* fix(runtime): guard writeToStdout/writeToStderr against post-teardown writes (Ink parity, G20)

Return early if teardownStarted, mirroring Ink ink.tsx:673/702, so a write
after unmount (e.g. a stray useStdout().write or console.log routed through
writeToStdout after teardown) cannot run clear()/write/restore on an
already-torn-down renderer and corrupt the restored terminal state.

Yunfei He 216a7021a0 fix(runtime): restore terminal on signal exit via signal-exit (Ink parity, G18, HIGH) (#47)
* fix(runtime): restore terminal on signal exit via signal-exit (Ink parity, G18)

Previously nothing routed a process signal to teardown(): SIGINT-as-signal,
SIGTERM or SIGHUP killed the process with the cursor hidden, the alternate
screen active and raw mode on, leaving the terminal corrupted.

Mirror Ink (ink.tsx:426): register signal-exit's onExit(teardown,
{alwaysLast:false}) at interactive mount, storing the unsubscribe fn, and
call it first thing in teardown() (ink.tsx:765) so the handler is removed on
unmount()/exit() and can't leak or double-run. teardown() stays idempotent
(teardownStarted guard) so a signal-triggered teardown plus a later unmount
won't double-run, and we don't prevent the process from exiting. Only the
live interactive, non-debug mount registers — render-to-string /
non-interactive paths never touch process signal handlers; registration is
guarded against double-registration.

Uses signal-exit v4 (named onExit export; ships ESM + types, so no
@types/signal-exit needed). PTY test sends SIGINT/SIGTERM/SIGHUP to a mounted
alt-screen app and asserts the captured output ends with show-cursor
(\x1b[?25h) + leave-alt-screen (\x1b[?1049l).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Review follow-ups (3 fixes): register signal-exit whenever interactive
(drop the !debug gate so debug-but-interactive apps, which still enter the
alt-screen/hide the cursor, restore on signal — Ink ink.tsx:426); add
!teardownStarted to the registration so a spent app instance does not
re-register on a same-instance remount (the next unmount() returns early at
the teardownStarted guard before it could unsubscribe — a leak); and make
the PTY test prove the SIGNAL drove teardown (fixture never self-unmounts, so
restore bytes can only come from the signal path) with a debug-mode signal
test, an exit-anchored waitForOutput drain, and a bounded retry for the
async-flush race under saturated runners.

Review follow-ups (2 fixes): synchronous restore flush on signal — the
signal-exit teardown path now writes the restore escapes (show-cursor,
leave-alt-screen, disable-kitty) via fs.writeSync to the stdout fd so they
reach the terminal before signal-exit re-raises the signal (a buffered async
stream.write could be lost on abrupt exit); the normal unmount path keeps async
writes. Removed the config-wide retry:3 from vitest.pty.config.ts (it masked
the whole PTY suite) and scoped a retry:2 to the signal-teardown describe only,
for the residual parent-side node-pty onData read-race under a saturated runner.

Yunfei He 97c61363e5 fix(runtime): linearize screen-reader static + drop empty-SR-frame newline (Ink parity, G17) (#45)
* fix(runtime): linearize screen-reader static output + drop empty-SR-frame newline (Ink parity, G17)

(a) The live static channel flushed <Static> via the 2D grid painter
(paintIsolated) even in screen-reader mode, so bordered static items leaked
box glyphs. paintStaticNode now takes an isScreenReaderEnabled flag and
linearizes fresh static children via renderScreenReaderOutput
(skipStaticElements:false) instead — matching Ink's renderer.ts:24, which
renders node.staticNode through renderNodeToScreenReaderOutput. Non-SR static
is unchanged. render.ts commit() and render-to-string.ts thread the flag.

(b) Interactive SR frames went through renderInteractiveFrame, which appends
"\n" even for empty output, leaking a spurious blank line. Ink's SR path writes
the wrapped output directly with lastOutputToRender = wrappedOutput (no appended
newline), so an empty SR frame emits zero lines. We now suppress the trailing
newline for EMPTY SR output only — matching ink.tsx:573-626 — leaving non-SR
and non-empty SR frames untouched.

