nx_hw_envelope.nx -- HARDWARE-AWARE MODEL ROUTER (2026-07-23; operator: "hardware aware component if we shift to larger or smaller systems so future nishi os can run on anything from a phone to a supercomputer"). Measures the HOST envelope (RAM via /proc/meminfo, logical cores via /proc/cpuinfo, both STREAM-read because /proc stat sizes lie) and picks the maker/bench model roster for this hardware TIER from the sovereign plane knowledge/store/hwtier- (rule 11: thresholds AND rosters are DATA -- rows `tier|min_gb|maker|bench|note`, pipe-packed payload = the declared-canonical store row format). External models appear ONLY in the bench column and are marked BENCH-ONLY (the external-reimpls-bench-only law); the sovereign maker column is always the primary. Fail-closed: absent/empty plane = RED exit 1; no tier fits the measured RAM = RED exit 3; VRAM reports UNMEASURED in v1 (no honest sovereign probe yet), never guessed. nx_hw_envelope probe -- measure host -> JSON nx_hw_envelope route [planeprefix] -- probe + tier-match -> routing JSON (+ hw_envelope.out) nx_hw_envelope selftest -- hermetic teeth (gv lib) license_tier: ORIGINAL expect_exit: 0 No hw writes (Rule 26).
