AetherIdentity: A Falsification-First Investigation of Decentralized Agent Identity in the Aether Family

AetherIdentity is a candidate eighth functional dimension of the Aether family. It investigates whether identity proof, continuity, reputation, Sybil resistance, and delegation in multi-agent software ecosystems constitute a genuine gap not already covered by the seven existing dimensions. The method is falsification-first: five failure conditions (F1–F5) and six requirements (R1–R6) are stated before the candidate is described. The paper specifies a five-layer architecture hypothesis (identity, continuity, reputation, Sybil resistance, delegation), restates two propositions as proof sketches, and assesses the candidate by argument. No implementation, test, or experiment is reported. F1–F4 are not falsified by argument, each with a stated reservation; F5 is untested. AetherIdentity is a candidate, not a result.
