Run the instance in private mode when instance_url is not configured: the API rejects anonymous requests except the auth-bootstrap set (sign-in, token refresh, instance profile/settings, SSO providers, share-link access) plus first-run user creation, and the web UI redirects anonymous visitors to /auth instead of /explore. Setting instance_url keeps the current public behavior. Access tokens and personal access tokens are never gated.
Enforcement lives in a shared Authorizer used by both the Connect interceptor and the gRPC-gateway middleware; the file server applies the same rule to public-memo attachments and avatars. Also merges the duplicated Authenticate/AuthenticateToUser token dispatch behind resolveBearer, dedups the AuthContext unauthenticated state, extracts the redirect decision into a pure shouldGatePrivateInstance helper, and prints the access mode at startup.
Add ApplyToContext and AuthenticateToUser helpers to the auth package,
then remove the duplicated auth code spread across the MCP middleware,
file server, Connect interceptor, and gRPC-Gateway middleware.
- auth.ApplyToContext: single place to set claims/user into context after Authenticate()
- auth.AuthenticateToUser: resolves any credential (bearer token or refresh cookie) to a *store.User
- MCP middleware: replaced manual PAT DB lookup + expiry check with Authenticator.AuthenticateByPAT
- File server: replaced authenticateByBearerToken/authenticateByRefreshToken with AuthenticateToUser
- Connect interceptor + Gateway middleware: replaced duplicated context-setting block with ApplyToContext
- MCPService now accepts secret to construct its own Authenticator
- Add serveMediaStream() to stream video/audio without loading into memory
- Use http.ServeFile for local files (zero-copy, handles range requests)
- Redirect to S3 presigned URLs for S3-stored media files
- Refactor for better maintainability:
- Extract constants and pre-compile lookup maps
- Consolidate duplicated S3 client creation logic
- Split authentication into focused helper methods
- Group code by responsibility with section comments
- Add setSecurityHeaders() and setMediaHeaders() helpers
- Remove SessionCookieName and SessionSlidingDuration constants
- Remove ExtractSessionCookieFromHeader() function
- Remove SessionIDContextKey and GetSessionID() function
- Remove sessionID parameter from SetUserInContext()
- Remove SessionID field from AuthResult struct
- Remove session cookie extraction from middleware
- Update documentation to reflect JWT + PAT only auth
Session cookies were never being set since migration to refresh token
authentication. This change removes ~50 lines of dead code and clarifies
that the system uses JWT access tokens, refresh tokens, and PATs only.
- Fix cookie expiration timezone to use GMT (RFC 6265 compliance)
- Use Connect RPC client for token refresh instead of fetch
- Fix error code checking (numeric Code.Unauthenticated instead of string)
- Prevent infinite redirect loop when already on /auth page
- Fix protobuf Timestamp conversion using timestampDate helper
- Store access token in sessionStorage to avoid unnecessary refreshes on page reload
- Add refresh token cookie fallback for attachment authentication
- Improve error handling with proper type checking

Migrates attachment and avatar binary serving from gRPC endpoints to a new dedicated HTTP fileserver package, fixing Safari video playback issues and improving architectural separation.
Key changes:
- Created server/router/fileserver package for all binary file serving
- Removed GetAttachmentBinary and GetUserAvatar gRPC endpoints from proto
- Implemented native HTTP handlers with full range request support
- Added authentication support (session cookies + JWT) to fileserver
- New avatar endpoint supports lookup by user ID or username
- Eliminated duplicate auth constants (imports from api/v1)
HTTP endpoints:
- Attachments: /file/attachments/:uid/:filename (unchanged URL)
- Avatars: /file/users/:identifier/avatar (new URL format)
This fixes Safari video/audio playback by using http.ServeContent() which properly handles HTTP 206 Partial Content responses and range request headers.
