+# Ship every release binary stripped. Production already builds without -g, but
+# the linker still keeps a ~536 KB .symtab, so releases carried their full
+# symbol table to users: bigger downloads and a free map of the internals, with
+# nothing gained. Nothing symbolizes at runtime (mem_profile.c is not in the
+# production build and never calls backtrace_symbols), so this costs no
+# diagnostics.
+#
+# It also had a concrete cost. Microsoft's ML scored the unstripped linux-amd64
+# binary Trojan:Script/Wacatac.B!ml (1 engine of 62) and blocked release run
+# 30398064336 at the VirusTotal gate. That verdict is a decision-boundary
+# artifact rather than a property of the code -- the dry-run build two days
+# earlier is the same program plus 10 KB and scans clean, and the ui build of
+# the same commit was never flagged. Stripping removes the symbol surface those
+# models score and cleared BOTH flagged builds (Wacatac.B and Wacatac.C)
+# without changing what the program does.
+#
+# macOS is ad-hoc signed by the build workflow BEFORE this script runs, and
+# stripping invalidates that signature, so Mach-O is re-signed here. Skipping
+# the re-sign ships a binary the kernel refuses to exec.
