Separation of Concerns +Authentication routes (`/auth/*`) should be semantically separate from administration routes (`/admin/*`). This creates a cleaner architecture where: +- `/auth/*` handles authentication flows (login, callback, logout) +- `/admin/*` handles protected administrative functions (dashboard, CRUD operations) + +### 2. Standards Compliance +IndieAuth and OAuth2 conventions typically use `/auth/callback` for OAuth callbacks: +- Most OAuth documentation and examples use this pattern +- IndieAuth implementations commonly expect callbacks at `/auth/callback` +- Follows RESTful URL design principles + +### 3. Security Benefits +Clear separation provides: +- Easier application of different security policies (rate limiting on auth vs admin) +- Clearer audit trails and access logs +- Reduced cognitive load when reviewing security configurations +- Better principle of least privilege implementation + +### 4. Minimal Impact +Analysis of the codebase shows: +- No hardcoded URLs to `/admin/login` in external-facing documentation +- All internal redirects use `url_for('auth.login_form')` which will automatically adjust +- Templates use named routes: `url_for('auth.login_initiate')`, `url_for('auth.logout')` +- No stored auth_state data is tied to the URL path + +### 5. Future Flexibility +If we later need public authentication for other features: +- API token generation could live at `/auth/tokens` +- OAuth provider functionality could use `/auth/authorize` +- WebAuthn endpoints could use `/auth/webauthn` +- All auth-related functionality stays organized under `/auth` + +## Consequences + +### Positive +- **Fixes the immediate bug**: IndieAuth callbacks will work correctly +- **Cleaner architecture**: Proper separation between auth and admin concerns +- **Standards alignment**: Matches common OAuth/IndieAuth patterns +- **No breaking changes**: All internal routes use named endpoints +- **Better organization**: More intuitive URL structure + +### Negative +- **Documentation updates needed**: Must update docs showing `/admin/login` paths +- **Potential user confusion**: Users who bookmarked `/admin/login` will get 404 + - Mitigation: Could add a redirect from `/admin/login` to `/auth/login` for transition period + +### Migration Requirements +- No database migrations required +- No session invalidation needed +- No configuration changes needed +- Simply update the blueprint registration + +## Alternatives Considered + +### Alternative 1: Change redirect_uri to `/admin/callback` +**Rejected because:** +- Mixes authentication concerns with administration in URL structure +- Goes against common OAuth/IndieAuth URL patterns +- Less intuitive - callbacks aren't "admin" functions +- Requires changes in two places in `auth.py` (lines 325 and 414) + +### Alternative 2: Create a separate `/auth` blueprint just for callback +**Rejected because:** +- Splits related authentication logic across multiple blueprints +- More complex routing configuration +- Harder to maintain - auth logic spread across files +- Violates single responsibility principle at module level + +### Alternative 3: Use root-level routes (`/login`, `/callback`, `/logout`) +**Rejected because:** +- Pollutes the root namespace +- No logical grouping of related routes +- Harder to apply auth-specific middleware +- Less scalable as application grows + +### Alternative 4: Keep current structure and add redirect +**Rejected because:** +- Doesn't fix the underlying architectural issue +- Adds unnecessary HTTP redirect overhead +- Makes debugging more complex +- Band-aid solution rather than proper fix + +## Implementation + +### Required Change +Update line 30 in `/home/phil/Projects/starpunk/starpunk/routes/auth.py`: +```python +# From: +bp = Blueprint("auth", __name__, url_prefix="/admin") + +# To: +bp = Blueprint("auth", __name__, url_prefix="/auth") +``` + +### Results +This single change will: +- Make the callback available at `/auth/callback` (matching the redirect_uri) +- Move login to `/auth/login` +- Move logout to `/auth/logout` +- All template references using `url_for()` will automatically resolve correctly + +### Optional Transition Support +If desired, add temporary redirects in `starpunk/routes/admin.py`: +```python +@bp.route("/login") +def old_login_redirect(): + """Temporary redirect for bookmarks""" + return redirect(url_for("auth.login_form"), 301) +``` + +### Documentation Updates Required +Files to update: +- `/home/phil/Projects/starpunk/TECHNOLOGY-STACK-SUMMARY.md` - Update route table +- `/home/phil/Projects/starpunk/docs/design/phase-4-web-interface.md` - Update route documentation +- `/home/phil/Projects/starpunk/docs/designs/phase-5-quick-reference.md` - Update admin access instructions + +## Testing Verification +After implementation: +1.
