- Upload — A handle representing a single file upload flow. Clients call CreateUpload to receive a short-lived presigned URL, PUT the file directly to object storage, then reference the upload by id when creating or updating resources that accept binary content. Uploads are one-shot: once consumed by a creating or updating resource the upload transitions to UPLOAD_STATUS_CONSUMED and cannot be reused. Unused uploads expire and are garbage-collected.
  - `metadata` ResourceMetadata, required — Standard metadata for persistent, named resources (e.g., agents, tools, prompts)
    - `id` string, required — Unique identifier for the resource (prefixed ULID, e.g., "agent_01HXK...")
    - `accountId` string, required — Account this resource belongs to for multi-tenant isolation (prefixed ULID)
    - `workspaceId` string, required — Workspace this resource belongs to for organizational grouping (prefixed ULID)
    - `name` string, required — Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly
    - `externalId` string — External ID for the resource (e.g., a workflow ID from an external system)
    - `labels` object — Key-value pairs for categorization and filtering. Values are 0-63 alphanumeric characters with "-", "_", or "." allowed between; keys follow the same shape and additionally accept an optional DNS-subdomain prefix (e.g. "cadenya.com/") of at most 253 characters. Examples: {"environment": "production", "team": "platform", "version": "v2"}
    - `profileId` string, required — ID of the actor (user or service account) that created this resource
    - `createdAt` string, date-time, required — Timestamp when this resource was created
    - `updatedAt` string, date-time — Timestamp when this resource was last updated
  - `spec` UploadSpec, required
    - `filename` string, required — Client-supplied filename. Used for audit and display only; does not control the object's storage path.
    - `contentType` string, required — MIME type the client will send. Baked into the presigned URL's signature — the PUT must match exactly or object storage will reject it.
    - `sizeBytes` string, required — Expected size of the upload in bytes. Baked into the presigned URL as a Content-Length constraint.
  - `info` UploadInfo, required
    - `uploadUrl` string — Presigned PUT URL. Short-lived. The client must PUT with the exact Content-Type declared in the spec, and the body length must match size_bytes.
    - `uploadUrlExpiresAt` string, date-time — Absolute time at which upload_url stops working.
    - `status` 'UPLOAD_STATUS_UNSPECIFIED' | 'UPLOAD_STATUS_PENDING' | 'UPLOAD_STATUS_COMPLETE' | 'UPLOAD_STATUS_CONSUMED' | 'UPLOAD_STATUS_EXPIRED', enum — Lifecycle state. Transitions PENDING → COMPLETE (storage confirms the object exists) → CONSUMED (a resource referenced this upload), or → EXPIRED (URL elapsed without a PUT).
    - `createdBy` Profile — A profile identifies a user or non-human principal (such as an API key) at the account level. Profiles are account-scoped and can be granted access to multiple workspaces.
      - `metadata` AccountResourceMetadata, required — AccountResourceMetadata is used to represent a resource that is associated to an account but not to a workspace.
        - `id` string, required — Unique identifier for the resource (prefixed ULID, e.g., "apikey_01HXK...")
        - `accountId` string, required — Account this resource belongs to for multi-tenant isolation (prefixed ULID)
        - `name` string, required — Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly
        - `externalId` string — External ID for the resource (e.g., a workflow ID from an external system)
        - `labels` object — Key-value pairs for categorization and filtering. Values are 0-63 alphanumeric characters with "-", "_", or "." allowed between; keys follow the same shape and additionally accept an optional DNS-subdomain prefix (e.g. "cadenya.com/") of at most 253 characters. Examples: {"environment": "production", "team": "platform", "version": "v2"}
        - `profileId` string, required
        - `createdAt` string, date-time
      - `spec` ProfileSpec, required — Configuration for a profile.
        - `email` string — Email address of the profile. Required and unique within an account for user profiles.
        - `name` string — Display name (e.g., "Bobby Tables").
        - `type` 'PROFILE_TYPE_UNSPECIFIED' | 'PROFILE_TYPE_USER' | 'PROFILE_TYPE_API_KEY' | 'PROFILE_TYPE_SYSTEM', enum, required — Whether this profile represents a human user, an API key, or a system principal.
