This record introduces the Engagement Credit Economy (ECE), a post-labour participation architecture designed to render necessary but non-market contribution visible, remunerated, and legitimate without coercion, labour substitution, or exploitation. As optimisation and automation weaken the historical coupling between labour, income, and social legitimacy, existing policy instruments increasingly misclassify contribution, care, and disengagement. ECE addresses this structural failure by providing a bounded accounting framework for participation that markets no longer price but societies continue to require. The dossier currently comprises two core papers: The Engagement Credit Economy (ECE): A Post-Labour Participation Architecture, which sets out the core participation, remuneration, anti-exploitation, and exit-preserving design of the ECE framework. The Human Value and Meaning System (HVES): Protecting Dignity in Post-Labour Societies, which defines a non-market boundary layer ensuring that human dignity, meaning, and moral standing remain unconditional and are not rendered contingent on participation, productivity, or optimisation. Together, these papers establish a layered civic architecture in which participation recognition (ECE) operates alongside protected human value (HVES), with strict non-convertibility between the two. This record serves as the architectural anchor for the broader Engagement Credit Economy dossier. Additional papers extending the framework into governance, evaluation, community initiatives, AI-assisted coordination, and sector-specific applications will be linked to this record as they become available.
