docs(edge): check the local Vercel bundle with /readyz, not /healthz - #708
Merged

Conversation
PR #694 made /healthz pure process liveness and added /readyz, which lands after the "Run the Vercel bundle locally" recipe this page gained in #698. The recipe therefore verified nothing: /healthz never builds the request's stores, so it answers 200 whether or not DATABASE_URL resolves, and the whole point of that section is proving the pg fallback reached a local Postgres with no WebSocket proxy. Verified against a real local Postgres on a bundle built from main: /healthz answers 200 with a database that is not there, /readyz answers 200 naming the three probed stores when it is, and 503 naming ECONNREFUSED when it is not. The two sample bodies are that run's output, and the password in the failing connection string does not appear in the response. Also adds /readyz to the rooted surfaces the runtime owns.

Neither change affects this page. #705 batches route-discovery errors, and #708 is the edge page's own local-run recipe switching from /healthz to /readyz for the same reason this guide already did. #691 was closed unmerged, so the emitted function directory is still index.func and this page's shadowing argument stands unchanged. Only the lastmod manifest conflicted; regenerated. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The "Run the Vercel bundle locally" recipe added in #698 verified nothing, because #694 landed after it.
#694 made
GET /healthzpure process liveness and addedGET /readyz. The recipe still called/healthz, which never builds the request's stores, so it answers200whether or notDATABASE_URLresolves. That is the opposite of what the section is for: it exists to prove the newpgfallback reached a plain local Postgres with no WebSocket proxy.Verified, not assumed
Built a Vercel fixture from current main and ran both endpoints against a real local Postgres container:
/healthz200 {"status":"ready"}200 {"status":"ready"}/readyz200, three storesok503 not_ready, namesECONNREFUSEDThe two sample bodies in the diff are that run's actual output. I also ran the documented command verbatim, and confirmed the password in a failing connection string does not appear in the response body, which is what the redaction claim rests on.
/readyzpassing is also an end-to-end confirmation of #698 itself: the checkpointer, threads store, and permissions store all answered over a pooledpgTCP connection to a non-Neon host, with no proxy anywhere.Also
Adds
/readyzto the rooted surfaces the runtime owns, two paragraphs above. That list was written before #694 and did not mention it.Checks
check-docs.mjs, the docs snippet and docs bundle suites, the web SEO and docs component suites, andpnpm lintall pass. The SEO lastmod manifest is regenerated; only the edge route moves.This touches no file that PR #700 touches.
