Duplicate-Control Rules

Do not create a v5 note by renaming or overwriting a LEED v4 foundational note.
Compare the candidate with every listed possible duplicate before drafting.
Prefer one atomic note per engineering idea; keep rating-system-specific requirements in version-labeled sections or separate notes when they diverge.
Mark current_requirements_verified: true only after the comparison is documented.

Batch History

Batch 01 established planning, verification, feedback, and risk concepts. Batch 02 added energy, air, thermal, and water system concepts while preserving source gates and postponed atomic child concepts.
