Terminal-escape scrubbing for grader summaries, inside the early-access plugin eval command.

What

Read once, for one account on one subscription tier, against v2.1.233. It isn't a statement about your account. What a flag value here can and cannot tell you

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