summary

Builds a native histogram rendering with HTML/CSS/JS, lands two PRs after four months of work, and fixes exponential-axis scaling, overlapping buckets, overflow and the tricky zero-bucket edge case. Implements OpenMetrics created-timestamp parsing by making a deep copy parser peek ahead to locate CT, which works functionally but raises memory per line/per scrape; adds microbenchmarks and aims to replace the peek approach with a memory-efficient CT parser and complete a heat map view.
