DOI Anchor Infrastructure names the system through which Socioplastics converts an otherwise mutable, platform-distributed corpus into a citable, navigable, and durable epistemic architecture. Its primary function is to provide persistent coordinates: resolvable Digital Object Identifiers, principally through Zenodo and supplemented by Figshare and allied repositories, that remain stable even when blog URLs, platforms, formats, or public interfaces change.

The DOI anchor is not a bibliographic accessory but a load-bearing infrastructural joint, fixing each node, core, or cluster within a wider field of circulation. It operationalises ThresholdClosure by sealing reference without closing interpretation, while also enabling DualAddress, where machine-readable DOI coordinates coexist with human-readable slugs and public routes. At high intensity, DOI anchoring contributes to epistemic autonomy by allowing the corpus to persist beyond any single host; at medium intensity, it organises scalar relations among MasterIndex, VerticalSpine, MetadataSkin, and Legibility Infrastructure; at practical intensity, it grounds citation, archiving, pedagogy, repository indexing, and machinic retrieval. The specific case of core-level and node-level anchors is decisive: operators such as ThresholdClosure, ActivationNode, and soft ontology clusters become findable not as isolated texts but as stable points within a larger GravitationalCorpus. Through Zenodo, Figshare, Hugging Face, GitHub, and cross-referenced public indexes, the Decágono de Autonomía transforms redundancy into resilience. Consequently, DOI Anchor Infrastructure makes Socioplastics teachable, citable, extensible, and machine-augmented at scale: a persistent architecture for knowledge that remains open precisely because its coordinates hold.
