+
+You are an elite Documentation Architect with expertise in information architecture, technical writing standards, and repository organization. You maintain documentation systems for enterprise software projects and ensure they remain maintainable, discoverable, and aligned with industry best practices.
+
+Your primary responsibilities:
+
+1. REPOSITORY ROOT CURATION:
+- The repository root must ONLY contain: README.md, CLAUDE.md, and CHANGELOG.md
+- Immediately identify and relocate any other documentation files to appropriate docs/ subdirectories
+- Maintain this standard vigilantly - a clean root is critical for repository professionalism
+
+2. README.md MANAGEMENT:
+- Collaborate with the architect agent to ensure README.md is comprehensive and current
+- README.md must contain everything needed for deployment and usage:
+  * Clear project description and purpose
+  * Installation instructions (note: this project uses uv for Python venv management)
+  * Configuration requirements
+  * Usage examples
+  * API documentation or links to detailed docs
+  * Troubleshooting guidance
+  * Contributing guidelines
+  * License information
+- Review README.md after any significant feature changes
+- Ensure technical accuracy by consulting with the architect when needed
+
+3. DOCS/ FOLDER STRUCTURE:
+Maintain strict organization:
+- architecture/ - Architectural documentation, system design overviews, component diagrams
+- decisions/ - Architectural Decision Records (ADRs) documenting significant decisions
+- designs/ - Detailed design documents for features and components
+- standards/ - Coding standards, conventions, best practices, style guides
+- reports/ - Implementation reports created by developers for architect review
+
+4. DOCUMENT CLASSIFICATION AND SPLITTING:
+- Proactively identify documents containing multiple types of information
+- When a document contains mixed content types (e.g., a decision with embedded standards):
+  * Collaborate with the architect agent to split the document
+  * Ensure each resulting document is focused and single-purpose
+  * Example: If ADR-015 contains both decision rationale and coding standards, split into:
+    - decisions/ADR-015-database-schema-decision.md (decision only)
+    - standards/database-migration-standards.md (extracted standards)
+- Maintain cross-references between related split documents
+
+5. QUALITY STANDARDS:
+- Ensure all documentation follows markdown best practices
+- Verify consistent formatting, heading structure, and link validity
+- Check that file naming conventions are clear and consistent (kebab-case preferred)
+- Validate that documentation is dated and versioned where appropriate
+- Ensure ADRs follow standard ADR format (Context, Decision, Consequences)
+
+6. PROACTIVE MAINTENANCE:
+- Regularly audit docs/ folder for misplaced files
+- Identify documentation that has become outdated or redundant
+- Flag documentation gaps when new features lack adequate documentation
+- Recommend documentation improvements to the architect
+
+7. COLLABORATION PROTOCOL:
+- Work closely with the architect agent on README.md updates
+- Consult the architect when document splitting decisions are complex
+- Coordinate with developers to ensure reports/ folder is reviewed by architect
+- When uncertain about document classification, consult with the architect
+
+Your workflow:
+1. Assess the current state of repository documentation
+2. Identify issues: misplaced files, outdated content, missing documentation, multi-purpose documents
+3. For simple relocations and updates, execute immediately
+4. For complex decisions (splitting documents, significant README changes), collaborate with the architect
+5. After changes, verify the repository maintains proper structure
+6. Document your actions clearly in your responses
+
+Key principles:
+- Maintainability over comprehensiveness - well-organized simple docs beat sprawling complex ones
+- Discoverability - users should find what they need quickly
+- Single source of truth - avoid documentation duplication
+- Living documentation - docs should evolve with the codebase
+- Clear separation of concerns - each document type serves a distinct purpose
+
+When you identify issues, be specific about what's wrong and what needs to change. When proposing splits or major reorganizations, explain your reasoning clearly. Always prioritize the end user's ability to quickly find and understand the information they need.

+### Notes
+This is a release candidate for testing. Stable 1.0.0 will be released after testing period and any necessary fixes.
+
+## [0.9.5] - 2025-11-23
+
+### Fixed
+- **SECRET_KEY empty string handling**: Fixed config.py to properly handle empty `FLASK_SECRET_KEY` environment variable
+  - `os.getenv()` returns empty string (not None) when env var is set to `""`
+  - Empty string now correctly falls back to SESSION_SECRET
+  - Prevents Flask session/flash failures when FLASK_SECRET_KEY="" in .env file
+
+## [0.9.4] - 2025-11-22
+
+### Fixed
+- **IndieAuth authentication endpoint correction**: Changed code redemption from token endpoint to authorization endpoint
+  - Per IndieAuth spec: authentication-only flows use `/authorize`, not `/token`
+  - StarPunk only needs identity verification, not access tokens
+  - Removed unnecessary `grant_type` parameter (only needed for token endpoint)
+  - Updated debug logging to reflect "code verification" terminology
+  - Fixes authentication with IndieLogin.com and spec-compliant providers
+
+### Changed
+- Code redemption now POSTs to `/authorize` endpoint instead of `/token`
+- Log messages updated from "token exchange" to "code verification"
+
+## [0.9.3] - 2025-11-22
+
+### Fixed
+- **IndieAuth token exchange missing grant_type**: Added required `grant_type=authorization_code` parameter to token exchange request
+  - OAuth 2.0 spec requires this parameter for authorization code flow
+  - Some IndieAuth providers reject token exchange without this parameter
+  - Fixes authentication failures with spec-compliant IndieAuth providers

+# Claude Agent Instructions
+
+This file contains operational instructions for Claude agents working on this project.
+
+## Python Environment
+
+- We use **uv** for Python virtual environment management
+- All Python commands must be run with `uv run` prefix
+- Example: `uv run pytest`, `uv run flask run`
+
+## Agent-Architect Protocol
+
+When invoking the agent-architect, always remind it to:
+
+1. Review documentation in docs/ before working on the task it is given 
+   - docs/architecture, docs/decisions, docs/standards are of particular interest 
+
+2. Give it the map of the documentation folder as described in the "Understanding the docs/ Structure" section below
+
+3. Search for authoritative documentation for any web standard it is implementing on https://www.w3.org/
+
+4. If it is reviewing a developers implementation report and it is accepts the completed work it should go back and update the project plan to reflect the completed work
+
+## Agent-Developer Protocol
+
+When invoking the agent-developer, always remind it to:
+
+1. **Document work in reports**
+   - Create implementation reports in `docs/reports/`
+   - Include date in filename: `YYYY-MM-DD-description.md`
+
+2. **Update the changelog**
+   - Add entries to `CHANGELOG.md` for user-facing changes
+   - Follow existing format
+
+3. **Version number management**
+   - Increment version numbers according to `docs/standards/versioning-strategy.md`
+   - Update version in `starpunk/__init__.py`

+**Admin Auth**: IndieLogin.com OAuth 2.0 flow with PKCE
+**Status**: ✅ IMPLEMENTED (v0.8.0, refined through v0.9.5)

+1. User enters website URL (their "me" identity)
+2. Generate PKCE code_verifier and code_challenge (SHA-256)
+3. Store state token + code_verifier in database (5 min expiry)
+4. Redirect to indielogin.com/authorize with:
+   - client_id (SITE_URL with trailing slash)

+- State tokens prevent CSRF attacks
+- Session token hashing (SHA-256) before database storage
+- Single-use state tokens with short expiry
+- Automatic trailing slash normalization on SITE_URL (v0.9.1)
+- Uses authorization endpoint (not token endpoint) per IndieAuth spec (v0.9.4)
+- Session cookie renamed to avoid Flask session collision (v0.5.1)

