The CI duration monitor folded the "Prepare breeze & CI image" step into each job's total. That step occasionally balloons on a one-off cache miss (a full image rebuild instead of a cached pull), which repeatedly flagged unrelated jobs as regressed — e.g. a Non-DB core job reported +190% driven almost entirely by an 18m image build, while its actual test time was flat. Image-build time is now excluded from the run and per-job durations used for the trend, and the image build is watched on its own: it is only reported when it has stayed slow for more than two days (`IMAGE_BUILD_PERSISTENCE_DAYS`, default 2), so a transient rebuild spike no longer produces a false alert. ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Opus 4.8) Generated-by: Claude Code (Opus 4.8) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
