Short write‑ups of problems we hit running a real commerce operation and what we changed in the code because of them. No product announcements; just the reasoning.
Staff access in aiku is granted by job position — "dispatch clerk in the Spanish warehouse", "customer‑service supervisor for the UK shop" — not by ticking permissions. Positions expand to roles, roles to permissions, all scoped to the group, organisation, shop or warehouse they name. Why we chose that, how a permission is checked in the same place for the UI, the API and the MCP server, the "team id" that makes it all silently false if forgotten, and the things we refuse to do with an admin flag.
