Artifact Under Review

• Instance reviewed: MIL-004
• Checklist used: QC-PY-001
• Scope: full review of the source and tests delivered by MIL-004 (src/, tests/)
• Language and domain: n/a
• Language reviewer: none (the reviewer reads English and knows the IT domain)
• Mode: autonomous, not independent (AI as stand-in for 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, functions and constants use snake_case / UPPER_SNAKE; classes none or PascalCase.
2	Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes	Pass	Names follow the lecture and the domain dictionary.
3	Code is produced by the project's formatter and passes its linter with no unexplained suppressions	Pass	ruff format leaves files unchanged and ruff check (E, F, I, B, UP) passes; configured in pyproject.toml.
4	Every function and method signature is type-annotated, including -> None	Pass	Every function signature is annotated, including -> None.
5	No bare except:, no swallowed exceptions; specific exceptions are raised and the cause is kept (raise ... from)	Pass	No bare except and no swallowed exception.
6	No mutable default arguments and no shadowed builtins	Pass	No mutable defaults; no builtin shadowed.
7	Files, locks and connections are managed with context managers	N-A	No file, lock or connection is opened.
8	Public modules, classes and functions have docstrings that say what, not how	Pass	Module and public names carry docstrings plus Doxygen comments.
9	Logging uses logging, not print; no secrets or personal data in log output	N-A	Console output of the demo entry points (print under the main guard) is the program's result, not diagnostic logging; no secrets handled.
10	Classes and operations trace to the Design Class Diagram they implement; deviations are recorded	N-A	No DCD exists in this project; the layered layout is recorded in ADR-0001.
11	Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network	Pass	pytest tests named for behaviour; no order or network dependence.
12	Type checker runs in strict mode without errors; Any is justified in a comment	N-A	No type checker is configured (optional criterion).
13	Dependencies are declared and pinned in the project's dependency file, none unused	Pass	Dependencies are declared in pyproject.toml; none unused (Flask is the optional web extra).
14	Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike	Pass	Each constant is defined once in the constants.py of its layer.
15	Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles	Pass	domain imports no framework or outer layer; imports point inward; no cycles.
16	SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations	Pass	Small modules with one reason to change; no type tests or subclass hierarchies.
17	Source is laid out in the layers and folders of the clean architecture folder structure (domain, application, infrastructure, presentation packages under src/, and unit, integration and e2e under tests/), in snake_case, and imports between the layers point inward	Pass	Layers domain, application, infrastructure, presentation under src/flask_day_54; tests in unit and e2e (ADR-0001); no layer merged.
18	File and folder names are English, contain no space and no character outside letters, digits, -, _ and ., and follow the casing of the language for files	Pass	English snake_case file names without spaces.
