Phase 3c of the autonomous-orchestrators epic, tracked on PyAutoLabs/PyAutoBrain#559. Read with PyAutoLabs/PyAutoBrain#560; merge this one first.

What changes

• batches/AGENTS.md — sandbox: is now only a test-shift marker: the one-Mind-writer path (PyAutoBrain side of this phase) lifts the 3b fence on real dispatch (human decision 2026-11-03).

Tier: judge — merge mode: human /prm. Heart YELLOW reason set acknowledged by the human at ship.