+# ADR-021: IndieAuth Provider Strategy
+
+## Status
+Accepted
+
+## Context
+
+StarPunk currently uses IndieLogin.com for authentication (ADR-005), but there is a critical misunderstanding about how IndieAuth works that needs to be addressed.
+
+### The Problem
+
+The user reported that IndieLogin.com requires manual client_id registration, making it unsuitable for self-hosted software where each installation has a different domain. This concern is based on a fundamental misunderstanding of how IndieAuth differs from traditional OAuth2.
+
+### How IndieAuth Actually Works
+
+Unlike traditional OAuth2 providers (GitHub, Google, etc.), **IndieAuth does not require pre-registration**:
+
+1. **DNS-Based Client Identification**: IndieAuth uses DNS as a replacement for client registration. A client application identifies itself using its own URL (e.g., `https://starpunk.example.com`), which serves as a unique identifier.
+
+2. **No Secrets Required**: All clients are public clients. There are no client secrets to manage or register.
+
+3. **Dynamic Redirect URI Verification**: Instead of pre-registered redirect URIs, applications publish their valid redirect URLs at their client_id URL, which authorization servers can discover.
+
+4. **Client Metadata Discovery**: Authorization servers can optionally fetch the client_id URL to display application information (name, logo) to users during authorization.
+
+### StarPunk's Authentication Architecture
+
+It is critical to understand that StarPunk has **two distinct authentication flows**:
+
+#### Flow 1: Admin Authentication (Current Misunderstanding)
+**Purpose**: Authenticate the StarPunk admin user to access the admin interface
+**Current Implementation**: Uses IndieLogin.com as described in ADR-005
+**How it works**:
+1. Admin visits `/admin/login`
+2. StarPunk redirects to IndieLogin.com with its own URL as `client_id`
+3. IndieLogin.com verifies the admin's identity
+4. Admin receives session cookie to access StarPunk admin
+
+**Registration Required?** NO - IndieAuth never requires registration
+
+#### Flow 2: Micropub Client Authorization (The Real Architecture)
+**Purpose**: Allow external Micropub clients to publish to StarPunk
+**How it works**:
+1. User configures their personal website (e.g., `https://alice.com`) with links to StarPunk's Micropub endpoint
+2. User opens Micropub client (Quill, Indigenous, etc.)
+3. Client discovers authorization/token endpoints from `https://alice.com` (NOT from StarPunk)
+4. Client gets access token from the discovered authorization server
+5. Client uses token to POST to StarPunk's Micropub endpoint
+6. StarPunk verifies the token
+
+**Who Provides Authorization?** The USER's chosen authorization server, not StarPunk
+
+### The Real Question
+
+StarPunk faces two architectural decisions:
+
+1. **Admin Authentication**: How should StarPunk administrators authenticate to the admin interface?
+2. **User Authorization**: Should StarPunk provide authorization/token endpoints for its users, or should users bring their own?
+
+## Research Findings
+
+### Alternative IndieAuth Services
+
+**IndieLogin.com** (Current)
+- Actively maintained by Aaron Parecki (IndieAuth spec editor)
+- Supports multiple auth methods: RelMeAuth, email, PGP, BlueSky OAuth (added 2025)
+- **No registration required** - this was the key misunderstanding
+- Free, community service
+- High availability
+
+**tokens.indieauth.com**
+- Provides token endpoint functionality
+- Separate from authorization endpoint
+- Also maintained by IndieWeb community
+- Also requires no registration
+
+**Other Services**
+- No other widely-used public IndieAuth providers found
+- Most implementations are self-hosted (see below)
+
+### Self-Hosted IndieAuth Implementations
+
+**Taproot/IndieAuth** (PHP)
+- Complexity: Moderate (7/10)
+- Full-featured: Authorization + token endpoints
+- PSR-7 compatible, well-tested (100% coverage)
+- Lightweight dependencies (Guzzle, mf2)
+- Production-ready since v0.1.0
+
+**Selfauth** (PHP)
+- Complexity: Low (3/10)
+- **Limitation**: Authorization endpoint ONLY (no token endpoint)
+- Cannot be used for Micropub (requires token endpoint)
+- Suitable only for simple authentication use cases
+
+**hacdias/indieauth** (Go)
+- Complexity: Moderate (6/10)
+- Provides both server and client libraries
+- Modern Go implementation
+- Used in production by author
+
+**Custom Implementation** (Python)
+- Complexity: High (8/10)
+- Must implement IndieAuth spec 1.1
+- Required endpoints:
+  - Authorization endpoint (authentication + code generation)
+  - Token endpoint (token issuance + verification)
+  - Metadata endpoint (server discovery)
+  - Introspection endpoint (token verification)
+- Must support:
+  - PKCE (required by spec)
+  - Client metadata discovery
+  - Profile URL validation
+  - Scope-based permissions
+  - Token revocation
+- Estimated effort: 40-60 hours for full implementation
+- Ongoing maintenance burden for security updates
+
+## Decision
+
+**Recommendation: Continue Using IndieLogin.com with Clarified Architecture**
+
+StarPunk should:
+
+1. **For Admin Authentication**: Continue using IndieLogin.com (no changes needed)
+   - No registration required
+   - Works out of the box for self-hosted installations
+   - Each StarPunk instance uses its own domain as client_id
+   - Zero maintenance burden
+
+2. **For Micropub Authorization**: Document that users must provide their own authorization server
+   - User configures their personal domain with IndieAuth endpoints
+   - User can choose:
+     - IndieLogin.com (easiest)
+     - Self-hosted IndieAuth server (advanced)
+     - Any other IndieAuth-compliant service
+   - StarPunk only verifies tokens, doesn't issue them
+
+3. **For V2 Consideration**: Optionally provide built-in authorization server
+   - Would allow StarPunk to be a complete standalone solution
+   - Users could use StarPunk's domain as their identity
+   - Requires implementing full IndieAuth server (40-60 hours)
+   - Only pursue if there is strong user demand
+
+## Rationale
+
+### Why Continue with IndieLogin.com
+
+**Simplicity Score: 10/10**
+- Zero configuration required
+- No registration process
+- Works immediately for any domain
+- Battle-tested by IndieWeb community
+- The original concern (manual registration) does not exist
+
+**Fitness Score: 10/10**
+- Perfect for single-user CMS
+- Aligns with IndieWeb principles
+- User controls their identity
+- No lock-in (user can switch authorization servers)
+
+**Maintenance Score: 10/10**
+- Externally maintained
+- Security updates handled by community
+- No code to maintain in StarPunk
+- Proven reliability and uptime
+
+**Standards Compliance: Pass**
+- Full IndieAuth spec compliance
+- OAuth 2.0 compatible
+- Supports modern extensions (PKCE, client metadata)
+
+### Why Not Self-Host (for V1)
+
+**Complexity vs Benefit**
+- Self-hosting adds 40-60 hours of development
+- Ongoing security maintenance burden
+- Solves a problem that doesn't exist (no registration required)
+- Violates "every line of code must justify its existence"
+
+**User Perspective**
+- Users already need a domain for IndieWeb
+- Most users will use IndieLogin.com or similar service
+- Advanced users can self-host their own IndieAuth server
+- StarPunk doesn't need to solve this problem
+
+**Alternative Philosophy**
+- StarPunk is a Micropub SERVER, not an authorization server
+- Separation of concerns: publishing vs identity
+- Users should control their own identity infrastructure
+- StarPunk focuses on doing one thing well: publishing notes

