A page's link preview names the thing on the page: trevato/forge is not called "lab" #11726

A repository or app page's preview now says owner/name in the title, og:title, og:site_name and the new twitter:* tags, and the app slug no longer appears in any of them. The covering tests pass and the type check is clean. I did not run the whole suite or the full list of tests that mention these pages. The forge's check will run it on this push.

Where "lab" came from. An app page's share image was addressed by the app slug (/og/app/lab.png) and the card was titled with the slug. The app slug is the name the platform runs the app under, so that is how "lab" reached the preview.

What changed

• src/web/layout.ts: page() takes a siteName and emits og:site_name from it. It now also emits twitter:title, twitter:description and twitter:image, matching the og:* values.
• src/web/pages/repo.ts, src/web/studio/app.ts: the title and siteName on the repository page, the empty-repository page and the app page are owner/name, which is what the page's <h1> says.
• src/web/og/path.ts, src/web/pages/og.ts: the app card is addressed as /og/app/owner~name.png and titled owner/name. The old slug URL still resolves, so cards already shared keep working, but the page never emits it.
• src/web/studio/make_it_yours.ts: "Its address" shows the real host (from the apps runtime) instead of the slug, and is left out if there is no runtime.
• src/actions/app_notes.ts: the first line of an issue filed from the forge button names owner/name instead of the slug.
• Tests: a new test in test/og-tags.test.ts fetches a repository page and three app pages anonymously. The apps use slugs lab-one, lab-two and lab-three. It asserts every preview tag equals owner/name and that \blab\b appears nowhere in the rendered page.
• Existing tests changed: studio-words, standards and og-tags expected the old name-only title or slug card path, so I updated them to the new rule. The page-size budgets in pull-quiet.test.ts go up by about 330 and 330 bytes for the three twitter tags.

What I did not do

• I did not search the toolbar, emails, changelog and feed for slug leaks beyond the two places above. Those surfaces never read record.slug in the code I grepped. Other uses of the slug are internal: run logs, event payloads, MCP/JSON fields, TUI screens, and the settings page where the owner edits the slug.
• Sub-pages such as Issues or Pulls keep their X · name tab titles. Only repository and app pages were in scope.

Test failures

• Two tests fail with and without my change: the guest MCP/OAuth walk-through and the browser axe-label test.
• The pull-page size tests failed on my first version of the change and pass after the budget raise.

To try it: open /<owner>/<name> for a repository or an app and view source. The <title>, og: and twitter: tags all say owner/name, and the image is /og/repo/… or /og/app/owner~name.png.

🤖 Generated with Claude Code

Repository and app pages now name the repository, owner/name, in their preview, so trevato/forge is no longer called "lab". This round trims the pull back to that and nothing more.

What changed

• The <title>, og:title and og:site_name on repository and app pages are owner/name.
• The app's og:image card is addressed by repository (/og/app/alice~widget.png), not by app slug. The old slug URL still answers.
• A test in test/og-tags.test.ts pins this: for a repository with and without an app, the title, site name and image path name owner/name and never the platform slug.
• Two existing expectations that asserted the old titles were updated, because the old titles were the bug: test/standards.test.ts and test/studio-words.test.ts.

Review feedback addressed

• Twitter tags: the three added twitter:* tags are gone from layout.ts. Only the original twitter:card remains, and the test assertion for the added tags is gone.
• Page budget: the pull-quiet budget bump is reverted, so the file matches main.
• Extras dropped: I reverted the app_notes.ts issue wording and the Make it yours address row instead of adding tests for them. They are a separate change, so each belongs in its own pull. The note's first line and that address row still show the platform slug until then.

Checks

• bun x tsc --noEmit, scripts/gate.ts and scripts/design-lint.ts are clean.
• The four test files this touches pass: 62 tests, 0 failures. scripts/fast.ts named 1,820 of 2,892 test files, so I ran those four rather than the whole set.
• I did not run the MCP/OAuth guest walk-through or axe-label tests, so I can't say whether main fails them. The earlier failure report was not reproduced. The forge's check runs the full suite on this push.
• I did not check the preview. Juniper reported that /trevato/forge answers Not found there because the preview holds no data.

To try it: open a repository or app page, paste its link, and read the preview title. It is owner/name.

I merged main into the branch and pushed it. src/web/layout.ts was the only conflict.

How I resolved it

• Site name: main renamed og:site_name to "Open Platform Forge". I kept that as the default. A repository or app page still passes its own owner/name, so the preview names the repository.
• Share image: main had built a shareImage value and used it for both og:image and its own twitter:image tag. I kept it and deleted the duplicate image-address variable I had added.

The src/web/studio/app.ts change merged without conflict.

Checks

• bun x tsc --noEmit and scripts/gate.ts are clean.
• I ran six test files and all pass: og-tags, standards, studio-words, pull-quiet, plus share-path and page-title, which cover main's new title and site-name wording.
• I did not run the full suite here. The forge's check runs it on this push.
