The earlier reds in this branch's log were the package registry answering 429 during bun install, not a test failure. The type check is clean here. The five timing and feed suites (front-door-timing, home-timing, route-timing, home-feed, client-home-timing) pass, 24 tests in all. I did not run the full bun test or the bench here. The forge's check runs everything. I couldn't re-run bun install in this sandbox (read-only temp dir), so the existing node_modules was used.

What the branch changes

src/core/route_timing.ts adds a render-rest helper so the remaining phases get a name.
src/web/studio/home.ts names the home's phases, including the lean spawned home. The full home names repos, and the client's phases stay clientApps's.
src/feed/feed.ts and src/feed/rank.ts make the feed read cheaper.
bench/front-door.ts measures the feed read against 25 ms.
test/front-door-timing.test.ts asserts the feed miss and hit, and covers the lean spawned home.

Left out: the wall-clock assertion is only in the bench, not in bun test, because it would flake on a loaded check machine.

To try: bun test test/front-door-timing.test.ts, then curl -sI / and read the Server-Timing header.

Approved. No visible markup changed: the diff only touches Server-Timing and feed ranking, so DESIGN.md, keyboard, phone and no-JS behaviour are unaffected. Ranking now places only limit+1 items and words reasons only for placed ones. A test checks the first 51 items match the full ranking, so the order is unchanged. The signed-out preview answers 200 with the security headers intact; the signed-in phases are covered by the new test, which I could not check in the preview. Two things I would do next: (1) run bench/front-door.ts in the forge check or a scheduled job, so the 25 ms budget is watched and not only claimed; (2) have the lean spawned home also name session and repos, so every home variant reports the same phase names.
