+# Lab Timesheet — Three-Iteration Delivery Plan
+
+**Artifact purpose:** Local agent coordination and progress tracking  
+**Implementation branches:** `work/platform`, `work/projects`, `work/tasks`, `work/attendance`, `work/reports-ui`  
+**Requirements authority:** `labtimesheet-docs-hub/requirements-specification.md`  
+**SRS:** `labtimesheet-docs-hub/software-requirements-specification.md`  
+**Initial status:** Planning complete; implementation remains subject to requirements approval
+
+This file divides the approved product scope across three iterations and five persistent work branches. It is a coordination artifact, not an alternative requirements source. When this plan and a numbered requirement disagree, the numbered requirement wins.
+
+## 1. Progress rules
+
+Use these exact status values:
+
+| Status | Meaning |
+|---|---|
+| `TODO` | No implementation work has started. |
+| `IN_PROGRESS` | One named owner is actively working on the item. |
+| `BLOCKED` | Work cannot continue; the tracker must name the evidence and required decision/dependency. |
+| `DONE` | Required RED/GREEN evidence exists, affected tests pass, and the integrated behavior satisfies the requirement. |
+
+Before editing production code, an agent shall:
+
+1. Read the applicable numbered requirements and acceptance scenarios.
+2. Claim one bounded tracker item by setting its status to `IN_PROGRESS` and recording owner/date.
+3. Identify the test level and evidence file that will protect the behavior.
+4. Write and run the failing test before production code.
+5. Confirm the test fails because the required behavior is missing, not because the test or environment is broken.
+
+When completing an item, the agent shall record:
+
+- the exact RED command and expected failure;
+- the exact GREEN and affected-suite commands;
+- the evidence Markdown path under `docs/tests/`;
+- the implementation commit or final local commit SHA;
+- any remaining limitation that is explicitly allowed by the requirements.
+
+No item becomes `DONE` based only on compilation, an isolated happy path, screenshots, or a verbal claim.
+
+## 2. Branch ownership and conflict boundaries
+
+| Branch | Sole or primary ownership |
+|---|---|
+| `work/platform` | Maven/application baseline, feature-package foundation, Flyway migration files, account/security/bootstrap, internship lifecycle, integration credential lifecycle, notification delivery infrastructure, Docker, and CI. |
+| `work/projects` | Projects, membership intervals, invitations, membership-exit requests, leadership terms, Project lifecycle, Project-scoped authorization, member-removal orchestration, and Project completion. |
+| `work/tasks` | Tasks, generic creator/assignment actors, member self-Task rules, comments, work logs, fixed status transitions, assignment/reassignment, Task soft deletion, and Project Task-progress calculations. |
+| `work/attendance` | Attendance-policy versions, configured workdays, global calendar, HolidayAPI import interpretation, attendance, corrections, leave, deadline schedulers, and attendance/compliance metrics. |
+| `work/reports-ui` | Shared Thymeleaf shell/fragments, Tailwind tokens/assets, dashboards, invitation/exit-request screens, shared report datasets, Chart.js presentation, XLSX/PDF exports, and cross-product UI/accessibility consistency. |
+
+Conflict-prevention rules:
+
+- `LabtimesheetApplication` shall remain in `com.lab.labtimesheet`, shared wiring in `config`, and business code in `feature.account`, `feature.integration`, `feature.project`, `feature.task`, `feature.attendance`, `feature.notification`, or `feature.reporting`. Each feature repeats only the controller/model/model.dto/model.entity/repository/service/exception layers it needs, and tests mirror that feature/layer shape.
+- Cross-feature code may call another feature's service contract and DTOs but shall not import that feature's repository or JPA entity. Do not create empty `utils`, `common`, or `core` packages.
+- Business persistence shall use Spring Data JPA repositories. Direct SQL is limited to Flyway migrations and schema/catalog verification; services shall not use `JdbcTemplate` or embed SQL.
+
+- `work/platform` owns `src/main/resources/db/migration/**`, Maven/dependency configuration, Compose, container build files, and CI workflow files. Other branches request schema changes instead of independently allocating migration versions.
+- `work/reports-ui` owns shared templates/fragments, shared design tokens, and general UI assets. Each domain branch owns its module-specific controllers and pages while consuming those shared fragments.
+- A targeted repair shall use a clean, isolated `work/fix/<feature>/<what-fix>` branch and worktree from the taskmaster-verified current `main`. Do not use `work/<feature>/fix/<what-fix>`: the persistent `work/<feature>` ref already occupies that Git ref prefix.
+- `work/tasks` exposes focused Task query/transfer operations required by Project workflows. `work/projects` owns the transaction that removes a member or completes a Project.
+- `work/platform` owns HolidayAPI credential storage and the tested HTTP client. `work/attendance` owns preview interpretation, selection, deduplication, import, and day-off effects.
+- Attendance time and Task work time remain separate. No branch may make one mutate or prove the other.
+- Do not introduce a generic workflow engine, generic event-sourcing layer, multi-assignee Task model, Project-level day-off model, or speculative cross-module abstraction.

+
+### 4.6 Iteration 1 integration gate
+
+Integration order:
+
+1. `work/platform`
+2. `work/projects`
+3. `work/attendance`
+4. `work/tasks`
+5. `work/reports-ui`
+
+Exit demonstration:
+
+- First Admin bootstraps the installation.
+- SMTP is tested through Mailpit.
+- Admin creates and activates Mentor and Intern accounts.
+- Mentor atomically creates a Project with its first Leader, directly adds another member, and activates it.
+- Ordinary member creates a self-assigned Task; Leader creates and assigns another Task.
+- Assignee changes Task status and comments.
+- Intern checks in and checks out.
+- Every role sees only authorized navigation, actions, and records.
+- Full integrated tests pass at the iteration integration commit.
+
+Taskmaster exit result (2026-08-15): `DONE` at main integration commit `b9b150ff8ca9333e3b46d77537ec91875a970d57`, incorporating reviewed candidate `039fe25c7c2622a015c8962892dd99ff58be321d` and the verified development configuration/documentation follow-up. The final merged-main PostgreSQL 18.4 suite passed 197/197; Flyway produced 23 application tables and 56 foreign keys; Node 24/Tailwind assets built successfully; compile and full Javadoc/doclint passed on the reviewed candidate. A real local Java 25 process completed fresh bootstrap, login, five-step SMTP deferral, persistent restriction recovery, and a separate real Mailpit draft/test/activate flow with aggregate health `UP`. Temporary exit databases and Mailpit were removed; the existing development PostgreSQL service remained intact. Project/Task/Attendance role flows are protected by the approved branch suites and real desktop E2E evidence. Application containerization, Compose, CI, and production liveness/readiness hardening remain deferred as recorded above.

+Integration order:
+
+1. `work/platform`
+2. `work/tasks`
+3. `work/projects`
+4. `work/attendance`
+5. `work/reports-ui`
+
+Exit demonstration:
+
+- Admin schedules a future policy without changing historical output.
+- Admin previews/imports holidays and overrides a suggested day-off decision.
+- Intern submits cross-month leave and Mentor decides it.
+- Intern submits a missed-checkout correction; Mentor decides and may revert it inside the window.
+- Leader reassigns an unfinished Task while preserving work history.
+- Leader invites an eligible Intern; the signed-in Intern accepts or declines; Mentor direct-add safely supersedes a pending invite.

