This fixes critical IndieAuth authentication by implementing PKCE (Proof Key
for Code Exchange) as required by IndieLogin.com API specification.
Added:
- PKCE code_verifier and code_challenge generation (RFC 7636)
- Database column: auth_state.code_verifier for PKCE support
- Issuer validation for authentication callbacks
- Comprehensive PKCE unit tests (6 tests, all passing)
- Database migration script for code_verifier column
Changed:
- Corrected IndieLogin.com API endpoints (/authorize and /token)
- State token validation now returns code_verifier for token exchange
- Authentication flow follows IndieLogin.com API specification exactly
- Enhanced logging with code_verifier redaction
Removed:
- OAuth metadata endpoint (/.well-known/oauth-authorization-server)
Added in v0.7.0 but not required by IndieLogin.com
- h-app microformats markup from templates
Modified in v0.7.1 but not used by IndieLogin.com
- indieauth-metadata link from HTML head
Security:
- PKCE prevents authorization code interception attacks
- Issuer validation prevents token substitution attacks
- Code verifier securely stored, redacted in logs, and single-use
Documentation:
- Version: 0.8.0
- CHANGELOG updated with v0.8.0 entry and v0.7.x notes
- ADR-016 and ADR-017 marked as superseded by ADR-019
- Implementation report created in docs/reports/
- Test update guide created in TODO_TEST_UPDATES.md
Breaking Changes:
- Users mid-authentication will need to restart login after upgrade
- Database migration required before deployment

Fixes critical IndieAuth authentication failure by implementing modern
JSON-based client discovery mechanism per IndieAuth spec section 4.2.
Added /.well-known/oauth-authorization-server endpoint returning JSON
metadata with client_id, redirect_uris, and OAuth capabilities.
Added <link rel="indieauth-metadata"> discovery hint in HTML head.
Maintained h-app microformats for backward compatibility with legacy
IndieAuth servers.
This resolves "client_id is not registered" error from IndieLogin.com
by providing the metadata document modern IndieAuth servers expect.
Changes:
- Added oauth_client_metadata() endpoint in public routes
- Returns JSON with client info (24-hour cache)
- Uses config values (SITE_URL, SITE_NAME) not hardcoded URLs
- Added indieauth-metadata link in base.html
- Comprehensive test suite (15 new tests, all passing)
- Updated version to v0.6.2 (PATCH increment)
- Updated CHANGELOG.md with detailed fix documentation
Standards Compliance:
- IndieAuth specification section 4.2
- OAuth Client ID Metadata Document format
- IANA well-known URI registry
- RFC 7591 OAuth 2.0 Dynamic Client Registration
Testing:
- 467/468 tests passing (99.79%)
- 15 new tests for OAuth metadata and discovery
- Zero regressions in existing tests
- Test coverage maintained at 88%

Architect analysis identified the root cause of 'client_id is not
registered' error: h-app microformat is hidden from parsers.
Includes:
- Complete diagnosis of IndieAuth client registration issue
- ADR-006: IndieAuth Client Identification decision record
- Implementation guidelines for developer
Developer task: Remove hidden attributes from h-app div.

Add minimal, production-ready static HTML identity page as reference
implementation for IndieAuth authentication.
Includes:
- Complete identity-page.html with h-card and IndieAuth endpoints
- Architectural documentation and rationale
- ADR-010: Static Identity Page decision record
- Customization guide for users
The example is zero-dependency, copy-paste ready, and guaranteed to
work with IndieLogin.com and StarPunk. Pre-configured for
thesatelliteoflove.com as working example.

Add h-app microformats markup to base.html to enable IndieLogin.com
to verify StarPunk as a legitimate OAuth client. Without this markup,
IndieLogin returns "client_id is not registered" error, blocking all
production authentication.
The h-app markup provides client identification per IndieAuth legacy
standard, which is widely supported by authorization servers including
IndieLogin.com.
Changes:
- Add h-app microformats div to base.html footer (hidden)
- Update version to v0.6.1 (patch release per ADR-008)
- Update CHANGELOG.md with v0.6.1 release notes
- Add 6 comprehensive tests for h-app markup (all passing)
- Create ADR-016 documenting client discovery decision
- Create architecture analysis report
- Create implementation report
Tests: 456 total, 455 passing (99.78%)
New tests: 6 for h-app microformats (100% passing)
Fixes critical bug preventing production authentication.
