If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/tencentmusic/supersonic shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

SuperSonic is an AI+BI platform that merges Chat BI (LLM-powered natural language querying via Text2SQL) with Headless BI (semantic layer governance). It provides a unified Chat BI web interface where business users query data in natural language, while exposing curated semantic models (metrics, dimensions, tags) through a governed API layer. The key innovation is reducing LLM hallucination by injecting semantic context into prompts and offloading SQL complexity (joins, formulas) to the semantic layer rather than the LLM. Modular monorepo: auth/ (authentication & authorization layer), semantic/ (semantic models and Text2SQL engine), chat/ (Chat BI UI and orchestration), common/ (shared utilities), assembly/ (packaging/deployment scripts). Java backend uses Spring Boot; TypeScript frontend likely in a separate webapp module. Assembly scripts (supersonic-build.sh, supersonic-docker-compose.sh) indicate multi-environment deployments (bare metal, Docker, Kubernetes).

Data engineers and BI architects building governed semantic layers (building the auth/ auth layer, semantic/ semantic models, and chat/ NL interface); business analysts and end users querying via the Chat BI web interface; and companies needing both traditional BI dashboards and LLM-driven conversational analytics without reimplementing data governance.

Actively developed and production-ready. Multi-platform CI/CD in place (ubuntu-ci.yml, centos-ci.yml, mac-ci.yml, windows-ci.yml, docker-publish.yml), with a comprehensive CHANGELOG.md and docsite (https://supersonicbi.github.io/). The codebase is substantial (3M+ LOC Java, 1.4M TypeScript), indicating real-world use. Owned by Tencent Music, so backed by enterprise infrastructure.

Risk factors: monolithic Java+TypeScript codebase (200+ build artifacts likely) means steep onboarding and slow iteration; no visible GitHub issues/PRs in the file list to assess community velocity; Java 21 requirement (maven.compiler.target=21) narrows runtime environments. Authentication module (auth/) is critical path—any bug here breaks entire platform. Dependency count not visible, but large Spring Boot + LLM stack typical of this space suggests supply-chain risk.

No specific recent commit data visible in the file list, but the presence of multi-platform CI workflows (windows-ci.yml, mac-ci.yml) and Docker publishing suggest active DevOps investment. The CHANGELOG.md and feature templates (.github/ISSUE_TEMPLATE/) indicate ongoing feature development and community contributions.

Clone the repo: git clone https://github.com/tencentmusic/supersonic.git && cd supersonic. Build with Maven (Java 21+ required): mvn clean install -DskipTests. Start via Docker: bash assembly/bin/supersonic-docker-run.sh or native: bash assembly/bin/supersonic-daemon.sh start. (Exact startup command not visible—check CLAUDE.md or assembly/bin/*.sh for details.)

Daily commands: Dev backend: mvn spring-boot:run -pl [module] (specific module TBD). Dev frontend: likely npm run dev in a webapp/ or frontend/ folder (not visible in file list). Full Docker Compose: bash assembly/bin/supersonic-docker-compose.sh. For exact commands, check assembly/build/build.xml and CLAUDE.md.

• auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/service/UserService.java — Core authentication service interface defining user lifecycle operations; all auth implementations must conform to this contract.
• auth/api/src/main/java/com/tencent/supersonic/auth/api/authorization/service/AuthService.java — Primary authorization service interface managing resource access control and permission evaluation; foundational for security model.
• auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/interceptor/AuthenticationInterceptor.java — Request interception layer for enforcing authentication; determines flow for all incoming requests requiring auth validation.
• auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/persistence/repository/UserRepository.java — User data access abstraction; critical boundary between service logic and persistent storage for user credentials and tokens.
• auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/pojo/UserToken.java — Token data model representing authenticated user sessions; used throughout the platform for identity propagation.
• auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/strategy/UserStrategyFactory.java — Factory for pluggable user authentication strategies (fake, HTTP header, database); enables extensible auth backends.
• auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/utils/UserHolder.java — ThreadLocal context holder for current authenticated user; enables request-scoped user identity access throughout the application.

