A new gated flag controls session create/read/update/delete support for CCR v2 in the CLI's MCP bootstrap

What

The MCP (Model Context Protocol) client bridge's periodic status-announce call now includes a new flag, ccrV2SessionCrudEnabled, read from a setting called tengu_ccr_v2_session_crud_cli. This flag is forwarded downstream under the same name.

Why

This wires up a gate that controls session create/read/update/delete behavior for a system referred to as CCR v2, but does not itself describe what that behavior changes.

Feature flag
tengu_ccr_v2_session_crud_cli Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.277: off

What has happened since
Flag reading moved The flag server now returns on for tengu_ccr_v2_session_crud_cli, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
