I'll review the changes for making WAL apply lag metrics persistent across restarts. Let me examine the code changes first.

🏁 Script executed:

#!/bin/bash
# Get the PR diff to understand what changes were made
git diff HEAD~1..HEAD

# Also get the full content of the modified files to understand the context
echo "=== SeqTxnTracker.java ==="
cat io/questdb/cairo/wal/seq/SeqTxnTracker.java

echo "=== WalMetrics.java ==="
cat io/questdb/cairo/wal/WalMetrics.java

echo "=== TableSequencerAPI.java ==="

Let me explore the repository structure to find the correct file paths and examine the changes.

🏁 Script executed:

#!/bin/bash
# First, let's see the repository structure
echo "=== Repository root contents ==="
ls -la

# Find all Java files related to WAL or metrics
echo "=== Finding WAL and metrics related files ==="
fd -e java | grep -i wal
fd -e java | grep -i metric

# Look for the specific files mentioned in the coverage report
echo "=== Searching for SeqTxnTracker ==="
fd "SeqTxnTracker.java"

echo "=== Searching for WalMetrics ==="
fd "WalMetrics.java"

echo "=== Searching for TableSequencerAPI ==="