Follow-up fixes (two review findings):
- renderToString in SR mode no longer DROPS <Static> output: the SR return
  branch now prepends the captured/linearized static output like the non-SR
  path (Ink's SR renderer returns staticOutput when node.staticNode exists,
  renderer.ts:24-33).
- The SR static linearization now honors the <Static>'s resolved flexDirection
  for separator + child order (read from yoga via getFlexDirection), matching
  screen-reader.ts:73-82 (row/row-reverse → space, *-reverse reverses order);
  the default column case is unchanged.

Yunfei He 2e9c938f5f fix(runtime): guard against two renderers on the same stdout (Ink parity, G14) (#43)
* fix(runtime): guard against two renderers on the same stdout (Ink parity, G14)

Make skipped-mount unmount() a pure no-op: add `skippedMount` flag set in
the instance-reuse guard branch; teardown() and resolveExit() return early
when set, so no write-barrier or stdout touch reaches the owner's stream.
Strengthen test: assert app2.unmount() writes nothing to process.stdout
(catches the pre-fix empty write-barrier) and that app1 still owns the
WeakMap entry after app2.unmount() (third mount on same stdout still warns).

Yunfei He f49a995d03 fix(runtime): clear+reset on terminal-width decrease during resize (Ink parity, G11) (#41)
* fix(runtime): clear+reset on terminal-width decrease during resize (Ink parity, G11)

Track lastTerminalWidth (initialized at mount via resolveSize); onResize clears
writer + resets frameState.lastOutput/lastOutputToRender when the new width is
narrower than the previous width, mirroring the logic in ink.tsx:459-474 that
prevents duplicate overlapping re-renders on terminal narrow. Width increases and
pure height changes are unaffected.

Preserve outputHeight on narrowing (matches Ink ink.tsx:462-466 which leaves
lastOutputHeight intact): zeroing it suppressed the clearTerminal path in
shouldClearTerminalForFrame for overflowing frames (hadPreviousFrame=false).
Adds overflow-path test that was RED with outputHeight=0 and GREEN with the fix.

Yunfei He 33055e429c fix(runtime): throw a descriptive error when raw mode is unsupported (Ink parity, G10) (#40)
* fix(runtime): throw a descriptive error when raw mode is unsupported (Ink parity, G10)

Previously the raw-mode acquire path silently no-opped on a stdin where raw mode
is unsupported (non-TTY / isRawModeSupported false), so using useInput on such a
stdin did nothing with no diagnostic. Ink's handleSetRawMode (App.tsx:315-327)
instead throws immediately when enabling raw mode is unsupported, with two
distinct messages (default process.stdin vs a custom stdin) both pointing at the
isRawModeSupported docs.

StdinController.acquireRawMode now throws that two-message error on
!isRawModeSupported. The unguarded useInput path surfaces it (matching Ink's
use-input.ts, which calls setRawMode(true) ungated). useFocus now guards on
isRawModeSupported before acquiring (matching Ink's use-focus.ts), so focus
degrades to a safe no-op on a non-TTY rather than throwing. releaseRawMode keeps
its no-op guard — Ink only throws when enabling.

* fix(runtime): wrap external stdout/stderr writes in synchronized-update markers (Ink parity, G09)

writeToStdout/writeToStderr now emit bsu/esu around clear+write+restore when
shouldSynchronize, matching the render path and Ink ink.tsx:687-728. The sync
variable was already computed at mount time (render.ts:489); the external-write
functions simply lacked the wrapping. For writeToStderr, BSU/ESU go to stdout
(not stderr) because synchronized-update mode is a stdout capability — exactly
mirroring Ink's ink.tsx:717-728 behaviour.

Yunfei He 34aeb8ec2e fix(runtime): render linear screen-reader output in the live commit path (Ink parity, G03) (#36)
* fix(runtime): render linear screen-reader output in the live commit path (Ink parity, G03)

commit() previously called paint(tuiRoot) (the 2D grid painter) unconditionally
for both the non-interactive and interactive branches, so an app mounted with
isScreenReaderEnabled emitted the visual frame (box-drawing borders, padded
grid) into the live stream instead of flat linearized text. isScreenReaderEnabled
was only consulted to disable commit throttling.