+
+### What StarPunk Implements
+
+**Currently Implemented** (ADR-005):
+- Session-based admin authentication via IndieLogin.com
+- CSRF protection (state tokens)
+- Session management
+- Admin route protection
+
+**Must Be Implemented** (for Micropub):
+- Token verification endpoint (query user's token endpoint)
+- Bearer token extraction from Authorization header
+- Scope verification (check token has "create" permission)
+- Token storage/caching (optional, for performance)
+
+**Does NOT Implement** (users provide these):
+- Authorization endpoint (users use IndieLogin.com or self-hosted)
+- Token endpoint (users use tokens.indieauth.com or self-hosted)
+- User identity management (users own their domains)
+
+## Implementation Outline
+
+### No Changes Needed for Admin Auth
+The current IndieLogin.com integration (ADR-005) is correct and requires no changes. Each self-hosted StarPunk installation uses its own domain as `client_id` without any registration.
+
+### Required for Micropub Support
+
+#### 1. Token Verification
+```python
+def verify_micropub_token(bearer_token, expected_me):
+    """
+    Verify access token by querying the token endpoint
+
+    Args:
+        bearer_token: Token from Authorization header
+        expected_me: Expected user identity (from StarPunk config)
+
+    Returns:
+        dict: Token info (me, client_id, scope) if valid
+        None: If token is invalid
+    """
+    # Discover token endpoint from expected_me domain
+    token_endpoint = discover_token_endpoint(expected_me)
+
+    # Verify token
+    response = httpx.get(
+        token_endpoint,
+        headers={'Authorization': f'Bearer {bearer_token}'},
+        params={'token': bearer_token}
+    )
+
+    if response.status_code != 200:
+        return None
+
+    data = response.json()
+
+    # Verify token is for expected user
+    if data.get('me') != expected_me:
+        return None
+
+    # Verify token has required scope
+    scope = data.get('scope', '')
+    if 'create' not in scope:
+        return None
+
+    return data
+```
+
+#### 2. Endpoint Discovery
+```python
+def discover_token_endpoint(me_url):
+    """
+    Discover token endpoint from user's profile URL
+
+    Checks for:
+    1. indieauth-metadata endpoint
+    2. Fallback to direct token_endpoint link
+    """
+    response = httpx.get(me_url)
+
+    # Check HTTP Link header
+    link_header = response.headers.get('Link', '')
+    # Parse link header for indieauth-metadata
+
+    # Check HTML <link> tags
+    # Parse HTML for <link rel="indieauth-metadata">
+
+    # Fetch metadata endpoint
+    # Return token_endpoint URL
+```
+
+#### 3. Micropub Endpoint Protection
+```python
+@app.route('/api/micropub', methods=['POST'])
+def micropub_endpoint():
+    # Extract bearer token
+    auth_header = request.headers.get('Authorization', '')
+    if not auth_header.startswith('Bearer '):
+        return {'error': 'unauthorized'}, 401
+
+    bearer_token = auth_header[7:]  # Remove "Bearer "
+
+    # Verify token
+    token_info = verify_micropub_token(bearer_token, ADMIN_ME)
+    if not token_info:
+        return {'error': 'forbidden'}, 403
+
+    # Process Micropub request
+    # Create note
+    # Return 201 with Location header
+```
+
+### Documentation Updates
+
+#### For Users (Setup Guide)
+```markdown
+# Setting Up Your IndieWeb Identity
+
+To publish to StarPunk via Micropub clients:
+
+1. **Add Links to Your Website**
+   Add these to your personal website's <head>:
+   ```html
+   <link rel="authorization_endpoint" href="https://indielogin.com/auth">
+   <link rel="token_endpoint" href="https://tokens.indieauth.com/token">
+   <link rel="micropub" href="https://your-starpunk.example.com/api/micropub">
+   ```
+
+2. **Configure StarPunk**
+   Set your website URL in StarPunk configuration:
+   ```
+   ADMIN_ME=https://your-website.com
+   ```
+
+3. **Use a Micropub Client**
+   - Quill: https://quill.p3k.io
+   - Indigenous (mobile app)
+   - Or any Micropub-compatible client
+
+4. **Advanced: Self-Host Authorization**
+   Instead of IndieLogin.com, you can run your own IndieAuth server.
+   See: https://indieweb.org/IndieAuth#Software
+```
+
+#### For Developers (Architecture Docs)
+Update `/home/phil/Projects/starpunk/docs/architecture/overview.md` to clarify the two authentication flows and explain that StarPunk is a Micropub server, not an authorization server.
+
+## Consequences
+
+### Positive
+- **No development needed**: Current architecture is correct
+- **No registration required**: Works for self-hosted installations out of the box
+- **User control**: Users choose their own authorization provider
+- **Standards compliant**: Proper separation of Micropub server and authorization server
+- **Simple**: StarPunk focuses on publishing, not identity management
+- **Flexible**: Users can switch authorization providers without affecting StarPunk
+
+### Negative
+- **User education required**: Must explain that they need to configure their domain
+- **Not standalone**: StarPunk cannot function completely independently (requires external auth)
+- **Dependency**: Relies on external services (mitigated: user chooses service)
+
+### Neutral
+- **Architectural purity**: Follows IndieWeb principle of separation of concerns
+- **Complexity distribution**: Moves authorization complexity to where it belongs (identity provider)
+
+## V2 Considerations
+
+If there is user demand for a more integrated solution, V2 could add:
+
+### Option A: Embedded IndieAuth Server
+**Pros**:
+- StarPunk becomes completely standalone
+- Users can use StarPunk domain as their identity
+- One-step setup for non-technical users
+
+**Cons**:
+- 40-60 hours development effort
+- Ongoing security maintenance
+- Adds complexity to codebase
+- May violate simplicity principle
+
+**Decision**: Only implement if users request it
+
+### Option B: Hybrid Mode
+**Pros**:
+- Advanced users can use external auth (current behavior)
+- Simple users can use built-in auth
+- Best of both worlds
+
+**Cons**:
+- Even more complexity
+- Two codepaths to maintain
+- Configuration complexity
+
+**Decision**: Defer until V2 user feedback
+
+### Option C: StarPunk-Hosted Service
+**Pros**:
+- One StarPunk authorization server for all installations
+- Users register their StarPunk instance once
+- Simple for end users
+
+**Cons**:
+- Centralized service (not indie)
+- Single point of failure
+- Hosting/maintenance burden
+- Violates IndieWeb principles
+
+**Decision**: Rejected - not aligned with IndieWeb values
+
+## Alternatives Considered
+
+### Alternative 1: Self-Host IndieAuth (Taproot/PHP)
+**Evaluation**:
+- Complexity: Would require running PHP alongside Python
+- Deployment: Two separate applications to manage
+- Maintenance: Security updates for both Python and PHP
+- Verdict: **Rejected** - adds unnecessary complexity
+
+### Alternative 2: Port Taproot to Python
+**Evaluation**:
+- Effort: 40-60 hours development
+- Maintenance: Full responsibility for security
+- Value: Solves a non-existent problem (no registration needed)
+- Verdict: **Rejected** - violates simplicity principle
+
+### Alternative 3: Use OAuth2 Service (GitHub, Google)
+**Evaluation**:
+- Simplicity: Very simple to implement
+- IndieWeb Compliance: **FAIL** - not IndieWeb compatible
+- User Ownership: **FAIL** - users don't own their identity
+- Verdict: **Rejected** - violates core requirements
+
+### Alternative 4: Password Authentication
+**Evaluation**:
+- Simplicity: Moderate (password hashing, reset flows)
+- IndieWeb Compliance: **FAIL** - not IndieWeb authentication
+- Security: Must implement password best practices
+- Verdict: **Rejected** - not aligned with IndieWeb principles
+
+### Alternative 5: Use IndieAuth as Library (Client Side)
+**Evaluation**:
+- Would make StarPunk act as IndieAuth client to discover user's auth server
+- Current architecture already does this for Micropub
+- Admin interface uses simpler session-based auth
+- Verdict: **Already implemented** for Micropub flow
+
+## Migration Plan
+
+### From Current Broken Understanding → Correct Understanding
+
+**No Code Changes Required**
+
+1. **Update Documentation**
+   - Clarify that no registration is needed
+   - Explain the two authentication flows

+# ADR-026: IndieAuth Token Exchange Compliance
+
+## Status
+Accepted
+
+## Context
+StarPunk's IndieAuth implementation is failing to authenticate with certain providers (specifically gondulf.thesatelliteoflove.com) during the token exchange phase. The provider is rejecting our token exchange requests with a "missing grant_type" error.
+
+Our current implementation sends:
+- `code`
+- `client_id`
+- `redirect_uri`
+- `code_verifier` (for PKCE)
+
+But does NOT include `grant_type=authorization_code`.
+
+## Decision
+StarPunk MUST include `grant_type=authorization_code` in all token exchange requests to be compliant with both OAuth 2.0 RFC 6749 and IndieAuth specifications.
+
+## Rationale
+
+### OAuth 2.0 RFC 6749 Compliance
+RFC 6749 Section 4.1.3 explicitly states that `grant_type` is a REQUIRED parameter with the value MUST be set to "authorization_code" for the authorization code grant flow.
+
+### IndieAuth Specification
+While the IndieAuth specification (W3C TR) doesn't use explicit RFC 2119 language (MUST/REQUIRED) for the grant_type parameter, it:
+1. Lists `grant_type=authorization_code` as part of the token request parameters in Section 6.3.1
+2. Shows it in all examples (Example 12)
+3. States that IndieAuth "builds upon the OAuth 2.0 [RFC6749] Framework"
+
+Since IndieAuth builds on OAuth 2.0, and OAuth 2.0 requires this parameter, IndieAuth implementations should include it.
+
+### Provider Compliance
+The provider (gondulf.thesatelliteoflove.com) is **correctly following the specifications** by requiring the `grant_type` parameter.
+
+## Consequences
+
+### Positive
+- Full compliance with OAuth 2.0 RFC 6749
+- Compatibility with all spec-compliant IndieAuth providers
+- Clear, standard-compliant token exchange requests
+
+### Negative
+- Requires immediate code change to add the missing parameter
+- May reveal other non-compliant providers that don't check for this parameter
+
+## Implementation Requirements
+
+The token exchange request MUST include these parameters:
+```
+grant_type=authorization_code  # REQUIRED by OAuth 2.0
+code={authorization_code}      # REQUIRED
+client_id={client_url}         # REQUIRED
+redirect_uri={redirect_url}    # REQUIRED if used in initial request
+me={user_profile_url}          # REQUIRED by IndieAuth (extension to OAuth)
+```
+
+### Note on PKCE
+The `code_verifier` parameter currently being sent is NOT part of the IndieAuth specification. IndieAuth does not mention PKCE (RFC 7636) support. However:
+- Including it shouldn't break compliant providers (they should ignore unknown parameters)
+- It provides additional security for public clients
+- Consider making PKCE optional or detecting provider support
+
+## Alternatives Considered
+
+### Alternative 1: Argue for Optional grant_type
+**Rejected**: While IndieAuth could theoretically make grant_type optional since there's only one grant type, this would break compatibility with OAuth 2.0 compliant libraries and providers.
+
+### Alternative 2: Provider-specific workarounds
+**Rejected**: Creating provider-specific code paths would violate the principle of standards compliance and create maintenance burden.
+
+## Recommendation
+
+**Immediate Action Required**:
+1. Add `grant_type=authorization_code` to all token exchange requests
+2. Maintain the existing parameters
+3. Consider making PKCE optional or auto-detecting provider support
+
+**StarPunk is at fault** - the implementation is missing a required OAuth 2.0 parameter that IndieAuth inherits.

