Validation (duplicate bundleId, bundle existence, project authorization, read-only state) is performed up front and any failure rejects the entire request before any write. The database insert of the resulting attachments is a single batched write, so the attachment rows are atomic. Rules-gateway propagation runs after the insert and is best-effort: if it fails the attachments remain persisted and the caller should retry — deduplication makes retries safe (already-attached items are skipped). This matches the behavior of the single-attach endpoint. ## OpenAPI ````yaml /api-specs/cloud/public-api.json post /api/governance/v1/rpc/bulk-add-attachments openapi: 3.0.3 info: title: Domino Public API description: Reference for Domino's public REST API endpoints. version: 6.4.0 x-catalog-key: nucleus servers: - url: https://mycluster.domino.tech description: >- Replace 'mycluster.domino.tech' with your Domino cluster hostname.
