 - Do not add noisy boilerplate to trivial `__str__` methods, simple properties, or obvious one-line helpers unless the surrounding file genuinely benefits.

+# Frontend Component Structure Guidelines
+
+- Avoid growing a flat `frontend/src/components/` directory.
+- Put app-owned presentational or interactive components that combine shadcn primitives with project-specific functionality in `frontend/src/components/elements/`.
+- Put shared structural components in `frontend/src/components/layout/`.
+- Keep `frontend/src/components/ui/` for shadcn components installed directly by `npx shadcn@latest add <component>`.
+- Put provider-style wrappers and context composition in `frontend/src/providers/`.
+- Put route-local components in `frontend/src/app/**/_components/` when they are only used by a single route.
+- Put route page tests beside the page or route-local component they cover within the same `frontend/src/app/**` directory.
+- For app-owned folders under `frontend/src/components/elements/`, `frontend/src/components/layout/`, `frontend/src/providers/`, and `frontend/src/app/**/_components/`, let the folder name carry the component or provider name and use `index.tsx`, `index.test.tsx`, and `index.stories.tsx` for colocated files.
+- Do not add barrel `index.ts` files inside those component or provider folders unless a task explicitly needs a separate module boundary.
+- Preserve shadcn's generated file naming and structure inside `frontend/src/components/ui/`; do not wrap those generated components in extra folders just to match the app-owned component pattern.
+- For new Storybook stories that use `tags: ["autodocs"]`, set `parameters.docs` to the shared compact docs helper in `frontend/src/lib/storybook-docs.tsx` so the Docs tab omits the default `Stories` block and uses the reduced primary canvas height.
+
+## Preferred Shapes
+
+Shared reusable component:
+
+```text
+frontend/src/components/elements/StatusBadge/
+  index.tsx
+  index.stories.tsx
+  index.test.tsx
+```
+
+Shadcn-installed primitive:
+
+```text
+frontend/src/components/ui/button.tsx
+```
+
+Shared provider:
+
+```text
+frontend/src/providers/ThemeProvider/
+  index.tsx
+  index.test.tsx
+```
+
+Route-local component:
+
+```text
+frontend/src/app/projects/[id]/_components/MemberInviteCard/
+  index.tsx
+  index.stories.tsx
+  index.test.tsx
+```
+
+Route page with colocated test:
+
+```text
+frontend/src/app/admin/sources/
+  page.tsx
+  page.test.tsx
+```
+
+## Placement Heuristics
+
+- If the component is a shadcn primitive created by the CLI, keep it under `components/ui/` with the generated naming.
+- If the component is app-owned and composes shadcn primitives with project-specific behavior or presentation, place it under `components/elements/`.
+- If the component primarily arranges shared navigation or page chrome, place it under `components/layout/`.
+- If the module primarily provides context or wraps app trees with provider logic, place it under `providers/`.
+- If the component is only consumed by one route segment, keep it under that route's `_components/` folder instead of promoting it to `components/`.
+- Prefer folder-level naming over duplicate file naming. For example, prefer `OriginalContentIdeaCard/index.tsx` over `OriginalContentIdeaCard/OriginalContentIdeaCard.tsx`.
+- When extracting from a large page, prefer moving the smallest reusable visual leaves first, then larger feature sections, while keeping the page as the orchestration layer.
+- Prefer `*.test.tsx` files beside the owning page or component over `__tests__/` directories for new frontend tests.
+
+## Notes
+
+- Preserve the existing backend contract and keep frontend payloads in `snake_case`.
+- Follow the repo's colocated story convention for Storybook.
+- Reuse `frontend/src/lib/storybook-docs.tsx` for compact Docs tabs in new stories instead of re-declaring the same docs page JSX in each file.
+- Do not move files only to satisfy the structure guideline unless the current task already touches that area.

 - For Provider/Wrapper components, do not test state or initialization. Instead, render a consumer child component and assert that the context values or library configurations (like QueryClient options) match the expected project defaults.

-## Current focus
-
-Phase 3 WP5: original content idea generation in `trends/`.
-
-## What landed today
-
-- Added `OriginalContentIdeaStatus` and `OriginalContentIdea` to `trends/models.py`.
-- Added migration `trends/migrations/0005_original_content_idea.py`.
-- Added new prompt skill folder `skills/original_content_ideation/` with:
-	- `SKILL.md`
-	- `resources/gap_detect.md`
-	- `resources/generate.md`
-	- `resources/critique.md`
-- Added partial WP5 task implementation in `trends/tasks.py`:
-	- `run_all_original_content_idea_generations`
-	- `generate_original_content_ideas`
-	- workflow helpers for accept / dismiss / mark written
-	- heuristic gap detection + fallback generation + heuristic critique
-	- optional OpenRouter-backed prompt-resource calls for gap detect / generate / critique
-- Added partial task coverage in `trends/tests/test_tasks.py` for:
-	- pending-idea creation
-	- weekly cap
-	- mark-written workflow
-
-## What was validated
-
-- `python manage.py check`
-- `python manage.py makemigrations --check --dry-run trends`
-
-Both passed after naming the new model index `core_idea_project_7f21_idx`.
-
-## Known incomplete state
-
-- WP5 is not finished.
-- No serializer/API route/test work has been added yet for `OriginalContentIdea`.
-- `docs/IMPLEMENTATION_PHASE_3.md` still needs a current implementation note for WP5 once the backend slice is complete.
-- The focused task validation was interrupted:
-	- first `pytest trends/tests/test_tasks.py -q` failed on a duplicate `_build_theme_cluster_context` definition introduced during editing
-	- that duplicate definition was removed
-	- the rerun was cancelled because we paused for shutdown
-- After that, additional external edits were reported in:
-	- `docs/IMPLEMENTATION_PHASE_3.md`
-	- `trends/tasks.py`
-	- `trends/tests/test_tasks.py`
-	Re-read those files before making new edits tomorrow.
-
-## First steps tomorrow
-
-1. Confirm the active branch. The repo attachment reported `maintenance/finish-core-refactor`, but an earlier terminal action created `feature/original-content-idea-generation`, so verify before continuing.
-2. Re-read:
-	 - `trends/tasks.py`
-	 - `trends/tests/test_tasks.py`
-	 - `docs/IMPLEMENTATION_PHASE_3.md`
-3. Run the focused validation that was interrupted:
-	 - `pytest trends/tests/test_tasks.py -q`
-4. If task tests pass, finish the remaining WP5 slice:
-	 - `trends/serializers.py`
-	 - `trends/api.py`
-	 - `trends/api_urls.py`
-	 - `trends/tests/test_api.py`
-	 - optional admin only if needed
-	 - add WP5 implementation note to `docs/IMPLEMENTATION_PHASE_3.md`
-5. After API work, run focused validation again:
-	 - `pytest trends/tests/test_tasks.py trends/tests/test_api.py -q`
-	 - `python3 -m mypy trends/tasks.py`
-
-## Likely follow-up checks
-
-- Watch for unused imports in `trends/tasks.py` (`build_skill_user_prompt` / `get_skill_definition` may no longer be needed for WP5 helpers).
-- Confirm the new heuristic tests still pass after any formatter changes.
-- Keep WP5 scoped to backend + docs for now; frontend `/ideas` work belongs to WP6.
