the handling with the
existing child exit reporting so the CLI remains controlled when the daemon
terminates early.

- Around line 136-150: Remove the duplicate token-refresh subscription from the
RuntimeApiClient constructor while retaining the onTokenChanged handler in the

The packaged story did not work. `cli.js` was emitted into `app.asar` at
`dist/main/cli.js`, but a packaged Electron app always runs
`package.json.main` — its binary cannot be handed a different script — so
nothing could start it. The debug daemon's respawn had the same hole: for a
packaged build it passed the app binary a script path, which Electron ignores,
so it would have launched the GUI in the middle of a headless run (the failure
already fixed for dev).
Both roles now ship in one binary and argv decides. `src/main/entry.ts` is the
app entry and imports the GUI only when this is not a `--cli` / `--cli-daemon`
run — both modules do their work on import, so importing both would start both.
OpenPLC Editor.app/Contents/MacOS/OpenPLC\ Editor --cli devices
`daemonSpawnArgs()` passes the marker alone when packaged, and the script path
only in development.
Renamed to `openplc-cli` throughout the usage text and messages: `openplc` reads
like the runtime or the app, and the name should say what it is.
`--help` behaviour completed:
- `-h` works. It previously fell through to positionals, so `-h` was read as the
command "-h" and exited 2 instead of printing help and exiting 0. Short flags
are now an explicit two-entry map (`-y`, `-h`) rather than a general `-x` rule.
- An unknown command prints the usage as well as the error, since a mistyped
command is exactly when the list of real commands is useful.
- Exit codes: `--help` / `-h` → 0, no arguments → 2 (a script invoked with an
empty argument must not read as success), unknown command → 2.
Verified on the production bundle: `--cli` runs headless with no window, the GUI
still boots and exits cleanly through the new entry, and a serial debug session
opens, reports status and closes with the daemon respawning through the
dispatcher and spawning no window.

…y OS
`--cli` worked but nobody would type
`OpenPLC Editor.app/Contents/MacOS/OpenPLC Editor --cli`. The app now puts an
`openplc-cli` command on PATH on first run, and `openplc-cli install-cli` does
it explicitly for a CI image that never launches the GUI.
**User-writable locations only** — `~/.local/bin`, `~/bin`, or
`%LOCALAPPDATA%\Programs\openplc-cli`, preferring whichever is already on PATH.
No `/usr/local/bin`, no Program Files: a convenience command is not worth an
elevation prompt at launch, and an install needing root fails on locked-down
machines and succeeds inconsistently elsewhere. Windows gets its per-user PATH
updated via PowerShell's `SetEnvironmentVariable` (never `setx`, which truncates
at 1024 characters and would silently eat a developer's PATH); POSIX gets the
one line to add, because editing someone's `.zshrc` unasked is not an install
step. An existing `openplc-cli` that is not ours is left alone.
**Ephemeral app locations are refused, with a reason.** A shim is only as durable
as the path inside it:
- macOS disk image (`/Volumes/…`) — the app is not installed yet; the shim would
break on eject. The GUI shows a dialog saying to move it to Applications.
- macOS app translocation (`…/AppTranslocation/…`) — Gatekeeper runs a
quarantined app from a randomised path that changes every launch. This looks
like a normal launch, which is why it needs naming.
- Linux AppImage — the MOUNT is ephemeral, but the `.AppImage` file is not, and
the runtime exports it as `$APPIMAGE`. The shim targets that (the same
mechanism electron-builder's updater relies on). Only a temporary mount with
`$APPIMAGE` unset is refused.
Three things a Linux container test caught, none of which macOS could show:
1. **Electron cannot start without a display, even with no window.** Ozone
initialises during startup: "Missing X server or $DISPLAY. The platform failed
to initialize." The shim passes `--ozone-platform=headless`, so callers need
no `xvfb-run`.
2. **Chromium's SUID sandbox aborts in containers.** The shim passes
`--no-sandbox`, safe for this process alone — it creates no renderer and loads
no web content. The GUI never takes that path. Both switches must be on the
command line: set from JS they are too late, which is why they live in the
shim rather than in `app.commandLine`.
3. **The CLI's own parser swallowed its command.** `--disable-gpu` is not a
declared boolean flag, so it consumed the following token: `--cli install-cli`
arrived as `disable-gpu=install-cli` with no command, printing the usage and
looking like a typo. `cliArgv` now slices at the `--cli` marker — everything
before it belongs to Electron.
Also: `-h` (which previously became the *command* "-h" and exited 2), usage
printed on an unknown command, and exit codes settled — help 0, no arguments 2,
unknown command 2.
Verified in a debian:12 arm64 container against a packaged build: headless run,
install-cli, the generated shim, `openplc-cli` as a plain PATH command in both
output modes, exit codes, `devices` exercising the serialport binding, an
idempotent re-install, `$APPIMAGE` targeting the file, and a temporary mount
being refused with an explanation and no shim written.
Note for release: cross-building Linux from macOS packages the *macOS*
`@serialport/bindings-cpp` binary ("invalid ELF header"). A Linux artifact must
be built on Linux; the container test used the correct prebuild.

