A standalone mock of a SAP-shaped ERP/finance API — general ledger entries, cost centers, vendor invoices, and payment/settlement records — for the adev course tracks to consume as an external system dependency. It is the system of record for Portwell's Operations and Finance function.
Independent repo: no dependency on course-shared, the other mock-* repos, or any track repo.
Tracks that need it pull it in as a service dependency; this repo never depends on them back.
No track currently depends on this repo. It is scaffolded (via /adev:init) but not yet
chartered or implemented — run /adev:brainstorm to define its API surface and fixtures.
