Expand description

Repo-level structural metrics derived from one SCC + reachability pass. The single source of truth shared by architecture-metrics (HEAD) and architecture-trend (sampled history) so the two can never disagree on propagation cost or cycle structure.

Fields§

§n: usize

Node count — every live Tier-1 source file (plus any resolved-edge endpoint), so isolated files are included.

§ccd: f64

Cumulative Component Dependency = Σ visibility-fan-out (each file’s transitive dependency set incl. self). Feeds Lakos ACD/NCCD.

§propagation_cost: f64

Density of the visibility matrix = ccd / n² — “a change to a random file reaches this fraction of the system”.

§cycle_count: u32

Non-trivial dependency cycles (SCCs of size ≥ 2).

§largest_cycle: u32

Size of the largest cycle (0 if acyclic).

§cyclic_nodes: u32

Total nodes that sit in some cycle (for core-periphery dominance).