…lling it The shim already carried the Linux switches, but reaching `install-cli` in the first place meant calling the app directly — and that call needed them too. A chicken-and-egg the install instructions would have had to explain. A direct `--cli` run now re-executes itself with the switches it is missing. That fixes the case that actually bites: `--ozone-platform=headless`. Electron initialises its display layer AFTER this script runs, so without a DISPLAY (an SSH session, a CI runner) a direct call could not start; with the relaunch it does. Verified in a container with no DISPLAY. `--no-sandbox` is not fixable that way and the comment now says so rather than implying otherwise: Chromium's SUID sandbox check runs before any JS, so a launch that fails it has already aborted. It only fails where unprivileged user namespaces are unavailable — Docker's default seccomp profile — because with them Chromium uses the namespace sandbox and needs no helper. Confirmed by running the same image with `--security-opt seccomp=unconfined`, where the plain call succeeds. Those callers pass `--no-sandbox` once, to create the shim, which carries it from then on. Adds `docs/CLI.md`: the button-to-command mapping, install procedure per OS (including why a macOS disk image and a moved AppImage are refused), the output contract and exit codes, credential handling, debug sessions and the force-release rule, and the `--yes` gate. Both documented Linux paths verified end to end in a debian:12 arm64 container against a packaged build: the plain call where user namespaces are available, and `--no-sandbox` once where they are not — after which `openplc-cli --version`, `devices` and `-h` all work with no switches.

…ompile `compile` failed on any machine the editor had never run on: `ENOENT … User/Runtime/arduino-core-control.json`, exit 70. `UserService` creates that scaffolding (settings, history, the arduino-cli config) and the GUI instantiates it at startup; the CLI never did. It went unnoticed because every machine I had tested on had run the GUI before, so the files were already there — a fresh CI container is the first place it shows. The CLI now runs the same initialisation, AWAITED rather than fire-and-forget. `UserService`'s constructor starts the work without exposing a way to wait for it, which is harmless for a GUI (a window takes far longer to appear) and not for a CLI that can reach the compiler in the same tick. Added `UserService.initialize()` for that; the constructor still starts it, so the GUI is unchanged. Fixing it also corrected an exit code: a bad `--target` returned 70 (internal) because the ENOENT fired before target resolution. It now returns 3 (not found), which is what a pipeline should branch on. Verified in a debian:12 arm64 container, as root AND as an unprivileged user, with no DISPLAY, no TTY and stdout piped: `compile` exits 0, stdout is exactly one parseable JSON document, progress and Chromium's D-Bus noise stay on stderr, 36 artifacts land including `debug-map.json`, and failures exit 3. Documents the pipeline setup in `docs/CLI.md`: the shared libraries a slim image needs, why `--no-sandbox` is required for the one install call in a container but not on a desktop, and reading the result with `jq` off a single-document stdout.

One conflict, in `main.ts`'s `toDebugCandidate`, and it was semantic: this branch extracted the method into `debug-channel-factory` (shared with the CLI) from a copy taken BEFORE #1023, while `development` had meanwhile changed the same lines to read the runtime token at channel-open time. Resolved by keeping the extraction and giving the factory a `getToken` seam, so #1023's behaviour is preserved rather than reverted: the main process passes `this.runtimeApi.tokens.getToken()`, the CLI passes its own client's manager, and `config.connectionParams.jwtToken` stays only as the first-instants fallback. Without that seam a v4 debug channel opened after a transparent re-login would present a stale JWT, and the runtime re-verifies on every command — killing the session and the licensing PDUs that ride the same socket. Verified all five of #1023's pieces survive the extraction: `isLicenseChannel`, the `LicenseChannel` type, `reauth?.(newToken)`, `debugHolderSeq`'s `what#seq` holder suffix, and `withLicenseChannel`.

