The settings OverlayMain has a titlebar-height top pad (no bottom pad), so
the full-panel LoadingState centered in the band beneath it and read low.
Cancel the top pad on the loader so it centers in the whole card; the one
inline (mid-panel) memory loader switches to a plain min-height PageLoader
so it's unaffected.
Revert the dedicated System section: Window Translucency + UI Scale move
back to Appearance, and Haptics returns to its titlebar-only home. Keep
computer awake now lives as a device-local toggle at the top of Advanced
(a ConfigSettings section-specific extra, like the Model block), keeping
the statusbar quick-toggle. Relocated i18n back to settings.appearance /
settings.config across all four locales.
Add a "keep computer awake" toggle (Claude-style) for long/overnight runs:
the renderer owns the device-local pref and mirrors it to the Electron main
process, which holds a single `powerSaveBlocker('prevent-app-suspension')` —
the same authority split as translucency. Surfaced as a statusbar quick-toggle
and a Settings row.
Introduce a dedicated System settings section (device-local machine prefs) and
de-crowd Appearance by moving Window Translucency + UI Scale into it (both are
main-process/window-owned, not visual theme). Give Haptic Feedback its first
Settings home there too (the titlebar quick-toggle stays). Relocated i18n copy
into `settings.system` across en/zh/zh-hant/ja; wired the `system` route into
the SettingsView union + allowlist + nav.
* fix(desktop): scope multi-pane model UI and stabilize tile chrome
Composer model controls were still keyed off the primary session globals, so every tile showed the same model and a busy primary blocked switches in idle panes. Bind the pill/menu/select path to SessionView, force lone session-tile headers (incl. after tab cycle), and persist strip order so add/remove/switch stops scrambling adjacent panes.
* fix(desktop): scope preset effort/fast writes per surface, simplify tile order sync
A tile's model pick still pushed effort/fast onto the primary composer globals via applyModelPreset — scope it to the surface (primary → globals, tile → its session slice). Tile order persistence drops the before-stamping walk for a plain sort by tree encounter order; restore replays the array sequentially so array order is strip order.
* test(desktop): cover tile strip-order + selection-home; fix stale docs
Extract syncTileStripOrder's sort into a pure `orderTilesByTree` and the
selection listener's guard into `selectionHomesToWorkspace` (same shape as
the PR's lone-header extraction), then unit-test both — the two store
behaviors that shipped without coverage. Correct the `anchor`/`before` docs
(now persisted, not in-memory) and note that a tile's effort/fast edit still
writes the shared per-model preset even though the session write is scoped.
* fix(desktop): drop forbidden import() type annotations in model tests
`importOriginal<typeof import('…')>()` trips consistent-type-imports (error)
and reddens the desktop lint job. Switch to the repo's accepted top-level
`import type * as X` + `typeof X` form, matching skills/index.test.tsx.
* perf(desktop): idle-mount boot-hidden panes off the cold-start critical path
The layout tree keeps a chrome-hidden pane's content MOUNTED behind
display:none (so toggling back is instant) — but that means files, preview,
review (Shiki diff) and logs all mount their real content during first paint
even though none are visible at launch (fresh profile: no cwd, review off,
no preview target, logs not in the default tree). First paint only needs
sessions + workspace + statusbar; the rest is pure app-mount tax, the one
cold-start lever that's actually in our code (Electron startup and the
un-splittable bundle eval are not).
Wrap those four pane renders in <IdleMount>: mount on requestIdleCallback
(2s timeout fallback), then stay mounted. Idle fires within a frame of first
paint, so a hidden pane is warm before it can be revealed — zero UX change,
the instant-toggle contract intact. Degrades to eager mount where rIC is
absent (jsdom/tests), so no behavioral fork.
* refactor(desktop): collapse the four idle-mount wrappers into one idle() helper
findBy*/waitFor default to a 1000ms deadline, which is too tight for
async-heavy settings panels (radix menus + refetch chains) when the full
suite runs under xdist CPU contention in CI. toolset-config-panel.test.tsx
has reddened unrelated PRs multiple times with `Unable to find ...` timeouts
that pass on re-run — the textbook contention flake.
