about

_ar2_perf_probe.nx -- TIMING ORACLE for argon2id KDF params (vault machine-key v2 upgrade). Measures wall ms at candidate (m_kib, t) pairs so the chosen params are MEASURED, not guessed (no magic numbers). Run after the 2026-06-10 compiler bless; before this the module miscompiled. license_tier: ORIGINAL
