MVP browser acceptance runbook

Current contract: ADR-046

The previous runbook split acceptance into an immediate client send and a later Expert release because the old runtime held every agent reply. That behavior is retired, so the old instructions have been removed.

For every browser acceptance case:

1. Use a fresh conversation.
2. Send the real user message and any real attachments through the client portal.
3. Require the successful Hermes reply to appear without Expert release, confidence/risk review, approval, or a synthetic holding message.
4. Reload and prove the canonical SessionDB transcript persists.
5. Record browser-visible pass/fail evidence and warm/cold time-to-reply.
6. Treat a real agent failure as a failure; do not accept a canned fallback.

The release gate is the fresh Percy 01–10 browser pass described in ADR-046, plus the runtime, transcript, tool, and supervisor verification named there.
