Quick start

Greenfield UI Kernel profiler — UI Kernel + ux-blocks shell chrome; role CSS from ux-blocks tiers.

Install

composer require symfinity/ui-profiler --dev

Flex recipe symfinity/ui-profiler 0.1 registers UiProfilerBundle for dev/test and copies config/packages/symfinity_ui_profiler.yaml.

Requires symfinity/ui-kernel, symfinity/ux-blocks-core, and symfinity/ux-blocks-extended (see installation).

URL / action	Check
`/`	WDT visible; Chameleon-themed chrome (no legacy Symfony yellow toolbar)
`/kernel`	WDT + theme badge
WDT → profiler	Shell two-column; sidebar collectors use kernel tokens
`?panel=time`	Timeline readable; styles from SCSS author pipeline
`?panel=ui_kernel`	UI Kernel theme/CSS panel
Settings dialog	Theme + width toggles
`/` key	Focus search in panel when open

Use the WDT token from the page you profiled — /_profiler/latest may point at an asset request.

Key	Action
`/`	Focus first table search field (when not in an input)
`Esc`	Close settings `<dialog>`

From the package directory:

composer test
# or focused parity subset:
vendor/bin/phpunit -c phpunit.xml.dist --group ui-profiler-parity

Symptom	Fix
Toolbar layout jump	Inline WDT skeleton in `toolbar_js.html.twig`; no external WDT CSS
Single-column profiler shell	Hard refresh; shell embeds grid CSS
System theme wrong	`scheme=auto` uses client `prefers-color-scheme`; cookie `symfinity_ui_kernel_scheme`
Width toggle no effect	Clear `localStorage['symfony/profiler/width']`; expect `width-normal` vs `width-full`
Unstyled third-party panel	Expected for unmigrated `sf-*` collector markup — see Third-party collectors
Owned CSS uses legacy `.sf-*` selectors	Run package PHPUnit — owned shell CSS must not reintroduce Symfony toolbar class vocabulary
Broken AssetMapper assets in dev	Delete `public/assets/` if you ran `asset-map:compile` and live CSS stops updating
CssBudgetTest fails (forks)	Remove owned `.css` — use ux-blocks + PHP-embedded shell chrome only
