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.
Track top-level delegate_task work that dispatches in the background and
re-enters as a fresh turn. $backgroundResume returns {count, activity} for
the active session while idle — count of parked tasks plus the primary
child's latest stream line (tool/progress/thinking) when readable.
Use the app's amber warn color for the unsaved-edits tab dot (was inheriting
the label text color) and add a tab-bg ring + soft drop shadow so it stays
legible where it overlaps the filename.
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.

resumeSession's warm-cache fast-path trusted the
storedSessionId -> runtimeId -> ClientSessionState mapping without
checking the cached state still BELONGS to the session being resumed.
A pooled profile backend that gets idle-reaped and respawned
(pruneSecondaryGateways) re-mints runtime ids, so a recycled id can
resolve to a live-but-DIFFERENT session's cache entry. The only
existing guard was a session.usage 404 -- that catches a fully-dead
runtime id, but a recycled id still 200s, so the fast-path happily
painted the wrong transcript under the current route (open chat A,
chat B loads).
Fold the belongs-to check into a single takeWarmCache() helper used at
BOTH cache reads -- the early transcript-keep decision and the fast-path
itself -- so a cross-wired entry can't even briefly flash a stale
transcript before the full resume repaints. On a mismatch the helper
purges both stale map entries and reports a miss, falling through to a
full resume that rebinds a correct runtime id. The full-resume path
already guards its final paint with isCurrentResume(), so only the
cached fast-path was missing the belongs-to check.
Pre-existing bug from the initial desktop app (#20059); not introduced
by the session-switch perf work (#49807), which left these lines
untouched.
Tests: two cases in use-session-actions.test.tsx driven through a
harness that owns the two cache maps -- a cross-wired mapping is
rejected + purged (the bug), and a correctly-wired cache still serves
from memory with no needless refetch (no perf regression).
Supersedes #50464 by @professorpalmer, reimplemented to also guard the
early transcript-keep read (whole-class fix, not just the fast-path).

* feat(moa): expose MoA presets as selectable virtual models
Reconstructed onto current main (PR #46081's base had diverged with no common
ancestor, marking the PR dirty so CI never dispatched). MoA is now a virtual
provider: each named preset is a selectable model under provider 'moa', and the
preset's aggregator is the acting model that answers and calls tools.
Reference models fan out in parallel via a bounded ThreadPoolExecutor (the same
batch pattern delegate_task uses) — all references dispatched at once, collected
when every one finishes, then handed to the aggregator. Output order is
preserved, failures and the MoA-recursion guard stay isolated per reference.
- Removed the old mixture_of_agents model tool and moa toolset.
- Added moa as a virtual provider in the provider/model inventory.
- /moa is shortcut behavior over model selection (default preset / named preset
/ one-shot prompt).
- Dashboard + Desktop manage named presets; presets appear in model pickers.
- Parallel reference fan-out in agent/moa_loop.py with regression test.
* fix(moa): thread moa_config through _run_agent to _run_agent_inner
The reconstructed gateway MoA wiring declared moa_config on _run_agent (the
profile-scoping wrapper) and used it inside _run_agent_inner, but the wrapper
never forwarded it — _run_agent_inner had no such parameter, so the runtime hit
NameError: name 'moa_config' is not defined on the compression-failure session
sync path. Add moa_config to _run_agent_inner's signature and forward it from
both wrapper call sites (multiplex and non-multiplex). Caught by
tests/gateway/test_compression_failure_session_sync.py on CI shard test(4).
* fix(moa): classify moa as a virtual provider in the catalog
The moa virtual provider has no PROVIDER_REGISTRY/ProviderProfile entry, so
provider_catalog() fell through to the default auth_type="api_key" with no
env vars — tripping two catalog invariants:
- test_provider_catalog: api_key providers must expose a credential env var
- test_provider_parity: every hermes-model provider must be desktop-configurable
moa already declares auth_type="virtual" in HERMES_OVERLAYS; consult that
overlay as an auth_type fallback so the catalog reports moa as virtual (no real
credential, no network endpoint). Exempt virtual providers from the desktop
parity union check the same way 'custom' is exempt — derived from the catalog,
not a hardcoded slug, so future virtual providers are covered too.
Statusbar items declared a 'title' string (e.g. YOLO, gateway health,
agents, cron, version, context usage) that was populated by
use-statusbar-items.tsx but never forwarded to the rendered DOM in
StatusbarControls — so every statusbar button/menu/text/link had no
hover hint.
Wrap the four render branches (menu trigger, text, link, action) in
the existing 'Tip' component from components/ui/tooltip.tsx. Tip is
self-contained (carries its own Provider), instant (delayDuration=0),
themed (bg-foreground/text-background, auto-inverts per theme), and
already in use elsewhere in the desktop shell. Renders the child
untouched when label is falsy, so items without a title stay
zero-cost.
Collapse the duplicated cold-resume / lazy-watch / create scaffolding into
shared helpers: _deferred_session_record (the live-session dict minus the
agent), _lazy_resume_info (the not-yet-built session.info), _claim_or_reuse_live
(lock + double-checked register-or-reuse), and _schedule_agent_build (the
pre-warm timer). Net -12 lines, three copies of the ~30-key session dict and
the lazy-info block down to one each. No behavior change.
