Payload Delivery and Microdrop-Mediated Self-Healing in AMW Repair

Adaptive Matrix Worm (AMW) payload delivery is best understood as a hierarchical operation in which microdrop- class coagulant payloads are the primary self-healing mechanism, anchor-class adhesives are the structural-repair mechanism, and passive elongation-and-equilibrium dynamics of the host NRL matrix are the supporting passive-healing substrate. Earlier framings of this canonical treated microdrops as one option in a flat payload taxonomy and did not develop the matrix's own response to damage; the v0. 3 revision foregrounds microdrops as the modal self-healing payload class and adds passive matrix dynamics as a supporting mechanism, producing a coupled active-passive repair architecture in which the AMW delivers active payloads to a deforming, water-filled NRL matrix where passive void contraction and microdrop coagulation jointly determine repair success. The v0. 2 placement-budget framework (placement error = navigation error deposition error) and the unified compliance metric E* are preserved without modification: the placement-budget specifies when the AMW can deliver payloads to the target, and E* specifies when the payload-AMW-passage-substrate four-way mechanical compatibility holds. E* is defined exactly once in this canonical (§) and is cited textually from siblings II. 4, II. 5, and II. 6 per the AMW arc's cross-paper consistency convention. Microdrop chemistry is treated at coagulant-behavior level: void filling, flow slowing, droplet aggregation, and progressive sealing, grounded in the published fibrin / coagulation literature and the seminal autonomic-healing-of-polymer-composites work. Passive elongation closure is treated cautiously, with the defensible claim that high elongation capacity makes passive void contraction plausible under appropriate geometry and pressure conditions; the stronger claim that the structure self-heals passively is named as out of scope for v0. 3. Bench Loop H, the Payload Delivery Cell, is the bench-scale instrument that exercises microdrop deployment, placement-budget verification, and E* characterisation with explicit a priori falsification criteria. The central engineering claim: when payload delivery, matrix compliance, passive deformation, and microdrop coagulation align, repair succeeds; when they do not, the failure mode is identifiable from the placement-budget and E* framework, and the recoverability doctrine of II. 6 routes the response.
