Checkpoints now record self-scheduling wake counts and open artifact watches, though the loop itself is off.

Loop state survives handoff, but the loop is behind tengu_kairos_loop_dynamic, which falls back to false.

What

Session checkpoints now record how many times a self-scheduling loop has woken and what live Artifact watches were open, and each scheduled wake-up records when it is due, why, and whether it holds a keepalive budget. The loop feature itself is behind tengu_kairos_loop_dynamic, whose in-source fallback is false, so it is off absent a server value.

Details
  • The wake count is stored as a non-negative integer, so a loop's wake budget carries over instead of resetting when the session is handed off to the background.

tengu_kairos_loop_dynamic Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

Flag reading moved The flag server now returns on for tengu_kairos_loop_dynamic, 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.