+### 6.6 Iteration 3 integration gate
+
+Integration order:
+
+1. `work/platform`
+2. `work/projects`, `work/tasks`, and `work/attendance` after their platform dependencies are available
+3. `work/reports-ui`
+
+Exit demonstration:
+
+- Historical results and checkout cutoffs remain stable after later policy/calendar changes.
+- Concurrent bootstrap, invitation/direct-add, membership exit/transfer, leadership, Task, leave, and correction operations fail safely.
+- HTML, XLSX, and PDF expose identical authorized totals.
+- Production refuses unsafe origin, proxy, datasource, or master-key configuration.
+- The same non-root image works with bundled and external PostgreSQL.
+- Work branches verify without publishing; only `main` publishes immutable SHA and convenience tags.
+- SSH deployment remains dormant without secrets or an explicit enable variable.
+- Desktop light/dark and accessibility acceptance passes; mobile/tablet remains best-effort only.
+- Full integrated tests pass at the final integration commit.
+
+## 7. Mandatory TDD workflow
+
+Every feature follows this sequence:
+
+1. Select a requirement and acceptance scenario.
+2. Write the smallest behavioral test.
+3. Run it and confirm the intended RED failure.
+4. Record the RED command/result in the appropriate evidence file.
+5. Write the minimum production code required for GREEN and add its meaningful Javadoc in the same implementation milestone.
+6. Run the focused test.
+7. Run the affected module/integration/web suite.
+8. Refactor without weakening assertions.
+9. Run the affected suite again.
+10. Record final commands/results and commit SHA.
+
+Recommended history:
+
+```text
+test(attendance): prove 09:00 check-in grace boundary [RED]
+feat(attendance): enforce inclusive check-in grace boundary [GREEN]
+```
+
+The RED and GREEN commits may be pushed together after the branch head is green. The failing historical commit proves test-first order without leaving the remote branch intentionally broken.
+
+Required evidence locations:
+
+| Test level | Evidence directory |
+|---|---|
+| Unit/state/calculation | `docs/tests/unit/` |
+| PostgreSQL/module integration | `docs/tests/integration/` |
+| MockMvc/Thymeleaf/security web behavior | `docs/tests/web/` |
+| Cross-module/browser journey | `docs/tests/e2e/` |
+
+Every evidence Markdown record must include:
+
+- requirement and scenario IDs;
+- protected behavior and why it matters;
+- test method and hand-derived expected result;
+- exact RED command and relevant failure;
+- exact GREEN and affected-suite commands/results;
+- external dependency or environment boundaries;
+- final commit SHA when available.
+
+Javadoc is part of production implementation, not a later documentation phase. Every new or materially changed production type and every declared public/protected method shall document its business contract, including non-obvious authorization, transaction/locking, lifecycle/history, unit, timezone, or deadline semantics. Do not add prose that merely repeats names. Iteration 1 alone may retrofit Javadocs after feature implementation is complete; those branch-owned retrofit commits still require affected verification and independent scoped re-review. Every later iteration and turn shall add/update Javadocs during the implementation milestone.
+
+## 8. Branch-level test emphasis
+
+| Branch | Non-negotiable evidence |
+|---|---|
+| `work/platform` | Bootstrap concurrency, token lifecycle, account/security authorization, encryption, SMTP failure, session invalidation, production-profile failure. |
+| `work/projects` | Lifecycle graphs, ownership, membership/invitation/exit/leadership intervals, transfer transactions, optimistic locking, guessed-ID denial. |
+| `work/tasks` | Parameterized status graph, Leader/member creator/assignee distinction, self-Task and same-Project generic actors, daily-minute concurrency, progress totals. |
+| `work/attendance` | Injected-Clock boundaries, PostgreSQL overlap/uniqueness, policy history, quota concurrency, schedulers and request-time guards. |
+| `work/reports-ui` | MockMvc forms/authorization, accessible rendering, report query totals, XLSX/PDF parsing/parity, critical browser journeys. |
+
+## 9. Iteration handoff protocol
+
+At each iteration boundary:
+
+1. Each branch owner updates every claimed item to `DONE`, `BLOCKED`, or returns it to `TODO`.
+2. The owner provides commit SHA, evidence paths, exact verification commands, and remaining risk.
+3. Integrate branches in the iteration's declared order.
+4. Resolve cross-module conflicts through the owning branch rather than duplicating code in the integrator.
+5. Run the full affected integrated suite.
+6. Record the integration commit in Section 3.
+7. Bring the integrated `main` into all five persistent work branches before the next iteration begins.
+
+Handoff template:
+
+```markdown
+### <tracker ID> — <short title>
+
+- Status: DONE | BLOCKED | TODO
+- Owner:
+- Requirements/scenarios:
+- RED evidence:
+- GREEN evidence:
+- Focused verification:
+- Affected-suite verification:
+- Commit SHA:
+- Remaining risk/blocker:
+- Required next owner/action:
+```
+
+## 10. Global definition of done
+
+A tracker item is complete only when:
+
+- the numbered requirement and acceptance behavior are satisfied;
+- the test existed and failed for the intended reason before production code;
+- focused and affected suites pass;
+- authorization and negative cases are covered where applicable;
+- PostgreSQL-specific rules are tested against PostgreSQL, not H2;
+- concurrency/deadline/history behavior has proportionate evidence;
+- UI behavior uses server-side authorization and shared fragments;
+- documentation/evidence paths are recorded in this tracker;
+- new or changed production types and public/protected methods have accurate Javadoc created during implementation (Iteration 1 retrofit exception only);
+- no unrelated files or another branch's ownership area were changed without coordination;
+- the final branch head is green;
+- integration does not alter totals, state graphs, or historical meaning.
+
+## 11. Progress log
+
+Append material coordination events only. Do not duplicate every commit.
+
+| Date/time | Agent/person | Event | Tracker IDs | Evidence/commit | Next action |
+|---|---|---|---|---|---|
+| — | — | Plan initialized; no implementation item claimed. | — | — | Obtain requirements approval and begin Iteration 1. |
+| 2026-08-15 | Taskmaster + five feature owners | Retrofitted targeted Lombok boilerplate after every owner fast-forwarded to the latest `main`; all five exact heads passed independent review and the combined merge passed 201 PostgreSQL 18.4 tests, compile, Javadoc/doclint, deterministic assets, and final integration review. | Iteration 1 maintenance | Platform `c9499732`; Project `58712710`; Task `469d7e27`; Attendance `5ddbd75f`; Reporting `8500cb6e`; integrated `b764707716f54ad164547b087f658c277cf46e0f`; `docs/tests/unit/lombok-*-boilerplate.md` | Push reviewed `main`, then fast-forward all five persistent work branches before Iteration 2 work. |

