Local browser_navigate cold-starts the agent-browser daemon and Chromium;
60s was too short on slow Linux hosts and timeouts discarded stderr,
leaving users with a generic failure. Use a 120s floor on first open,
inject --no-sandbox in Docker, include captured daemon output plus install
hints when commands time out, and show "Failed to open" in the desktop
tool chip when navigation returns success=false.
Embeds reach out to third parties on render, so default to a placeholder that
mirrors the tool-approval UX: "Load <service>" (this embed) or "Always allow
<service>" (persisted). A desktop-local store ($embedMode ask|always|off +
per-service allowlist) gates the fetch with zero gateway round-trip; an
Appearance setting controls the global default. Local renderers (mermaid, svg,
alerts) are never gated. Addresses review feedback on outbound third-party
requests.
A clarify/approval/sudo/secret prompt blocks the turn on the user, but the UI
treated it as an in-flight turn: the "thinking" timer kept ticking and Esc
interrupted the run — discarding a question you might want to come back to. Add
$activeSessionAwaitingInput (the pet's awaitingInput concept, scoped to the
active session) and use it to suppress the stall indicator and disarm Esc while a
prompt waits. Clear the session's prompts (and needsInput) on Stop and on turn
end so a resolved/aborted turn can't leave a dead panel or a stuck "needs input"
dot.
The inline clarify panel used its own card tokens, an animated ring, and
oversized spacing — out of step with every other tool row. Rebuild it on the
shared --ui-*/--conversation-* tokens: a compact panel, letter-key badges
(A/B/C…) that double as a/b/c… shortcuts, an inline content-sizing "Other" field
(CSS field-sizing — no view swap, no layout shift on focus), and a Continue
button so picking an option selects rather than auto-sends. Selection lives on
the letter badge alone (solid primary; outlined while Other is focused-but-empty).
Also settle the panel into the standard tool block once the turn stops running,
so a stopped turn no longer strands a live, unanswerable prompt.
Add a content-agnostic Zoomable primitive (useZoomPan hook + overlay viewer):
click to open full-screen, wheel-zoom toward the cursor, drag to pan, toolbar
zoom/reset, and an optional copy action. Wire Mermaid diagrams into it with
copy-as-PNG; reusable for other inline content later.
Wire the embeds module into the markdown surface: bare provider autolinks unfurl
to inline embeds, ```mermaid/```svg fences route to the rich renderers, and
`> [!NOTE]`-style blockquotes become alert callouts. Labeled links stay plain.
Per-kind renderers, each a lazy split chunk: plain-iframe video/maps (wheel
chains to the transcript; maps gate scroll behind ⌘), the in-document
blockquote-script path for X/Instagram, the dark Spotify player, and the
YouTube iframe. Adds Mermaid and DOMPurify-sanitised SVG fences and GFM alert
callouts, all sized to 33dvh and theme-matched to avoid white color-scheme
artifacts. Main-process stamps a Referer on YouTube embed requests.
Pure, synchronous URL→descriptor matchers for YouTube, Vimeo, Instagram,
Pinterest, TikTok, X, Spotify, Google Maps and OpenStreetMap, plus the shared
embed primitives (error boundary, fail card, escape-html, dark-mode hook,
sizing token). Declares the mermaid + dompurify deps used by the fenced
renderers.
Bring apps/desktop and ui-tui to a clean state for typecheck, eslint,
and prettier:
- Run prettier across both trees (printWidth/wrap drift; prettier is not
CI-enforced for these JS projects, so main had accumulated drift).
- Apply eslint --fix for padding-line-between-statements and perfectionist
import/export sorting.
