All 44 tests, same names, same coverage — verified by diffing the runner's test
list before and after.
The load-bearing change is fixture lifecycle. xUnit builds a new test-class
instance per test, so a `readonly TestDatabase _db = new()` field gave every
test its own database. NUnit reuses one instance for the whole class, so those
field initialisers and constructors would have shared a single database across a
class and let tests read each other's rows. Setup moved into [SetUp]/[TearDown]
via a new ServiceTestFixture base class, which also collapses the per-class
service wiring that was duplicated five times.
Assertions are now Assert.That with the constraint model:
Should().Be(x) -> Is.EqualTo(x)
Should().BeNull() -> Is.Null
Should().HaveCount(n) -> Has.Count.EqualTo(n)
Should().Equal(a, b) -> Is.EqualTo(new[] { a, b })
Should().BeEquivalentTo(..) -> Is.EquivalentTo(..)
Should().Contain("x") -> Does.Contain("x")
Should().OnlyHaveUniqueItems() -> Is.Unique
ThrowAsync<T>().WithMessage("*m*")
-> Throws.TypeOf<T>().With.Message.Contains("m")
FluentAssertions' `.Which` chains became plain indexed asserts, grouped in
Assert.Multiple so a failure reports every broken expectation in the case rather
than stopping at the first.
Because a framework migration can quietly produce vacuously-passing tests,
spot-checked four conversions by mutation — breaking the code under an async
Assert.Multiple block, a sync one, a Throws constraint, and a collection
ordering assert. All four failed as they should, confirming the assertions are
live and that NUnit bound the async lambdas to AsyncTestDelegate rather than
silently accepting them as async void.

The self-nesting outline tree was more structure than chapter outlining needs.
A chapter outline is now a paragraph plus a flat, ordered table of beats, and
tags do the cross-referencing that nesting was doing badly.
A beat is one row: a three-to-five word title, an optional character, what
happened, and what's next. Ordering is a SortOrder column within the chapter —
no parent pointers, no cycle guards, no recursive tree building. Reordering is
one call taking beat ids in the order wanted; ids left out keep their relative
position at the end rather than jumping to the front.
Beats plan, scenes carry prose. The two layers stay separate and a beat's
SceneId is the optional link between them, nullable in both directions —
deleting a scene ungroups its beats rather than deleting the plan, since that
is a decision about prose and not about the outline.
Tags are project-scoped, unique by name case-insensitively, and attach to
characters, chapters and beats through three join tables so cascade deletes are
the database's job rather than ours. Applying an unknown tag by name creates it,
which keeps tagging a single action; GET /api/tags/{id}/references returns
everything carrying a tag across all three kinds at once.
Removed: OutlineNode, OutlineService, its endpoints, agent and MCP tools, and
the Outline tab. Added: Beat and Tag with their services, endpoints, 5 agent
tools and 10 MCP tools, a beat table on the chapter page, a tag editor used in
three places, and a Tags tab for cross-referencing.
Migration drops OutlineNodes — the scaffolder's data-loss warning is the
intended removal, not an accident.
44 tests, up from 31.
