<observations> Date: Jul 30, 2026 * 🟡 (19:15) Agent ran `pnpm install` in binpatch/website. Added sharp@0.35.3. Warning: esbuild@0.28.1 build scripts ignored (need `pnpm approve-builds`). Install completed in 5.4s with pnpm v10.28.0. * 🟡 (19:15) Agent designed mermaid flowchart diagram for binpatch index.mdx "How an update flows" section. Diagram nodes: CI (old + new binary) → bsdiff+zstd → Patch (TRDIFF10) → publish → GHCR/GitHub Releases → discover → Updater → download chain (parallel) → apply + SHA-256 verify → Verified new binary. * 🟡 (19:15) Agent restored "The catch" and "How an update flows" sections to binpatch/website/src/content/docs/index.mdx (positioned between "When to reach for binpatch" Tabs and "## Get started"). * 🟡 (19:15) Agent encountered build failure: `rollupOptions.input should not be an html file when building for SSR. Please specify a dedicated SSR entry.` Error originates in vite@7.3.6 at config.js:33532 (resolveRollupOptions function). Triggered when SSR build resolves input to default `index.html` fallback. Stack trace: astro@7.1.6 → static-build.js:68 → viteBuild. * 🟡 (19:16) Agent investigated mermaid package: no HTML files exist in /home/byk/Code/binpatch/website/node_modules/mermaid/. Package.json exports: `{".": {"types": "./dist/mermaid.d.ts", "import": "./dist/mermaid.core.mjs", "default": "./dist/mermaid.core.mjs"}, "./*": "./*"}`. main is `None`, module is `./dist/mermaid.core.mjs`. * 🟡 (19:16) Agent tried first fix: added `vite: { ssr: { external: ['mermaid'] } }` config to astro.config.mjs — still fails with same error. * 🟡 (19:17) Agent traced error to vite@7.3.6 config.js:33532 — code path: `if (ssr && typeof input === "string" && input.endsWith(".html")) throw new Error(...)`. Input becomes `resolve$4("index.html")` when libOptions is unset. Default `index.html` fallback at project root. * 🟡 (19:17) Agent searched for HTML files in node_modules: found cytoscape@3.34.0/playwright-page/index.html, katex@0.16.47/contrib/copy-tex/index.html, katex@0.16.47/contrib/auto-render/index.html. None in mermaid package. * 🟡 (19:17) Agent confirmed binpatch/website/src/ has no index.html (only `[...slug].md.ts` page). Astro uses pages/ directory not root index.html. * 🟡 (19:17) Agent tried second fix: removed the static index.html fallback by adjusting vite config — still fails with same error after edit. * 🟡 (19:18) Agent ran DEBUG=vite:* build — no additional debug output captured. Build log saved to /tmp/build.log (14 lines). Confirmed: `output: "static"`, `mode: "static"`, fails at "Building static entrypoints..." stage. * 🟡 (19:19) Agent investigated astro/integrations/hooks.js:170 — confirmed `injectScript: (stage, content) => { updatedSettings.scripts.push({ stage, content }); }` simply stores content. Actual processing deferred to build time. * 🟡 (19:19) Agent found relevant Astro source locations for page scripts: core/build/static-build.js:294 (clientInput.add(PAGE_SCRIPT_ID)), core/build/plugins/plugin-manifest.js:110/142/156, core/build/pipeline.js:89/100. PAGE_SCRIPT_ID = `astro:scripts/page.js`. When any page script exists, it's added to client input bundle. * 🟡 (19:20) Agent located vite-plugin-scripts/index.js — astroScriptsPlugin loads scripts as virtual modules via `load` hook. PAGE_SCRIPT_ID returns code from settings.scripts.filter(s => s.stage === "page"). joined. Vite bundles this virtual module including any imports (like `import mermaid from "mermaid"`). * 🟡 (19:20) Agent hypothesizes root cause: during Astro static build, Vite's