Add a new user authentication strategy (e.g., LDAP, OAuth)

1. Implement the UserStrategy interface with your auth logic (token validation, user resolution) (auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/service/UserStrategy.java)
2. Register your strategy in the factory to be conditionally instantiated (auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/strategy/UserStrategyFactory.java)
3. Add configuration property to enable/configure your strategy (auth.strategy=your-strategy) (auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/config/AuthenticationConfig.java)

Add a new user data source (e.g., custom LDAP/SAML backend)

1. Implement UserAdaptor interface to map external user attributes to UserToken (auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/adaptor/UserAdaptor.java)
2. Wire your adaptor in the default implementation or create a new strategy (auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/adaptor/DefaultUserAdaptor.java)
3. Register adaptor in ComponentFactory or AuthenticationConfig (auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/utils/ComponentFactory.java)

Extend authorization with custom permission rules

1. Define new AuthRule or DimensionFilter objects in authorization POJOs (auth/api/src/main/java/com/tencent/supersonic/auth/api/authorization/pojo/AuthRule.java)
2. Implement authorization logic in a new service or extend existing AuthService (auth/api/src/main/java/com/tencent/supersonic/auth/api/authorization/service/AuthService.java)
3. Add REST endpoint in authorization controller to manage rules (auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/rest/UserController.java)

Add a new user management REST endpoint

1. Define a new request DTO if needed in authentication/request package (auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/request/UserReq.java)
2. Add a @PostMapping/@GetMapping/@PutMapping method in the controller (auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/rest/UserController.java)
3. Call UserServiceImpl to execute business logic (persisted via UserRepository) (auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/service/UserServiceImpl.java)

Java 21 requirement: pom.xml enforces maven.compiler.target=21; older JDKs will fail silently at runtime. Missing module visibility in file list: semantic/, chat/, common/ directories are referenced in dependencies but not fully listed—build will fail without understanding the full monorepo structure. No visible application.properties/application.yml: Spring Boot config location unknown; likely requires environment variables or externalized config (check assembly/bin/supersonic-env.sh). Auth layer is mandatory: UserAdaptor must be implemented or configured even for dev—missing adaptor causes authentication to silently fail. Docker or shell scripts required: No bare JAR execution documented; relying on assembly/ scripts means misconfigured paths in those scripts break all deployments.

• Text2SQL / NL2SQL — Core problem SuperSonic solves—converting natural language to SQL reliably is the foundation of Chat BI, and SuperSonic's innovation is reducing hallucination by pairing LLM with semantic layer.
• Semantic Layer / Headless BI — SuperSonic's second pillar—a governed, unified semantic model (metrics, dimensions, relationships) that both Chat BI and traditional BI query against, ensuring consistency.
• Prompt Engineering with Domain Context — SuperSonic injects business semantics (column definitions, sample values, relationships) into LLM prompts to reduce hallucination—core insight differentiating it from naive Text2SQL.
• SPI (Service Provider Interface) — SuperSonic explicitly uses Java SPI for extensibility (mentioned in README)—custom auth adaptors, datasource connectors, and LLM providers are plugged in via SPI, not hard-coded.
• SQL AST Manipulation — SuperSonic's semantic layer offloads join generation, formula computation, and aggregation logic from LLM to deterministic SQL builders—requires understanding SQL Abstract Syntax Trees.
• Chat BI vs. Traditional BI — SuperSonic bridges two paradigms—conversational analytics (Chat BI) for exploratory queries and governed dashboards (Headless BI) for reporting; understanding when each is appropriate is crucial.
• Token-based Authentication & Authorization — SuperSonic's auth/ module implements OAuth2-like token validation (UserToken.java) with role-based access control—critical for securing semantic model access in multi-tenant scenarios.

