## Description Windows `persistent-task` created its startup and 5-minute health tasks via `schtasks` command-line flags, which register the task with an **interactive-token** principal. Every task run spawned a visible console window that briefly grabbed keyboard focus before vanishing — every 5 minutes, indefinitely (and at boot / proxy restart). Fixes #2453. This registers the tasks from Task Scheduler **XML** instead: user-scope tasks use an **S4U** principal (run whether the user is logged on or not, no stored password) with `<Hidden>true</Hidden>`, so runs execute in a non-interactive session and never draw a window. System-scope tasks keep the LocalSystem service account (which already has no desktop). ## Type of Change - [x] Bug fix (non-breaking change which fixes an issue) ## Changes Made - `headroom/install/supervisors.py`: add `_windows_task_xml()` (S4U/hidden for user scope, LocalSystem for system scope), `_windows_boot_trigger()`, `_windows_health_trigger()` (PT5M repetition), and `_register_windows_task()` (writes UTF-16 XML to a temp file and calls `schtasks /Create /TN <n> /XML <file> /F`). Rewrite the Windows TASK branch of `install_supervisor` to register both tasks from XML. - `tests/test_install/test_supervisors.py`: unit tests asserting the XML carries `S4U` + `Hidden` + `PT5M` for user scope and `S-1-5-18` / `ServiceAccount` for system scope; updated the install-flow assertion to expect `schtasks /XML` registration for the startup and health tasks. ## Testing - [x] Unit tests pass ``` $ python -m pytest tests/test_install/test_supervisors.py -q collected 29 items tests\test_install\test_supervisors.py ............................. [100%] ============================= 29 passed in 1.48s ============================== ``` ## Real Behavior Proof - Environment: Windows 11 Pro 10.0.26200, Python 3.13.11 - Exact command / steps: python -m pytest tests/test_install/test_supervisors.py -q; ruff check + ruff format --check; mypy headroom/install/supervisors.py --ignore-missing-imports - Observed result: 29 passed; ruff clean; mypy exit 0. Generated XML contains <LogonType>S4U</LogonType> and <Hidden>true</Hidden> for user scope. - Not tested: live end-to-end `headroom install apply --preset persistent-task` on a physical desktop confirming zero console flash over a >5-minute window (no interactive Windows session in CI). ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> |
