"""demand_driven_data_exfil.
`Cap::DATA_EXFIL` parity for the backwards-analysis pass. The forward
engine emits a `taint-data-exfiltration` finding for the cookie →
fetch-body flow (Sensitive source, fixed destination URL). With
`backwards_analysis = true`, the post-pass must walk backwards from the
DATA_EXFIL sink demand, reach the cookie source, and annotate the
finding with `backwards-confirmed`. Validates that the cap-routing
logic in `taint/backwards.rs::DemandState` round-trips bit 13
(DATA_EXFIL) identically to the SQL/CMD/SSRF caps the rest of the
demand-driven suite covers.
