Kind

dynamic-prefix family

What it means

two values cannot both hold.

What to do

one of them is wrong: aontu why names both and where they were written

This is a family, not a literal code

The engine never emits func: verbatim. It appends a name or a value — so you will see codes like func:upper — and class lookup falls back to the longest registered prefix. If you are matching codes, match by prefix for these five; exact equality will never fire.

Where this comes from

test/spec/errcodes.tsv, the shared registry both implementations execute and assert set equality against. The message text is deliberately not reproduced here: the engines are its catalogue, and a copy on this site would be a second source of truth for something already generated once. To read it, run the engine — or see the skill's error-code guide.
