Multi-User Mode — removed (out of scope)

FlintTrade is a personal-use, single-operator trading workstation: the operator is the user is the data principal. The multi-user CRUD scaffold (/api/v1/users/*, an admin/trader/viewer account manager) was removed on 2026-06-10 as overscope — it added a hosted-SaaS surface this project deliberately does not have, and it was opt-in code that nothing enabled.

If multi-user / multi-tenant support is ever needed, it should be redesigned around the gated-principal model (the selector-bound RequestContext + broker account_acls that already authorise every order) rather than restored as a parallel user table — full per-user workspace, secret, and broker-credential isolation, plus audit review and operational runbooks, would be prerequisites before any live-broker multi-user deployment.

The removed code remains available in git history (removed 2026-06-10) for reference.
