Column binding sorts expression references before binding · case 04

Column binding sorts expression references before binding.

Case contract

Resolve query references [qualifier-or-None,name] against schema entries [relation,name,field-id]. Unqualified names bind only when exactly one matching column exists. Qualified names use both relation and name; no candidates yields MISSING and several yield AMBIGUOUS. Return stable field IDs.

Why this case matters

A bounded deterministic data engine model makes representation and changelog faults reproducible.
