StratigraphicField names the geological condition of knowledge: not a neutral discourse, argumentative territory, or abstract network, but a compressed deposit in which every publication, citation, refusal, marginal note, and failed experiment becomes sediment. Fields acquire authority through accumulation, and their apparent coherence is produced by pressure: canonical texts harden into bedrock, minor annotations remain as loose alluvium, and forgotten theses persist as buried mineral veins. To enter such a field is therefore not merely to acquire terminology, but to sense the weight of prior formations. DiagonalReading responds to this density by refusing both vertical obedience and horizontal superficiality. It cuts obliquely across the archive, moving from central canon to peripheral tag, from contemporary essay to remote footnote, from DOI-stabilised operator to misprision in another discipline. Its aim is not mastery, but angle; it reveals that difference between strata is not archival noise, but structural information. Yet a field composed only of deposits and cuts would either petrify or fragment. PlasticPeripheries names the adaptive edge where exterior pressures can be absorbed without collapse: a hostile review, new method, institutional migration, platform disappearance, or unexpected readership may bend the field, but need not dissolve it. In Socioplastics, this triad clarifies a complete ecology of artistic research. StratigraphicField preserves temporal depth against amnesia; DiagonalReading keeps the archive traversable against monumentality; PlasticPeripheries enable expansion without metastatic excess. The field lives by maintaining weight, angle, and bend: enough sediment to endure, enough incision to think, and enough softness at the edge to grow.
