A stable file model
Assets, versions, metadata, lifecycle, and product references use one tenant-aware contract.
Media owns upload intent, file metadata, versions, processing state, storage-provider coordination, and controlled delivery—while file bytes stay in customer-owned object storage.

A short-lived delivery path is issued for an allowed asset
Product outcome
Customer files need ownership, tenant context, lifecycle state, access rules, and a reliable path from upload to delivery. Media keeps that product logic together instead of spreading it across frontend uploads, bucket conventions, background jobs, and provider URLs.
Assets, versions, metadata, lifecycle, and product references use one tenant-aware contract.
Clients send bytes directly to the configured object store through short-lived upload instructions.
Applications request access through the service instead of exposing permanent storage paths.
01 / Domain capabilities
Initiate upload sessions and let clients transfer bytes to the configured object store without proxying large files through the application backend.
Keep product metadata, ownership, lifecycle, active versions, and entity references behind one queryable domain.
Represent asynchronous readiness, derived outputs, and failure states without asking the frontend to infer them from storage.
Generate short-lived access paths for originals or renditions after the product has applied its permission rules.
02 / Product workflow
Create the file and version records with tenant, owner, type, size, and product context.
Use the returned upload instructions to send file data directly to customer-owned storage.
Confirm the transfer and follow explicit lifecycle states while configured processing runs.
Request a short-lived download or rendition path when an authorized workflow needs the file.

}Asset, version, ownership, lifecycle, storage, and processing records remain queryable independently of raw bytes.
The service coordinates customer-selected object storage without becoming the file-byte proxy.
Upload completion, processing, readiness, failure, and delivery use explicit product states.
04 / Where it fits
Manage contracts, evidence, applications, or customer documents with stable metadata, versions, and controlled access.
Represent uploads and derived outputs through explicit lifecycle states while the product remains independent of storage paths.
Connect attachments to Submissions, support workflows, or domain records without rebuilding upload infrastructure for each module.
Ownership model
The source license, update term, support boundary, and customer-cloud responsibilities remain explicit. Missing domain work can be scoped as a custom module instead of hidden in a roadmap promise.