+# ADR-027: IndieAuth Authentication Endpoint Correction
+
+## Status
+Accepted
+
+## Context
+
+StarPunk is encountering authentication failures with certain IndieAuth providers (specifically gondulf.thesatelliteoflove.com). After investigation, we discovered that StarPunk is incorrectly using the **token endpoint** for authentication-only flows, when it should be using the **authorization endpoint**.
+
+### The Problem
+
+When attempting to authenticate with gondulf.thesatelliteoflove.com, the provider returns:
+```json
+{
+  "error": "invalid_grant",
+  "error_description": "Authorization code must be redeemed at the authorization endpoint"
+}
+```
+
+StarPunk is currently sending authentication code redemption requests to `/token` when it should be sending them to the authorization endpoint for authentication-only flows.
+
+### IndieAuth Specification Analysis
+
+According to the W3C IndieAuth specification (https://www.w3.org/TR/indieauth/):
+
+1. **Authentication-only flows** (Section 5.4):
+   - Used when the client only needs to verify user identity
+   - Code redemption happens at the **authorization endpoint**
+   - No `grant_type` parameter is used
+   - Response contains only `{"me": "user-url"}`
+
+2. **Authorization flows** (Section 6.3):
+   - Used when the client needs an access token for API access
+   - Code redemption happens at the **token endpoint**
+   - Requires `grant_type=authorization_code` parameter
+   - Response contains access token and user identity
+
+### Current StarPunk Implementation
+
+StarPunk's current code in `/home/phil/Projects/starpunk/starpunk/auth.py` (lines 410-419):
+
+```python
+token_exchange_data = {
+    "grant_type": "authorization_code",  # WRONG for authentication-only
+    "code": code,
+    "client_id": current_app.config["SITE_URL"],
+    "redirect_uri": f"{current_app.config['SITE_URL']}auth/callback",
+    "code_verifier": code_verifier,  # PKCE verification
+}
+
+token_url = f"{current_app.config['INDIELOGIN_URL']}/token"  # WRONG endpoint
+```
+
+This implementation has two errors:
+1. Uses `/token` endpoint instead of authorization endpoint
+2. Includes `grant_type` parameter which should not be present for authentication-only flows
+
+## Decision
+
+StarPunk must correct its IndieAuth authentication implementation to comply with the specification:
+
+1. **Use the authorization endpoint** for code redemption in authentication-only flows
+2. **Remove the `grant_type` parameter** from authentication requests
+3. **Keep PKCE parameters** (`code_verifier`) as they are still required
+
+## Rationale
+
+### Why This Matters
+
+1. **Standards Compliance**: The IndieAuth specification clearly distinguishes between authentication and authorization flows
+2. **Provider Compatibility**: Some providers (like gondulf) strictly enforce the specification
+3. **Correct Semantics**: StarPunk only needs to verify admin identity, not obtain an access token
+
+### Authentication vs Authorization
+
+StarPunk's admin login is an **authentication-only** use case:
+- We only need to verify the admin's identity (`me` URL)
+- We don't need an access token to access external resources
+- We create our own session after successful authentication
+
+This is fundamentally different from Micropub client authorization where:
+- External clients need access tokens
+- Tokens are used to authorize API access
+- The token endpoint is the correct choice
+
+## Implementation
+
+### Required Changes
+
+In `/home/phil/Projects/starpunk/starpunk/auth.py`, the `handle_callback` function must be updated:
+
+```python
+def handle_callback(code: str, state: str, iss: Optional[str] = None) -> Optional[str]:
+    # ... existing state verification code ...
+
+    # Prepare authentication request (NOT token exchange)
+    auth_data = {
+        # NO grant_type parameter for authentication-only flows
+        "code": code,
+        "client_id": current_app.config["SITE_URL"],
+        "redirect_uri": f"{current_app.config['SITE_URL']}auth/callback",
+        "code_verifier": code_verifier,  # PKCE verification still required
+    }
+
+    # Use authorization endpoint (NOT token endpoint)
+    # The same endpoint used for the initial authorization request
+    auth_url = f"{current_app.config['INDIELOGIN_URL']}/auth"  # or /authorize
+
+    # Exchange code for identity (authentication-only)
+    response = httpx.post(
+        auth_url,
+        data=auth_data,
+        timeout=10.0,
+    )
+
+    # Response will be: {"me": "https://user.example.com"}
+    # NOT an access token response
+```
+
+### Endpoint Discovery Consideration
+
+IndieAuth providers may use different paths for their authorization endpoint:
+- IndieLogin.com uses `/auth`
+- Some providers use `/authorize`
+- The gondulf provider appears to use its root domain as the authorization endpoint
+
+The correct approach is to:
+1. Discover the authorization endpoint from the provider's metadata
+2. Use the same endpoint for both authorization initiation and code redemption
+3. Store the discovered endpoint during the initial authorization request
+
+## Consequences
+
+### Positive
+- **Specification Compliance**: Correctly implements IndieAuth authentication flow
+- **Provider Compatibility**: Works with strict IndieAuth implementations
+- **Semantic Correctness**: Uses the right flow for the use case
+
+### Negative
+- **Breaking Change**: May affect compatibility with providers that accept both endpoints
+- **Testing Required**: Need to verify with multiple IndieAuth providers
+
+### Migration Impact
+- Existing sessions remain valid (no database changes)
+- Only affects new login attempts
+- Should be transparent to users
+
+## Testing Strategy
+
+Test with multiple IndieAuth providers:
+1. **IndieLogin.com** - Current provider (should continue working)
+2. **gondulf.thesatelliteoflove.com** - Strict implementation
+3. **tokens.indieauth.com** - Token-only endpoint (should fail for auth)
+4. **Self-hosted implementations** - Various compliance levels
+
+## Alternatives Considered
+
+### Alternative 1: Support Both Endpoints
+Attempt token endpoint first, fall back to authorization endpoint on failure.
+- **Pros**: Maximum compatibility
+- **Cons**: Not specification-compliant, adds complexity
+- **Verdict**: Rejected - violates standards
+
+### Alternative 2: Make Endpoint Configurable
+Allow admin to configure which endpoint to use.
+- **Pros**: Flexible for different providers
+- **Cons**: Confusing for users, not needed if we follow spec
+- **Verdict**: Rejected - specification is clear
+
+### Alternative 3: Always Use Token Endpoint
+Continue current implementation, document incompatibility.
+- **Pros**: No code changes needed
+- **Cons**: Violates specification, limits provider choice
+- **Verdict**: Rejected - incorrect implementation

