Every contingency left a fingerprint: a compact event log designed for later review. The logs were human-readable, layered into the binary as a compressed appendix. You could boot a monitor, read the narrative, and know whether a decision had been conservative, experimental, or altruistic — in the sense that it favored mission survival over raw performance. Porting Sonic Bumper to a cube-sat and to a ground rover revealed its true power. On the cube-sat, energy constraints forced the Engine into a frugal mode. It learned to use micro-impulses and to let attitude drift within noncritical windows. On the rover, it emphasized compliance and obstacle negotiation, using bumper algorithms to interpret contact as information rather than catastrophe. The same core, different masks.
