The last bug-pinned C carrier. Its header documents both #55 halves; with the cgen side fixed the STRONGER assertion set it deferred is expressible: barevalue builds the 794 two-file program FLAT (file-keyed import — a dir-keyed aa/ compiles aa as its own sep unit where main.v is invisible and the collision cannot express), runs exit 7 on BOTH drivers, and asserts the flat __root.s cs==ww byte-identical (rule 10). defshadow pins the def-vs-fn arm-order corner (foreign scalar def under a curmod fn: bare read 42, not 141), modqualfnval the qualified fn-value positive twin. Carrier fleet 16 -> 15: 5 units / 6 bootstrap / 3 platform / 738_module_decl. Zero bug-pins remain.