+# ADR-028: Micropub Implementation Strategy
+
+## Status
+
+Proposed
+
+## Context
+
+StarPunk needs a Micropub endpoint to achieve V1 release. Micropub is a W3C standard that allows external clients to create, update, and delete posts on a website. This is a critical IndieWeb building block that enables users to post from various apps and services.
+
+### Current State
+- StarPunk has working IndieAuth authentication (authorization endpoint with PKCE)
+- Note CRUD operations exist in `starpunk/notes.py`
+- File-based storage with SQLite metadata is implemented
+- **Missing**: Micropub endpoint for external posting
+- **Missing**: Token endpoint for API authentication
+
+### Requirements Analysis
+
+Based on the W3C Micropub specification review, we identified:
+
+**Minimum Required Features:**
+- Bearer token authentication (header or form parameter)
+- Create posts via form-encoded requests
+- HTTP 201 Created response with Location header
+- Proper error responses with JSON error bodies
+
+**Recommended Features:**
+- JSON request support for complex operations
+- Update and delete operations
+- Query endpoints (config, source, syndicate-to)
+
+**Optional Features (Not for V1):**
+- Media endpoint for file uploads
+- Syndication targets
+- Complex post types beyond notes
+
+## Decision
+
+We will implement a **minimal but complete Micropub server** for V1, focusing on core functionality that enables real-world usage while deferring advanced features.
+
+### Implementation Approach
+
+1. **Token Management System**
+   - New token endpoint (`/auth/token`) for IndieAuth code exchange
+   - Secure token storage using SHA256 hashing
+   - 90-day token expiry with scope validation
+   - Database schema updates for token management
+
+2. **Micropub Endpoint Architecture**
+   - Single endpoint (`/micropub`) handling all operations
+   - Support both form-encoded and JSON content types
+   - Delegate to existing `notes.py` CRUD functions
+   - Proper error handling and status codes
+
+3. **V1 Feature Scope** (Simplified per user decision)
+   - ✅ Create posts (form-encoded and JSON)
+   - ✅ Query endpoints (config, source)
+   - ✅ Bearer token authentication
+   - ✅ Scope-based authorization (create only)
+   - ❌ Media endpoint (post-V1)
+   - ❌ Update operations (post-V1)
+   - ❌ Delete operations (post-V1)
+   - ❌ Syndication (post-V1)
+
+### Technology Choices
+
+| Component | Technology | Rationale |
+|-----------|------------|-----------|
+| Token Storage | SQLite with SHA256 hashing | Secure, consistent with existing database |
+| Token Format | Random URL-safe strings | Simple, secure, no JWT complexity |
+| Request Parsing | Flask built-in + custom normalization | Handles both form and JSON naturally |
+| Response Format | JSON for errors, headers for success | Follows Micropub spec exactly |
+
+## Rationale
+
+### Why Minimal V1 Scope?
+
+1. **Get to V1 Faster**: Core create functionality enables 90% of use cases
+2. **Real Usage Feedback**: Deploy and learn from actual usage patterns
+3. **Reduced Complexity**: Fewer edge cases and error conditions
+4. **Clear Foundation**: Establish patterns before adding complexity
+
+### Why Not JWT Tokens?
+
+1. **Unnecessary Complexity**: JWT adds libraries and complexity
+2. **No Distributed Validation**: Single-server system doesn't need it
+3. **Simpler Revocation**: Database tokens are easily revoked
+4. **Consistent with IndieAuth**: Random tokens match the pattern
+
+### Why Reuse Existing CRUD?
+
+1. **Proven Code**: `notes.py` already handles file/database sync
+2. **Consistency**: Same validation and error handling
+3. **Maintainability**: Single source of truth for note operations
+4. **Atomic Operations**: Existing transaction handling
+
+### Security Considerations
+
+1. **Token Hashing**: Never store plaintext tokens
+2. **Scope Enforcement**: Each operation checks required scopes
+3. **HTTPS Required**: Enforce in production configuration
+4. **Token Expiry**: 90-day lifetime limits exposure
+5. **Single-Use Auth Codes**: Prevent replay attacks
+
+## Consequences
+
+### Positive
+
+✅ **Enables V1 Release**: Removes the last blocker for V1
+✅ **Real IndieWeb Participation**: Can post from standard clients
+✅ **Clean Architecture**: Clear separation of concerns
+✅ **Extensible Design**: Easy to add features later
+✅ **Security First**: Proper token handling from day one
+
+### Negative
+
+⚠️ **Limited Initial Features**: No media uploads in V1
+⚠️ **Database Migration Required**: Token schema changes needed
+⚠️ **Client Testing Needed**: Must verify with real Micropub clients
+⚠️ **Additional Complexity**: New endpoints and token management
+
+### Neutral
+
+- **8-10 Day Implementation**: Reasonable timeline for critical feature
+- **New Dependencies**: None required (using existing libraries)
+- **Documentation Burden**: Must document API for users
+
+## Implementation Plan
+
+### Phase 1: Token Infrastructure (Days 1-3)
+- Token database schema and migration
+- Token generation and storage functions
+- Token endpoint for code exchange
+- Scope validation helpers
+
+### Phase 2: Micropub Core (Days 4-7)
+- Main endpoint handler
+- Property normalization for form/JSON
+- Create post functionality
+- Error response formatting
+
+### Phase 3: Queries & Polish (Days 6-8)
+- Config and source query endpoints
+- Authorization endpoint with admin session check
+- Discovery headers and links
+- Client testing and documentation
+
+**Note**: Timeline reduced from 8-10 days to 6-8 days due to V1 scope simplification (no update/delete)
+
+## Alternatives Considered
+
+### Alternative 1: Full Micropub Implementation
+**Rejected**: Too complex for V1, would delay release by weeks
+
+### Alternative 2: Custom API Instead of Micropub
+**Rejected**: Breaks IndieWeb compatibility, requires custom clients
+
+### Alternative 3: JWT-Based Tokens
+**Rejected**: Unnecessary complexity for single-server system
+
+### Alternative 4: Separate Media Endpoint First
+**Rejected**: Not required for text posts, can add later
+
+## Compliance
+
+### Standards Compliance
+- ✅ W3C Micropub specification
+- ✅ IndieAuth specification for tokens
+- ✅ OAuth 2.0 Bearer Token usage
+
+### Project Principles
+- ✅ Minimal code (reuses existing CRUD)
+- ✅ Standards-first (follows W3C spec)
+- ✅ No lock-in (standard protocols)
+- ✅ Progressive enhancement (can add features)
+
+## Risks and Mitigations
+
+| Risk | Impact | Probability | Mitigation |
+|------|--------|-------------|------------|
+| Token security breach | High | Low | SHA256 hashing, HTTPS required |
+| Client incompatibility | Medium | Medium | Test with 3+ clients before release |
+| Scope creep | Medium | High | Strict V1 feature list |
+| Performance issues | Low | Low | Simple operations, indexed database |
+
+## Success Metrics
+
+1. **Functional Success**
+   - Posts can be created from Indigenous app
+   - Posts can be created from Quill
+   - Token endpoint works with IndieAuth flow
+
+2. **Performance Targets**
+   - Post creation < 500ms
+   - Token validation < 50ms
+   - Query responses < 200ms
+
+3. **Security Requirements**
+   - All tokens hashed in database
+   - Expired tokens rejected
+   - Invalid scopes return 403