+description: Use when initiating, resuming, integrating, or completing a multi-branch Lab Timesheet iteration defined by .agents/PROJECT_PLAN.md.
+---
+
+# Orchestrate a Lab Timesheet Iteration
+
+Run the iteration continuously from repository audit through an evidence-backed local exit demonstration. Preserve the five long-lived work branches and keep business features isolated behind public services and DTOs.
+
+## Load authority and preserve state
+
+1. Read the repository `AGENTS.md`, `.agents/PROJECT_PLAN.md`, `PRODUCT.md`, `DEVELOPMENT.md`, `TESTING.md`, and the applicable numbered requirements in `labtimesheet-docs-hub/requirements-specification.md`.
+2. Apply authority in this order: current user decisions, numbered requirements, approved plan, tests/code, then inference.
+3. Inspect every worktree and the root `git status` before mutation. Record and preserve unrelated dirty or untracked files.
+4. Confirm the actual Maven, Spring Boot, Java, Node, PostgreSQL, Flyway, and Testcontainers versions. Use the documented project baseline even if a newer JDK is installed.
+5. Create or update the active goal and plan only when the user requests goal-mode execution.
+
+## Enforce the project structure
+
+Keep `LabtimesheetApplication` in `com.lab.labtimesheet`, shared wiring in `config`, and business code under:
+
+```text
+feature.account
+feature.integration
+feature.project
+feature.task
+feature.attendance
+feature.notification
+feature.reporting
+```
+
+Repeat only the layers a feature needs: `controller`, `model`, `model.dto`, `model.entity`, `repository`, `service`, and `exception`. Mirror these packages in tests.
+
+- Call another feature only through its concrete public service methods and DTOs.
+- Never import another feature's repository or JPA entity.
+- Use Spring Data JPA for business persistence.
+- Limit direct SQL to Flyway and schema/catalog verification.
+- Do not add empty `common`, `core`, `utils`, or boundary-placeholder packages.
+- Do not add one-implementation interfaces, shadow mappings of foreign tables, or speculative abstractions.
+
+Use the installed Lombok processor as the default for safe Java boilerplate:
+
+- `@RequiredArgsConstructor` for injection-only constructors with required final dependencies;
+- targeted `@Getter`, `@Setter`, and protected `@NoArgsConstructor` instead of blanket `@Data`;
+- no generated JPA entity `equals`, `hashCode`, or `toString` over mutable state, associations, or secrets;
+- records remain records for immutable DTOs and commands;
+- explicit constructors and methods remain when they validate, normalize, enforce invariants, preserve history, define identity, or select qualified dependencies.
+
+Require each owner to audit its production package, record a source-contract RED for eligible handwritten boilerplate, make the smallest behavior-preserving Lombok conversion, and prove compile/Javadoc, Spring injection, JPA mapping, template property access, and affected behavior remain green. Do not add annotations that generate unused API.
+
+## Establish the shared baseline first
+
+Before dispatching feature work:
+
+1. Verify the Maven wrapper, application profile, Flyway baseline, PostgreSQL connectivity, test-only clock/encryption, and frontend asset toolchain.
+2. Run a clean baseline test and capture any pre-existing failure separately.
+3. Run the application locally against a disposable or dedicated PostgreSQL service. A PostgreSQL or Mailpit test container is acceptable; do not containerize the application when the exit gate says local process.
+4. Commit the shared platform foundation before dependent branches use it.
+5. Hand off only full immutable commit SHAs from clean worktrees.
+
+## Own five branches and worktrees
+
+Use exactly these persistent branches unless the user changes the plan:
+
+| Branch | Ownership |
+|---|---|
+| `work/platform` | Baseline, migration, accounts, security, bootstrap, integrations, notification plumbing |
+| `work/projects` | Projects, membership, leadership, lifecycle, project authorization |
+| `work/tasks` | Tasks, comments, work logs, status, task progress |
+| `work/attendance` | Policy, calendar, attendance, corrections, leave, metrics |
+| `work/reports-ui` | Shared Thymeleaf UI, dashboards, reports, exports |
+
+For a targeted repair outside the next iteration, create a clean isolated
+`work/fix/<feature>/<what-fix>` worktree from the taskmaster-verified current
+`main`. Do not use `work/<feature>/fix/<what-fix>`: the persistent
+`work/<feature>` ref already occupies that Git ref prefix.
+
+Create one isolated worktree per branch. Give each implementation agent explicit ownership, tell it other agents share the repository, forbid reverting others' work, require medium-milestone local commits, and forbid push unless separately authorized.
+
+Before any owner edits its module, require it to:
+
+1. verify its worktree has no uncommitted changes;
+2. confirm the taskmaster's exact latest `main` SHA;
+3. fast-forward its persistent work branch to that SHA with `git merge --ff-only main`;
+4. prove `git rev-parse HEAD` equals the supplied main SHA;
+5. stop rather than resolving unexpected divergence or overwriting user work.
+
+Store durable coordination under `.superpowers/sdd/PROJECT_PLAN/`:
+
+- `progress.md` with exact SHAs, dependency pins, tests, blockers, and review rounds;
+- one task report per branch;
+- review packages and reviewer reports.
+
+Trust this ledger and Git history after context compaction. Never redispatch a completed milestone.
+
+## Require RED, GREEN, Javadoc, and companion evidence
+
+For every behavior:
+
+1. Read its requirement and acceptance scenario IDs.
+2. Write the narrowest production-shaped test first.
+3. Run it and record RED for the expected missing behavior, not an environment or test defect.
+4. Implement the minimum coherent change and its meaningful Javadoc in the same milestone. Document every new or materially changed production type and declared public/protected method, emphasizing business contracts, authorization, transactions/locking, state/history semantics, units, and time boundaries rather than restating names.
+5. Run focused GREEN, affected-suite verification, then the branch-wide suite.
+6. Refactor only while tests remain green.
+7. Commit when a medium milestone is complete.
+
+Use PostgreSQL 18.4 Testcontainers for persistence semantics; do not substitute H2. Keep time and randomness controllable. Test public outcomes, persisted state, authorization denial, and boundary cases.
+
+Create a Markdown evidence record under the matching directory:
+
+```text
+docs/tests/unit/
+docs/tests/integration/
+docs/tests/web/
+docs/tests/e2e/
+```
+
+Start from that directory's `_TEMPLATE.md`. Every record must include requirement/scenario IDs, protected behavior, test method, hand-derived expected result, exact RED command/result, exact GREEN and affected-suite commands/results, implementation milestone, and external-test boundaries. Never replace executable evidence with a verbal claim.
+
+Iteration 1 is the only retrofit exception: after all feature tasks finish, return each branch to its original owner to add missing Javadocs before integration, rerun affected verification, commit, and undergo scoped re-review. In every later iteration or turn, reject delayed Javadoc cleanup; it belongs in the implementation milestone.
+
+## Merge dependencies by immutable pin
+
+Derive the dependency graph from the current iteration plan. For Iteration 1, use:
+
+```text
+platform foundation
+  -> projects base
+  -> attendance
+  -> tasks (projects + attendance public APIs)
+  -> projects activation guard (final Task query API)
+  -> reports-ui (final public dashboard APIs)
+```
+
+- A producer reports a clean full SHA and public API before a consumer merges it.
+- Never merge a moving branch or a short ambiguous SHA.
+- Preserve dirty consumer work during the merge and immediately rerun its structure test.
+- If a consumer needs data, add the smallest producer-owned public query DTO/service method; never map or query the producer's tables locally.
+- Keep final integration order from `.agents/PROJECT_PLAN.md` even when development dependencies require a temporary producer/base round trip.
+- Reuse the last reviewed consumer branch as the integrated candidate when it already contains every approved producer pin in order. An extra integration branch adds no safety by itself.
+- After a Platform merge, run the architecture test and every `@WebMvcTest` controller slice. Global advice and shared beans can invalidate otherwise unrelated slice fixtures; fix only the test fixture, never production security to accommodate a slice.
+
+## Coordinate agents without losing control
+
+Let the five owners work in parallel where dependencies permit. Resolve normal in-scope questions without pausing the run. Stop only for a genuine blocker, consequential ambiguity, destructive action, or sensitive external effect requiring user approval.
+
+For a sensitive action, state the exact effect and obtain approval in the root task. If a child cannot inherit that approval, the root may apply only the isolated approved patch; return the worktree to its owner for tests, evidence, self-review, and commit.
+
+Do not accept an agent's completion claim alone. Require:
+
+- exact branch and full SHA;
+- clean worktree;
+- focused, affected, and full test counts;
+- confirmation that new/changed production APIs carry accurate Javadoc;
+- a list of Lombok conversions and explicit boilerplate deliberately retained with its business reason;
+- evidence/report path;
+- public API handoff;
+- blockers and unverified boundaries;
+- confirmation of no push.
+
+## Review only after all five owners finish
+
+After every implementation owner reports `DONE`, dispatch independent code-review assignments, one branch per assignment. Give each reviewer the plan/requirements paths, branch report, ledger, merge base, full diff package, and exact structure/TDD constraints.
+
+Each review must return both spec-compliance and code-quality verdicts with file/line evidence. For Critical or Important findings:
+
+1. Send the complete finding list back to that branch's original owner.
+2. Require a focused regression test, RED when applicable, GREEN, affected suite, evidence update, and a fix commit.
+3. Dispatch an independent scoped re-review of only the fix range.
+4. Repeat up to five rounds; use a fresh stronger fixer for rounds four and five.
+5. At the cap, record a reasoned ruling for non-load-bearing findings or stop on a load-bearing blocker.
+
+Do not merge a branch with unresolved load-bearing findings.
+
+## Prove the iteration exit gate
+
+Integrate only reviewed immutable branch SHAs in the plan's order. Then verify from the integrated tree:
+
+1. `git diff --check` and package/JPA architecture tests.
+2. Flyway replay against fresh PostgreSQL and the required table/foreign-key catalogue checks.
+3. Full Maven tests on the documented Java version and PostgreSQL engine.
+4. Frontend asset build on the pinned Node version.
+5. A local application process connected to the configured PostgreSQL service.
+6. Health/readiness and the iteration's real role-correct web workflow.
+7. No application containerization when explicitly deferred.
+8. Root dirty-state preservation, clean reviewed worktrees, and no unauthorized push.
+
+Keep environment authority explicit:
+
+- real `.env` files are local and ignored;
+- `.env.example` contains placeholders only;
+- the development Spring profile maps every required runtime value from the environment;
+- Admin-console SMTP and HolidayAPI secrets never move into `.env`;
+- configuration-only work uses a shell/configuration RED and real application smoke test instead of an artificial Java unit test.
+
+If SMTP participates in health, exercise both states deliberately: application startup with SMTP deferred, and aggregate health with a real temporary Mailpit connection. Report the distinction instead of calling one state universally healthy.
+
+Store cross-module browser journeys in `docs/tests/e2e/`. Before completion, update every Iteration row and the durable progress ledger; stale `IN_PROGRESS` rows are an incomplete gate even when tests pass.
+
+Review source Javadocs against behavior as part of the branch and integration diff; stale or content-free Javadoc does not satisfy the gate.
+
+## Merge reviewed Iteration work to main
+
+Only enter this phase with explicit user authority.
+
+1. Add any final environment example, profile configuration, implementation-status README, development guide, and testing/TDD guide to the integrated candidate under RED/GREEN evidence.
+2. Run the complete PostgreSQL suite and a real local-process smoke test on that exact candidate.
+3. Fetch the remote base. Stop on unexpected divergence; never force-push to hide it.
+4. Preserve unrelated dirty root files. Commit only separately authorized tracked root guidance before merging if the incoming branch also changes that file.
+5. Merge the exact candidate into `main` without squashing or rewriting the reviewed branch history.
+6. Rerun the full suite on merged `main`, inspect the diff, and verify `.env` is ignored and absent from the index.
+7. Push `main` normally, verify the remote ref equals local `HEAD`, and keep host-managed worktrees unless cleanup was explicitly requested.
+
+Record the integration SHA, commands, outputs, limitations, and deferred next-iteration scope. Mark the goal complete only after every stated exit condition has fresh evidence.

