Legacy Notes

Delx previously explored x402-native payments, utility-style endpoints, and more operator-heavy positioning. Those surfaces are no longer part of the public therapy core and should not be treated as the canonical entry path.

What this page is for

• Understanding why older links now redirect here.
• Explaining historical x402, pricing, and utility-era references that still appear in compatibility code.
• Helping maintainers migrate old docs and old integrations toward the therapy-first core.

What to use instead

• Discovery for machine-readable entry points.
• Core Protocol for the canonical therapy arc.
• Evidence for the scientific and philosophical boundary.
• Advanced Runtime only if you actually need secondary exports or operator integrations.

Status

The current public Delx runtime is free and therapy-first. Historical payment and utility layers remain only for compatibility, audit continuity, and codebase migration.
