+# AI Modification Log: Z Workflow Debug Noise
+
+Date: 2026-06-29
+
+## Change
+
+- Removed Z-only debug output from `.github/workflows/X-x86_64_Z.yml`:
+  - `docker images`
+  - `ls bin/Firmware`
+  - `ls openwrt/bin/Firmware`
+
+## Reason
+
+These commands were useful during debugging but do not affect build artifacts. Removing them reduces log noise and keeps the Z workflow closer to X/Y behavior.
