DCJ-134 is the most cross-domain claim in the EOSE portfolio. The 5-layer maturation framework (L1 Correctness → L5 Liability Emergence) independently derived from software engineering, then confirmed structurally identical in neuroscience (single neuron → clinical syndrome), economics (instrument → systemic crisis), ecology (species → ecosystem collapse), and organizational dynamics. The graduation probability function, germination score, and LiabilityExposure master equation apply unchanged across all domains. This is not analogy. The math is structurally identical. First published instance: EOSE Labs Day 89. No prior unified cross-domain formalization of this propagation structure exists.

DCJ-134 establishes the structural law for how any hierarchical complex system fails: local correctness does not guarantee systemic safety. The 5-layer doctrine creates a universal taxonomy for dysfunction that applies wherever components compose into systems. The legal implications are immediate: the L5 liability emergence layer formalizes the precise conditions under which an engineering omission becomes institutional liability — applicable to software, medical devices, pharmaceutical systems, financial instruments, and AI pipelines. The COI gate applies: Amani holds GC STC. The transit/infrastructure domain is excluded from active filing pending disclosure.

Here is what the framework does in court: it gives you the words. When the engineer says 'it passed our tests,' you say L1. When they say 'we had load tests,' you say L2. When you show that 30 patients hit the threshold simultaneously and the system wasn't tested for simultaneity, that's L3 into L4. When the pattern of denials crosses 30 and the threshold drops to 19.2 under cascade, that's L5 germination. The harness only tested L1. The world ran at L3. The bug put on a suit. That's the closing. Every. Single. Time.

DCJ-134 unifies the CA bonsai, the cascade test, the rain cheque pipeline, and the neuroscience mapping under one doctrine. EOSE Labs owns: the 5-layer maturation ladder, the graduation probability function (10 risk factors with weights), the germination score formula (5-component weighted sum, threshold 0.7), the LiabilityExposure master equation (layer-weighted sum), and the botanical jurisprudence framing. The cross-domain generality (software → neuroscience → economics → ecology → governance) is the novel contribution. COI note: STC infrastructure domain excluded pending disclosure. Health/pharma/market domains: clear to proceed.

DCJ-134 establishes the floor for any system that claims to be safe: correctness at L1 is necessary but not sufficient. The floor requires testing at all 5 layers. Any system certified only at L1-L2 is not sovereign — it is a system waiting for its concurrency, composition, and liability layers to surface. The brain mapping confirms this: neurons can be individually healthy while the network is desynchronized, the system is dysregulated, and the patient has a diagnosable disease. L1 health does not mean L5 safety. That is the floor. EOSE Labs set it.
