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.

journal-auth Specification

Purpose

Session management and the terms-of-service consent gate for the Journal app. The credentials a user authenticates with (passkeys, magic links, magic codes) and the registration UX live in authentication-methods; OAuth tokens for third-party services (Wahoo etc.) live in connected-services. This spec is the cross-cutting layer: cookie sessions, the Terms-version gate that wraps every authenticated request, and the rules for safely returning users to where they came from.

Requirements

The Journal SHALL identify signed-in users via a server-set HTTP cookie (__session) that carries a serialized JSON payload containing userId. The cookie SHALL be HttpOnly, SameSite=Lax, signed with the server secret, and have a finite max-age. Anonymous browsers SHALL render the public surface (anonymous home, public profiles, public routes/activities) without a session cookie present.

  • WHEN any authentication path (passkey finish, magic-link verify, code verify) succeeds
  • THEN the response carries a Set-Cookie: __session=... header binding the resulting userId to the browser

Scenario: Anonymous request renders public surface

  • WHEN a request arrives without __session (or with one that fails to verify)
  • THEN loaders treat the request as anonymous; routes that require auth either redirect to /auth/login or render the public layout per their own spec

Requirement: Terms acknowledgement at signup

The registration form SHALL require explicit acknowledgement of the Terms of Service before an account can be created.

Scenario: Checkbox required

  • WHEN a user views the registration form
  • THEN they see a required checkbox labeled "I have read and agree to the Terms of Service, including that trails.cool is in alpha and my data may be reset"
  • AND the checkbox label links to the Terms page

Scenario: Cannot submit without acknowledgement

  • WHEN a user attempts to register without checking the acknowledgement box
  • THEN the form blocks submission and shows a validation message

Scenario: Acknowledgement recorded

  • WHEN a user successfully registers
  • THEN the current timestamp is stored in users.terms_accepted_at
  • AND the version identifier of the Terms the user saw is stored in users.terms_version

Scenario: Missing version rejected

  • WHEN a registration request arrives without a non-empty termsVersion field
  • THEN the server responds with HTTP 400 and does not create a user

Requirement: Re-accept updated Terms on next visit

Logged-in users whose stored terms_version does not match the currently-published version SHALL be prompted to accept the current Terms before accessing any non-allow-listed page.

Scenario: Stale version redirects to accept-terms page

  • WHEN a logged-in user whose users.terms_version is NULL or differs from the current TERMS_VERSION requests any page outside the allow-list (/auth/accept-terms, /auth/logout, /legal/*)
  • THEN the server redirects them to /auth/accept-terms?returnTo=<original path>

Scenario: Allow-list keeps Terms and logout reachable

  • WHEN the same user requests /legal/terms, /legal/privacy, /legal/imprint, /auth/accept-terms, or /auth/logout
  • THEN the request is served normally without being redirected

Scenario: Successful re-acceptance updates both fields

  • WHEN a user submits the acceptance form with the required checkbox ticked
  • THEN the server updates users.terms_version to the current version and users.terms_accepted_at to the current timestamp, then redirects to the returnTo path (or /)
  • WHEN the form is submitted without the checkbox ticked
  • THEN the server responds with HTTP 400 and does not update the user row

Scenario: returnTo is restricted to same-origin paths

  • WHEN a returnTo value is not a same-origin absolute path (missing leading /, or starting with //)
  • THEN the server redirects to / instead, preventing open-redirect abuse