- Manual fixes for non-auto-fixable rules:
- remove unused node:net import in electron/main.cjs (uses Electron net)
- replace inline `typeof import(...)` annotations with top-level
`import type * as EnvModule` in two ui-tui test files
- scoped eslint-disable no-control-regex on intentional sentinel/ANSI
regexes (mathUnicode.ts, text.ts)
- resolve react-hooks/exhaustive-deps per-case: correct swapped/missing
deps, collapse redundant session.* members, and justified disables on
settings mount-only data-load effects to preserve run-once behavior
No behavior changes; test pass/fail counts are unchanged from the main
baseline.
Alt+wheel now scales about the pixel under the pointer instead of growing from a
corner, so the pet stays put under the cursor instead of running away. In-window
shifts its top-left; the overlay repositions its OS window (cursor-anchored on
wheel, bottom-center for slider-driven changes).
Hold Alt/Option and scroll over the mascot to resize it (same on Mac and
Windows); the modifier keeps a plain scroll passing through to the page. The
gesture drives the same `display.pet.scale` path as the settings slider.
The popped-out overlay grows its OS window to fit the pet at any scale (anchored
bottom-center) so the sprite is never clipped by the window edge, and the
in-window pet re-clamps against its actual size so growing near an edge can't
crop it. Also makes the overlay click-through per-pixel: only solid sprite
pixels (plus bubble / mail button) are interactive, transparent margins pass
clicks through.
When idle with a top-level delegate_task still in flight, render a static,
shimmering system-note at the transcript tail instead of a spinner (which
reads as "stuck"). Reuses the shared steer / slash-status chrome (centered,
0.6875rem, muted, Codicon) so it sits in the thread like every other meta
line, and mirrors the primary child's latest stream line, falling back to
generic copy. i18n across en/ja/zh/zh-hant; markdown prose/heading rhythm
tuned so a re-entered turn breathes.
Extends the pane store with heightOverride (alongside widthOverride) and a
get/set/clear API, and wires the pane shell + desktop controller so the
bottom-row terminal pane can be resized on the Y axis with its size persisted.
Adds a CodeMirror 6 spot editor to the right-rail file preview so users can
make quick edits in-app without leaving for an IDE. Entering edit mode is a
pure in-place swap of the read view — same fixed-height header, same gutter
geometry/typography (mirrors SourceView 1:1) so nothing shifts — toggled via
the Edit button, a bare `e` when the pane is hovered/focused, or the tab.
- Save path is transport-agnostic (writeDesktopFileText): local Electron IPC
or a new hardened POST /api/fs/write-text on the dashboard server (path
validation, parent-must-exist, regular-files-only, size cap, atomic
temp-file + os.replace), behind the existing auth middleware.
- Stale-on-disk guard re-reads before writing and offers overwrite vs
discard-and-reload instead of clobbering external/agent edits.
- VS Code-style modified dot on the tab; ⌘/Ctrl+S and ⌘/Ctrl+Enter save,
Esc cancels; GitHub highlight style matched to the read view's Shiki theme.
- Typing stays render-free (draft in a ref; dirty flips once at the boundary).
A stale-index render race in assistant-ui (a just-shrunk thread rendered
at an old message index during a session switch / teardown) throws
errors like "tapClientLookup: Index N out of bounds", "Cannot read
properties of undefined (reading 'type')", or "Tried to unmount a fiber
that is already unmounted". These bubble to the root ErrorBoundary and
latch the WHOLE desktop app on the "Reload window" fallback even though
the next render against fresh state would be fine.
Teach the root boundary to treat that small set of known-transient
renderer errors as recoverable: log them and schedule a next-tick
reset() so React re-renders against current state instead of stranding
the user on the fallback.
Auto-recovery is BOUNDED -- at most MAX_RECOVERIES (3) attempts within a
5s window -- so a genuinely persistent error can't spin the boundary in
a reset -> throw -> reset loop; after the budget is spent the fallback
is left up for the user. Manual retry (the button) resets the budget.
Only the root boundary auto-recovers; scoped boundaries keep their own
fallbacks, and unrecognized errors are never swallowed.
