Purpose
This plan schedules the seven milestones of the Musical Time Machine project inside the Business Case window of 2026-10-28 to 2026-11-30 (BC-001, Constraints).
Planning Assumptions
- Week 1 starts 2026-10-28; the plan ends by 2026-11-30, per the Business Case constraint.
- One milestone is one branch and one pull request; a milestone is as long as its tasks need, between 4 and 9 days.
- Reviews are done by the AI as stand-in for S01 (SA-001, S01); the language criteria of
QC-LANG-001 that need a person stay open until S01 confirms them.
- Live steps 2 to 4 need S01's
browser.json; the dates of MIL-004 to MIL-006 assume it exists by 2026-11-14.

Plan Risks
| Risk |
Impact |
Mitigation |
browser.json not available by 2026-11-14 |
MIL-004 to MIL-006 cannot be closed |
The run stops and reports; tests with fakes are finished so only the live screenshots wait |
| Language criteria need a person |
Baseline stays Go-with-conditions |
Ask S01 to confirm criteria 3, 5 and 9 of QC-LANG-001 when accepting the plan |
| Bakeboard offline during the live run |
Step 1 screenshot delayed |
The stored fixture proves the code; the screenshot is taken later |
Open Issues
- The owner of the repository on the git host: the
origin remote uses Tirsvad-Udemy-100-days-of-code, the request names Tirsvad-Udemy-100_days_of_code; the remote is used until S01 says otherwise.
- Whether the live steps 2 to 4 can be run depends on
browser.json from S01.