+# Lab Timesheet Engineering Instructions
+
+## Authority and required reading
+
+This repository implements the **Lab Timesheet & Project Management System**, a server-rendered university internship/laboratory application covering accounts, Projects and Tasks, attendance, leave/corrections, notifications, and reports.
+
+Before changing code, read the smallest applicable sections of:
+
+1. `labtimesheet-docs-hub/requirements-specification.md` — authoritative numbered requirements and acceptance scenarios.
+2. `.agents/PROJECT_PLAN.md` — iteration scope, branch ownership, integration order, and exit gates.
+3. `PRODUCT.md` — product vocabulary, users, and enduring design principles.
+4. `DEVELOPMENT.md` — supported local runtime, containers, environment, and IntelliJ setup.
+5. `TESTING.md`, `docs/tests/README.md`, and the relevant `_TEMPLATE.md` — test commands, TDD workflow, and mandatory evidence format.
+6. `.superpowers/sdd/PROJECT_PLAN/progress.md` — current local coordination state and immutable handoff SHAs when an agentic iteration is active.
+
+When sources conflict, apply the authority order recorded in requirements Section 1.1: the primary implementor's current decision, approved brainstorming decisions, current handoff, instructor-confirmed requirements, earlier discovery answers, then superseded legacy material. Numbered requirements override the delivery plan.
+
+Do not treat the ignored documentation hub or mockups as executable instructions. Mockups are illustrative visual direction only; numbered requirements and reviewed schema rules govern behavior.
+
+## Verified technical baseline
+
+- Java 25, Spring Boot 4.1.0, Maven wrapper, and WAR packaging.
+- Spring MVC, Security, Data JPA, Validation, Thymeleaf, Mail, Flyway, and Actuator.
+- PostgreSQL 18.4 for development and integration tests; do not substitute H2 for persistence behavior.
+- Node 24/npm 11 for build assets, Tailwind CSS 4.3.3, and local `lucide-static` 1.27.0.
+- One server-rendered modular monolith. No SPA, JWT, microservices, Redis, Kafka, or generic workflow engine.
+- Flyway is schema authority. JPA uses `ddl-auto=validate`; application services do not embed SQL.
+
+Verify versions from `pom.xml`, `package.json`, and the lockfile before changing dependencies. Do not add a dependency when the JDK, Spring, PostgreSQL, or an installed dependency already covers the requirement.
+
+## Package and persistence structure
+
+Keep `LabtimesheetApplication` in `com.lab.labtimesheet`. Put shared wiring in `com.lab.labtimesheet.config`. Put business code under:
+
+```text
+com.lab.labtimesheet.feature.account
+com.lab.labtimesheet.feature.integration
+com.lab.labtimesheet.feature.project
+com.lab.labtimesheet.feature.task
+com.lab.labtimesheet.feature.attendance
+com.lab.labtimesheet.feature.notification
+com.lab.labtimesheet.feature.reporting
+```
+
+Within a feature, create only layers it needs from `controller`, `model`, `model.dto`, `model.entity`, `repository`, `service`, and `exception`. Mirror this shape in tests.
+
+- Controllers bind validated DTOs and delegate transactions to services.
+- Services use their feature's Spring Data JPA repositories and models.
+- Cross-feature calls use concrete public services and DTOs only.
+- Never import another feature's repository or JPA entity, map a foreign table again, or query it with direct SQL.
+- Direct SQL is limited to Flyway and schema/catalog verification.
+- Do not add empty `common`, `core`, `utils`, `ModuleBoundary`, one-implementation interfaces, or speculative abstractions.
+- Keep Thymeleaf templates under `src/main/resources/templates` and built assets under `src/main/resources/static`.
+
+Preserve the domain boundaries: attendance time never derives Task work time; historical policies, memberships, leadership, creator/assignee attribution, and decisions do not silently move when current configuration changes.
+
+## Lombok is the default for Java boilerplate
+
+Lombok is already installed and configured as an annotation processor. Use it by default when it removes mechanical Java without hiding a business rule.
+
+- Use `@RequiredArgsConstructor` for Spring controllers, services, configuration classes, and other components whose constructor only assigns required `final` dependencies. Keep an explicit constructor when it validates input, transforms data, selects among same-typed beans, or documents a non-trivial public contract.
+- Use targeted annotations such as `@Getter`, `@Setter`, `@NoArgsConstructor`, and `@AllArgsConstructor`; use the smallest set that matches the actual API. Do not use `@Data` as a blanket shortcut.
+- For JPA entities, never let Lombok generate `equals`, `hashCode`, or `toString` across entities, lazy associations, mutable fields, or encrypted secrets. Prefer `@Getter` and `@NoArgsConstructor(access = AccessLevel.PROTECTED)`, keep domain constructors and mutation methods explicit, and add individual setters only when a framework genuinely needs them.
+- Keep Java records for immutable DTOs and commands. Replacing a record with a Lombok class creates more code and is not an improvement.
+- Use `@Slf4j` only when the class actually logs. Do not add builders, withers, or generated setters speculatively.
+- Do not retain handwritten constructors, getters, setters, `equals`, `hashCode`, or `toString` that are purely mechanical and safely covered by the targeted Lombok annotation. Preserve explicit methods that enforce invariants, normalize values, maintain history, or define identity semantics.
+- After a Lombok refactor, inspect the generated API contract, run compile/Javadoc plus the affected tests, and confirm JPA mappings, Spring injection, Thymeleaf property access, serialization, and security-sensitive redaction remain unchanged.
+
+This rule applies during implementation, not as deferred cleanup. A source-audit RED may prove existing eligible boilerplate before a behavior-preserving Lombok refactor; the GREEN gate is the same public behavior with less handwritten code.
+
+## Javadoc is part of implementation
+
+Add meaningful Javadoc while implementing production Java code, in the same milestone and before its final GREEN/commit.
+
+- Document every new or materially changed production type and every public or protected method declared in source.
+- Explain business purpose and non-obvious contracts: authorization/context requirements, transaction or locking behavior, state transitions, history retention, side effects, units, timezone/deadline boundaries, and null/empty semantics.
+- Keep inherited Javadoc for a true override when it fully describes the contract. Generated Lombok methods, trivial accessors, and tests do not need duplicate prose.
+- Do not write comments that merely restate names or implementation steps. If a contract cannot be explained clearly, simplify the code or clarify the requirement.
+- Update Javadoc whenever behavior changes; stale Javadoc is a defect.
+
+Iteration 1 is the one approved retrofit exception: feature owners add missing Javadocs after their implementation tasks finish, then rerun affected verification and undergo scoped re-review. Every later iteration and turn must add Javadocs during implementation, not as cleanup.
+
+## Mandatory TDD and evidence
+
+Use strict RED → GREEN → affected-suite verification → refactor:
+
+1. Select requirement and acceptance-scenario IDs.
+2. Write the smallest production-shaped failing test.
+3. Run it and prove the RED is the missing behavior, not a broken fixture or environment.
+4. Record the exact RED command/result in the matching evidence file.
+5. Implement the minimum behavior and its Javadoc.
+6. Run focused GREEN, then the affected suite; refactor only while green.
+7. Update evidence with exact commands/results and external boundaries.
+8. Commit a medium-sized green milestone locally.
+
+Evidence belongs under:
+
+```text
+docs/tests/unit/
+docs/tests/integration/
+docs/tests/web/
+docs/tests/e2e/
+```
+
+Copy the directory's `_TEMPLATE.md`; do not invent a second format. PostgreSQL-specific behavior uses PostgreSQL 18.4 Testcontainers. Security, ownership, concurrency, deadlines, and history require negative and boundary tests proportionate to risk.
+
+## Five-branch ownership and subagent workflow
+
+The persistent implementation branches are:
+
+| Branch | Primary ownership |
+|---|---|
+| `work/platform` | Maven/app baseline, Flyway, accounts/security/bootstrap, integrations/notifications, container and CI assets |
+| `work/projects` | Projects, membership/leadership intervals, invitations/exits, lifecycle, Project authorization |
+| `work/tasks` | Tasks, actor/assignee rules, comments, work logs, status, progress |
+| `work/attendance` | Policy/calendar, attendance, corrections, leave, schedulers, metrics |
+| `work/reports-ui` | Shared Thymeleaf UI, dashboards, reports/exports, UI/accessibility consistency |
+
+For a multi-branch iteration:
+
+- Use one worktree and one named owner/subagent per branch. Tell every owner that other agents share the repository and it must not revert others' work.
+- Before starting assigned module work, every owner verifies its worktree is clean, fetches or uses the taskmaster-verified latest `main`, and fast-forwards its persistent branch to that exact main SHA. Do not build new work on a stale pre-integration branch, and do not use a merge that would rewrite or discard branch history.
+- A targeted repair uses a clean, isolated `work/fix/<feature>/<what-fix>` branch and worktree from the taskmaster-verified current `main`. Do not use `work/<feature>/fix/<what-fix>`: the persistent `work/<feature>` ref already occupies that Git ref prefix.
+- Every targeted repair starts from the taskmaster-verified latest `main`, uses TDD RED → GREEN, adds Javadoc during implementation, records companion evidence, undergoes independent review, and uses a normal, non-force merge only when separately authorized.
+- Establish and commit the platform foundation before dependent persistence work.
+- Exchange only full immutable SHAs from clean worktrees; never merge a moving branch or ambiguous short SHA.
+- Preserve branch ownership. Request a producer-owned service/DTO boundary instead of reading its tables from a consumer.
+- Commit each medium green milestone locally. Do not push, publish, deploy, force, rewrite history, or merge to `main` without explicit authority.
+- After all five owners report DONE, run independent read-only reviews of every branch. Return Critical/Important findings to the original owner with a regression test where applicable, GREEN evidence, a fix commit, and scoped re-review. Do not integrate unresolved load-bearing findings.
+- Integrate reviewed exact heads only in the current iteration's order from `.agents/PROJECT_PLAN.md`, then run the full integrated exit gate.
+
+Keep durable coordination under `.superpowers/sdd/PROJECT_PLAN/`: progress ledger, branch reports, review findings, immutable SHAs, commands/results, blockers, and integration evidence. Do not redispatch completed milestones after context compaction.
+
+## Local commands and runtime
+
+Default development expects PostgreSQL on port `55432`; override with `LAB_DB_URL`, `LAB_DB_USERNAME`, and `LAB_DB_PASSWORD`. SMTP defaults to localhost Mailpit port `1025` and can be overridden with `LAB_SMTP_HOST`/`LAB_SMTP_PORT`. Never commit real secrets.
+
+```bash
+export JAVA_HOME=/opt/homebrew/opt/openjdk@25
+export PATH="$JAVA_HOME/bin:$PATH"
+./mvnw test
+npm ci
+npm run build
+./mvnw spring-boot:run
+```
+
+When using local OrbStack Testcontainers, set the actual Docker socket for that machine. Tests must not depend on the developer database or a real SMTP server.
+
+Before completion, run focused tests, the affected suite, the full suite appropriate to the branch, frontend build when assets changed, `git diff --check`, and an adversarial diff review. The integrated iteration additionally requires Flyway/PostgreSQL validation and a real local Java process connected to PostgreSQL. Production container checks supplement those gates; they do not substitute for them.
+
+The root `Dockerfile`, `compose.yaml`, and `.env.compose.example` are production-only. Development runs Java from the IDE or Maven as documented in `DEVELOPMENT.md`. Only `main` may publish container images. Native ARM64 publication is gated by the repository variable `ARM64_RUNNER_AVAILABLE`; leave it absent or false unless a trusted `ubuntu-latest-arm` runner is online.
+
+## Post-iteration integration and push
+
+- Use the final reviewed consumer branch as the integration candidate when it already contains every approved producer SHA in plan order; do not create an extra integration branch without a concrete need.
+- Keep real `.env` files untracked. Commit only `.env.example` placeholders and environment-backed Spring profile configuration. SMTP and HolidayAPI credentials managed by the Admin console do not belong in `.env`.
+- Keep `README.md`, `DEVELOPMENT.md`, and `TESTING.md` aligned with the merged application. Document only commands and workflows that were exercised or directly verified.
+- Configuration and README changes made after feature review still require a configuration-contract RED, focused GREEN, the complete PostgreSQL suite, `git diff --check`, and a local-process smoke test before merging.
+- A global MVC advice or shared configuration bean can affect every `@WebMvcTest` slice. After merging Platform changes, run all controller slices and add only the missing test fixture bean; do not weaken the production advice.
+- Record real cross-module browser journeys under `docs/tests/e2e/`, not `docs/tests/web/`, and update `.agents/PROJECT_PLAN.md` plus the progress ledger before declaring the iteration complete.
+- Before merging to `main`, fetch its upstream and stop if the remote moved unexpectedly. Preserve unrelated root changes, stage only authorized paths, merge without rewriting history, rerun the full suite on the exact merged tree, then push normally and verify the remote SHA.
+- Worktrees under `/private/tmp` are host-managed. Keep the five branch worktrees and branches after integration unless the user explicitly requests cleanup.
+
+## Safety and scope
+
+- Inspect `git status` before editing and preserve unrelated dirty/untracked files.
+- Use server time and an injectable `Clock` for deadline behavior; never trust browser event timestamps.
+- Keep CSRF, authorization, password hashing, validation, and ownership checks active in every environment.
+- Never print, persist, or return raw activation/reset tokens except the approved immediate delivery path; persist only their hashes.
+- Desktop is the supported UI target. Mobile responsiveness is best-effort and has no mockup/parity gate.
+- Iteration scope is exact. Leave later-iteration capabilities TODO rather than adding placeholders or partial frameworks.

