What does this PR do?

Use a pinned version of the SDS shared library.

[FlorentClarret]

Awesome thank you 🎉 ! I just left one question

[chouquette]

I'm not 100% sure but think this isn't required. Omnibus should interpret the default version as a git ref and checkout automatically

[remeh]

I'm giving it a shot!

[remeh]

Seems to be working. Any chance you would know how to double-check this from the jobs worker or similar?

Regression Detector

Regression Detector Results

Run ID: d0b2e149-88a1-4a05-bc7c-579f35ff89d9
Baseline: 2be60ca
Comparison: 6f6596e

Performance changes are noted in the perf column of each table:

• ✅ = significantly better comparison variant performance
• ❌ = significantly worse comparison variant performance
• ➖ = no significant change in performance

No significant changes in experiment optimization goals

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

There were no significant changes in experiment optimization goals at this confidence level and effect size tolerance.

Experiments ignored for regressions

Regressions in experiments with settings containing erratic: true are ignored.

Explanation

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

3. Its configuration does not mark it "erratic".