Bump asyncUtilTimeout to 5000ms in the shared ui setup. Success still
resolves the instant the node appears; the wider deadline only absorbs a
starved runner, so happy-path speed is unchanged and only genuine failures
wait longer.
Two tool-render wins during streaming / on session switch:
1. Every ToolEntry did useStore($activeSessionId)+useStore($currentCwd), so any
session or cwd change re-rendered *every* mounted tool row — but they're only
read inside the preview-artifact effect. Read .get() at fire time instead
(the effect only runs when a previewable target appears); no subscription.
2. memo() AnsiText + CompactMarkdown. Their text props are string values
(value-equal across renders), so memo skips the re-render — and the per-tick
ANSI parse / Streamdown re-run — when a parent ToolEntry re-renders on an
unrelated stream delta.
No behavior change. typecheck + eslint clean; tool fallback tests green (30).
buildToolView ran prettyJson (JSON.stringify + clamp) on part.args AND part.result
for EVERY tool row, on every rebuild:
- rawArgs was dead — assigned + typed, never read anywhere. Removed.
- rawResult is only rendered by the web_search raw-JSON drilldown, yet was
serialized for read_file/terminal/every tool. Moved to a memoized, web_search-
only computation in the consumer (fallback.tsx), so a 100KB read_file result
is no longer stringified just to be discarded.
No behavior change (web_search drilldown identical; clamp still applies via
prettyJson). The oversized-result guard test retargets from view.rawResult to
prettyJson (its real layer now).
typecheck + eslint clean; fallback-model tests green (26).
Both drag handlers wrote to nanostores on every pointermove — the pane sash via
setPaneWidth/HeightOverride / setTreeSplitWeights (relayouts the whole pane
tree), the preview console sash via consoleState.setHeight (reflows webview +
split). pointermove outpaces 60fps, so that's several store-driven relayouts per
frame during a drag.
Stash the latest clamped value and apply it once per frame in a requestAnimation-
Frame (the same pattern drag-session.ts / use-popout-drag.ts already use);
cleanup cancels the pending frame and commits the final position. Behavior
identical, just one relayout per frame instead of per event.
typecheck + eslint clean; preview-pane tests green.
Rewrite of the paradigm, not just a cheaper version of it. Before, any file
mutation bumped a contentless $workspaceChangeTick and the tree re-read EVERY
loaded directory to diff — the parent state was never told what actually changed.
Now the mutation carries its path:
- workspace-events accumulates the changed dir(s) (dirname of an absolute tool
path) and exposes consumeWorkspaceChange(); an opaque mutation (terminal, or a
relative/unresolvable path) sets `full` instead.
- gateway-event passes toolChangedPath(payload) through on tool.complete.
- revalidateTree(cwd, change) re-reads ONLY the changed dirs that are loaded and
patches just those subtrees — root + untouched folders never hit the FS or
re-render. Full recursive reconcile is kept as the fallback for `full`.
So a write in one folder no longer crawls the whole tree; the opaque terminal
case still self-heals via the full path. Safe fallback everywhere a path can't be
resolved, so no change is ever missed.
typecheck + eslint clean; use-project-tree / right-sidebar / gateway-events tests green.
revalidateTree runs on every $workspaceChangeTick (mutating-tool completion,
coalesced ~500ms). Two costs per tick, gone:
1. clearProjectDirCache() wiped the gitroot + gitignore caches. But listings are
read fresh every time (readProjectDir never caches them), so the wipe bought
nothing except forcing a full re-read of every ancestor .gitignore — each a
full readdir — for every loaded dir, every tick. Dropped; a .gitignore edit is
still picked up on the next full refresh (cwd/connection change / manual).
