Over the weekend we've been having some trouble with low ALSX beatnote and other ALS issues causing locking trouble (See 74310, 74289). There was also a XVEA temperature change that happened Friday evening (picture here). Looking back at past changed of the ALSX laser we have June 30th alog70976 which had similar symptoms and was maybe fixed with a laser current and temperature change. Before that in Aug 2022 Daniel (alog64752) did a similar fix.

Plots attached have a dozen ALSX channels trended over 3.5years, 2years, 21 months, 65 days. The only bit that stands out to me is that the green power has started to trend down ~20 days ago, but it's a small amount (0.83 -> 0.80mW).
