resolveBareCallee's flat-collect branch counted ALL same-name authors — including #foreign / generic / builtin / #compiler — before the isPlainFreeFn filter, so two flat-imported modules each #foreign-ing the same libc symbol under one sx name returned `.ambiguous` and errored, instead of falling to `.none` and the existing first-wins foreign path (master behavior). Filter authors to plain free functions DURING collection, before the count/ambiguity determination: a non-plain collision now yields 0 reroutable authors -> `.none`; genuine plain-fn collisions still yield >= 2 -> `.ambiguous` (0724 unchanged). The now-redundant single-author isPlainFreeFn check is dropped. Regression: examples/0729-modules-flat-same-name-foreign — two flat FILE imports each #foreign the same libc "abs" under name `absval`; a bare call resolves first-wins and runs (exit 0). Fails-before on this branch (ambiguity error), passes-after.
