--debug will allow logging of the start/end of block processing on each indexer (and any other debug logs)

Pre-submit checklist:

• Branch
  • Tests are provided (if possible)
  • Commit sequence broadly makes sense and have useful messages
  • Important changes are reflected in changelog.d of the affected packages
  • Relevant tickets are mentioned in commit messages
• PR
  • (For external contributions) Corresponding issue exists and is linked in the description
  • Targeting main unless this is a cherry-pick backport
  • Self-reviewed the diff
  • Useful pull request description
  • If relevant, reference the ADR in the PR and reference the PR in the ADR
  • Reviewer requested

The code changes look good to me, and the app gives the expected output when run locally with the new flag.

Unsure what's up with the golden files test failures, except possibly whitespace issues.

[berewt]

I don't know either, the tests pass locally... So yes, likely an issue with the golden value. Maybe the golden-files whitespace has been trimmed...

I don't know either, the tests pass locally...

Oh interesting. They fail for me locally.

Might have found the issue while puzzling over the difference:

By using cat -A on the CLI output vs. golden files, I see the CLI output has a Windows style \r\n newline character at the end of each line. The golden files don't.

[berewt]

We should have a golden file space insensitive mode... Can you accept the golden test values and push the corresponding commit? cabal test all --test-options=--accept
