feat(api): page.publicPull returns a public page's stored HTML - #9652
Readers outside a page's organization can open an "Anyone with the link" page, but the only
public read, page.publicView, returns the viewer address. The usercontent worker rewrites HTML
on that path: it injects the theme style and the storage, tools and runtime scripts. So a CLI
that pulls from there gets a different document from a member's page.pull, and republishing it
injects the runtime a second time (injectScriptTag does not check for an existing tag).
page.publicPull({ slug }) applies the same checks as publicView: visibility "everyone", not
taken down, served version only. It returns a presigned URL to the stored bytes, as page.pull
does for members, or null when the page is not public.
publicView now shares that lookup. Its output is unchanged, and the visibility check still runs
before the version query, so its cost for non-public pages is the same.
Compatibility: a new public procedure only. No existing input, output, error code or behaviour
changes. The CLI change that calls it is #9651, which merges after this is deployed.
How I tested it
New unit tests for the public check (visibility and takedown) in shared-version.test.ts.
The test was written first and failed, then the helper was added.
bun test in packages/trpc: 899 pass. Typecheck and biome are clean.
Not run: a call against a running API. The database path matches page.pull's (version row,
then presignedGetUrl(storageKey)).

New Features
Public pages now offer a download option with details for the version currently being served.
Bug Fixes
Public page views are limited to pages that are publicly available and have a served version. Pages that are private or taken down are not shown as public.
`page.publicView` gives readers outside a page's organization only the
viewer address, and the usercontent worker rewrites HTML on that path:
it injects the theme style and the storage, tools and runtime scripts.
A CLI that pulls from there gets a different document than a member's
`page.pull`, and republishing it injects the runtime a second time.
`page.publicPull({ slug })` applies the same checks as `publicView`
(visibility "everyone", not taken down, served version only) and
returns a presigned URL to the stored bytes, as `page.pull` does for
members. It is a new public procedure; nothing existing changes shape.
The page router now shares public-page lookup between publicView and a new publicPull query. Public eligibility checks visibility and takedown status. The pull query returns served-version metadata and a presigned download URL when available.
isPubliclyServed checks that visibility is everyone and the page is not taken down. Tests cover public, organization-only, owner-only, and taken-down pages.
Public lookup and pull packages/trpc/src/router/page/page.ts
loadPublicPage returns a page and served version only when the page is publicly served and has a served version. publicView uses this helper. publicPull returns null when lookup or version-row matching fails, and returns metadata with a presigned URL otherwise. Presigning failures are logged and returned as a NOT_FOUND user error.

ParadevAI/Paradev#9651: The CLI changes use the publicView procedure, whose public-page lookup this PR refactors.
The new public pull endpoint hands out download links that keep working for up to an hour after a page is taken down or made private. Shorten the link lifetime before merging, or accept that window explicitly. The rest of the change preserves the existing public view behavior.

Explanation
The title "feat(api): page.publicPull returns a public page's stored HTML" follows conventional commit format and names the main change: a new public procedure that returns the stored HTML of a public page. The diff adds pageRouter.publicPull, which returns a presigned URL to the served version, and adds isPubliclyServed to shared-version.ts. The title describes the procedure as returning HTML, while the code returns a presigned URL to the stored bytes. This is a minor wording mismatch, not an unrelated title.
Full details: Description check
Explanation
The description covers the 'What & why' section with the problem (the publicView output is rewritten by the usercontent worker), the solution (publicPull with the same checks as publicView), and compatibility notes. The 'How I tested it' section lists unit tests, the bun test run, typecheck and biome results, and a note that an API call was not run. It does not link an issue, and it includes no screenshots. The checklist from the template is absent, so the PR title convention, lint/typecheck, maintainer-edit, and CLA items are not confirmed. The description is mostly complete.

publicPull returns a presigned storage URL for the stored HTML. The URL is valid until it expires, and the storage layer does not check page visibility or takedown state. With the default one-hour lifetime, a URL issued before a page is made private or taken down stays downloadable for up to an hour. Takedown removes only the manifest that the Worker checks, and publicView remains gated by the manifest.
Set a shorter lifetime for this route. The window then equals the new lifetime, which narrows the exposure but does not remove it. Confirm that the consumer downloads the URL promptly before choosing the value.

Verdict: minor issues. The approach is right and the change is additive only, so it is safe for released clients. One change is worth making before merge.
minorpackages/trpc/src/router/page/page.ts:1355: presignedGetUrl uses its 1 h default on an unauthenticated endpoint, so a URL minted before a takedown or a visibility flip keeps working for up to an hour. Pass a short expiry, for example presignedGetUrl(row.storageKey, 60).
nitpackages/trpc/src/router/page/page.ts:1341-1367: the version-row lookup and the presign block are copied from pull (page.ts:1243-1274). Extract a shared helper.
nitpackages/trpc/src/router/page/shared-version.test.ts:44: only the predicate is tested, not the procedure itself.
Verified at 449c7068: an anonymous page.publicPull against a local Postgres returns null for org, taken-down and unknown pages, and for a public page it returns the served (or pinned) version with a URL to the stored bytes. publicView output is unchanged. Unit tests (899 pass), typecheck and biome are clean, and CI is green.
Andrew follow-up failed: superset workspaces share add --user satya@superset.sh failed with "A cloud workspace cannot call cloudWorkspace.sharing.add. Run this from a client you are signed into." (tried twice). The tag and the #ext-andrew post succeeded.
I suggest closing this in favor of the API direction in my review on #9651.
With that change, page.pull returns the stored HTML of the served version to signed-in readers outside the page's organization, so publicPull has no remaining caller. publicView stays the only unauthenticated read. If signed-out pages pull is needed later, I'd add a download link to publicView rather than a second public procedure. A new public procedure would also need a short URL expiry and a rate limit: the presigned URL here is valid for 1 hour and cannot be revoked by a takedown.
Parts worth keeping: the served-version check in loadPublicPage / isPubliclyServed fits as the non-member branch of the new read loader on #9651.