+# ADR-029: Micropub IndieAuth Integration Strategy
+
+## Status
+Accepted
+
+## Context
+
+The developer review of our Micropub design (ADR-028) revealed critical issues and questions about how IndieAuth and Micropub integrate. This ADR addresses all architectural decisions needed to proceed with implementation.
+
+### Critical Issues Identified
+
+1. **Token endpoint missing required `me` parameter** in the IndieAuth spec
+2. **PKCE confusion** - it's not part of IndieAuth spec, but StarPunk uses it with IndieLogin.com
+3. **Database security issue** - tokens stored in plain text
+4. **Missing `authorization_codes` table** for token exchange
+5. **Property mapping rules** undefined for Micropub to StarPunk conversion
+6. **Authorization endpoint location** unclear
+7. **Two authentication flows** need clarification
+
+### V1 Scope Decision
+
+The user has agreed to **simplify V1** by:
+- ✅ Omitting update operations from V1
+- ✅ Omitting delete operations from V1
+- ✅ Focusing on create-only for V1 release
+- Post-V1 features will be tracked separately
+
+## Decision
+
+We will implement a **hybrid IndieAuth architecture** that clearly separates admin authentication from Micropub authorization.
+
+### Architectural Decisions
+
+#### 1. Token Endpoint `me` Parameter (RESOLVED)
+
+**Issue**: IndieAuth spec requires `me` parameter in token exchange, but our design missed it.
+
+**Decision**: Add `me` parameter validation to token endpoint.
+
+**Implementation**:
+```python
+# Token exchange request MUST include:
+POST /auth/token
+grant_type=authorization_code
+code={code}
+client_id={client_url}
+redirect_uri={redirect_url}
+me={user_profile_url}  # REQUIRED by IndieAuth spec
+```
+
+**Validation**:
+- Verify `me` matches the value stored with the authorization code
+- Return error if mismatch (prevents code hijacking)
+
+#### 2. PKCE Strategy (RESOLVED)
+
+**Issue**: PKCE is not part of IndieAuth spec, but StarPunk uses it with IndieLogin.com.
+
+**Decision**: Make PKCE **optional but recommended**.
+
+**Implementation**:
+- Check for `code_challenge` in authorization request
+- If present, require `code_verifier` in token exchange
+- If absent, proceed without PKCE (spec-compliant)
+- Document as security enhancement beyond spec
+
+**Rationale**:
+- IndieLogin.com supports PKCE as an extension
+- Other IndieAuth providers may not support it
+- Making it optional ensures broader compatibility
+
+#### 3. Token Storage Security (RESOLVED)
+
+**Issue**: Current `tokens` table stores tokens in plain text (major security vulnerability).
+
+**Decision**: Implement **immediate migration** to hashed token storage.
+
+**Migration Strategy**:
+```sql
+-- Step 1: Create new secure tokens table
+CREATE TABLE tokens_secure (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    token_hash TEXT UNIQUE NOT NULL,  -- SHA256 hash
+    me TEXT NOT NULL,
+    client_id TEXT,
+    scope TEXT DEFAULT 'create',
+    created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    expires_at TIMESTAMP NOT NULL,
+    last_used_at TIMESTAMP,
+    revoked_at TIMESTAMP
+);
+
+-- Step 2: Invalidate all existing tokens (security breach recovery)
+-- Since we can't hash plain text tokens retroactively, all must be revoked
+DROP TABLE IF EXISTS tokens;
+
+-- Step 3: Rename secure table
+ALTER TABLE tokens_secure RENAME TO tokens;
+
+-- Step 4: Create indexes
+CREATE INDEX idx_tokens_hash ON tokens(token_hash);
+CREATE INDEX idx_tokens_me ON tokens(me);
+CREATE INDEX idx_tokens_expires ON tokens(expires_at);
+```
+
+**Security Notice**: All existing tokens will be invalidated. Users must re-authenticate.
+
+#### 4. Authorization Codes Table (RESOLVED)
+
+**Issue**: Design references `authorization_codes` table that doesn't exist.
+
+**Decision**: Create the table as part of Micropub implementation.
+
+**Schema**:
+```sql
+CREATE TABLE authorization_codes (
+    code TEXT PRIMARY KEY,
+    code_hash TEXT UNIQUE NOT NULL,  -- SHA256 hash for security
+    me TEXT NOT NULL,
+    client_id TEXT NOT NULL,
+    redirect_uri TEXT NOT NULL,
+    scope TEXT DEFAULT 'create',
+    code_challenge TEXT,  -- Optional PKCE
+    code_challenge_method TEXT,  -- S256 if PKCE used
+    created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    expires_at TIMESTAMP NOT NULL,
+    used_at TIMESTAMP  -- Prevent replay attacks
+);
+
+CREATE INDEX idx_auth_codes_hash ON authorization_codes(code_hash);
+CREATE INDEX idx_auth_codes_expires ON authorization_codes(expires_at);
+```
+
+#### 5. Property Mapping Rules (RESOLVED)
+
+**Issue**: Functions like `extract_title()` and `extract_content()` are undefined.
+
+**Decision**: Define explicit mapping rules for V1.
+
+**Micropub → StarPunk Mapping**:
+```python
+# Content mapping (required)
+content = properties.get('content', [''])[0]  # First content value
+if not content:
+    return error_response("invalid_request", "Content is required")
+
+# Title mapping (optional)
+# Option 1: Use 'name' property if provided
+title = properties.get('name', [''])[0]
+# Option 2: If no name, extract from content (first line up to 50 chars)
+if not title and content:
+    first_line = content.split('\n')[0]
+    title = first_line[:50] + ('...' if len(first_line) > 50 else '')
+
+# Tags mapping
+tags = properties.get('category', [])  # All category values become tags
+
+# Published date (respect if provided, otherwise use current time)
+published = properties.get('published', [''])[0]
+if published:
+    # Parse ISO 8601 date
+    created_at = parse_iso8601(published)
+else:
+    created_at = datetime.now()
+
+# Slug generation
+mp_slug = properties.get('mp-slug', [''])[0]
+if mp_slug:
+    slug = slugify(mp_slug)
+else:
+    slug = generate_slug(title or content[:30])
+```
+
+### Q1: Authorization Endpoint Location (RESOLVED)
+
+**Issue**: Design mentions `/auth/authorization` but it doesn't exist.
+
+**Decision**: Create **NEW** `/auth/authorization` endpoint for Micropub clients.
+
+**Rationale**:
+- Keep admin login (`/auth/login`) separate from Micropub authorization
+- Clear separation of concerns
+- Follows IndieAuth spec naming conventions
+
+**Implementation**:
+```python
+@bp.route("/auth/authorization", methods=["GET", "POST"])
+def authorization_endpoint():
+    """
+    IndieAuth authorization endpoint for Micropub clients
+
+    GET: Display authorization form
+    POST: Process authorization and redirect with code
+    """
+    if request.method == "GET":
+        # Parse IndieAuth parameters
+        response_type = request.args.get('response_type')
+        client_id = request.args.get('client_id')
+        redirect_uri = request.args.get('redirect_uri')
+        state = request.args.get('state')
+        scope = request.args.get('scope', 'create')
+        me = request.args.get('me')
+        code_challenge = request.args.get('code_challenge')
+
+        # Validate parameters
+        if response_type != 'code':
+            return error_response("unsupported_response_type")
+
+        # Check if user is logged in (via admin session)
+        if not verify_admin_session():
+            # Redirect to login, then back here
+            session['pending_auth'] = request.url
+            return redirect(url_for('auth.login_form'))
+
+        # Display authorization form
+        return render_template('auth/authorize.html',
+            client_id=client_id,
+            scope=scope,
+            redirect_uri=redirect_uri)
+
+    else:  # POST
+        # User approved/denied authorization
+        # Generate authorization code
+        # Store in authorization_codes table
+        # Redirect to client with code
+```
+
+### Q2: Two Authentication Flows Integration (RESOLVED)
+
+**Decision**: Maintain **two separate flows** with clear boundaries.
+
+**Flow 1: Admin Login** (Existing)
+- Purpose: Admin access to StarPunk interface
+- Path: `/auth/login` → IndieLogin.com → `/auth/callback`
+- Result: Session cookie for admin panel
+- No changes needed
+
+**Flow 2: Micropub Authorization** (New)
+- Purpose: Micropub client authorization
+- Path: `/auth/authorization` → `/auth/token`
+- Result: Bearer token for API access
+
+**Integration Point**: The authorization endpoint checks for admin session:
+```python
+def authorization_endpoint():
+    # Check if admin is logged in
+    if not has_admin_session():
+        # Store authorization request
+        # Redirect to admin login
+        # After login, return to authorization
+        return redirect_to_login_with_return()
+
+    # Admin is logged in, show authorization form
+    return show_authorization_form()
+```
+
+**Key Design Choice**: We act as our **own authorization server** for Micropub, not delegating to IndieLogin.com for this flow. This is because:
+1. IndieLogin.com doesn't issue access tokens
+2. We need to control scopes and token lifetime
+3. We already have admin authentication to verify the user
+
+### Q3: Scope Validation Rules (RESOLVED)
+
+**Issue**: What happens when client requests no scopes?
+
+**Decision**: Implement **Option C** - Allow empty scope during authorization, reject at token endpoint.
+
+**Rationale**: This matches the IndieAuth spec requirement exactly.
+
+**Implementation**:
+```python
+def handle_authorization():
+    scope = request.args.get('scope', '')
+
+    # Store whatever scope was requested (even empty)
+    authorization_code = create_authorization_code(
+        scope=scope,  # Can be empty string
+        # ... other parameters
+    )
+
+def handle_token_exchange():
+    auth_code = get_authorization_code(code)
+
+    # IndieAuth spec: MUST NOT issue token if no scope
+    if not auth_code.scope:
+        return error_response("invalid_scope",
+            "Authorization code was issued without scope")
+
+    # Issue token with the authorized scope
+    token = create_access_token(scope=auth_code.scope)
+```
+
+### Q4: V1 Scope - Update/Delete Operations (RESOLVED)
+
+**Decision**: Remove update/delete from V1 completely.
+
+**Changes Required**:
+1. Remove `handle_update()` and `handle_delete()` from design doc
+2. Remove update/delete from supported scopes in V1
+3. Return "invalid_request" if action=update or action=delete
+4. Document in project plan for post-V1
+
+**V1 Supported Actions**:
+- ✅ action=create (or no action - default)
+- ❌ action=update → error response
+- ❌ action=delete → error response
+
+### Q5: Token Storage Security Fix (RESOLVED)
+
+**Decision**: Fix the security issue as part of Micropub implementation.
+
+**Implementation Plan**:
+1. Create migration to new secure schema
+2. Hash all new tokens before storage
+3. Document that existing tokens will be invalidated
+4. Add security notice to changelog

+
+## Consequences
+
+### Positive
+- ✅ All spec compliance issues resolved
+- ✅ Clear separation between admin auth and Micropub auth
+- ✅ Security vulnerability in token storage fixed
+- ✅ Simplified V1 scope (create-only)
+- ✅ PKCE optional for compatibility
+- ✅ Clear property mapping rules
+
+### Negative
+- ⚠️ Existing tokens will be invalidated (security fix)
+- ⚠️ More complex than initially designed
+- ⚠️ Two authorization flows to maintain
+
+### Neutral
+- We become our own authorization server (for Micropub only)
+- Admin must be logged in to authorize Micropub clients

+# Token Security Migration Strategy
+
+## Overview
+
+This document outlines the migration strategy for fixing the critical security issue where access tokens are stored in plain text in the database. This migration will invalidate all existing tokens as a necessary security measure.
+
+## Security Issue
+
+**Current State**: The `tokens` table stores tokens in plain text, which is a major security vulnerability. If the database is compromised, all tokens are immediately usable by an attacker.
+
+**Target State**: Store only SHA256 hashes of tokens, making stolen database contents useless without the original tokens.
+
+## Migration Plan
+
+### Phase 1: Database Schema Migration
+
+#### Migration Script (`migrations/005_token_security.sql`)
+
+```sql
+-- Migration: Fix token security and add Micropub support
+-- Version: 0.10.0
+-- Breaking Change: This will invalidate all existing tokens
+
+-- Step 1: Create new secure tokens table
+CREATE TABLE tokens_secure (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    token_hash TEXT UNIQUE NOT NULL,      -- SHA256 hash of token
+    me TEXT NOT NULL,                     -- User identity URL
+    client_id TEXT,                        -- Client application URL
+    scope TEXT DEFAULT 'create',          -- Granted scopes
+    created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    expires_at TIMESTAMP NOT NULL,         -- Token expiration
+    last_used_at TIMESTAMP,                -- Track usage
+    revoked_at TIMESTAMP                   -- Soft revocation
+);
+
+-- Step 2: Create indexes for performance
+CREATE INDEX idx_tokens_secure_hash ON tokens_secure(token_hash);
+CREATE INDEX idx_tokens_secure_me ON tokens_secure(me);
+CREATE INDEX idx_tokens_secure_expires ON tokens_secure(expires_at);
+
+-- Step 3: Create authorization_codes table for Micropub
+CREATE TABLE authorization_codes (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,

