Services now return entities; endpoints (and the agent toolsets) map to
*Response records instead of services building wire DTOs themselves.
Also brings in the outline-import agent, MCP tool, ledger and web dialog
that were already in progress on disk.
Not-found lookups return null/false instead of throwing NotFoundException
across all services — a missing row is expected control flow, not an
exceptional condition. NotFoundException stays for embedded precondition
checks inside mutations (missing parent, invalid foreign reference).
Guard (copied from mic-check) enforces required arguments at the top of
every service method. A ported IModelValidator<T> framework validates
every request DTO at the API layer via a new ValidationEndpointFilter,
returning a 400 with field-level messages; services re-run the same
validator and throw for direct callers that bypass the API.
Endpoints translate null/false into 404 via a new ToApiResult() helper.
The agent toolset boundary translates the same nullable/bool results
into the tool-error text the model already expected.
Three things the outline could not express before:
Main vs supporting. A new CharacterImportance sits alongside CharacterRole
rather than inside it — role is the part a character plays (protagonist,
mentor, foil), importance is how much of the book they carry, and a mentor can
be either. Characters start Supporting and get promoted. Listings put main
characters first.
Character arcs. A main character's arc is a flat ordered list of stages, the
same shape as a chapter's beats and for the same reason: an arc is a sequence
of changes, not a tree. A stage can be pinned to the chapter where it lands.
Nothing refuses an arc on a supporting character — demoting someone should not
delete their work.
Open questions. What the writer has not decided yet, hanging off a chapter
outline, a character, both, or neither. They can be resolved, reopened or
deleted, and resolving can append the decision to the notes of whatever the
question was attached to, so it lands where the writer will re-read it.
Resolved questions drop off the list unless asked for.
Also adds GET /api/characters/{id}/beats — every beat a character appears in,
in manuscript order, carrying each beat's chapter so the character page can
link straight into that chapter's outline.
Deletes are deliberately asymmetric: deleting a chapter unpins arc stages and
detaches questions rather than taking them, because a plan outlives a decision
about where the chapter break falls. Deleting a character or project does take
their arcs and questions.
All three capabilities are surfaced in the REST API, the agent toolset and the
MCP server, per the one-source-of-truth rule.
Two things worth flagging in the migration: EF's generated default for the new
Importance column was an empty string, which does not parse back to a
CharacterImportance and would have faulted every read of an existing dossier —
it now defaults to Supporting, verified by migrating a database seeded on the
old schema and reading the row back through the API. And the earlier migrations
were renamed to the namespace EF derives from the output folder, so future
`migrations add` runs stop drifting.
72 tests pass (28 new). The endpoints were also exercised over curl end to end:
arc stages resolving their chapter, a character's beats across chapters, and a
question attached to both a chapter and a character resolving into both sets of
notes.
