+name: Canary — staging SaaS smoke (every 30 min)
+
+# Minimum viable health check: provisions one Hermes workspace on a fresh
+# staging org, sends one A2A message, verifies PONG, tears down. ~8 min
+# wall clock. Pages on failure by opening a GitHub issue; auto-closes the
+# issue on the next green run.
+#
+# The full-SaaS workflow (e2e-staging-saas.yml) covers the broader surface
+# but runs only on provisioning-critical pushes + nightly — this one
+# catches drift in the 30-min window between those runs (AMI health, CF
+# cert rotation, WorkOS session stability, etc.).
+#
+# Lean mode: E2E_MODE=canary skips the child workspace + HMA memory +
+# peers/activity checks. One parent workspace + one A2A turn is enough
+# to signal "SaaS stack end-to-end is alive."
