The City & The City

Source: Wikipedia Topic: Multiple valid views over one substrate with carefully governed crossings.

Core idea

The City & The City is useful as a metaphor for multiple simultaneous realities rendered over one shared substrate, with boundary crossings treated as first-class events.

Harness takeaway

A studio can use multiple synchronized view_definitions over one log, while treating cross-view leakage or bridge actions as auditable transitions rather than invisible magic.
