Goal

• Turn the new health_snapshot_timing evidence into a concrete DevServer.health fix.

Evidence

• Live trace from the restarted shell showed:
  • health_snapshot_enter immediately
  • health_snapshot_timing with:
    • dirty_ms = 138162.33
    • hash_ms = 0.289
    • lock_wait_ms = 0.001
• That isolated the remaining delay to the shell dirty-state probe.

Change

• Replaced the unbounded shell dirty check with a bounded helper:
  • old path: git status --porcelain --untracked-files=all
  • new path: git diff --quiet and git diff --cached --quiet
  • both guarded by a timeout
• Added explicit shell_source_dirty_check reporting so live health responses can distinguish:
  • ok
  • timeout
  • git exit-code failures

Verification

• Targeted tests: passed
• Full suite: 173 passed

Next Step

• Restart the hot shell and re-run live DevServer(mode="health") to verify that the timeout is gone or at least degrades into a fast, diagnosable timeout-status response.
