docs: Claude Code v2.1.270 - regression fix for git permission prompts + Claude Tag 👎 muting feature

[claude-yolo]

Night shift report

WHY THIS MATTERS: v2.1.270 is a same-day hotfix for a regression shipped in yesterday's 2.1.269 — sessions running long enough would see read-only git commands (e.g. git status, git log) start prompting for permission even though they never needed it before. That's the kind of silent papercut that breaks trust in the tool, and it got a standalone release inside 24 hours. Also new: Claude Tag (Slack) now documents thumbs-down muting as an explicit feature — 👎 on any Claude reply mutes the thread and stops an in-flight response mid-generation. That behavior existed but was undocumented; admins were seeing "Claude went silent" bug reports for what was actually working-as-designed.

HIGHLIGHTS:

• Regression fixed (2.1.270): Read-only git Bash commands were prompting for permission unexpectedly after a session had been running a while — introduced in 2.1.269, fixed same day.
• Claude Tag: 👎 = mute (newly documented): A thumbs-down reaction on any Claude reply now mutes that thread and abandons any in-progress reply. Claude posts a :mute: notice. @Claude !unmute or any @Claude mention reverses it.
• Troubleshooting updated: The admin "Claude went silent" guide now differentiates a stuck session from a muted thread — admins should check for the :mute: notice before assuming a session is broken.
• discovery.json and tombstones.json — timestamp-only changes, no new sources, no page deaths or resurrections. Clean run.
• 60+ support articles refreshed (minor wording/formatting), no deletions.
