feat: phase 4 admin CMS — dashboard, editor, media, CSRF
Head Hen CMS end-to-end: dashboard lists all posts (drafts + published), Markdown editor with live preview + drag-drop image upload, Pillow media pipeline re-encoding every upload to JPEG, post CRUD + publish toggle + hard delete, About page edit, and double-submit CSRF cookie enforced on every admin mutating endpoint (Phase 3's TODO markers resolved). Slug auto-generated on create and server-locked once a post has been published. Unpublish preserves `published_at` so re-publish keeps original date ordering. Every admin write invalidates the read-side Post/Page TTL caches and records an `auth_events` audit row. CSRF middleware is narrow by design — issues/refreshes the `cb_csrf` cookie only on `GET /admin*`, and mutating endpoints opt in via `require_csrf_form` or `require_csrf_header` Depends. Public routes, healthz, and pre-auth login stay untouched. 64 new tests cover slugs, CSRF, media, admin posts/pages services, and end-to-end CMS routes. Tests never mock the DB — real temp SQLite files per the CLAUDE.md mandate. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

"""Admin-side (write) post service.
|
||||
|
||||
Mirrors the shape of :class:`app.services.posts.PostService` but for
|
||||
the admin CRUD path. Responsibilities:
|
||||
|
||||
- create / update / delete posts
|
||||
- toggle publish state
|
||||
- auto-generate unique slugs from titles on create (draft only)
|
||||
- re-render Markdown to ``body_html_cached`` on every write
|
||||
- audit every write via :class:`AuditService` using descriptive
|
||||
``event_type`` strings
|
||||
- invalidate both :class:`PostService` and :class:`PageService` caches
|
||||
so the public site reflects the change immediately
|
||||
|
||||
All writes use parameterized SQL (``text(":bind")``). No user input is
|
||||
ever interpolated into a query string.
|
||||
|
||||
The service treats ``author_user_id`` as an immutable field: once a
|
||||
post is created, edits do NOT reassign authorship, even if a different
|
||||
admin saves the edit. This matches the single-author ("Head Hen")
|
||||
reality of the site.
|

|
||||
Slug lock-on-publish
|
||||
--------------------
|
||||
A slug may only be auto-regenerated on title change while the post is
|
||||
a draft. Once a post has been published even once, the slug is locked
|
||||
server-side — callers cannot change it via the update path, even if
|
||||
they later unpublish the post. This preserves any inbound links that
|
||||
went live while the post was published.

"""CSRF double-submit cookie service.
|
||||
|
||||
Protects admin-write endpoints against cross-site request forgery by
|
||||
requiring a signed token to be submitted BOTH as a cookie and as a
|
||||
form field / header. An attacker can forge requests but cannot read
|
||||
the cookie (SameSite=Lax blocks cross-site automatic cookie sending,
|
||||
and even if the browser sent it, cross-site JS still cannot read
|
||||
cookies on this origin). Matching the submitted value to the cookie
|
||||
value then proves the request originated from our own pages.
|
||||
|
||||
Design
|
||||
------
|
||||
- The cookie stores a signed opaque nonce. Signing prevents a malicious
|
||||
ad iframe (or any JS on a non-origin page) from producing a cookie
|
||||
value that would later match a crafted form submission.
|
||||
- The nonce itself is 256-bit (``secrets.token_urlsafe(32)``), generated
|
||||
per-browser on first admin GET and reused for the session. Rotating
|
||||
per request would invalidate any still-open admin tab on every nav,
|
||||
which the small-scale admin UX cannot tolerate.
|
||||
- Verification unsigns the submitted token and compares the raw nonce
|
||||
to the raw nonce unsigned from the cookie using :func:`hmac.compare_digest`
|
||||
(constant-time) to foreclose timing side channels.
|
||||
- The cookie is ``HttpOnly=False`` so the minimal admin JS (live
|
||||
preview, upload) can read it to set the ``X-CSRF-Token`` header on
|
||||
fetch requests. This is the conventional double-submit cookie setup
|
||||
— the XSS risk is already mitigated by the Markdown sanitizer and
|
||||
the session cookie remains HttpOnly.
|
||||
|
||||
The service is a small collaborator: it does not know about FastAPI
|
||||
routes, request objects, or templates. The :mod:`app.dependencies.csrf`
|
||||
module wraps the verify call in a FastAPI dependency.