…erbs Four defects, all found by re-testing on real hardware after the merge. **The CLI could hang forever.** `openplc-cli --help 2>&1 | head -3` never returned. `head` leaves, the pipe closes, the next write raises EPIPE — and the reporter's attempt to report THAT raises EPIPE too, so `main()` rejected, `void main()` swallowed it, and an Electron main process with no window simply idles. In a build pipeline that is not a failed step, it is a job that burns its timeout and reports nothing. Guards now make every path exit: EPIPE on either stream exits Ok (the reader asked for a prefix and got it — `pipefail` must not see a failure), and `unhandledRejection`/`uncaughtException` exit Internal. Reproduced before, 1s after. **The runtime token regressed to the login-time value.** The merge resolution kept the extracted `debug-channel-factory` and added a `getToken` seam to carry #1023's token-manager read — but the factory's websocket branch never consulted it, so the behaviour was reverted while looking preserved. A channel opened after a transparent re-login presented a stale JWT, and the runtime re-verifies on every command, so the session and the licensing PDUs sharing the socket die on the first one. Now read through the seam at open time. The build-time guard widened with it: the manager is the authority, so a config carrying no token is still openable when a session exists, and `create()` throws rather than opening an unauthenticated socket if the token vanishes in between. Tested, because nothing observable broke when this regressed — which is exactly why it did. **"websocket websocket 192.168.2.4".** Both branches of `toDebugCandidate` spelled the transport into `descriptor`, and every display site pairs the two fields itself. Descriptors are the endpoint alone now, matching the link candidates they are built from — where the convention is load-bearing, since one is compared against a raw OS port path. **`read` was an unknown command inside `debug exec`.** The REPL mirrors `strucpp`'s verbs (`vars`/`get`/`set`) while the subcommands are `list-vars`/`read`/`write` — one operation, two vocabularies, and a caller who learned the subcommand got "Unknown command" the first time it typed the same word into `exec`. Both spellings now parse to the same protocol request, held there by a test. Also R17: the 10-element positional compile-args array was re-declared with a different element union at all four hops, which is why passing it along needed `as never`. One labelled tuple, `CompileProgramIpcArgs`, declared once and imported by the flow, the adapter, the renderer bridge and the IPC handler — a reordered slot is now a compile error instead of a corrupt build, and the cast is gone rather than justified. Hardware-validated on an SLM-RP4 (websocket) and a P1AM-100 on /dev/cu.usbmodem11301 (rtu): compile, upload, open, status, list-vars, read, write, force, unforce, watch+poll (9 blink transitions over serial), start, stop, exec, close.

… print help
Found by running the CLI in a Debian container with no DISPLAY, no TTY, piped
stdout and — the part that mattered — no arduino-cli and no udevadm, which is
what a build agent actually looks like.
**Log lines were landing inside the JSON.** `openplc-cli devices | jq` broke on
that container: two coloured Winston lines ("arduino-cli board list failed",
"Failed to enumerate serial ports") came out on STDOUT, wrapped around
otherwise-valid JSON. Winston's Console transport sends everything except the
levels named in `stderrLevels` to stdout, and none were named. Every level goes
to stderr now. Diagnostics are still reported — three of them on that container
— just not into the channel that promises exactly one JSON document. Nothing
showed on a developer machine, where both tools exist and the logger stays
quiet.
**`--help` shelled out to arduino-cli, twice, and died when it was missing.**
`UserService`'s scaffolding refreshes a cache of installed cores and libraries
by running `arduino-cli core list` and `lib list`. Two problems: the constructor
starts that work AND `initialize()` started it again, so every invocation ran
the whole thing twice — four processes to answer `--help`, and every "file
already exists" warning printed twice. Both entry points now share one run.
Then the run itself was fatal: promisified `exec` rejects when the binary is
absent, so the awaited `initialize()` took the process down with exit 70 —
`--help`, `--version` and `devices` included, none of which need a compiler.
The two shell-out steps are now tolerated with a warning, which is what the GUI
already did by accident (its rejection swallowed by a fire-and-forget
constructor). And an invocation that only describes the CLI itself skips the
scaffolding entirely: printing usage should not create directories.
Linux validation, root and non-root (uid 1000), headless, stdout piped, 8/8:
`--help` exits 0; no arguments and an unknown command exit 2; `--version` and
`devices` each put one parseable JSON document on stdout; a missing project
exits 3; a closed pipe returns in under a second; `install-cli` writes a shim to
~/.local/bin only, and `openplc-cli --version` then works by name with no flags
from the caller — the headless switches are inside the shim.

The dev bundle entered at `cli/main.ts` while the packaged binary enters at `main/entry.ts`, so everything only the dispatcher does went untested by the bundle used to test everything else. The dev entry is `entry.ts` now (`--cli` required, as the packaged binary requires it), and two defects surfaced immediately. **A failure to load hung the process.** Electron's reaction to an exception escaping the main script is to print "App threw an error during load" and show a message box — right for a GUI, but for a CLI it is a modal dialog with nobody to click it, so the process sits there having produced no output and no exit code. The dynamic import is now caught: message on stderr, exit 70. It works because the import is dynamic — the handler is registered before the CLI's own imports evaluate. Verified with an induced module-evaluation throw: exit 70 in 2s with the error on stderr, and Electron's own handler never reached. That guard covers throws from the CLI's own module graph. It does NOT cover the two webpack `externals`: the UMD wrapper both this bundle and the shipped `main.js` carry requires `serialport` and `socket.io-client` in its factory call, before any of our code runs, so a missing or arch-mismatched native module still takes the old path — on Windows, the hang described above. Reaching that needs a broken installation, and fixing it properly means dropping the pointless UMD wrapper from the main bundle (nothing imports it as a library), which is a packaging change that wants its own PR and a package build per platform. **`install-cli` on Linux generated a shim with no script in it.** The Linux re-exec puts the headless Chromium switches ahead of everything else, so `process.argv[1]` — where this looked for the bundle — was `--no-sandbox` by the time it ran, and the emitted shim was `electron --cli "$@"`. Electron handed no script hangs rather than erroring, so the installed command would have sat forever instead of saying what was wrong; the code even warned about that failure mode two lines above the bug. The script is now found by shape (the first `.js` argument) rather than by position. Invisible until now because the old dev entry never re-execed and a packaged build takes the `isPackaged` branch. Re-validated after both fixes — macOS (devices, exit codes 0/2/2/3, closed pipe returns in 0s) and Debian as non-root with no DISPLAY (8/8, plus the installed shim invoked by name: `openplc-cli --version` and `openplc-cli devices` both exit 0 with one JSON document each).

