The result of an impact walk.

Fields

visited: SeqMap<VisitedEntry>

Visited files in discovery order across hops (the first hop a file is hit wins its slot). build_impact_model reads these keys in order to build the PPR nodes array, so this order is directly float-accumulation-order-visible downstream (see module header).

fwd_adj: HashMap<String, HashSet<String>>

The file-level subgraph in the blast-radius direction. A plain HashMap<_, HashSet<_>> because – unlike visited/frontier – an out-edge set’s iteration order does NOT affect personalized_page_rank’s float accumulation (each target in one node’s out-set gets exactly one independent +=), so no ordering wrapper is needed here.

seed_files: SeqSet<String>

The seed files, in seed_ids order flat-mapped through def_files.

braked: Vec<BrakedIface>

The interfaces the walk refused to widen through.

braked_files: Vec<BrakedFile>

The hub files the walk refused to widen through.
