Purpose

This gate decides whether the repository has the files that carry no program logic yet: configuration, ignore rules, constants, README, source documentation settings, the continuous integration workflow, and the repository description and topics. The work is delivered on the branch mil-001-project-foundation and one pull request.

Deliverable

pyproject.toml, the Python .gitignore, the package src/weather/ with __init__.py and constants.py, tests/test_constants.py, README.md following the Product Owner's template, Doxyfile, and .gitea/workflows/ci.yml. The repository description and topics on the git host are set.

Proposed repository description and topics, for S01 to confirm by accepting the plan:

• Description: "Reading CSV weather data in Python with the csv library and pandas, day 25 of Udemy's 100 Days of Code bootcamp: DataFrame and Series, average, maximum, row selection, create and export. pytest tests, Doxygen docs, no runtime dependencies for the csv part."
• Topics: 100-days-of-code, csv, data-analysis, doxygen, education, pandas, pytest, python, python-bootcamp, udemy.

Go / No-Go Criteria

#	Criterion (objectively checkable)	Go	No-Go
1	In a fresh clone, python -m venv .venv, python -m pip install --upgrade pip and python -m pip install -e ".[dev]" succeed in Windows PowerShell	All three commands exit 0	Any command fails
2	pytest runs	Exit code 0, at least one test of constants.py	Failing test, or no test of constants.py
3	pyproject.toml states the Python version and the dependencies	requires-python = ">=3.13", dependencies = [], an extra pandas, a dev extra with pytest, ruff, mypy and pandas, and a repository URL that names this repository	Any of the four is missing or different
4	The .gitignore protects local files	git check-ignore .venv .env __pycache__ build lists all four	One of them is not ignored
5	constants.py holds the file names and the Fahrenheit factors with Doxygen comments	Every value is an UPPER_SNAKE constant with a Doxygen comment	A value is missing or has no Doxygen comment
6	doxygen Doxyfile builds the source documentation	Ends with 0 warnings and writes HTML for src/	Any warning, or no output
7	The README follows the Product Owner's template	Every section title of the template in the given order (Requirements, Set up with Windows powershell, Linux debian and MacOS, Run, Run the tests, Continuous integration, Build the source documentation, Project layout, License), with commands for the three systems	A heading is missing or out of order, or a section has no commands
8	The CI workflow exists	.gitea/workflows/ci.yml installs .[dev] and runs pytest, ruff and mypy on Python 3.13, and nothing under .github/workflows exists	No workflow, or it does not run the tests, or a file exists under .github/workflows
9	The repository page is complete	Description is non-empty and there are at least 5 topics on the git host	Description empty or fewer than 5 topics
10	The code is reviewed	RC-* against QC-PY-001 has the verdict Go	Verdict No-Go or Go-with-conditions
11	No secret is in the change	.env is not tracked and no token appears in any changed file	A token is found in the diff

Dependencies

Depends on	Reason
PP-001 accepted	The plan schedules this gateway; the plan-first gate needs it before any code
This milestone accepted with a Go review	The plan-first gate allows no file under src/ or tests/ before that

Traceability

Business Case objective / KPI / user story	Reference
Objective 9: reproducible environment, csv part without dependencies	BC-001, criteria 8 and 10 in Success Criteria
Objective 10: tests with temporary files	BC-001, criterion 7 in Success Criteria
Objective 11: Doxygen and README	BC-001, criteria 8 and 9 in Success Criteria
Objective 13: repository page	BC-001, criterion 12 in Success Criteria
Objective 12: traceable steps	BC-001, criterion 11 in Success Criteria

Target Date

2026-10-15 — first of five gateways, inside the plan of PP-001 that ends 2026-10-23.

Tasks

#	Task	Summary	Needs its own Use Case/User Story?	Reference
1	Add pyproject.toml for the Day 25 weather repository	Create pyproject.toml for the project weather: requires-python = ">=3.13", an empty dependencies list, an optional extra pandas, a dev extra with pytest, ruff, mypy and pandas, the src layout for the package weather, the pytest settings, and a description and repository URL that name this repository and day 25. Serves objective 9.	No
2	Add the Python .gitignore for the Day 25 weather repository	Add the Python .gitignore: bytecode, .venv/, build and packaging output, pytest, ruff, mypy and Doxygen caches. It also ignores .env, so the personal tokens can never be committed.	No
3	Add constants.py and its test	Create src/weather/__init__.py, src/weather/constants.py and tests/test_constants.py. Every value (the data file name, the column names, the Fahrenheit factors, the export file name) is an UPPER_SNAKE constant with a Doxygen comment. Serves objective 8.	No
4	Add the README for the Day 25 weather repository	Write README.md in the Product Owner's template. Document creating a local .venv, python -m pip install --upgrade pip and python -m pip install -e ".[dev]", with Windows PowerShell, Linux Debian (Debian 13 or newer) and macOS. The Run section is finished in MIL-005. Serves S02 and S03.	No
5	Add the Doxyfile for the Day 25 weather repository	Add a Doxyfile that reads src/, writes to build/doxygen, extracts documentation for Python and treats warnings as failures; the project brief names day 25.	No
6	Add the continuous integration workflow	Add .gitea/workflows/ci.yml: check out, set up Python 3.13, upgrade pip, install .[dev], run pytest, ruff and mypy. The file stays in .gitea/workflows, not .github/workflows.	No
7	Set the repository description and topics	Set the description and at least 5 topics of this repository on the git host with the Gitea application programming interface (API), using GITEA_TOKEN from the personal .env file; the file is only read by the command, never imported, tested or tracked. Use the proposed text of the Deliverable section. Serves S03 and objective 13.	No
