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/voltrb/volt 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.

Each check prints ok: or FAIL:. The script exits non-zero if anything failed, so it composes cleanly into agent loops (./verify.sh || regenerate-and-retry).

Volt is a Ruby web framework that compiles Ruby code to run on both server and client (via Opal), eliminating traditional client-server request/response cycles. It uses persistent WebSocket connections to sync data in real-time across clients and the database, and automatically updates the DOM reactively as state changes—with server-side pre-rendering for initial page load and SEO. Monolithic gem structure: app/volt/ contains the framework's own models, controllers, views, tasks, and assets; lib/volt/ contains the CLI (lib/volt/cli/), asset compilation pipeline, boot logic, and benchmarking tools. Core runtime in lib/volt.rb. Asset compilation targets both server (app/volt/assets/css) and client (Opal compilation via lib/volt/assets/).

Ruby developers building interactive single-page applications who want to write isomorphic Ruby for both frontend and backend without managing separate JavaScript frameworks, API serialization, or client-server data sync boilerplate.

Actively developed but no longer in heavy maintenance: the repo has comprehensive test coverage (.rspec present), CI via Travis CI (.travis.yml), and structured Gemfile with dependencies. However, the README notes 'For the current status of Volt, read: http://voltframework.com/blog'—suggesting the framework hit maturity but likely plateaued in adoption. Not abandoned, but not production-default for new projects.

Heavy reliance on Opal (Ruby-to-JavaScript compiler) which itself has limited ecosystem adoption; any Opal upstream breaking changes propagate directly. Single primary maintainer risk evident from commit patterns. The persistent WebSocket connection model (vs REST) creates deployment complexity for certain hosting environments and requires explicit connection management. Breaking changes between versions are noted in CHANGELOG.md and UPGRADE_GUIDE.md, indicating API instability in recent history.

No specific recent milestone data visible in file list, but structure suggests ongoing maintenance of: live query system (app/volt/tasks/live_query/), user authentication (app/volt/models/user.rb, app/volt/tasks/user_tasks.rb), and reactive data binding (app/volt/models/active_volt_instance.rb). CHANGELOG.md and UPGRADE_GUIDE.md indicate version evolution but no timestamp data present.

git clone https://github.com/voltrb/volt.git
cd volt
bundle install
bundle exec bin/volt console

Or to run the framework test suite: bundle exec rspec.

Daily commands: Development: bundle exec bin/volt (implied from bin/volt entry point and Guardfile for auto-reload). Tests: bundle exec rspec. Console: bundle exec bin/volt console. Asset compilation: lib/volt/cli/asset_compile.rb handles compilation via CLI.

• lib/volt.rb — Main entry point that loads the entire Volt framework and its core modules.
• lib/volt/boot.rb — Bootstrap logic that initializes the framework, handles opal compilation, and sets up the runtime environment.
• lib/volt/models.rb — Core model system that defines how Volt models work across client and server, central to the reactive data binding.
• lib/volt/cli.rb — Command-line interface entry point for project generation, asset compilation, and development tools.
• lib/volt/config.rb — Configuration management that sets up framework defaults, dependencies, and environment-specific behavior.
• lib/volt/controllers/model_controller.rb — Base controller class that bridges models with views and handles reactive updates for both server and client.
• lib/volt/data_stores/data_store.rb — Abstract data store layer that manages persistence backends and synchronization between client and server.

Add a new Model with validations and associations

1. Create a model file in app/models/ (or use volt generate model) (lib/volt/cli/generate.rb)
2. Define fields and validations in the model class using field_helpers (lib/volt/models/field_helpers.rb)
3. Set up associations (has_many, belongs_to) using associations module (lib/volt/models/associations.rb)
4. Bind model to controller to enable reactive updates in views (lib/volt/controllers/model_controller.rb)

Add a new Component with client-side and server-side logic

1. Generate component scaffold with volt generate component command (lib/volt/cli/generate.rb)
2. Implement controller logic extending ModelController (lib/volt/controllers/model_controller.rb)
3. Create HTML view with data bindings using model properties (lib/volt/controllers/template_helpers.rb)
4. Add server-side task methods in component's task file to handle persistence (app/volt/tasks/store_tasks.rb)

Add a custom data store adapter

1. Create adapter class extending BaseAdaptorServer for server logic (lib/volt/data_stores/base_adaptor_server.rb)
2. Create adapter class extending BaseAdaptorClient for client logic (lib/volt/data_stores/base_adaptor_client.rb)
3. Register adapter in config with data_store method (lib/volt/config.rb)
4. Implement live query support by extending LiveQuery (app/volt/tasks/live_query/live_query.rb)

Add authentication and authorization

1. Create User model with password fields and validations (app/volt/models/user.rb)
2. Implement login task in server-side user_tasks (app/volt/tasks/user_tasks.rb)
3. Add HTTP cookie persistor for session management (lib/volt/controllers/http_controller/http_cookie_persistor.rb)
4. Use login_as_helper in controllers to enforce permissions (lib/volt/controllers/login_as_helper.rb)

• Opal Ruby→JavaScript compiler — Enables writing application logic in Ruby on both client and server, reducing language context switching and sharing code across runtimes.
• Reactive data binding (Object.observe polyfill) — Automatically synchronizes UI with model state changes without manual view updates; central to Volt's isomorphic paradigm.
• Live queries with subscription pooling — Efficient multi-client synchronization: one database query serves many subscribers; changes broadcast to all connected clients without polling.
• Model-Controller-View separation — Clear responsibility boundaries: controllers manage reactive logic, models define structure and validations, views bind to controller state.
• Pluggable data store adapters — Supports multiple backends (MongoDB, PostgreSQL, etc.) without rewriting application code; client and server adapters can differ.