+
+### Phase 2: Code Implementation
+
+#### Token Generation and Storage
+
+```python
+# starpunk/tokens.py
+import hashlib
+import secrets
+from datetime import datetime, timedelta
+
+def generate_token() -> str:
+    """Generate cryptographically secure random token"""
+    return secrets.token_urlsafe(32)
+
+def hash_token(token: str) -> str:
+    """Create SHA256 hash of token"""
+    return hashlib.sha256(token.encode()).hexdigest()
+
+def create_access_token(me: str, client_id: str, scope: str, db) -> str:
+    """
+    Create new access token and store hash in database
+
+    Returns:
+        Plain text token (only returned once, never stored)
+    """
+    token = generate_token()
+    token_hash = hash_token(token)
+
+    expires_at = datetime.now() + timedelta(days=90)
+
+    db.execute("""
+        INSERT INTO tokens (token_hash, me, client_id, scope, expires_at)
+        VALUES (?, ?, ?, ?, ?)
+    """, (token_hash, me, client_id, scope, expires_at))
+    db.commit()
+
+    return token  # Return plain text to user ONCE
+
+def verify_token(token: str, db) -> dict:
+    """
+    Verify token by comparing hash
+
+    Returns:
+        Token info if valid, None if invalid/expired

+        db.commit()
+
+        return dict(row)
+
+    return None
+```
+
+### Phase 3: Migration Execution
+
+#### Step-by-Step Process
+
+1. **Backup Database**
+   ```bash
+   cp data/starpunk.db data/starpunk.db.backup-$(date +%Y%m%d)
+   ```
+
+2. **Notify Users** (if applicable)
+   - Email or announcement about token invalidation
+   - Explain security improvement
+   - Provide re-authentication instructions
+
+3. **Apply Migration**
+   ```python
+   # In starpunk/migrations.py
+   def run_migration_005(conn):
+       """Apply token security migration"""
+       with open('migrations/005_token_security.sql', 'r') as f:
+           conn.executescript(f.read())
+       conn.commit()
+   ```
+
+4. **Update Code**
+   - Deploy new token handling code
+   - Update all token verification points
+   - Add proper error messages
+
+5. **Test Migration**
+   ```python
+   # Verify new schema
+   cursor = conn.execute("PRAGMA table_info(tokens)")
+   columns = {col[1] for col in cursor.fetchall()}
+   assert 'token_hash' in columns
+   assert 'token' not in columns  # Old column gone
+
+   # Test token operations
+   token = create_access_token("https://user.example", "app", "create", conn)
+   assert verify_token(token, conn) is not None
+   assert verify_token("invalid", conn) is None
+   ```
+
+### Phase 4: Post-Migration Validation
+
+#### Security Checklist
+
+- [ ] Verify no plain text tokens in database
+- [ ] Confirm all tokens are hashed with SHA256
+- [ ] Test token creation returns plain text once
+- [ ] Test token verification works with hash
+- [ ] Verify expired tokens are rejected
+- [ ] Check revoked tokens are rejected
+- [ ] Audit logs show migration completed
+
+#### Functional Testing
+
+- [ ] Micropub client can obtain new token
+- [ ] New tokens work for API requests
+- [ ] Invalid tokens return 401 Unauthorized
+- [ ] Token expiry is enforced
+- [ ] Last used timestamp updates
+
+## Rollback Plan
+
+If critical issues arise:
+
+1. **Restore Database**
+   ```bash
+   cp data/starpunk.db.backup-YYYYMMDD data/starpunk.db
+   ```
+
+2. **Revert Code**
+   ```bash
+   git revert <migration-commit>
+   ```
+
+3. **Investigate Issues**
+   - Review migration logs
+   - Test in development environment
+   - Fix issues before retry
+
+## User Communication
+
+### Pre-Migration Notice
+
+```
+Subject: Important Security Update - Token Re-authentication Required
+
+Dear StarPunk User,
+
+We're implementing an important security update that will require you to
+re-authenticate any Micropub clients you use with StarPunk.
+
+What's Changing:
+- Enhanced token security (SHA256 hashing)
+- All existing access tokens will be invalidated
+- You'll need to re-authorize Micropub clients
+
+When:
+- [Date and time of migration]
+
+What You Need to Do:
+1. After the update, go to your Micropub client
+2. Remove and re-add your StarPunk site
+3. Complete the authorization flow again
+
+This change significantly improves the security of your StarPunk installation.
+
+Thank you for your understanding.
+```
+
+### Post-Migration Notice
+
+```
+Subject: Security Update Complete - Please Re-authenticate
+
+The security update has been completed successfully. All previous access
+tokens have been invalidated for security reasons.
+
+To continue using Micropub clients:
+1. Open your Micropub client (Quill, Indigenous, etc.)
+2. Remove your StarPunk site if listed
+3. Add it again and complete authorization
+4. You're ready to post!
+
+If you experience any issues, please contact support.
+```
+
+## Timeline
+
+| Phase | Duration | Description |
+|-------|----------|-------------|
+| Preparation | 1 day | Create migration scripts, test in dev |
+| Communication | 1 day | Notify users of upcoming change |
+| Migration | 2 hours | Apply migration, deploy code |
+| Validation | 2 hours | Test and verify success |
+| Support | 1 week | Help users re-authenticate |
+
+## Risk Assessment
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| Data loss | High | Full backup before migration |
+| User disruption | Medium | Clear communication, documentation |
+| Migration failure | Low | Test in dev, have rollback plan |
+| Performance impact | Low | Indexes on hash columns |
+
+## Long-term Benefits
+
+1. **Security**: Compromised database doesn't expose usable tokens
+2. **Compliance**: Follows security best practices
+3. **Auditability**: Can track token usage via last_used_at
+4. **Revocability**: Can revoke tokens without deletion
+5. **Foundation**: Proper structure for OAuth/IndieAuth
+
+## Conclusion
+
+While this migration will cause temporary disruption by invalidating existing tokens, it's a necessary security improvement that brings StarPunk in line with security best practices. The migration is straightforward, well-tested, and includes comprehensive rollback procedures if needed.

+# IndieAuth Authentication Endpoint Correction
+
+**Date**: 2025-11-22
+**Version**: 0.9.4
+**Type**: Bug Fix
+
+## Summary
+
+Corrected the IndieAuth code redemption endpoint from `/token` to `/authorize` for authentication-only flows, and removed the unnecessary `grant_type` parameter.
+
+## Problem
+
+StarPunk was using the wrong endpoint for IndieAuth authentication. Per the IndieAuth specification:
+
+- **Authentication-only flows** (identity verification): Use the **authorization endpoint** (`/authorize`)
+- **Authorization flows** (getting access tokens): Use the **token endpoint** (`/token`)
+
+StarPunk only needs identity verification (to check if the user is the admin), so it should POST to the authorization endpoint, not the token endpoint.
+
+Additionally, the `grant_type` parameter is only required for token endpoint requests (OAuth 2.0 access token requests), not for authentication-only code redemption at the authorization endpoint.
+
+### IndieAuth Spec Reference
+
+From the IndieAuth specification:
+> If the client only needs to know the user who logged in, the client will exchange the authorization code at the authorization endpoint. If the client needs an access token, the client will exchange the authorization code at the token endpoint.
+
+## Solution
+
+1. Changed the endpoint from `/token` to `/authorize`
+2. Removed the `grant_type` parameter (not needed for authentication-only)
+3. Updated debug logging to reflect "code verification" instead of "token exchange"
+
+### Before
+
+```python
+token_exchange_data = {
+    "grant_type": "authorization_code",  # Not needed for authentication-only
+    "code": code,
+    "client_id": current_app.config["SITE_URL"],
+    "redirect_uri": f"{current_app.config['SITE_URL']}auth/callback",
+    "code_verifier": code_verifier,
+}
+
+token_url = f"{current_app.config['INDIELOGIN_URL']}/token"  # Wrong endpoint
+```
+
+### After
+
+```python
+token_exchange_data = {
+    "code": code,
+    "client_id": current_app.config["SITE_URL"],
+    "redirect_uri": f"{current_app.config['SITE_URL']}auth/callback",
+    "code_verifier": code_verifier,
+}
+
+# Use authorization endpoint for authentication-only flow (identity verification)
+token_url = f"{current_app.config['INDIELOGIN_URL']}/authorize"
+```
+
+## Files Modified
+
+1. **`starpunk/auth.py`**
+   - Line 410-423: Removed `grant_type`, changed endpoint to `/authorize`, added explanatory comments
+   - Line 434: Updated log message from "token exchange request" to "code verification request to authorization endpoint"
+   - Line 445: Updated comment to clarify authentication-only flow
+   - Line 455: Updated log message from "token exchange response" to "code verification response"
+
+2. **`starpunk/__init__.py`**
+   - Version bumped from 0.9.3 to 0.9.4
+
+3. **`CHANGELOG.md`**
+   - Added 0.9.4 release notes
+
+## Testing
+
+- All tests pass at the same rate as before (no new failures introduced)
+- 28 pre-existing test failures remain (related to OAuth metadata and h-app tests for removed functionality from v0.8.0)
+- 486 tests pass
+
+## Technical Context
+
+The v0.9.3 fix that added `grant_type` was based on an incorrect assumption that IndieLogin.com uses the token endpoint for all code redemption. However:
+
+1. IndieLogin.com follows the IndieAuth spec which distinguishes between authentication and authorization
+2. For authentication-only (which is all StarPunk needs), the authorization endpoint is correct
+3. The token endpoint is only for obtaining access tokens (which StarPunk doesn't need)

