Technical Reversibility

Glossary entry in Ethotechnic capabilities (what systems must be able to do). Definitions, checks, and evidence for Technical Reversibility.

Quick takeaways

The first level of the reversibility ladder: the mechanism exists and works.

Definition

The first level of the reversibility ladder: the mechanism exists and works. The switch throws, the rollback completes, the state restores, and a test proves it on the version of the system currently running.

It matters as a floor rather than a finding. Technical reversibility is the cheapest of the three levels to claim and the least informative, because a working switch says nothing about whether operational reversibility or institutional reversibility would survive it being thrown.

Scale: Organizational · Phases: Design, Deployment · Measurability: Fully measurable · Maturity: Core concept

Scope
C. Ethotechnic capabilities (what systems must be able to do). Design requirements that keep people safe when systems scale.
Genealogy
The first rung of the Law VI ladder, kept separate so a passing technical test cannot be reported as reversibility.

Changelog

  • v1.7.0 · 2026-09-18 — Added Non-Finality, Consequential Contradiction, and The Excluded Case, and generalized the falsified denominator into the falsified ledger — completing the five concerns and the fallibilist ground they stand on.
  • v1.6.0 · 2026-09-18 — Added Human Non-Substitutability, Safe Incompleteness, Anti-Conversion Rights, Abstention, Constitutional Debt, Discretion Migration, and Corrigibility Rent — the person-side principles, the three abstentions, and the rent concept.
  • v1.5.0 · 2026-09-18 — Added Exception Absorption, Exception Learning, Case Corrigibility, Structural Corrigibility, Institutional Learning, Corrective Debt, and the Workaround Presumption, formalizing the historical turn: reading institutions through their failure trajectories rather than their stated controls.
