# 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.
- `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.
## 5. Iteration 2 — Complete business workflows
Iteration 2 starts only after every continuing branch incorporates the integrated Iteration 1 `main`.

### 5.6 Iteration 2 integration gate
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.
- Mentor changes Leader without moving the former Leader's Tasks.
- Member requests to leave and Leader requests removal; Mentor rejects or approves through assisted transfer and required replacement.
- Mentor completes a Project after all non-deleted Tasks are done.
- Ordinary domain actions retain in-app notifications when SMTP is unavailable.
- Full integrated tests pass at the iteration integration commit.
## 6. Iteration 3 — Hardening, reports, and delivery readiness

### 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 |

# 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 |
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.
