// E6b — own-wins-over-flat for ERROR-SET per-decl nominal identity. `main`
// flat-imports `dep.sx` (which authors `IoErr { Net }`) AND authors its OWN
// `IoErr { Disk }`. A bare `IoErr` reference in `main` resolves to `main`'s OWN
// author, not the flat-imported one (the querying source's author wins outright —
// no ambiguity), so `e : IoErr = error.Disk` binds `main`'s set (whose `Disk` tag
// dep's `IoErr` lacks) while `dep_err()` returns dep's DISTINCT `IoErr`.
//
// Fail-before (pre-E6b): the stateless `type_bridge.resolveInlineErrorSet`
// `findByName` short-circuit interned ONE global last-wins `IoErr`, so `main`'s
// `IoErr` and dep's `IoErr` collapsed to a single nominal. Whichever author won
// the global slot, the OTHER module's tag is not in it — so exactly one of
// `error.Disk` (main) / `error.Net` (dep, in `dep_err`'s body) fails its
// membership check and the program exits 1.
//
// Pass-after: distinct nominal TypeIds — `error.Disk` validates against main's
// `{ Disk }` and `error.Net` against dep's `{ Net }`, both pass, exit 0.
