Summary

Build #104 (the WinPE-collector merge) failed at Stage 6 oscdimg: Insufficient disk space ... need 5319557120 bytes. The collector work added WinPE-NetFx/PowerShell to boot.wim (image grew ~0.4 GB → 5.32 GB), and each successful build persists a ~5 GB ISO to C:\silvermetal\out\. On the single-volume runner (no usable D:/E:) that accumulation starves oscdimg.

Fix

Add a "Free disk space" step at the start of the build job that clears the prior ISO output (C:\silvermetal\out\*) and any stale smbuild work dir before building, logging before/after free space. Space now self-heals every run.

(I also manually deleted the stale 4.94 GB ISO on the runner so this build has headroom; this step makes it durable.)

Test Plan

YAML validates (yaml.safe_load)
Build goes green through oscdimg + the new boot.wim collector assertions, persists the ISO

ci(windows): free disk space before build (clear prior ISO output)

Build SilverMetal Enhanced - Windows ISO / build (pull_request) Failing after 21s

Details

The boot.wim now carries WinPE-NetFx/PowerShell (collector), growing the image ~0.4GB,
and each build persists a ~5GB ISO to C:\silvermetal\out. On the single-volume runner
that accumulation starved oscdimg ('Insufficient disk space'). Clear prior output +
stale smbuild work dirs at job start so free space self-heals each run.
