* refactor(orchestration): send every agent-to-agent message through one sendAgentTurn The structured mail-pointer lane and the structured worker preamble each carried a copy of "send, wait out a pending start, read the verdict", and four dispatch-preamble sites typed into a terminal directly. They now share sendAgentTurn, built from host.send, the host's settlement waiter and sendTerminalAgentPrompt. Every caller passes delivery 'now', so nothing sends differently; a source-scan ratchet keeps new direct sends out. * test(orchestration): the refusal fixture uses a real wire refusal code * fix(orchestration): derive the send fingerprint inside sendAgentTurn and pair target with turn A `queue` send was refused by a real host: callers supplied a fingerprint over the body alone while the host digests body and delivery. sendAgentTurn now builds the envelope with the composer's own builder (extracted to structured-agent-session-send-mutation), so the fingerprint is always over exactly the fields sent; `now` sends keep the identical digest. The pointer lane no longer carries a fingerprint it cannot get right. sendAgentTurn takes one argument, a union on kind that carries its own target and turn, resolved by an exhaustive switch; the terminal turn names its purpose (only the dispatch preamble today) instead of every terminal send inheriting the task lead line. A queued outcome keeps the host's draft receipt, and both structured callers read outcomes exhaustively with unchanged behaviour. The boundary test now also fences direct structured host sends, catches optional, bracket and bound member uses, has a planted-offender self-test, and pins the unmoved terminal mail pointer and agent-teams tmux senders. * fix(orchestration): keep federation.ts under max-lines and satisfy prefer-template in the send ratchet * fix(orchestration): wait on the answered submission's id when a replayed queue turn was already handed off * test(orchestration): pin that a replayed queue turn waits for its hand-off to settle * test(orchestration): fence call-result and cast host sends, raw terminal writes and the launch-prompt helpers