Tests: transient race recovers (fallback never sticks), a persistent
recoverable error stops at the cap and surfaces the fallback (proving
the loop is bounded), and neither a non-root boundary nor an
unrecognized root error auto-recovers.
Closes#41693. Supersedes #41787 by @izumi0uu, reimplemented with a
bounded recovery budget so a non-transient error can't loop forever.

Move terminal/execute_code/read_file preview compaction into agent.display so CLI, gateway, and Ink TUI all inherit the same labels that desktop introduced in #52321.
The shared preview keeps raw args intact while trimming display-only shell plumbing (`cd`, pipe tails, banner/status echoes) and read_file line ranges. Desktop now prefers backend `context` for live rows and keeps its TypeScript fallback only for hydrated history.
Make completed desktop tool rows read like useful activity labels instead of raw plumbing: terminal rows use a dispatch-style shell summarizer for agent wrappers, and read_file rows keep the action plus filename and requested line range.
The shell cleanup follows condensed-milk-pi's shape: split command compounds on real separators, strip pipe tails inside each segment, clean redirects/env prefixes, then classify setup/banner/status segments. Multi-command probes render as `first command + N commands`; the full command remains available in copy/detail.
Read rows now render as `Read package.json` or `Read main.ts L25-34`, using requested positive offset/limit and returned line numbers only as fallback for negative/unknown offsets.
ToolFallback rebuilt the `part` wrapper every render, defeating the
buildToolView memo and re-running a full JSON.stringify of the result on
every ~33ms stream delta. A /learn over a large directory (many ~100KB
tool results) saturated the renderer main thread (hang/throttle) and
spiked memory until it OOMd (crash).
- Re-derive a stable `part` from the referentially-stable args/result so
the view/copy memos hold across deltas.
- Clamp every inline-painted payload (detail, stdout/stderr, rawResult,
technical trace) to MAX_TOOL_RENDER_CHARS; the row's Copy button still
reads the uncapped view.detail for the full output.
Two ways the update overlay read as stuck even though the update was
streaming progress underneath:
- In-app (macOS/Linux) UpdatesOverlay: runStreamedUpdate forwards every
stdout line as a progress event with percent: null, and ingestProgress
wrote that straight through — clobbering the milestone percents (10/60)
so the bar fell back to indeterminate on every log line. Keep the last
percent when a line carries null.
- Staged install/update overlay: the bar is completedCount / totalCount,
which counts only *finished* stages, so a long first stage pinned it at
"0 of 2" / 0% until the stage ended. Count the running stage as half a
unit so the bar advances during the stage (the per-stage spinner already
shows which step is live).
Both are display-only; no stage/event semantics change. (The Windows
hermes-setup Tauri progress UI in apps/bootstrap-installer has the same
counter-only-on-completion logic — parity follow-up.)
Ship the final pet-generation UX polish (provider picker behavior, step-2 cancel flow, banner integration, and visual consistency) and make saturated-chroma background removal C-op driven so hatch processing no longer hammers the machine during long runs.
Register previewable artifacts from the tool row, feed a session-scoped store,
and render compact rows above the composer. Remove the inline preview card.
Adds a compact right-edge prompt timeline for long desktop chat sessions, with hover previews, click-to-jump, active/hover row states, and pane hover-reveal suppression so the rail can live at the hard edge without opening side panels.
* feat(desktop): add Update now button to About panel
The About > Updates panel only surfaced "See what's new" when an update
was available, which just opens the changelog overlay — there was no way
to start the install directly from About. Add an "Update now" primary
button that opens the updates overlay (for apply progress) and kicks off
the install for the active target (backend in remote mode, else client).
* feat(desktop): PR-style file diffs in chat
Render write_file/edit_file/patch as a reviewable diff instead of raw
result JSON, closer to a Cursor/T3 per-edit review.
- Unified diff via FileDiffPanel: strip git file-header + @@ hunk noise,
drop the +/- gutter, color by line with a 2px gutter accent, full-bleed
to the card, transparent context lines, compact scroll height.