Add a renderFrame(width) helper that branches on isScreenReaderEnabled: when SR
is enabled it linearizes the tree via renderScreenReaderOutput(tuiRoot,
{ skipStaticElements: true }) and wraps it with wrapAnsi(out, width,
{ trim: false, hard: true }), mirroring Ink's onRender SR branch
(ink.tsx:598-603). Both commit branches now call renderFrame() instead of
paint() directly. The non-SR path is byte-for-byte unchanged (renderFrame
returns paint(tuiRoot)). Static output continues to flush through the existing
paintStaticNode path; full SR-static linearization parity is deferred.

render-to-string.ts already used renderScreenReaderOutput and is unaffected.

Yunfei He 3f92240ca9 fix(runtime): coalesce useAnimation ticks within the render-throttle window (Ink parity, G02) (#35)
* fix(runtime): coalesce useAnimation ticks within the render-throttle window (Ink parity, G02)

useAnimation now coalesces scheduler ticks that fall inside the current
render-throttle window and reports delta as the time since the last
RENDERED tick, so velocity-driven motion (position += speed * delta)
advances at correct wall-clock speed even when the commit throttle is
coarser than the animation interval. Previously delta was ~one scheduler
interval per committed tick, under-integrating velocity at render time.

- animation-scheduler: createAnimationScheduler(renderThrottleMs = 0)
  exposes renderThrottleMs on the AnimationScheduler (no-op variant = 0).
- render.ts: derive animationRenderThrottleMs from maxFps using Ink's
  Math.max(1, ceil(1000/maxFps)); 0 on debug/screen-reader/unthrottled
  paths, mirroring the commit-throttle gate.
- useAnimation: tick() skips while now < nextRenderTime; on an allowed
  tick delta = now - lastRenderedTime, then nextRenderTime = now + window.

Also default maxFps to 30 (Ink parity: options.maxFps ?? 30) and derive a
single renderThrottleMs that drives BOTH the commit scheduler and the
animation scheduler, so the coalescing engages on the default non-debug
path (previously it only engaged when maxFps was passed explicitly).

Yunfei He eaf333a5ea fix(runtime): unmount written <Static> items to match Ink (G01) (#34)
* fix(runtime): unmount written <Static> items to match Ink (G01)

Ink's <Static> renders `items.slice(index)` and advances `index` to
`items.length` in a post-commit `useLayoutEffect`, so once an item has been
painted it is removed from the tree and its component unmounts. vue-tui kept
every Static item mounted forever: the component always mapped the full
`props.items`, and write-once was enforced only at flush time via a positional
`writtenCount` slice — the item components never tore down.

Now the <Static> component owns a `cursor` (Ink's `index`) and renders only
`items.slice(cursor)`. The renderer advances the cursor AFTER a commit has
painted the fresh items, via an `onWritten` callback registered on the host
static node — the vue-tui analogue of Ink's post-commit layout effect. This
ordering guarantees items are written before they are sliced out and unmounted,
so no item is ever lost or re-painted.

Write-once bookkeeping moved from a positional `writtenCount` to a
`writtenNodes` Set keyed by host-node identity. A single logical item expands to
several host nodes (the <Text>/<Box> plus empty text-leaf fragment anchors Vue
inserts), so a positional count mis-sliced once the cursor advanced; identity
tracking is anchor-agnostic. The shared `paintStaticNode` helper paints children
not yet in the set, records them, prunes unmounted entries, then fires
`onWritten`; render.ts, render-to-string.ts and flushStatic all use it.

Make the cursor mirror Ink fully so it can DECREASE, not just increase.
`onWritten` now SETS the cursor to items.length (was max-with-current), and a
length watch lowers it on shrink — needed because a shrink that leaves the
already-sliced children empty produces no host mutation, hence no commit/
onWritten to re-sync. Without this, [A,B] (cursor→2) → [A] → [A,C] sliced(2)=[]
and silently dropped C. paintStaticNode now always prunes and calls onWritten
(even on empty commits), painting only when there are fresh children.

Yunfei He 144db33d0b fix(runtime): use terminal-size fallback when stdout reports 0 cols/rows (Ink parity, G12) (#33)
Replace three `stdout.columns ?? 80` / `stdout.rows ?? 24` spots in render.ts with
`resolveSize(stdout).columns/rows`. The `??` guard only falls back on null/undefined,
not on 0 — so non-TTY environments where stdout reports 0 columns would collapse Yoga
layout to width 0. Ink's `getWindowSize` (utils.ts:8-23) uses a truthy guard
(`if (columns && rows)`) and a fallback chain through terminal-size → 80/24 defaults.
`resolveSize()` in useTerminalSize.ts already implements this chain; now exported and
used by the renderer. The non-TTY viewportRows → 24 branch is preserved (Ink-aligned).

