Module join_predicates 

Join conjunct analysis and structural side binding.

Functions

bind_join_sides

Rebase selected right-input positions for independent key evaluation, borrowing expressions whose coordinates already match their own input.

decide_join_sides

Determine the input side of equality operands from structured identities and joined logical positions. Planning does not synthesize a sample row, and punctuation in a quoted identifier is never interpreted as a relation boundary.
