Summary by CodeRabbit

• Improvements
  • Agent connection summaries now preserve IPv4 and IPv6 addresses consistently, including after registry reloads.
  • WebSocket connection requests without an available peer address now return an error instead of relying on forwarded headers or an “unknown” address.
• Developer Tools
  • Added automated checks for code rules, including a check against Unix-domain-socket HTTP listeners.
  • Updated the documented total of custom checks and rules.

📝 Walkthrough

The changes use typed IP addresses across WebSocket and WIT messages, add a rule against Unix-domain HTTP listeners and test tasks for static-analysis rules, and define a Pyodide module path.

Changes: Typed IP address flow

Layer / File(s)	Summary
IP address WIT contract utilities/int-gen/src/error.rs, utilities/int-gen/src/wit/messages.rs, services/ws-wasi-runner/src/bindings.rs	WIT generation maps IP-formatted strings to an IPv4/IPv6 variant. Conflicting client and server definitions now return an error. The generated bindings include the address variant.
Peer IP capture and registry storage libs/edge-toolkit/src/ws.rs, libs/edge-toolkit/src/ws_server.rs, services/ws/src/connection.rs, services/ws/src/lib.rs, libs/edge-toolkit/tests/registry.rs, services/ws/tests/load_registry.rs, services/ws/tests/ws_handler.rs, services/storage/tests/*, services/ws/Cargo.toml, config/jscpd-baseline.json	The WebSocket handler uses the socket peer IP and returns an internal-server error when it is unavailable. Registry records and summaries use IpAddr. Tests cover typed addresses, registry round trips, and handler responses.
WIT address conversion services/ws-wasi-runner/src/host/ws.rs, services/ws-wasi-runner/tests/server_message_to_wit.rs	The host converts agent addresses to WIT IPv4 or IPv6 variants. Tests check both forms and their values.

Static-analysis rule checks

Layer / File(s)	Summary
Unix-domain listener rule and cases config/ast-grep/rules/no-uds-listener.yaml, config/ast-grep/tests/no-uds-listener.yaml, CHECKS.md	A new rule flags bind_uds and listen_uds calls. Its cases cover TCP and Unix-domain listener methods.
Rule-test tasks and check documentation .mise/config.toml, AGENTS.md, CHECKS.md, README.md	Mise adds ast-grep and Semgrep rule-test tasks to check:rust. The guidance and check documentation describe rule testing and updated check totals; the README badge threshold is now >=340.

Pyodide module path

Layer / File(s)	Summary
Pyodide module path constant services/ws-modules/pydata1/pkg/et_ws_pydata1.js	The module defines PYODIDE_CDN as a path under PYODIDE_BASE_PATH and documents the browser and non-browser entry paths.

Merge Risk: 🟡 Moderate · up to da204

Making the agent IP mandatory means a registry saved by the current release, which may contain missing or "unknown" addresses, no longer loads on restart. WebAssembly guests built against the previous message interface may also stop working until they are rebuilt. Add a migration for old registry records, and coordinate a versioned interface or a guest rebuild, before merging.

Review comments at @libs/edge-toolkit/src/ws_server.rs:
- Line 94: Update AgentRegistry::load and load_registry to migrate legacy IP
values before deserializing records into the new IpAddr fields: handle YAML null
and the "unknown" fallback according to a consistent migration policy while
preserving valid IP addresses. Add reload coverage for both loading paths that
verifies registries containing each legacy value load successfully.

Review comments at @services/ws-wasi-runner/src/bindings.rs:
- Line 416: Update the WIT interface containing `last_known_ip` to preserve the
existing `option<string>` contract for guests compiled against
`et:ws-messages@0.2.0`; expose the new `ip-address` type through a versioned
interface, or coordinate guest rebuilds and migration before changing the
existing contract.
