bostonaholic Single Source of Truth
Define every rule, constant, and schema once; make other surfaces consult it, or name one canon and deterministically pin required copies.
Why: The second copy is the one that drifts.
- Name owners at deference points: "the schema is canonical in — consult that skill rather than restating it."
- Keep constants where they execute; make prose cite them without repeating values.
- Give deliberate template or byte-identical duplication a consistency gate and a comment naming the canon.
- When summary and source disagree, the source wins; identify the authority wherever both exist.
- Restate at most one line for readability; cite the owner for longer content.
