C++ calls now resolve through the include closure: header prototypes pair
with definitions in other translation units, lookup walks class (including
in-repository bases), namespace, and `using` scopes outward, and static or
anonymous-namespace definitions stay file-local. Member calls resolve only
through explicitly declared receiver types (parameters, locals, fields,
this, smart pointers, aliases); template parameters stay unknown. Calls
hidden by the most vexing parse are recovered, casts are no longer calls,
reference-returning and conversion-operator declarations are named
correctly, and benign `= {}` default-argument recoveries no longer drop
prototypes or flag files.
Rust method calls resolve through a crate-wide impl index for self, typed
parameters and lets, struct fields, Self-returning constructors, dyn
traits, and Type::/Self:: associated calls, with foreign imports and
generics never guessed. Calls inside expression macros are re-parsed.
Every unresolved call records source.unresolved-reason, weaker resolutions
record source.resolution/source.extraction, and metrics.resolution reports
per-language call-site coverage. Declarations gain facts consumed by
caller-status queries (qualified names, linkage, virtual, trait impls,
attributes, name references, parse-incomplete). C++/Rust External targets
include the reason in their identity; out-of-line C++ methods keep their
IDs.
Linear node/edge scans and per-node ancestor walks are replaced with
indexes, cutting a YAMS scan from 575 s to 23 s.
New labeled cpp_xtu and rust_methods corpora run three times in the
quality gate.
