* Revert "fix(terminal): avoid flash while restoring parked terminals (#10871)"
This reverts commit 5a6a9e0b28.
Reverted for terminal rendering regressions (flashing, lost content).
Conflict resolution preserves the forwardRef signature from #10433 and
drops the parked-presentation gating #11016 fed with its effective set.

* Revert "fix(terminal): limit pre-paint WebGL resume to macOS (#10794)" and "fix(terminal): stop switch bold flash and Windows lag (#10692)"
This reverts commits 4681edb520 and
8f5a45401f.
#10794 was itself a partial revert of #10692, so both are reverted
together: the Windows retained-WebGL LRU and the macOS pre-paint
(layout-phase) visibility transition that survived it. Terminal
visibility resume returns to passive disposal and recreation on every
platform, and the WebGL context ceiling returns to a flat 128.

* fix(terminal): release an abandoned synchronized-output frame on reveal
Alt-screen agent TUIs (OpenCode/OpenTUI, Codex, grok) bracket every repaint
in `?2026h … ?2026l`. Hiding a pane mid-bracket — which a worktree switch or
cold-park lands on routinely, since these brackets are written many times a
second — leaves xterm's `decPrivateModes.synchronizedOutput` latched.
RenderService.refreshRows checks that latch *before* rendering, so while it
holds, every repaint Orca owns is a no-op: the forced render-pause repaint,
the plain `refresh()` fallback, and the shared glyph-atlas rebuild all render
zero rows while the xterm buffer is perfectly correct. Release the latch at
the two reveal repaint entry points so those repaints actually paint.
Also adds an OpenCode-shaped alt-screen e2e fixture and spec. The existing
inline-TUI convergence spec covers the normal-buffer shape (live block glued
to the bottom, history scrolling into scrollback); this covers the
full-screen alternate-buffer shape, where nothing scrolls and so no row ever
self-heals through the scroll path.
Scope note: xterm arms a 1s watchdog that clears this latch on its own, so
this closes a bounded window rather than the whole STA-2694 report. The e2e
spec passes with and without the production change for that reason; the unit
tests are what pin the behavior. Refs STA-2694.
* fix(terminal): clear the render model on the plain-refocus repaint path
`schedulePaneRevealPresent` — the atlas-preserving path a plain window
refocus takes — only called `terminal.refresh()`. xterm's renderers are
diff-based: `_updateModel` early-continues on any cell whose code/fg/bg/ext
still match the cached model, so a refresh repaints nothing for a pane whose
buffer never changed. When an occluded window loses its canvas contents while
that model stays populated, the refresh skips exactly the cells that went
stale and the pane keeps compositing pre-hide pixels — until a window resize
reallocates the model, which is the repair users find by hand.
Clear the model first (`RenderService.clear()` → renderer `clear()` →
`_clearModel(true)`) so the refresh becomes a guaranteed full repaint. That
drops cached cells and glyph vertices but NOT the texture atlas, which is
shared by every same-config terminal and whose mid-stream wipe re-arms xterm's
page-merge garble race (xterm.js #4480) — the reason this path is
atlas-preserving in the first place.
Also covers the DOM-renderer fallback in `resetWebglTextureAtlas`:
`clearTextureAtlas()` is what invalidated the model on the WebGL path, so a
pane without an addon had nothing invalidate it and hit the same skip.
Scope note: the e2e spec guards buffer/geometry convergence across the
hide/reveal boundaries and adds idle-agent and headful desktop-hide cases, but
it cannot observe a stale canvas — both oracles built for that (canvas-vs-buffer
ink sampling, screenshot-vs-forced-repaint) were proven blind by injecting the
defect, and the spec header documents why. The unit tests pin the ordering and
the atlas-preservation invariant. Refs STA-2694.

* docs(terminal): hand off the STA-2694 reveal-artifact investigation
Records both fixed defects with their xterm mechanisms, the reveal/wake call
graph, why every e2e oracle for a stale canvas was proven blind, how to arm the
in-app render-desync sentinel on real hardware, and the one unverified lead
(dimension staleness) that would explain why a window resize specifically is
the repair users find. Refs STA-2694.