- Header shows filename + language icon + +N/-N stats; full path moves to
a hover tooltip (no Edited verb, no ms).
- Treat the three file-edit tools uniformly (isFileEditTool); read diff
from inline_diff or patch's diff field; suppress raw-arg detail.
- Reusable FileTypeIcon primitive sharing the code-block icon mapping
(codiconForFilename), codicon fallback.
- Per-row scaffolding fade (not the group wrapper, which trapped child
opacity); expanded edits stay full, collapsed fade; keyboard-only focus
lift. Hide diff-less rehydrated creates that read as dupes.
* style(desktop): lead --dt-font-mono with bundled JetBrains Mono
Code/diff blocks preferred a system Cascadia Code before the bundled
JetBrains Mono, so they drifted from the terminal (which leads with
JetBrains Mono) on machines where Cascadia is installed. Reorder so every
mono surface uses the face we actually ship.
* feat(desktop): syntax-highlight inline diffs via Shiki
Unify the diff renderer onto the same Shiki path as code blocks: highlight
the marker-stripped change content in the file's language, then a per-line
transformer layers the add/remove tint + gutter accent on top. Falls back
to the plain color-only renderer when the language is unknown, over budget,
or while Shiki loads.
- shikiLanguageForFilename(): extension → bundled-language id (shared
filename-token helper with codiconForFilename).
- code display:grid so full-width line tints don't double with newline
nodes; theme surface stripped so context lines stay transparent.
* style(desktop): use github-dark-dimmed for inline diffs
The vivid github-dark-default tokens read harsh behind the add/remove
tint in dark mode; switch the diff's dark theme to GitHub's lower-contrast
dimmed palette. Light mode and code blocks are unchanged.
* style(desktop): dim code-block syntax theme + share with diffs
Apply github-dark-dimmed to code blocks too (not just inline diffs) and
export one shared SHIKI_THEME so the two highlighters can't drift. Lower
contrast reads easier at our small code size in dark mode.
* style(desktop): soften shiki token contrast in dark mode
github-dark-dimmed only dims the background, which the diff/code surfaces
strip — so the bright token foregrounds were unchanged. Pull saturation +
brightness back a touch (hues preserved) on .shiki in dark mode for both
code blocks and inline diffs.
Share one SHIKI_THEME (github-dark-dimmed) across code blocks and inline
diffs so they can't drift, and pull token saturation/brightness back via a
`.shiki` dark-mode filter. The dimmed theme alone only changes the
background — which both surfaces strip — so the bright foregrounds needed
the filter to actually calm down.
Unify the diff renderer onto the same Shiki path as code blocks: highlight
the marker-stripped change content in the file's language, then a per-line

#43496 added a per-provider hide-all sentinel ('provider::') so emptying a provider in the Edit Models dialog stopped re-expanding its defaults. That fixed the single-provider case, but the dialog's toggle handler seeds its working set from effectiveVisibleKeys(), which strips ALL sentinels before returning. So persisting after any toggle silently dropped every OTHER provider's hide-all sentinel; those providers then looked 'never customized' and re-enabled all their models on the next render.
Split resolution into two functions:
- resolveVisibleKeys(): stored keys + curated default expansion, with hide-all sentinels PRESERVED — the canonical working set the toggle handler mutates and persists.
- effectiveVisibleKeys(): resolveVisibleKeys() then strips sentinels, for display only (unchanged contract).
Move the toggle set-computation into a pure, unit-tested toggleModelVisibility() that seeds from resolveVisibleKeys(), so sibling sentinels survive the persist. Add regression tests that drive the real toggle handler across multiple providers.
Follow-up to #43496; completes the fix for #43485 (cross-provider case).
Add the in-window floating pet (sprite, speech bubble, contact shadow,
profile-scoped, resize-safe) and a pop-out always-on-top overlay window
with gestures and notifications. Add the Cmd+K pet picker page plus the
appearance gallery and size slider in settings. Includes the pet stores,
electron overlay wiring, i18n strings, and store tests.
