## Summary
Implements server-side remote configuration to decouple runtime behavior
from build artifacts, enabling dynamic configuration updates without
redeployment.
## Technical Changes
- **Replaced** build-time constants (`__MIXPANEL_TOKEN__`,
`__BUILD_FLAGS__`) with runtime configuration loaded from
`/api/features`
- Configuration now sourced from `window.__CONFIG__` (hydrated from
`/api/features` endpoint)
- **Added** `src/platform/remoteConfig/` service that polls server
configuration every 30 seconds
- **Modified** application bootstrap sequence in `main.ts` to load
remote config before module initialization (required for cloud builds)
- **Removed** global constants: `__BUILD_FLAGS__`, `__MIXPANEL_TOKEN__`.
Runtime subscription enforcement toggle via `subscription_required` flag
- Server health alerts with variant-based severity rendering
(info/warning/error) via topbar badges
## Rationale
- **Build-once-deploy-anywhere**: Single immutable artifact promoted
through environments (staging → production)
- **Zero-downtime configuration**: Update behavior without rebuilding or
redeploying the application
- **Incident response**: Disable features or display alerts dynamically
in response to outages or degraded service
- **Instant rollback**: Revert configuration changes server-side without
artifact redeployment
- **Progressive delivery**: Enable A/B testing, canary releases, and
user/region-based configuration
- **Environment parity**: Eliminate configuration drift between staging
and production builds
- Decouples deployment cadence from configuration changes
- Enables GitOps workflows for configuration management separate from
code deployments
- Supports real-time operational control of client behavior
- Reduces build matrix complexity (no per-environment builds)

When a widget is linked to a subgraph, the subgraph creates a copy of
the widget. The callback used by the asset browser to update the widget
still refers to the widget that lives inside the subgraph, but at time
of execution, this is overwritten by the unchanged value of the copy.
This is fixed by instead updating the value of the caller. It's a little
hacky, and may need future review.

## Summary
Enables Vue nodes to resize from all four corners and consolidated the
interaction pipeline.
## Changes
- **What**: Added four-corner handles to `LGraphNode`, wired them
through the refactored `useNodeResize` composable, and centralized the
math/preset helpers under `interactions/resize/` with cleaner pure
functions and lint-compliant markup.
## Review Focus
Corner-to-corner resizing accuracy (position + size), pinned-node guard
preventing resize start, and snap-to-grid behavior at varied zoom
levels.

## Summary
Centralized all download functionalities across app. Then changed
downloadFile on the cloud distribution to stream assets via blob fetches
while desktop/local retains direct anchor downloads. This fixes issue
where trying to download cross-origin resources opens them in the
window, potentially losing the user's unsaved changes.
## Changes
- **What**: Moved `downloadBlob` into `downloadUtil`, routed all callers
(3D exporter, recording manager, node template export, workflow/palette
export, Litegraph save, ~~`useDownload` consumers~~) through shared
helpers, and changed `downloadFile` to `fetch` first when `isCloud` so
cross-origin URLs download reliably
- `useDownload` is the exception since we simply cannot do model
downloads through blob (forcing user to transfer the entire model data
twice is bad). Fortunately on cloud, the user doesn't need to download
models locally anyway.

## Summary
Fix hover state on Vue node number widget incremenet/decrement buttons.
The problem was in `useNumberWidgetButtonPt.ts`, the button hover styles
were using `var(--color-node-component-surface-hovered)` which
references a Tailwind theme color created by the `@theme` inline
directive. This theme color doesn't properly inherit the `.dark-theme`
class overrides, so it was showing the light mode color (white) even in
dark mode.

`Comfy.Canvas.NavigationMode` and `Comfy.Canvas.LeftMouseClickBehavior`
introduce a circular dependency where setting the value of one will set
the value of the other.
This is solved by having `NavigationMode` skip changing other settings
when `oldValue` is undefined.
- Note that `oldValue` is only undefined during initial load. When a
user changes the value for the first time, oldValue will be the default
value.
In the unlikely event desync occurs (a user manually editing the backing
json?), the registration of the subsequent `LeftMouseClickBehavior` will
still correct `NavigationMode` back to custom

Some virtual nodes (like get/set nodes) perform link redirection at
prompt resolution. The prior implementation incorrectly tried to return
the source of the virtual link after resolution, but this causes things
to break when the source of the virtual link is a subgraph IO.
Instead, this PR changes the code section to restart resolution from the
destination of the virtual link so that the existing subgraph boundary
resolution code is applied.
Also fix a bug with reconnection of complex/any types on
conversion to subgraph.

