아하, 내 실수였어 🤦♂️ [기능](https://github.com/discourse/discourse/pull/39072)이 **제한** 관련해서 조금 더 "지능적"이어야 했어 🙂

> When searching tags in the composer, \`filter\_allowed\_tags\` applies a LIMIT (\`max…\_tag\_search\_results\`, default 5). If more allowed tags match the query than fit under the limit, the overflow is silently dropped.
>
> \`append\_disabled\_tags\` then ran a naive substring query for visible tags matching the term, assumed any tag not in the allowed list must be excluded by filter rules, and asked \`explain\_exclusion\` to fabricate a reason. Allowed-but-cut-off tags leaked into the disabled list and showed the vague fallback "\\"X\\" cannot be used in this category".
>
> Because \`filter\_allowed\_tags\` orders by term (\`DISTINCT ON (lower(name) = lower(term), ...)\`), the same tag could appear allowed under one search term (prefix match, ranks high, fits in the limit) and disabled under another (mid-string match, ranks lower, gets cut off) — producing inconsistent verdicts for the same tag in the same category.
>
> Before labeling any tag as disabled or forbidden, re-run \`filter\_allowed\_tags\` scoped to the candidate names (no limit) and drop any that come back allowed. Extracted to \`reject\_allowed\_tags\` so both \`append\_disabled\_tags\` and \`detect\_forbidden\_tag\` go through the same verification. The probe is skipped when the allowed result didn't saturate its limit, since no cutoff is possible in that case.
