What
Claude Code's internal list of telemetry and event identifiers has grown substantially, now covering areas like agents, artifacts, the bridge, ccr, MCP, sandboxing, self-hosted runners, and workflows. Alongside this, new internal constants define standard event sources (slash_command, cli_flag, startup, tool, dispatch, cloud_session) and denial reasons (org_denied, cache_miss, route_missing), and a new pattern now requires permission rule names to start with allow_ followed by lowercase letters, numbers, or underscores.
Why
This is mostly internal bookkeeping that expands what Claude Code can track and validate; the permission-rule-name pattern in particular tightens what counts as a valid rule name.
