SESSION_PINNED is checked via two feature-flag lookups. One of them, tied to the tengu_gentle_frost flag, now first runs an additional environment check (le()) before it queries the remote feature-flag server at all, whereas previously it queried the flag unconditionally.
This narrows when Claude Code even bothers asking the flag server about this particular tengu_gentle_frost variant, likely to skip the remote check in environments where it wouldn't apply anyway.