* Revert "fix(terminal): clear the render model on the plain-refocus repaint path"
This reverts commit 0f7ec4458d37010338f16e70ff06957cb335e074.
* test(terminal): add a draw-command oracle for reveal repaints, and correct the STA-2694 scope
Every pixel oracle tried for STA-2694 was blind: `drawImage` on a
non-preserveDrawingBuffer WebGL canvas returns a re-rendered copy, and
Playwright's screenshot drives a fresh compositor frame that heals a stale paint
before capture. Reading pixels is self-defeating here — the read triggers the
repaint that hides the bug.
Count the WebGL draw commands instead, by wrapping GlyphRenderer.updateCell and
gl.drawElementsInstanced on the live pane. A draw command cannot be healed after
the fact, so "did the reveal actually repaint?" becomes directly observable.
Teeth-verified: removing releaseAbandonedSynchronizedOutput from
schedulePaneRevealPresent fails the stranded-latch test.
Two findings, both of which change previously-committed claims:
1. The 1s watchdog does NOT bound the synchronized-output defect. It is armed
only inside `bufferRows`, and `refreshRows` returns at its `_isPaused` check
first — so while a pane is occluded nothing reaches `bufferRows` and no timer
is ever pending. A pane hidden mid-`?2026h` holds the latch with no watchdog
behind it, indefinitely. ed1eaf55f1's "closes a bounded window" scope note was
wrong; this is the unbounded garble the report describes, and the fix closes
it. Corrected in the module doc comment.
2. It refutes the diff-based-staleness hypothesis behind 0f7ec4458d (reverted in
8d5eacecb4). `_updateModel` does early-continue per unchanged cell, but
`GlyphRenderer.render` then copies vertices for EVERY row up to
`lineLengths[y]` and issues ONE full-viewport draw — measured identical
instance counts (562) for a diff-skipped and a model-cleared refresh, with
updateCell at 0 vs 561. The DOM renderer likewise replaceChildren()s every
row unconditionally. Clearing the model could not change what reached the
screen, and `_clearModel(true)` zeroes every glyph vertex while
`RenderService.clear()` fires no repaint of its own — so it opened a
blank-viewport window (also asserted here) for no benefit.
Also keeps the idle-agent and headful desktop-hide cases from the reverted
commit, since those were independent of the refuted production change, and
rewrites the alt-screen spec header to point paint questions at this oracle.

* docs(terminal): rewrite the STA-2694 handoff after the refutation
Records that the garble window is unbounded (the 1s watchdog never arms for an
occluded pane), that the diff-based-staleness hypothesis was refuted by
measurement and reverted, why pixel oracles are structurally blind here, and the
two leads now closed by measurement (dimension staleness, lazy atlas bindings).
Refs STA-2694.

* test(terminal): capture visual proof of the STA-2694 stale paint
The earlier screenshot oracles were blind because they compared a revealed pane
against a repaired one and both ran the same repaint code. Capturing the defect
directly works instead, because the mechanism is self-preserving: while
synchronizedOutput is latched, refreshRows returns before reaching the renderer,
so a compositor frame just re-composites the existing canvas texture and the
stale pixels survive the screenshot rather than being healed by it.
Latch a frame, write a full new frame the pane cannot paint, and capture. The
screenshot comes back byte-identical to the pre-hide one while the buffer holds
the new frame — the buffer/screen divergence users report — and differs after
the reveal repaint runs. Asserts both halves, so it fails if either the defect
stops reproducing or the fix stops repairing it.

* test(terminal): note where the xterm gate-order double is pinned for real
The unit double encodes RenderService's paused-then-latch gate order, which can
drift on an xterm upgrade. Point at the e2e oracle that pins the same order
against the real renderer, so a future upgrade has a trail to the authoritative
check. Refs STA-2694.