"""Image upload pipeline: validate → re-encode → store → record.
|
||||
|
||||
Every admin image upload passes through this service. The contract is
|
||||
strict on purpose — the site serves user-editable HTML (via the
|
||||
sanitizer) plus the bytes that flow through here, so anything we miss
|
||||
becomes XSS / RCE surface area.
|
||||
|
||||
Steps in :meth:`MediaService.save_upload`:
|
||||
|
||||
1. **Size cap** — reject anything over 8 MB at the bytes level
|
||||
(before decoding). We read the full buffer so we can hash and
|
||||
re-encode it; streaming would complicate Pillow's decode path and
|
||||
upload volumes are tiny.
|
||||
2. **Magic-byte check** — :mod:`python-magic` inspects the first
|
||||
2048 bytes and yields a MIME type. Anything not in our allowlist
|
||||
(``image/jpeg``, ``image/png``, ``image/webp``) is rejected.
|
||||
Notably, ``image/gif`` is NOT allowed — animated GIFs have a long
|
||||
history of ambiguous / abuse-friendly encodings.
|
||||
3. **Pillow decode** — open via :func:`PIL.Image.open` on a
|
||||
:class:`io.BytesIO` wrapper. Call ``.verify()`` on a dedicated copy
|
||||
(it consumes the stream), then re-open for the actual encode path.
|
||||
Reject anything larger than 10000 px per side as a defense against
|
||||
decompression bombs.
|
||||
4. **Re-encode to JPEG** — always JPEG. Strip metadata by reopening
|
||||
into a clean :class:`PIL.Image.Image`; flatten alpha on a white
|
||||
background so transparent PNG / WebP images don't render as black.
|
||||
5. **Store** — write to ``<media_root>/<yyyy>/<mm>/<random>.jpg`` where
|
||||
the random component is :func:`secrets.token_urlsafe(16)`. The
|
||||
client-supplied filename is kept only in the DB row's
|
||||
``original_filename`` for display; it is NEVER used to build a
|
||||
filesystem path.
|
||||
6. **DB row** — insert a :class:`Media` row. Return the loaded
|
||||
dataclass.

|

* 2. Drag-and-drop image upload (POST /admin/media/upload, insert

* Everything is scoped to elements carrying `data-editor` (textarea)

* on any page without side effects elsewhere.
|

*
|
||||
* Security contract:
|
||||
* - The X-CSRF-Token header is read from the <meta name="csrf-token">
|
||||
* tag rendered by the admin base template. Missing / empty token
|
||||
* means the server will 403 — we do NOT try to hide the button.
|
||||
* - The /admin/preview response is ALREADY sanitized server-side
|
||||
* through the same bleach allowlist that gates every persisted
|
||||
* body_html_cached value (see app/services/markdown.py). We swap
|

