Set the decision and its input
The supplied English and zh-HK profiles define labels, colon spacing and unit punctuation separately. A Chinese document with quantity zero must render 合共：0 件。 and lang=zh-HK. Merely setting the language attribute while retaining English output does not apply that profile.
| Case | Input JSON |
|---|---|
| Base test | {"locale":"zh-HK","quantity":0} |
Run the supplied comparison
The programme queries actual rendered text, the article language and the unchanged data value. The profiles are original supplied copy; no automatic translation equivalence is claimed.
| Path | Output JSON |
|---|---|
| Faulty path | {"lang":"zh-HK","text":"Total: 0 units.","quantity":"0"} |
| Required path | {"lang":"zh-HK","text":"合共：0 件。","quantity":"0"} |

Choose from the boundary evidence
English quantity three renders Total: 3 units. No French profile is supplied, so French output is held instead of falling back silently.
- Choose the supplied locale profile
- Render labels and value
- Inspect actual text and language
Hold a locale without its required profile.
| Condition | Input JSON | Expected output JSON |
|---|---|---|
| English profile | {"locale":"en","quantity":3} | {"lang":"en","text":"Total: 3 units.","quantity":"3"} |
| no supplied French profile | {"locale":"fr","quantity":3} | {"held":true,"reason":"profile-missing"} |
Does lang=zh-HK alone make the base document complete?
Show the worked answer
No. The actual label and punctuation must also use the Chinese profile. Quantity stays zero in both versions.
