β¦#3160) Installed supervisor units restarted the gateway unconditionally, so the runtime's fatal-config exit (78, EX_CONFIG) was discarded and a broken config crash-looped forever. Map the existing core exit-code contract to per-OS restart directives: - systemd: Restart=on-failure + RestartPreventExitStatus=78 + StartLimitBurst=5 (bounded restarts). - launchd: KeepAlive dict (SuccessfulExit=false, Crashed=true) + ThrottleInterval so a clean/fatal exit is not relaunched every few seconds. - windows: wrap the scheduled task / startup script so exit 78 maps to a clean stop instead of a relaunch.

The generated unit runs gateway start, whose command handler discards the status returned by GatewayHandler.start(). A transient failure classified as exit 75 therefore reaches systemd as exit 0, and this changed Restart=on-failure policy leaves the daemon stopped instead of restarting it.

Scheduled task now points at the generated .cmd wrapper (single, well-formed quoting) instead of the fragile inline cmd /c "<python> β¦ & if %ERRORLEVEL% β¦" string that nested quotes and misparsed paths under C:\Program Files. Wrapper already owns exit-78 translation; uninstall already removes it. (Greptile P1) |

+2 tests: praisonai_bot gateway start propagates fatal (78) and clean (0). |

+1 test: Windows task command is the wrapper path (no cmd /c, no %ERRORLEVEL% nesting), wrapper written + owns exit-78. |
Tests: 19/19 pass (11 exit-code incl. 2 new + 8 daemon-generation incl. new Windows test). Remaining failures in the suite are unrelated env gaps (missing pytest-asyncio/other packages).
Reviewed but intentionally not changed
- Greptile P1 "launchd fatal restarts unbounded" β acknowledged limitation, not fixed. launchd has no exit-code-specific stop (unlike systemd/Windows). A truly bounded fatal-stop would need a persistent on-disk restart guard (the in-memory
RestartLoopGuardresets each process). That's meaningful new surface area / scope creep for a wrapper-only fix. Current mitigation (ThrottleInterval=30bounding to ~1 relaunch/30s + the runtime guard) is the pragmatic ceiling and is already documented in the plist comment. Flagging as a known trade-off rather than expanding scope.
Verdict β β Approve (with the launchd caveat noted)
Now that the exit code actually reaches the supervisor, the systemd RestartPreventExitStatus=78 and Windows exit-78 mapping deliver the fix's intent. Change is protocol-driven (reuses the existing core GATEWAY_FATAL_CONFIG_EXIT_CODE contract), wrapper-only, backward-compatible, no Agent-class bloat, no new deps. The launchd path is best-effort by OS constraint.
Scope: only Python praisonai-bot wrapper touched; no praisonaiagents core, praisonai-rust, or praisonai-ts changes.

Windows cmd /c %ERRORLEVEL% expansion before command execution delayed expansion errorlevel documentation
π‘ Result:
In the Windows Command Processor (cmd.exe), environment variables like %ERRORLEVEL% are expanded at the time the command line or block is read (parsed), not when it is executed [1][2]. When using cmd /c, the entire command string provided is parsed in a single pass [3]. Consequently, if you use %ERRORLEVEL% in a sequence of commands, it will expand to the value that existed before the current command line began execution, not the value produced by any preceding command in that same line [4][3]. To obtain the exit code produced by a command within the same line, you must delay the expansion of the variable until execution time [1][3]. There are two primary methods to achieve this: 1. Use Delayed Expansion: Enable delayed expansion by starting the cmd instance with the /V:ON switch [3][5][6]. Once enabled, use the exclamation point syntax (!ERRORLEVEL!) instead of percent signs [1][3][5]. Example: cmd /V:ON /C "my_command && echo!ERRORLEVEL!" [3][7] 2. Use the CALL command: The CALL command forces a second round of parsing on the provided string [3]. By escaping the percent sign (using a caret ^), you can prevent the first parse from expanding the variable, allowing CALL to evaluate it during the second parse after the preceding command has executed [3][7]. Example: cmd /C "my_command && call echo %^ERRORLEVEL%" [3][7] Note that %ERRORLEVEL% is a dynamic pseudo-environment variable [8][9]. It is maintained by cmd.exe to reflect the exit code of the most recently executed command [10][9]. While it behaves like a standard environment variable, it is technically a fallback mechanism; if a user manually creates an environment variable named ERRORLEVEL, that user variable will take precedence and hide the dynamic value [11][9]. Therefore, it is best practice to avoid manually setting an environment variable named ERRORLEVEL [10]. Furthermore, because %ERRORLEVEL% is an internal value, conditional execution operators like && and || are often more robust alternatives than checking the variable, as they do not rely on variable expansion at all [10].

Fix the Windows cmd exit-code check
%ERRORLEVEL% is expanded when cmd /c parses the line, so this can read the value from before the gateway runs. Switch to delayed expansion (cmd /V:ON /C "... & if !ERRORLEVEL! EQU 78 exit /b 0") or use if errorlevel 78 if not errorlevel 79 exit /b 0 so fatal-config exits stop the task instead of crash-looping.

β¦arden Windows task quoting (#3160) The installed daemons run python -m praisonai_bot gateway start, whose Typer command discarded GatewayHandler.start()'s int return. Typer ignores a returned int, so the process always exited 0 - the generated units' Restart=on-failure / RestartPreventExitStatus=78 / KeepAlive.SuccessfulExit directives never saw the real fatal-config (78) / transient (75) code, making the whole feature inert. Surface it via typer.Exit. Also replace the Windows scheduled-task's fragile inline cmd /c string (nested quotes that misparse paths under C:\Program Files) with a single quoted path to the generated .cmd wrapper, which already owns the exit-78 translation.

The pre-existing test_windows_scheduled_task_command_is_well_formed asserted `--config` appeared inline in the /TR value. This PR intentionally routes the scheduled task at the generated .cmd wrapper (single, well-formed quoting) to avoid the nested-quote hazard for paths with spaces, so /TR now points at the wrapper path and the wrapper owns the --config invocation.
