+# First build entry = v2.7.4, the first release that BOTH disables AGP VCS-info
+# (`vcsInfo { include = false }`, since v2.7.3) AND drops the unused Gradle
+# foojay toolchain-resolver plugin, which F-Droid's offline build scanner rejects
+# (it can fetch a JDK over the network). The plugin was inert here (no toolchain
+# block invoked it), so v2.7.4 is functionally identical to v2.7.3 and reproduces
+# byte-for-byte from source. v2.7.3 and earlier either embed
+# META-INF/version-control-info.textproto or trip the foojay scanner — do not
+# target them. Subsequent versions are added automatically (AutoUpdateMode).