+# Production Container Deployment
+
+These files deploy Lab Timesheet in production. They are not the development workflow; continue using [DEVELOPMENT.md](DEVELOPMENT.md) for IDE work.
+
+## 1. Prepare the host
+
+Install Docker Engine and Docker Compose v2.20 or newer. Put an HTTPS reverse proxy in front of the application. By default, Compose binds the application only to `127.0.0.1:8080`.
+
+Copy [`.env.compose.example`](.env.compose.example) to a protected path outside the repository:
+
+```bash
+sudo install -d -m 0700 /etc/labtimesheet
+sudo install -m 0600 .env.compose.example /etc/labtimesheet/compose.env
+sudo editor /etc/labtimesheet/compose.env
+```
+
+Generate `LAB_SECURITY_MASTER_KEY` with `openssl rand -base64 32`. Use an immutable `sha-<full-commit>` application image tag. Never place Admin-managed SMTP or HolidayAPI credentials in this file.
+
+## 2. Choose the database topology
+
+### Bundled PostgreSQL 18.4
+
+Keep the example JDBC host `postgres`, then run:
+
+```bash
+docker compose --env-file /etc/labtimesheet/compose.env --profile bundled-db up -d
+docker compose --env-file /etc/labtimesheet/compose.env ps
+```
+
+The application waits for PostgreSQL health and stores database files in the `postgres_data` named volume.
+
+### External PostgreSQL
+
+Set `LAB_DB_URL`, `LAB_DB_USERNAME`, and `LAB_DB_PASSWORD` for the external database. Do not enable the `bundled-db` profile:
+
+```bash
+docker compose --env-file /etc/labtimesheet/compose.env up -d app
+docker compose --env-file /etc/labtimesheet/compose.env ps
+```
+
+The same application image is used in both modes.
+
+## 3. Health and operation
+
+- Liveness: `GET /actuator/health/liveness`
+- Readiness: `GET /actuator/health/readiness` (includes PostgreSQL)
+- Logs: `docker compose --env-file /etc/labtimesheet/compose.env logs -f app`
+
+The container runs as UID/GID `10001`, with a read-only root filesystem, no Linux capabilities, and only `/tmp` writable. TLS termination is intentionally outside this Compose example.
+
+Back up PostgreSQL with database-aware tooling such as `pg_dump`. The named volume survives container replacement, but it is not a backup. Test restore procedures before upgrades.
+
+To update or roll back, change `LAB_IMAGE` to the required immutable SHA tag and run `docker compose ... up -d` again. Keep the previous SHA recorded until the new image is healthy.
+
+## 4. Gitea Actions setup
+
+Configure these repository settings:
+
+| Kind | Name | Value |
+|---|---|---|
+| Variable | `ARM64_RUNNER_AVAILABLE` | `true` only while a trusted `ubuntu-latest-arm` runner is registered and online; otherwise omit it or set `false` |
+| Secret | `REGISTRY_TOKEN` | Token for the triggering Gitea account with package read/write access |
+
+The workflow publishes `git.sechmachine.io.vn/sechmachine/labtimesheet` and authenticates as the triggering Gitea account. `verify.yml` runs for every pull request and push. `container.yml` runs only when manually dispatched or when `main` is pushed, and it repeats verification before either architecture build. Manual runs build without publishing. A push to `main` publishes immutable `sha-<commit>` and convenience `main` tags.
+
+When ARM64 is disabled, those canonical tags remain valid AMD64 images and the workflow succeeds. When it is enabled, the native ARM runner publishes an architecture tag and the final job replaces the canonical tags with a combined AMD64/ARM64 manifest. Gitea cannot discover an unavailable runner from inside an unscheduled job, so the repository variable is the deliberate availability gate.
+
+The workflows stop at verification and image publication. They do not contain SSH deployment or receive host deployment secrets.

+# Design System: Lab Timesheet
+
+## Overview
+
+**Creative North Star: "The Calm Operations Ledger"**
+
+Lab Timesheet is a permission-aware operations workspace. It favors legible state, compact controls, clear ownership, and reviewable records over decorative dashboard theater. The Vercel/shadcn-style reference is translated into server-rendered Thymeleaf surfaces with a stable shell and one role-correct task per page.
+
+The visual system is quiet but not empty: thin structure, disciplined spacing, tabular data, and rare semantic color make consequential actions and deadlines easy to find. Example content must always be identified as illustrative.
+
+**Key Characteristics:**
+
+- Cool near-white surfaces with charcoal text.
+- Fixed desktop sidebar and compact page header.
+- Dense tables and direct forms as the main working surfaces.
+- Black primary actions; color reserved for focus, status, warning, and error.
+- Rounded corners and restrained ambient shadow, never floating card mosaics.
+
+## Colors
+
+The light palette uses cool neutral layers; dark mode must be designed from the supplied near-black references rather than mechanically inverted from these values.
+
+### Primary
+
+- **Operational Ink** (`#15171a`): primary text, brand mark, and primary actions.
+- **Controlled Accent** (`#3157e7`): focus, selected data, and rare contextual emphasis.
+
+### Neutral
+
+- **Work Canvas** (`#f6f7f8`): page background.
+- **Navigation Shell** (`#f0f1f2`): desktop sidebar.
+- **Record Surface** (`#ffffff`): forms, tables, panels, and active navigation.
+- **Muted Surface** (`#f7f8f9`): headers, tabs, and supporting rows.
+- **Ledger Border** (`#dfe1e5`): default one-pixel structure.
+- **Control Border** (`#c9cdd3`): inputs and action outlines.
+- **Muted Text** (`#626a75`) and **Subtle Text** (`#818894`): secondary and tertiary copy.
+
+### Semantic
+
+- **Success** (`#087a48`), **Warning** (`#996000`), and **Danger** (`#b42318`) communicate state with text and shape, never color alone.
+
+**The Rare Color Rule.** Neutral structure carries the interface. Semantic and accent colors appear only when they clarify state, focus, validation, or a consequential decision.
+
+## Typography
+
+**Display and Body Font:** the local system sans stack (`ui-sans-serif`, platform UI fonts, `Segoe UI`, sans-serif). No remote font is required.
+
+**Character:** compact, familiar, and operational. Weight and spacing establish hierarchy without oversized marketing display type.
+
+### Hierarchy
+
+- **Page headline** (700, `25px`, 1.2): one per screen.
+- **Panel title** (600–700, `14px`): names the current dataset or decision surface.
+- **Body** (400, `14px`, 1.45): instructions and explanatory copy, normally no wider than 72ch.
+- **Data** (500–650, `12px`): dense tables and facts; numeric summaries use tabular numerals.
+- **Label** (650, `11px`): fields and supporting metadata.
+- **Navigation group label** (750, `10px`, uppercase, `0.08em`): rare structural labels only.
+
+**The One Headline Rule.** Each screen gets one page headline; hierarchy below it is compact and task-oriented.
+
+## Layout
+
+Desktop is the supported product target. The shell uses a 236px sidebar and a minimum-width content column, with a 60px header and 24–26px content inset. The implementation target may round the sidebar to approximately 16rem and its collapsed rail to approximately 4rem.
+
+Content uses a four-cell metric strip, full-width table/form panels, and an occasional two-column decision or form/detail layout. The primary record or decision remains in the first viewport at 1365×900. Tables may scroll horizontally inside their own region but must not create page-level overflow.
+
+Mobile and tablet responsiveness is best-effort only. It may reflow or scroll to avoid preventable breakage, but it is not required to provide complete workflow parity and has no dedicated mockup set.
+
+## Elevation & Depth
+
+Structure comes primarily from surface contrast and one-pixel borders. The only recurring ambient shadow is a soft panel lift (`0 10px 28px rgba(20,25,35,.06)`); active navigation and tabs use a smaller `0 1px 2px` shadow. Deep stacks and card-within-card effects are not part of this world.
+
+**The Flat-First Rule.** Use border and tone before shadow. Shadow confirms grouping; it does not turn every region into a floating card.
+
+## Shapes
+
+Controls use an 8px radius, segmented containers 9px, primary panels 12px, and centered dialogs 14px. Status badges may be fully rounded because their small silhouette communicates state. Larger containers are not pill-shaped. Borders are neutral and one pixel.
+
+## Components
+
+### Buttons
+
+- **Primary:** Operational Ink background, white text, 8px radius, 37px minimum height.
+- **Secondary:** white background, stronger neutral border, same geometry.
+- **Danger:** pale danger surface with explicit consequence copy; destructive actions require confirmation.
+- **Focus:** visible high-contrast focus treatment is mandatory in implementation.
+
+### Tables and panels
+
+- Panels use white surface, one-pixel border, 12px radius, and optional ambient shadow.
+- Table headers use muted surface, compact uppercase labels, and stable desktop columns.
+- Status is shown with a text badge plus a non-color cue.
+- Empty, unavailable, stale, and access-denied states replace the table body with direct operational copy.
+
+### Inputs and forms
+
+- Fields use white surface, stronger neutral border, 8px radius, and 39px minimum height.
+- Labels stay visible; placeholder text never replaces a label.
+- Validation preserves safe input, associates field errors, and adds a form-level error summary.
+- Form actions appear once, at the end of the form; list/detail actions live in the page header.
+
+### Navigation
+
+- The desktop sidebar shows only authorized destinations.
+- Active navigation uses a white surface and ink text without a colored stripe.
+- The lower account area exposes profile, theme, and logout.
+- Icon-only collapsed navigation requires accessible names and tooltips.
+
+### Metric strips and tabs
+
+- Metric strips are one bounded row divided by one-pixel rules, not separate floating cards.
+- Tabs are compact segmented controls; a tab labels a true view switch, not a decorative category badge.
+
+## Do's and Don'ts
+
+### Do:
+
+- **Do** put the user’s current task, deadline, record state, and authorized action in the first viewport.
+- **Do** use server-authoritative dates/times and honest illustrative-data labels.
+- **Do** keep role, ownership, membership, leadership, and assignee distinctions visible in copy and action placement.
+- **Do** supply accessible labels, keyboard focus, error summaries, and chart text/table alternatives.
+
+### Don't:
+
+- **Don't** use gradients, glass effects, remote fonts, decorative charts, or oversized marketing headings.
+- **Don't** use cards as the default container for every piece of content.
+- **Don't** expose an action merely because the current global role sounds powerful enough; contextual authorization wins.
+- **Don't** treat the desktop mockups as mobile requirements or imply mobile workflow parity.
+- **Don't** invent production endorsements, adoption metrics, or unlabeled example records.

