Backport only the three type-system guards and focused regressions from 8fafaf9; omit the larger diagnostic-reporting refactor.
Backport only the independent bare labeled-arrow fix from 110534a; omit the broader external phantom-argument parser/printer rewrite.

Lam_beta_reduce built the bindings for non-substitutable arguments by prepending during fold_left2 (reverse parameter order) and then wrapped the body with fold_right, making the first parameter's binding innermost - so the last argument was evaluated first. Fold left instead, so the first parameter's binding is outermost and arguments evaluate in call order. The reversed order was visible in checked-in output: bs_set_int_test.mjs evaluated setEqArray's second argument before its first. The new inline_arg_order_test fixture pins the order with recursive (hence non-substitutable) effectful arguments; its checked-in JS would show the regression directly.

Summary
Prepare the conservative ReScript 12.3.1 maintenance release from
maintenance/12.x.The fixes were backported chronologically and adapted where necessary to avoid pulling newer infrastructure or broad refactors:

This intentionally excludes larger or more invasive master changes, notably:
The goal is to fix concrete correctness and crash issues without increasing maintenance-release regression risk.
Validation
