10. Software L1/L2 (Two-Layer Architecture) Analogous to crypto L1/L2 (e.g., Ethereum L1 and an L2), the software stack is split into two layers.
The unchanging fundamentals - fixed location, map, consent, safety, and audit - are treated as L1
(immutable). New features and optimizations are implemented as L2 (upgradable). This separation
prevents L2 failures from collapsing the whole network.
L2 may be implemented by large software companies (similar to how Google dominates smartphone
ecosystems). Ideally, users can choose among L2 providers, but network effects may lead to
oligopoly or monopoly. Even in that case, the L1 constitution must prevent deviation.  Figure 10. Immutable L1 core and upgradable L2 extensions (ASCII). L2 cannot override L1; on failure, the system falls back to L1 mode. |