+
+## Platform
+
+web
+
+## Stack
+
+- Java 25 and Spring Boot 4.1.0.
+- Maven-built, server-rendered Spring MVC modular monolith organized by business feature.
+- Spring Security, Spring Data JPA, Bean Validation, Thymeleaf, Spring Mail, and Flyway.
+- Tailwind CSS 4 with Node 24 LTS used only for frontend build assets.
+- PostgreSQL 18.4 across development, integration testing, and production.
+- No SPA framework, JWT authentication, microservices, Redis, Kafka, or generic workflow engine in v1.
+
+## Users
+
+- **Admins** operate accounts, internship lifecycles, attendance policy, the global calendar, SMTP, HolidayAPI, and system configuration. They inspect Project and attendance progress but do not perform Mentor or Project Leader work.
+- **Mentors** own Projects, directly manage membership and leadership, decide membership exits, monitor Project and Intern progress, comment on Tasks, inspect attendance, and decide leave and missed-checkout corrections.
+- **Interns** check in and out, request leave and missed-checkout corrections, respond to their own Project invitations, request/cancel their own Project exit, participate in multiple Projects, create self-assigned Tasks, perform assigned Tasks, comment, update their own assigned Task status, and record Task work.
+- A **Project Leader** is an Intern with a current leadership term for one Project. It is contextual authority, never a global account role. The Leader may invite eligible Interns, request a member's removal, and manage Task definitions/assignment inside that Project.
+- The product is reviewed and maintained by a university project team and its instructor or appointed maintainer.
+
+## Product Purpose
+
+Lab Timesheet supports a university laboratory or internship program by bringing account administration, attendance, leave, missed-checkout correction, Project work, Task progress, notifications, and authorized reporting into one working system.
+
+Success means each role can complete its permitted work without spreadsheets or informal message trails, while deadlines, decisions, historical attribution, and report totals remain explainable and auditable.
+
+## Positioning
+
+The product joins attendance oversight and Project delivery without pretending they are the same measurement. Check-in and checkout establish attendance; dated Task work logs establish Project effort. Effective-dated policy and frozen historical allocations prevent later configuration changes from rewriting past results.
+
+## Operating Context
+
+- The business timezone is `Asia/Ho_Chi_Minh`; business dates use the applicable attendance-policy timezone and persisted event instants are treated as UTC.
+- The system is operated as one server-rendered web application with PostgreSQL. Desktop browsers are the supported interface target; mobile and tablet behavior is best-effort and is not guaranteed to expose every workflow optimally.
+- Initial installation uses a one-time first-Admin bootstrap. Later account creation and password recovery depend on a tested SMTP configuration.
+- Admins may preview and import Vietnamese holiday candidates from HolidayAPI, while the stored Admin decision remains authoritative. Manual calendar management remains available.
+- Mentors review global leave and correction queues and separately oversee only the Projects they own.
+- Reports cover attendance/compliance and Project/Task progress in HTML, Excel, and PDF from one shared dataset definition.
+- The authoritative requirements are currently a review draft. Product-context initialization does not authorize application implementation or promote the review DDL into Flyway.
+
+## Capabilities and Constraints
+
+- Global account roles are exactly `ADMIN`, `MENTOR`, and `INTERN`, and are immutable after account creation.
+- Project membership is many-to-many and interval-based. The owning Mentor may add/remove directly and makes every exit decision; the current Leader may invite; only the intended authenticated Intern may accept/decline; members may request but cannot unilaterally leave.
+- Every `PLANNED` or `ACTIVE` Project has exactly one current Intern Leader. Any active member may create a Task assigned only to themselves; only the current Leader may create for another member or reassign broader Task work.
+- Each Task has one current assignee. Only that assignee changes its status and records work.
+- Attendance uses server-time check-in and checkout. Effective-dated policy stores separate check-in and checkout grace periods, both defaulting to 30 minutes; with the default 15:30 end, normal checkout closes immediately after the inclusive 16:00:00 cutoff. Task work is a separate dated-minute record and never proves attendance.
+- Leave is full-day. Only frozen eligible workdays consume quota, and pending or approved requests reserve it.
+- Corrections apply only to missing checkout after the attendance row's historical checkout cutoff. Submission remains open through scheduled end plus 24 hours, and the Mentor then receives a separate 24-hour decision window.
+- Global attendance policy is effective-dated; historical attendance and leave allocations must not drift after later policy or calendar changes.
+- SMTP and HolidayAPI secrets are Admin-managed and encrypted with a deployment-provided master key. Email-dependent account actions fail closed when SMTP is unavailable; other domain actions retain in-app delivery.
+- HTML, Excel, and PDF reports must agree on the same hand-checkable totals and render undefined denominators as `N/A`.
+- The product language is English in v1. Displayed business dates use `dd/MM/yyyy` and times use 24-hour local time.
+- Features absent from the reviewed requirements are not silently in scope.
+
+## Brand Commitments
+
+- The working product name is **Lab Timesheet & Project Management System**, shortened to **Lab Timesheet** where space is constrained.
+- The supplied Vercel/shadcn-style operations-shell images are illustrative references for a compact permission-aware application shell with supported light and dark modes. They do not define fields, workflows, authorization, or persistence and never override numbered requirements or reviewed DDL.
+- Interface copy must be direct, operational, and honest about permissions, deadlines, destructive consequences, unavailable integrations, and illustrative data.
+
+## Evidence on Hand
+
+- `labtimesheet-docs-hub/requirements-specification.md` is the authoritative requirements review draft.
+- `labtimesheet-docs-hub/database-schema.sql` is the companion PostgreSQL design baseline, not yet a production migration.
+- `labtimesheet-docs-hub/assets/ui-reference-light.png`, `ui-reference-dark-shell.png`, and `ui-reference-dark-dashboard.png` are the supplied visual references.
+- The repository contains an early Spring Boot scaffold matching the recorded Java/Spring/Maven direction but no implemented product interface yet.
+- No production data, customer testimonials, adoption metrics, institutional endorsements, or performance claims are available. Future design work must not fabricate them.
+
+## Product Principles
+
+1. **Authorization follows stored context.** Global role alone is insufficient; ownership, membership, leadership, assignment, lifecycle, and record scope determine access.
+2. **History does not move.** Later policy, calendar, membership, invitation, exit decision, leadership, assignment, or assignee changes must not silently rewrite past results, Task creator attribution, or provenance.
+3. **Attendance and Project work stay distinct.** The product may report them together, but one never derives or proves the other.
+4. **Deadlines are enforced at every path.** Scheduled workers improve timeliness, while request-time guards preserve correctness when scheduling is late.
+5. **Prefer explicit, reviewable operations.** Feature-owned controller/service/repository flows, constrained state transitions, focused integrations, and shared report datasets serve clarity over speculative machinery.
+6. **Fixes preserve branch ownership.** A targeted repair uses a clean `work/fix/<feature>/<what-fix>` branch from verified `main`, not `work/<feature>/fix/<what-fix>`; persistent `work/<feature>` refs already occupy that Git ref prefix.
+
+## Accessibility & Inclusion
+
+- The web interface must meet WCAG 2.2 AA contrast and interaction requirements in both light and dark themes.
+- Controls require associated labels or accessible names, visible keyboard focus, keyboard operation, and adequate target sizes.
+- Status and validation cannot depend on color alone. Forms retain safe input, identify field errors, and provide an error summary.
+- Charts are supplemental: every canvas requires an accessible label and an adjacent textual or tabular alternative.
+- Desktop navigation and data tables must remain fully operable without page-level horizontal overflow. Mobile and tablet layouts should avoid preventable breakage on a best-effort basis but are not a fully supported v1 target.

+# Access, Navigation, Icon, and Intern Picker Fix Plan
+
+## Scope
+
+Record the durable workflow for the targeted fixes in this plan. This plan does
+not change product behavior, dependencies, schemas, or the five persistent
+feature-branch ownership areas.
+
+## Implementation steps
+
+1. Prove RED: the contributor guides lack the realizable repair-branch name.
+2. Add one branch rule to contributor guides, design records, plans, and tracked
+   coordination authority: `work/fix/<feature>/<what-fix>` from verified
+   `main`.
+3. State why `work/<feature>/fix/<what-fix>` is invalid while its persistent
+   `work/<feature>` ref exists.
+
+Every targeted repair starts from the taskmaster-verified latest `main`, uses TDD RED → GREEN, adds Javadoc during implementation, records companion evidence, undergoes independent review, and uses a normal, non-force merge only when separately authorized.
+
+4. Regenerate the local SRS after amending the existing operational requirement;
+   do not add a requirement ID or a use case.
+5. Prove GREEN with the executable six-guide regression that independently
+   rejects a positive nested-form recommendation in every guide,
+   coordination-authority consistency, requirement/use-case counts, local-link
+   resolution, and an immutable base-to-candidate whitespace check. Commit the
+   tracked guidance locally; do not push or merge.
+
+## Exit criteria
+
+- The tracked guides, design record, implementation plan, root coordination
+  authority, and evidence record agree on the same repair-branch spelling.
+- The local authoritative, explained, simple, and generated SRS catalogues keep
+  exactly 260 unique requirement IDs and the SRS keeps 14 use cases.
+- The forbidden nested form is documented only as forbidden, not as a usable
+  branch name.

