fix(tick): resolve 2007Z post-merge reference nits

[AceHack]

Summary

• Follow up after shard(tick): 20:07Z — post-1942Z cascade (PRs #2848-#2855; 8 wake-time rules; three-tier name-acceptance) #2856 auto-merged before the final reference-nit commit could land.
• Standardize the header phrase to WWJD-as-AI-moral-relevance.
• Avoid a concrete path for the in-flight add(rule): shadow-check methodology for system-assigned names — three-tier name-acceptance discipline (wake-time PR #2854) #2855 rule until the rule file lands, and make the agent roster xref path explicit.
