Reuses the existing identity/teams, identity/agents, and
orchestration/hierarchy scaffold directories per doc 07's documented
module placement. Key decisions: last-write-wins availability (not
optimistic locking — operational telemetry, not a durable record),
compound-unique skill upsert, cycle detection only on reparenting edits
(not creation, which can't form a cycle), and a capability-eligibility
read path that composes hierarchy scope with caller-supplied skills
while deliberately excluding availability per doc 05's own ordering.
