## Purpose

This plan schedules the five phases that deliver the Day 40 flight club (see [BC-001]) in a two-week window. One branch and one pull request per milestone keep track of the steps.

## Planning Assumptions

- The plan starts 2026-10-24 and ends by 2026-11-07.
- Each phase ends in a pull request that closes its issues; the Product Owner is S01 ([SA-001]).
- Autonomous mode: after the user accepts this plan, the AI creates, reviews as stand-in for S01, commits and merges each phase.
- Tests never use the real `.env`, the network, SMTP or the WhatsApp session.

## Gateway Schedule

| Gateway | Document | Window | Decision date | Owner | Stories | Main deliverable | Milestone |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Baseline and project setup | [MIL-001] | 2026-10-24 to 2026-10-26 | 2026-10-26 | S01 | none | Project skeleton, Day 39 code base, CI, repository metadata | |
| Flight data and indirect search | [MIL-002] | 2026-10-26 to 2026-10-29 | 2026-10-29 | S01 | none | FlightData.stops, check_flights with is_direct, indirect fallback in main | |
| Customer emails | [MIL-003] | 2026-10-29 to 2026-10-31 | 2026-10-31 | S01 | none | DataManager reads the users sheet and all settings in __init__ | |
| Email notifications and main program | [MIL-004] | 2026-10-31 to 2026-11-04 | 2026-11-04 | S01 | none | NotificationManager.send_emails and the final main flow | |
| Documentation and wiki | [MIL-005] | 2026-11-04 to 2026-11-07 | 2026-11-07 | S01 | none | README, wiki en/da/ms, screenshots | |

## Scope Coverage

| Business Case scope item | Gateway |
| --- | --- |
| Day 39 code carried over, pyproject, constants, .gitignore, Doxyfile, venv | [MIL-001] |
| CI workflows, repository description and topics | [MIL-001] |
| FlightData stops, check_flights with is_direct, indirect fallback | [MIL-002] |
| DataManager.get_customer_emails and settings in __init__ | [MIL-003] |
| NotificationManager.send_emails, direct and stopover messages, main.py | [MIL-004] |
| README, wiki in en/da/ms, screenshots | [MIL-005] |

## Dependencies

```
MIL-001 → MIL-002 → MIL-003 → MIL-004 → MIL-005
```

A No-Go on a phase moves every later date by the rework time.

## Plan Risks

| Risk | Impact | Mitigation |
| --- | --- | --- |
| CI workflows need changes or a runner the host lacks | MIL-001 slips | Install only fitting workflows; stop and report after three failed fixes |
| Screenshots cannot be captured without real data | MIL-005 slips | Use mock data and a test run only |
| SMTP values are missing from the local `.env` | Real mails cannot be sent | Tests use fakes; the participant adds the values before a real run |

## Open Issues

- The local `.env` has no SMTP address, email address or app password, and no "users" sheet endpoint; they are needed only for a real run, not for the build or the tests.
- The users sheet column names are assumed to be `firstName`, `lastName` and `email` (Sheety camel-cases the Google Form headings); the participant can correct them before acceptance.
- The lesson's starter zip uses Twilio; this project keeps the Day 39 `pywhatkit` WhatsApp delivery instead, as the Business Case records.