2. reconcile awaited each child dir serially, crawling a wide/deep tree one dir
at a time. Now Promise.all over siblings (order preserved), recursing per
loaded subfolder.
use-project-tree.test.ts + right-sidebar/index.test.tsx green (15). tsc + eslint clean.
Selecting a large changed file in the review pane froze it: FileDiffPanel with
no fullText + no showLineNumbers rendered SyntaxDiff over EVERY line — a full
Shiki highlight + thousands of mounted DOM nodes — because windowing was tied to
showLineNumbers/fullText and the review call had neither.
Decouple windowing from the gutter:
- `windowed = showLineNumbers || virtualized`; windowed paths always render the
fixed-row chunked body (TokenizedDiffBody chunked / PreviewDiffRows), never
SyntaxDiff, so only visible rows mount.
- New `virtualized` prop → windowed scroller WITHOUT the line-number gutter.
- Review passes `virtualized` + the preview's fill className.
Preview (showLineNumbers + fullText) and tool-card (compact) render byte-for-byte
as before — the gutter body just reads the same chunked window it already used,
and the no-fullText+highlight case (previously SyntaxDiff) now windows too.
tsc + eslint clean. Visual paths preserved by construction; needs an in-app
eyeball on a large review diff.
Every API iteration computed `total_chars = sum(len(str(msg)) ...)`, which
str()-serializes the ENTIRE history — including base64 images and large tool
results — just to take its length, then called estimate_request_tokens_rough,
which walked the messages a SECOND time (it re-runs estimate_messages_tokens_rough
internally, already computed one line above).
Now derive both from one image-stripped message estimate:
approx_tokens = estimate_messages_tokens_rough(api_messages) # once
request_pressure_tokens = approx_tokens + tools_tokens # == old value
total_chars = approx_tokens * 4 # log/metric only
request_pressure_tokens is byte-identical to the old
estimate_request_tokens_rough(api_messages, tools=agent.tools or None) (no
system_prompt arg → messages + tools). total_chars only feeds a verbose log and
the pre-api-request hook's request_char_count, so a rough proxy is fine and it no
longer balloons on image turns. On the TTFT critical path for every call.
tests/agent/test_model_metadata.py + test_compressor_image_tokens.py green.
One shared `stableArray(prev, next)` helper replaces the duplicated
element-equal/keep-prev logic in both stores, and freezes the shared ref so a
future in-place mutation fails loud instead of silently corrupting the cache.
Computed return type is now `readonly string[]` (it always was, immutably).
* feat(desktop): add custom endpoint settings (supersedes #42745)
Salvages PR #42745 (elashera:custom-endpoints-desktop), which could no
longer merge cleanly against main. Re-integrated the work onto current
main and reconciled the conflicts:
- Settings nav: wired the new 'Custom Endpoints' provider sub-view into
main's data-driven navGroups/OverlayNav layout (PR predated that
refactor) and added it to PROVIDER_VIEWS.
- providers-settings: kept BOTH main's LocalEndpointRow affordance and
the PR's fuller CRUD panel; unified ProvidersSettingsProps to carry
onClose + onConfigSaved + onMainModelChanged.
- web_server: kept main's _normalize_main_model_assignment + api_key
propagation AND the PR's provider base_url lookup in
_apply_model_assignment_sync.
- model_switch: dropped the PR's bare direct-custom-config picker block;
main already implements it (source='model-config', with live model
discovery). Updated the salvaged test to assert main's behavior.
- Merged additive import/type blocks in hermes.ts and types/hermes.ts.
Backend endpoints, i18n labels (en/ja/zh/zh-hant), and the
custom-endpoints-settings.tsx panel carried over. 28 custom-endpoint
tests pass.

* fix(tui): recognize standard DSR cursor position reports in input parser
The CURSOR_POSITION_RE regex only matched DECXCPR reports (CSI ? row;col R)
but not standard DSR reports (CSI row;col R without the ? marker). Terminals
that respond to CSI ? 6 n with the plain DSR form had their cursor position
reports fall through to parseKeypress, where they were inserted as literal
text — garbling the composer input with escape sequences like ESC[22;1R.
