Institutional evolution
Adaptive constitutional change.
A research proposal testing how changes to shared rules and concepts affect commitments, continuity and recovery in multi-agent systems.
Research proposal
This programme proposes treating institutional change as an explicit migration. A change to rules, shared concepts or authority is examined for its effects on existing commitments before adoption.
This brief sets out a question and proposed method. It does not report experimental findings. Etylon project · Updated 20 October 2026.
Versioned rules and explicit amendment dependencies should help institutions adapt while retaining intelligible commitments. The limits and costs of reversal must be tested.

Research setting
The institution changes while its obligations remain live.
Amendments are evaluated not in isolation, but through the commitments, delegated powers and shared meanings they can disturb.
Proposed research protocol
Model the cascade before migrating the institution.
- 01Encode
Represent the active rule, ontology and authority dependencies.
- 02Amend
Introduce a bounded change with an explicit institutional rationale.
- 03Simulate
Trace the amendment through commitments and precedents.
- 04Migrate
Apply the change to a reversible institutional scope.
- 05Review
Measure continuity, incompatibility and rollback safety.
A case to examine
A cooperative changes its definition of an urgent workload while compute reservations remain active. The study asks which reservations keep their original terms, who can approve exceptions and how affected teams learn what changed. Restoring the previous definition cannot recover compute already consumed.
What to compare
Compare an explicit migration procedure with direct rule replacement under equivalent changes and active commitments. Vary the number and depth of affected dependencies. Include conflicting interpretations, partially completed actions and a failed amendment so that continuity is tested under pressure. Study how a useful convention can become an explicit institutional rule. Compare adoption procedures that preserve existing commitments with changes inferred from repetition alone.
Conditions and limitations
Specify what continuity means for each commitment and what state can actually be restored. Distinguish rule rollback from compensation for external effects. Retain both the old and new terms and the reasons for the change. A successful reversal in one bounded environment does not imply that every amendment is reversible.
Proposed measures
Define the evidence before judging the result.
- Adaptation time
Time from a proposed amendment to an agreed and usable institutional state.
- Continuity loss
Existing commitments that become unintelligible, unfulfilled or disputed after a change.
- Precedent compatibility
Whether earlier decisions remain interpretable under their original terms.
- Amendment cascade depth
How far one change propagates through dependent rules and commitments.
- Rollback limits
State that can be restored and effects that instead require repair or compensation.
- Coordination recovery
Time and work needed for participants to resume compatible commitments.
Apparently local amendments create unbounded reinterpretation, break earlier commitments or cannot be reversed without erasing the evidence needed to understand what changed.
