Implements the public-content-visibility OpenSpec change. Adds the
smallest social surface that lets us demo the product to logged-out
visitors without user signup.
Schema:
- `visibility text NOT NULL DEFAULT 'private'` on routes + activities.
- Shared Visibility type exported from the schema module.
Access:
- New canView(content, viewer, { asDirectLink }) helper in auth.server.ts
centralises the rule: public → anyone; unlisted → anyone on direct
link; private → owner only.
- routes.$id and activities.$id loaders return 404 (not 403) when
canView rejects, so existence of private content isn't leaked.
- Detail pages emit Open Graph + Twitter Card meta on public/unlisted
content only.
Editing:
- Visibility <select> on routes/:id/edit with owner-only access.
- Activity detail page gets a small visibility form + set-visibility
action intent (no separate activity-edit page needed).
- EN + DE i18n under routes.visibility.* and activities.visibility.*.
Listings:
- Listing helpers listPublicRoutesForOwner / listPublicActivitiesForOwner
for cross-user queries. Existing owner-scoped listRoutes/listActivities
stay — owners see their own content regardless of visibility.
Public profile:
- /users/:username is now truly public. Renders the user's public
routes + activities, 404s when no public content exists AND viewer
isn't the owner (prevents account enumeration).
- Owner sees a short "this is your profile" note linking to settings.
- Open Graph meta (og:type=profile) for shareable preview.
Privacy manifest:
- Added a bullet noting public content is world-visible on profile
and indexable by search engines.
- Bumped PRIVACY_LAST_UPDATED to 2026-04-20 + rendered legal-archive
snapshot.
Tests:
- 13 unit tests for canView covering the full matrix.
- 6 E2E tests in e2e/public-content.test.ts covering:
- Private route → 404 for logged-out visitor
- Public route → reachable + OG tags present (og:title, og:type,
og:site_name)
- Owner still sees own private content
- Profile 404 when no public content
- Profile renders when at least one public route exists
- Unlisted route reachable via direct URL but hidden from profile
- Test file runs serially (describe.configure mode=serial) to avoid
WebAuthn virtual-authenticator races under Playwright's default
parallel workers.
- New public-content Playwright project added to config.
Rollout safety: every existing row in prod keeps visibility='private'
by default — nothing becomes visible to outsiders until an owner
explicitly opts in.
