## Technical Debt
|

Technical debt items are tracked here with a DEBT: prefix. Per project standards, each release must allocate at least 10% of effort to technical debt reduction.
|

|
||||
**Effort to Fix**: 3-5 days (Redis integration, deployment changes)
|
||||
|
||||
**Plan**: Address when scaling beyond single process or when restarts become frequent.
|
||||
|
||||

|
||||
|
||||
### DEBT: Implement schema migrations (S)
|
||||
**Created**: 2025-11-20 (architectural decision)
|
||||
**Priority**: P2
|
||||
|
||||
**Issue**: No formal migration system, using raw SQL files.
|
||||
|
||||
**Impact**: Schema changes require manual intervention.
|
||||
|
||||
**Mitigation (current)**: Simple schema, infrequent changes acceptable for v1.0.0.
|
||||
|
||||
**Effort to Fix**: 1-2 days (Alembic integration)
|
||||
|
||||
**Plan**: Address before v1.1.0 when schema changes become more frequent.

|
||||
## Backlog Management
|
||||
|
||||
### Adding New Features
|
||||
|
||||
When adding features to the backlog:
|
||||
1. Define clear scope and acceptance criteria
|
||||
2. Assign t-shirt size
|
||||
3. Assign priority (P0-P3)
|
||||
4. Identify dependencies
|
||||
5. Estimate effort in days
|
||||
6. Add to appropriate section
|
||||
|
||||
### Prioritization Criteria
|
||||
|
||||
Features are prioritized based on:
|
||||
1. **MVP requirement**: Is it required for v1.0.0?
|
||||
2. **Security impact**: Does it improve security?
|
||||
3. **User value**: How much does it benefit users?
|
||||
4. **Complexity**: Simpler features prioritized when value equal
|
||||
5. **Dependencies**: Features blocking others prioritized
|
||||
|
||||
### Technical Debt Policy
|
||||
|
||||
- Minimum 10% effort per release allocated to technical debt
|
||||
- Technical debt items must have:
|
||||
- Creation date
|
||||
- Issue description
|
||||
- Current impact and mitigation
|
||||
- Effort to fix
|
||||
- Resolution plan
|
||||
- Debt reviewed quarterly, re-prioritized based on impact
|
||||
|
||||
## Version Planning
|
||||
|
||||
See version-specific roadmap files:
|
||||
- `/docs/roadmap/v1.0.0.md` - MVP features and plan
|
||||
- `/docs/roadmap/v1.1.0.md` - First post-MVP release (future)
|
||||
- `/docs/roadmap/v2.0.0.md` - Major feature release (future)
|
||||
|
||||
## Estimation Accuracy
|
||||
|
||||
After each feature implementation, review estimation accuracy:
|
||||
- Compare actual effort vs. estimated
|
||||
- Update t-shirt size if significantly different
|
||||
- Document lessons learned
|
||||
- Adjust future estimates accordingly
|
||||
|
||||
Current estimation baseline: TBD (will be established after v1.0.0 completion)

|
||||
|
||||
**Total Estimated Effort**: 32-44 days of development + testing
|
||||
|
||||
### Explicitly Excluded Features
|
||||
|
||||
These features are intentionally deferred to post-v1.0.0 releases:
|
||||
|
||||
**Excluded (for simplicity)**:
|
||||
- ❌ PKCE support (planned for v1.1.0, see ADR-003)
|
||||
- ❌ Token refresh (planned for v1.1.0)
|
||||
- ❌ Token revocation (planned for v1.1.0)
|
||||
- ❌ Scope-based authorization (planned for v1.2.0)
|
||||
- ❌ Rate limiting (planned for v1.1.0)
|
||||
|
||||
**Excluded (not needed for MVP)**:
|
||||
- ❌ Admin dashboard (planned for v1.2.0)
|
||||
- ❌ Client pre-registration (planned for v1.2.0)
|
||||
- ❌ Alternative auth providers (GitHub/GitLab) (planned for v1.3.0)
|
||||
- ❌ WebAuthn support (planned for v2.0.0)
|
||||
- ❌ PostgreSQL support (planned for v1.2.0)
|
||||
- ❌ Prometheus metrics (planned for v1.1.0)
|
||||
|
||||
**Rationale**: Focus on core authentication functionality with minimal complexity. Additional features add value but increase risk and development time. MVP should prove the concept and gather user feedback.
|
||||
|
||||
## Implementation Plan
|
||||
|
||||
### Phase 1: Foundation (Week 1-2)
|
||||

|
||||
|
||||
**Risks**:
|
||||
- SMTP configuration issues (mitigation: test with real SMTP early)
|
||||
- DNS query timeouts (mitigation: implement retries and fallback)
|
||||
|
||||
**Exit Criteria**:

||||
- Application starts without errors
|
||||
- Health check endpoint returns 200
|
||||
- Email can be sent successfully