* test(terminal): add a perf budget for the synchronized-output release
releaseAbandonedSynchronizedOutput runs inside resetWebglTextureAtlas, which a
streaming alt-screen TUI can reach through the terminal-output atlas recovery
path — not only on reveal. Measure rather than assert that this costs nothing.
Steady state (a TUI that closes every frame it opens): 200 bracketed frames
produce zero releases, zero extra draw calls, and an unmeasurable early-out
cost. Worst case (every reveal finds a latched frame): 50 latched atlas resets
at 0.08ms each. Both are asserted with headroom, so the guard catches a future
change that makes this scan the buffer per pane rather than flaking on machine
speed. Refs STA-2694.
Co-authored-by: Orca <help@stably.ai>
* test(terminal): address review — drive real code paths, close vacuity gaps
CodeRabbit caught a genuine tautology in the perf budget: it timed a
hand-copied mirror of the early-out rather than the shipped function, so the
assertion would have held even if the real code grew a buffer scan. Driving
resetWebglTextureAtlases instead moved the measured cost from ~0 to ~0.03ms per
call, which is the honest number for the whole recovery; bound re-set to 0.4ms
(10x measured).
Other review fixes:
- Assert the draw counts both perf tests were measuring and logging but never
checking, so the 'no extra draws' titles now mean something.
- Fail fast when decPrivateModes is unavailable; previously the latched test
would pass without ever exercising the fix.
- Re-check the latch right after the worktree switch in the mid-frame test: the
pane is visible until then, so the 1s watchdog can arm and clear it before the
hide, making the run vacuous.
- Count scheduleRevealPresent invocations instead of returning a literal true,
so a missing test hook no longer masquerades as a production failure.
- Assert the latch clears on every reveal iteration, not just the last.
- Make the fixture heartbeat write atomic (tmp + rename); writeFileSync
truncates first, so a reader could see '' and read it as frame 0.
- Relabel assertRevealPixelsNeedNoRepair as the weak secondary check it is; it
contradicted the file header by calling itself 'the decisive paint assertion'.

* Add native chat skill and command picker with host-aware discovery
Adds a unified, keyboard-first skill and command picker to native chat that:
- Uses agent-native invocation syntax (slash for Claude/OpenClaude/Grok, dollar for Codex)
- Discovers skills only on the pane's execution host (local, WSL, SSH-unavailable, or runtime)
- Groups or separates commands and skills per agent configuration
- Deduplicates by canonical path but preserves visibility through all contributing roots
- Handles IME composition, loading states, and errors without claiming PTY-level control

