Subject: [PATCH] perf(bundle): stop three routes shipping the block and tool
 registries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The public /integrations page downloaded, parsed and executed 19.54 MB of
JavaScript, 15.52 MB of which was the tool registry — 4,351 tool configs, to
render a catalog of names and icons. It arrived as `<script async>` in the
initial HTML, so the browser fetched and ran it on load.

Measured on a production build, chunks referenced by the page's own HTML:

  /integrations   19.54 MB -> 3.55 MB across 41 chunks   (-82%)

No chunk over 1 MB remains on that route. credit-usage also loses its copy.

Three separate import edges, all the same shape: a module mixing pure helpers
with registry-backed ones, so importing the pure half dragged in all 282 block
configs and the tool registry behind them.

- `lib/integrations/index.ts` built POPULAR_WORKFLOWS at module scope via
  `getAllBlockMeta()` and re-exported registry functions. The landing grid is a
  client component, so importing anything from that barrel inherited the whole
  graph. POPULAR_WORKFLOWS moves to its own module — its one real consumer is a
  server page — and the re-export goes, which .claude/rules/sim-imports.md
  already forbids and which nothing imported through the barrel.

- `blocks/icon-color.ts` mixed pure contrast maths (`getTileIconColorClass`,
  `isLightTileColor`, used by the landing page) with `getBareIconStyle`, which
  reads `getAllBlocks()`. Split by dependency into `blocks/brand-icon-style.ts`;
  all six of its consumers are under app/workspace/** where the registry is
  already legitimately present.

- `credit-usage-view.tsx` imported a date formatter from the logs feature's
  `utils.ts`, which also exports registry-backed badge components.
  `formatDateShort` has three consumers across three features, so it moves to
  `lib/core/utils/date-display.ts` per the repo's utils-location rule.

Not addressed: account/settings/[section] still reaches the registry through
workspace-permissions-provider -> socket-provider, one of the four known
client edges from the module-graph audit rather than a stray import. It is
also loaded via `dynamic()`, so it is likely lazy rather than on first paint.
That belongs with the registry split, not here.

workspace/* keeps its copy, which is correct — the editor needs tool params
and outputs.

+ * `blocks/registry-maps` → all 282 block configs → the tool registry, and any
+ * client component importing *anything* from the barrel inherited the whole
+ * graph. The landing `/integrations` grid is a client component, so a public
+ * marketing page was shipping the full registry to render a catalog of names
+ * and icons.
+ *
+ * Keeping it in its own module means the one server component that needs it
+ * imports it directly, and the barrel stays free of `@/blocks` value imports.
