Closes #753

Change

The composer and queued-message textareas set spellCheck={false}, autoCapitalize="off" and autoCorrect="off", so on a phone (iOS especially) the chat box gets no autocorrect, no QuickType suggestions and no sentence capitals. That suits commands and paths, but most of what gets typed to an agent is prose, which is slow to type without them.

This adds Settings → Chat → Composer → Autocorrect, following the proposal in #753: off by default (today's behaviour), saved per device (SETTING_SCOPE "device", since it is about this device's keyboard). When on, both textareas use spellCheck, autoCapitalize="sentences" and autoCorrect="on". The terminal input line keeps its current attributes.

  • src/lib/compose.ts: new composerKeyboard(autocorrect) returns the three attributes; Composer.tsx and the queued-message textarea in PaneTerminal.tsx spread it.
  • src/lib/settings.ts: chatAutocorrect (default false, sanitized as a boolean, device scope, included in the telemetry snapshot); shared/telemetry.ts gets its schema entry.
  • src/components/SettingsDialog.tsx: a Toggle row after Enter sends, with ko/ja/zh/tr strings.
  • DESIGN.md, docs/guide.md, CHANGELOG.md (Unreleased → Added).

Validation

  • bun run generate:types --check, bun run typecheck and bun run build pass.
  • bun run test:unit: 2979 pass, 1 fail. The failure (voice transcribe > streams deltas and the done text from a split SSE answer) also fails on unmodified main in my environment (it did in feat(paste): configurable attachment directory with HERDR_WEB_PASTE_DIR #357 too), so it is unrelated. New unit tests: composerKeyboard in compose.test.ts, and default/scope/sanitize of chatAutocorrect in settings.test.ts; api.test.ts and telemetry/worker.test.ts updated for the new telemetry field.
  • scripts/ui-regression.ts gets a new block that checks the message box's spellcheck/autocapitalize/autocorrect attributes are false/off/off by default, true/sentences/on after turning the toggle on, and back off after turning it off. The full script passes on the isolated herdr-web-ui-test session (Chromium 1243, linux arm64). One earlier run failed on the palette assertion "a scroll under a resting pointer leaves the arrow's selection alone", unrelated to this change, and passed on rerun.
  • Screenshot from the demo build (390px, touch), with Autocorrect turned on:

Settings → Chat → Autocorrect (off by default, per device) switches the composer and queued-message textareas from spellcheck=false/autocapitalize=off/autocorrect=off to spellcheck, sentence capitals and autocorrect, so phone keyboards correct and suggest in chat. The terminal input line is unchanged.

Cover the queued-message textarea

The regression check reads only composer, so it verifies the main Composer textarea. The existing queue checks verify message delivery and persistence, but not keyboard attributes. A queued textarea that ignores chatAutocorrect can therefore pass all current checks while the main textarea still works.

…aging keys repeat (#965)

## Problem

Two small touch-input papercuts in the terminal lens:

1. **Autocorrect in the input line.** On iPhone the terminal input line
(input-line mode) leaves iOS Auto-Correction and spell-check on. Typing
a command with a non-dictionary token (a flag, path or branch name) and
pressing Space can let the keyboard swap it for a dictionary word, and
Send sends the rewritten command. Every other command or text field
(composer, queue editor, key-bar settings, secret input, Portal panel)
already turns autocorrect off.
2. **Held key-bar Backspace fires once.** Holding the key-bar ⌫ deletes
one character; clearing a line takes one tap per character. The
hold-to-repeat added in #758 covers only the four arrows. Same for Del,
Home, End, PgUp and PgDn.

## Cause

1. `src/components/TerminalInput.tsx`: the textarea sets only
`autoCapitalize="off"`; no `autoCorrect="off"`, no `spellCheck={false}`.
Its doc comment even listed autocorrect as a rewrite the line exists to
absorb.
2. `src/lib/keyRepeat.ts`: `isRepeatableKeyBarItem` returns true only
for `ArrowUp/Down/Left/Right`. `KeyBar` wires press-and-hold only for
repeatable items, so every other key is a plain click. (#718 left
"should Backspace, Delete, PageUp, PageDown repeat too?" as an open
question; #758 shipped arrows only.)