Fix: make the regex match both forms. For the standard form (no ?), only
treat it as a cursor position report when row > 1, since modified F3 keys
(Shift+F3 = CSI 1;2 R, etc.) always use row 1 and are genuinely ambiguous
with row-1 cursor reports.
* fix(tui): reject invalid row-zero DSR cursor position reports
Follow-up to the standard-DSR recognition fix. The row guard rejected
only row === 1, which let CSI 0;col R (row 0, no ? marker) through and
misclassified it as a cursorPosition report. Terminal coordinates are
1-indexed, so row 0 is an invalid DSR report and must remain
unclassified.
Change the guard to row <= 1 to match the stated 'row > 1' semantics,
and add a boundary test asserting CSI 0;col R is not emitted as a
response.
Supersedes #48762; incorporates review feedback from that PR.

* fix: speed up CLI /model picker by skipping non-current custom provider probing
The CLI /model picker calls build_models_payload() with default
probe_custom_providers=True, which live-fetches /v1/models from every
saved custom endpoint on every open. The GUI/desktop picker already
passes probe_custom_providers=False for snappiness.
Match the GUI behavior: skip probing non-current custom providers, but
still probe the current one so its model list stays accurate. Users can
force a full re-fetch with /model --refresh.
Fixes#65650
Related: #63583
* fix(cli): forward force_refresh to model picker probe flags
When /model --refresh is used, the CLI model picker must probe all
custom providers to refresh their model lists — not skip them.
Normal bare /model still skips non-current probes for speed.
Mirrors the existing desktop/TUI behavior. Add regression test for
both normal and refresh flag forwarding.
Fixes#65650
* fix: auto-save discovered models to config for discover-once caching
After a successful /v1/models probe, persist the discovered model list
back to config.yaml under the matching custom_providers entry. This
makes discover_models: false meaningful out of the box — users get a
populated cache after the first probe instead of a stale 1-model list.
- Add _save_discovered_models_to_config() helper
- Call after successful fetch_api_models in section 4 probe path
- Skip config write when model list hasn't changed
- Idempotent — no-op on empty api_url or model_ids
Tests: 4 new tests covering auto-save, empty-probe skip, unchanged
skip, and no-op-on-empty-args. All 4 pass.

grok-4.5 is xAI's newest release (their versioning is non-monotonic:
4.5 > 4.20) and is the model xAI's own docs use for the server-side
x_search tool. Users who explicitly pinned x_search.model keep their
choice; everyone else picks up the new default via the config
deep-merge — no _config_version bump needed.
- tools/x_search_tool.py: DEFAULT_X_SEARCH_MODEL
- hermes_cli/config.py: DEFAULT_CONFIG x_search.model + comment
- agent/reasoning_timeouts.py: 300s stale-timeout floor entry for
grok-4.5 (grok-4.20-reasoning entry kept for pinned users)
- docs: x-search.md en + zh-Hans (config sample + troubleshooting)
- tests: default-model assertion + timeout-floor positive case
Salvaged and rebased from #66354 by @UnathiCodex onto current main.
Fixes a fresh-chat race in Hermes Desktop where a model, reasoning-effort,
or Fast selection made before the first Send could be replaced by an
in-flight profile refresh, or read only after the profile handshake
yielded. Send is now the linearization point: the visible selector state is
snapshotted before awaiting profile readiness, and intent-generation guards
make older config/model responses stand down after a picker/toggle action.
Adds the contract-v4 session-create wire contract for explicit Fast=false.
Conflict resolution vs the original branch (use-model-controls.ts / .test.tsx):
combined main's catalog-aware keepManualPick() sticky-pick logic with the
PR's profileRefreshEpoch + composerSelectionGeneration staleness guards so
both a removed-from-catalog reseed and the in-flight-picker race are handled.
