Koshin Studio“That’s just a Beyblade” came back after I added a gate: the blocked value leaked in another form
Development log of the Toreca Dash app / September 2026
My app Toreca Dash received three reports: “this is just a Beyblade”. An app that gathers trading-card information had a toy, Beyblade, registered as a product.
On 6 September I had added a gate: “do not create a product if the product name contains a toy’s name”. Yet it came back. This article is about a value I had blocked coming back in a different form.
Numbers come from my work logs of 6 to 11 September 2026.
I added the gate, but the toy’s name had vanished from the product name
The store announcement was:
New toy: Beyblade X
(1) CX-19 Random Booster Kuro Tread set
(2) CX-00 Tigerage FT3-60TAn AI builds product names from it, and the products created were:
"CX-19 Random Booster Kuro Tread Select"
"CX-00 'Tigerage' FT3-60T"Neither contains the word “Beyblade”. My gate rejected a product name that contained a toy’s name. Because the AI’s product name no longer had it, the gate let it through. The value I had blocked (the toy’s name) returned in another form (a product name without it).
The fix: judge on the announcement text, not the product name
I moved the judgement to the announcement body, not the product name. The body states the toy’s name.
But “contains a toy’s name, so reject” would not do. Store announcements sometimes list both toys and card games, such as “[Beyblade] [Dragon Ball Card Game]”. Rejecting would remove real lotteries. So the rule is: reject only when no card-game word appears at all.
Counting on real data:
| What I checked | Count |
|---|---|
| Articles that touch a toy line | 44 |
| Of those, matching the rule (no card-game word) | 31 |
| Of those, displayed | only the reported one |
| Articles with a card-game word (all kept) | 13 |
What I learned
A blocked value comes back in another form. Follow where the value goes.
- When you add a gate, follow where the blocked value leaks. Stop it creating products and it survives in a title or another field.
- Judge close to the source of the material. The original announcement is more reliable than a product name processed by an AI.
- Do not reject on “present” alone. Listings are mixed, so limit it to “no other word at all”.
- Count what remains for a rejecting rule. I confirmed the 13 stay.
