# Improve Metric Accuracy for Issues, PRs, and Review Distribution

Browse Source 
## 1. What the change is
This PR refactors the `open_issues.ts` and `open_prs.ts` metric scripts to use the GitHub GraphQL API's `totalCount` field instead of relying on the CLI's `gh issue list` command with a hardcoded limit. It also updates `review_distribution.ts` to include `COLLABORATOR` in the maintainer association check.

## 2. Why it is recommended
The current implementation of `open_issues.ts` and `open_prs.ts` used `--limit 1000`, which caused metrics to be capped at 1000 even when the actual backlog was much larger (~2400 issues). This provided a misleading view of repository health and the true scale of the backlog. Using GraphQL `totalCount` ensures accurate counts regardless of list size.

Additionally, `review_distribution.ts` was inconsistently excluding `COLLABORATOR` associations, which could lead to an inaccurate representation of review work distribution if many maintainers are designated as Collaborators. This led to a `review_distribution_variance` of 0 in recent runs.

## 3. Which metric or aspect of productivity is expected to be improved
- **open_issues**: Will now reflect the true total count (expected to jump from 1000 to ~2400).
- **open_prs**: Will reflect the true total count of open pull requests.
- **review_distribution_variance**: Will more accurately reflect how review work is shared among all maintainers (including collaborators).

## 4. By how much the metric is expected to improve
The `open_issues` metric is expected to increase by approximately **140%** (from 1000 to ~2400) once accurate data is collected. The `review_distribution_variance` is expected to become non-zero, providing a real baseline for monitoring reviewer workload balance.
