Fan-out: chained composition (weekly → daily → hourly)

[Lee-W]

Body

What

Support multi-level fan-out where a downstream of one fan-out is itself the upstream of another. Example: a weekly release fans out to daily scoring runs, each of which fans out to hourly segment runs. The graph must compose cleanly without combinatorial blowup.
