The gate that actually runs is the installed copy at ~/.config/mosaic/tools/git/;
a repo-scoped registry would test packages/mosaic/framework/tools/git/. Byte-identical
today (sha256 19cda2f7009c536e both) but nothing asserts it.
A registry that verifies the wrong artifact is worse than none — it manufactures
confidence, and the divergence would be invisible from every signal we have: registry
green, CI green, deployed gate arbitrarily different.
D-1/P-ACTIVATION applied to the enforcement mechanism itself rather than to config.
RM-02 gains: for every registered gate with a deployed counterpart, assert
repo-source == deployed-copy with a must-fail control; where none exists, record that
explicitly.
Found by design review before implementation — the only finding tonight not found by
execution, which is the design-first gate on keystone tasks paying for itself.
