-# Probe-only workflow — answers all runner unknowns before real CI is designed.
-# Runs ONLY on the feature branch; never on main.
-# All steps that may fail on this runner use continue-on-error: true or || true
-# so the probe REPORTS findings instead of red-failing on an expected unknown.
-# Do NOT reference any secret in this workflow (T-08-01).
-#
-# Checks performed: P-01 through P-11 + P-13
-# P-12 (docker login) is deferred to Plan 04 (publish) — DO NOT add it here.
-
-# Probe served its purpose (run #2 recorded the fork answers in 08-01-SUMMARY).
-# Switched to manual-only so it no longer re-runs on every push and competes
-# with ci.yml on the single runner. Throwaway — remove before merge to main.
