Relay message envelopes are parsed but only honoured behind an off-by-default flag

Relay envelope routing is parsed but the flag deciding whether it counts as a human turn falls back to off.

What

Messages arriving through the projects relay (a Slack-style delivery path) can carry extra routing fields, which are always parsed and stored, but whether such a message counts as a real human turn is decided by tengu_hearth_resolved_rows, whose in-source fallback is "off". Only "full" or "model_only" are accepted; anything else stays off, and the telemetry reason flag_off is recorded.

Details
  • Fields accepted: up to 8 message ids matching /^cmsg_[A-Za-z0-9]{1,128}$/, a rows schema with author_kind of owner/member/agent/system, where of timeline or thread, plus thread_ts, written_at and truncated, and a thread timestamp.
  • They are persisted with the message, stripped by the same scrubber that removes the verified-Slack-turn marker, and change how the turn is presented to the model.
  • Nothing in this build sets the flag, so the real value comes from remote config.
  • None of these names exist in v2.1.238.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

What has happened since
Flag reading moved The flag server now returns "full" for tengu_hearth_resolved_rows, 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.