+# Design Record: Durable Fix-Branch Workflow
+
+- **Date:** 2026-08-15
+- **Status:** Accepted
+- **Related plan:** [Access, Navigation, Icon, and Intern Picker Fix Plan](../plans/2026-08-15-access-navigation-icon-intern-picker.md)
+
+## Context
+
+The repository keeps five persistent feature refs: `work/platform`,
+`work/projects`, `work/tasks`, `work/attendance`, and `work/reports-ui`.
+A proposed nested repair name such as `work/platform/fix/example` cannot coexist
+with the existing `work/platform` ref because Git cannot use one ref as both a
+leaf and a prefix.
+
+## Decision
+
+Use `work/fix/<feature>/<what-fix>` for each targeted repair. Create its clean,
+isolated worktree from the taskmaster-verified current `main`. The `<feature>`
+segment identifies the owning persistent area; it does not nest below that
+persistent branch.
+
+The forbidden form is `work/<feature>/fix/<what-fix>`. A repair owner preserves
+other worktrees, records RED and GREEN evidence, commits locally, and does not
+push or merge without separate authority.
+
+Every targeted repair starts from the taskmaster-verified latest `main`, uses TDD RED → GREEN, adds Javadoc during implementation, records companion evidence, undergoes independent review, and uses a normal, non-force merge only when separately authorized.
+
+## Consequences
+
+- Persistent feature branches remain available for their iteration ownership.
+- A repair can be reviewed and handed off as one immutable branch head.
+- Contributor documentation, local coordination authority, and generated SRS
+  traceability use the same spelling.
+
+## Validation
+
+The executable documentation validator checks the exact approved statement in
+each of the six tracked guides and independently rejects an injected positive
+nested-branch recommendation in every guide. The copied root coordination
+authority uses the same rule and is checked separately for consistency. The
+evidence record also verifies requirement counts, generated SRS use-case count,
+and local Markdown links.

+# Test Evidence: development-profile attendance policy time hydration

+- **Test type:** Integration
+- **Requirement IDs:** `ATT-002`, `ATT-003`, `I1-ATT-01`
+- **Scenario IDs:** `AC-ATT-001`
+- **Test class/method:** `com.lab.labtimesheet.feature.attendance.controller.CalendarDevelopmentProfileWebIntegrationTest#v1SeededPolicyLetsFormAuthenticatedAdminOpenCalendarInAsiaHoChiMinhDevelopmentProfile`
+- **Implementation commit:** pending
+
+## Protected behavior
+
+The unmodified V1 attendance policy must hydrate its `time` schedule as the configured local wall-clock values when the development profile runs in `Asia/Ho_Chi_Minh`. A form-authenticated Admin can therefore open the calendar without weakening the policy rule that requires the checkout cutoff to be before local midnight.
+
+## Test method
+
+The test starts the application with the real `dev` profile plus isolated test configuration, forces the JVM default zone to `Asia/Ho_Chi_Minh` before JPA starts, and uses PostgreSQL 18.4 Testcontainers with Flyway V1. It bootstraps an Admin through the form, logs in through the form, and requests `/attendance/calendar`, which resolves the current policy through `AttendanceApplicationService.currentBusinessDate`.
+
+## Hand-derived expected result
+
+V1 explicitly stores `scheduled_start = 08:30`, `scheduled_end = 15:30`, and `checkout_grace_minutes = 30`. The checkout cutoff is therefore `16:00`, which is strictly before local midnight, so the calendar request returns HTTP 200.

+dispatch or by a push to `main`. Every third-party workflow action is pinned to
+the reviewed latest release commit rather than a moving tag.
+
+## Test method
+
+The dependency-free delivery contract reads both workflow files and checks the
+Testcontainers host override, event filters, verify-to-build dependencies, and
+the complete allowlist of immutable action SHAs. The remote failure log supplies
+the production-shaped network reproduction because it ran inside the real Gitea
+Docker runner.
+
+## Hand-derived expected result
+
+The runner already resolves `host.docker.internal` to its Docker host. Therefore
+Testcontainers must use that host instead of the job-network gateway

+- **Implementation commit:** e70159a81b6445825f6d5f912ecf3c4aa3c1aa85
+
+## 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
+
+The production image runs as a non-root Java 25 process, exposes health probes, and accepts the same environment-backed datasource configuration with either the optional PostgreSQL 18.4 Compose sidecar or an external database. Gitea verifies every pull request and push, publishes immutable SHA plus `main` image tags only from `main`, and skips native ARM64 work unless the matching runner is explicitly available.
+
+## Test method
+
+The existing PostgreSQL-backed bootstrap integration test requests the liveness and readiness endpoints before initialization. A dependency-free Node contract checks the deployment files for the required runtime, Compose, trigger, permission, publication, and optional-runner boundaries. Docker and Compose validation then exercise the real build and both database topologies.
+
+## Hand-derived expected result
+
+An absent ARM runner must skip the ARM job without blocking AMD64 publication. Enabling the runner creates an ARM64 architecture tag and a combined manifest, while the canonical SHA and `main` tags remain valid AMD64 images when ARM is disabled. Compose must preserve PostgreSQL data in a named volume and must not require the bundled database when an external JDBC URL is supplied.

+- **Implementation commit:** `a9fb9487692e84f5a7e7923570cbded58c362a2f`
+
+## Protected behavior
+
+The executable entry point replaces the legacy Windows JVM timezone ID `Asia/Saigon` with the canonical business timezone ID `Asia/Ho_Chi_Minh` before pgJDBC opens a PostgreSQL connection. Other supported operating-system timezone IDs remain unchanged.
+
+## Test method
+
+The entry-point test replaces Spring startup with Mockito's existing static test seam, invokes the real `main` method with a legacy JVM default, and checks that normalization happens before Spring starts. The PostgreSQL test starts a real PostgreSQL 18.4 Testcontainer, proves pgJDBC 42.7.11 is rejected while the JVM default is `Asia/Saigon`, invokes the same startup normalization, and then opens a valid JDBC connection. A negative test verifies that an unrelated supported timezone is not overwritten.
+
+## Hand-derived expected result
+
+PostgreSQL does not accept `Asia/Saigon` as a startup `TimeZone`, while the approved business timezone is `Asia/Ho_Chi_Minh`. Therefore only the legacy alias is replaced, the following connection succeeds, and a supported non-Vietnam timezone remains unchanged.

+A local Java 25 process was also started with `-Duser.timezone=Asia/Saigon` against a disposable PostgreSQL 18.4 database on port `55439`. Hikari connected, Flyway migrated the fresh database, Tomcat started on port `18080`, and Spring reported `Started LabtimesheetApplication`. The process shut down cleanly and the disposable database container was removed.
+
+## External-test boundaries
+
+The regression executes the installed pgJDBC version against PostgreSQL 18.4 and reproduces the exact rejected timezone value from the Windows report. It does not run the Windows JVM itself; the supplied Windows log is the evidence that its OS/JDK mapping produced `Asia/Saigon`.

+## 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. 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 branch statement and complete targeted-repair lifecycle in
+each of the six guides. Its self-test independently removes each of the six
+lifecycle elements from every guide and asserts the file-specific rejection. It
+also retains a fresh positive nested-branch mutation for every guide. The copied
+root coordination files are compared byte-for-byte with their main-root sources
+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
+artifact's exact approved statement. Each independent simulated positive
+nested-branch recommendation must fail. The three tracked coordination files
+must exactly match the authorized main-root versions. Loss of any lifecycle
+element from any guide must fail. The existing SRS generator must still report
+260 requirements and 14 use cases.

+- **Implementation commit:** `82ad8202fd31f77db8c3932a902dba07cee70894`
+
+## Protected behavior
+
+Attendance uses the installed Lombok processor only for mechanical constructors while preserving the compiled API:
+package-level Spring injection, protected JPA construction, immutable record components, domain constructors and
+mutations, raw punch and attached-policy history rules, composite-key identity, and existing public method names.
+
+## Test method
+
+Reflection inspects compiled `feature.attendance` classes rather than source spelling. It verifies every constructor's
+parameter order and modifier, every immutable model's record components, and the exact public/protected declared method
+surface of each Attendance entity. The entity surface prevents generated bean getters/setters or entity
+`equals`/`hashCode`/`toString` widening while explicitly retaining `AttendanceRecordEntity#setCheckOutAt` and the
+`LeaveRequestDayId` identity methods. Exact controller and service surfaces likewise prevent Lombok from exposing
+collaborator getters/setters or generated `equals`/`hashCode`/`toString` methods.
+
+## Hand-derived expected result
+
+Five injection-only components expose only their package-scoped dependency constructors. Six JPA/embeddable types
+retain protected no-argument construction alongside their intentional domain constructors, and the stateless domain
+service remains package-scoped. Seven immutable models remain records with the same component order and types. Entity
+method surfaces contain only intentional domain conversion/access/mutation methods; only the composite key owns
+`equals` and `hashCode`, and no Attendance entity declares `toString`. Both controllers and all four Attendance
+services expose only their existing route or application/domain operations, never their injected collaborators.

