Defines the target architecture for eliminating direct ApplicationDbContext
injection from controllers. Documents the three-tier model (generic repo,
typed domain repos, read services), the 6 typed repository interfaces to
build, the 2 reporting service interfaces to build, permanent exceptions,
and the 4-phase migration roadmap with per-controller checklist.
CLAUDE.md updated with the hard rule and tier quick-reference so every
session and every team member sees the constraint immediately.
