- Add SecurityOptionsValidator (IValidateOptions<SecurityOptions>) enforcing
RoleRefreshThresholdMinutes < IdleTimeoutMinutes; registered with ValidateOnStart in
AddSecurity — startup FAILS if threshold >= idle, so the invariant cannot be silently
misconfigured away.
- Update SecurityOptions XML-docs: class-level summary distinguishes JWT Bearer path
(JwtSigningKey/JwtExpiryMinutes) from Blazor cookie session path (IdleTimeoutMinutes/
RoleRefreshThresholdMinutes); both time fields document the ~45-min effective idle window
and the new cross-field constraint.
- Remove dead jwtService variable from /auth/login lambda in AuthEndpoints.cs (resolved
but never used since login moved to SessionClaimBuilder).
- Extract ApplyValidationResultAsync helper from OnValidatePrincipalAsync (pure
decision-application step); add 3 adapter tests covering Reject → RejectPrincipal +
SignOutAsync; Replace → ReplacePrincipal + ShouldRenew; Keep → no-op.
- Fix inaccurate TryRefreshAsync comment (dropped "OR last-activity needs advancing" —
the code only returns non-null when roleRefreshDue).
- Add InternalsVisibleTo for Security.Tests in Security.csproj.
- Add IsRoleRefreshDue tests: missing claim → due; unparsable claim → due; plus integration
test covering the full ValidateAsync path for a principal missing zb:lastrolerefresh
(triggers refresh + re-stamps anchor rather than keeping stale principal forever).
- Add SecurityOptionsValidatorConfigGuardTests: default succeeds; equal fails; greater fails;
boundary (idle-1) succeeds; wiring confirmed via AddSecurity container.
