Motivation

  • Preserve the site's UI and navigation as a presentable archive while explicitly indicating the project is no longer actively operated.
  • Avoid attempting to restore unavailable runtime services (analytics, feature flags, dynamic screenshots, tRPC) and instead show honest fallbacks.
  • Provide a clear, visible archive notice and a short retrospective so visitors understand what worked, what is retired, and why interactive parts may be limited.

Description

  • Add UI components ArchiveNotice and ArchiveOverview and integrate them into the Next.js and Astro layouts so an archive banner and metadata are shown site-wide (packages/ui/src/archive-notice.tsx, packages/ui/src/archive-overview.tsx, injected in packages/ui/src/layout-content.tsx and apps/projekte/src/layouts/Layout.astro).
  • Replace live preview screenshot infrastructure with static fallbacks by changing the preview API to redirect to a local archive-project.svg and adding neutral placeholder SVGs (apps/projekte/src/pages/api/preview/..., apps/web/public/archive-project.svg, apps/projekte/public/archive-project.svg), and update ProjectCard image error handling to use that fallback.
  • Retire runtime integrations and replace runtime endpoints with archive responses by removing microfrontend middleware, disabling PostHog instrumentation, retiring flag discovery, and returning explicit 410/archived responses for tRPC and flags endpoints, while simplifying Next.js layout to avoid requiring those services (apps/web/src/app/layout.tsx, apps/web/src/instrumentation-client.ts, apps/web/src/app/api/trpc/[trpc]/route.ts, apps/web/src/app/api/2well2know/vercel/flags/route.ts, deleted apps/web/src/middleware.ts).
  • Preserve navigation and representative project flows while making homepage project selection deterministic and adding in-place archive documentation and metadata to the README.md and /about page so the archive explains what was learned and which integrations were intentionally retired.

Testing

  • Ran Rust tests for crates with cargo test --workspace --lib --bins, which completed successfully (non-doctest unit/binary tests passed with warnings).
  • Running the full cargo test --workspace revealed legacy doctest failures tied to historical Rust examples and private/unlinked modules which were left as historical artifacts and not rewritten.
  • bun install failed due to HTTP 403 responses from the npm registry so bun run build / bun run check (Turbo) could not be executed, and dependency installation/build were therefore not completed.
  • Miscellaneous repository checks succeeded: git diff --check and python3 -m json.tool validation for package.json and projects.json passed, while cargo fmt --all -- --check reported some formatting diffs in Rust sources (pre-existing).

Codex Task

Summary by CodeRabbit

  • New Features

    • Added archive notices and an overview describing the 2025 project week, source, status, and maintainer.
    • Added an archived-demo fallback for unavailable project previews.
    • The About page now presents the project’s history and archival status.
    • Featured projects are now displayed consistently.
  • Changes

    • Retired backend, feature-flag, analytics, deployment, and protection services.
    • API requests for retired services now return an archived response.
    • Updated page metadata and archival messaging throughout the interface.

Note

Archive project UI and retire dynamic backends (PostHog, tRPC, Puppeteer previews)

  • Adds ArchiveNotice and ArchiveOverview shared components, rendered across web and Astro pages, and a new /archive-project.svg fallback for failed project preview images.
  • Replaces the /about Maintenance page with a German archive overview describing the 2025 project week, retired services, and archive policy.
  • Retires the preview API: apps/projekte/src/pages/api/preview/[year]/[username]/[project].ts no longer launches Puppeteer/Chromium; every request 302-redirects to the local SVG asset.
  • Removes PostHog initialization from apps/web/src/instrumentation-client.ts, apps/web/src/app/global-error.tsx, apps/web/src/app/layout.tsx, and apps/projekte/src/layouts/Layout.astro; tRPC handler and Vercel Flags route now return 410.
  • Strips Vercel microfrontend middleware, toolbar config, and Bot ID client from apps/web/next.config.ts, apps/web/src/middleware.ts, and root layout.
  • Makes featured project selection deterministic in getFeaturedProjects by dropping the shuffle step.
  • Risk: apps/web/src/app/api/trpc/[trpc]/route.ts and apps/web/src/app/api/2well2know/vercel/flags/route.ts now return 410 for all requests; any in-tree or external tRPC clients will break. PostHog analytics and Vercel toolbar are fully removed with no fallback. The preview API no longer loads external project sites, so live screenshots are unavailable.

