Defense-in-depth for the spawn_agent human-role chokepoint (d31d6719).
The chokepoint structurally guarantees no CEO/prompter/secretary container
can ever spawn — every dispatcher goes through spawn_agent. But two
dispatchers resolve an arbitrary assigned_to and spawn it with only a
None/unknown-role filter, so a human-assigned task would reach the
chokepoint and RAISE: caught by the per-dispatcher try/except, but it
aborts that dispatcher's whole tick (stalling other respawns behind the
mis-assigned task) and error-logs every cycle. The other dispatchers are
already safe by whitelist/hardcoded slug (blocker_resolver_slug returns
None for non-PM/non-BOARD; escalation/approval use whitelists; marketing
and audit hardcode their non-human slug).
- _claimed_task_needs_agent: return None for a CEO/prompter/secretary
assignee — no container to respawn, and do NOT release a human-owned
task to pending (that would re-route it to a PM). Leave it for the human.
- _dispatch_pm_review_work (assigned branch): skip a human-only assignee
so a CEO-assigned awaiting_pm_review task neither spawns nor aborts the
dispatcher's tick.
Audited all target-iterating dispatchers; only these two lacked a filter.
Regression tests cover both skips.