|
||||
|
||||
## Risk Assessment
|
||||
|
||||
### High-Risk Areas
|
||||
|
||||
**Email Delivery**:
|
||||
- **Risk**: SMTP configuration issues or delivery failures
|
||||
- **Impact**: Users cannot verify domain ownership
|
||||
- **Mitigation**:
|
||||
- Comprehensive error handling and logging
|
||||
- Test with real SMTP early in development
|
||||
- Provide clear error messages to users
|
||||
- Support TXT record as primary verification method
|
||||
- **Contingency**: Admin can manually verify domains if email fails
|
||||
|
||||
**Security Vulnerabilities**:
|
||||
- **Risk**: Security flaws in authentication/authorization logic
|
||||
- **Impact**: Unauthorized access, data exposure
|
||||
- **Mitigation**:
|
||||
- Follow OAuth 2.0 security best practices
|
||||
- Comprehensive security testing
|
||||
- External security review (recommended)
|
||||
- Conservative defaults
|
||||
- **Contingency**: Rapid patch release if vulnerability found
|
||||
|
||||
**Interoperability**:
|
||||
- **Risk**: Incompatibility with IndieAuth clients
|
||||
- **Impact**: Clients cannot authenticate
|
||||
- **Mitigation**:
|
||||
- Strict W3C spec compliance
|
||||
- Test with multiple clients
|
||||
- Reference implementation comparison
|
||||
- **Contingency**: Fix and patch release
|
||||
|
||||
### Medium-Risk Areas
|
||||
|
||||
**Client Metadata Fetching**:
|
||||
- **Risk**: Timeout or parse failures when fetching client_id
|
||||
- **Impact**: Poor UX (generic client display)
|
||||
- **Mitigation**:
|
||||
- Aggressive timeouts (5 seconds)
|
||||
- Fallback to domain name
|
||||
- Cache successful fetches
|
||||
- **Contingency**: Display warning, continue with basic info
|
||||
|
||||
**DNS Resolution**:
|
||||
- **Risk**: DNS query failures or timeouts
|
||||
- **Impact**: TXT verification unavailable
|
||||
- **Mitigation**:
|
||||
- Multiple resolvers (Google + Cloudflare)
|
||||
- Timeout handling
|
||||
- Fallback to email verification
|
||||
- **Contingency**: Email verification as alternative
|
||||
|
||||
**Database Performance**:
|
||||
- **Risk**: SQLite performance degrades with usage
|
||||
- **Impact**: Slow response times
|
||||
- **Mitigation**:
|
||||
- Indexes on critical columns
|
||||
- Periodic cleanup of expired tokens
|
||||
- Benchmark under load
|
||||
- **Contingency**: Migrate to PostgreSQL if needed (already supported by SQLAlchemy)
|
||||
|
||||
### Low-Risk Areas
|
||||
|
||||
**Deployment**:
|
||||
- **Risk**: Docker issues or configuration errors
|
||||
- **Impact**: Cannot deploy
|
||||
- **Mitigation**: Test deployment early, document thoroughly
|
||||
|
||||
**UI/UX**:
|
||||
- **Risk**: Forms confusing or inaccessible
|
||||
- **Impact**: User frustration
|
||||
- **Mitigation**: Keep forms simple, test accessibility

## Success Metrics
|
||||
|
||||
### Release Success
|
||||
|
||||
The v1.0.0 release is successful if:
|
||||
|
||||
1. **Functional**: At least one real-world user successfully authenticates
|
||||
2. **Quality**: No critical bugs reported in first week
|
||||
3. **Security**: No security vulnerabilities reported in first month
|
||||
4. **Operational**: Server runs stably for 1 week without restarts
|
||||
5. **Compliance**: Successfully interoperates with ≥2 different IndieAuth clients
|
||||
|
||||
### User Success
|
||||
|
||||
Users are successful if:
|
||||
|
||||
1. Can verify domain ownership (either method) in <5 minutes
|
||||
2. Can complete authentication flow in <2 minutes
|
||||
3. Understand what is happening at each step
|
||||
4. Feel secure about the process
|
||||

|
||||
2. No major scope changes during development
|
||||
3. Test coverage goals met

## Budget
|
||||
|
||||
**Total Estimated Effort**: 32-44 days of development + 10-14 days of testing (parallel)
|
||||
|
||||
**Breakdown**:
|
||||
- Phase 1 (Foundation): 7-11 days
|
||||
- Phase 2 (Domain Verification): 4-7 days
|
||||
- Phase 3 (IndieAuth Protocol): 6-9 days
|
||||
- Phase 4 (Security): 3-5 days
|
||||
- Phase 5 (Deployment & Testing): 5-8 days
|
||||
- Testing (parallel throughout): 10-14 days
|
||||
|
||||
**Technical Debt Allocation**: 10% = 4-5 days
|
||||
- Schema migration prep
|
||||
- Redis integration groundwork
|
||||
- Documentation improvements
|
||||
|
||||
**Total Timeline**: 6-8 weeks (assuming 1 developer, ~5 days/week)