## Phase 4 — Admin CMS
|
||||
|
||||
Pre-requisites:
|
||||
- Logged in via the Phase 3 magic-link flow (dev-fallback URL in server logs).
|
||||
- Landed on the Phase 4 dashboard at `/admin`.
|
||||
|
||||
### Dashboard (`/admin`)
|
||||
|
||||
- [ ] Page returns 200.
|
||||
- [ ] Page title reads **"Dashboard"**.
|
||||
- [ ] Signed-in email appears in the greeting.
|
||||
- [ ] Posts table lists the seeded **"Welcome to the Farm"** row with status **Published**.
|
||||
- [ ] Each row shows Edit / Publish-or-Unpublish / Delete buttons.
|
||||
- [ ] Delete click triggers a confirmation dialog.
|
||||
- [ ] "New post" button is visible and links to `/admin/posts/new`.
|
||||
- [ ] "Edit About" button links to `/admin/pages/about/edit`.
|
||||
- [ ] `<meta name="csrf-token">` is present in the rendered HTML (view source).
|
||||
- [ ] The `cb_csrf` cookie is set with `SameSite=Lax`, `HttpOnly=false` (readable by JS).
|
||||
|
||||
### Create a post (`/admin/posts/new`)
|
||||
|
||||
- [ ] Form renders without errors.
|
||||
- [ ] Title + status + body fields visible; preview pane on the right.
|
||||
- [ ] Drop zone is visible below the textarea with prompt copy.
|
||||
- [ ] Typing in the textarea causes the preview to update within ~300ms.
|
||||
- [ ] Dragging a JPG / PNG / WebP image onto the drop zone uploads it; a Markdown image tag is inserted at the cursor.
|
||||
- [ ] Dropping a GIF, plain text file, or anything >8 MB triggers the `.is-error` state on the drop zone.
|
||||
- [ ] Submitting with a blank title re-renders with "Title is required." and preserves other fields.
|
||||
- [ ] Submitting a valid form 303-redirects to `/admin?msg=created`.
|
||||
|
||||
### Edit a post (`/admin/posts/{id}/edit`)
|
||||
|
||||
- [ ] Form is pre-populated with the post's current title + body.
|
||||
- [ ] Slug is rendered read-only below the title.
|
||||
- [ ] For a published post, the UI notes the slug is locked.
|
||||
- [ ] Saving updates the row; public `/` reflects the change immediately (no caching delay).
|
||||
|
||||
### Publish / unpublish / delete
|
||||
|
||||
- [ ] Publish button on a draft row flips the status to published and shows a "published" flash on the next dashboard load.
|
||||
- [ ] Unpublish button on a published row flips the status back to draft; `published_at` is preserved in the DB (check via `sqlite3 data/app.db`).
|
||||
- [ ] Delete button on any row removes it entirely after confirmation.
|
||||
|
||||
### About page edit (`/admin/pages/about/edit`)
|
||||
|
||||
- [ ] Form renders with the current About title and body.
|
||||
- [ ] There is no slug editor.
|
||||
- [ ] Saving updates the row and the public `/about` page on next load.
|
||||
|
||||
### Media upload
|
||||
|
||||
- [ ] `data/media/<yyyy>/<mm>/` is created lazily the first time an image is saved.
|
||||
- [ ] Uploaded files are stored under a random filename ending in `.jpg` regardless of the source format.
|
||||
- [ ] Hitting the `/media/<yyyy>/<mm>/<name>.jpg` URL directly serves the image at HTTP 200.
|
||||
- [ ] An uploaded transparent PNG comes through as an RGB JPEG (transparent areas become white).
|
||||
- [ ] Uploading an animated GIF is rejected with a generic error.
|
||||
- [ ] Uploading a >8 MB file is rejected.
|
||||
- [ ] Uploading while the `X-CSRF-Token` header is missing returns 403.
|
||||
|
||||
### CSRF
|
||||
|
||||
- [ ] Admin POST routes (`/admin/logout`, `/admin/posts`, `/admin/posts/*/delete`, `/admin/posts/*/publish`, `/admin/pages/about`, `/admin/media/upload`, `/admin/preview`) all return 403 when the submitted token does not match the cookie.
|
||||
- [ ] A legitimate form submission succeeds because both the cookie and the form field were issued during the previous GET.
|
||||
|
||||
### Public site regression
|
||||
|
||||
- [ ] `/` shows only published posts (newly created drafts do NOT appear).
|
||||
- [ ] A newly-published post shows at the top of `/` within one request.
|
||||
- [ ] `/about` shows the most recently edited copy.
|
||||
- [ ] No admin-facing text (status, dashboard wording) leaks into the public HTML.
|
||||

