Existing Codebase Review

Current State (v0.4.0 - Phase 3 complete):

Modules Implemented:

starpunk/
├── __init__.py          # Package initialization, version
├── auth.py              # Authentication (433 lines, 96% coverage)
├── config.py            # Configuration management
├── database.py          # Database connection, schema
├── models.py            # Data models (Note, Session)
├── notes.py             # Note management (create, read, update, delete)
└── utils.py             # Utilities (slug, hash, file ops)

Authentication Capabilities (from auth.py review):

• initiate_login(me_url) - Start IndieLogin flow
• handle_callback(code, state) - Process callback
• create_session(me) - Create authenticated session
• verify_session(token) - Validate session
• destroy_session(token) - Logout
• require_auth decorator - Protect routes

Integration Points Available:

1. Flask Integration: Uses g, current_app, request, session
2. Database Integration: Uses get_db() from database.py
3. Notes Integration: Can call notes.py functions
4. Utils Integration: Can use slug generation, file ops

What Phase 4 Adds:

• Route handlers (public, admin, auth)
• Templates (Jinja2)
• Static assets (CSS, optional JS)
• Development authentication module
• Configuration validation

Architectural Fit: Phase 4 is the presentation layer on top of solid business logic foundation.

Critical Architectural Question: Development Authentication

The Question

Should we build a development authentication mechanism to allow for local testing when IndieLogin.com is not available?

My Answer: YES, with Strict Safeguards

Decision: Implement a development authentication mechanism that:

1. Only activates when explicitly configured (DEV_MODE=true)
2. Uses separate routes from production (/dev/login vs /admin/login)
3. Cannot coexist with production configuration
4. Logs prominent warnings when active
5. Returns 404 for dev routes when disabled
6. Requires explicit environment variable opt-in

Rationale

Development Pain Points Without Dev Auth:

• Cannot test protected routes locally
• Must deploy to cloud for every auth test
• Cannot run integration tests without network
• Cannot develop offline
• Slow iteration cycle (minutes vs seconds)
• Painful onboarding for new developers

Benefits of Dev Auth:

• Development Velocity: 10/10 - Instant local testing
• Developer Experience: 10/10 - Remove deployment friction
• Testing: 10/10 - Enable comprehensive test coverage
• CI/CD: 10/10 - Fast, deterministic tests

Security Concerns Addressed:

• Separate Routes: Dev auth at /dev/login, production at /admin/login
• Explicit Configuration: Requires DEV_MODE=true in .env
• Cannot Coexist: Config validation prevents DEV_MODE + production SITE_URL
• Route Protection: Dev routes return 404 if DEV_MODE=false
• Visual Warnings: Prominent banner in UI when dev mode active
• Logging: All dev auth usage logged with warnings
• Module Separation: dev_auth.py separate from production auth.py

Why This Approach:

• Explicit > Implicit (no localhost detection)
• Separation > Modification (new routes, not changing existing)
• Fail-Safe > Fail-Open (404 if not explicitly enabled)
• Visible > Hidden (warnings in logs and UI)

Alternatives Rejected:

1. No dev auth - Too much friction
2. Mock-only - Doesn't help UI testing
3. Localhost detection - Too implicit, dangerous
4. Special password - Defeats IndieWeb principles
5. Self-hosted IndieAuth - Too complex for V1

See ADR-011 for complete analysis.

Phase 4 Design Overview

Scope

Public Interface (No Authentication):

• Homepage (/) - Recent published notes
• Note Permalink (/note/<slug>) - Individual note
• Microformats2 markup (h-feed, h-entry)

Admin Interface (Authentication Required):

• Login (/admin/login) - IndieLogin flow
• Dashboard (/admin) - Note list with edit/delete
• Create Note (/admin/new) - Form for new notes
• Edit Note (/admin/edit/<id>) - Edit existing
• Logout - Destroy session

Development Interface (DEV_MODE Only):

• Dev Login (/dev/login) - Instant auth for testing

Architecture

Layers:

Presentation Layer (NEW)
  ├── Routes (public, admin, auth, dev_auth)
  ├── Templates (Jinja2)
  └── Static Assets (CSS, optional JS)
         ↓
Business Logic Layer (EXISTING)
  ├── auth.py (Phase 3)
  ├── notes.py (Phase 2)
  └── utils.py (Phase 1)
         ↓
Data Layer (EXISTING)
  ├── Markdown Files
  └── SQLite Database

Clean Separation: Web interface is pure presentation layer consuming existing business logic.

