track linited per local alongside the ownership state; snapshots, exit records and joins carry it, and a join keeps a local set only when every reaching path set it. x = e, a declaration initializer, &x (out-parameter), a full array initializer, or using an aggregate as an address set a local; field and element writes do not set the aggregate. while/for bodies that may run zero times do not count; do/while does. compiler, runtime, std, actor and lsp sources initialize the locals the rule flagged; zc0 accepts = {} brace lists (zeroed). tests: tests/errors/uninit_*.zc, tests/conformance/4-statements/uninit_*.zc

rt.MW is the end of the fixed map (PW) since the growing heap landed; the
heap starts right there, so ld16(addr_b(rt.MW)-1) read the heap's first
byte: 0 on the default map by luck, 0x40 on the small map (16384).
Probe the real byte-op bound instead: core answers syscall(9,10) with the
host reservation MW; micro ports, whose bound is their memory size, fall
back to syscall(9,0).
