8352c3ab7c refactor: Rename SCHEMA_SQL to INITIAL_SCHEMA_SQL
This aligns with ADR-033's migration system redesign. The initial schema
represents the v1.0.0 baseline and should not be modified. All schema
changes after v1.0.0 must go in migration files.

Changes:
- Renamed SCHEMA_SQL → INITIAL_SCHEMA_SQL in database.py
- Updated all references in migrations.py comments
- Added comment: "DO NOT MODIFY - This represents the v1.0.0 schema state"
- No functional changes, purely documentation improvement

Part of v1.1.0 migration system redesign (Phase 2).

686d753fb9 fix: Resolve migration race condition with multiple gunicorn workers
CRITICAL PRODUCTION FIX: Implements database-level advisory locking
to prevent race condition when multiple workers start simultaneously.

Changes:
- Add BEGIN IMMEDIATE transaction for migration lock acquisition
- Implement exponential backoff retry (10 attempts, 120s max)
- Add graduated logging (DEBUG -> INFO -> WARNING)
- Create new connection per retry attempt
- Comprehensive error messages with resolution guidance

Technical Details:
- Uses SQLite's native RESERVED lock via BEGIN IMMEDIATE
- 30s timeout per connection attempt
- 120s absolute maximum wait time
- Exponential backoff: 100ms base, doubling each retry, plus jitter
- One worker applies migrations, others wait and verify

Testing:
- All existing migration tests pass (26/26)
- New race condition tests added (20 tests)
- Core retry and logging tests verified (4/4)

Implementation:
- Modified starpunk/migrations.py (+200 lines)
- Updated version to 1.0.0-rc.5
- Updated CHANGELOG.md with release notes
- Created comprehensive test suite
- Created implementation report

Resolves: Migration race condition causing container startup failures
Relates: ADR-022, migration-race-condition-fix-implementation.md
Version: 1.0.0-rc.5

a3bac86647 feat: Complete IndieAuth server removal (Phases 2-4)
Completed all remaining phases of ADR-030 IndieAuth provider removal.
StarPunk no longer acts as an authorization server - all IndieAuth
operations delegated to external providers.

Phase 2 - Remove Token Issuance:
- Deleted /auth/token endpoint
- Removed token_endpoint() function from routes/auth.py
- Deleted tests/test_routes_token.py

Phase 3 - Remove Token Storage:
- Deleted starpunk/tokens.py module entirely
- Created migration 004 to drop tokens and authorization_codes tables
- Deleted tests/test_tokens.py
- Removed all internal token CRUD operations

Phase 4 - External Token Verification:
- Created starpunk/auth_external.py module
- Implemented verify_external_token() for external IndieAuth providers
- Updated Micropub endpoint to use external verification
- Added TOKEN_ENDPOINT configuration
- Updated all Micropub tests to mock external verification
- HTTP timeout protection (5s) for external requests

Additional Changes:
- Created migration 003 to remove code_verifier from auth_state
- Fixed 5 migration tests that referenced obsolete code_verifier column
- Updated 11 Micropub tests for external verification
- Fixed test fixture and app context issues
- All 501 tests passing

Breaking Changes:
- Micropub clients must use external IndieAuth providers
- TOKEN_ENDPOINT configuration now required
- Existing internal tokens invalid (tables dropped)

Migration Impact:
- Simpler codebase: -500 lines of code
- Fewer database tables: -2 tables (tokens, authorization_codes)
- More secure: External providers handle token security
- More maintainable: Less authentication code to maintain

Standards Compliance:
- W3C IndieAuth specification
- OAuth 2.0 Bearer token authentication
- IndieWeb principle: delegate to external services

605681de42 fix: Handle partially migrated databases in migration 002 detection
CRITICAL HOTFIX for production deployment failure

Problem:
- Production database had migration 001 applied but not migration 002
- Migration 002's tables (tokens, authorization_codes) already existed from SCHEMA_SQL
- Smart detection only checked when migration_count == 0 (fresh database)
- For partially migrated databases (count > 0), tried to run full migration
- This failed with "table already exists" error

Solution:
- Always check migration 002's state, regardless of migration_count
- If tables exist with correct structure, skip table creation
- Create missing indexes only
- Mark migration as applied

Testing:
- Manual verification with production scenario: SUCCESS
- 561 automated tests passing
- test_run_migrations_partial_applied confirms fix works

Impact:
- Fixes deployment on partially migrated production databases
- No impact on fresh or fully migrated databases
- Backwards compatible with all database states

Version: 1.0.0-rc.2 → 1.0.0-rc.3

3ed77fd45f fix: Resolve database migration failure on existing databases
Fixes critical issue where migration 002 indexes already existed in SCHEMA_SQL,
causing 'index already exists' errors on databases created before v1.0.0-rc.1.

Changes:
- Removed duplicate index definitions from SCHEMA_SQL (database.py)
- Enhanced migration system to detect and handle indexes properly
- Added comprehensive documentation of the fix

Version bumped to 1.0.0-rc.2 with full changelog entry.

3b41029c75 feat: Implement secure token management for Micropub
Implements token security and management as specified in ADR-029:

Database Changes (BREAKING):
- Add secure tokens table with SHA256 hashed storage
- Add authorization_codes table for IndieAuth token exchange
- Drop old insecure tokens table (invalidates existing tokens)
- Update SCHEMA_SQL to match post-migration state

Token Management (starpunk/tokens.py):
- Generate cryptographically secure tokens
- Hash tokens with SHA256 for secure storage
- Create and verify access tokens
- Create and exchange authorization codes
- PKCE support (optional but recommended)
- Scope validation (V1: only 'create' scope)
- Token expiry and revocation support

Testing:
- Comprehensive test suite for all token operations
- Test authorization code replay protection
- Test PKCE validation
- Test parameter validation
- Test token expiry

Security:
- Tokens never stored in plain text
- Authorization codes single-use with replay protection
- Optional PKCE for enhanced security
- Proper UTC datetime handling for expiry

Following design in ADR-020, implementation guidance, and quick reference.

Phase 1: Migration System Core (starpunk/migrations.py)
- Create migration runner with fresh database detection
- Implement is_schema_current() heuristic for fresh DB detection
- Add helper functions (table_exists, column_exists, index_exists)
- Complete error handling with MigrationError exception
- 315 lines of production code

Phase 2: Database Integration (starpunk/database.py)
- Modify init_db() to call run_migrations()
- Add logger parameter handling
- 5 lines changed for integration

Phase 3: Comprehensive Testing (tests/test_migrations.py)
- 26 tests covering all scenarios (100% pass rate)
- Tests for fresh DB, legacy DB, helpers, error handling
- Integration test with actual migration file
- 560 lines of test code

Phase 4: Version and Documentation
- Bump version to 0.9.0 (MINOR increment per versioning strategy)
- Update CHANGELOG.md with comprehensive v0.9.0 entry
- Create implementation report documenting all details

Features:
- Fresh database detection prevents unnecessary migrations
- Legacy database detection applies pending migrations automatically
- Migration tracking table records all applied migrations
- Idempotent execution safe for multiple runs
- Fail-safe: app won't start if migrations fail
- Container deployments now fully automatic

Testing:
