tengu_ember_latch falls back to off, hiding a surface that previously showed.

What

A limits-related interface that previously showed for Pro and Max accounts is now wrapped in an additional check tied to the tengu_ember_latch feature flag. Nothing in this build sets that flag, and it falls back to off, so the surface stays hidden unless server config enables it.

Details
  • The Pro/Max account condition still applies underneath the new outer check.
Evidence

tengu_ember_latch

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Feature flag
tengu_ember_latch 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_ember_latch, 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.
