Engagement disposition: engaged. This remains a real external human gate. I verified the repo records why ORCID matters, but I found no ORCID identifier/registration receipt in aerarium--res-publica main. Because ORCID registration is an account/identity action, the correct next step is still the human registration/receipt, not an automated repo mutation.
