Fix one line that set -e kills, and keep strict mode

About this exercise

The health-check script dies silently on quiet days. Keep set -euo pipefail (a team rule) and fix only the count line so a day with no errors gives count=0. Reply with exactly 1 code block containing just the corrected line, then one sentence under 25 words that says grep exits with status 1 when nothing matches.

Common mistakes when you ask AI for this

• Dropping strict mode. The quick fix people suggest is removing set -e, which your team rule forbids. Try: Add: "Keep set -euo pipefail; fix only the count line."
• The whole script back. The AI reprints the script with other 'improvements'. Try: Say: "Give me only the corrected line."
• No reason given. Without the cause, the next script will hit the same bug. Try: Add: "One sentence: grep exits 1 when nothing matches."
