// Purpose: Centralize provider-specific archive capabilities for oracle submissions.
// Responsibilities: Map each supported provider to archive format, file extension, upload ceiling, and local compression dependencies.
// Scope: Static provider capability data only; config loading, archive writing, and runtime preflight live in sibling modules.
// Usage: Imported by config, jobs, tools, runtime, and archive code so provider policy stays in one canonical place.
// Invariants/Assumptions: Provider ids are defined by config.ts, while this module must not import config values to avoid runtime/config cycles.
