- Add AuthState, TokenPartialUser, decode_access_token_claims to public API
- Add sync_authenticate_request and async_authenticate_request exports
- Existing exports unchanged
- TokenPartialUser frozen dataclass for unverified JWT payload extraction
- AuthState frozen dataclass for authentication results
- decode_access_token_claims extracts user info without signature verification
- _extract_token_from_headers handles Authorization and x-stack-auth headers
- sync_authenticate_request and async_authenticate_request compose with JWKS verifier
- PaginatedResult[T] generic wrapping nested {items, pagination: {next_cursor}} shape
- Convenience properties .next_cursor and .has_next_page
- Package __init__.py exports all models, errors, and PaginatedResult
- SyncAPIClient/AsyncAPIClient intentionally excluded from public API
- Tests verify pagination with ServerUser and Team types
- BaseAPIClient generic base with header construction, URL building,
response parsing via x-stack-actual-status and x-stack-known-error
- SyncAPIClient wrapping httpx.Client with context manager support
- AsyncAPIClient wrapping httpx.AsyncClient with async context manager
- Exponential backoff retry for idempotent methods (GET/PUT/DELETE)
- 429 rate limit handling with Retry-After header support
- POST/PUT/PATCH with no body sends {} as JSON
- All 26 tests passing
- BaseUser and ServerUser with camelCase aliases and millis-to-datetime properties
- Team, ServerTeam, TeamMemberProfile, TeamInvitation with timestamp conversions
- ActiveSession with GeoInfo nested model
- ContactChannel and TeamPermission/ProjectPermission
- Tests for user and team model parsing, inheritance, and field conversion
- StackAuthError base with code/message/details and from_response() factory
- 13 category subclasses: Authentication, NotFound, Validation, PermissionDenied,
Conflict, OAuth, Passkey, ApiKey, Payment, Email, RateLimit, Cli, Analytics
- Complete _ERROR_CODE_MAP with 143 error codes from known-errors.tsx
- StackAuthModel base class with Pydantic v2 ConfigDict and millis conversion
- Package exports via __init__.py with __all__
- Test StackAuthError base class storage and string representation
- Test all 13 category subclasses inherit from StackAuthError
- Test from_response() dispatch for known and unknown error codes
- Test StackAuthModel config and millis conversion
- Package skeleton with pyproject.toml (stubs only, tests expected to fail)
