Brainstormed design for adding the SPDX-CMSD-1.0 header to every
first-party source file (~2,170 across 6 languages), backed by a
reusable Python tool (scripts/license-headers.py), a CI check, and
a phased per-package rollout. Spec covers scope, header rendering
per language, placement rules, tool architecture, CI integration
with an enrollment allowlist, and verification steps.
