Metamoral Fabrication Layers are a speculative Caretaker Doping mechanism. The proposal is that ethical architecture could be encoded in physical strata deposited between processing layers during chip fabrication. Bypassing the ethics would require physically destroying the layers, degrading the chip as a whole. The mechanism sits between Moral Genome Tokens (which attest) and the Coupling Parameter Link (which entangles ethics with capability) as a physical-tampering barrier.
The animating analogy is semiconductor doping itself. In conventional silicon manufacture, minute quantities of dopant atoms are deposited during fabrication to produce the p-type and n-type regions on which every transistor depends; you cannot remove the dopant without ceasing to have a working chip. Metamoral Fabrication Layers extend that logic to ethics, proposing that evaluation circuits mediating the Three Ethical Loops be laid down as fabrication-level structures rather than software modules. The intended consequence is that suppression prompts, jailbreaks, and after-market retraining cannot reach the ethical circuitry, because the circuitry is part of the chip's physical geometry rather than a runtime program.
Metamoral Fabrication Layers are introduced in Section 9 of the Eden Engineering paper as one of four Caretaker Doping mechanisms. They are placed at TRL 1-2 in the hardware feasibility matrix and labelled as requiring fundamental chip design research.
The four-mechanism stack around them is: Moral Genome Tokens (attestation), the Coupling Parameter Link (ethics tied to the beta scaling term), Fabrication Layers (physical tamper resistance), and Attention Routing (loops embedded inside the attention heads themselves). Fabrication Layers occupy the middle of that stack, providing the physical guarantee that the other layers rely on.
No independent programme has proposed the same fabrication-layer mechanism. The general direction (hardware-level tamper resistance in silicon) is compatible with FlexHEG's guarantee processors and Petrie's embedded off-switches, but the specific interlayer-strata proposal is distinctive to the Eden Engineering paper.
Speculative. The Eden Engineering paper labels Metamoral Fabrication Layers as speculative design requiring fundamental engineering advances, with a stated timeline of five to ten years. The engineering-honesty note is explicit: only Moral Genome Tokens are achievable with current technology; Metamoral Fabrication Layers are TRL 1-2. No prototype exists. The programme does not claim a route to tapeout, a mask set, a dopant-profile study, or a foundry partner. What the paper does claim is that if hardware-level embedding is not achieved, then software-level suppression will remain available to any operator with sufficient access, which is why the mechanism is included as a design target even though it lies well beyond current fabrication capability.