Verified on current main: apps/desktop tsc --noEmit clean; 80 affected
UI/store tests pass (use-model-controls, use-hermes-config,
use-session-actions, model-edit-submenu, model-presets, updates).

* fix(desktop): allow write-build-stamp from non-git checkouts
Stop hard-failing npm pack when neither GITHUB_SHA nor git HEAD is
available (ZIP installs / broken .git). Emit an explicit fallback stamp
instead so local Windows desktop builds can finish (#50823).
* fix(desktop): treat fallback stamps as unpinned; harden Windows install
Keep all-zero fallback commits out of -Commit/--commit pins and fetch
install.ps1 by branch instead. After bootstrap, pin the marker to the
checkout HEAD so isBootstrapComplete accepts it. On Windows, force ZIP
checkout, seed GITHUB_SHA (ASCII-only install.ps1), and avoid the pack
stamp failure.
* fix(install): pin core.autocrlf=false before ZIP-path checkout (#50823 review)
The ZIP-fallback path added in #67643 runs `git checkout -f FETCH_HEAD`
before core.autocrlf gets pinned (which only happened later, on the
shared clone-path config). On Git for Windows -- where core.autocrlf
defaults to true -- that renormalizes the repo's LF text files to CRLF in
the working tree during checkout, leaving the freshly-created managed
checkout dirty versus HEAD and aborting the next `hermes update`. That is
the exact "dirty tree the user never touched" failure the surrounding
code already guards against (install.ps1:1461-1469, 1750-1753).
Move the `config core.autocrlf false` pin to run immediately after
`git init`, before the fetch/checkout. The later idempotent pin on the
shared clone path is retained so git-clone installs are unaffected.
Addresses teknium1's review on #67643 and supersedes it, preserving the
original author's two commits.

Two real render-cost wins found by inspection (no behavior change):
1. Sidebar re-rendered on every stream token. $sessionStates is republished on
every message delta (tens/sec during a turn), and the derived ID computeds
($workingSessionIds, $attentionSessionIds, $backgroundRunningSessionIds)
allocated a fresh array each time. nanostores notifies on !==, so the whole
ChatSidebar + every mounted row re-rendered per token even when the working/
attention/background set was unchanged. Return the previous array reference
when the contents match → nanostores skips the notify unless the set actually
changes. Turns streaming from O(visible rows)/token into O(0) for the sidebar.
2. Tool rows normalized the FULL uncapped detail every render. `looksRedundant`
(lowercase + whitespace-collapse over the entire read_file/terminal payload)
ran twice in the ToolEntry render body, so every completed tool re-normalized
its whole output on every stream tick of the running message. Memoize on the
view fields so it recomputes only when the tool's content changes.
Both are correctness-preserving (stable refs + memoization). The CI stream
scenario drives $messages directly, not the publishSessionState path, so it
won't reflect #1 — verified by inspection.
Profiling the boot answered "is there a real cold-start win?": no wasteful
hotspot — the renderer does only ~tens of ms of work at mount, no heavy library
(shiki/mermaid/katex/d3/motion) initializes at startup; the rest is Electron
runtime + waiting, near the Electron floor.
It also exposed that the cold-start number was pessimistic: a fresh
--user-data-dir per run means a COLD V8 code cache and worst-case bundle
recompile every launch. Real users reuse their profile. Measured delta:
fresh (cold cache): spawn→interactive ~1.48s
reused (warm cache): ~1.0s
So representative launch is ~1.0s; only first-launch-after-install pays ~+400ms.
- coldStartSamples() reuses one profile (run 0 warms the cache, discarded;
runs 1..N are warm samples), stepping ports + pausing so the single-instance
lock releases. `--cold-fresh` measures the first-launch worst case.
- Re-baselined cold-start with the representative warm numbers.
Net: nothing high-ROI left to optimize. The only lever is shipping a pre-warmed
V8 code cache to make first launch match warm (~400ms, once per update) — real
packaging complexity for a marginal win, deliberately not pursued.