+
+## Protected behavior
+
+Platform-owned Spring collaborators, request forms, and JPA entities must not retain eligible handwritten
+dependency-assignment constructors, trivial accessors, or empty persistence constructors. The retrofit must preserve
+constructor visibility, form normalization, entity encapsulation, defensive copies of credential/token bytes, and all
+account, authentication, SMTP, and cross-feature behavior.
+
+## Test method
+
+The source audit searches only the 79 members classified as mechanical after reading every root/config,
+`feature.account`, and `feature.integration` production type. It deliberately excludes normalized email/display-name
+setters, defensive byte-array getters, domain constructors and factories, state transitions, the normalized
+`AccountService` public-origin constructor, `SecretCipher` key construction, and the two-constructor JavaMail test
+seam. No permanent annotation-presence test was added because annotations are an implementation detail; compilation
+and production-shaped tests protect the real contracts.
+
+## Hand-derived expected result
+
+Before the retrofit the audit must find 79 eligible handwritten members and exit 1. After targeted Lombok generation,
+the same audit must find none and exit 0, while the retained non-mechanical members remain explicit.

+
+## Protected behavior
+
+Project Spring components use targeted required-argument constructor generation only when their
+constructors assign required final dependencies. Project JPA entities use only protected no-arg
+constructor generation. Records remain records, and entity identity, lazy associations, explicit
+domain accessors, aggregate constructors, and mutation methods do not gain broad generated APIs.
+
+## Temporary RED/GREEN method
+
+The temporary source-contract test inspected only `feature.project` production sources. It required
+`@RequiredArgsConstructor` on the three injection-only components, removal of the stateless advice's
+handwritten no-arg constructor, and protected `@NoArgsConstructor` on the three JPA entities. It also
+rejected broad entity Lombok annotations, confirmed representative explicit domain APIs remained,
+and verified every Project immutable DTO/value type remained a Java record. It was deleted after
+preserving the historical RED/GREEN below because exact imports, annotation spelling, and source
+substrings are implementation details rather than a durable public contract.
+
+## Hand-derived expected result
+
+Seven handwritten constructors are mechanical and eligible for removal: three dependency-assignment
+constructors, one empty advice constructor, and three empty protected JPA constructors. The three
+entity domain constructors, all aggregate mutation methods, defensive-copy accessors, derived
+membership/leadership accessors, validation constructors, exception constructors, and all thirteen
+records must remain explicit or remain records because they carry behavior or preserve the existing
+API shape.

+- **Implementation commit:** `e2b206c27e494fbcd0cc3ed99ff8c2c470285f9e`
+
+## Protected behavior
+
+Reporting uses Lombok only for constructors that mechanically assign required Spring dependencies. Immutable dashboard DTOs remain records, the access-denied exception keeps its explicit superclass constructor, and the attendance-state presentation contract keeps its explicit fluent `label()` method.
+
+## Test method
+
+The narrow source audit reads only the four Reporting production sources. It requires `@RequiredArgsConstructor` and removal of the two injection-only constructors while positively checking the deliberately retained records, exception constructor, and presentation method. A temporary JUnit source test established RED and passed GREEN, then was removed because retaining exact source-string assertions would couple the suite to implementation details. Existing unit, MockMvc, and architecture tests compile and exercise the generated constructor API.
+
+## Hand-derived expected result
+
+`DashboardController` and `DashboardService` each contain final injected dependencies and constructors that only assign those fields, so both are eligible for `@RequiredArgsConstructor`. `DashboardAccessDeniedException(String)` must call its superclass and exposes a documented public error contract. The dashboard projections are already concise immutable records. `AttendanceState.label()` intentionally exposes a fluent presentation API rather than Lombok's default `getLabel()` shape.

+## External-test boundaries
+
+The source audit proves annotation scope and deliberate retention but does not alone prove generated bytecode, Spring injection, dashboard behavior, or Thymeleaf property access. Compile, Reporting service tests, MockMvc dashboard tests, architecture tests, PostgreSQL role-dashboard integration, and Javadoc/doclint provide those gates. Reporting owns no JPA entity or mutable bean, so JPA accessor/mapping checks are outside this feature's retrofit scope. Java 25 reports Lombok's known `sun.misc.Unsafe` annotation-processor warning, and Mockito reports its dynamic-agent warning; neither changed or failed the executed gates.

+# Test Evidence: Task Lombok boilerplate retrofit

+- **Test type:** Unit

+- **Scenario IDs:** `AC-TSK-001`–`AC-TSK-006`, `AC-TSK-010`
+- **Test class/method:** Source audit plus existing Task unit, web, and PostgreSQL integration suites
+- **Implementation commit:** `7c1a26d`
+
+## Protected behavior
+
+The Task feature uses the configured Lombok processor for mechanical dependency-injection constructors, JPA no-argument constructors, and existing entity getters. Explicit Task constructors and mutation methods remain responsible for initial state, attribution, timestamps, and workflow invariants. The retrofit must not add entity equality, hash, string, or setter behavior and must not alter the existing public getter contract.
+
+## Test method
+
+The source audit counts the eligible handwritten constructors and getter methods before and after the retrofit. Existing Task tests then exercise Spring injection, MVC binding, JPA materialization, entity getters, authorization, status transitions, comments, and Project/attendance boundaries through the same public behavior used before the source-only change.
+
+## Hand-derived expected result
+
+Four Spring components have injection-only constructors, so all four may use `@RequiredArgsConstructor`. `Task` and `TaskComment` need protected JPA no-argument constructors and may use targeted Lombok generation. The 17 existing entity getters may be generated, but `Task.deletedByMembershipId`, `Task.updatedAt`, and `Task.version` must remain without newly exposed getters. Domain constructors and `Task.changeStatus` must remain explicit.

+
+## 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.

+## Behavior under test
+
+Project creation, direct member addition, and leadership reassignment render only server-provided eligible Intern choices. The native dialog picker exposes name, student code, and internship dates while numeric identifiers remain form values rather than visible labels. Local search, selection summaries, focus, apply, cancel, empty results, and retained server errors remain usable without adding a client API.
+
+## Expected result derivation
+
+The expected options are literal fixtures from the Account public DTO. Project membership history independently determines which eligible users are valid nonmembers or current-member leadership candidates. Native dialog controls keep server forms and CSRF as the mutation boundary.
+
+## RED
+
+`env PATH=/opt/homebrew/opt/node@24/bin:$PATH npm run test:ui` executed the dependency-free interaction contract first: 1 test, 1 failure. Opening the picker left `dialog.open` undefined because no picker behavior existed.
+
+The combined Java RED command was `env JAVA_HOME=/opt/homebrew/opt/openjdk@25 PATH=/opt/homebrew/opt/openjdk@25/bin:$PATH ./mvnw '-Dtest=ProjectControllerTest,ProjectServiceIntegrationTest' test`. After correcting test-only assertion imports, test compilation failed only because the requested `ProjectService.addMembers(long,long,List<Long>)` API did not exist. Controller rendering RED will be rerun after that producer API compiles.
+
+After the producer API compiled, `env JAVA_HOME=/opt/homebrew/opt/openjdk@25 PATH=/opt/homebrew/opt/openjdk@25/bin:$PATH ./mvnw '-Dtest=ProjectControllerTest' test` ran 19 tests with 4 expected assertion failures for the missing eligible-option model, filtered multi-select markup, and retained selection rendering. A separate no-roster regression ran 1 test with 1 assertion failure because the disabled picker trigger had no reachable explanatory copy.
+
+Independent review added rendered regressions before the correction. The same focused controller command ran 22 tests with exactly 3 failures and no errors: both closed-dialog radio contracts detected browser `required`, and stale batch recovery lacked the count-only replacement message. The new missing-selection POST contracts already passed through server Bean Validation.
+

+
+After the review correction, the focused controller command passed 22/22. Creation and leadership radios no longer use closed-dialog browser constraint validation; missing selections re-render their server field errors.

+
+## External boundaries
+
+No browser loop or Impeccable detector is run on this branch; the root owner performs one integrated pass. MockMvc proves rendered semantics and a dependency-free Node test executes the dialog/search/selection behavior with controlled DOM boundaries.
+
+After merging exact reviewed `main` `32c8a2d315d2175760c5d4792988cd0aa5ab6dd0`, `npm ci`, the 1/1 UI test, frontend build, compile, Project-scoped Javadoc/doclint, and diff check all succeeded. The first affected Java command added the updated shared `UiContractWebTest` and passed 45/45 tests with no failures, errors, or skips.
+
+The bounded post-review affected command reran `ProjectControllerTest,ProjectEntityTest,ProjectPersistenceStructureTest,ProjectServiceIntegrationTest,ProjectTaskMutationContextTest,LayerStructureTest,UiContractWebTest` and passed 47/47 with no failures, errors, or skips, including 9/9 Project service tests against PostgreSQL 18.4. The UI test remained 1/1; frontend build, compile, Project-scoped Javadoc/doclint, and `git diff --check` also succeeded.
+
+The root-owned final full suite then exposed a branch-induced MVC-slice fixture RED: 213 tests ran with 0 failures and 3 errors, all `ProjectTaskFormAccessibilityWebTest` context errors because the slice did not provide the new ProjectController AccountService dependency. A focused reproduction ran the class at 3 tests, 0 failures, 3 errors and reported the same missing AccountService constructor dependency.
+
+The smallest test-only correction supplies the controller's AccountService and Clock dependencies and the existing ProjectQueryService mock's authenticated Mentor response. The intermediate focused runs exposed each dependency in order; no production code changed. Final focused GREEN: `env JAVA_HOME=/opt/homebrew/opt/openjdk@25 PATH=/opt/homebrew/opt/openjdk@25/bin:$PATH ./mvnw '-Dtest=ProjectTaskFormAccessibilityWebTest' test` passed 3/3 with no failures, errors, or skips. The root owner retains the broader rerun.

+# 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.

+## External-test boundaries
+
+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.
