# Compatibility matrix

The checkboxes distinguish automated coverage from physical verification. A stable
release requires every physical row to be exercised on real hardware.

| Environment | Automated | Physically verified | Result |
|---|---:|---:|---|
| Top horizontal bar | yes | yes | passing |
| Bottom horizontal bar | yes | yes | passing |
| Vertical bar | yes | yes | intentionally dormant |
| Bar hide and restore | yes | yes | passing |
| Fullscreen application | structural | yes | passing |
| Single monitor, 1× scale | yes | yes | passing |
| Two monitors, same scale | geometry + handoff | no | pending |
| Two monitors, mixed scale | geometry + handoff | no | pending |
| Fractional display scale | geometry model | no | pending |
| Ultrawide display | geometry model | no | pending |
| Bar heights 24–48 px | geometry + asset bounds | no | pending |

Physical checks must cover focused-monitor handoff, click masks, Journal/Care
anchoring to the active sprite, Curious cursor bar-band sensing (when enabled),
clock-passage geometry, fullscreen stacking, and absence of apparent sprite-scale
changes. Record hardware, scale, bar position, and result in the beta report.

Automated geometry coverage is provided by `tools/validate-geometry.py` and the
IPC `pose` response, which reports logical monitor size, display scale, bar size,
resident status, and the active sprite bounds. The model deliberately keeps
logical lane coordinates stable across fractional display scales.
