Draft: [DATA01] Map implementation and test gaps for N01-N32

DATA01 gap analysis for APP-2026-09-19. Maps N01-N32 to current modules and regression evidence, records missing independent checks and engineering review, and confirms M1 was already implemented in merged !35 (merged). Validation: docs 1686/1686; catalogue valid (97 planned cases, 236 mapped regressions); M1-focused local tests 35/35; GitLab main pipeline 10950 8/8 and MR !35 (merged) pipeline 9712 6/6. No solver behavior or acceptance status changed; all N01-N32 remain NOT_VERIFIED and M4 is open. Organizer answers from 29 Sep are present in the user's working copy but are not part of origin/main or this MR; the report flags the source drift.
