Abstract
Towards the high luminosity (HL) operation of the Large Hadron Collider (LHC), the inner tracking system of the ATLAS detector will be replaced by a fully silicon-based inner tracker (ITk).Its outer region consists of 17,888 n + -in-p silicon strip sensors.In order to confirm key properties of the production sensors as well as to establish a solid workflow of quality inspection and monitoring of the various sensor properties, about 5% of the total strip sensors were produced in 2020 as a preproduction run.As a quality assurance (QA) program, irradiation of dedicated QA test pieces was periodically performed.The fluences of proton, neutron and -ray irradiations were up to 1.610 15 1-MeV neutrons/cm 2 and 0.66 MGy, which are equivalent to the maximum expected radiation fluences at the HL-LHC operation with a safety factor of 1.5.Results from 154 QA test pieces demonstrated high quality of the strip sensors through the pre-production.Detailed understanding of post-irradiated strip sensors was acquired, and the procedures of irradiation and post-irradiation QA testing were fully established.Consequently, the 3.8-year project of the strip sensor production for the ATLAS ITk detector was initiated in July 2021.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
