The gate file has never parsed: the two job names were plain scalars
containing ': ' (YAML 1.2 plain-scalar rule - a colon followed by a space
ends the scalar and starts a mapping, so the file fails to load). Gitea
cannot build a run from a file it cannot parse, and the tell is a
dispatch POST answered HTTP 500 with an empty body.
Measured at this seat, own PAT, own repo: dispatch on main -> HTTP 500,
dispatch on this branch -> HTTP 500, 0 run records, 0 queued jobs.
Quoting the two names is the whole change; gates, labels, toolchain and
the trigger shape (workflow_dispatch: {} -> workflow_dispatch:) are
unchanged. Evidence and the follow-up dispatch live on researchx#24.
