CMake Buildkite artifact discovery now uses buildkite-agent (
3832c85)
CI link steps were breaking because Buildkite no longer exposes the full jobs array in public build JSON, making the old scraper think builds had no jobs. This change replaces that approach with buildkite-agent artifact search, which is the right source of truth for sibling step artifacts and keeps the build link flow working.
Other misc changes
- None.
