26 files with Zod schemas, 27 safeParse calls. All POST/PATCH handlers now validate input: - Missing required fields → 400 with structured error - Invalid types (string vs number) → 400 - Out-of-range values (probability >100, negative amounts) → 400 - Valid data still works (behavior preserved) Pattern: schema.safeParse(await req.json()) → 400 on failure
