Export Center — format record (service retired, folded into OfflineKit)

Pointer stub. The Export Center service retired on 2026-09-12 (SPRINT_20260722_025 OK-10): export-web/export-worker are frozen at src/__Obsoleted/ExportCenter/, the application layer lives at src/OfflineKit/__Libraries/StellaOps.ExportCenter.Application (namespaces kept on purpose), and the export plane is served by offlinekit-web under /api/offlinekit/v1/**. The predecessor database stellaops_exportcenter and role exportcenter were dropped on 2026-09-14 after parity verification.
Read OfflineKit for topology, runtime, configuration and operations. This folder keeps only the documents that describe FORMATS and PROTOCOLS the consolidated service still produces byte-for-byte. The retired dossier pages (architecture, consolidation design, API reference, implementation plan, overview, module contract, the trivy adapter record) are frozen at docs-archive/modules/export-center/ and describe the pre-consolidation service; they are history, not current truth.

What is no longer here

openapi/ — the retired export-web specification at the bare /v1/exports paths (archived). A live OfflineKit specification is not yet generated (SPRINT_20260722_025 D-OK10-5); the routes are documented in ../offlinekit/architecture.md.
Runtime, database, compose and doctor detail — see OfflineKit.
