Smoke-8 follow-up. Two issues in _write_agent_briefing:
1. _build_tool_load_block was scraping role prompts for a "## Load on
spawn" section that doesn't exist in any role file. Returned "" for
every role → no ToolSearch directive in the briefing. Combined with
weak models skipping the system-prompt-layer directive (#144), the
agent's first action was Edit → "not enabled in this context."
Fix: per-role tool list lives in the orchestrator (mirrors
factories._base.py). Pre-renders the directive directly. developer
and documenter get Edit + Write; QA/PMs/board get the common
read-only set. 7 tests pin the contract.
2. The briefing's "Terminal tools (how to exit cleanly)" section still
listed pre-gateway verb names: roboco_agent_idle,
roboco_task_substitute, roboco_task_escalate,
roboco_task_submit_qa, _qa_pass/fail, _docs_complete, _complete.
Same rename pattern as #145's _TERMINAL_TOOLS set. Updated to:
i_am_idle, i_am_blocked, unclaim, i_am_done, pass, fail,
i_documented, complete, submit_up, escalate_up, escalate_to_ceo.
The agent now reads the same directive in two places (system prompt +
session briefing) — the second touch point catches weak models that
skip the first.
