fold-2 chunk C4 (drew's Fam8-13 plan): 13 float value-row C drivers re-homed. 11 migrate to test/lang/*_test.ww @test row-tables (exact IEEE-bit asserts); 1 float-overflow reject row -> a runww //ww:error carrier. 956_tuprecv_f64 slims to a w6c_ww asserttyped pin (20 value rows -> @test; the stamp dimension can't be a value/byte-id @test) -- mutation-proven non-vacuous (break #121 stamp -> RED 6/6 -> restore -> GREEN) + an in-test vacuity self-check. 946_structparam/structret stay whole: their SSE register-class .s-grep (SysV ABI conformance, #165/#171a) is the genuine defect-guard, not @test-expressible. Float was the predicted SSE-cursor byte-id hotspot -- zero fresh cs!=ww surfaced; 951_f64cgen (cstage-only before) byte-ids clean. LANGBYTEID floor 82->93; test count 384->374 (10 deleted drivers; 956 + the 2 946 kept).

// f32stamp_test — un-suffixed f32-context literal checker-stamp, migrated from
|
|
// test/wcc/965_f32stamp_run.c (#5-C4, #104 fold-2). An UN-suffixed float literal
|
|
// in an f32 context (`let x: f32 = 1.0`, `return 1.0` from an f32 fn) must be
|
|
// stamped f32 by the checker so fold-1's cgen narrow fires; without the stamp it
|
|
// stays ty_untyped_float, materialises as a 64-bit double, and the f32 consumer
|
|
// reads the low 4 bytes (0.0f for clean values). SCOPE (#104 fold-2): the stamp
|
|
// fires at let-init and return ONLY — binop/unary/assign/call-arg/struct-field
|
|
// are deferred to #120, so this pins bare let-init / return literals exclusively.
|
|
// Both stages byte-identical; T1 cstage run is the live net, T2 byte-id rides.
