test.stackalchemist.app down: Cloudflare 1033 (tunnel connector gone), no successful test deploy since May

[stevenfackley]

Problem

https://test.stackalchemist.app returns Cloudflare error 1033 (Argo Tunnel — no healthy sa-test-tunnel connector). Every deploy-test.yml run since 2026-05-07 ended cancelled (all "merge main into develop" pushes), so the test stack has been rotting for ~2 months.

Evidence

• curl https://test.stackalchemist.app/ → HTTP 530, error code: 1033 (2026-07-11)
• gh run list --workflow deploy-test.yml → 8 most recent runs all completed/cancelled, newest 2026-06-01

Fix (on the prod box)

1. Check/restart the standalone sa-test-tunnel container (it must survive deploys, same pattern as sa-tunnel)
2. Figure out why every deploy-test run gets cancelled (concurrency group? develop-branch push pattern?) and get one green run through
3. Consider a test-site healthwatch like prod's — nothing noticed this for two months
