Phase C of the unified resolver (R5 §C, §#3). Re-base the plain bare-name
call author onto the Phase B collector behind one shared SelectedFunc, so
every call-path consumer reads ONE author and they can no longer disagree
(fix-0102 F2). Behavior-preserving: 0722-0735 byte-identical, run_examples
stays at 475.
- SelectedFunc {decl, source, materialized?} replaces ResolvedAuthor in
BareCallee.func; CallPlan.Target gains a `selected` arm (calls.zig).
- selectPlainCallableAuthor: resolveBareCallee's body verbatim over
resolver.collectVisibleAuthors (.user_bare_flat) — the ONE graph-walk.
fnDeclOfRaw mirrors imports.fnDeclOf so the collector's all-domain authors
reproduce module_fns' fn-only view; every byte of the negative space is
preserved (own==winner → .none; non-plain-free → .none; filter-before-count;
≥2 distinct → .ambiguous). No eager materialization.
- selectedFuncId materializes the FuncId on demand (shadow-only), caching into
materialized — null until a site needs it (0102d: a shadow taken as a value
never lowers the winner).
- Six consumers route through the one selector: lowerCall variadic packing,
free-fn UFCS, fn-value, closure(fn), resolveCallParamTypes, and
expandCallDefaults (decl-only, no materialization). plan() produces the
SelectedFunc as `.selected`. Generic/comptime/foreign/builtin stay legacy.
- lower.test.zig: wire module_decls; selectPlainCallableAuthor verdicts
(own-winner → .none; ≥2 flat → .ambiguous; own-shadow → decl+source, fid
round-trips, materialized null).
Gate: zig build + zig build test (412 ok) + run_examples (475, byte-identical)
+ m3te ios-sim build exit 0.
