X_BACKFILL_SLICE_ENTITY

the slice holds no entity a generated backfill can sweep

x g backfill --feature <slice> writes a sweep over the slice's own scaffolded table (db.<plural>, its title column); the slice exists and its entity.ts declares other tables, so the generated files would not compile

x g job <name> --feature <slice> — then wrap its body in backfill({ source: db.<your table>, … }) from @ultimat3/jobs