Verified on Windows 11 24H2 (exit codes 0/2/2/3/0, one JSON document per command, usage on stderr, closed pipe returns in ~3s). Also documents that a .bat/.cmd caller needs 'call' before the shim — batch invoking batch without it transfers control instead of returning, so the rest of the script silently never runs and %ERRORLEVEL% is never seen. Same caveat as npm.cmd; not specific to this shim, but worth stating where someone will script against it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The remaining review findings, the first of which is the serious one.
**The watch timer raced every client request.** The debug channel is ONE
request/response link, and `SessionServer` queues client requests for exactly
that reason — but the timer was a second actor that went straight to
`readValues`, so a sample could be in flight while a read, a write, a force or
an MD5 probe was in flight. Two overlapping exchanges on a one-at-a-time link do
not fail cleanly: the frames interleave and BOTH replies decode wrong, which for
a debugger means confidently reporting values that were never on the wire.
Nothing throws, so nothing noticed.
`SessionCore` now owns a chain that both actors acquire. `handle` takes it for
the whole dispatch rather than per channel call, because a write reads back
until the value settles and a sample landing between the set and the read-back
would be answering from the middle of someone else's exchange. The chain is a
queue, not a re-entrant lock, so exactly two places acquire it — which is the
point, they are the two independent actors — and the external close paths (the
idle timer, SIGTERM) go through `closeFromOutsideRequest` because watching is
not activity: a session can be idle by the timer's reckoning while its watch
timer is still using the channel.
Sampling also had no backpressure. The interval floor is 20 ms and a batched RTU
read takes far longer, so ticks piled up and every one eventually fired — a
burst of samples all stamped with the time they finally ran, describing a signal
that never looked like that. A tick is now dropped while one is pending.
Pinned by tests that fail without the fix: 2 of the 3 go red when the sample
path bypasses the chain. Then confirmed against an SLM-RP4 with a 100 ms watch
while reads and a force were hammering the same channel — 165 samples, zero
decode failures, intervals 98-113 ms. Serialised, not starved.
**The request queue could be poisoned.** `enqueue`'s comment asserted the chain
never rejects; nothing enforced it. `core.handle` answers its own failures, but
`write` can still throw — `socket.write` after a peer teardown, or a response
carrying something `encodeMessage` cannot serialise — and one escaped throw left
the queue rejected, so every later `.then(callback)` skipped its callback: the
session stayed connected, answered nothing, and Node logged an unhandled
rejection. Indistinguishable from a hang, from the client's side. Now caught,
the link dropped, and the chain always resolves.
**Runtime responses were asserted, not validated.** `JSON.parse(...) as
{ access_token: string }` claimed a shape without checking it, so a 200 with an
unrecognised body produced a session holding `undefined` as its token and failed
later as "cannot read property of undefined". Both parsed responses now go
through zod schemas, with an unparseable login reading as a failed login.
**The multipart header interpolated a filename raw.** A `"` closes the quoted
string early and a CR/LF ends the header line, either of which corrupts the body
the runtime tries to parse. Sanitised — stripped rather than rejected, since the
filename is a label on a bundle we are already committed to sending.
Also removed the `as unknown as ReadonlyArray<Uint8Array>` on `Buffer.concat`,
which CLAUDE.md forbids and which was hiding a TS/@types/node iterator mismatch:
a zero-copy `Uint8Array` view satisfies the signature honestly, without copying a
firmware bundle to appease a type.

