-## Architecture Decision Records (ADRs)
-
-**Every non-trivial AI-assisted PR must include an ADR.**
-This documents what the AI understood so reviewers can verify assumptions and future contributors can build on it.

-| Scope | Directory |
-|-------|-----------|
-| gno.land | `gno.land/adr/` |
-
-**Naming**: `pr<number>_<description>.md`.
-Use `prxxxx_` if PR number unknown.
-
-**Include**: context, decision, alternatives considered, consequences.
-See `gno.land/adr/` for examples.
-Match detail to complexity.
-
-Skip ADRs for: trivial bug fixes, formatting, simple tests, docs-only changes.
