Analyst synthesis. The recording establishes that a claim was made. It does not independently establish the claimed effect.
The former registry updated government data frequently until an unannounced API change broke pipelines.
Proposed mechanism: Upstream schema changes disrupt downstream record synchronisation.
Limit: Specific organisational incident; external cause not independently verified.
Broken synchronisation created uncertainty about personal-data accuracy and costly remapping work.
Proposed mechanism: Technical failure changes legal exposure when republishing personal records.
Conditions: Current source alignment and resources to repair it.
Limit: Reported cloud cost and repair duration are not general cost estimates.
The organisation stopped aggregation because recurring cost and legal risk were unsustainable on philanthropic funding.
Proposed mechanism: Unfunded maintenance and compliance risk undermine a useful shared service.
Conditions: Sustainable finance and predictable upstream interfaces.
Limit: Founder account does not prove all registries are unviable.
An audience member asks whose behaviour EITI seeks to change and through what theory of change.
Limit: Requests a causal account beyond data publication.
