Eliminates scope escalation security vulnerability by removing Hybrid Flow and making Progressive Consent the only OAuth mode. Changes: - Delete oauth_callback() and oauth_token() (Hybrid Flow only, ~314 lines) - Fix scope flows: Flow 1 requests resource scopes, Flow 2 requests identity+offline - Remove ENABLE_PROGRESSIVE_CONSENT flag (always enabled in OAuth mode) - Update documentation to reflect Progressive Consent as default - Delete test_adr004_hybrid_flow.py test file - Remove unused variables (ruff lint fixes) Security improvements: - No scope escalation: client gets exactly what it requests - Clear separation: MCP session tokens vs Nextcloud offline tokens - OAuth2 compliant: follows best practices for scope handling 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# ===== AUTHENTICATION MODE =====
|
|
# Choose ONE of the following:
|
|
|
|
# Option 1: OAuth2/OIDC (RECOMMENDED - More Secure)
|
|
# - Requires Nextcloud OIDC app installed and configured
|
|
# - Admin must enable "Dynamic Client Registration" in OIDC app settings
|
|
# - Leave NEXTCLOUD_USERNAME and NEXTCLOUD_PASSWORD empty to use OAuth mode
|
|
# - OAuth client credentials are stored encrypted in SQLite (TOKEN_STORAGE_DB)
|
|
# - Optional: Pre-register client and provide credentials (otherwise auto-registers)
