For the archi-dev-box agent: companion 0.5.28 is on main (PR #149) and
Gitea raw serves it (verified byte-identical, v1+v2+v3). Remaining: the
foundation server's static /packages mirror (the real-node QR download
URL — currently 0.5.27), node web-bundle redeploys (same as the
2026-07-23 flow), and confirming the demo stack flipped after CI's
webhook redeploy. Exact commands, expected shasum, and final verify
block included.
