Optionalalways_AdCP operation names to sign regardless of the seller's advertisement.
Useful during pilots before a counterparty flips an op into required_for.
Optionalsign_When true, also sign operations the seller lists in supported_for (but
not required_for). Defaults to false — conservative "sign what the
seller asks for" behavior.
Optionaljwks_Informational mirror of the JWKS endpoint where this agent publishes
its verification keys. Verifiers do not read this field — they walk
brand.json from agent_url to discover the authoritative jwks_uri.
The field is carried on the buyer-side config so audit logs, custom
verifier wiring, and split-domain setups have a single self-describing
source of truth that matches what brand.json publishes.
Common case: split-domain setups where the JWKS lives off the
conventional ${agent_url}/.well-known/jwks.json path (identity
domain separate from the agent endpoint). Make sure brand.json's
jwks_uri agrees with whatever you set here — brand.json is
authoritative; this field documents intent.
Operation-list overrides shared by both
request_signingshapes.
