REST API endpoints for Copilot code review

Request a Copilot code review for a pull request

Requests a Copilot code review for a pull request. Every call expresses intent to start a new review: if no Copilot review has been requested yet, an initial request is created; if the most recent Copilot review has already completed (including if it was later dismissed or superseded), a new request is created automatically to continue the review lifecycle. If a Copilot code review request is already pending for the pull request, no new request is created and the response is 409.

If the actor or repository is not eligible for Copilot code review, the actor has no quota remaining, or the licensing organization is unavailable, no request is created and the response is 422 with a stable failure_reason. A review_effort is accepted only when that effort level is available for the repository and actor; an unrecognized or unavailable review_effort returns 422 with failure_reason INVALID_REVIEW_EFFORT. If the actor, repository owner, or requesting application owner has been flagged, the response is 403 with failure_reason ACTOR_FLAGGED. If the per-actor or per-owner request rate limit is exceeded, the response is 429 with failure_reason RATE_LIMITED. If Copilot code review cannot be serviced right now, the response is 503.

Existing human and team review requests on the pull request are left unchanged.
