nx_pabi.nx -- THE PORTABLE SYSCALL ABI SEAM (operator 2026-07-16: "don't defer, eat our debt, build the tools we need; target the OS on rv64 AND x86 AND all hardware mobile+non-mobile so the forge works on them too, as resources permit locally/forest/cloud"). This is R1 (the FOUNDATIONAL rock from nx_forge_os_readiness) STARTED, not deferred. THE DEBT: every forge organ imports nx_syscalls hard-wired to Linux-x86-64 (raw `syscall` insn). That binds the forge to ONE OS. THE FIX: an ABI INDIRECTION -- the forge's file/mem/etc. surface as a stable interface with PLUGGABLE BACKENDS selected at call time: PABI_LINUX -> the host kernel via sys_* (today's path; any Linux/arch) PABI_NISHIOS -> NishiOS-native via the sovereign block-VFS (nx_vfsblock_lib) -- no Linux kernel It is ARCH-AGNOSTIC by construction (NishiLang source -> whatever nx_cc backend: x86-64 today, RV64/ARM as the compiler gains backends), so the SAME forge code runs on x86 laptops, RV64, and mobile/non-mobile targets. The swarm admission plane (nx_swarm_admit/queue) then PLACES the forge where resources permit (local / forest / cloud). This module ships the FILE subset (the deterministic core's need: the byte-exact judge reads/writes candidates+store+ledger); mem/proc/ clock backends are the next increments on the same seam. license_tier: ORIGINAL