## Fix

Two commits:

1. `TerminalInput` textarea gets `autoCorrect="off"` and
`spellCheck={false}`, matching `Composer.tsx` and the queue editor. The
doc comment now says autocorrect stays off and why.
2. `isRepeatableKeyBarItem` uses a set: the arrows plus Backspace,
Delete, Home, End, PageUp, PageDown, with or without saved modifiers
(like the arrows). Escape, Tab, BackTab, Enter, Insert, ^C/^D/^Z,
F-keys, printable keys and modifier buttons stay single-shot: a repeated
Tab or ^C would act many times on what one press meant. Delay and rate
are unchanged (400 ms / 50 ms).

## Tests

- `src/lib/keyRepeat.test.ts`: the positive case now covers the six
editing/paging keys (bare and with saved modifiers); the negative case
keeps Escape, Tab, BackTab, Enter, Insert, ctrl-c, ctrl-d, F1, printable
keys and modifiers. Fails without the fix (1 fail), passes with it.
- `scripts/key-bar-hold-repeat-regression.ts`: new step 5b holds the
key-bar ⌫ and checks it repeats (the DEL byte on the input path, 11
sends in the run) and sends nothing after release. Without the fix the
step fails ("got 1"). `bun run check run bun
scripts/key-bar-hold-repeat-regression.ts`: all steps pass.
- `scripts/terminal-input-regression.ts` (run inside
`ui-regression.ts`): asserts the input line has `autocorrect="off"`,
`spellcheck="false"`, `autocapitalize="off"`. `bun run check run --build
bun scripts/ui-regression.ts`: pass (exit 0), including "PASS terminal
input".
- `bun run typecheck`: pass. `bun run test:unit`: 3069 pass, 0 fail
(including the #949 conventions guard; the new post-release wait carries
a `// fixed wait:` note).
- Native iOS autocorrect was not reproduced on a device; the fix relies
on WebKit honouring `autocorrect="off"`, as the composer already does.

## Notes

- Refs #862 (held backspace does not repeat). This fixes the key-bar ⌫
case. The issue does not say whether the reporter held the key-bar key
or the system keyboard's backspace; the soft keyboard's own repeat goes
through xterm's textarea, not this code, so I did not use "Closes".
- `DEFAULT_KEY_BAR_ITEMS` is unchanged: ⌫ is still opt-in through
key-bar customization. Neither #862 nor the docs ask for it in the
default bar, and changing defaults touches settings migration and
telemetry customization flags.
- #935 (opt-in composer autocorrect, open) touches `Composer.tsx` /
`PaneTerminal.tsx` / `compose.ts` only; no file overlap. Its body says
"the terminal input line keeps its current attributes"; after this PR
those attributes are off, matching the composer default. I suggest its
toggle should not cover the terminal line, since shell tokens are the
worst case for autocorrect.
- #943 and #946 (open) touch `KeyBar.tsx` but not the repeat logic or
`keyRepeat.ts`; this PR does not edit `KeyBar.tsx`.
- Changelog: one fragment,
`changelog.d/terminal-input-autocorrect-and-key-repeat.md` (two Fixed
entries).

## Merge-session review

Fixed (3468ec3):
- `docs/terminal-input.md` still said only the arrows repeat when held.
It now lists the arrows, ⌫, Del, Home, End, PgUp and PgDn (saved
combinations of these repeat too) and says Esc, Tab, Enter, ^C, F-keys
and modifier buttons send once.
- `docs/development.md` now describes
`key-bar-hold-repeat-regression.ts` as covering holds of arrows and
editing keys.

Docs only, so there is no new regression test;
`src/lib/keyRepeat.test.ts` and browser step 5b already pin the
behavior. `bun run check fast` passes. The changelog fragment was
already accurate.

Deferred: none.

…bar (#964)

## Problem

A phone shows a pane in the terminal lens while a desktop tab of the
same pane takes the pty back to its own size (a click or key in the
desktop terminal, or the desktop window coming back to the front). The
phone's xterm stays at phone width while herdr streams rows drawn for
the desktop's width, so lines wrap in the wrong place and agent TUIs
look scrambled. Typing in the input line, Send, Enter and key-bar taps
did not fix it. Only a touch on the grid itself, a focus change or a
reload did.

## Cause

In the terminal lens, an interact client stores `pane-geometry` in
`sharedGridRef` and then ignores it, because it drives the grid itself.
The only thing that took the size back while the window kept its focus
was `reclaim`, and that runs only for a pointerdown or keydown whose
target is inside `term.element`. The phone's usual input paths are all
outside that element:
- `sendTerminalLine` submits from the `TerminalInput` textarea.
- `pressEnter` sends `\r`/keys from the same line.
- `pressKey` calls `term.input()` from the key bar, with no DOM event on
the grid.

