README

QCU — Quick Computer Use

**1.8.** QCU controls an explicitly selected browser page or desktop window with accessibility references. This revision binds references to a backend lifetime, target and observation; separates dispatch from verified results; and adds a minimal Windows UI Automation backend. **Windows 真机未验证.**

Install

Python 3.11+:

python -m pip install -e '.[dev]'        # web / development
python -m playwright install chromium   # web only
python -m pip install -e '.[macos,dev]'  # macOS AX

On Windows PowerShell:

py -m pip install -e ".[windows,dev]"
py scripts/verify_windows_uia.py

Platform extras use environment markers. Web/macOS installations do not import or install Windows UIA dependencies. See [INSTALL.md](INSTALL.md).

Target → observe → act → verify

qcu session start --context desktop
qcu observe --pid 12345 --window 'Fixture window' --compact
# Copy opaque refs from this observation. Example placeholder:
qcu act '{"type":"click","params":{"ref":"","verify":{"kind":"text","equals":"Saved 1"}}}'
qcu session end

For web use `session start --context web`, navigate, then observe. QCU Chromium has its own profile; it does not inherit the user's open authenticated tab. Preserve the selected target. Tests must use an independent `QCU_HOME`.

Explicit missing or ambiguous windows fail with diagnostics/candidates.
routing_meta.target identifies the app/window or browser tab.
Re-observe after a backend restart, target change or invalid reference. Old numeric and obs_N:ref_M tokens are not upgraded into new control identities.
Ref actions never become cached-coordinate actions. Coordinate/OCR paths must establish the same target; unavailable inspection stops them.
A successful call or changed interface is distinct from the requested result. Only outcome: verified confirms the specified postcondition.
batch permits 1–32 actions, fills before one final action, a
