Review Comment:
   These variables read the unpartitioned placeholder files created by 
`ci-setup`, which remain empty because this job skips scope computation. The 
downloaded partition files use suffixed names, and the dependency graph is not 
included in the artifact either. As a result, every partition summary omits its 
build scope and presents a full-build reproduction command instead of the 
commands for the modules this job actually tested. Upload/download the graph 
and point the summary at `maven-pl-{affected,upstream}-${{ matrix.partition 
}}.txt` (and provide an appropriately partitioned changed set).

Review Comment:
   Label-based routing is incomplete. This workflow listens for `labeled` but 
not `unlabeled`, while `ci.yaml` listens for neither. Removing `parallel ci` 
therefore does not start the standard build, and adding it after a standard 
build has started does not trigger a standard-workflow run that can cancel that 
build, so the transition can leave either no replacement CI run or both builds 
running. Subscribe both workflows to `labeled` and `unlabeled`; their existing 
job conditions can then route each event and concurrency can cancel the 
superseded run.

Review Comment:
   This traversal includes every seed, so every assigned module is written to 
both the partition's upstream file and its affected file. The workflow 
consequently installs every affected module once with tests skipped and then 
installs it again with tests; the committed goldens confirm complete overlap 
(for example, all 452 default affected modules in scenario 03 also appear 
upstream). This substantially duplicates the expensive work this PR is intended 
to parallelize. Keep other-partition dependencies in the upstream set, but 
exclude this partition's own assigned modules; derive the image-producer 
prebuild list from the union before exclusion so affected image producers can 
still be built ahead of their consumers.