* fix(mobile-pairing): route Use row through translate() with i18next interpolation
* refactor(mobile-pairing): extract NetworkInterfaceCombobox shared by MobileHero and Settings section
The Popover + Command + manual-entry UX lived only in the Settings →
Mobile → Network Interface section. The mobile pairing screen
("Step 2 of 2 — Pair this computer") had its own copy of the same
Select-based dropdown that did not support manual address entry. A
user trying to pair with a Tailscale MagicDNS hostname from the
pairing screen could not enter it.
Extract the typeable combobox into a shared
`NetworkInterfaceCombobox` component. Both surfaces now render the
same Popover + Command with manual address entry, the `Use "..."`
row, the inline validation error, and the `(custom)` trigger label.
Settings keeps its own Generate QR button, Refresh + Tooltip, and
Tailnet accordion around the combobox. The pairing screen keeps its
existing layout (label + combobox + refresh icon).
Net deletion: ~160 lines. Net behavior gain: manual address entry is
now reachable from both surfaces, not only Settings.
* style(ui): give CommandInput a visible background so the search box is not lost
The Popover content above the CommandList renders the cmdk CommandInput
with only a thin bottom border. Against a white popover background it
visually disappears, especially in the mobile pairing screen where the
popover sits inside a dark phone mockup. Add a subtle `bg-muted/30` +
`py-1` so the input row is unambiguous, without changing the input's
shape or behavior.
* fix(mobile-pairing): drop cmdk CommandItem, use plain buttons inside Popover
In `pnpm dev` HMR cycle the cmdk CommandItem `onSelect` dispatch was
unreliable — clicking the item fired the synthetic event but the parent
React state never received it, so the trigger label never updated after
the user picked a manual address or a refreshed interface.
Replace the `Command` + `CommandItem` primitives inside
NetworkInterfaceCombobox with a native `<input>` + `<button>` list
wrapped by Radix `Popover`. The list now responds to the user's first
click without any intermediate effect that could be skipped in dev mode.
The combobox keeps the same props contract, the same placeholder, the
same inline validation, and the same `Use "<address>"` row at the
bottom of the list.
Update MobileNetworkInterfaceSection.test.tsx selectors from
`role=option` (cmdk's) to `role=button` so the integration test still
asserts the right element. All 479 feature tests still pass.
* debug(mobile-pairing): log handleSelect* invocations to confirm click path
* fix(mobile-pairing): commit on pointerdown to beat Radix Popover close race
In dev mode Radix Popover's close-on-pointerdown handler occasionally
fires before React's synthetic click dispatch reaches the option button,
so the parent's selectedAddress never updates after the user picks a
manual address. Bind the commit handler to pointerdown (synchronous,
before any pointer-up / click synthesis) and call event.preventDefault()
to avoid text-selection side effects. Keep onClick as a fallback so
keyboard / touch / programmatic-dispatch paths still work.
* fix(mobile-pairing): keep manually-typed addresses across network refresh
`selectRefreshedNetworkAddress` used to fall back to the first OS
interface whenever `currentAddress` wasn't in the OS-enumerated
list — so a user who typed a Tailscale MagicDNS name saw their
selection snap back to LAN every time `loadNetworkInterfaces`
returned. Treat manual entries as sticky by passing an
`isManual` flag from the caller; `selectRefreshedNetworkAddress`
now keeps the address when the caller says the user typed it.
`MobilePage` tracks `addressIsManual` alongside
`selectedAddress`: `handleAddressChange` flips it on when the
picked address is not in the OS list, and `loadNetworkInterfaces`
passes it through so refresh keeps the choice.
* chore(mobile-pairing): remove debug logs and sync new-combobox-listbox i18n key
* fix(mobile-pairing): address CodeRabbit review on manual-address lifecycle
Three real bugs from review, plus a regression test:
1. NetworkInterfaceCombobox in MobileHero was disabled when
`networkInterfaces.length === 0`, which locked users out of the
only path to type a manual address during a transient empty
discovery. Pass `disabled={false}` and let the combobox's
own empty-state copy explain the situation.
2. `selectRefreshedNetworkAddress` returned `undefined` whenever
`interfaces.length === 0`, even if the user had a manual
address and `currentAddressIsManual` was true. Keep the manual
address so a recovering discovery doesn't clobber it.
3. `loadNetworkInterfaces` could rewrite `selectedAddress` (e.g.
when a refresh swaps to a freshly-discovered tailnet) but never
updated `addressIsManual`, so the next refresh could revert
the user back to LAN. Re-derive `addressIsManual` from the
new address after every refresh.
Adds a regression test in
`mobile-network-interface-selection.test.ts` exercising the
empty-refresh + manual path.
* style(mobile-pairing): trim disabled-false comment to two lines
* refactor(mobile-pairing): replace typeable combobox with select + custom-address dialog
The Settings/MobileHero network selector used a Popover+search-input hybrid
that looked uneven and hid its validation error behind the open popover.
Replace it with a plain Select of discovered interfaces plus an
'Add custom address…' footer row that opens a small dialog for entering a
Tailscale hostname or static IP. Drops the 'MagicDNS' jargon for plainer
copy, keeps the '(custom)' trigger label, and routes all strings through
translate() with real es/ja/ko/zh translations. Removes the now-dead
buildComboboxEntries helper. Also adds the missing scrollbar-sleek class
the old list omitted (was failing pnpm lint).