* bench(desktop): measure the full picture — prod build, cold-start, first-token
Stop drip-feeding scenarios: extend the harness to cover the latencies that
actually dominate perceived speed, and measure them on a REAL production build.
- --prod: build a production renderer with the probe included (VITE_PERF_PROBE=1,
off in normal builds) and launch it from dist/. Measures minified React, so
numbers are representative shipped figures instead of ~3x-inflated dev ones.
- cold-start scenario (tier "cold"): launch → CDP → driver → first paint, via a
fresh isolated spawn per run. Captures spawn_to_cdp_ms, spawn_to_driver_ms, fcp_ms.
- first-token scenario (backend tier): Enter → first assistant token painted —
the TTFT latency an agent app is uniquely judged on.
- run.mjs gained --prod (build once), cold-start fresh-spawn loop, and gates
ci+cold tiers against the baseline.
Baseline re-captured on a PRODUCTION build (median of 5), darwin-arm64 — all
green. Representative numbers:
cold-start spawn→interactive ~1.6s, FCP ~0.5s
stream frame p95 22ms, 1 longtask
keystroke p50 2ms, p95 8.7ms
transcript mount 145ms, 82ms longtask (400-msg open)
The prod build also settled the open question from the dev numbers: the
transcript-mount "lead" (221ms longtask in dev) is only ~72-82ms in prod — not
actionable. Measurement did its job.
* bench(desktop): trustworthy cold-start measurement (code-splitting is NOT the lever)
Investigated code-splitting the ~22MB renderer bundle to cut cold start. It is
the wrong fix on both counts:
1. Intentional design: vite.config disables codeSplitting because Shiki emits
thousands of dynamic chunks and electron-builder OOMs scanning them — a
packaging/installer constraint, not an oversight.
2. The data says it wouldn't help. Fixing the cold-start measurement to be
trustworthy and reading the boot composition (prod build):
spawn → interactive ~1.5s
renderer nav → DOMInteractive ~0.8s, → DOMContentLoaded ~1.06s
so the whole 22MB bundle EVAL is only ~0.27s (DCL − DOMInteractive) of the
~1.5s. The dominant costs are Electron/window startup and React app mount —
neither touched by splitting.
The measurement fixes (the real content of this PR — no app change, since the
optimization was rejected):
- Drop HERMES_DESKTOP_BOOT_FAKE from spawned instances — it injected artificial
per-phase boot-overlay sleeps that inflated cold-start (and slowed every run).
- Unique debug/dev port per cold-start run — a just-killed instance can hold
:9222 briefly, so reusing it made CDP attach to the DYING instance and report
garbage (spawn_to_cdp of ~4ms). Stepping the port per run fixes the race.
- Richer boot marks (dom_interactive, dom_content_loaded, main-script size) so
cold-start composition is visible, not just a single number.
- Forward all numeric boot marks from the cold-start loop.
- Re-baseline cold-start with the clean numbers.
A real cold-start win would target Electron startup / app-mount (e.g. V8 code
cache, deferred non-critical mount) — a future pass, now that it's measurable.
* fix(dashboard): make MoA presets modal opaque and readable
Card defaults to bg-background-base/80 glass, so the Mixture of Agents
dialog let the Models page bleed through — especially on Cyberpunk/mobile.
Portal an opaque dialog shell above the z-2 dashboard column, and ignore
Escape while the nested model picker is open.
* test(web): lock dashboard modal shell to opaque panel classes
Guard the MoA/dialog shell contract so glass Card defaults cannot
quietly return to modal panels, and Escape stays picker-aware.
Stop drip-feeding scenarios: extend the harness to cover the latencies that
actually dominate perceived speed, and measure them on a REAL production build.
- --prod: build a production renderer with the probe included (VITE_PERF_PROBE=1,
off in normal builds) and launch it from dist/. Measures minified React, so
numbers are representative shipped figures instead of ~3x-inflated dev ones.
