Problem

The upm package manager was added to benchmarks in #177 but its count file entries were missing from the collector scripts. This caused upm to appear inconsistently on benchmarks.vlt.sh:

• ✅ Shows in the Total Install Time histogram (uses raw chartData)
• ✅ Shows in the Tools dropdown
• ❌ Missing from Leaderboard cards (uses perPackageCountChartData)
• ❌ Missing from Per-Fixture horizontal bar charts (uses per-package data)

Root Cause

The data pipeline for per-package metrics works as follows:

1. package-count.sh runs after each benchmark → correctly detects upm.lock and writes upm-count.txt ✅
2. collect-package-count.js reads *-count.txt files into package-count.json → missing upm-count.txt entry ❌
3. generate-chart.js uses package counts to compute per-package times → no count for upm → no per-package data
4. App leaderboard and per-fixture views use per-package data → upm excluded

Same issue exists in collect-process-count.js for spawned process counts.

Fix

Add the missing entries:

• { filename: 'upm-count.txt', pmName: 'upm' } to collect-package-count.js
• { filename: 'upm-process-count.txt', pmName: 'upm' } to collect-process-count.js

The next benchmark run on main will produce correct per-package data for upm, and it will appear in all views.

📝 Walkthrough

Walkthrough

The package-count and process-count collectors now include UPM count files in their existing collection flows. Both files map to the upm package-manager name.

Changes

UPM Count Collection

Layer / File(s)	Summary
Add UPM count inputs scripts/collect-package-count.js, scripts/collect-process-count.js	The collectors recognize upm-count.txt and upm-process-count.txt, respectively, and associate each with upm.

Priority: ⬇️ Low
