 ### Critical Quality categories
 
-`CodeQL Critical Quality` is the matching non-security shard. It runs only error-severity, non-security JavaScript/TypeScript quality queries over narrow high-value surfaces on the smaller Blacksmith Linux runner. Its pull request guard is intentionally smaller than the scheduled profile: non-draft PRs only run the matching `core-auth-secrets`, `channel-runtime-boundary`, `gateway-runtime-boundary`, `memory-runtime-boundary`, `mcp-process-runtime-boundary`, `provider-runtime-boundary`, `session-diagnostics-boundary`, `plugin-boundary`, `plugin-sdk-package-contract`, and `plugin-sdk-reply-runtime` shards for auth/secrets/sandbox/security code, channel runtime, gateway protocol/server-method, memory runtime/SDK glue, MCP/process/outbound delivery, provider runtime/model catalog, session diagnostics/delivery queues, plugin loader, Plugin SDK/package-contract, or Plugin SDK reply runtime changes. CodeQL config and quality workflow changes run all ten PR quality shards.
