+# Password Manager Project Plan
+
+## Purpose
+
+Schedule the three gateways that take the password manager from an empty
+repository to a published, tested and documented project. The Business Case
+sets no deadline, so the plan keeps the phases short and sequential.
+
+## Planning Assumptions
+
+- Work starts 2026-10-14 and the plan ends 2026-10-19.
+- Each phase is one branch and one pull request, and its tasks are Issues.
+- S01 reviews every artifact; in autonomous mode the AI acts as stand-in for S01
+  and the review records say so ([SA-001]).
+- Product Owner language is English (domain `it`); the wiki exists in English,
+  Danish and Bahasa Malaysia as the Business Case requires ([BC-001]).
+- The application is a user interface, so the presentation pattern is MVVM.
+  The wireframe is the course's layout: logo on top, then Website with a
+  Search button, Email/Username, Password with a Generate button, and a wide
+  Add button.
+
+## Gateway Schedule
+
+| Gateway | Document | Window | Decision date | Owner | Stories | Main deliverable | Milestone |
+| --- | --- | --- | --- | --- | --- | --- | --- |
+| Project Foundation | [MIL-001] | 2026-10-14 to 2026-10-15 | 2026-10-15 | S01 | none | pyproject.toml, .gitignore, constants.py, Doxyfile, README, repository description and topics | |
+| Password Manager Features | [MIL-002] | 2026-10-15 to 2026-10-17 | 2026-10-17 | S01 | none | JSON storage, exception handling, search, generator, window and tests | |
+| Documentation and Publishing | [MIL-003] | 2026-10-17 to 2026-10-19 | 2026-10-19 | S01 | none | Screenshots, README with screenshots, wiki in en, da and ms | |

+## Scope Coverage
+
+| Business Case scope item | Gateway |
+| --- | --- |
+| Password generation, saving to JSON, searching by website | [MIL-002] |
+| Exception handling for a missing, empty or invalid data file | [MIL-002] |
+| A Tkinter window with the assignment's fields and buttons | [MIL-002] |
+| `pyproject.toml`, pytest tests, `constants.py`, `.gitignore`, Doxyfile, Doxygen comments | [MIL-001] and [MIL-002] |
+| README | [MIL-001], completed with screenshots in [MIL-003] |
+| Wiki in English, Danish and Bahasa Malaysia, screenshots | [MIL-003] |
+| Repository description and topics | [MIL-001] |
+| Local `.venv` and pip upgrade instructions | [MIL-001] |
+
+## Dependencies
+
+```
+MIL-001 -> MIL-002 -> MIL-003
+```
+
+A No-Go on a gateway holds every later gateway; the later dates move by the
+rework time.
+
+## Plan Risks
+
+| Risk | Impact | Mitigation |
+| --- | --- | --- |
+| The git host token cannot edit repository metadata or merge | Description, topics or merge steps fail | Stop and report as autonomous mode requires; the user performs the step |
+| Screenshots cannot be captured in the session | README and wiki lack images | Capture the window with a documented script; if impossible, stop and report |
+| The wiki publish workflow has no runner | Wiki does not reach the host | The pages stay in `docs/wiki/`; report and let the user decide how to publish |
+
+## Open Issues
+
+- No use cases or user stories are modelled: the tasks are technical steps of
+  the course assignment, so every task is a plain task.
+- The Domain Dictionary (`DICT`) is created with the first milestone review so
+  that the language checklist can be applied.
