Read back from the registry rather than inferred from a green Action:

    {"published": true, "version_seen": "0.16.46", "latest_seen": "0.16.46"}

Host channel refreshed separately from the repo one: the marketplace clone at ~/.claude/plugins/marketplaces/prd-plugin reset to origin/main and reads 0.16.46, and `claude plugin update` moved the user-scope install from 0.16.45 to 0.16.46.

Carries REQ-155 (completed by REQ-158), REQ-158, REQ-159, REQ-160, REQ-161 and REQ-163. REQ-162/HLT-021 remain open by design: the gate still cannot see whether changed source has a test.
