Purpose

This plan schedules the three phases of the Hirst painting project, the colour palette, the spot painting and the visible colours, inside the one-week limit that BC-001 sets (2026-10-07 to 2026-10-14). Each phase is a gateway with its own milestone document, and each gateway ends with a Go/No-Go decision by S01.

Planning Assumptions

• Week 1 starts 2026-10-07; the plan ends by 2026-10-14, per the Business Case assumption confirmed by S01.
• The baseline documents (BC-001, SA-001 and their review records) are finished on 2026-10-07, before the first phase starts.
• Phase length: two to five days, because the work is one small script. The palette phase is shorter because it is the smaller of the two.
• S01 owns every phase and takes every Go/No-Go decision; S01 is the only stakeholder in SA-001, so communication follows the review gates in that document.
• MIL-003 was added on 2026-10-08, after MIL-001 and MIL-002 had been decided Go, to meet objective O6 of BC-001; it runs from 2026-10-08 to 2026-10-10, inside the one-week limit.
• No user stories exist: the program has no user interaction beyond the exit click, so the Stories column is empty.

Gateway Schedule

Gateway	Document	Window	Decision date	Owner	Stories	Main deliverable	Milestone
Colour palette	MIL-001	2026-10-07 to 2026-10-09	2026-10-09	S01	none	Palette function that returns the reference image's colours without white shades	MIL-001 milestone
Spot painting	MIL-002	2026-10-10 to 2026-10-14	2026-10-14	S01	none	Program that draws the 10 by 10 painting and meets SC1 to SC7 of BC-001	MIL-002 milestone
Visible colours	MIL-003	2026-10-08 to 2026-10-10	2026-10-10	S01	none	Palette without faint colours: every colour has a contrast of 2.0 or more with white (O6, SC8 of BC-001)

Scope Coverage

Business Case scope item	Gateway
One Python program using turtle, random and colorgram	MIL-001 (colorgram part), MIL-002 (turtle and random part)
Palette extracted from one reference image, white shades removed	MIL-001
Removal of faint colours from the palette: contrast with white below 2.0	MIL-003
Drawing the 10 by 10 dot grid: size, spacing, row change, heading	MIL-002
Screen handling: exitonclick, hidden turtle, pen up, drawing speed	MIL-002
Framework documents and review records for the plan-first workflow	Finished before each gateway (BC-001, SA-001, this plan, the milestone and their reviews); the review of each phase's code is a task in that phase

Dependencies

Baseline documents → [MIL-001] Colour palette → [MIL-002] Spot painting → [MIL-003] Visible colours

MIL-002 needs the palette function from MIL-001. A No-Go on MIL-001 moves the start of MIL-002 by the days needed to rework and re-review; the one-week limit then has no slack, so S01 decides whether to extend it.

MIL-003 extends the palette function of MIL-001 and redraws the painting of MIL-002; both were decided Go on 2026-10-08, so nothing blocks it. A No-Go on MIL-003 leaves the accepted program as it is, so the earlier gateways stand.

Plan Risks

Risk	Impact	Mitigation
The reference image is not supplied before the palette phase starts	MIL-001 cannot start its extraction task; the window of two to three days is lost	The tasks that do not need the image (toolchain check, white filter and its tests) come first; S01 decides on another image if this one stays unavailable
A No-Go on the palette phase	MIL-002 starts late and the one-week limit is missed	The palette phase is the smaller one and ends 2026-10-09, leaving five days for the painting phase
Review effort is large compared with the code	Time goes to documents instead of the program	Two phases, plain tasks, no use cases or design artifacts, as set out in BC-001
The faint-colour filter changes code that MIL-001 and MIL-002 already delivered	An earlier test or criterion, such as SC3, could break	MIL-003 keeps the white-shade filter and its tests untouched and adds the contrast filter beside it; criterion 3 of MIL-003 requires every earlier test to pass
The Project Plan has no quality checklist	The plan is accepted on S01's judgement alone	S01 checks the plan against the one-week limit of BC-001 and the Go/No-Go criteria of both milestones

Open Issues

• Reference image: resolved. S01 supplied assets/20260524_132700.jpg on 2026-10-07, which completed task 4 of MIL-001.
• Project Plan review: the Project Plan has no quality checklist yet, so it is Accepted when S01 says so in chat (done on 2026-10-07, and again on 2026-10-08 for the gateway decisions and for MIL-003); no review record is written for it.
• Milestone links: sync-project.sh --apply ran on 2026-10-07 and created the two Milestones and issues #1 to #13 on the git host; the Milestone column links to them.

Gateway Decisions

The Go/No-Go decision of each gateway, taken by its owner (S01) in chat and recorded here by the assistant. The Decision date in the Gateway Schedule is the planned date; the date below is the actual one.

Gateway	Document	Decision	Decided by	Decision date	Planned date	Basis
Colour palette	MIL-001	Go	S01	2026-10-08	2026-10-09	All five Go criteria met: imports and window, 30 colours, no white shade, 18 tests passing, code review RC-005 with verdict Go. Pull request PR 14 merged; Milestone closed on the git host
Spot painting	MIL-002	Go	S01	2026-10-08	2026-10-14	All six Go criteria met: 100 dots in 10 rows of 10, size 20 and 50 apart, colours from the palette, clean result with the window open until a click, drawn in 0.35 seconds, code review RC-006 with verdict Go. Pull request PR 16 merged; Milestone closed on the git host

Both decisions came before the planned dates because every Go criterion was already met. The two open decisions on RC-006 (the display requirement of the tests and the pale palette colours) did not block either one.