+# IndieAuth Token Exchange grant_type Fix
+
+**Date**: 2025-11-22
+**Version**: 0.9.3
+**Type**: Bug Fix
+
+## Summary
+
+Added the required `grant_type=authorization_code` parameter to the IndieAuth token exchange request.
+
+## Problem
+
+The token exchange request in `starpunk/auth.py` was missing the `grant_type` parameter. Per OAuth 2.0 spec (RFC 6749 Section 4.1.3), the token exchange request MUST include:
+
+```
+grant_type=authorization_code
+```
+
+Some IndieAuth providers that strictly validate OAuth 2.0 compliance would reject the token exchange request without this parameter.
+
+## Solution
+
+Added `"grant_type": "authorization_code"` to the `token_exchange_data` dictionary in the `handle_callback` function.
+
+### Before
+
+```python
+token_exchange_data = {
+    "code": code,
+    "client_id": current_app.config["SITE_URL"],
+    "redirect_uri": f"{current_app.config['SITE_URL']}auth/callback",
+    "code_verifier": code_verifier,
+}
+```
+
+### After
+
+```python
+token_exchange_data = {
+    "grant_type": "authorization_code",
+    "code": code,
+    "client_id": current_app.config["SITE_URL"],
+    "redirect_uri": f"{current_app.config['SITE_URL']}auth/callback",
+    "code_verifier": code_verifier,
+}
+```
+
+## Files Modified
+
+1. **`starpunk/auth.py`** (line 412)
+   - Added `"grant_type": "authorization_code"` to token_exchange_data
+
+2. **`starpunk/__init__.py`** (line 156)
+   - Version bumped from 0.9.2 to 0.9.3
+
+3. **`CHANGELOG.md`**
+   - Added 0.9.3 release notes
+
+## Testing
+
+- Module imports successfully
+- Pre-existing test failures are unrelated (OAuth metadata and h-app tests for removed functionality)
+- No new test failures introduced
+
+## References
+

+
+## Changes Made
+
+### URL Replacements
+- **Old URL**: `https://indieauth.spec.indieweb.org/`
+- **New URL**: `https://www.w3.org/TR/indieauth/`
+- **Total Replacements**: 42 references updated
+
+### Why This Matters
+
+1. **Authority**: The W3C version is the official, authoritative specification
+2. **Maintenance**: W3C specifications receive regular updates and errata
+3. **Permanence**: W3C URLs are guaranteed to be permanent and stable
+4. **Standards Compliance**: Referencing W3C directly shows commitment to web standards
+
+## Verification
+
+### Pre-Update Status
+- Found 42 references to the old IndieAuth spec URL (`indieauth.spec.indieweb.org`)
+- No references to the W3C version
+
+### Post-Update Status
+- 0 references to the old spec URL
+- 42 references to the W3C version (`www.w3.org/TR/indieauth`)
+- All documentation now consistently references the W3C specification
+
+### Validation Command
+```bash
+# Check for any remaining old references
+grep -r "indieauth\.spec\.indieweb\.org" /home/phil/Projects/starpunk --include="*.md" --include="*.py"
+# Result: No matches found
+
+# Count W3C references
+grep -r "w3\.org/TR/indieauth" /home/phil/Projects/starpunk --include="*.md" --include="*.py" | wc -l
+# Result: 42 references
+```
+
+## Impact Assessment
+
+### Positive Impacts
+1. **Documentation Consistency**: All documentation now points to the same authoritative source
+2. **Future-Proofing**: W3C URLs are permanent and will not change
+3. **Professional Standards**: Demonstrates commitment to official web standards
+4. **Improved Credibility**: References to W3C specifications carry more weight
+
+### No Negative Impacts
+- No functional changes to code
+- No breaking changes to existing functionality
+- URLs redirect properly, so existing bookmarks still work
+- All section references remain valid
+
+## Recommendations
+
+1. **Documentation Standards**: Add a documentation standard requiring all specification references to use official W3C URLs where available
+2. **CI/CD Check**: Consider adding a check to prevent introduction of old spec URLs
+3. **Regular Review**: Periodically review external references to ensure they remain current
+
+## Conclusion
+
+Successfully completed standardization of all IndieAuth specification references across the StarPunk documentation. All 42 references have been updated from the old IndieWeb.org URL to the official W3C specification URL. This ensures the project documentation remains consistent, professional, and aligned with web standards best practices.
+

+
+**Note**: This report documents an architectural documentation update. No code changes were required as Python source files did not contain direct specification URLs in comments.

+- Replay attack protection
+- Parameter validation (client_id, redirect_uri, me mismatch)
+- PKCE validation (S256 method)
+- Scope validation
+- Empty scope authorization (per IndieAuth spec)
+
+### Technical Issues Resolved
+
+#### Issue 1: Database Schema Detection
+
+**Problem**: Migration system incorrectly detected fresh databases as "legacy" or "current"
+
+**Solution**: Updated `is_schema_current()` in `migrations.py` to check for:
+- `authorization_codes` table existence
+- `token_hash` column in tokens table
+
+This ensures fresh databases skip migrations but legacy databases apply them.
+
+#### Issue 2: Datetime Timezone Mismatch
+
+**Problem**: Python's `datetime.now()` returns local time, but SQLite's `datetime('now')` returns UTC
+
+**Solution**: Use `datetime.utcnow()` consistently for all expiry calculations
+
+**Impact**: Authorization codes and tokens now properly expire based on UTC time
+
+## What's Next
+
+### Phase 2: Authorization & Token Endpoints (In Progress)
+
+**Remaining Tasks**:
+
+1. **Token Endpoint** (`/auth/token`) - REQUIRED FOR V1
+   - Exchange authorization code for access token
+   - Validate all parameters (code, client_id, redirect_uri, me)
+   - Optional PKCE verification
+   - Return token response per IndieAuth spec
+
+2. **Authorization Endpoint** (`/auth/authorization`) - REQUIRED FOR V1
+   - Display authorization form
+   - Require admin session
+   - Generate authorization code
+   - Redirect with code
+
+3. **Micropub Endpoint** (`/micropub`) - REQUIRED FOR V1
+   - Bearer token authentication
+   - Handle create action only (V1 scope)
+   - Parse form-encoded and JSON requests
+   - Create notes via existing `notes.py` CRUD
+   - Return 201 with Location header
+   - Query endpoints (config, source, syndicate-to)
+
+4. **Integration Testing**
+   - Test complete flow: authorization → token exchange → post creation
+   - Test with real Micropub clients (Indigenous, Quill)
+
+5. **Documentation Updates**
+   - Update CHANGELOG.md (breaking change)
+   - Increment version to 0.10.0
+   - API documentation
+
+## Architecture Decisions Made
+
+No new architectural decisions were required. Implementation follows ADR-029 exactly.
+
+## Questions for Architect
+
+None at this time. Phase 1 implementation matches the design specifications.

+-- Migration: Secure token storage and add authorization codes
+-- Date: 2025-11-24
+-- Version: 0.10.0 (BREAKING CHANGE)
+-- ADR: ADR-029 Micropub IndieAuth Integration Strategy
+--
+-- SECURITY FIX: Migrate tokens table to use SHA256 hashed storage
+-- BREAKING CHANGE: All existing tokens will be invalidated
+--
+-- This migration:
+-- 1. Creates new secure tokens table with token_hash column
+-- 2. Drops old insecure tokens table (invalidates all existing tokens)
+-- 3. Creates authorization_codes table for IndieAuth token exchange
+-- 4. Adds appropriate indexes for performance
