fix(render): classify stylesheet surfaces below the app root, not off the absolute path - #528
Conversation
… the absolute path
Under the scaffold container's WORKDIR /app every absolute stylesheet path starts with an app/
segment, so surfaceOf() classified every sheet (site modules, shared/global.scss, @ultimat3/ui)
as app: stylesFor('site') was empty and every site/prerendered document shipped with no
<link rel="stylesheet">.
- render: surfaceUnder(root, file) reads the surface below the root; a node_modules/ sheet is a
package sheet (null). The loader classifies with it against setStylesheetRoot() (cwd when
unset), and naming the root reclassifies sheets registered before it.
- cli: loadApp(root) names the root before importing any module.
- tests: surfaceUnder under /app and /srv/site/x, the loader registry under /app, a real app
prerendered from a root named app/ links its site stylesheet, and the fingerprinted bundle
under /app (own hashed site file; hash stable unless the site CSS changes).

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughStylesheet classification now uses paths relative to a configurable app root. The CLI sets this root before importing app modules. Tests cover root-relative classification, stylesheet bundles, and prerendered output. ChangesStylesheet classification

Resolve a relative root before classifying an absolute stylesheet path.
If loadApp('.') runs from /app, the scan supplies a path such as /app/apps/web/site/page.module.scss. The root . does not match that path. surfaceOf then reads the leading /app/ segment and classifies the site sheet as app. Resolve a relative root against the working directory before the prefix comparison.

packages/render/src/module-loader.tsclassified each stylesheet withsurfaceOf(<absolute path>), andSURFACE_SEGMENTtakes the firstsite|app|api|sharedsegment. The scaffold's own Dockerfile (scaffold-container.ts) runs fromWORKDIR /app, so every absolute path started withapp/. Every sheet (site modules,shared/global.scss, andnode_modules/@ultimat3/ui) was classified asapp.stylesFor('site')was empty, andstyleTag()emitted no<link>, so every site or prerendered page rendered unstyled in production. Routing was not affected: the registry uses root-relative paths.Fix
surfaceUnder(root, file)reads the surface below the root. A file outside the root is read the same way as before. A sheet undernode_modules/counts as a package sheet (null) whatever its directories are called. The loader classifies againstsetStylesheetRoot(root)(new in@ultimat3/render/server), which falls back toprocess.cwd()when unset. Naming the root reclassifies sheets that registered earlier, and bumps the revision only when an answer changes.loadApp(root)names the root before it imports any module.Other
surfaceOf/locateSurfacecallers, audited:routePathFromFile,checkSurfaceBoundary,boundary-cutsandisland-harnessall receive root-relative paths (loadApp/readAppSourcesrelativise first). The stylesheet loader was the only absolute-path caller.Tests (written first, failing before the fix)
surfaces.test.ts:/appand/srv/site/xroots,node_modulessheets, files outside the root,/appleprefix siblingmodule-loader.test.ts: the registry under/app, and reclassification when the root is named after a sheet has loadedprerender-app-root.test.ts: a real app on disk under…/app, prerendered. Before the fix the site document had no<link>. It now links a hashed file that carries the site CSS and the global layer, and noapp/CSS.style-bundle.test.ts: under/app, the site gets its own content-hashed file. Its URL stays the same when the same bytes are re-registered or when app CSS is edited, and changes when the site CSS changes.bun run verify: 14/20 passed, 6 skipped (nothing for them to check at the repo root).🤖 Generated with Claude Code
