The base seam branch still carries the buggy /^__.+__$/ (rejects `____`,
which its own reserved.spec asserts must match), so this stacked branch must
keep the /^__.*__$/ correction to stay green. Reword the JSDoc to the same
line count as the base so the CodeRuntime class does not shift, leaving the
cordis services catalog anchor identical to the base and confining this
branch's footprint on the seam file to the single regex character.