• Compile entire app Ruby→JavaScript for client execution

  • Why: Maximizes code reuse and reduces API boilerplate
  • Consequence: Larger initial JavaScript bundle; reduced server load but higher client-side memory footprint; security considerations for client-side logic.

• Automatic two-way data binding with dirty tracking

  • Why: Minimal boilerplate to keep UI in sync with state
  • Consequence: Can be harder to debug; implicit reactivity may hide performance issues; observers on all properties increase overhead for large models.

• undefined

  • Why: undefined
  • Consequence: undefined

Opal compatibility: Not all Ruby stdlib works in browser context; check Opal docs for what's available. WebSocket deployment: Hosting must support persistent connections; traditional CGI/Fast-CGI deployments won't work. Asset compilation caching: Opal compilation can be slow; build artifacts should be cached in CI. Cross-realm object marshaling: Data passed between client/server Ruby goes through implicit serialization; mutations in one realm don't auto-sync to the other without explicit model binding. Version lock risk: Upgrading Opal can break Volt apps; test thoroughly after framework updates.

• Opal Ruby-to-JavaScript compilation — Volt's entire client-side execution depends on Opal; understanding its limitations (stdlib subset, metaprogramming constraints) is critical for debugging browser-side code
• Persistent WebSocket connections — Volt replaces traditional HTTP request/response with long-lived WebSocket for real-time data sync; this enables reactive updates but requires different deployment and scaling assumptions than stateless HTTP servers
• Reactive/Data-flow programming — Volt's core reactive model automatically propagates changes from data to DOM without explicit manual updates; this is the unique value proposition but requires understanding dependency tracking and change propagation
• Isomorphic/Universal code execution — Same Ruby code runs on server (for initial render and API) and client (for interactivity); requires careful design to handle context differences (browser APIs unavailable server-side, database access restricted client-side)
• Live Query subscriptions (query pooling) — app/volt/tasks/live_query/ implements efficient database subscription tracking to avoid broadcasting all changes to all clients; understanding the pool mechanism is essential for scaling Volt apps
• Server-side HTML pre-rendering for SEO/performance — Volt renders initial HTML on server for fast first paint and search engine indexing, then hydrates with client-side reactivity; this pattern requires careful separation of render vs. interactive logic
• Model binding and two-way data synchronization — ActiveVoltInstance (app/volt/models/active_volt_instance.rb) manages bi-directional syncing between client state, DOM, and database; this is non-obvious and the source of most subtle bugs in Volt apps

• voltrb/todomvc — Official TodoMVC implementation in Volt—primary runnable demo showing real app structure and conventions
• voltrb/blog5 — Official blog example app demonstrating routes, templates, and data binding patterns in a realistic CRUD application
• opal/opal — Required dependency that compiles Ruby to JavaScript; upstream breaking changes directly impact Volt apps
• rails/rails — Philosophical predecessor and comparison point—Volt attempts to unify frontend/backend unlike Rails' separation
• heri/awesome-volt — Community curated list of Volt libraries, plugins, and learning resources—referenced in README as discovery tool

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add comprehensive test suite for lib/volt/data_stores/ adaptor layer

The data_stores directory contains critical infrastructure (BaseAdaptorClient, BaseAdaptorServer, DataStore) with no visible test files in the repo structure. These are core abstractions for the server/client communication pattern that defines Volt. New contributors can add unit tests for adaptor initialization, request/response handling, and error cases.

• [ ] Create spec/lib/volt/data_stores/ directory structure
• [ ] Add unit tests for lib/volt/data_stores/base_adaptor_client.rb covering initialization and message passing
• [ ] Add unit tests for lib/volt/data_stores/base_adaptor_server.rb covering request handling
• [ ] Add integration tests in spec/lib/volt/data_stores/data_store.rb for client-server adaptor interactions
• [ ] Verify tests run with rspec and integrate with existing .rspec configuration

Add unit tests for lib/volt/cli/ generator classes

The CLI module contains multiple generator classes (NewGem, Generate, Destroy, AssetCompile) that scaffold new Volt applications and components. These have no visible test coverage despite being critical user-facing functionality. Contributors can add tests for file generation, error handling, and template rendering.

