Aquilia Auth Session Builder

Purpose

Configure and implement Aquilia auth/session flows using the actual auth and session subsystems.

Trigger Conditions

Use for login/session identity, JWT/token config, password hashing, RBAC/ABAC, clearance decorators, route guards, OAuth2/PKCE, MFA, session stores/transports, or auth middleware behavior.

Inputs

Auth settings: secret key, algorithm, issuer, audience, token TTLs, password policy.
Session policies: TTL, idle timeout, persistence, cookie/header transport, store.
Controller protection requirements: roles, scopes, permissions, clearance conditions.

Execution Flow

Enable sessions with Workspace.sessions(...); auth forces sessions on in server middleware setup.
Configure auth through Integration.auth(...), AuthConfig, or workspace security settings as appropriate.
Use decorators/guards from aquilia.auth.decorators, aquilia.auth.guards, and clearance helpers for controller protection.
Use AuthManager, TokenManager, PasswordHasher, stores, and session bridge through DI where possible.
Test protected routes with aquilia.testing.TestClient bearer token or session cookie helpers.

Constraints

Do not use insecure default secrets; AuthConfig.secret_key must be set explicitly for real auth.
Cookie security settings depend on environment; do not turn off httponly casually.
Clearance and auth decorators should return structured auth faults or challenge responses, not raw exceptions.

Implementation Anchors

aquilia/auth/*.py, aquilia/auth/integration/*.py, aquilia/sessions/*.py, aquilia/middleware_ext/session_middleware.py, tests/test_auth_system.py, tests/test_sessions_system.py, examples/auth_app/.

Examples

Protect a route with @authenticated or @requires(AdminGuard()).
Add DEFAULT_USER_POLICY to workspace sessions.
Implement a clearance rule with @grant(level=AccessLevel.WRITE, conditions=[is_owner_or_admin]).

Failure Handling

If auth is enabled but sessions fail, inspect session engine creation first. Token errors should map to auth faults. Password validation failures come from PasswordPolicy; return user-safe messages only.
