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.

tengu_xterm_atlas_reset ◇ Default true. Enables proactive glyph atlas resets in the terminal renderer on xterm.js terminals: once 2000 distinct styled glyph keys have been recorded (and 2000 ms have passed since the last reset), and when the terminal regains focus, Claude Code writes the escape sequence \x1B]104;255\x07 and clears its glyph record. When off, glyph recording also stops unless tengu_basalt_meadow is on.v2.1.154 → v2.1.308 ◆in the build AND v2.1.308
tengu_zippy_gosling ◇ Default 0 (off). Idle threshold in milliseconds for an interval poller used by several background checks, including policy limits polling. When it is a positive number, no main-loop query is running, and more time than that has passed since the later of the last user interaction and the last API completion, a poll tick is postponed until the next user interaction, at most 3 ticks in a row; a non-number, zero or negative value turns the postponement off.v2.1.261 → v2.1.308 ◆in the build AND v2.1.308
