Fixes the Niri window rule in the README so it no longer produces errors. Replaces the invalid default-floating-size option with default-column-width and default-window-height.
Confidence Score: 5/5
No blocking issue identified; the README change is safe to merge.
What we checked:
I observed that the previous default-floating-size rule failed validation (exit 1).
I confirmed that the updated rule passed (exit 0) after the change.
I consulted Niri’s v26.04 documentation and noted that default-column-width also applies to floating windows and shows fixed dimensions with open-floating as opening properties.
I interpreted this to mean the 500×430 initial configure request is supported as an opening property, not a universal guarantee for all clients.
Artifacts capturing the validation script and log outputs were prepared to support reviewer inspection.
Summary
The README replaces an invalid Niri floating-size directive with separate width and height rules for the intended 500×430 launcher size. The updated rule passed Niri 26.04 configuration validation. No actionable issue was found.