Per review: gating the faster path behind a `defer_build` flag that the
only caller always sends is pointless. Flip it — `session.resume` now
defers the agent build by default for every caller (desktop + Ink TUI);
a caller that needs the agent built synchronously passes `eager_build:
true` (used by the build-race test). The desktop no longer sends a flag.
While verifying the flip, fixed two real parity gaps the deferred path
had vs the old eager (`_init_session`) path:
- `_enable_gateway_prompts()` was never called on a deferred resume, so
approvals/clarify wouldn't route through the gateway prompt callbacks.
- `_start_agent_build` never wired `background_review_callback` /
`memory_notifications`, so a deferred-built session's self-improvement
"💾 …" summary leaked to stdout instead of rendering in-transcript.
Wiring it there also fixes it for `session.create` sessions, which
build through the same path.
ACP is unaffected (it uses its own session_manager, not this RPC); the
Ink TUI already consumes the same lazy `info` shape from session.create
and upgrades on the later `session.info` event.
Switching sessions in the desktop app could freeze the whole UI for
several seconds on heavy, tool-rich chats. Root causes and fixes:
- Cold `session.resume` built the AIAgent (MCP discovery, prompt/skill
build) *before* returning, and the desktop awaits that RPC before it
paints — so the entire switch blocked on the build. Add an opt-in
`defer_build` resume path (the contract `session.create` already uses):
return the full display transcript immediately, register an upgradable
live session, and pre-warm the agent on a short timer. The persisted
runtime identity (model/provider/base_url/api_mode/reasoning/tier) is
restored on the deferred build so it can't drop the provider.
- Nothing bounded how many in-memory agents accumulate; a user who
reconnects often piled up detached sessions for the full 6h TTL. Add a
soft LRU cap (`max_live_sessions`, default 16) that evicts the
least-recently-active DETACHED sessions (no live client) — never a
running, awaiting-input, mid-build, or live-transport one. Reopening
re-resumes from disk.
- On the prefetch-hit cold-resume path, skip rebuilding a throwaway
merged-message array (and its 1000-entry Map) when the prefetch already
painted the exact transcript; the downstream sameMessageList guard
already drops the publish, so it was pure main-thread cost.
The desktop opts into `defer_build` for every non-watch cold resume; the
eager path stays for CLI/TUI and existing callers.
Add a hover/focus "Remix" action on each completed draft card in the
generation grid. It re-runs generation with the chosen draft fed back in
as the reference image, keeping the same prompt and staying on step 2 so
the user can explore variations without starting over.
Because regenerating is slow and replaces the current drafts, the first
remix shows a one-time confirmation; the acknowledgement is persisted so
subsequent remixes fire immediately.
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.
The fixed "up to 5 minutes" wording undersells the slow quality-first path
(OpenAI image via OpenRouter), where a full hatch can run far longer. Use an
open-ended "several minutes" instead so the banner stays honest across the
fast and slow providers.
The quality-first default (OpenAI image via OpenRouter) is slow, and a full
hatch fans out ~8 rows with up to 3 retries each (300s/call) across 2 parallel
waves, so the absolute backend worst case is ~30 min. The old ceilings fired
mid-run:
- per-image HTTP call: 180s -> 300s (a single cold row can exceed 3 min)
- drafts RPC: 240s -> 420s (single wave, no retries — 7 min is ample)
- hatch RPC: 420s -> 1hr (sits above the ~30 min backend worst case)
The hatch ceiling is intentionally well above the realistic max so the frontend
never throws "request timed out" before the backend has exhausted its own
retries. The background-resumable notification path remains the real UX safety
net — the user can close the modal and get pinged on completion.
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.
OpenRouter/Nous image gen now runs a quality-first model chain by default:
attempt the highest-fidelity OpenAI image model first, then fall back to
Gemini 3 Pro Image when it's access-gated/unavailable/times out. An explicit
OPENROUTER_IMAGE_MODEL / config model override pins one model with no fallback.
Atlas validation rejects malformed model output instead of shipping it: adds a
per-state collapse guard (a single sliver/fragment row no longer passes because
other rows are healthy), on top of the existing postage-stamp + multi-pose
checks.
Desktop: pet-gen native notifications are now "global" (not tied to a chat
session), so a background generation started from the command center fires an
OS notification when the user is away even with no active session. Adds a
neutral "This can take up to 5 minutes." banner on step 1, and lets the
provider picker auto-size.
Tests updated/added for the OpenRouter fallback chain, the collapse guard, and
the global notification path.
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.
Regression for the refText crash: attachmentDisplayText and
optimisticAttachmentRef must return null (not throw) when handed an
undefined/null attachment hole, so the submit path can't reproduce
"Cannot read properties of undefined (reading 'refText')".
A session switch or draft restore can leave undefined/null holes in the
composer attachments array. AttachmentList was guarded against this in
#49624, but the sibling submit path was not: submitPromptText maps the
same array through attachmentDisplayText/optimisticAttachmentRef and
buildContextText (a.kind / a.label / a.refText), so a hole threw
"Cannot read properties of undefined (reading 'refText')" — an uncaught
renderer error that blanks the chat pane and shows "Desktop app link
offline".
Close the whole bug class:
- attachmentDisplayText / optimisticAttachmentRef no-op on a falsy
attachment (shared chokepoint, also protects thread.tsx drop handler).
- submitPromptText filters falsy entries from the source array, and
buildContextText filters its (possibly post-sync) input before reading
fields.