Yunfei He f3bb5f268a fix(runtime): cancel pending throttled commit on resize
The resize handler painted synchronously via commit() but left the commit
scheduler's pending trailing throttle timer armed. If an update was sitting
in that timer, it fired a second doCommit() right after the resize paint —
and because shouldClearTerminalForFrame clears whenever the previous frame
overflowed the viewport, the second commit emitted a duplicate clearTerminal.

Cancel the pending trailing commit before the synchronous paint; the paint
already reflects the current tree, so the pending commit is redundant.

Regression test (test-first) in throttle.sequential.test.tsx reproduces the
double-clear (2 clears) and verifies the fix (1 clear). Closes #26 (item 1).

Yunfei He bc61d57a11 fix(runtime): render synchronously on resize, matching Ink
The resize handler routed through scheduler.schedule(), deferring the repaint
through the ~32ms commit throttle. Ink's resized() calls onRender() directly,
and a resize is a discrete viewport change that should repaint immediately —
deferring it can leave stale/overlapping content on screen for a frame.

It also made the clearTerminal-on-overflow behavior depend on wall-clock
timing: the #450 "shrink into overflow" test passed only because the throttled
resize emitted ZERO clears (its trailing timer never fired within the test's
nextTicks) and the single clear came entirely from unmount. The test asserted
the right number for the wrong reason, and the dependency on real elapsed time
made it flaky under CPU contention.

Change the resize handler to commit() directly. Now the resize itself emits the
overflow clear deterministically. Update the test to assert the clear happens
ON the resize (clearsAfterResize - clearsBeforeResize === 1) after a single
nextTick — no longer dependent on throttle timing.

Yunfei He 81b068eda1 fix: waitUntilRenderFlush waits for scheduled-but-not-yet-pending commits
Codex review found waitUntilRenderFlush gated the scheduler flush on
hasPending() alone, missing the window after schedule() queues a commit
but before the post-flush callback sets hasPendingFlag — letting the
promise resolve before the pending render flushed. Now delegates to
flush() unconditionally; flush() already short-circuits when nothing is
scheduled or pending, so this only adds the missing wait.

Yunfei He 7d03a110e1 fix: address /simplify review — frame-writer dedup desync, scheduler edge cases
Correctness fixes found by max-effort review of the branch diff:

- frame-writer.sync() now updates lastFrame alongside log-update's
  previousOutput. Previously the two dedup layers desynced after a sync()
  (the clearTerminal path), silently dropping a legitimately-changed frame
  and emitting an empty BSU/ESU pair. Adds a regression test.
- scheduler: the queuePostFlushCb callback now bails if scheduled was reset
  by cancel(), so a stale callback can't commit on a torn-down tree or
  re-arm an uncancellable trailing timer.
- scheduler.flush() now collects multiple concurrent waiters instead of
  overwriting a single resolver — fixes a hang when two waitUntilRenderFlush()
  calls await the same pending commit.
- render teardown nulls mountedClear so a post-unmount app.clear() can't
  write to a torn-down stream.
- test-streams getContentWrites imports bsu/esu instead of hardcoding the
  escape literals.

is not yet supported.

multiselectable listbox.

Also fix component prop bug: Vue normalizes kebab-case prop names to camelCase
at runtime, so props["aria-label"] was always undefined. Switch Box/Text prop
declarations and access to camelCase (ariaLabel, ariaHidden, ariaRole, ariaState).

Add isScreenReaderEnabled option to renderToString() so tests can exercise

Yunfei He 5b1035792c fix: add final unmount render to trigger shouldClearOnUnmount
Ink does an explicit onRender() with isUnmounting=true before unmount
(ink.tsx:755-761), which triggers clearTerminal for fullscreen apps.
vue-tui's teardown() was nulling scheduledCommit before unmount, making
shouldClearOnUnmount dead code. Now calls commit() synchronously before
disabling the scheduler, matching Ink's unmount render behavior.

Restores 2 erase PTY tests that were incorrectly attributed to a
React vs Vue rendering difference.

