Status: IN
The codebase systematically derives new capabilities from existing data and structures rather than introducing new mechanisms: identifiers from existing pairs and messages (eliminating coordination), data structures from sign-flipped heaps and repurposed topics (inheriting proven properties) — favoring derivation over creation at both the data and infrastructure levels.
Both d2 nodes show the same philosophy at different levels — identity derivation avoids creating new coordination, structural adaptation avoids creating new abstractions — the shared principle is that derivation is preferred over creation
Depends on (SL): identity-derivation-trades-validation-for-simplicity, adaptation-over-invention
