Verification report
- Main manuscript compiled successfully after catalogue/forward-modelling insertion.
- Main PDF: 20 pages; no unresolved "??" cross-references detected by pdftotext.
- Supplement PDF retained from the polished package.
- Added catalogue schemas for halo catalogues, BH feeding histories and forward-modelled observables.
- Added deterministic smoke-test CSVs only for interface validation; they are explicitly not simulation evidence.
- Added three catalogue/forward-modelling figures: halo catalogue, BH feeding curves and forward observable space.
