v2-ci / unit-tests (push) Has been cancelled
ConfigurationBinder appends configured collection items to an existing list, so the pre-filled [None, Sign, SignAndEncrypt] default made "drop None" a no-op: every deployment that listed only the secure profiles still advertised an unsigned/unencrypted None endpoint. EnabledSecurityProfiles is now null by default; ResolveEnabledSecurityProfiles() applies the unchanged three-profile default only when nothing is configured. A set-but-empty list fails startup validation and BuildSecurityPolicies no longer falls back to a None endpoint on empty input (it throws). Sweep of all options classes found no other non-empty pre-filled collection default. Tests: options binding (indexed, JSON, env forms, default, empty, bad name), a booted-server wire test (no None endpoint, None connection refused with BadSecurityPolicyRejected, secure connection works; default case is the control).
