The game updates the price and owned text at once but the affordable flag only at its next redraw, so a second purchase in the same visit used a stale flag. Buying at most one product per visit cut the failed purchases from about 40 percent to 1 of 49 and raised the CPS from 16.6 to 29 in the 300 second Docker run. README, screenshots and the wiki in en, da and ms show the new result. Task: MIL-006#1 Task: MIL-006#2 Task: MIL-006#3 Task: MIL-006#4 Task: MIL-006#5

# Step 4: buy upgrades

`get_store_items` reads the 20 store products, `choose_upgrade` picks the most expensive one the bot can afford, and `buy_upgrade` clicks it. The screenshot shows the first cursor bought.

**Function**
|
|
|
|
```python
|
|
def choose_upgrade(items: Sequence[StoreItem]) -> StoreItem | None:
|
|
affordable = [item for item in items if item.is_affordable]
|
|
if not affordable:
|
|
return None
|
|
return max(affordable, key=lambda item: (item.price, item.index))
|
|
```
|
|
|
|
## What we gained
|
|
|
|
- **Keep the decision pure.** `choose_upgrade` takes plain `StoreItem` values and returns one, so it is tested with no game at all (ties, none affordable, empty list).
|
|
- **Confirm the result, do not assume it.** `buy_upgrade` checks that the owned amount (`productOwned<N>`) went up. Checking the cookie count first was wrong: the count keeps rising while the bot clicks.
|
|
- **The page lags behind.** The first release lost about 40 percent of its purchases: the game updates the price and owned text at once but the affordable flag only at its next redraw, so a second purchase in the same visit used a stale flag. Buying at most one product per store visit cut the failures to 1 of 49.
|
|
- **The real game finds what fakes cannot.** The stale-element retry and the owned-amount check both came from running in Docker.