Review Change Stack

Walkthrough

The project-week applications now present archived content, disable retired live services, use static project-preview fallbacks, and return archived responses from former API endpoints.

Changes

Archive content and shared UI

Layer / File(s) Summary
Archive content and stable landing pages
README.md, packages/ui/src/archive-notice.tsx, packages/ui/src/archive-overview.tsx, packages/ui/src/layout-content.tsx, packages/ui/src/pages/root.tsx, apps/web/src/app/about/page.tsx
Archive notices and metadata are shown across layouts and pages. The landing page uses stable featured projects and includes retrospective content. Print handling is deferred until print styles apply.
Archived project previews and detail pages
apps/projekte/src/components/ProjectCard.astro, apps/projekte/src/pages/api/preview/[year]/[username]/[project].ts, apps/projekte/src/pages/projekte/[year]/[participant]/[project].astro, apps/projekte/src/layouts/Layout.astro, packages/ui/src/project-showcase.tsx
Project previews use /archive-project.svg. The preview API redirects to that asset. Project pages identify external sites as potentially offline and remove the analytics component.

Web runtime and service retirement

Layer / File(s) Summary
Retired integrations and archived API responses
apps/web/next.config.ts, apps/web/src/app/api/2well2know/vercel/flags/route.ts, apps/web/src/app/api/trpc/[trpc]/route.ts, apps/web/src/middleware.ts
Microfrontend, bot-protection, feature-flag, and tRPC integrations are removed or return HTTP 410 responses. Related rewrites and middleware are removed.
Static application shell and analytics removal
apps/web/src/app/layout.tsx, apps/web/src/app/global-error.tsx, apps/web/src/instrumentation-client.ts
The root layout uses fixed archive metadata and removes service providers. Error reporting and client analytics initialization are no longer active.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 431e8

The archive remains mergeable, but printing, narrow-screen navigation, and fallback-image accessibility have localized regressions worth fixing.

Poem

A rabbit inspects the archive sign,
Finds old project previews in line.
The backend now sleeps,
While history it keeps,
And static pages safely shine.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR performs a broad production decommissioning: it retires dynamic previews and backend APIs, removes microfrontend/bot-protection/analytics integrations, and adds new archive UI across both applications. It also leaves a medium-severity metadata-host concern and lacks successful web build validation, so the runtime and deployment effects warrant human review.

Not approved because:

🟡 Changes recommended

The removal of the /.well-known/... rewrite means the retired flags discovery URL will likely return 404 instead of the intended explicit archived 410 response.

Pull request overview

This PR converts the site into a “static archive” experience by adding prominent archive UI, removing/retiring runtime-only integrations (microfrontends, analytics, feature flags, tRPC), and replacing dynamic preview screenshots with local placeholders so the UI remains presentable without external services.

Changes:

  • Added ArchiveNotice / ArchiveOverview components and integrated them into Next.js + Astro layouts for consistent archive messaging.
  • Replaced dynamic screenshot generation and preview fallbacks with a local archive-project.svg placeholder and updated image error handling.
  • Retired runtime backends/integrations (microfrontends middleware, PostHog client init, flags discovery, tRPC) and replaced endpoints with explicit archived/410 responses.

Derive the header offset from the archive banner height.

Line 90 assumes that .archive-note is always 42px tall. On narrow screens, the text at lines 188-190 wraps and the fixed banner exceeds that height. The higher-z-index banner then covers part of the header overlay and its controls.

Use a responsive offset that matches the rendered archive banner height.

Preserve the theme captured before keyboard printing.

Line 61 runs after the light-theme update can commit. The beforeprint handler then overwrites originalThemeRef.current with "light". afterprint restores light instead of the user's original dark or system theme.

Keep separate keyboard-print state, or prevent handleBeforePrint from replacing the saved theme during the scheduled print flow.

Update the fallback image’s alt text.

When the preview fails, this handler displays /archive-project.svg but keeps the existing alt value, Screenshot von ${project.projectTitle}. Assistive technology then describes the archive placeholder as the project screenshot. Set target.alt to the archive description, as apps/projekte/src/components/ProjectCard.astro does.
