+
+## Protected behavior
+
+Pending, locked, deactivated, non-Intern, not-started, completed, and date-expired records must not appear in the
+Account-owned Intern picker. An option is selectable only when both account and internship are ACTIVE and the
+explicit business date lies within the inclusive internship range. The returned numeric user ID is the internal
+submission identity, and options sort by display name then student code.
+The public query rejects a missing business date with the documented actionable message instead of issuing an
+ambiguous null-bound database query.
+
+## Test method
+
+The PostgreSQL 18.4 integration test persists valid account/profile combinations through the account feature's JPA
+entities and repositories. It uses SQL only as a test fixture for future lock, deactivation, and completion states
+whose production transitions are outside this change. It calls the public Account service query and compares the
+complete immutable DTO sequence, including both inclusive date boundaries and unique user IDs.
+Its separate null-date regression calls the same public service method and asserts the exact
+<code>IllegalArgumentException</code> message documented by that method.
+
+## Hand-derived expected result
+
+For business date 2026-08-14, profiles starting on that date and ending on that date remain eligible. The only
+expected options are Alpha / STU-100, Alpha / STU-200, and Zeta / STU-300, in that order. Every other seeded
+row fails at least one account role/state, internship state, or inclusive date condition.
+For a missing business date, the service must immediately throw
+<code>IllegalArgumentException("Business date is required")</code>.

 ## Protected behavior
 
 Targeted repairs use the realizable `work/fix/<feature>/<what-fix>` branch and
 clean worktree from taskmaster-verified `main`. Contributor guidance must reject
 the impossible `work/<feature>/fix/<what-fix>` form while persistent
-`work/<feature>` refs exist.
+`work/<feature>` refs exist. The tracked copies of root coordination authority
+must use the same rule. Every targeted-fix guide must also require the complete
+lifecycle: latest `main`, TDD RED → GREEN, Javadoc during implementation,
+companion evidence, independent review, and an authorized normal, non-force
+merge.
 
 ## Test method
 
 Use the tracked Node validator rather than an artificial Java test. It requires
-the exact approved statement in each of the six guides, then self-tests that an
+the exact approved branch statement and complete targeted-repair lifecycle in
-extra positive nested-branch recommendation is rejected. The original RED

+lifecycle elements from every guide and asserts the file-specific rejection. It

+and checked for their exact approved rules. The original RED proves the
+required branch name was absent from the four contributor guides; the first
+review-fix RED proves the executable regression was absent.
 
 ## Hand-derived expected result
 
 The required fix-branch spelling appears exactly once in each of the six tracked
 documentation artifacts, and the only nested-form reference is inside that

+
+## Incident scope
+
+This record covers only the reported HTTP 403 for a fresh Admin session on
+`GET /attendance/calendar`. The separately supplied 500 about policy
+materialization is not a calendar-session or identity-mapping claim. It is
+cross-referenced to
+`.superpowers/sdd/access-navigation-icon-intern-picker/task-4-intern-dashboard-report.md`,
+which independently records valid current PostgreSQL policy/constraint state
+and no reproduction of that 500.
+
+## Protected behavior
+
+The persisted first Admin can open global calendar management after a real CSRF-protected form login. Persisted Mentor and Intern accounts, each authenticated by the same form-login path, receive HTTP 403 for that route.
+
+## Test method
+
+The test posts the actual bootstrap form, logs in through Spring Security, and follows the resulting session to `/attendance/calendar`. It configures a test-only SMTP probe solely to activate Mentor and Intern accounts through the public AccountService, then logs in those accounts before asserting denial. Spring Boot applies Flyway to PostgreSQL 18.4 through the shared Testcontainers configuration.
+
+## Hand-derived expected result
+
+The bootstrap entity always has immutable `ADMIN` role, so its fresh authenticated session must receive HTTP 200 from the Admin-only calendar route. Immutable `MENTOR` and `INTERN` roles are not permitted by `CAL-001`, so their matching fresh authenticated sessions must receive HTTP 403. No calendar mutation is attempted.

+# Test Evidence: persistent Admin SMTP settings navigation
+
+- **Test type:** Web
+- **Requirement IDs:** `ACC-007`, `INT-001`, `AUTH-002`, `UI-003`, `UI-008`, `UI-009`, `UI-010`
+- **Scenario IDs:** `AC-ACC-003`, `AC-UI-002`, `AC-UI-003`
+- **Test class/method:** `com.lab.labtimesheet.feature.reporting.controller.DashboardControllerWebTest`, `com.lab.labtimesheet.feature.reporting.controller.RoleDashboardWebIntegrationTest#mentorAndInternDashboardsRenderRealScopedProjectTaskAndAttendanceData`
+- **Implementation commit:** pending
+
+## Protected behavior
+
+An Admin always receives an SMTP settings destination in the shared sidebar, whether SMTP is restricted or active. The restricted-installation warning remains conditional. Mentor and Intern sidebars never expose the Admin-only destination, and the Admin link uses the local settings sprite plus the established collapsed-sidebar tooltip.
+
+## Test method
+
+The MVC slice renders the real dashboard controller, Spring Security Thymeleaf dialect, and shared layout with only the SMTP state and dashboard query services mocked at their public boundaries. It checks both Admin SMTP states and the active-SMTP Mentor/Intern views. The PostgreSQL 18.4 integration test activates SMTP through the real service, extracts rendered navigation links, requires the Admin SMTP route only for Admin, and follows every discovered link through the real controller/security stack.
+
+## Hand-derived expected result
+
+With SMTP restricted, an Admin dashboard contains the existing warning and a sidebar link to `/admin/smtp` identified by `data-tooltip="SMTP settings"`. After SMTP activation, the warning is absent but that same sidebar link remains. Mentor and Intern dashboards omit the SMTP-settings tooltip and route. The activated Admin link resolves successfully when followed.

+MockMvc proves rendered role/state visibility, while the PostgreSQL integration test proves the real Admin route follow. They do not render the collapsed rail or inspect pixels, browser focus placement, or tooltip positioning; the existing CSS and local settings sprite are reused unchanged. Server-side direct-URL authorization remains the existing `/admin/**` Admin-only security rule and is not broadened by this layout-only change.
