Architecture Decision Records referenced from section 9 live in docs/adr/.

This documentation set reflects the system as of the vendored schema at @opencoachingformat/spec v1.2.0 (see shared/schema/PROVENANCE.md for the exact source ref). The prior brainstorming/design document at docs/superpowers/specs/2026-06-03-ocf-validator-design.md remains as historical record of the initial design process; this arc42 set is the maintained, current architecture reference going forward.