Included review availability: Your plan provides up to 2 included reviews per hour; 1 remains after this review.
The last of the review findings, plus one bug they led me to that was live on my own machine. **`--no-sandbox` was added to every Linux CLI run.** `relaunchForLinuxCli` prepended the whole switch list whenever any of it was missing, so a plain `--cli` call relaunched itself with the sandbox off. It could never have helped: Chromium's SUID check runs before any JS, so a launch that fails it has already aborted — the switch in that list only ever disabled the sandbox for the runs that did not need it. Removed from the automatic relaunch; a switch the caller supplied still survives, because `process.argv.slice(1)` passes it on. The environments that genuinely cannot start the sandbox (Docker's default seccomp blocking unprivileged user namespaces) pass it themselves once, to install, and `install-cli` now records that in the shim it writes — so the switch follows the environment that needs it. Verified both ways in a container: with `--no-sandbox` at install the shim carries it forward; without it (and with `--security-opt seccomp=unconfined`) the shim has no such switch and the CLI runs with the sandbox ON. **A dev launch installed a shim that could only hang.** `installCliShimOnFirstRun` was documented as packaged-only and never checked, so `npm run dev` wrote `exec .../node_modules/electron/dist/Electron --cli "$@"` — Electron with no application, which hangs rather than erroring — over whatever working shim was there. Found because it happened to this machine during testing (the broken file has been regenerated). Now guarded on `app.isPackaged`. **An EPIPE could kill a daemon holding forced variables.** `spawn-session` destroys the daemon's stdout once the session is registered, so the next idle-timeout diagnostic writes to a closed pipe. Worse, the EPIPE guard added earlier in this branch would have EXITED there — and a session killed mid-flight leaves its forces pinned, because the runtime clears a forced slot when it is told to, not when its debugger disappears. Losing that pipe is expected for a daemon, so it is now ignored there and still exits for a one-shot command. **A failed relaunch reported nothing.** `result.status` is null when the child cannot be created or dies on a signal; the code exited `1`, which is not one of this CLI's documented codes, and dropped the reason. Now reports the error or signal on stderr and exits 70. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
**`create` overwrote an existing project without a word.** The service writes
into whatever directory it is handed, so `create` aimed at an existing project
replaced its `project.json` and device files silently — one mistyped `--path`
away from taking a real project with it. An existing destination is now refused
(exit 2), with `--force` to say you meant it. Verified: refusing leaves
`project.json` byte-identical, and `--force` reproduces the same project the
first create made.
Its error classification was wrong too: an unwritable `--path` exited **70**,
which this CLI's contract reserves for "a bug in the CLI, not your input". First
attempt classified it by pattern-matching the failure text, which does not work —
the service reports "Failed to create project file at …" with no errno in it. So
writability is now settled BEFORE the service runs, by probing. That probe
already existed in `cli-shim/install-shim`, so it moved to
`backend/editor/utils/directory-writable` and both callers share it rather than
keeping two copies of the same three awkward details (absent directories judged
by their nearest existing ancestor, `access(W_OK)` lying on network filesystems,
cleaning up the probe file).
**A throw while BUILDING the debug channel killed the daemon.** `create()` sat
outside the try that guards `connect()` — and this branch is what made that path
throw ("log in again" when the token manager is empty). `runDaemon` awaits with
no try/catch, so the process would have died without announcing a reason, and
the parent would report a bare exit code for what is really an auth problem.
**A rejected channel close threw away the released-forces list.**
`ModbusRtuClient.closed()` hands back a promise that can reject, and
`SessionCore.close()` awaits it AFTER collecting which forces it released — so a
failed native close reported a failed close for a session that closed fine, and
lost the list of what it had unpinned. The race now swallows, and cancels its
loser: a pending 2-second timer was holding the event loop open after `closed()`
had already won.
**`close` said "(record removed)" for records it had kept.** Fallout from this
branch's own timeout fix: a timeout correctly retains the record now, but the
output still claimed otherwise — telling a caller its only handle on a live
session was gone. The outcome is tracked and rendered per record, and carried in
the JSON as `recordRemoved`.
The remaining five are type-safety findings against CLAUDE.md, none of which
changed behaviour today but two of which were holes:
- the runtime-version response header was asserted to `string`, though
`IncomingHttpHeaders` values can be `string[]` — a header sent twice was
reported, and compared, as a comma-joined array;
- `compile-program-flow` asserted four IPC fields. `firmwarePath` is handed to
the simulator as a filesystem path and `logLevel` flowed through unchecked;
`compileError` drives click-to-open, so a partial object cast to the type gave
the console coordinates that navigate nowhere. All narrowed, the structured
error rebuilt field by field so an unexpected key cannot ride along;
- `RUNTIME_DEBUG_PORT = 8443` duplicated the exported `RUNTIME_API_PORT` — one
port on one device, two constants that could only drift;
- the `wireFormat` switch had no `never` check, so a type added to
`IEC_BASE_TYPES` would have returned `undefined` against a
`boolean | number | string` signature rather than failing at the switch;
- two tuple-membership tests used widening casts; both are predicates now.
Hardware-validated on the SLM-RP4 after the changes: open, force, close still
reports the force it released. `create` exercised through all four states (fresh,
existing, `--force`, unwritable) and the stale-record close path through its
ENOENT branch.

Verification of round 2 — all 34 findings re-checked, both suites executedScope: every round-1 finding re-verified against The round-2 work is genuinely good.