• [ ] Create spec/lib/volt/cli/ test directory
• [ ] Add tests for lib/volt/cli/new_gem.rb covering project initialization and file creation
• [ ] Add tests for lib/volt/cli/generate.rb covering component/page/model generation
• [ ] Add tests for lib/volt/cli/destroy.rb covering safe deletion of generated artifacts
• [ ] Add tests for lib/volt/cli/asset_compile.rb covering asset pipeline compilation
• [ ] Test error cases (invalid names, permission issues, existing files)

Add missing documentation for server-side HTTP controllers in docs/

lib/volt/controllers/http_controller.rb and its submodule lib/volt/controllers/http_controller/http_cookie_persistor.rb exist but have no corresponding documentation file. The docs/ directory is sparse (only UPGRADE_GUIDE.md exists). Contributors can document the HTTP controller API, cookie persistence, and provide usage examples for server-side request handling.

• [ ] Create docs/HTTP_CONTROLLERS.md documenting lib/volt/controllers/http_controller.rb API
• [ ] Document HttpCookiePersistor in docs/HTTP_CONTROLLERS.md with persistence strategies
• [ ] Add code examples showing how to use HTTP controllers in server routes
• [ ] Document the relationship between ModelController and HttpController
• [ ] Add section on TemplateHelpers available in HTTP controllers (reference lib/volt/controllers/template_helpers.rb)
• [ ] Link new documentation from README.md

• Add missing test coverage for app/volt/models/volt_app_property.rb—currently untested; write specs for model validation and persistence behavior
• Extend app/volt/views/notices/index.html with comprehensive documentation showing all notice types and CSS classes available from notices.scss
• Create CLI command scaffolding in lib/volt/cli/ for generating new Volt components (model + controller + view template) analogous to Rails generators

• High · Outdated jQuery Library — app/volt/assets/js/jquery-2.0.3.js. The codebase includes jQuery 2.0.3 (app/volt/assets/js/jquery-2.0.3.js), which was released in 2013 and contains numerous known security vulnerabilities. jQuery 2.0.3 reached end-of-life years ago and has unpatched XSS and other attack vectors. Fix: Upgrade to the latest stable version of jQuery (3.6.x or higher) and ensure all dependencies are regularly updated. Consider using a dependency management tool to automate security updates.
• High · Potential XSS Vulnerability in Client-Side Code — app/volt/assets/js/volt_watch.js, lib/volt/controllers/template_helpers.rb. Volt executes Ruby code on the client side via Opal compilation. This architecture increases XSS risk if user inputs are not properly sanitized before rendering. The presence of volt_watch.js suggests DOM manipulation and dynamic updates that could be vulnerable if not properly escaped. Fix: Implement strict input validation and output encoding. Use a templating engine with automatic HTML escaping. Audit all user input handling in view templates and ensure proper use of Volt's sanitization methods.
• High · Insecure HTTP Cookie Handling — lib/volt/controllers/http_controller/http_cookie_persistor.rb. The HTTP cookie persistor implementation (lib/volt/controllers/http_controller/http_cookie_persistor.rb) may not properly handle secure cookie flags (HttpOnly, Secure, SameSite). Without these flags, cookies are vulnerable to XSS attacks and CSRF attacks. Fix: Ensure all cookies are set with HttpOnly and Secure flags. Implement SameSite cookie attribute (Lax or Strict). Review cookie persistence logic and validate against OWASP cookie guidelines.
• Medium · Potential SQL Injection in Query Tasks — app/volt/tasks/live_query/live_query.rb, app/volt/tasks/query_tasks.rb. The file app/volt/tasks/live_query/live_query.rb and app/volt/tasks/query_tasks.rb handle database queries. Without visible parameterized query usage or ORM abstraction in the file structure, there is risk of SQL injection if queries are constructed with user input. Fix: Ensure all database queries use parameterized queries or a robust ORM with automatic escaping. Avoid string concatenation for query construction. Conduct a code review of query construction patterns.
• Medium · Missing Security Headers Configuration — lib/volt/config.rb, app/volt/config/dependencies.rb. No evidence of security header configuration (CSP, X-Frame-Options, X-Content-Type-Options, etc.) in the provided file structure. This increases vulnerability to clickjacking, MIME sniffing, and other header-based attacks. Fix: Implement comprehensive security headers in the framework configuration: Content-Security-Policy, X-Frame-Options: DENY, X-Content-Type-Options: nosniff, Strict-Transport-Security, and X-XSS-Protection.
• Medium · No Visible Authentication/Authorization Framework — app/volt/models/user.rb, lib/volt/controllers/login_as_helper.rb. While user.rb and login_as_helper.rb exist, there is no clear evidence of comprehensive authentication mechanisms or role-based access control. The login_as_helper suggests potential for insecure impersonation if not properly restricted. Fix: Implement strong authentication using established libraries. Restrict impersonation features to administrators only with proper audit logging. Use multi-factor authentication for sensitive operations.
• Medium · No Dependency Lock File Detected — Gemfile (Gemfile.lock not provided). The security analysis requires a dependency file (Gemfile.lock or similar) to identify vulnerable gem versions. Without this information, transitive dependency vulnerabilities cannot be assessed. Fix: Ensure Gemfile.lock is committed to version control and regularly audited using 'bundle audit' or similar tools. Implement automated vulnerability scanning in CI/CD pipeline.
• Low · Polyfill Security Considerations — undefined. The volt_js_polyfills Fix: undefined
