The local check is not a valid clause audit because it mixes in internal section numbers, ISO clauses and the standard's own name. Method-A is the most reliable. Method-B has a strong bibliography but cites standards by topic and does not apply its provenance tags. Method-C needs correction before adoption, especially its nonexistent SKOS properties, wrong Cimino numbers, squared MASI distance, wrong Z39.19 topics, conflated MLPerf citation, and unconfirmed single-child and IEEE P3116 claims."

Editorial scope note: static arena memory planning is an applicable on-device deployment technique for predictable allocation and fragmentation avoidance—chiefly required on bare-metal microcontrollers operating under kilobyte SRAM ceilings rather than a universal requirement across all edge SoCs and mobile NPUs; because mlsys.memory-planning is homed in subject S2.4 (ml-compilers) in area S2, it is linked here as a secondary concept rather than re-homed."
