- Replace fragile `git fetch --depth=1 origin "$SHA"` (fails with short SHAs) with `git clone --no-checkout --filter=blob:none` + `git checkout "$SHA"` across all 3 Argo templates (5 clone blocks total) - Upgrade CI compile pool from POP2-32C-128G to POP2-HC-32C-64G (higher clock EPYC cores, 28% cheaper at €0.851/hr vs €1.18/hr) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
