* fix(native-chat): mirror multi-line launch drafts into the chat composer
seedNativeChatLaunchDraftForAgentTab rejected any text containing a newline,
so every Linear launch ("Linked Linear issue: X\n<url>") and any GitHub launch
with a typed note was invisible in chat. The rejection existed because the send
path pre-cleared the TUI with a single Ctrl+U, which cannot clear a buffer with
embedded newlines.
Orca injects the draft itself, so when the composer still holds exactly what was
injected the buffer already IS the message: the send becomes the submit key
alone — no clear, no paste, nothing that can concatenate, and multi-line submits
as one turn for free. Only the edited case needs real buffer replacement, and
that now clears every line and verifies against the agent's rendered input line
instead of firing blind.
Measured on real PTYs against Claude Code and codex (both agree exactly):
clearing N logical lines costs 2N-1 Ctrl+U. See src/shared/agent-tui-input-clear.ts
for the law, the sequences that do NOT work, and why an upper bound is safe.
* fix(native-chat): send the mobile clear burst as its own write
Live QA caught the bundled form failing: a multi-line burst prefixed onto the
body in the SAME terminal.send reached the agent as LITERAL Ctrl+U characters,
so the parked draft survived and the message arrived as
draft + 21x \x15 + body. Sending the burst as its own non-submitting write —
the shape the image paste has always used — clears as intended.
The body write's own single-Ctrl+U prefix is dropped once that dedicated clear
ran, for the same reason: a Ctrl+U immediately followed by body text in one
write lands as a literal control character and headed the received message.
Re-verified live end to end: received prompt is exactly the draft, one turn,
zero control characters.
* test(native-chat): invert the multi-line Linear launch-draft mirror expectation
The Linear work-item launch seeds `Linked Linear issue: ENG-42\n<url>\n`.
This test pinned the pre-relaxation rule (multi-line drafts withheld), which
the send path no longer needs now that it submits the TUI buffer in place or
clears every line first — so it asserted the exact behavior the fix removes.
Assert the seeded payload instead of absence, so the test fails if the mirror
regresses to single-line-only.
