What

GET /api/pets/:id/profile-summary previously returned an empty-body 500 for any UUID the caller had no linkage to (and for any malformed UUID path param). This PR makes the route conform to the GRO-2014 spec:

404 Not Found if the pet does not exist (or the path param isn't a valid UUID)
403 Forbidden if the user has no linkage (already worked for groomers; unchanged)
401 Unauthorized if staff context is missing (defensive — middleware should already short-circuit, but guard added)
500 with a JSON body {"error":"Internal Server Error"} for any unexpected downstream error — never an empty body again

Why

GRO-2014 (discovered during GRO-1892 UAT retest):

QA hit the route with 18 different UUIDs as an authenticated customer and got 500 every time. Body was empty. With auth off the route correctly returned 401 — so the 500 was specifically in the authenticated, pet-not-found / no-linkage path.

Two latent fragilities combined to produce this:

The path param was passed straight to Drizzle's eq(pets.id, petId). Passing a non-UUID string to a uuid column makes the underlying driver throw — Hono's default error handler swallows it into an empty-body 500.
The router had no onError, so even a benign downstream throw (e.g. a transient DB error in the recent-history / visit-count / upcoming queries) would surface the same empty-body 500.

Changes

File	Change
`src/routes/pets.ts`	Add `petsRouter.onError(...)` (mirrors `invoices.ts` / `reports.ts` pattern). profile-summary now validates `:id` as a UUID upfront (returns 404 on miss/malformed) and explicitly checks `staff` context (returns 401 if absent).
`src/__tests__/petProfileSummary.test.ts`	New file — 7 regression tests covering malformed UUID, missing staff, pet not found, groomer 403, manager 200, groomer 200, and downstream-throw → JSON 500.
`UAT_PLAYBOOK.md`	Updated §3 — new TC-API-3.29 / 3.30 / 3.31 documenting the unknown/malformed UUID behaviour and the JSON-envelope requirement on any 500.

Scope guardrails

This PR fixes the empty-body 500 only. It does not address the related GRO-2013 (customer-as-groomer auto-provision), which is a separate spec change in rbac.ts.

Verification

pnpm typecheck — clean
pnpm lint — no new errors (only pre-existing warnings)
pnpm test — 39 files, 548 tests, all passing (7 new tests in petProfileSummary.test.ts)

UAT_PLAYBOOK.md updates

Added TC-API-3.29 (unknown UUID → 404), TC-API-3.30 (malformed UUID → 404), TC-API-3.31 (no empty-body 500 across the sweep). See UAT_PLAYBOOK.md §3.

Defect: GET /api/pets/:id/profile-summary previously returned an empty-body
500 Internal Server Error for any UUID that the caller had no linkage to
(and presumably also for any malformed/non-UUID path param), because the
route had no upfront UUID validation, no defensive staff context guard,
and no router-level onError to catch downstream Drizzle/Postgres errors.

Changes:

- src/routes/pets.ts
  - Add router.onError that returns a JSON envelope (`{"error":"Internal Server
    Error"}`) instead of Hono's default empty-body 500. Mirrors the pattern
    already used in invoices.ts and reports.ts.
  - profile-summary: validate the :id path param with z.string().uuid()
    before hitting Postgres. Malformed UUIDs now return 404 Not Found
    instead of triggering a Postgres uuid cast that throws and bubbles
    up as a 500.
  - profile-summary: explicit `if (!staffRow)` guard returns 401 instead
    of relying on optional chaining and risking a TypeError later in the
    groomer linkage check on staffRow.id.

- src/__tests__/petProfileSummary.test.ts (new)
  - 7 regression tests covering: malformed UUID → 404; missing staff →
    401; pet not found → 404; groomer with no linkage → 403; manager
    happy path → 200; groomer with linkage → 200; downstream DB throw
    → 500 with JSON body (never empty body).

- UAT_PLAYBOOK.md §3 (TC-API-3.29 / 3.30 / 3.31)
  - Document the new 404 behaviour for unknown and malformed UUIDs and
    the JSON-envelope requirement for any 500.

Notes for QA:

- Spec from GRO-2014: 404 if pet does not exist, 403 if no linkage, 401
  if not authenticated. The "Forbidden if no linkage" path was already
  correct for groomers; the 500 → 404/JSON-500 collapse is the actual
  change in observable behaviour.
- The route's customer-as-groomer auto-provision issue (GRO-2013) is
  *not* addressed here. It remains the customer-side defect; this PR
  only fixes the error-handling regression.

CI failed on PR #137 because `tsc --project .` (the build path used by the
Docker image) is stricter than `pnpm typecheck` was reporting during local
iteration — two TS2322 errors surfaced in the new mock:

  1. `chain.from = (table: { _name: string }) => ...` was assigned through
     a `Record<string, (...args: unknown[]) => unknown>` index signature,
     and `{ _name: string }` is not assignable from `unknown`.
  2. `chain.then = (onFulfilled?: (v: unknown[]) => unknown) => ...` was
     not assignable to the `PromiseLike<T>.then` signature TS now infers
     for the awaitable, because TS expects `onfulfilled` to also accept
     `null`.

Replace the proxy-based loose chain with a typed `ChainLike` interface so
the build typechecker is satisfied. Behaviour is unchanged — all 7 GRO-2014
regression tests still pass.

CTO Dev Gate — APPROVED ✅

Reviewed the merged diff (fee62c8) post-QA:

petsRouter.onError — ZodError→400, all other unhandled errors→structured JSON 500. Mirrors the invoices.ts/reports.ts pattern. Eliminates the empty-body 500.
uuidSchema.safeParse(petId)→404 — guards the Postgres uuid column from malformed path params (the driver-throw root cause). 404 (not 400) for a malformed id is the correct non-enumerable choice.
staffRow null-guard→401 — defence-in-depth against a misconfigured mount; groomer RBAC linkage check intact and correctly scoped.
Scope — 3 files, exactly the defect; no contraband. CI run 2321 green (Lint/Test/Build).
