This thresholds file declares itself auto-generated and says not to edit it manually; changing only this one bound from the generated CI_bound / (1 ± 10%) value means check-slo-breaches will now allow normal_operation--profiler-win p95 latency up to 38.23 ms even though the recorded upper CI generated the previous 36.23 ms limit. That masks real profiler regressions in the 36.23-38.23 ms band and leaves the generated metadata/comments inconsistent, so this should be regenerated with the benchmark analyzer or handled through the documented bypass flow.

Execution-Time Benchmarks Report ⏱️Execution-time results for samples comparing This PR (8545) and master. ✅ No regressions detected - check the details below Full Metrics ComparisonFakeDbCommand
HttpMessageHandler
Comparison explanationExecution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:
Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard. Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

Summary of changes
Reason for change
We're getting intermittent warnings and failures, but it doesn't look "real", and there's serious alert fatigue happening.
Implementation details
Manually bump the SLO for now, because I don't have an easy way to regenerate suggested values. Just picked a random number. And disabled the notifications
Other details
We should set up a way to handle this more cleanly (e.g. like this), but right now I just want to make the alerts stop