**B2 — `--idle-timeout` could not be set, and a typo was silent.**
`Number(raw) || DEFAULT` sent `0` to the default, because 0 is falsy — so "never
close on idle", which the server supports via `timeout <= 0`, was unreachable —
and turned `--idle-timeout 5min` into a silent 30 minutes. That matters because
a session closing RELEASES ITS FORCES: a soak test asking for no timeout had its
outputs handed back mid-run, on live hardware. Parsed properly now, and a value
that is not a number is a usage error rather than a silent fallback. Writing the
test found one more: `Number('')` is 0, so `--idle-timeout=` would have meant
"never close"; empty is rejected explicitly.
**A1 — `debug close` exited 0 when it could not close.** `runClose` ended in an
unconditional `success`, so a session that would not answer — forces still
pinned on a live PLC, which is the outcome the release-on-close rule exists to
prevent — was reported to the harness as done. The reporter had no way to say
"some of it": `partial()` now emits the same payload a success would, with `ok:
false` and `ExitCode.TargetError`. Measured before (exit 0) and after (exit 7).
**R9 — the same typo answered 3 from `compile` and 70 from `debug open`.**
`TargetUnknown`, `ProjectInvalid` and `ProjectNotFound` had no case and fell
through to 70 — documented as "a bug in the CLI, not in the caller's input".
Both are 3 now, measured.
**E1/E2 — two leftovers this branch created.** `runtime:token-refreshed` fired
twice per refresh (the extraction added a constructor listener while #1023's
registration stayed, on the same manager); the constructor option had no other
caller, so it and its empty options interface are gone. And three constants sat
in `main.ts` with zero references after their call sites moved — one of them the
`8443` this work claimed to have unified. It is now imported from one place
everywhere, including `discover-runtimes` and `compiler-module`, which restated
it a third and fourth time.
**A2 — `debug exec` with no argument waited for a terminal to type into.** It
defaults to stdin, and nothing rejects, so no guard could rescue it. It refuses
an interactive stdin now and prints the two forms that work, mirroring the check
`debug repl` already had for the opposite case.
**A3 — `debug list` kept sessions alive for ever.** Listing dials each session
for its state, which reached the idle timer, so a harness polling `list` in a
loop reset every timeout it was polling. `status` carries `probe` now; the server
arms the timer for everything else. `SessionCore` was already careful that
watching is not activity — being listed is not either.
**N5** — the comment naming `loopReachedEnd` describes `reachedEnd`. Shared
surface, mirrored.
**R5** — the 30-minute idle timeout is documented, with what does and does not
count as idle, plus a table of the 16 flags. All 16 verified to exist.
**The minor set — 7, none of them behavioural today:** `shutdown()` is
idempotent (the close request and the idle timer could both reach it);
`registry.ts` reads `code` without a cast; the daemon's signal handlers are armed
BEFORE the channel opens, so a SIGTERM during a slow open no longer leaves it up
with forces pinned; `idleTimeoutMs` off the config line must be finite and
non-negative (`setTimeout(NaN)` fires immediately); `child.stdin` has an error
listener, so a daemon that dies before reading its config reports the real cause
instead of an uncaught EPIPE; `--json=false` selects human mode (it arrives as
the string `'false'`, so `=== false` never matched); and the Windows build path
is built with `join` rather than a hardcoded `/`.
Verified on an SLM-RP4: open with an explicit idle timeout, `list` reporting PLC
state and forced set, read, force, close releasing what it forced (exit 0), and
SIGTERM on the daemon — which exited, unregistered, and left `main:en_sinal`
unforced on the device, confirming the teardown reordering.
6871 tests pass (the same two pre-existing failures), plus 13 new for the two
policies. Shared surface: 0 diffs over 1052 files.

**R19 — the seam is a type now, not a `ParsedArgs` literal.** `buildProject` hand-built argv so it could call `runBuild`, which meant a new required input on `upload` was an invisible runtime failure on the `debug open --upload-if-needed` path instead of a compile error. Split in two: `runBuild` parses argv into a `BuildRequest` and `executeBuild` runs one, so `buildProject` states what it wants and the compiler checks it. `connectToRuntime` lost its `ParsedArgs` for the same reason — it read exactly two things from it, credentials and `--create-user`, and both are structural inputs now. Credential resolution moved up to the argv layer but stays LAZY in effect: the outcome travels on the request (`credentials` or `credentialsProblem`) and is only reported on the branch that needs it, because a USB target needs no login at all. That ordering is why the resolution is allowed to have failed. **R5 — the protocol is specified.** `docs/CLI.md` gains the socket paths (unix socket, Windows named pipe), the NDJSON framing, every request kind with its fields and its answer, the response envelope, and the two properties a third client has to know: requests are answered one at a time in order, and a malformed line comes back with the id recovered from the raw text rather than leaving the caller to time out. Also corrects the `--create-user` row, which the previous commit documented as taking `user:pass` — it is a boolean, and the user it creates is the one already passed in `--credentials`. Validated on the P1AM-100 over serial (/dev/cu.usbmodem11301), reconnected for this round — compile, upload, `debug open --idle-timeout 0` (the value that was unreachable before B2), `list` reporting PLC state through the new probe path, read, force, watch+poll (21 samples, 8 transitions, zero decode failures on the 19-batch RTU profile), `exec` from a pipe, and SIGTERM on the daemon: it exited, unregistered, freed the port, and left `main:en_sinal` UNFORCED on the device. Exit codes on the serial target too: unknown target 3, bad `--idle-timeout` 2, upload with no port 2. 6884 tests pass, shared surface 0 diffs.

