- 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.
Spike outcome: the shared ILdapAuthService (ZB.MOM.WW.Auth.Abstractions, an external
NuGet package) exposes ONLY AuthenticateAsync(username, password, ct) — no passwordless
service-account group-search. A live LDAP group re-query for an active session therefore
requires a new lib method and is OUT OF SCOPE (cannot modify the external package).
Implemented the always-achievable layers (cookie-only; no embedded JWT for cookie principals):
- /auth/login now stores the user's raw LDAP groups (one zb:group claim each) plus a
zb:lastrolerefresh anchor (login time, UTC), seeding the LastActivity idle anchor too.
- SessionClaimBuilder: single shared DRY claim-builder used by BOTH /auth/login AND the
refresh path, so the two claim shapes cannot drift (canonical identity/role/scope claims
with nameType/roleType pinned, plus the M2.19 group + refresh-anchor additions).
- CookieSessionValidator (TimeProvider-injected, unit-testable) + a thin
CookieAuthenticationEvents.OnValidatePrincipal adapter:
* idle-timeout: a session past IdleTimeoutMinutes (default 30) is RejectPrincipal+SignOut;
consistent with the cookie ExpireTimeSpan+SlidingExpiration window (same value).
* role refresh WITHOUT LDAP: when older than RoleRefreshThresholdMinutes (new option,
default 15) the DB-backed RoleMapper re-runs on the STORED groups, claims are rebuilt
via the shared builder, the anchor advances, principal is replaced + cookie renewed.
Revoked DB mappings drop the user's roles mid-session.
* fail-soft: any refresh error KEEPS the existing principal (no sign-out, never throws)
— mirrors the documented "LDAP failure: active sessions continue with current roles".
- Documented residual limitation in Component-Security.md: central role-mapping/scope
changes apply within ~15 min without LDAP; live directory group-membership changes are
picked up only at next login (needs a passwordless group-search on the external
ZB.MOM.WW.Auth.Ldap lib — tracked follow-up).
Tests (Security.Tests, all green): CookieSessionValidatorTests + SessionClaimBuilderParityTests
— idle reject/keep, LDAP-free remap-from-stored-groups, revoked-roles loss, sub-threshold
no-refresh, refresh-throws-keeps-session, and login/refresh claim-parity.
Resolve all 622 issues flagged by the enhanced CommentChecker: add missing

add missing <summary> tags, and replace misused/redundant <inheritdoc/> on
members that override or implement nothing with real documentation.
Documentation-only — no behavior change; solution builds clean.
