feat(ri-050): bind next publication to exact-commit terminal verification (#1275)

Reviewed by scooby via git comms (terminal ACK 32d986). Merge directed by Jason 2026-08-16. Conflicts from #1229 and #1252 resolved on the branch by a pi seat; pre-merge gate verified: tools/install.sh=5d28f773, framework/install.sh=1578c33b, test:framework-shell=48 links with both #1252 and #1245 suites present.
