Ullrich Schäfer 37073eafd7 Spec catchup: drift fixes, account-settings split, notifications archive
Drift (specs aligned to shipped code):
- social-follows: locked-account access rule for /users/:u/followers and
  /users/:u/following (owner + accepted-follower see; non-followers of
  private get 404). Adds the follow→notification lifecycle requirement.
  Fills the placeholder Purpose.
- public-profiles: counts degrade to plain text (not anchors) for viewers
  who can't see the lists. Cross-references social-follows. Fills the
  placeholder Purpose.
- journal-auth slimmed to cookie session + Terms gate. Auth methods moved
  out (see authentication-methods).

Splits:
- account-settings (14-line stub) deleted, content split into:
  - profile-settings (display name, bio, profile_visibility)
  - account-management (email change with verification, account deletion)
  - connected-services (Wahoo + future external integrations)
- authentication-methods split out of journal-auth: passkeys
  (register/login/add/delete), magic links, 6-digit codes
  (login + register), method toggle on register/login forms,
  dev-console fallback.

New specs:
- sse-broker: /api/events, in-process broker, useUnreadNotifications
  hook, Caddy passthrough, multi-process forward-compat contract.

Archived: notifications change → openspec/changes/archive/2026-04-26-notifications.
Promoted the four delta spec files into top-level specs:
- specs/notifications/ (new capability)
- specs/activity-feed/ (added: public activity fan-out)
- specs/journal-landing/ (added: Notifications navbar entry)
- specs/social-follows/ (added: follow→notification lifecycle)

Added openspec/CAPABILITIES.md grouped index covering all 40 specs with
a Conventions section explaining cross-references, naming, and the
catch-up-vs-change rule.

Purpose

Activity creation, chronological feed, detail views, and route linking in the Journal app.

Requirements

Requirement: Create activity

The Journal SHALL allow authenticated users to create an activity by uploading a GPX trace and adding a description.

Scenario: Create activity with GPX

  • WHEN a user uploads a GPX file and enters a description
  • THEN an activity is created with the GPS trace, computed distance and duration, and stored in the database

Scenario: Create activity linked to route

  • WHEN a user creates an activity and selects an existing route
  • THEN the activity is linked to that route (route_id foreign key)

Requirement: Activity feed

The Journal SHALL display a chronological feed of the authenticated user's activities.

Scenario: View own activity feed

  • WHEN a logged-in user navigates to their feed
  • THEN they see their activities in reverse chronological order with name, date, distance, and duration

Requirement: Activity detail page

The Journal SHALL display an activity detail page with map, stats, and description. Access depends on the activity's visibility: public activities are viewable by anyone including unauthenticated visitors, unlisted activities are viewable by anyone who has the URL, and private activities are viewable only by the owner.

Scenario: Owner views own activity

  • WHEN a logged-in user navigates to an activity they own at any visibility
  • THEN they see the activity name, description, a map with the GPS trace, distance, duration, and elevation stats

Scenario: Anyone views a public activity

  • WHEN any visitor (including unauthenticated) navigates to a public activity's URL
  • THEN they see the full activity detail page as above

Scenario: Anyone with the URL views an unlisted activity

  • WHEN any visitor navigates directly to an unlisted activity's URL
  • THEN they see the full activity detail page as above

Scenario: Non-owner is blocked from a private activity

  • WHEN a visitor who is not the owner requests a private activity URL
  • THEN the server responds with HTTP 404 (not 403), so the existence of the private activity is not leaked

Scenario: Public and unlisted activity pages emit social-share metadata

  • WHEN a visitor loads a public or unlisted activity detail page
  • THEN the response emits Open Graph and Twitter Card meta tags (og:title, og:description, og:type="article", og:site_name, twitter:card="summary")

Users SHALL be able to link an existing activity to a route, or create a route from an activity trace.

  • WHEN a user selects "Link to Route" on an activity and chooses a route
  • THEN the activity's route_id is set to the selected route

Scenario: Create route from activity

  • WHEN a user selects "Create Route from Activity"
  • THEN a new route is created using the activity's GPX trace

Requirement: Activity without route

Activities SHALL be allowed to exist without a linked route.

Scenario: Standalone activity

  • WHEN a user imports a GPX activity without linking to a route
  • THEN the activity is stored with route_id as null

Requirement: Instance-wide public activity feed

The Journal SHALL expose a reverse-chronological feed of every activity on the instance with visibility public. This feed powers the instance home page (see journal-landing). private and unlisted activities SHALL NOT appear in this feed; unlisted stays reachable by direct URL only.

Scenario: Public activity appears in the instance feed

  • WHEN an owner marks an activity as public and another visitor loads the home page
  • THEN the visitor sees the activity in the instance feed, with the owner's display name, distance, and start date

Scenario: Private or unlisted activities stay out of the feed

  • WHEN an activity's visibility is private or unlisted
  • THEN it does not appear in the instance feed, regardless of who is viewing

Requirement: Activity visibility

The Journal SHALL persist a visibility value on every activity and SHALL allow the owner to change it.

Scenario: New activities default to private

  • WHEN an activity is created without an explicit visibility
  • THEN the activity row is persisted with visibility = 'private'

Scenario: Owner changes an activity's visibility

  • WHEN an activity owner selects a different visibility (private, unlisted, public) and saves
  • THEN the stored visibility is updated and subsequent access checks use the new value immediately

Requirement: Activity listings respect visibility

The Journal's own-activities feed SHALL show the owner everything regardless of visibility, while any cross-user listing SHALL only include activities with visibility = 'public'.

Scenario: Own activity feed is unchanged

  • WHEN a logged-in user views their own activity feed
  • THEN the feed includes all of their own activities regardless of visibility

Scenario: Public profile lists only public activities

  • WHEN a visitor loads /users/:username
  • THEN the rendered list of activities includes only the user's public activities; unlisted and private activities are omitted

Requirement: Public activity creation fans out notifications

Creating an activity with visibility = 'public' SHALL enqueue a fan-out job that inserts an activity_published notification for every accepted follower of the activity owner. The fan-out SHALL run asynchronously so the activity-creation request returns immediately. See notifications spec for the notification row shape and the idempotency rules.

Scenario: Public activity fans out

  • WHEN a user with N accepted followers creates an activity with visibility = 'public'
  • THEN a pg-boss job is enqueued, and on completion N notifications exist with type = 'activity_published', recipient_user_id ∈ accepted-followers, actor_user_id = activity owner, subject_id = activity id

Scenario: Private or unlisted activity does not fan out

  • WHEN a user creates an activity with visibility = 'private' or 'unlisted'
  • THEN no fan-out job is enqueued and no notifications are created

Scenario: No accepted followers means no notifications

  • WHEN a user with zero accepted followers creates a public activity
  • THEN the fan-out job runs and inserts zero rows
