about

nx_js_arena_gate.nx -- escape-aware ARENA RECLAMATION. Proves (A) call-heavy code that USED to exhaust the 32MB env arena (~fib27) now COMPLETES (fib(32)=4.3M calls, fib(34)=5.7M -- was rc=1); (B) the escape guard is CORRECT: closures that OUTLIVE their creating call keep their captured env (NOT wrongly reclaimed), verified vs the tree-walker oracle. Conservative-correct stack-discipline reclaim, not a tracing GC. (Inline/cell-reuse style: each compile_run mmaps a fresh 32MB arena not munmap'd, so we keep runs few.) expect_exit: 0 license_tier: ORIGINAL