- cold-start scenario (tier "cold"): launch → CDP → driver → first paint, via a
fresh isolated spawn per run. Captures spawn_to_cdp_ms, spawn_to_driver_ms, fcp_ms.
- first-token scenario (backend tier): Enter → first assistant token painted —
the TTFT latency an agent app is uniquely judged on.
- run.mjs gained --prod (build once), cold-start fresh-spawn loop, and gates
ci+cold tiers against the baseline.
Baseline re-captured on a PRODUCTION build (median of 5), darwin-arm64 — all
green. Representative numbers:
cold-start spawn→interactive ~1.6s, FCP ~0.5s
stream frame p95 22ms, 1 longtask
keystroke p50 2ms, p95 8.7ms
transcript mount 145ms, 82ms longtask (400-msg open)
The prod build also settled the open question from the dev numbers: the
transcript-mount "lead" (221ms longtask in dev) is only ~72-82ms in prod — not
actionable. Measurement did its job.
Chased the "stream frame p95 = 60ms with ZERO longtasks" mystery to its actual
cause: the default stream chunk had no paragraph breaks, so it grew into one
giant ~22KB block that re-rendered fully every flush — defeating the block
memoization real streaming relies on. Plain text = 21ms; realistic chunk with
`\n\n` breaks (blocks settle, only the tail re-renders) = 23ms. Fixed the
default chunk to model real LLM output; a break-less `--chunk` remains available
as a single-block worst-case stress.
Also hardened the isolated instance so measurements reflect real cost:
- Wait for the gateway socket to actually connect before measuring (a booting/
absent backend's reconnect backoff churns the main thread). Exposed via a new
__PERF_DRIVE__.connected() probe reading $gateway.connectionState.
- Focus emulation + anti-throttle/occlusion flags so a backgrounded perf window
isn't frame-throttled (no OS focus stealing).
- Generation-guarded the rAF frame recorder so repeated runs don't leave
overlapping recorders polluting frame intervals.
Baseline re-captured as the median of 5 --spawn runs (darwin-arm64); all three
CI scenarios now green and stable. Absolute values are dev-build (noted in
_meta) — regression guards, not shipped numbers.
Add a color picker to the session menu (an Appearance submenu of reusable
ColorSwatches, in both the dropdown and right-click flavors). The pick is a
per-session override that wins over the inherited project color; clearing
falls back to it.
Storage is desktop-local like pins ($sessionColorOverrides persistentAtom),
keyed by the DURABLE lineage id so a color survives auto-compression's id
rotation. Precedence folds into the existing $sessionColorById resolver, so
sidebar rows AND pane tabs pick it up with no changes to either — the payoff
of the shared store. To take this to the TUI later, promote this one atom to
a backend SessionInfo.color field; the resolver and picker stay put.
- sessionColorFor: drop the no-op `?? undefined` (the map read is already
string | undefined).
- sessionProjectColor: fix a now-stale doc line — a rootless (no cwd AND no
git_repo_root) row returns null, not any cwd-less row (repo-root-only rows
resolve since the grouped-but-grey fix).
- ProjectMenu.applyAppearance: await instead of a .then block; flatten the
auto-branch's nested ternary.
- Resolve the vite CLI via vite/package.json `bin` (Vite 8's exports block
importing vite/bin/vite.js directly — --spawn failed with ERR_PACKAGE_PATH_NOT_EXPORTED).
- Add a post-launch settle so cold-start contention (vite dep pre-bundling,
first backend-connect attempts) doesn't contaminate the first scenario.
- Drop the raw autolink from the default stream chunk (resolvable URLs trigger
link-embed DNS lookups unrelated to render cost).
- Replace seed baseline with real numbers from a darwin-arm64 --spawn run.
keystroke + transcript are clean; stream is a clean single-run capture (the
isolated backend may not connect, and its reconnect churn inflates frame
pacing — re-capture on a connected instance for tighter tolerances).
simple-git's custom-binary validation rejects paths containing spaces, so
the default Windows Git install (C:\Program Files\Git\cmd\git.exe) made
every Review pane git call throw and the pane silently showed 'No diffs'.
