- DbBase.FindRequired / Client.FindByNameRequired now throw the
domain-specific ObjectNotFoundException (NHibernate lineage; Rails
equivalent: ActiveRecord::RecordNotFound) on a lookup miss; the
no-context case stays InvalidOperationException (configuration error)
- Console demo catches the new type; tests (18)/(21) assert it,
(19)/(23) keep InvalidOperationException with rationale comments
- scripts/run-console.sh delegates to dotnet.sh; run-console.ps1 is
the Windows/PowerShell counterpart (mise-first, repo-root cd)

DbBase.Find<T> now uses db ?? Context, and Client.FindByName's context
parameter becomes optional — call sites read like Client.FindByName("Jane
Doe") without context threading. A null result now overwhelmingly means
"no match"; the residual "no context configured at all" ambiguity is
documented in remarks as part of the ActiveRecord-leak cost this exercise
illustrates.
ActiveRecord pattern: expose a shared DbContext on DbBase so any
entity subclass can reach it without passing context through parameters.
The instance-level DbContext back-reference still works; the static one
provides a class-level global fallback.
Add the C# BEFORE situation: a fake-EF DbContext + DbBase that Client/Order
inherit, the active-record DbContext back-reference (the dependency leak),
navigation fix-up on Client.Orders, and a WebApp that consumes the domain
classes directly. Adds an empty After project so the solution shape is final,
and an xUnit BeforeTests suite covering the required assertions.
- db-subclass-to-dto.sln (classic .sln; SDK 10 defaults to .slnx which breaks run-tests.sh)
- src/Before: DbBase, DbContext, Client (+ClientOrders fix-up), Order, WebApp
- src/After: empty placeholder (filled in Yak 02)
- tests/BeforeAfter.Tests/BeforeTests.cs: 8 tests (7 required + 1 companion)
