The GLMZ Civic Compact formalized five citizenship tiers, each conferring different levels of legal standing, access to services, freedom of movement, and protection from corporate enforcement actions. Tier-1 affiliates of the major corporate sovereigns — NovaClarent, Axiom Logistics, the Drexler-Vance Consortium — possess something that functionally resembles full legal personhood as it was understood in the pre-Compact municipal era. Tier-5 residents, classified as 'unaffiliated residuals' and concentrated in the Canal District and the outer Westfield warrens, possess a legal status that many philosophers argue is closer to the Roman category of the peregrinus than to modern citizenship: present within the territory, subject to its enforcement mechanisms, but without the reciprocal protections that define membership.

The philosophical literature on tiered personhood has become one of the most contested fields in GLMZ's intellectual life, in part because the stakes are not merely theoretical. The question of whether Tier-5 residents possess the same fundamental moral status as Tier-1 affiliates is answered differently by the legal frameworks governing corporate enforcement, the resource allocation algorithms that determine which neighborhoods receive infrastructure maintenance, and the AI sentencing advisory systems that weigh civic tier as a variable in risk assessment. That these systems operationally treat tier as a proxy for moral worth is not a secret; it is, in many cases, explicitly designed policy.

Philosophers who have attempted to articulate a principled defense of tiered moral consideration — a minority, but not an absent one — tend to ground their arguments in contractarian frameworks. If moral standing derives from participation in a cooperative scheme of mutual benefit, and if Tier-5 residents have not entered into any formal cooperative agreement with the governing institutions of the megacity, then the obligations those institutions bear toward them may be genuinely weaker, though not absent. This argument is advanced most carefully by the Drexler-Vance Corporate Ethics Division's in-house philosopher-in-residence, whose published papers on 'graduated obligation frameworks' are simultaneously cited by corporate governance departments and excoriated by civil society scholars as philosophical cover for administrative brutality.

The dominant counter-position, articulated most powerfully by the collective of scholars associated with the Canal District Peoples' Faculty, grounds moral status in vulnerability rather than participation. On this view, the fact that Tier-5 residents are more exposed to harm — from corporate enforcement, from environmental contamination in the unventilated lower levels, from algorithmic denial of medical resources — is precisely what generates stronger, not weaker, obligations toward them. This vulnerability-centered framework draws on a long tradition running from feminist ethics of care through Judith Butler's precarity theory, but its application in GLMZ has been sharpened by the specific material conditions of the megacity. The Canal District Faculty's 'Precarity Index' — an annual report quantifying the specific harms experienced at each citizenship tier — has become one of the most cited documents in GLMZ's civil society discourse, and one of the most suppressed.
