Final 0102 sub-step. fix-0102c landed resolveBareCallee and routed the primary call path + parameter target typing through it, leaving four other bare-name consumer sites on the old first-wins path. Route the SAME resolver through all four, gated exactly as the call path (plain top-level identifier, no scope-mangle / UFCS alias / local shadow; act on .func / .ambiguous, fall through on .none so single-author / local / std / qualified / foreign-single resolution is byte-for-byte unchanged): 1. Default-argument expansion (expandCallDefaults): omitted trailing args fill from the RESOLVED author's defaults, not the winner's. 2. Function-value conversion (closure(fn) and the bare-fn-as-value func_ref / fn-ptr / closure-coercion path): captures the resolved author's FuncId. 3. Free-function UFCS (recv.fn() -> fn(recv, ...)): dispatches the resolved author for the receiver's source. 4. Comptime #run of a bare call: lowerMainAndComptime now sets current_source_file per decl, so a `NAME :: #run f()` in an imported module resolves f from THAT module's flat imports (own-author wins) instead of the main file's perspective (which made it spuriously ambiguous). Regression tests: examples/0730-0734 (default-arg, closure+fn-value, UFCS, comptime #run, UFCS-ambiguity), each fails on pre-fix code and passes after. issues/0102-flat-import-same-signature-collision.md written RESOLVED with the 4-sub-step root cause and regression-test paths.

// fix-0102d site 1 (issue 0102): two flat FILE imports each author a same-name
|
|
// free function `cfg` with a DIFFERENT default value for its trailing param —
|
|
// a.sx defaults to 10, b.sx to 20. Each module calls `cfg()` bare with the arg
|
|
// OMITTED. The omitted trailing arg must be filled from the RESOLVED author's
|
|
// default (own-author wins), not the first-wins winner's. Before the fix,
|
|
// `from_b`'s `cfg()` expanded to the winner a.sx's default (10) and returned 10.
|
|
// Regression: per-source default-argument expansion.