## Phase 4 — Admin CMS ✅
|
||||
|
||||
- `/admin` dashboard: lists pages + posts, links to edit.
|
||||
- Markdown editor: textarea + live preview + drag-and-drop image upload. Prefer minimal hand-rolled (a single `textarea` + `fetch`-based upload) over a heavy library; EasyMDE acceptable only if the minimal path proves clunky in manual testing.
|
||||
- Media upload endpoint: magic-byte validation, 8 MB cap, Pillow re-encode (JPEG/WebP/PNG), random storage name under `data/media/<yyyy>/<mm>/<random>.<ext>`.
|
||||
- CRUD: pages (About), posts (blog) with publish toggle and slug auto-gen.
|
||||
- Save path: markdown → `markdown-it-py` → `bleach` allowlist → stored in `body_html_cached`.
|
||||
**Completed:** 2026-04-22
|
||||
|
||||
**Summary:** Shipped the full Head Hen CMS: dashboard listing every post (drafts + published, newest `updated_at` first) plus an About-edit entry point, a hand-rolled Markdown editor (textarea + 300 ms-debounced server-side live preview + drag-drop image upload), a hardened media pipeline (magic-byte sniff → 8 MB cap → Pillow re-encode to JPEG with alpha flattened on white → random `data/media/<yyyy>/<mm>/<token>.jpg`), post create/update/publish-toggle/hard-delete with slug auto-gen and lock-on-publish, and double-submit CSRF cookie enforced on every admin mutating endpoint. Phase 3's `# TODO(phase-6-csrf)` markers are resolved — CSRF is live.
|
||||
|
||||
**Key files:**
|
||||
- `app/services/slugs.py` — `slugify(title)` pure helper (lowercase, ASCII, collapse/trim hyphens) + `ensure_unique(engine, slug, table)` collision resolver that appends `-2`, `-3`, etc.
|
||||
- `app/services/csrf.py` — `CSRFService`: issue/verify round-trip via `URLSafeTimedSerializer(secret_key, salt="csrf")`. Cookie `cb_csrf`, `HttpOnly=False` (JS reads it for fetch), `SameSite=Lax`, `Secure` in production. Separate from the `cb_session` session cookie.
|
||||
- `app/dependencies/csrf.py` — `require_csrf_form` (form-field `csrf_token`) + `require_csrf_header` (`X-CSRF-Token` — used by upload + preview because those are fetch-based). Both raise 403 on mismatch.
|
||||
- `app/services/media.py` — `MediaService(engine, media_root)`; `save_upload(file, uploaded_by) -> Media`. Magic-byte check via `python-magic` (accept `image/jpeg|png|webp`; reject GIF and everything else), 8 MB cap returning 413 intent, Pillow verify+reopen, alpha-composite RGBA/P onto white, `.save(path, "JPEG", quality=85, optimize=True)`. `secrets.token_urlsafe(16)` filename; client extension discarded. Monthly partition dir auto-created.
|
||||
- `app/services/admin_posts.py` — write-side `AdminPostsService`: `list_all/get_by_id/create/update/toggle_publish/delete`. Slug set once at create and never rewritten by `update()` (server-enforced lock). `published_at` set on first publish and preserved across unpublish/republish. Every write invalidates the read-side `PostService` cache.
|
||||
- `app/services/admin_pages.py` — About-only write service; slug immutable. Invalidates `PageService` cache on write.
|
||||
- `app/routes/admin_cms.py` — new router: `GET /admin` (dashboard), `GET /admin/posts/new`, `POST /admin/posts`, `GET /admin/posts/{id}/edit`, `POST /admin/posts/{id}`, `POST /admin/posts/{id}/delete`, `POST /admin/posts/{id}/publish`, `GET /admin/pages/about/edit`, `POST /admin/pages/about`, `POST /admin/media/upload`, `POST /admin/preview`. All mutating routes carry `require_admin` + a CSRF dep.
|
||||
- `app/templates/admin/dashboard.html` + `post_form.html` + `page_form.html` + `_post_row.html` — CMS UI. Post form reused for create + edit; slug field read-only when status=published.
|
||||
- `app/static/js/admin_editor.js` — hooks `[data-editor]`: 300 ms-debounced `POST /admin/preview` with `X-CSRF-Token` header, swaps preview via `<template>` + `cloneNode` (never `innerHTML`); drag-drop / file-picker upload to `/admin/media/upload` with FormData, inserts `` at the textarea cursor.
|
||||
- `app/templates/admin/base.html` — added `<meta name="csrf-token">`, hidden CSRF input in the logout form, dashboard nav link, optional `{% block scripts %}`.
|
||||
