CLAUDE_ENABLE_STREAM_WATCHDOG
A Claude Code environment variable, read out of the shipped bundle. It was in the build from v2.1.138 and was gone by v2.1.242.
What it is
Five more environment variables, including stream and byte watchdogs, can be set in settings.json.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.248.

A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.
