Purpose

This plan schedules the four phases that deliver the squirrel census assignment: tooling, analysis, documentation and wiki publication. It schedules them against the Business Case constraint of one pull request per milestone and a single-day effort.

Planning Assumptions

• Week 1 starts 2026-10-13 (the day of the plan); the plan ends by 2026-10-16.
• Phase length: one day per phase.
• One branch and one pull request per milestone, each closing the issues of its tasks (BC-001 Constraints).
• The Product Owner and reviewer is S01 for every phase (SA-001); in autonomous mode the AI acts as stand-in and records it in each review record.
• The plan is accepted by S01 in chat; the Project Plan has no quality control (QC) checklist.

Scope Coverage

Business Case scope item	Gateway
Reading the census file and counting by primary fur colour	G2
Summary table exported as squirrel_count.csv	G2
Command line entry point, constants.py, pyproject.toml, .gitignore, tests, CI	G1 and G2
Doxygen comments, Doxyfile, build instructions	G1 and G3
README, screenshots	G3
Three-language wiki	G4
Repository description and topics	G1 (set) and G4 (verified)

Dependencies

G1 -> G2 -> G3 -> G4

A No-Go at a gateway stops the later gateways; their dates move by the days the rework takes.

Plan Risks

Risk	Impact	Mitigation
CI runner is not available on the git host	The CI workflow cannot be shown green	Run the same commands locally and report the missing runner
Wiki repository cannot be pushed	G4 deliverable is not published	Keep the pages under docs/wiki/ and report it
Doxygen is not installed locally	The documentation build cannot be verified	Report as not verified; document the command

Open Issues

• The repository URL in the request (Tirsvad-Udemy-100_days_of_code) differs from origin (Tirsvad-Udemy-100-days-of-code/025-squirrel); the plan follows origin.
• The census file (730 kilobytes) is assumed to be committed under data/; S01 can veto this at plan acceptance.
• The lecture uses Pandas; the plan uses the standard library to keep zero runtime dependencies (ADR-0001, SA-001 conflict list).
