1.3.0-alpha2: forward-port of 1.1.0-alpha2 fixes onto vary-cookie baseline First public alpha of the 1.3.x track. Same vary-cookie response subscriber additions and config schema as the never-tagged 1.3.0-alpha1, plus the two response-subscriber correctness fixes from 1.1.0-alpha2 brought forward via merge of 1.2.x (which itself merged 1.1.x): - Admin routes no longer emit any LSCache header. - Debug log messages contain resolved values inline. 1.3.0-alpha1 was implemented and CI-validated but never tagged or released, since the alpha1 field-test loop ran on 1.1.x first. 1.3.0-alpha2 is the first public alpha of the 1.3.x track.
