+### Scope-resolution property-key dispatch cap
+
+During scope resolution GitNexus synthesizes CALLS edges through *property-key
+dispatch* — call sites like `hooks.emitScopeCaptures()` where a property key is
+registered by multiple definitions across the codebase. To keep this fan-in
+bounded, each property key is capped at **32 registrations**: a key registered
+by more than 32 distinct functions is skipped entirely (no CALLS are synthesized
+through it), and the dropped key names are surfaced in the analyze log for
+operator visibility. The cap is calibrated at 2× this repo's own provider table
+(16 legitimate registrations, one per language provider).
