v1.0.5 (2026-09-23) — Missing WHAPI_API_KEY / caller whapiApiKey finishes SUCCEEDED INVALID_INPUT (user omission), not FAILED. Present key rejected by Whapi (401/403) → CONFIG_ERROR; other provider outages → UPSTREAM_FAILED. Optional BYOK input whapiApiKey (isSecret).

v1.0.4 (2026-08-21) — clearer CONFIG_ERROR when WHAPI_API_KEY is missing; document that TikHub/ScrapeCreators/SociaVault have no WhatsApp number-check route; never invent validation rows.
