Summary of changes

As we continue to try and refine CODEOWNERS we are running into the limitation that we choose what tests to run based on who owns what. Instead this attempts to re-encode this

Reason for change

Our CI uses CODEOWNERS to determine what tests to run on a given PR. This isn't ideal as it means we are limited when trying to update team ownership. This attempts to address that.

Implementation details

Removes the coupling between CI and CODEOWNERS, with some basic file paths and "area" paths that match our pre-existing ones.

Test coverage

Other details

I expect that some PRs will get hit with additional test runs, we will monitor this and work on refinement.

Benchmarks

Benchmark execution time: 2026-10-09 16:23:43

Comparing candidate commit 0a3130c in PR branch steven/decouple-codeowners-and-building with baseline commit a5a4fa8 in branch master.

📊 Benchmarking dashboard

Found 0 performance improvements and 13 performance regressions! Performance is the same for 59 metrics, 0 unstable metrics, 76 known flaky benchmarks, 50 flaky benchmarks without significant changes.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

  • 🟩 = significantly better candidate vs. baseline
  • 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'
