## Artifact Under Review
- Instance reviewed: [MIL-008]
- Checklist used: [QC-PY-001] (`QC-PY-001`)
- Scope: full review of the source and tests added by MIL-008: the best value rule `choose_best_value`, the `BEST_VALUE` strategy, the production read in the Selenium adapter, the `--best-value` option and 19 new tests; four 300 s container runs produced the comparison
- Language and domain: n/a
- Language reviewer: none
- Mode: autonomous, not independent (the reviewer is `AI as stand-in for S02`)
## Checklist Results
| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) | Pass | ruff (N rules) passes; names follow PEP 8 casing. |
| 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes | Pass | Names use the terms of DICT-001 (cookie, upgrade, bot); no single-letter names outside comprehensions. |
| 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions | Pass | `ruff format` and `ruff check` pass with the rules in `pyproject.toml`; no suppressions. |
| 4 | Every function and method signature is type-annotated, including `-> None` | Pass | `mypy --strict` passes; every signature is annotated. |
| 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) | Pass | No bare `except`; ruff B and S rules pass. |
| 6 | No mutable default arguments and no shadowed builtins | Pass | No mutable defaults; ruff B006 and A rules pass. |
| 7 | Files, locks and connections are managed with context managers | Pass | The browser is closed in a `finally` block in `main`. |
| 8 | Public modules, classes and functions have docstrings that say what, not how | Pass | Public modules, classes and functions have Doxygen docstrings with `@brief`. |
| 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output | Pass | Diagnostics use `logging`; the required result line `cookies/second: N` is the program's output, not a log; no secrets are read or logged. |
| 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded | N-A | No Design Class Diagram exists (ADR-0001 skips use case design); ADR-0002 records the layout instead. |
| 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | 135 tests pass with fakes; 100% coverage of the logic modules; tests cover the new rule, the production read and its failure paths. |
| 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` lists Selenium as the only runtime dependency; dev extras are test and lint tools. |
| 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 | Constants live only in `constants.py`; rules are defined once. |
| 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 Selenium; `application` depends on a port; no import 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 | Modules have one reason to change; the game is behind a narrow port. |
| 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` under `src/`, `unit` and `integration` under `tests/`; no `presentation` package by ADR-0002. |
| 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 names, snake_case files, no spaces. |
## Overall Verdict
Go — the code of MIL-008 meets every Mandatory criterion; `ruff`, `mypy --strict` and `pytest` were run and pass. The review is not independent: the AI wrote and reviewed it as stand-in for S02, and S01 can challenge it in the end-of-run summary.

Det ville få betydning senere, når antallet af cookies rummer flere produkter på én gang.
## En smartere regel: bedste værdi
`--best-value` ser ikke kun på prisen. Spillet fortæller, hvor mange cookies pr. sekund én enhed af hvert produkt giver, og botten køber det produkt, der er råd til, med den laveste pris pr. cookie pr. sekund (`choose_best_value`). Cursor koster 15 og giver 0,1 (150 cookies for hver cookie pr. sekund), Grandma koster 100 og giver 1 (100 for hver), så Grandma er det bedste køb, selv om den koster mere.
```bash
cookie-clicker-bot --best-value
```
Hver række er en fuld kørsel på 300 sekunder alene i en Docker-container, den ene efter den anden, tjek hvert 5. sekund:
| Kørsel | Strategi | cookies/sekund | Købt |
| --- | --- | --- | --- |
| 1 | dyreste, der er råd til | 18 | 30 Cursor, 15 Grandma |
| 2 | bedste værdi | 17.9 | 29 Cursor, 15 Grandma |
| 3 | dyreste, der er råd til | 18.8 | 28 Cursor, 16 Grandma |
| 4 | bedste værdi | 18.8 | 28 Cursor, 16 Grandma |
Den smartere regel er **ikke bedre**: de to regler adskiller sig mindre end to kørsler af den samme regel (18 og 18,8). Årsagen er den samme som for køb alle. På 5 sekunder klikker botten omkring 125 cookies, så der er kun råd til Cursor og Grandma, og begge regler køber næsten det samme. En regel, der ser på værdi, ville få betydning, når der er råd til flere produkter på én gang, for eksempel med et længere tjekinterval.

## Peraturan yang lebih bijak: nilai terbaik
`--best-value` tidak melihat harga sahaja. Permainan memberitahu berapa kuki sesaat yang dihasilkan oleh satu unit setiap produk, dan bot membeli produk yang mampu dibeli dengan harga terendah bagi setiap kuki sesaat (`choose_best_value`). Cursor berharga 15 dan menghasilkan 0.1 (150 kuki bagi setiap kuki sesaat), Grandma berharga 100 dan menghasilkan 1 (100 bagi setiap satu), jadi Grandma ialah belian yang lebih baik walaupun lebih mahal.

Peraturan yang lebih bijak ini **tidak lebih baik**: perbezaan antara kedua-dua peraturan lebih kecil daripada perbezaan antara dua larian peraturan yang sama (18 dan 18.8). Sebabnya sama seperti beli semua. Dalam 5 saat bot mengklik kira-kira 125 kuki, jadi hanya Cursor dan Grandma yang mampu dibeli, dan kedua-dua peraturan membeli hampir perkara yang sama. Peraturan yang melihat nilai akan penting apabila beberapa produk mampu dibeli sekali gus, misalnya dengan selang semakan yang lebih panjang.

- Checking more often is not better. Every check reads the page and takes time away from clicking, and the most expensive affordable product is usually only a little better than the cheaper one you could have bought a moment before. - Checking more often is not better.

- Buy all makes no difference early in the game: only Cursor and Grandma are affordable, and the bot buys them anyway. It would matter later, when the cookie count holds several products at once. - Buy all makes no difference early in the game: only Cursor and Grandma are affordable, and the bot buys them anyway. It would matter later, when the cookie count holds several products at once.
## A smarter rule: best value
`--best-value` does not look at the price alone. The game tells how many cookies per second one unit of each product makes, and the bot buys the affordable product with the lowest price per cookie per second (`choose_best_value`). Cursor costs 15 and makes 0.1 (150 cookies for each cookie per second), Grandma costs 100 and makes 1 (100 for each), so Grandma is the better deal even though it costs more.
```bash
cookie-clicker-bot --best-value
```
Each row is a full 300 second run alone in a Docker container, one after the other, check every 5 seconds:
| Run | Strategy | cookies/second | Bought |
| --- | --- | --- | --- |
| 1 | most expensive affordable | 18 | 30 Cursor, 15 Grandma |
| 2 | best value | 17.9 | 29 Cursor, 15 Grandma |
| 3 | most expensive affordable | 18.8 | 28 Cursor, 16 Grandma |
| 4 | best value | 18.8 | 28 Cursor, 16 Grandma |
The smarter rule is **not better**: the two rules differ by less than the difference between two runs of the same rule (18 and 18.8). The reason is the same as for buy all. In 5 seconds the bot clicks about 125 cookies, so only Cursor and Grandma are ever affordable, and both rules buy nearly the same. A rule that looks at value would matter once several products are affordable at once, for example with a longer check interval or after the first minutes of luck.
