All inputs the extractor needs, gathered from the assembled brief data.

Fields

deltas: &'a ReviewDeltas

Diff-aware deltas (boundary + public-API). The candidate source.

boundary_anchors: &'a [BoundaryAnchor]

Boundary anchors keyed by zone-pair, one representative per introduced edge.

coordination: &'a [CoordinationAnchor]

Coordination gaps projected to the contract decision shape.

public_api_anchor_line: u32

1-based line of the first widened public-API export’s declaration, so the public-API-surface decision anchors to a real line. 0 when unresolved.

affected_not_shown: u64

Project-wide fan-in beyond the diff (impact-closure affected_not_shown). Used as the blast magnitude for boundary + public-API-surface decisions.

routing: &'a RoutingFacts

Ownership routing (routed expert per file).

head_source: &'a dyn Fn(&str) -> Option<String>

Per-anchor-file head source, for suppression checks. None for a file whose head content could not be read (the decision is then not suppressed).

rename_old_path: &'a dyn Fn(&str) -> Option<String>

Resolve a head (post-rename) root-relative path to its pre-rename path, from the diff’s rename pairs. None when the file was not renamed. Lets each decision carry a previous_signal_id so review memory survives a git mv.

internal_consumers: &'a dyn Fn(&str) -> u64

Honest per-anchor in-repo out-of-diff consumer count, precomputed from the retained graph’s reverse-deps before it was dropped. 0 for an anchor with no recorded importers (a genuinely new file). The display number; distinct from affected_not_shown (the project-wide ranking proxy).

cap: usize

The decision cap (default 4, clamped to [3, 5] by the caller).
