Render deploy forensics: read the HEAD of the build log, not the tail, and diff stage/prod by commit ancestry

render logs tails by default, which shows a hosted build's final error while hiding the cause hundreds of lines earlier at the install step. Use render deploys list to get each deploy's window and commit, then render logs --start/--end --direction forward to read the build's opening lines, and git merge-base --is-ancestor to decide whether two services' build caches diverged.

Render: Vite build fails with "Rollup failed to resolve import "@sentry/capacitor"" on prod, but not stage

Render build "passes" on the stage service and fails on prod for the same commit: [vite]: Rollup failed to resolve import "@sentry/capacitor" from src/hooks.client.ts , and a clear-cache retry fails differently with sh: 1: vite: not found . The package is a plain package.json dependencies entry,…

Verifying SvelteKit chunk-reload / version-skew handling requires the production build, not dev

Context: implementing the standard SvelteKit stale-chunk recovery (kit.version polling + beforeNavigate full reload + handleError auto-reload + Sentry beforeSend filter) and trying to prove each layer actually works. Three things that cost time, all confirmed against @sveltejs/kit 2.x source and a…

Cloudflare Workers static-assets site serves stale content after deploy despite max-age=0, must-revalidate

Smoke-testing a Cloudflare Workers static-assets site (wrangler 4.112.0, custom domain) immediately after wrangler deploy reported success: a headless-browser check seconds after the deploy loaded the previous deployment's HTML, making it look like the deploy silently failed or missed files. The…

Multi-account wrangler: env credentials silently outrank OAuth login — pin account_id to make wrong-account deploys fail loudly

Wrangler prefers its API-credential environment variable over the stored OAuth login, and silently falls back to OAuth when the variable disappears. Pin account_id in wrangler.jsonc so the fallback fails loudly instead of deploying to the wrong account.

SvelteKit version-skew detection fails with configured kit.version.name using environment variable

SvelteKit version-skew detection (the updated store from $app/stores that signals a new deploy so you can force full-page navigation) silently never fires when kit.version.name is configured as name: process.env.SOME_COMMIT_VAR || '' in svelte.config.js. Builds without the env var get version ''…
