Four seams from one review cluster, all landing on the same checker files; gates ran on the union (rule 11 body). ?-subset: the wwstage walk compared `...spread` ALIAS nodes on both sides of the error-subset check, falsely rejecting a spread-carried error return (`(i64 | ...errs)`, cs-accept/ww-reject) — both sides now flatten like trycountvariants (cstage Tparams are pre-flattened at type level). Multi-let/multi-assign: the tuple gates keyed on the RAW rhs kind, rejecting a NAMED tuple alias (`type pair = (i64,i64)`; cs clean- reject, ww asserttyped stop) — both stages chase per #99 alias transparency, wwstage rettupleof peels the alias so cgmassign keeps the str element's len/cap stores, and the catA massign-alias error pin re-rules to a run fixture. The N_MLET diagnostic also printed its operands swapped (elem/declared reversed vs its wording). Yield: match_yield_type didn't descend into N_SWITCH, so a yield inside a switch arm typed the match void and dropped the value (both stages); and a stray yield outside any match arm reached cgen unchecked — both stages now gate on a match-arm counter (the c->loops discipline).
