894e5e3906 fix: Extract mp-slug before property normalization
Fix bug where custom slugs (mp-slug) were being ignored because they
were extracted from normalized properties after being filtered out.

The root cause: normalize_properties() filters out all mp-* parameters
(line 139) because they're Micropub server extensions, not properties.
The old code tried to extract mp-slug from the normalized properties
dict, but it had already been removed.

The fix: Extract mp-slug directly from raw request data BEFORE calling
normalize_properties(). This preserves the custom slug through to
create_note().

Changes:
- Move mp-slug extraction to before property normalization (line 290-299)
- Handle both form-encoded (list) and JSON (string or list) formats
- Add comprehensive tests for custom slug with both request formats
- All 13 Micropub tests pass

Fixes the issue reported in production where Quill-specified slugs
were being replaced with auto-generated ones.

References:
- docs/reports/custom-slug-bug-diagnosis.md (architect's analysis)
- Micropub spec: mp-slug is a server extension parameter

Database returns notes in DESC order (newest first), but feedgen was
displaying them oldest-first in the RSS XML. Added reversed() wrapper
to maintain correct chronological order in the feed.

Added regression test to verify feed order matches database order.

Bug confirmed by testing:
- Database: [Note 2, Note 1, Note 0] (newest first)
- Old feed: [Note 0, Note 1, Note 2] (oldest first) 
- New feed: [Note 2, Note 1, Note 0] (newest first)

80bd51e4c1 fix: Implement IndieAuth endpoint discovery (v1.0.0-rc.5)
CRITICAL: Fix hardcoded IndieAuth endpoint configuration that violated
the W3C IndieAuth specification. Endpoints are now discovered dynamically
from the user's profile URL as required by the spec.

This combines two critical fixes for v1.0.0-rc.5:
1. Migration race condition fix (previously committed)
2. IndieAuth endpoint discovery (this commit)

## What Changed

### Endpoint Discovery Implementation
- Completely rewrote starpunk/auth_external.py with full endpoint discovery
- Implements W3C IndieAuth specification Section 4.2 (Discovery by Clients)
- Supports HTTP Link headers and HTML link elements for discovery
- Always discovers from ADMIN_ME (single-user V1 assumption)
- Endpoint caching (1 hour TTL) for performance
- Token verification caching (5 minutes TTL)
- Graceful fallback to expired cache on network failures

### Breaking Changes
- REMOVED: TOKEN_ENDPOINT configuration variable
- Endpoints now discovered automatically from ADMIN_ME profile
- ADMIN_ME profile must include IndieAuth link elements or headers
- Deprecation warning shown if TOKEN_ENDPOINT still in environment

### Added
- New dependency: beautifulsoup4>=4.12.0 for HTML parsing
- HTTP Link header parsing (RFC 8288 basic support)
- HTML link element extraction with BeautifulSoup4
- Relative URL resolution against profile URL
- HTTPS enforcement in production (HTTP allowed in debug mode)
- Comprehensive error handling with clear messages
- 35 new tests covering all discovery scenarios

### Security
- Token hashing (SHA-256) for secure caching
- HTTPS required in production, localhost only in debug mode
- URL validation prevents injection
- Fail closed on security errors
- Single-user validation (token must belong to ADMIN_ME)

### Performance
- Cold cache: ~700ms (first request per hour)
- Warm cache: ~2ms (subsequent requests)
- Grace period maintains service during network issues

## Testing
- 536 tests passing (excluding timing-sensitive migration tests)
- 35 new endpoint discovery tests (all passing)
- Zero regressions in existing functionality

## Documentation
- Updated CHANGELOG.md with comprehensive v1.0.0-rc.5 entry
- Implementation report: docs/reports/2025-11-24-v1.0.0-rc.5-implementation.md
- Migration guide: docs/migration/fix-hardcoded-endpoints.md (architect)
- ADR-031: Endpoint Discovery Implementation Details (architect)

## Migration Required
1. Ensure ADMIN_ME profile has IndieAuth link elements
2. Remove TOKEN_ENDPOINT from .env file
3. Restart StarPunk - endpoints discovered automatically

Following:
- ADR-031: Endpoint Discovery Implementation Details
- docs/architecture/endpoint-discovery-answers.md (architect Q&A)
- docs/architecture/indieauth-endpoint-discovery.md (architect guide)
- W3C IndieAuth Specification Section 4.2

44a97e4ffa fix: Change auth blueprint prefix from /admin to /auth (v0.9.2)
The auth routes were registered under /admin/* but the IndieAuth
redirect_uri was configured as /auth/callback, causing 404 errors
when providers redirected back after authentication.

- Change auth blueprint url_prefix from "/admin" to "/auth"
- Update test expectations for new auth route paths
- Add ADR-022 documenting the architectural decision

8be079593f fix: Implement OAuth Client ID Metadata Document endpoint
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%

6a29b0199e Fix IndieAuth client discovery for production authentication
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.
