chore(build): bump Go toolchain 1.23.2 -> 1.26.7 - #373
Merged
Conversation
Step 2 of the CVE-cleanup plan. The released fizzbee binary embedded go1.23.2 (~2 years old; the 1.23 line is past end-of-life, so Go stdlib security fixes no longer reach it). 1.26.7 is the latest patch of the currently-supported previous stable line — deliberately not 1.27.0, which shipped days ago. No scanner currently flags the old toolchain (docker scout reports zero Go findings against the release binary), so this is hygiene rather than an urgent fix — but unlike the rules_python refresh (deferred: cross-compile breakage), a Go toolchain swap is low-risk and fully verifiable. Verified: reference suite 98/98; cross-builds pass for linux_x86, linux_arm, macos_x86 (macos_arm is the native build host); the resulting binary embeds go1.26.7.
