nx_coach_curriculum.nx

nx_coach_curriculum.nx -- the CURRICULUM-COACH ORGAN: a thin main() over nx_coach_curriculum_lib. The engine used to live in THIS file alongside main(), which meant nothing could import it -- so a second discipline could only reuse the curriculum coach by COPYING it, which is the duplication the estate is already RED on (179 cross-tree dup basenames). The core moved VERBATIM to nx_coach_curriculum_lib.nx (the estate's existing nx_gate_verdict / nx_gate_verdict_lib split) and this file kept only its self-gate. The proof of an extraction is that the organ's own verdict still reads exactly as it did before: 3/3 GREEN. The engine: assess -> serve the FRAMEWORK from the store -> roleplay -> grade the SELF-REPORT -> name the MISSING element -> drill -> progress. Frameworks are DATA (rule 11), so a new discipline is rows, not code. license_tier: ORIGINAL No hw writes (Rule 26).
