<observations> Date: Jul 30, 2026 * 🟡 (16:51) Two shell commands timed out (120000ms and 10000ms timeouts) during the docs preview session — likely leftover `astro/preview` servers. * 🟡 (16:52) Cleanup: killed leftover `astro/preview` processes by PID (806941, 806991, 807036) using `pgrep -af "astro|preview"` and `kill` — PIDs were stale so first `kill` failed with "No such process" but found fresh PID 806991 to kill. * 🟡 (16:52) Verified homepage HTML renders correctly: title `<title>binpatch | binpatch</title>`, hero tagline present, two hero action buttons (`Get Started` → `/installation/`, `View on GitHub` → external), `size-comparison.svg` referenced once. * 🟡 (16:52) Verified rendered footer contains both `<a href="/index.md" class="markdown-link astro-hgus5usv">View as Markdown</a>` link with SVG icon (file shape + lines) AND pagination link `<a href="/_preview/pr-123/installation/" rel="next">` to next page. No EditLink rendered because `editUrl` is not configured for this site. * 🟡 (16:52) Verified all hrefs on homepage are valid: internal links include `/installation/`, `/getting-started/`, `/github-action/`, `/index.md`, `/_preview/pr-123/...` (asset paths), SVG `src="/flow.svg"`, icons (favicon-32.png, favicon.svg, apple-touch-icon.png). External links include GitHub repo, getsentry/cli, npm, daemonology.net/bsdiff, yao-pkg, bun docs, deno docs, nodejs SEA, fossilize. * 🟡 (16:52) Sampled `size-comparison.svg` from `/home/byk/Code/binpatch/website/dist/size-comparison.svg` — proper SVG with `viewBox="0 0 800 420"`, `aria-label` describing 8.1% patch size (2.58 MB vs 31.83 MB for getsentry/cli 0.38.0 → 0.39.0 sentry-linux-x64), inline `<style>` with `.ink { fill: #14171c; }`. * 🟡 (16:52) Verified `index.md` includes the code block content correctly: `import { resolveAndApply } from "binpatch";` with Expressive Code syntax highlighting (purple keywords, yellow strings, gray comments), copy button with data-code payload, "View as Markdown" footer link. * 🟡 (16:53) Read README.md at `/home/byk/Code/binpatch/README.md` (191 lines) — title, npm/CI/license badges, brief description (TRDIFF10/bsdiff+zstd patch chain engine, applies patches, discovers chains from OCI/GHCR or GitHub Releases, generates via composite GitHub Action), "Why" section, "Scope" section, "API" section beginning at line 60. * 🟡 (16:53) Re-read `website/src/content/docs/index.mdx` (164 lines) — frontmatter has title, description (mentions TRDIFF10, bsdiff+zstd, getsentry/cli), template: splash, hero with tagline + 2 actions. Body has sections: "The download size that doesn't scale", "The catch: deltas need two halves", "What you save" (CardGrid with 4 cards: Bandwidth, Wall time, CI minutes, User patience), "How an update flows" (flow.svg), "When to reach for binpatch" (Tabs with syncKey="binary-type", 4 items: Self-updating CLI, Electron/Tauri, Agent/daemon, Game/native), "Get started" with code example. * 🟡 (16:53) Verified all npm package metadata: `binpatch@0.3.1`, type: module, MIT license, description ("Reusable binary delta-update engine: apply TRDIFF10/bsdiff+zstd patch chains to a binary and discover chains from a pluggable source (OCI/GHCR or GitHub Releases).
