Artifact Under Review

• Instance reviewed: Python source code of milestone 003 (type PY): the Python files that this milestone added or changed, on branch mil-003-shapes-and-random-color at commit c695c47
• Checklist used: QC-PY-001 (QC-PY-001, Python Source Code)
• Milestone: MIL-003, tasks 1 to 6 (#16 to #21); this record is the review task, issue #22
• Scope: full review of the 8 Python files this milestone added or changed: src/turtle_challenges/__init__.py, src/turtle_challenges/cli.py, src/turtle_challenges/colors.py, src/turtle_challenges/constants.py, src/turtle_challenges/shapes.py, tests/test_colors.py, tests/test_constants.py, tests/test_shapes.py.
• Toolchain at that commit, run in a clean checkout of the branch: ruff format --check . and ruff check . exit 0, mypy reports no issues in 20 source files, pytest reports 66 passed, and doxygen Doxyfile prints no warning.
• Language and domain: n/a (technical type)
• Language reviewer: none (n/a)
• Reviewer eligibility: S01 is the author of this code (the assistant wrote it for S01) and also its reviewer, which framework/process/review-checklist-process.md does not allow. S01 accepted this deviation in chat on 2026-10-07; it is recorded in the traceability matrix.
• Status of this record: decided on 2026-10-08 by S01, the reviewer. The statuses and evidence are the assistant's assessment from the toolchain, an AST scan and a reading of the code, confirmed by S01.

Checklist Results

#	Criterion	Status	Evidence/Notes
1	Packages, modules, functions, variables, classes and constants follow PEP 8 casing (snake_case, PascalCase, UPPER_SNAKE)	Pass	Modules colors and shapes, functions random_color, random_palette_color, draw_shape and draw_shapes and the tests are snake_case; constants such as COLOR_PALETTE and MIN_POLYGON_SIDES are UPPER_SNAKE. No class is defined. ruff N is clean.
2	Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes	Pass	Names state purpose (num_sides, side_length, random_palette_color); no single-letter names (scan). Short names: rng (every docstring explains it as the random generator to draw from), red, green, blue, and tim, carried over from cli.py (see RC-015).
3	Code is produced by the project's formatter and passes its linter with no unexplained suppressions	Pass	ruff format --check . and ruff check . exit 0; no # noqa, no # type: ignore.
4	Every function and method signature is type-annotated, including -> None	Pass	Every parameter and return is annotated (scan: none unannotated); mypy strict is clean.
5	No bare except:, no swallowed exceptions; specific exceptions are raised and the cause is kept (raise ... from)	Pass	draw_shape raises ValueError for fewer than 3 sides or a side that is not positive; no code in this milestone catches an exception.
6	No mutable default arguments and no shadowed builtins	Pass	Scan of the changed files: no mutable default argument and no shadowed builtin (parameters, variables, functions, classes).
7	Files, locks and connections are managed with context managers	N-A	No file, lock or connection is opened (scan: no open().
8	Public modules, classes and functions have docstrings that say what, not how	Pass	Optional. Every public module and function in src/ has a docstring (scan: none missing); doxygen Doxyfile has 0 warnings.
9	Logging uses logging, not print; no secrets or personal data in log output	Pass	No print call (scan) and no logging; no secret is read.
10	Classes and operations trace to the Design Class Diagram they implement; deviations are recorded	N-A	No class is defined and no design class diagram exists; the tasks are plain technical tasks (see RC-015 criterion 10). S01 confirmed N-A on 2026-10-08.
11	Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network	Pass	66 tests (37 new), named for the behaviour: type, range and seeded repeatability of random_color; the turn angle and the side count for each shape from 3 to 10 sides (parametrised); the ValueError cases; the palette use of draw_shapes. They pass in file order, in reverse order and file by file; no network imports (scan).
12	Type checker runs in strict mode without errors; Any is justified in a comment	Pass	Optional. mypy strict reports no issues in 20 source files; Any is not used.
13	Dependencies are declared and pinned in the project's dependency file, none unused	N-A	Optional. No dependency changed in this milestone; see RC-014.

Overall Verdict

Go — all mandatory criteria of QC-PY-001 pass or are N-A. S01 confirmed N-A for criterion 10 on 2026-10-08, as in RC-015.

Reviewer eligibility: S01 is the author of this code and also its reviewer, which the review process does not allow; S01 accepted this deviation in chat on 2026-10-07 and it is recorded in the traceability matrix.

The row of the code in the traceability matrix is updated, and issue #22 closes through the commit message when the pull request that carries it merges into main.

Action Items

Action	Owner	Due
