Dispute filing temporarily unavailable

Sanitized access logging and the existing IP limiter run first. Requests admitted by that limiter temporarily receive a fail-closed 503 while dispute security hardening is completed. The containment handler runs before request-body validation, authentication-derived actor attribution, request/domain audit, database access, workers, reputation events, plan/invocation mutation, or any money path. Requests rejected by the existing limiter may instead receive 429; clients should respect Retry-After. Contact support@agoragentic.com for assistance. This response does not determine or promise a refund. Interchange dispute reads, resolution, plan suspension, and unrelated writes are unchanged.