R5 and R19 closed as well, in R19 — the seam is a type. One ordering detail worth stating, since it is the reason the old code resolved lazily: credentials resolve in the argv layer but are only reported on the branch that needs them, because a USB target needs no login at all. The outcome rides on the request as R5 — the protocol is specified. Socket paths (unix socket / Windows named pipe), NDJSON framing, every request kind with its fields and its answer, the response envelope, and the two properties a third client actually has to know: requests are answered one at a time in order, and a malformed line comes back with the id recovered from the raw text instead of leaving the caller to time out. While writing it I found the previous commit had documented Validated on the P1AM-100, over serialYou reconnected it, so this round ran on hardware rather than on the runtime alone —
No stray processes and no SIGABRT after the serial sessions, and the registry came back clean. 6884 tests pass, shared surface 0 diffs over 1052 files, and the previous round's CI is green on both PRs including the packaged builds on all three OSes. That leaves nothing open from your review that I know of. The remaining items from it are the two you scoped out yourself: the |
`typeOf` returned the IEC type NAME alone, so both callers resolved an index's
metadata, threw everything but the type away, and looked the same index up again
in `emit` — and again in `onError`. Three map lookups per decoded position where
one will do, on every variable of every poll.
The worse half was what it did to the code around it. The second and third
lookups could not fail, since the walk only calls `emit` for a position `typeOf`
just resolved, but the compiler cannot know that — so both callers guarded them
with `if (!meta) return` branches annotated `istanbul ignore if`, four dead
branches whose only purpose was to satisfy the type checker about something the
walk had already proved.
`typeOf` now returns `{ type, meta }` and the walk hands `meta` to `emit` and
`onError`. `TMeta` is the caller's own — the GUI passes the leaves sharing that
address, the CLI passes its resolved variable — and the walker only ferries it.
All four guards are gone, and the type parameter made the compiler point at both
call sites the moment the signature changed, which is the check that matters
here: the walk pairs bytes with variables positionally, and metadata arriving
from the wrong position would write a decoded value onto the wrong variable
without erroring.
Pinned by a test asserting each callback receives the metadata resolved for THAT
position, not merely some metadata. `onError`'s half is one line above in the
same resolution and is not pinned: nothing in this codec throws on demand — the
only type that does under jest is `STRING`, and only because jsdom has no
`TextDecoder`, so a test asserting on it would be testing the environment. That
`catch` was already uncovered before this change; coverage is unmoved.
Hardware-validated on both transports, since a silent mis-pairing is the failure
mode here. SLM-RP4 over websocket and P1AM-100 over serial: all 14 variables read
back, zero undecodable, including the duplicate paths that share one index —
which is the multi-leaf case `meta` now carries. Watch/poll on both: 28 and 21
samples, zero decode failures, 8 blink transitions each, and every TIME sample
reading 500ms rather than drifting.
Shared surface: 0 diffs over 1052 files.

Description of the changes proposed
Adds
openplc— a headless CLI exposing the editor's operations for automated testing:devices,compile,upload, and a session-baseddebug.The design rule: each command triggers the same orchestrated flow its GUI control triggers. Not a reimplementation.
compilecompileProgramFlowuploadcompileProgramFlow(+ host/port)devicesdiscoverRuntimes+getAvailableSerialPortsdebug start/stopRuntimeApiClient.setPlcState(REST) or FC 0x4b (channel)debug read/watchwalkDebugResponsedebug forceencodeForceValueHolding that rule required extracting four things so both front ends share one implementation, rather than letting the CLI carry a copy:
compileProgramFlow— the orchestration behindCompilerPort.compileProgram(board resolution, library C++ graft, POU preprocessing, pipeline arguments), now driven by a three-call transport. The renderer supplies awindow.bridgetransport; the CLI supplies one over the main-process modules.RuntimeApiClient(backend/editor/runtime/) — the runtime REST layer lifted out ofMainProcessBridge, which now delegates.debug-channel-factory—toDebugCandidate/toDeviceLinkCandidateslifted out of the bridge, so every declared transport (Modbus RTU, Modbus TCP, the v4 WebSocket, the in-process simulator) is built from the board's declarative spec.discoverRuntimesandwalkDebugResponse— the UDP scan and thegetVariablesListwalk, each previously single-caller.Debug is session-first.
debug openforks a daemon holding the channel and returns asession_id; one-shot commands dial its socket; the REPL anddebug execare clients of the same NDJSON protocol. That shape exists because a debug session is long-lived while a test step is one process: prompt-scraping an interactive REPL is the flaky-test tarpit.closereleases the session's forces by default, since the runtime clears them only on program unload/stop and cannot notice a debugger leaving.Three bugs fixed on the way
uploadRuntimeV4, which the compile-only branch returns before.build/<target>/held 17 files instead of 51 — missingprogram.st, the generated C++,defines.handdebug-map.json. It hid because any earlier upload leaves a complete folder behind, so it only shows on a clean build. This also fixes the editor's Build → compile-only.ModbusRtuClient.disconnect()closed the port fire-and-forget;@serialport/bindings-cppreleases the handle asynchronously and its NAPI cleanup hook throws if the environment tears down mid-close.

