fix(chat): steer Claude with Ctrl+Enter, guard pending writes, restore a stopped send - #760
Merged

Conversation
…rites Send now on a working Claude pane commits with ctrl+enter, which Claude Code takes as send-now instead of queueing (#737). herdr encodes it as the pane asked, and as a plain CR for a program that asked for nothing. The pending paste and its committing key pass the lease-aware guard to herdr, as the other input paths do since #624: a refusal before the paste leaves the message unsent (held), one before the key leaves it uncertain (#666).
…oser Stopping a chat message right after sending, before Claude Code answers, makes Claude Code take the turn back and put the text in its own input box. The chat kept showing the message as sent with an empty composer, and the next send was refused with input_draft because the box was not empty, while the terminal could simply edit and resend. - server: noteSubmitted keeps the chat's last message per pane; claudeRestoredDraft recognises exactly that text typed back in Claude's box. freeClaudeBox (both send paths) empties that copy with two Esc presses while the agent is not working, re-reads the box and sends; any other draft, bash mode, clipped box or unverified colors still refuse. - GET /api/pane/prompt answers `restored` from the same ANSI read; the composer takes it back without focus, clears only an untouched fill, and the chat does not render that trailing turn. - transcript: Claude writes the re-send as a sibling of the cancelled prompt (same parentUuid, no assistant between); parseClaudeTranscript drops the cancelled one, and turnStarts does not open a turn at the re-send so the incremental page reads both together. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…Esc presses Review of #741: GET /api/pane/prompt took the viewport's ANSI read as both the box and its colors, so a pane scrolled to an older box holding the chat's last message answered it as restored. It now reads the live screen's box and takes the viewport's colors only where viewportShowsLive verifies them, after a cheap check on the read it already made. The two Esc presses that empty Claude's restored copy ask the sender's right before each press and pass it to herdr as a guard, as the paste and key do.

…s in its regression Review of #760: claudeRestoredDraft dropped every space before comparing, so an edit in the terminal that only took out or put in a space still matched and the two Esc presses erased it. Each row's own spaces now count; only a wrap joins rows, with nothing (a split word) or one space or line break between. The browser regression waited fixed times before its negative assertions; it now waits for the next serial prompt or conversation read to have landed.

…y with time to send Review of #760: - claudeRestoredDraft built a regex joining the box's rows with \s?, which backtracks exponentially over a box of blank rows against a near miss (1.3 s at 30 rows here). It now walks the rows over the set of places the sent text can be at, with the same matching rules. - freeClaudeBox could press its two Esc with too little of the send's deadline left, erase Claude's restored copy, then time out without sending. A send with less than RESTORED_CLEAR_RESERVE_MS (2 s) left now clears nothing and answers submit_timeout; both send paths pass their deadline.

Change
Three chat-send fixes for Claude panes reported against v0.4.6.
dispatchPendingTextcommitted every pending message with Enter, and Claude Code queues what Enter commits during a turn. When Send now steers a working Claude pane (!automatic && beforeEnter.working), the committing key is nowctrl+enter, which Claude Code takes as "send now". herdr encodes that key as the pane asked:ESC[27;5;13~under modifyOtherKeys (what Claude Code asks for),ESC[13;5uunder the kitty protocol, and a plain CR for a program that asked for neither (measured on herdr 0.9.3). Automatic next-turn delivery, an idle agent and every other agent keep Enter.authorizePendingas a predicate) that fix(terminal): recheck the sender's right to type right before herdr is written to #624 gave the other input paths, so a sender that detaches, switches roles, disconnects or is revoked while herdr's connect is awaited writes nothing. A guard that refuses the paste leaves the message unsent (held, with the lease's own error code). One that refuses the key after the paste leaves ituncertain(submit_changed), as before.GET /api/pane/prompttook the viewport's ANSI read as both the box and its colors, so a pane scrolled to an older box holding the chat's last message answered it asrestored, filling the composer and hiding the turn (CodeRabbit). The route now checks the read it already makes, then reads the live screen's box and takes the viewport's colors only whereviewportShowsLiveverifies them, as the send paths do.Fixes #737
Fixes #666
Carries #741
Verification
Integration and contract tests ran on an isolated herdr session (
HERDR_TEST_SESSION=herdr-web-ui-test-l2).server/pending-input.contract.test.tsgained three tests: a Claude steer commits with Ctrl+Enter while automatic delivery and Codex keep Enter; and the paste's and the key's herdr connects are held (a wrappedpaneSendText/paneSendKeys) while the sender switches observe→interact. All three failed on main (Claude got\r; the lapsed lease still pasted and still committed) and pass with the fix.restoredroute: a new test in the same file scrolls a pane to an older box holding the chat's message. It answersrestored: null, and the live box at the bottom answers the message.
