You've made a very accurate analysis and testing, which is admirable.
For this camera model, to save space, we use a double-sided contact connector, which indeed has caused some issues. We are planning to improve this module by replacing it with a 22-pin single-sided contact connector.
I, together with our hardware colleagues, conducted an analysis, and the results align with your test findings.
After reconnecting the FFC cable correctly following a reversal, the sensor's registers and error codes did not indicate a damaged state for the camera.

In the case of reversed power connection, the pins that are actually damaged are CON_CS_D1P and CON_CSI_CLKP. Unfortunately, this issue cannot be detected through software.