• apache/superset — Headless BI alternative offering semantic layer + visualization; SuperSonic differentiates by adding LLM-driven Chat BI on top.
• google/python-bigquery — BigQuery semantic API that SuperSonic could use as a backend datasource—relevant for teams already on GCP.
• meltanolabs/tap-postgres — Data extraction tool; SuperSonic requires semantic models built from normalized datasources, often ingested via Meltano-like EL tools.
• langchain-ai/langchain — Core LLM orchestration framework—SuperSonic's Text2SQL engine likely builds on or wraps LangChain's SQL agent patterns.
• dbt-labs/dbt-core — Semantic layer and data transformation—many SuperSonic users define metrics/dimensions via dbt models before exposing them in SuperSonic.

Add comprehensive unit tests for auth/api authentication and authorization modules

The auth/api module contains critical authentication (UserService, UserStrategy, UserAdaptor) and authorization (AuthGroup, AuthRule, DimensionFilter) logic, but no visible test directory exists in the file structure. This is high-risk for a security-sensitive component. New contributors can add JUnit 5 tests covering UserService implementations, AuthenticationConfig initialization, and AuthorizedResourceResp filtering logic.

• [ ] Create auth/api/src/test/java directory structure mirroring auth/api/src/main/java
• [ ] Add unit tests for auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/service/UserService.java implementations
• [ ] Add unit tests for auth/api/src/main/java/com/tencent/supersonic/auth/api/authorization/pojo validators (AuthRule, DimensionFilter validation logic)
• [ ] Add integration test for UserAdaptor.java to verify custom user adaptation workflows
• [ ] Update auth/api/pom.xml to include spring-boot-starter-test and mockito dependencies
• [ ] Reference the test patterns used in other modules (common, etc.) for consistency

Create GitHub Actions workflow for auth module security scanning and dependency audit

While ubuntu-ci.yml, mac-ci.yml, windows-ci.yml, and centos-ci.yml exist in .github/workflows, there is no dedicated security scanning workflow. Given that auth/api handles authentication, tokens (UserToken.java), and authorization rules, a dedicated workflow for OWASP dependency checks and secret scanning would significantly improve security posture before merging.

• [ ] Create .github/workflows/auth-security-audit.yml with separate jobs for dependency-check, secret scanning, and SAST
• [ ] Add dependency-check step targeting auth/api/pom.xml to scan for known CVEs in dependencies (spring-boot-starter-web, jakarta.validation-api, etc.)
• [ ] Add GitGuardian or similar secret scanning to prevent accidental token/credential commits in auth modules
• [ ] Configure workflow to fail the build if vulnerabilities above a certain severity threshold are found
• [ ] Document findings and remediation steps in auth/api/SECURITY.md (new file)

Add integration documentation and examples for auth/api custom UserAdaptor implementations

The UserAdaptor.java interface exists in auth/api but there is no README or examples showing how external systems (LDAP, OAuth, SAML) should implement custom authentication adapters. This is a critical integration point for enterprise deployments. New contributors can create detailed documentation with concrete examples.

• [ ] Create auth/api/AUTHENTICATION_ADAPTOR_GUIDE.md explaining the UserAdaptor interface contract and lifecycle
• [ ] Add code example implementations for common scenarios: LDAP adapter (extends UserAdaptor), OAuth2 adapter, and SAML adapter
• [ ] Document how custom UserAdaptor beans are discovered and registered via AuthenticationConfig.java
• [ ] Add example configuration in auth/api/src/main/resources/application-example.yml showing how to enable different adapters
• [ ] Link this guide from the main README.md and CLAUDE.md under an 'Authentication Integration' section
• [ ] Include troubleshooting section for common UserAdaptor implementation mistakes (null checks, exception handling, etc.)

• Add unit tests for auth/api/src/main/java/com/tencent/supersonic/auth/api/authentication/pojo/ POJOs (UserToken.java, Organization.java, UserWithPassword.java)—currently no test files visible, and these are critical for validation logic.
• Document the UserAdaptor interface with JavaDoc and a concrete example implementation (LDAP vs. local DB)—the authenticat ion adaptor pattern is complex but lacks usage examples in the visible files.
• Create a troubleshooting guide for assembly/bin/supersonic-daemon.sh startup failures (JVM args, port conflicts, missing config files)—these shell scripts are opaque and no debug guide exists.

