The design record claimed PR 1 deletes RuntimeAgentRowStore, drops the
retained-versus-hook reconciliation, stamps terminalHandle on OSC rows, and
tags rows with a source field of 'structured-host'. None of that is true of
the shipped code: the retained store and its reconciliation are still in
place, and the row field is structuredHost: 'held' | 'owned'.
AGENTS.md points every future contributor here before they touch agent
status, so split the roadmap into the 1a that landed and the 1b that has not,
and name the fields the code actually writes.
