 # Maintainer note: this E2E test requires a reachable MemoryHub instance.
-# Add the following repository secrets so CI runs the test:
-#   MEMORYHUB_E2E_URL              (required) — public MemoryHub MCP URL
-#   MEMORYHUB_E2E_API_KEY          (one of)  — static API key
-#   MEMORYHUB_E2E_AUTH_URL         (or…)
+#
+# URL resolution order:
+#   1. MEMORYHUB_E2E_URL env var / repo secret (explicit override)
+#   2. MemoryHub discovery endpoint (auto-detects current sandbox URL)
+#
+# Credentials (at least one set required):
+#   MEMORYHUB_E2E_API_KEY              — static API key
+#   MEMORYHUB_E2E_AUTH_URL             — OAuth 2.1 credentials (all three)
 #   MEMORYHUB_E2E_CLIENT_ID
-#   MEMORYHUB_E2E_CLIENT_SECRET    — OAuth 2.1 credentials
+#   MEMORYHUB_E2E_CLIENT_SECRET
+#
 # When neither credential set is configured the test skips cleanly so
 # contributor forks don't fail on a missing secret.
