Locale capability track, slice 2 (#882): a context whose direct uses reaches two or more message-bundle commons has no principled single answer for what Locale.current() should negotiate against — but this is only worth diagnosing when the context actually consumes bynk { Locale } at all; a context with 2+ bundles that never touches Locale has nothing ambiguous to resolve.

P5.0 (design/tracks/semantics-in-the-checker.md §6): relocated verbatim from bynk-emit/src/project/validate.rs’s check_locale_bundle_ambiguity — category 3 of analysis.rs’s own seven-category accounting, the second of this slice’s two live editor-diagnostics regressions.