## Fix

- The size check moves out of `reclaim` into `reassertIfStale()`. When
the shared grid differs from this grid, the tab is in use and has not
released its pane, it calls `refit()` (force resize).
- `reclaim` keeps its event filters (target inside the grid, no
IME/repeat key, primary button) and then calls the helper.
- `sendTerminalLine`, `pressEnter` and `pressKey` call it before they
send, so the resize frame goes out before the input on the same socket.
- `TerminalInput` gets an optional `onFocus`, wired to the same helper.
Tapping into the input line counts as the user being back, the same way
a tap on the grid does.
- No resize was added for the keyboard opening or closing. That is a
separate policy question (viewport-resize-2).

## Tests

- `scripts/chat-size-regression.ts`
`checkFocusedWindowReclaimsTerminalSize` (already in
`ui-contexts-checks.ts`, so it runs in the browser lane) now continues
with two clients after its existing steps. A desktop at 1280x800 and a
phone at 390x844 in line mode take turns:
  - a tap into the input line;
  - a line sent with Enter;
  - a key-bar Ctrl+C;
  - Enter on the empty line.

Each phone step comes after a desktop key has taken the pty back. Each
step asserts that the phone's own-size `resize` frame goes out before
its `submit`/`input` frame, and that the pane's shell (`stty size`)
reports the phone's size again.
- `CHAT_SIZE_CASE=reclaim bun scripts/chat-size-regression.ts` now runs
that check on its own.
- Without the `src/` change the new step fails ("a tap into the input
line takes the pane back to the phone's grid"). With it, `bun run check
run --build bun scripts/chat-size-regression.ts` (with
`CHAT_SIZE_CASE=reclaim`) passes.
- `bun run typecheck` and `bun run test:unit` (3069 pass, 0 fail) pass.
- `check full` / `concurrent` was not run.

## Notes

- Source: a mobile-terminal stability audit, finding viewport-resize-1.
Related: #472 (the chat-lens version) and #712 (an attach holds the
pane's size). Neither covers this path.
- No open PR touches `reclaim`, `sharedGridRef`, `sendTerminalLine`,
`pressEnter` or `pressKey`. #951, #950, #946, #945, #936, #935, #932,
#910, #894, #859 and #822 edit other parts of `PaneTerminal.tsx`. #936
also edits `TerminalInput.tsx` (dictation), so a small textual conflict
is possible there.
- The size tug-of-war between two devices that both type into the same
pane remains by design: whichever device the user is typing on takes the
pty. A "sized by another device" notice and passive adoption of the
foreign grid were left out.

Thank you for this, and for the careful tests. Closing in favor of a smaller change without a new setting: the app is reducing its settings (#1099, #1104), and this one would also widen the telemetry schema. The chat message box will get autocorrect, suggestions and sentence capitals by default, while the terminal input line keeps them off (#753).

## Change

Closes #753. Replaces #935 without adding a setting.

The chat message box (`Composer.tsx`) and a queued message's textarea
(`PaneTerminal.tsx`) set `spellCheck={false}`, `autoCapitalize="off"`
and `autoCorrect="off"`. On a phone (iOS especially) the box therefore
had no autocorrect, no QuickType suggestions and no sentence capitals,
although most of what is typed to an agent is prose.

Both now use `spellCheck`, `autoCapitalize="sentences"` and
`autoCorrect="on"`. Fields for code-like input keep them off: the
terminal input line (`TerminalInput.tsx`, still asserted by
`scripts/terminal-input-regression.ts`), secret input, and the path,
branch and relay fields.

This matches other mobile agent clients: t3code's native iOS composer
defaults to `autoCorrect`/`spellCheck` true
(`apps/mobile/src/native/T3ComposerEditor.ios.tsx`), and Paseo's
composer passes no keyboard props, so it takes React Native's defaults.
Both turn them off only on code-like fields.

Trade-off: a phone keyboard may now replace an unknown word (a flag, a
branch or function name) in the chat box before Send, and desktop
browsers underline unknown words.

## Validation

- `bun run typecheck`: passes.
- `HERDR_TEST_MODE=unit bun test ./scripts/changelog-fold.test.ts
./src/conventions.test.ts ./scripts/conventions.test.ts`: 27 pass, 0
fail.
- Not checked on a real phone keyboard.
