handshake-protocol-kernel 0.2.7

0.2.7 is the npm page cleanup and release-administration release for the published package artifact boundary.

The npm package is available with trusted-publishing provenance and installed-artifact smoke evidence. Public npm availability does not create authority, policy decisions, greenlights, gateway checks, mutations, hosted operation, or MCP Registry discoverability.

MCP Registry discoverability remains the remaining distribution proof gap.
