`agent.launch` could hand its initial text to a structured session but not to
a terminal. The contract already anticipated the terminal half — the
`handed-to-terminal` arm has been declared in agent-launch-intent.ts since the
receipt was written and had zero producers — and the executor's own docstring
recorded the assumption behind the gap: that a terminal's paste belongs to the
pane owner. That assumption is what this overturns. The host owns the PTY, so
it can write into one whether or not any window is open on it, which is why
mobile and the CLI got an agent and no prompt.
A terminal takes its prompt one of two ways, and which one is not a
preference. `argv` exists so multi-line and special-character text reaches a
CLI as one argument rather than keystrokes, and it has no readiness race
because the text is in the process's arguments at exec time. So an agent whose
CLI accepts a prompt argument gets it on the launch command, and only a
`stdin-after-start` agent — plus any reused terminal, whose process started
before the launch existed — is written to as a bracketed paste.
That fork is asked once. `agentPromptRidesLaunchCommand` is derived from the
same injection table `buildAgentStartupPlan` branches on, and
tui-agent-prompt-transport.test.ts pins the two against each other for all 37
agents, so adding an agent or changing its mode fails loudly instead of
silently dropping that agent's prompt.
Reused rather than rebuilt: `sendTerminalAgentPrompt` is the runtime's one
agent-prompt writer (bracketed paste, per-PTY serialization, lifecycle
generation pinning, per-agent submit timing, and local/WSL/SSH routing), gated
by `waitForTerminal('tui-idle')` — the same pair orchestration's worker
dispatch already delivers a preamble through. The agent-first create path
needed no new mechanism at all: `startupPrompt` already flows to
`buildWorktreeStartupForAgent`, and the launch had simply been stripping it as
a reserved field without re-supplying its own.
Receipts stay consequences of the act they name. `handed-to-terminal` is
reported only from a launch command that carried the text or a PTY write that
returned; everything unproven under-claims as `not-delivered`. No fourth arm.
The one inversion is a stalled submission, which the verifier raises after the
write: that is reported as delivered, because a resend would paste the whole
prompt a second time into an agent already working on it.
A prompt the launch command cannot carry is refused at the terminal-create
resolver rather than dropped, since that path returns options and has no PTY
to fall back to.
`delivery: 'draft'` remains `not-delivered` for both surfaces. The host could
paste a terminal draft without submitting it, but it cannot observe that the
composer accepted it, so a receipt claiming delivery would be a guess.
No call site is migrated, nothing is added to the wire, and placement and tab
creation are untouched.