Yunfei He d8dde1438d fix: fix PTY test failures — stdin double-processing, raw mode exit hang, fixture JSX
Three runtime bugs and fixture issues fixed:

1. stdin registered both "readable" and "data" handlers, causing double input
   processing in real PTY. Now only uses "data" handler (works for both real
   TTY and fake PassThrough streams).

2. dispose() didn't call stdin.unref() after restoring raw mode, keeping the
   event loop alive and causing raw mode exit tests to hang.

3. PTY fixtures used JSX syntax which tsx compiles without vue-jsx plugin,
   producing non-function slot values. Converted to h() with function slots.

Also: term.ts now passes rows arg to node-pty for viewport-dependent tests,
and exit-double-raw-mode fixture uses __READY__ protocol.

Yunfei He dd4c5aa3e1 fix: replace node-pty with child_process.spawn + force-tty preload
node-pty's posix_spawnp is blocked in sandboxed environments.
child_process.spawn works everywhere. force-tty.cjs patches
stdout.isTTY so fixtures behave as if running in a real terminal.

Also fix setRawMode this-binding bug (acquireRawMode on undefined).

72/82 PTY tests now pass. Remaining 10 need timing/assertion fixes.

Yunfei He 05c4dd5076 feat: add beforeExit natural unmount + stdout write barrier
Register process.once('beforeExit') in waitUntilExit() so TUI apps
that finish naturally (no explicit exit/unmount) clean up before the
event loop drains. Add stdout write barrier in resolveExit() to ensure
all output is flushed before settling the exit promise.

Update testing render helper to await the additional async tick
introduced by the write barrier so early-error detection still works.

Yunfei He 3ee01dc278 feat: add patchConsole, waitUntilRenderFlush, onRender, and maxFps
Add four behavioral surfaces to the runtime:

- patchConsole (default: true): intercepts console.* methods to route
  output through writeToStdout/writeToStderr, preventing frame corruption.
  Disabled in debug mode. Restored before Vue cleanup on teardown.
- waitUntilRenderFlush(): flushes pending throttled renders and waits
  for the stdout write barrier, exposed on TuiApp and testing RenderResult.
- onRender callback: fires after each commit with { renderTime } in ms.
- maxFps option: overrides the scheduler's default 32ms throttle interval
  with 1000/maxFps. The scheduler now accepts a throttleMs option and
  exposes hasPending() for flush coordination.

Yunfei He 1106be867b feat: add error boundary with onErrorCaptured to catch descendant errors
Wrap user root component in an InternalErrorBoundary that catches all
descendant errors (setup, render, lifecycle) via onErrorCaptured and
routes them through exit(error). This prevents yoga WASM state corruption
that occurred when errors propagated uncaught during Vue's render phase.

- Add ErrorOverview component for rendering error frames
- Replace try-catch around mount with onErrorCaptured boundary
- Update testing render() to detect early exit errors
- Convert 3 todo tests to active tests (nested setup, unhandledRejection, post-mount)

Write ESC[?25l to stdout after mount and ESC[?25h during teardown,
matching Ink's cursor management. Only active in production mode
(debug: false) to avoid interfering with test streams.

Yunfei He 8565f41827 feat: add time-based render throttle (~30fps) matching Ink
Add leading+trailing throttle to the commit scheduler in production mode.
In debug/test mode (immediate: true), commits fire without delay to
preserve test determinism. Adjusted the non-debug static test to account
for the throttle timer.

Yunfei He bcfdaddec7 feat: exit() accepts result value, waitUntilExit resolves with it
Change exit(error?: Error) to exit(errorOrResult?: unknown). When an
Error is passed, waitUntilExit rejects; otherwise it resolves with the
value. This matches Ink's behavior where exit("hello") resolves the
promise with "hello".

Yunfei He 5b399e0844 feat(runtime): enable raw mode by default on mount
TUI apps should suppress terminal echo to prevent keystroke pollution
in the rendered UI. Raw mode is now on by default (matching Bubbletea,
Textual, Ratatui), with exitOnCtrlC also defaulting to true.

Pass rawMode: false to mount() for pure-output CLI tools that don't
need input suppression.

Yunfei He b834a87529 fix(runtime): clear dynamic frame before flushing static content
flushStatic() writes directly to stdout, but log-update tracks cursor
position for in-place re-rendering. Without clearing log-update first,
the static content gets overwritten when the dynamic frame re-renders.

Adds a regression test that verifies the clear sequence appears before
static content in non-debug mode.
