"""ORCH-016 / TC-19 + AC-1..AC-5 authorship: status comments use per-agent bots.

When a status comment is posted by AgentLauncher._post_usage_comments, the
underlying plane_sync.add_comment must be invoked with ``author=<agent>`` so
plane_sync._headers_for(<agent>) picks the agent's bot token
(PLANE_BOT_TOKENS[role]) — falling back to PLANE_HEADERS when the bot token
is empty / role unknown. Comment FORMAT changes (ORCH-016) must not affect
that authorship contract.