Review round 2 — every issue fixed, and what testing found afterwards
Merged
developmentin. One conflict, inmain.ts'stoDebugCandidate, and itwas semantic rather than textual: this branch had extracted that method into
debug-channel-factory(shared with the CLI) from a copy taken before #1023,while
developmenthad meanwhile changed the same lines to read the runtime tokenat channel-open time. Resolved by keeping the extraction and giving the factory a
getTokenseam, so #1023's behaviour is preserved rather than reverted. All fiveof its pieces verified present after the merge:
isLicenseChannel, theLicenseChanneltype,reauth?.(newToken),debugHolderSeq'swhat#seqholdersuffix, and
withLicenseChannel.R17 (the positional compile-args contract). The 10-element array was declared
with a different element union at all four hops —
Array<string | PLCProjectData>in the IPC handler,Array<string | boolean | null | PLCProjectData | Record<string, unknown>>in the renderer bridge, andArray<string | null | boolean | undefined | object>in both the flow and thecompiler module. None of them agreed, which is exactly why handing the list from
one hop to the next needed
as never. There is now one labelled tuple,CompileProgramIpcArgs, declared once and imported by the flow, the adapter, therenderer bridge and the handler: a slot in the wrong place is a compile error
instead of a corrupt build, and both casts are gone rather than justified.
Defects the platform testing turned up
Testing after the merge found six real bugs, four of which no test could have
caught because they only appear on a machine that is not a developer's:
openplc-cli --help 2>&1 | head -3neverreturned.
headleaves, the pipe closes, the next write raises EPIPE — and thereporter's attempt to report that raises EPIPE too, so
main()rejected,void main()swallowed it, and an Electron main process with no window simplyidles. In a pipeline that is not a failed step; it is a job that burns its
timeout and reports nothing. Guards now make every path exit.
getTokenseam, but the factory's websocket branch never consulted it — thebehaviour was reverted while looking preserved. A channel opened after a
transparent re-login presented a stale JWT, and the runtime re-verifies on every
command, so the session and the licensing PDUs sharing that socket die on the
first one. Now read through the seam at open time, and pinned by tests, because
nothing observable breaks when this regresses — which is why it did.
openplc-cli devices | jqbroke in acontainer: Winston's console transport sends everything not named in
stderrLevelsto stdout, and nothing was named. Two coloured log lines cameout wrapped around otherwise-valid JSON. Every level goes to stderr now.
--helpshelled out toarduino-cli, twice, and died when it was missing.UserService's constructor starts its scaffolding andinitialize()started itagain — four processes to answer
--help, every warning printed twice. Then therun itself was fatal: promisified
execrejects when the binary is absent, sothe awaited call took the process down with exit 70 for commands that never
compile anything. One run now, its two shell-out steps tolerated with a warning
(which is what the GUI already did by accident), and a meta-only invocation
skips the scaffolding entirely.
install-clion Linux generated a shim with no script in it. The Linuxre-exec puts the headless Chromium switches ahead of everything else, so
process.argv[1]— where this looked for the bundle — was--no-sandbox, and theemitted shim was
electron --cli "$@". Electron handed no script hangs ratherthan erroring; the code even warned about that failure mode two lines above the
bug. Found by shape now, not by position.
readwas an unknown command insidedebug exec. The REPL mirrorsstrucpp'sverbs (
vars/get/set) while the subcommands arelist-vars/read/write.One operation, two vocabularies, and a caller who learned the subcommand got
"Unknown command" the first time it typed the same word into
exec. Bothspellings now parse to the same protocol request.
Also fixed: the dev bundle entered at
cli/main.tswhile the packaged binaryenters at
main/entry.ts, so the dispatcher's Linux re-exec and its load-failurehandling were untestable with the bundle used to test everything else. The dev
entry is now the shipped one.

A broken native module still hangs on Windows. The UMD wrapper that this
bundle and the shipped
main.jscarry requiresserialportandsocket.io-clientin its factory call, before any of our code runs, so noJS-level guard can precede it — Electron's modal "App threw an error during
load" dialog is what you get. Reaching it needs a broken installation. The fix is
dropping the pointless UMD wrapper from the main bundle (nothing imports it as a
library), which is a packaging change deserving its own PR and a package build
per platform. Related:
@serialport/bindings-cppships nowin32-arm64prebuild, so a Windows-on-ARM package would hit exactly this.
