presentations

Shared trusted-host validation for Presentation persistence implementations.

Structs

AttachmentMeta

Metadata for a file uploaded during a chat session. The actual bytes live on disk at file_path; served via GET /api/attachments/{id}.

CostEntry

One durable cost-budget spend event (CH-07). Mirrors cost_budget::BudgetScope/record()’s in-memory accounting, but as a persisted, append-only history entry rather than an aggregate.
