`const_item`/`static_item` ride extractVariable's generic fallback, which
minted the node and stopped — the initializer was never walked, so every call
inside it was missing from the graph:
const LEN: usize = compute_len(); // no caller
static REGISTRY: Lazy<Cfg> = Lazy::new(|| build_cfg()); // no caller
That second shape is how once_cell/lazy_static singletons, handler tables and
static configs are written, so whatever they build looked unreferenced.
Fix: walk the `value` field through visitFunctionBody with the declared symbol
pushed on the scope stack. The fallback is shared, so the walk is gated to
Rust — the other languages on it spell their initializer differently and get
their own turn. The declared symbol is identified by the `name` FIELD, so the
phantom node the fallback also mints for a bare-identifier initializer
(`const MAX: u32 = OTHER;` → `MAX` plus a spurious `OTHER`) is left exactly as
it is: a separate defect, deliberately not folded in.
Measured on three Rust projects (gnss_rust, emmc-reader-gui,
bot_predlogka_rust — 282 files): 0 lost refs, 0 re-attributed, +86 new; node
and edge counts unchanged. Kernel parity holds (226/226 non-deferred files
byte-identical).
