Spec reviewer noted §6.3 was missed during Task 3 commit. The presenter
tests exist in code (sign-in / sign-up controller tests assert cookie
shape, not full use-case output); the changelog just didn't record it.
Pure docs change.
Per Plan 9 (spec R1-R28):
- Use cases: input + output schemas (signIn, signUp); input-only for
signOut (void output). Use case body validates output via
outputSchema.parse before returning.
- Controllers: receive `unknown`; safeParse with the use-case schema;
presenter (returning cookie) for signIn/signUp; void return for
signOut.
- New integrations/api/procedures.ts with authProcedure built via
defineErrorMiddleware([[InputParseError,"BAD_REQUEST"],
[AuthenticationError,"UNAUTHORIZED"], [UnauthenticatedError,
"UNAUTHORIZED"], [UnauthorizedError,"FORBIDDEN"]]).
- Router uses authProcedure + .input(xInputSchema) for every procedure.
- src/index.ts exports schemas + types + IUseCase/IController aliases.
- package.json gains ./ui subpath; src/ui/index.ts placeholder
(auth has no query builders today).
- New tests: R25 output-validation per use case (signIn, signUp);
R26 router error-mapping (UNAUTHORIZED on missing user,
BAD_REQUEST on schema fail).
Refactor log: §1, §2, §3.1, §3.2, §3.3, §5.1, §5.2, §6.1, §6.2

Factory takes [[ErrorCtor, TRPC_CODE], ...] tuples and returns a tRPC
middleware that translates matching domain errors to TRPCError. Discrim-
inates by instanceof; preserves original error as cause; unmapped
errors propagate (tRPC then wraps them as INTERNAL_SERVER_ERROR with
the original error as .cause — middleware does not interfere).
core-shared never enumerates feature errors — each feature passes its
own constructors in via integrations/api/procedures.ts (Tasks 3-7).
Also exports the `t` instance from trpc/init.ts so feature procedure
files can do t.procedure.use(...).
Also fixes tsconfig.json: rootDir set to "." and @/* path alias added
so test files using @/ resolve correctly under tsc --noEmit.

Empty section template plus the doc-update checklist that the
post-Plan-9 follow-up pass will work through (combined with the still-
pending Plan 8 items so docs are written once).
Spec: docs/superpowers/specs/2026-05-06-input-output-unification-design.md §10, R30.