## Summary
- Fixed issue where enabling a disabled pack incorrectly triggered
installation instead of using the dedicated enable endpoint
- Added proper `enablePack` method in the manager service layer
- Updated store and component to use the correct API call
## Problem
When users toggled a disabled pack to enable it via `PackEnableToggle`
component, the system was incorrectly calling the install endpoint with
full installation parameters instead of the simpler enable endpoint that
only requires the pack ID.
## Solution
1. **Added dedicated `enablePack` method in `comfyManagerService.ts`**:
- Uses the `'enable'` task kind with `EnablePackParams`
- Only requires `cnr_id` parameter (simpler than install)
2. **Updated `comfyManagerStore.ts`**:
- Created proper `enablePack` function that queues an enable task
- Removed the incorrect aliasing where `enablePack` was pointing to
`installPack`
3. **Simplified `PackEnableToggle.vue`**:
- Now calls `enablePack` with only required parameters (id, version)
- Removed unnecessary installation-specific parameters
## Test plan
- [x] Enable a disabled pack and verify it uses the enable endpoint (not
install)
- [x] Confirm the pack is properly enabled after the operation
- [x] Check that the task queue shows "Enabling" message (not
"Installing")
- [x] Verify existing install/uninstall functionality still works
Fixes#6154

## Summary
Added Service Worker to inject Firebase auth headers into browser-native
`/api/view` requests (img, video, audio tags) for cloud distribution.
## Changes
- **What**: Implemented [Service
Worker](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API)
to intercept and authenticate media requests that cannot natively send
custom headers
- **Dependencies**: None (uses native Service Worker API)
## Implementation Details
**Tree-shaking**: Uses compile-time `isCloud` constant - completely
removed from localhost/desktop builds (verified via bundle analysis).
Verify yourself by building the app and `grep -r
"registerAuthServiceWorker\|setupAuth" dist/`
**Caching**: 50-minute auth header cache with automatic invalidation on
login/logout to prevent redundant token fetches.
**Message Flow**:
```mermaid
sequenceDiagram
participant IMG as Browser
participant SW as Service Worker
participant MT as Main Thread
participant FB as Firebase Auth
IMG->>SW: GET /api/view/image.png
SW->>SW: Check cache (50min TTL)
alt Cache miss
SW->>MT: REQUEST_AUTH_HEADER
MT->>FB: getAuthHeader()
FB-->>MT: Bearer token
MT-->>SW: AUTH_HEADER_RESPONSE
SW->>SW: Cache token
end
SW->>IMG: Fetch with Authorization header
Note over SW,MT: On login/logout: INVALIDATE_AUTH_HEADER
```
## Review Focus
- **Same-origin mode**: Service Worker uses `mode: 'same-origin'` to
allow custom headers (browser-native requests default to `no-cors` which
strips headers)
- **Request deduplication**: Prevents concurrent auth header requests
from timing out
- **Build verification**: Confirm `register-*.js` absent in localhost
builds, present (~3.2KB) in cloud builds

## Summary
This code is entirely excluded from open-source, local, and desktop
builds. During minification and dead-code elimination, the Mixpanel
library is fully tree-shaken -- meaning no telemetry code is ever
included or downloaded in those builds. Even the inline callsites are
removed during the build (because `isCloud` becomes false and the entire
block becomes dead code and is removed). The code not only has no
effect, is not even distributed in the first place. We’ve gone to great
lengths to ensure this behavior.
Verification proof:

Telemetry is *enabled only in the ComfyUI Cloud environment*. Its goal
is to help us understand and improve onboarding and new-user adoption.
ComfyUI aims to be accessible to everyone, but we know the learning
curve can be steep. Anonymous usage insights will help us identify where
users struggle and guide us toward making the experience more intuitive
and welcoming.

## Summary
This PR reverts #5922 which fixed pointer capture behavior on video and
image preview components to prevent unintended node dragging.
## Changes
- Removes `data-capture-node="true"` attribute from `VideoPreview.vue`
and `ImagePreview.vue` components
- Removes pointer event delegation logic from
`useNodePointerInteractions.ts` composable
- Restores previous drag behavior where dragging on preview components
triggers node drag
## Reason for Revert
This changes the behavior from original Litegraph and is generally
annoying. Users would rather be able to drag the node than be able to
drag an image/video out from a node.
Reverts #5922

## Summary
- Implement dynamic imports for internationalization (i18n) locale files
to reduce initial bundle size
- Only load English locale eagerly as default/fallback, load other
locales on-demand
- Apply code splitting to both main ComfyUI frontend and desktop-ui
applications
## Technical Details
- **Before**: All locale files (main.json, nodeDefs.json, commands.json,
settings.json) for all 9 languages were bundled in the initial
JavaScript bundle
- **After**: Only English locale files are included in initial bundle,
other locales are loaded dynamically when needed
- Implemented `loadLocale()` function that uses dynamic imports with
`Promise.all()` for efficient parallel loading
- Added locale tracking with `loadedLocales` Set to prevent duplicate
loading
- Updated both `src/i18n.ts` and `apps/desktop-ui/src/i18n.ts` with
consistent implementation
## Bundle Size Impact
This change significantly reduces the initial bundle size by removing ~8
languages worth of JSON locale data from the main bundle. Locale files
are now loaded on-demand only when users switch languages.
## Implementation
- Uses dynamic imports: `import('./locales/[locale]/[file].json')`
- Maintains backward compatibility with existing locale switching
mechanism
- Graceful error handling for unsupported locales
- No breaking changes to the public API
## Test plan
- [x] Verify initial load only includes English locale
- [x] Test dynamic locale loading when switching languages in settings
- [x] Confirm fallback behavior for unsupported locales
- [x] Validate both web and desktop-ui applications work correctly
