Note

Clarifies delegation scope parameters across guides and reference, adds allowed/exact calldata details and examples, and links guides to their scope references.

• Guides:
  • Function call: Clarifies targets/selectors; documents internal caveat enforcers; adds link to reference/delegation/delegation-scopes.md#function-call-scope; expands example to include to, from, and environment; adds sections with examples for allowedCalldata and exactCalldata.
  • Spending limits: Refines wording; adds links to each scope’s reference; clarifies native token scopes default exactCalldata to 0x and optionally support allowedCalldata/exactCalldata; fixes minor phrasing (time-based).
  • Ownership transfer: Notes internal enforcer and links to reference/delegation/delegation-scopes.md#ownership-transfer-scope.
• Reference:
  • Caveats: Normalizes wording around calldata (drops superfluous backticks) and minor description tweaks.
  • Delegation scopes: Expands parameter docs for allowedCalldata/exactCalldata (including defaults and selector constraints); tidies examples/comments.
