A session is one run of Claude Code from start to finish.\n\n- `tengu_ccr_stream_flush_on_first_delta`: the switch is ignored. Claude Code now always behaves as if it were off.\n\n- `tengu_ccr_replay_acks_at_request_dispatch`: the switch is ignored. For that connection type, acknowledgements are now always replayed when a request is sent.\n\nBoth switches used to fall back to off when the server sent nothing. In readings taken before this release, the server was returning on for both on this site's account.\n\n**Why**\n\nReplaying acknowledgements at request time used to be off unless switched on remotely. For this connection type it is now always on, and a server setting can no longer turn it off.\n\n- Flag `tengu_ccr_replay_acks_at_request_dispatch`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.301; this account: on, anonymous baseline: on, compiled default: not a boolean we can read) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Flag `tengu_ccr_stream_flush_on_first_delta`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.301; this account: on, anonymous baseline: on, compiled default: not a boolean we can read) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Sessions\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
