[Bug] CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS=1 has no effect on git subprocess polling on Windows
Bug Description
CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS=1 does not reduce git subprocess polling in interactive sessions (Windows 11, claude.exe from ~\.local\bin).
Two interactive sessions in the same repo (a large monorepo), same scripted load (20 Read/Grep calls looped for 600 s, no Bash, no agents). One started
with the variable set to 1 (verified via os.environ inside the session), one unset.
Direct git.exe children of each claude.exe over 600 s: unset 1,163; set 1,164. Direct conhost.exe children: 773 vs 766.
Commonest subcommands across the sample: status, remote, rev-parse, config, symbolic-ref, update-index, write-tree, often at ~0.1 s spacing.
Expected: setting the variable stops the background git calls. Actual: no change. Is there a setting that disables the git status/branch polling, or is it
unconditional?
