# Restructure Plan
Reorganise from flat `shared/sx/ref/` to layered `spec/` + `hosts/` + `web/` + `sx/`.
Recovery point: commit `1a3d7b3` on branch `macros`.
## Phase 1: Directory structure
Create all directories. No file moves.
```
spec/tests/
hosts/python/
hosts/javascript/
web/adapters/
web/tests/
web/platforms/python/
web/platforms/javascript/
sx/platforms/python/
sx/platforms/javascript/
```
## Phase 2: Spec files (git mv)
Move from `shared/sx/ref/` to `spec/`:
- eval.sx, parser.sx, primitives.sx, render.sx
- cek.sx, frames.sx, special-forms.sx
- continuations.sx, callcc.sx, types.sx
Move tests to `spec/tests/`:
- test-framework.sx, test.sx, test-eval.sx, test-parser.sx
- test-render.sx, test-cek.sx, test-continuations.sx, test-types.sx
Remove boundary-core.sx from spec/ (it's a contract doc, not spec)
## Phase 3: Host files (git mv)
Python host - move from `shared/sx/ref/` to `hosts/python/`:
- bootstrap_py.py → hosts/python/bootstrap.py
- platform_py.py → hosts/python/platform.py
- py.sx → hosts/python/transpiler.sx
- boundary_parser.py → hosts/python/boundary_parser.py
- run_signal_tests.py, run_cek_tests.py, run_cek_reactive_tests.py,
run_continuation_tests.py, run_type_tests.py → hosts/python/tests/
JS host - move from `shared/sx/ref/` to `hosts/javascript/`:
- run_js_sx.py → hosts/javascript/bootstrap.py
- bootstrap_js.py → hosts/javascript/cli.py
- platform_js.py → hosts/javascript/platform.py
- js.sx → hosts/javascript/transpiler.sx
Generated output stays in place:
- shared/sx/ref/sx_ref.py (Python runtime)
- shared/static/scripts/sx-browser.js (JS runtime)
## Phase 4: Web framework files (git mv)
Move from `shared/sx/ref/` to `web/`:
- signals.sx → web/signals.sx
- engine.sx, orchestration.sx, boot.sx → web/
- router.sx, deps.sx, forms.sx, page-helpers.sx → web/
Move adapters to `web/adapters/`:
- adapter-dom.sx → web/adapters/dom.sx
- adapter-html.sx → web/adapters/html.sx
- adapter-sx.sx → web/adapters/sx.sx
- adapter-async.sx → web/adapters/async.sx
Move web tests to `web/tests/`:
- test-signals.sx, test-aser.sx, test-engine.sx, etc.
Move boundary-web.sx to `web/boundary.sx`
Move boundary-app.sx to `web/boundary-app.sx`
## Phase 5: Platform bindings
Web platforms:
- Extract DOM/browser primitives from platform_js.py → web/platforms/javascript/
- Extract IO/server primitives from platform_py.py → web/platforms/python/
App platforms:
- sx/sxc/pages/helpers.py → sx/platforms/python/helpers.py
- sx/sxc/init-client.sx.txt → sx/platforms/javascript/init.sx
## Phase 6: Update imports
- All Python imports referencing shared.sx.ref.*
- Bootstrapper paths (ref_dir, _source_dirs, _find_sx)
- Docker volume mounts in docker-compose*.yml
- Test runner paths
- CLAUDE.md paths
## Phase 7: Verify
- Both bootstrappers build
- All tests pass
- Dev container starts
- Website works
- Remove duplicate files from shared/sx/ref/
## Notes
- Generated files (sx_ref.py, sx-browser.js) stay where they are
- The runtime imports from shared.sx.ref.sx_ref — that doesn't change
- Only the SOURCE .sx files and bootstrapper tools move
- Each phase is a separate commit for safe rollback
