Live Telegram direct turns can produce a current-turn commentary answer after tool use, then a stale final_answer copied from the previous turn. The stale replay guard currently only promotes commentary if it contains a synthetic QA anchor, so real user prompts fall through to a user-visible retry notice.

Acceptance:

• Promote substantive current-turn commentary when final_answer is stale/repeated.
• Keep progress-only commentary such as "Working on it" suppressed.
• Add regression tests for unanchored real-user prompt behavior.
• Deploy to Zeus and verify via the live Telegram path.
