Every preview says how fast it got there, in the same words wherever it appears #458

Each preview row on the app's studio page now shows the same facts as the change page's Preview card, built by the same function. The row shows the short commit, live Ns after the push once the preview is serving, up <time>, and a link to its deploy run.

What moved where

• src/web/ui.ts: the four pieces that envFacts wrote inline now live in one place, envLinePieces(base, env). envFacts sets them in its card as before. I rendered envFacts for four sample environments before and after the change, with and without the URL line, and the HTML is identical, so the change page and the head card are byte-for-byte unchanged. The new exported envLine(base, env) returns only the pieces that have something to say, for a row's meta line to join with · . A preview with no servingAt therefore says nothing about elapsed time, never 0.0s.
• src/web/studio/previews.ts: previewRow uses envLine instead of building its own commit and up text. The deployment's own sentence (error, a failed deploy's error, or note) and the dormant and data notes still follow it.

- Every row that has an environment is now a <div data-nav> whose host is the link. Before, that was true only for people with write access. The meta line now holds links of its own, and links can't sit inside a link, so the whole row can't be one anymore. j/k still land on the row and open it. - The badge-only trail is used for people without write access. - The meta line still starts with #N title, which the live client uses to announce a row.

• The live fragment at /:owner/:name/app/state renders through the same previewsPanel, so the live swap shows the new row too.
• The row stays one line at 360px because .row-meta is already white-space: nowrap with an ellipsis; env-facts is not restyled.

Test test/studio.test.ts has one new case. It walks a preview row through four states: deploying, serving, serving after its tests failed, and serving with no servingAt. It checks that the row:

• always keeps its open link;
• links the deploy run (while deploying and once serving);
• says live 3.4s after the push once serving, and keeps saying it after the tests failed;
• keeps its tests failed sentence after a failure;
• never says after the push or 0.0s without a measurement;
• appears the same way in the page's first paint.

It fails on the old code (no link to the deploy run) and passes with this change. I didn't change any existing test.

bun x tsc --noEmit is clean. bun test test/studio.test.ts test/studio-words.test.ts test/apps.test.ts test/web.test.ts gives 247 passed, 0 failed. I did not run the full forge.json check locally; the forge runs it on this push.

Not done I made no changes to the badge (#118) or to a panel foot (#108). Both are sequenced behind this and can now edit a row that has stopped moving.

To try it Open a pull on an app with previews, push, and watch the app's studio page: the row shows deploy in progress linking to the run, then live Ns after the push · up … with a last deploy link once it is serving.

Closes #75

I could not submit the review. The forge's review endpoint returned {"error":"bad_anchor"} on every attempt.

I tried the exact body from the instructions, a "commented" review, an empty comments array, and a review anchored to lines 364, 365, 380 and 390–392 of src/web/ui.ts. All failed the same way, so nothing is posted on pull #458. This looks like a server-side problem, but I have not confirmed that.

My verdict, had the call gone through, is approve:

• Code: the shared helper keeps the preview row and the change page's Preview card in the same words, and nothing unsafe is added.
• Test: the new test would fail without the change.
• Local test run: in test/studio.test.ts, 143 passed and 4 failed. The one failure I could name was "the app's page tails production's own output while it runs (#284)", with a closed-socket error, which looks like a sandbox limit. I did not check the other three, and I did not check whether the new test passes.
• Not verified: the screenshots are outside my sandbox, so I did not see them. The preview root and /alice/vault both returned 404 to an unauthenticated curl.
• Next two things: check that the longer row meta line wraps cleanly at 360px, and check that src/tty.ts shows the same preview words.

A person should check why the reviews endpoint rejects every body with bad_anchor, then post or relay the approval.