- Peel-off undock drops the floating composer under the cursor (centered
horizontally, preserving the vertical grab offset) instead of snapping to
the docked corner.
- Unify the / · @ · ? completion drawer and the attach (+) menu onto one
shared glassy panel primitive (composerPanelCard): smallest theme font,
hairline border, nous shadow; floats off the composer, inset from the left.
- Directive chips: Backspace removes the chip + its auto-inserted trailing
space atomically (no orphaned space), and a phantom trailing block left by
contenteditable no longer falsely expands the composer to two rows.
- Model picker: scroll area capped at max(150px, 30dvh); footer rows aligned
(matching icons, dropped a redundant margin).
- Composer focus shifts the border ~15% toward foreground (no fill change);
input is cursor-text; trimmed control icon/button sizes.
Remote displays (RDP/SSH/X11) silently disable GPU hardware acceleration with
only a console.log, leaving the user unaware that software rendering is
active. Expose the detected reason over IPC and surface a dismissible banner
in the renderer.
The global body { user-select: none } left log surfaces unselectable. Opt them
back in via the existing data-selectable-text convention — at the shared
LogView primitive (boot-failure + bootstrap install overlays) plus Command
Center recent logs, toolset post-setup output, notification detail, and
subagent stream/file lines.
A failed turn leaves a red error banner inline in the transcript. These
errors are renderer-local state (never persisted) and stay pinned to the
message until the session is reloaded, so a stale, no-longer-relevant
error (e.g. a transient provider/inference error) lingers with no way to
clear it.
Add an 'x' dismiss button inside the existing MessagePrimitive.Error
block. Clicking it clears the error from BOTH the live $messages view
and the per-runtime session cache — the view first, because
preserveLocalAssistantErrors re-grafts any still-errored message it finds
in the view onto the next session.info flush, so clearing only the cache
would let the heartbeat resurrect the banner. A bare error placeholder
(no streamed content) is dropped entirely; a turn that streamed partial
output before failing keeps its text and just sheds the error.
The control only renders when an onDismissError handler is wired, so
secondary/embedded Thread usages are unaffected. Adds the dismissError
string to all four locales (en/ja/zh/zh-hant) and two behavior tests.

A multi-MB message (logged bundle, huge tool dump) froze the renderer
before any paint: Streamdown runs `preprocess` + `marked` lex over the
whole string synchronously in a useMemo, an uninterruptible long task
that no try/catch or content-visibility can help (our JS runs before the
browser ever skips layout). Tiered fix:
- Message gate: past 200KB, bypass markdown entirely and render the raw
text in `content-visibility:auto` line-chunks — synchronous work is
bounded to a string split, the browser virtualizes layout natively,
and every line stays in the DOM (selectable, find-in-page).
- Code-block budget: past 3k lines / 150KB, skip Shiki (which emits a
span per token) and render plain, chunked the same way.
- Collapse/expand: a reusable ExpandableBlock clamps code blocks and the
huge-text fallback to a 120px preview with a gradient + chevron,
expanding to 300px. The inner element is always a scroll container so
the content-visibility chunks stay lazily laid out in both states.
No content is ever dropped; the copy button (card header) always yields
the full block.
unicode-bidi:plaintext (#44596) resolves text direction per line, but
list markers and the blockquote border are box chrome driven by the CSS
direction property, which plaintext never sets, so an RTL list renders
its numbers stranded at the far left edge. CSS cannot close this gap
(:dir() only reads the dir attribute, never plaintext resolution), so
ul/ol/blockquote carry dir="auto" and the browser resolves their box
direction natively while the plaintext rules keep owning the text.
Inline code carries dir="ltr", which HTML's auto algorithm skips,
matching the no-vote contract the CSS isolate already gives it.
