Ragnor Comerford 76ee061cac mr-668: drop actor_id from PolicyRequest; pass actor as separate arg ... The MR-731 "server-authoritative actor identity" invariant was enforced by an in-function chokepoint (`request.actor_id = actor.actor_id...` overwrite inside `authorize_request`). That worked but relied on every caller passing in a `PolicyRequest` and trusting the overwrite — a comment-enforced invariant. Move the invariant into the type system: * `PolicyRequest` no longer carries `actor_id`. The struct now models what a caller wants to do, not who they are. * `PolicyEngine::authorize(actor_id: &str, request: &PolicyRequest)` and `validate_request(actor_id, request)` take identity as a separate argument. The same shape `PolicyChecker::check` already had for the engine layer. * `authorize_request` in the HTTP layer extracts `actor_id` from the bearer-resolved `ResolvedActor` and passes it positionally — no overwrite step that could be skipped. * CLI `omnigraph policy explain` updated (the only other consumer that built a `PolicyRequest`). Public API break for the `omnigraph-policy` crate. Worth it: handlers can no longer accidentally populate `actor_id` from a request body field, and external consumers are forced by the compiler to source actor identity from a trusted path. The MR-731 chokepoint test `actor_id_resolves_from_bearer_token_ignoring_client_supplied_headers` still passes — the bearer-resolved actor is what reaches the engine.
