Service-layer components that sit alongside the contractile trident but are not themselves verbs. Per ADR-001 (2026-04-18), K9 lives here rather than under contractiles/ so the contractile directory stays a pure six-verb set (intend, trust, must, bust, adjust, dust).

• k9/ — K9 self-validating templates and validators.

For the verb contractiles themselves, see .machine_readable/contractiles/.
