spec::gal · 7 trust rules · 7 typed records · 7 RPC methods

GAL Specification.

The Global Anchor Layer enforces seven trust rules on every privileged path. Each rule has a typed error code. Failures fail closed — there is no silent fallback. Seven typed records, seven RPC methods, fourteen typed transaction variants under the `tower` cargo feature.
