Every feature flag, and where it lived

55 of 2,081 feature flags One tick per build on this box, oldest on the left. A gap is a build the feature flag was not in.

A is the one account this site reads, N the anonymous baseline, D what the release compiled in. 1,143 of 2,081 gates have been read at all: a run only records the gates its own release wrote about. Claude Code evaluates its gates on Anthropic's servers, so a reading of off can be a rollout this account sits outside of, and none of it says anything about your install. How to read these.
