CI for csaxs_bec / test (push) Successful in 1m48s
Read-only analysis of BEC master files, to test two user reports from the 15-20 July commissioning beamtime without needing beam. **End-of-line intensity** (Andreas Apseros): reshapes each monitored signal into lines and reports the last point and the first point against the interior mean. It only calls it the reported bug when the *last* point is short and the first is not -- if both ends are low that is a different mechanism, and the script says so rather than confirming what we went looking for. **Dropped line motion** (Kazu Hirosawa's reading, that the stage intermittently stopped scanning in one direction): reshapes the fast-axis readback and reports the travel per line. A collapsed span is motion that did not happen while the scan still reported success -- the same shape as the silent-completion defects already recorded against ccm_energy and the ECMC limit writes. It also reports start/end scatter per line, since scatter at one end only would instead point at the return move racing the next line. Verified against synthetic files with both artefacts injected and a clean control. That test caught a real flaw in the first version: the fast axis was picked by within-line range, and a noisy diode channel out-ranged the axis and was selected instead, breaking both checks. It now scores signals by how monotonically they ramp within a line, which separates an axis from an intensity regardless of scale. Lives on a debug branch, not main: it is a diagnostic for one investigation, not plugin code. bin/debug/README.md says what that means. Caveat carried in both the docstring and the README: the motion check reads the readback, so on an open-loop stepper without an encoder a healthy span proves nothing. That is the same question as Ana Diaz's micro-stepping point and needs settling before the null result means anything. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