Route Structure

Public Routes (no auth):

GET  /              → index()          → templates/index.html
GET  /note/<slug>   → note(slug)       → templates/note.html

Auth Routes:

GET  /admin/login   → login_form()     → templates/admin/login.html
POST /admin/login   → login_initiate() → Redirect to IndieLogin
GET  /auth/callback → callback()       → Redirect to /admin (with session)
POST /admin/logout  → logout()         → Redirect to /

Admin Routes (auth required):

GET  /admin              → dashboard()        → templates/admin/dashboard.html
GET  /admin/new          → new_note_form()    → templates/admin/new.html
POST /admin/new          → create_note()      → Redirect to /admin
GET  /admin/edit/<id>    → edit_note_form()   → templates/admin/edit.html
POST /admin/edit/<id>    → update_note()      → Redirect to /admin
POST /admin/delete/<id>  → delete_note()      → Redirect to /admin

Dev Routes (DEV_MODE only):

GET  /dev/login     → dev_login()      → Redirect to /admin (instant session)

Template Architecture

Base Templates:

• templates/base.html - Public layout
• templates/admin/base.html - Admin layout (extends base)

Public Templates:

• templates/index.html - Homepage (h-feed)
• templates/note.html - Note permalink (h-entry)

Admin Templates:

• templates/admin/login.html - Login form
• templates/admin/dashboard.html - Note list
• templates/admin/new.html - Create note
• templates/admin/edit.html - Edit note

Features:

• Microformats2 markup
• Flash message support
• Dev mode warnings (when active)
• Mobile responsive
• Semantic HTML5

CSS Architecture

File: static/css/style.css (~300-400 lines)

Structure:

/* Variables */
:root { --color-text, --font-body, --spacing, etc. }

/* Reset & Base */
* { box-sizing, margin, padding }

/* Typography */
h1, h2, p, a, code

/* Layout */
header, main, footer, max-width

/* Components */
.h-entry, .flash, .button, .form-group

/* Dev Warning */
.dev-mode-warning { background: red; }

/* Responsive */
@media (min-width: 768px) { ... }

Philosophy:

• Mobile-first
• CSS custom properties for theming
• No framework
• Semantic class names
• ~300-400 lines total

JavaScript (Optional)

File: static/js/preview.js

Purpose: Live markdown preview in admin editor

Implementation:

• Progressive enhancement (works without JS)
• Uses marked.js from CDN
• Debounced input handler (300ms)
• Only loads on admin pages

Graceful Degradation: Core functionality works without JavaScript.

Security Architecture

Authentication Security

Production (IndieLogin):

• Full OAuth 2.0 flow
• CSRF state tokens (5-min expiry)
• Session tokens (30-day expiry)
• HttpOnly, Secure, SameSite cookies
• Single admin user (ADMIN_ME validation)

Development (DEV_MODE):

• Separate routes (/dev/login)
• Explicit configuration required
• Returns 404 if disabled
• Prominent warnings
• Cannot coexist with production config

Route Protection:

• All /admin/* routes use @require_auth
• Public routes no authentication
• Dev routes conditionally registered

Input Security

User Input:

• Markdown: No special validation (markdown is safe)
• Forms: Flask form validation
• Slugs: Validated by utils module
• URLs: Validated by auth module

XSS Prevention:

• Jinja2 auto-escaping enabled
• No user-generated HTML accepted
• Markdown rendered server-side
• No |safe except for known-safe content

CSRF Protection:

• State tokens for auth flow
• SameSite=Lax cookies
• POST for state-changing operations

Configuration Security

Validation on Startup:

if DEV_MODE:
    if not DEV_ADMIN_ME:
        raise ConfigError()
    if SITE_URL.startswith('https://'):
        logger.error("WARNING: DEV_MODE with production URL")
else:
    if not ADMIN_ME:
        raise ConfigError()

Fail-Safe Design:

• Dev routes return 404 unless explicitly enabled
• No way to accidentally enable in production
• Visual warnings if misconfigured

---

Testing Strategy

• Test logout

tests/test_dev_auth.py:

• Test dev login creates session
• Test dev routes return 404 when disabled
• Test configuration validation
• Test dev mode indicators
• Test production mode blocks dev routes

Integration Tests

• Full auth flow (mocked IndieLogin)

Optimizations

Database:

• Indexes on notes.created_at (already exists)
• Single query per page
• Efficient pagination (LIMIT/OFFSET)

Templates:

• Simple templates (fast rendering)
• Minimal template inheritance
• No expensive template filters

Static Assets:

• Single CSS file (one request)
• Optional JS (non-blocking)
• Browser caching headers

Markdown Rendering:

• Already implemented in notes module
• Efficient Python markdown library
