codebase-memory-mcp/scripts/package-release.sh

#!/usr/bin/env bash
# package-release.sh — THE canonical release-archive step. Every venue that
# turns built binaries into a release archive (release/_build.yml, the local
# artifact-flow smoke lane) runs this file; workflows provide only
# checkout/toolchain/upload around it. Archive names and contents are defined
# HERE, nowhere else, so a local artifact smoke provably exercises the same
# bytes-layout the release publishes.
#
# This script ARCHIVES what scripts/build.sh already produced — it never
# builds the product itself (the Windows launcher image is the one deliberate
# exception: it is part of the archive, not of the product build).

Usage: scripts/package-release.sh <goos> <goarch> [--variant standard|ui]
                                  [--out-dir DIR] [VAR=VAL ...]

The canonical release-archive step: identical in the release build and the
local artifact-flow smoke lane.

  goos       linux | darwin | windows
  goarch     arch label used verbatim in the archive name (amd64, arm64,
             arm64-portable, ...)
  --variant  standard (default) | ui — selects the archive NAME prefix; the
             matching binary must already have been built (--with-ui for ui).
  --out-dir  where to place the archive (default: repository root).

Make passthrough (VAR=VAL, forwarded to the build):
  CC= CXX=   compiler override, e.g. CC=clang CXX=clang++.

Environment:
  BUILD_DIR  build tree to archive from (default build/c).

Archive contents (defined here, canonical) — ONE binary per platform:

# 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.
