A PR more than 100 commits ahead of its merge-base paginates the compare endpoint; pages after the first carry files: null, so the bare .files[] made jq die with 'cannot iterate over: null' on every retry and forced the classifier's fail-open path (all lanes on, ci_review gate demanding a label with zero CI-sensitive files in the diff). .files[]? keeps the page-one file list and ignores the null tail.

Classify a PR's changed files into CI work lanes (python, frontend, site,
|
|
scan, deps, mcp_catalog) so the orchestrator can conditionally call only
|
|
the sub-workflows a PR can affect. Outputs are always "true" on push/dispatch
|
|
events and fail open (everything "true") when the diff cannot be computed.
