Artifact Under Review

• Instance reviewed: MIL-003
• Checklist used: QC-PY-001
• Scope: Code of MIL-003: domain, application, infrastructure and presentation/web packages, server.py, and the unit and integration tests; written by the python-developer agent
• Language and domain: n/a (technical type)
• Language reviewer: none
• Mode: autonomous, not independent (the reviewer is 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 and functions use snake_case, classes PascalCase, constants UPPER_SNAKE
2	Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes	Pass	Names state purpose (compare_guess, GuessResult, HOME_HEADING); no unexplained abbreviations
3	Code is produced by the project's formatter and passes its linter with no unexplained suppressions	Pass	ruff check and ruff format --check report no finding; no suppressions
4	Every function and method signature is type-annotated, including -> None	Pass	Every signature is annotated; mypy --strict reports no issue
5	No bare except:, no swallowed exceptions; specific exceptions are raised and the cause is kept (raise ... from)	Pass	No bare except; no exception is swallowed
6	No mutable default arguments and no shadowed builtins	Pass	No mutable default arguments; no builtin is 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	Public modules, classes and functions have Doxygen-style docstrings
9	Logging uses logging, not print; no secrets or personal data in log output	Pass	No print; no secret in the code; .env is neither read nor imported
10	Classes and operations trace to the Design Class Diagram they implement; deviations are recorded	N-A	No DCD exists (plain technical tasks)
11	Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network	Pass	pytest tests are named for behaviour, run in any order and use no network
12	Type checker runs in strict mode without errors; Any is justified in a comment	Pass	mypy --strict passes; no Any
13	Dependencies are declared and pinned in the project's dependency file, none unused	Pass	pyproject.toml declares Flask (runtime) and pytest, ruff, mypy (extras); none unused
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	The comparison rule is only in domain/rules.py; headings, colours and GIFs only in constants.py
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 only the standard library; application imports domain and constants; infrastructure imports only the standard library; presentation imports application, infrastructure and Flask; no cycle
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	Each module has one reason to change; behaviour is added by extension
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	Domain rule, application use case, infrastructure random source and presentation web app sit in their layer packages; tests in tests/unit and tests/integration
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	File and folder names are English with letters, digits and _ only