• High · Java 21 Compiler Target - Potential Compatibility and Security Risks — auth/api/pom.xml, maven.compiler.source/target properties. The project is configured to use Java 21 as both source and target (maven.compiler.source/target=21). Java 21 is a recent version with potential compatibility issues, and security patches may lag behind LTS versions. This can introduce risks in production environments, especially for enterprise deployments. Fix: Consider using a Long-Term Support (LTS) version of Java such as Java 17 or Java 11. If Java 21 is necessary, ensure all dependencies are tested and compatible, and establish a regular patching schedule.
• High · Missing Input Validation Dependencies — auth/api/pom.xml, dependencies section. While jakarta.validation-api is included, there is no explicit dependency on a validation implementation (e.g., hibernate-validator). This may lead to validation annotations not being enforced at runtime, allowing invalid or malicious data to pass through to business logic and potentially cause injection vulnerabilities. Fix: Add an explicit dependency on a validation implementation such as org.hibernate.validator:hibernate-validator or ensure it's provided transitively by spring-boot-starter-web. Verify that @Valid and @Validated annotations are properly enforced on all API endpoints.
• High · Potential SQL Injection in Semantic Layer / Text2SQL Implementation — Semantic layer components, Text2SQL query builders. The project implements Text2SQL functionality (Chat BI feature that converts natural language to SQL queries). The file structure indicates presence of semantic layer and query processing components. Without explicit evidence of parameterized queries, ORM usage, or query sanitization in the codebase structure, there is significant risk of SQL injection attacks when converting user input to SQL. Fix: Enforce use of parameterized queries/prepared statements. Use ORM frameworks (e.g., JPA/Hibernate) exclusively. Implement strict input validation and whitelist allowed table/column names. Add SQL query logging and monitoring. Conduct security testing specifically targeting Text2SQL injection vectors.
• High · Insufficient Authentication/Authorization Implementation — auth/authentication/src/main/java/com/tencent/supersonic/auth/authentication/interceptor/AuthenticationInterceptor.java, @AuthenticationIgnore annotation. The auth module contains authentication and authorization components (AuthenticationInterceptor, AuthService, UserStrategy). However, the presence of @AuthenticationIgnore annotation suggests some endpoints can bypass authentication. Without proper enforcement across all endpoints, sensitive operations (data access, configuration changes) may be accessible without authentication. Fix: Implement a secure-by-default authentication policy where authentication is required unless explicitly and carefully exempted. Create a whitelist of endpoints that should be unauthenticated. Audit all uses of @AuthenticationIgnore. Ensure sensitive operations (data queries, admin functions) require both authentication and authorization checks.
• Medium · Missing Security Headers Configuration — Spring Boot application configuration (not visible in provided structure). No visible security headers configuration (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Strict-Transport-Security, etc.) in the Spring Boot configuration. This exposes the application to common web vulnerabilities like clickjacking, MIME-sniffing, and man-in-the-middle attacks. Fix: Configure security headers in Spring Security or via a filter. Add WebSecurityConfigurerAdapter configuration or SecurityFilterChain bean to set: Content-Security-Policy, X-Frame-Options: DENY, X-Content-Type-Options: nosniff, Strict-Transport-Security, X-XSS-Protection.
• Medium · Potential Cross-Site Scripting (XSS) Risk in Chat BI Interface — Chat BI visualization components, frontend rendering logic. The project provides a Chat BI interface for users to query data and visualize results. Without explicit evidence of output encoding and sanitization in the visualization layer, user-controlled data rendered in charts or tables could lead to stored or reflected XSS attacks. Fix: Implement strict output encoding for all user-controlled data rendered in the UI. Use framework-provided templating with auto-escaping (e.g., Thymeleaf, FreeMarker). For client-side rendering, use libraries that auto-escape by default. Validate and sanitize all data returned from API endpoints before rendering.
• Medium · Missing CORS Configuration Security — undefined. No explicit CORS configuration is Fix: undefined
