# Task 9 Report — `publicApi.ts` tipos actualizados

## Status
✅ **DONE** — typecheck passes with 0 errors.

## File changed
- `src/lib/publicApi.ts` (only this file; no consumers touched)

## Typecheck result
```
$ npm run typecheck
> agenda-pro@1.0.0 typecheck
> tsc -b --noEmit
```
**0 errors.** The changes are additive/loosening, so no consumer breakage:
- `PublicBusiness.auto_assign_specialist` (added required field) is safe — the only consumer reading `PublicBusiness` is `BookingPage.tsx`, which does not yet destructure this field (it'll be added in Task 12). Adding a required field to an interface does not error on existing readers; it only errors on object *literals* that lack it, and there are no literals of type `PublicBusiness` in the codebase (they come from `request<PublicBusinessResponse>`).
- `BookPayload.employee_id` made optional → strictly loosening; existing callers passing `employee_id` still typecheck.
- `BookResponse.appointment` widened with `employee_id`/`reasons` → existing readers of `employee_name` still work; new readers will be added in Task 12.

No consumer errors observed.

## Interface diffs (verbatim from plan)

### 1. `PublicBusiness` — added `auto_assign_specialist`
```diff
   require_deposit: boolean;
   deposit_pct: number;
+  auto_assign_specialist: number | boolean;
 }
```

### 2. `BookPayload` — `employee_id` now optional
```diff
 export interface BookPayload {
   service_id: number;
-  employee_id: number;
+  employee_id?: number;
   start_at: string;
   client: BookClient;
 }
```

### 3. `BookResponse.appointment` — added `employee_id` + `reasons`
```diff
 export interface BookResponse {
   appointment: {
     id: number;
     start_at: string;
     price: number;
     service_name: string;
+    employee_id: number;
     employee_name: string;
+    reasons: string[];
   };
   business: { name: string; currency_symbol: string };
   client_created: boolean;
 }
```

## Consumer errors
None. (Plan's Step 2 note had anticipated possible errors in `BookingPage.tsx`, but none materialized — the optional `employee_id` and the widened `BookResponse` are backward-compatible with the current consumer code, which will be properly updated in Tasks 11–12.)

## Concerns
None. Ready for Tasks 10–12 to consume these new types.
