A bounded memory-directory prefetch wait exists behind a flag with a false fallback.

What

Turn assembly can now wait on the in-flight memory-directory prefetch instead of proceeding without it, with the wait bounded and instrumented.

Details
  • The wait is a 2000 ms race with abort-signal support.
  • Reports outcome as consumed, deadline or aborted, along with how long it waited and how many attachments arrived.
  • Gated on tengu_mill_orange with fallback !1, and additionally requires the org-memory decision to not be undecided.

Feature flag
tengu_mill_orange 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.

What has happened since
Flag reading moved The flag server now returns off for tengu_mill_orange, 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.
