Rescope PRACTICE.md into PRACTICE-REGISTRY.md: it now owns only the
practice-slug lineage registry, not product positioning or CDLC doctrine.
Update all references (schema, validate-practice-citations.sh, bats test,
architecture-terms.md, documentation-index.md, aggregate.go comment).
Introduce the Context Density Rule as a canonical domain concept: every
high-value context token carries intent, boundary, evidence, decision,
constraint, or next action. New domain entry context-density-rule.md (+
codex mirror). Thread the BDD/Gherkin + DDD + Hexagonal + TDD narrow waist
through cdlc.md, README.md, PRODUCT.md, GOALS.md, and the rpi/domain/
post-mortem skills. Sync codex artifacts.
