Capture

The YY Method should remain usable directly from the website.

Why

This decision makes Decision Tree easier to build because the website teaches the doctrine and the app operationalizes the ritual.


Why-Not

The rejected path would make preserve the Method Outside the App too easy to treat as an implementation detail instead of a public boundary. The ADR preserves the tradeoff explicitly so later product work cannot silently widen authority.

Commit

Decision: The YY Method should remain usable directly from the website.

GPT can help a person think. The YY Method app reduces friction around using the method and restores friction at the moments where judgment is most likely to become premature.

This decision makes Decision Tree easier to build because the website teaches the doctrine and the app operationalizes the ritual.


Confidence: Medium-high for public architecture; implementation details remain private and subject to launch evidence.
