Successful worker transport can carry an explicit failed parser status
with no semantic projection. Preserve that producer fact through the
shared source-availability interpretation used by full and incremental
graph construction, rather than dropping the source's semantic scope.
Retain the module when capacity permits, per-family incomplete-module
unknowns, and unknown omitted extents. Preserve existing operational
failure reasons and limits without classifying syntax as resource loss.
Document this coverage behavior.
Validation: regression-first run had 3 expected failures; all 22 selected
projection and public CLI source-selection/HTML cases passed after repair.
No JavaScript target execution or live external provider was involved.
