-
-#### Phase 7: Pre-Publication Setup
-- [ ] Run `npm pack` to create package tarball
-- [ ] Test packed version locally (`npm install ./testdrive-jsui-1.0.0.tgz`)
-- [ ] Setup npm account (`npm login` or create account)
-- [ ] Decide repository structure (separate repo vs monorepo)
-- [ ] Create git tag: `git tag -a v1.0.0 -m "Release v1.0.0"`
-- [ ] Run final pre-publish checks:
-  - `npm run lint` (no errors)
-  - `npm test` (all tests pass)
-  - `npm run build:prod` (clean build)
-  - `npm publish --dry-run` (verify what will be published)
-
-#### Phase 8: Publication
-- [ ] Publish to npm: `npm publish`
-- [ ] Verify package on npmjs.com
-- [ ] Wait 5-10 minutes, then verify CDN availability:
-  - jsdelivr: `https://cdn.jsdelivr.net/npm/testdrive-jsui@1.0.0/dist/testdrive-jsui.min.js`
-  - unpkg: `https://unpkg.com/testdrive-jsui@1.0.0/dist/testdrive-jsui.min.js`
-- [ ] Create GitHub release from v1.0.0 tag
-- [ ] Test fresh install: `npm install testdrive-jsui marked`
-
-#### Phase 9: Post-Publication
-- [ ] Add npm badges to README.md
-- [ ] Create live demo page (optional)
-- [ ] Setup GitHub Pages for demo (optional)
-- [ ] Create announcements (optional)
-- [ ] Monitor downloads and feedback
-
-### Other Tasks
-- [ ] Make sure that Markitect integration still works fine
-- [ ] Update STANDALONE_PLAN.md and decide if it should be implemented

+## Decision (2026-10-03)
+
+Bernd decided to **retire** the Python standalone plan; its status is `dropped`, not done. Rationale: the npm release does not need the Python engine, the only known consumer (`markitect-main`) keeps its own adapter and is itself being retired, and phases 1, 2, 4 and 5 were never started. If a successor repo later needs a reusable Python engine, start a fresh plan there rather than reviving this one.
