Analysis

I've analyzed the PR changes:

R/reporter-progress.R: The main change is in the ParallelProgressReporter's end_file() method around line 482-496. When is_full() is true (max failures reached), it now:

1. Shows all collected issues from all files before terminating
2. Displays issues using the same pattern as the regular progress reporter

Snapshot changes: The test snapshots show that the parallel progress reporter now displays all 11 failures when hitting the max_fail limit, rather than terminating immediately.

Review

The code looks correct. The lambda function syntax \(x) x$issues$as_list() is consistent with existing usage elsewhere in the file (line 488). The change properly collects and displays all failures before terminating, which matches the PR objective.

LGTM

I think it is OK, I had two minor comments.