The binary is resolved inside the Electron main process from known install
locations or PATH — never renderer/user input — so for spaced paths we opt
into simple-git's supported unsafe.allowUnsafeCustomBinary escape hatch
rather than falling back to PATH (often absent in GUI-launched apps).
Simplified from PR #64713 by @unsupportedpastels; supersedes the 8.3
short-path approaches in #55337/#60156.
Fixes#54888
Kimi's Anthropic-compatible endpoints (api.moonshot.cn/anthropic,
api.kimi.com/coding) implement the adaptive thinking contract — they
accept thinking.type=adaptive + output_config.effort (all of low,
medium, high, xhigh, max verified live) and return thinking blocks, and
the replay-validation 400s that originally motivated dropping the
parameter (#13848) no longer occur.
_supports_adaptive_thinking() now returns True for Kimi-family models,
so they get thinking={type: adaptive, display: summarized} +
output_config.effort via ADAPTIVE_EFFORT_MAP instead of nothing, and
the blanket drop of the thinking parameter for Kimi-family endpoints is
removed. MiniMax and other non-adaptive third parties keep the manual
budget_tokens path; Claude behavior is unchanged.
Salvaged from #42654 by @digitalbase (earliest report of the leak, June 9):
the desktop sidebar and cron overlay showed EVERY profile's jobs because
GET /api/cron/jobs defaults to profile=all and the desktop never sent the
param — profileScoped() (landed in #67493) routes the backend process but
adds no endpoint filter on local pools.
- hermes.ts: getCronJobs(profile?) appends ?profile= when given; omitting
the arg keeps the legacy unfiltered path. profileScoped() still rides
along for process routing.
- use-session-list-actions.ts: sidebar cron refresh passes the sidebar's
profile scope (concrete profile → own jobs; ALL_PROFILES → 'all').
- app/cron/index.tsx: the cron overlay's refresh uses the same scope so
the overlay and sidebar (shared $cronJobs atom) always agree.
- Tests: list ?profile= contract in hermes-cron-scope.test.ts; sidebar
scoping in use-session-list-actions.test.tsx.
Reworked onto current main per the sweeper review: threaded through the
existing profileScoped()/list-param seams instead of the original PR's
pre-refactor call sites (DesktopController has since delegated to
use-session-list-actions).
* feat(delegation): live-viewable subagent transcripts for delegate_task
Each child now streams an append-only, human-readable log to
<hermes_home>/cache/delegation/live/<delegation_id>/task-<n>.log while it
runs, and the dispatch return includes the paths so the caller can tail
them immediately instead of waiting blind for the consolidated summary.
- New tools/delegation_live_log.py: LiveTranscriptWriter (per-event append
+ flush, one-line rendering with truncation, never raises into the agent
loop), wrap_progress_callback (tees the child's existing
tool_progress_callback events into the log, preserves the _flush
contract), dispatch-time creation with pre-headered files so tail -f
attaches immediately, manifest.json (goals/task count/per-task status),
and 7-day retention pruning on new dispatches.
- delegate_task: wraps each child's progress callback with the writer;
sync results and background dispatch responses gain live_transcripts
(+ hint field on dispatch); per-task result entries carry
live_transcript; transcripts finalized with exit-reason markers.
- async_delegation: dispatch_async_delegation_batch accepts an optional
delegation_id so the live/ dir name matches the returned handle; the
completion event carries live_transcripts.
- process_registry: consolidated batch-completion block references each
task's live transcript path.
- Tool schema description documents the live_transcripts return surface;
docs gain a 'Live Transcripts' section with a tail -f example.
Placement under cache/delegation means the logs are mounted read-only
into remote terminal backends for free. Side-channel only: zero changes
to message content, so prompt caching is unaffected. Transcript-OUT only
— no overlap with the subagent control surfaces of PR #66046.
* fix(delegation): label the kickoff transcript line as user — it is the child's one user message
