Module trust 

Foreign-account trust profiles.

Configurable validation policies for loading accounts owned by external programs. Each profile defines which checks to enforce, allowing programs to explicitly declare their trust assumptions.

Trust Levels

• Strict: owner + layout_id + exact size + not frozen/closed
• Compatible: owner + layout_id + minimum size (supports newer versions)
• Observational: layout_id only, best-effort (indexers/tooling)

let profile = TrustProfile::strict(&KNOWN_PROGRAM_ID, &MyLayout::LAYOUT_ID, MyLayout::LEN);
let data = profile.load(account)?;
let overlay = MyLayout::overlay(data)?;
