§ 04 · AS-P04
Constitutional reversibility
No contract should make a sovereign decision irreversible.
Statement
No technological system should be adopted if its reversibility — the real capacity to exit, change provider or modify the logic — is not guaranteed within a politically significant horizon, ideally five years. Reversibility is a constitutional guarantee, not a procurement clause.
Why it matters
Critical technological systems outlive the governments that adopt them. When an administration signs a contract with a vendor that produces fifteen-year technical dependence, it is mortgaging the decision-making capacity of the next three administrations. This is democratically problematic even when the initial decision is correct: the next elected government can inherit an operational apparatus it did not decide, cannot modify and cannot reverse without operational collapse. Reversibility is not paranoia: it is the condition that allows democracy to keep functioning under accelerated technological modernization.
Operationalization
Every state-scale technology adoption decision or critical infrastructure decision must pass a formal reversibility evaluation before contract signing, not after. The evaluation includes four conditions: technical data portability guaranteed in open formats (not just contractually declared); independence from proprietary formats for critical processes; demonstrable availability of at least two providers capable of operating the system under equivalent conditions; and local technical capacity — human, not contractual — to operate the system in an exit scenario. If any of the four conditions is not met, adoption must be redesigned or postponed. This evaluation must be public, auditable, and applicable also to the private sector for critical infrastructures (banking, health, telecommunications).
Named tension
Reversibility costs — more upfront diligence, anticipated migration costs, more demanding terms with the vendor. Whoever signs short-term pays less today and far more the day after the first vendor switch.
Interdependence · Interdependence with Principle 5 — Endogenous productive density
Reversibility is only real when it coexists with endogenous productive density. A contractual exit clause without local people capable of operating the replacement system is theatrical reversibility: the contract says you can exit, but the technical ecosystem doesn't allow building an alternative. Technical data portability and human capacity to do something with it in case of migration are inseparable conditions.
Applied example
A well-negotiated AI MSA specifies rights over fine-tunes, embedding portability, and log jurisdiction. The same contract without those clauses turns the customer into a captive even when technically still free to leave.
