Telegram allowlist authorization could match on @username (mutable/recyclable) instead of immutable numeric sender IDs.

Operators who treat Telegram allowlists as strict identity controls could unintentionally grant access if a username changes hands (identity rebinding/spoof risk). This can allow an unauthorized sender to interact with the bot in allowlist mode.

Telegram allowlist authorization now requires numeric Telegram sender IDs only. @username allowlist principals are rejected.

A security audit warning was added to flag legacy configs that still contain non-numeric Telegram allowlist entries.

openclaw doctor --fix now attempts to resolve @username allowFrom entries to numeric IDs (best-effort; requires a Telegram bot token).

Thanks @vincentkoc for reporting.