- `app/main.py` — instantiates `CSRFService`, `MarkdownService`, `AdminPostsService`, `AdminPagesService`, `MediaService`; mounts `/media` StaticFiles on `settings.media_root` (eager `mkdir(parents=True, exist_ok=True)`); installs `CSRFCookieMiddleware` that issues/refreshes `cb_csrf` + exposes `request.state.csrf_token` **only on `GET /admin*`** so public / `/healthz` / pre-auth login stay untouched; includes `admin_cms_router`.
|
||||
- `app/routes/admin.py` — removed the placeholder `GET /admin` handler (moved), added `require_csrf_form` to `POST /admin/logout`, stripped the `# TODO(phase-6-csrf)` comments.
|
||||
- `app/config.py` — added `media_root: str = Field(default="data/media")`.
|
||||
- `.env.example` — added `MEDIA_ROOT=data/media`.
|
||||
- `.gitignore` — carved out `!data/media/.gitkeep` so the mount dir survives checkouts.
|
||||
- `app/static/css/site.css` — extended with `.admin-dashboard`, `.post-table`, `.editor` (2-column layout at 48rem+), `.drop-zone`, `.status-badge`, `.btn--danger/.btn--secondary/.btn--link`, `.admin-flash`.
|
||||
- `docs/MANUAL_TESTING.md` — appended Phase 4 checklist.
|
||||
- Tests: `test_slugs.py`, `test_csrf_service.py`, `test_media_service.py`, `test_admin_posts_service.py`, `test_admin_pages_service.py`, `test_admin_cms_routes.py` — 64 new tests; also updated `test_admin_routes.py` for the relocated welcome template + the now-required logout CSRF field.
|
||||
|
||||
**Endpoints created:**
|
||||
- `GET /admin` — dashboard (lists all posts + About-edit entry). Replaces Phase 3 placeholder.
|
||||
- `GET /admin/posts/new` — create form.
|
||||
- `POST /admin/posts` — create handler (CSRF form).
|
||||
- `GET /admin/posts/{id}/edit` — edit form.
|
||||
- `POST /admin/posts/{id}` — update handler (CSRF form). Slug field is server-ignored when post is published.
|
||||
- `POST /admin/posts/{id}/delete` — hard delete with confirmation (CSRF form).
|
||||
- `POST /admin/posts/{id}/publish` — publish/unpublish toggle (CSRF form).
|
||||
- `GET /admin/pages/about/edit` — About edit form.
|
||||
- `POST /admin/pages/about` — About update (CSRF form). Slug immutable.
|
||||
- `POST /admin/media/upload` — multipart upload; returns `{"url": "/media/...", "alt": ""}` JSON (CSRF header).
|
||||
- `POST /admin/preview` — Markdown → sanitized HTML preview fragment (CSRF header).
|
||||
- `Mount /media` — `StaticFiles` serving `data/media/<yyyy>/<mm>/<token>.jpg`.
|
||||
|
||||
**Key details:**
|
||||
- **CSRF gating is narrow by design.** The middleware only issues/refreshes `cb_csrf` on `GET /admin*`; public routes, `/healthz`, `GET /admin/login`, and `GET /admin/auth/consume/{token}` never see it. Mutating endpoints opt into verification via an explicit `require_csrf_form` or `require_csrf_header` Depends — no blanket middleware that could accidentally block the public site.
|
||||
- **Slug lock is server-enforced.** `AdminPostsService.update` never rewrites `slug`; a malicious POST submitting a new slug field is ignored. Slug only exists because `create()` set it.
|
||||
- **Unpublish preserves `published_at`.** Re-publishing a previously-published post keeps its original date so the homepage ordering doesn't jump.
|
||||
- **Media pipeline: single output format (JPEG).** Simpler write-side, smaller files, predictable downstream behaviour. RGBA / paletted inputs get alpha-composited onto white before encode.
|
||||
- **Preview endpoint swap uses `<template>` + `cloneNode`, not `innerHTML`.** Server-side `bleach` is still the single trust boundary; this is defense-in-depth for the admin JS.
|
||||
- **Audit trail extends cleanly.** New event types (`post_created`, `post_updated`, `post_deleted`, `post_published`, `post_unpublished`, `page_updated`, `media_uploaded`) reuse the Phase 3 `auth_events` table — `event_type` was left free-form for exactly this reason.
|
||||
- **No DB mocking.** Every new test uses a real temp SQLite file per the CLAUDE.md mandate; the env-reload fixture pattern from Phase 3's `test_admin_routes.py` is reused.
|
||||
- **Phase 5 hook:** Contact form POST will get `require_csrf_form` for free — the infrastructure is in place.
|
||||
- **Phase 6 deferred items still standing:** nonce-based CSP, HSTS, access-log middleware, non-root Docker user. None blocked Phase 4.
