Source directories for installable extension surfaces. Each subdirectory contains a manifest.json plus js/, css/, and optionally assets/ directories — matching the archive format expected by POST /admin/surfaces/install.

Structure

surfaces/
  build.sh              ← packages each subdir into dist/<name>.surface
  hello-dashboard/      ← sample surface (verifies /s/:slug pipeline)
    manifest.json
    js/main.js
    css/main.css
  icd-test-runner/      ← ICD contract test runner (dev/test tool)
    manifest.json
    js/
    css/

Building

# Build all surfaces → dist/*.surface
./surfaces/build.sh

# Build one
./surfaces/build.sh icd-test-runner

Output goes to dist/ (gitignored). Each .surface file is a zip archive ready for upload via the admin UI or:

curl -X POST https://host/api/v1/admin/surfaces/install \
  -H "Authorization: Bearer $TOKEN" \
  -F "file=@dist/icd-test-runner.surface"

Adding a surface

Create surfaces/<id>/manifest.json with at least id and title
Add js/, css/, assets/ as needed
Run ./surfaces/build.sh <id> to verify it packages
Install via admin UI or API

See EXTENSION-SURFACES.md for the full authoring guide including manifest schema, platform API, and CSS custom properties.

Conventions

id in manifest.json must be unique across all surfaces (core + extension)
Core surfaces (chat, admin, settings, notes, editor) cannot be overridden — the install endpoint returns 409
Surface routes are served at /s/<id> (auto-derived from manifest)
Static assets are served from /surfaces/<id>/js/, /surfaces/<id>/css/
The dist/ directory is gitignored — archives are build artifacts
