+# MVP Plan: Doodle Addon for Plone
+
+A minimal Doodle-like addon for Plone with folderish and date content types, permissions, and a Bootstrap-styled doodle view with participant selection toggle.
+
+---
+
+## Completed MVP (All Tests Passing ✅)
+
+### Content Types
+- ✅ `experimental.doodle.folder` (folderish container type)
+- ✅ `experimental.doodle.date` (date item with participants set field)
+
+### Browser View & Interaction
+- ✅ Doodle view renders sorted dates in a responsive table
+- ✅ Participants displayed as Bootstrap badge pills
+- ✅ Toggle button for current user participation (POST-based with CSRF protection)
+- ✅ Participation redirect back to referrer or doodle view
+
+### UI/Styling
+- ✅ Bootstrap-compatible markup (card, table-striped, badge, btn-primary)
+- ✅ Responsive layout with table-responsive wrapper
+- ✅ Minimal custom CSS (badge flex-wrap, button nowrap)
+- ✅ Bundle registration via csscompilation field (Plone 6.x pattern)
+
+### Permissions & Access Control
+- ✅ Custom add permissions for both types
+- ✅ Browser layer registration active
+- ✅ CSRF token validation on participation toggle
+- ✅ Anonymous user rejection on toggle attempt
+
+### Tests (15 Passed)
+- ✅ 10 setup tests (install, uninstall, browser layer, permissions, type registration)
+- ✅ 1 testing profile test
+- ✅ 1 doodle view test (sorted dates rendering)
+- ✅ 1 participation toggle test
+- ✅ Code lint & quality (ruff, pyroma 10/10, zpretty, python-versions)
+
+---
+
+## Key Implementation Details
+
+**Files:**
+- `src/experimental/doodle/browser/doodle.pt` — Template with Bootstrap markup + tal:attributes for dynamic classes
+- `src/experimental/doodle/browser/doodle.py` — View with rows() and date_label() methods
+- `src/experimental/doodle/browser/participation.py` — ToggleParticipationView with CSRF check
+- `src/experimental/doodle/browser/static/doodle.css` — Minimal responsive utilities
+- `src/experimental/doodle/profiles/default/registry/main.xml` — Bundle registration
+
+**Key Decisions:**
+- Two separate types for structural clarity
+- `participants` field as set of user IDs (not explicit selection field)
+- POST-based toggle pattern for atomic updates
+- Bootstrap-first styling aligned with Plone 6.x defaults
+- explicit tal:attributes for class binding (not string interpolation)
+
+---
+
+## Next Atomic Steps (Post-MVP)
+
+1. **Results/Summary View** — Display vote counts per date (new view method, optional aggregation UI)
+2. **Control Panel** — Registry settings for participation notifications/preferences
+3. **Catalog Indexing** — Add doodle-specific indexes for efficient queries (if scaling)
+4. **Edge Case Tests** — Validate CSRF token reuse, anonymous rejection, data persistence
+5. **Advanced Features** — Date filtering, search, results export
+
+---
+
+## Session Status
+Session completed with all quality gates green. Ready for code review or feature expansion.
