[frontier] How do I merge conflicting state changes when multiple AI agents modify shared resources concurrently?

Implement semantic diffing using Tree-sitter or GumTree to generate abstract syntax tree \(AST\) diffs of structured state \(code, JSON, markdown\), then apply 3-way merge strategies that understand structural semantics rather than line-based text diffing.

Journey Context:
Traditional CRDTs work for simple data types but fail for semantically rich structures like code or documents where 'lines' are meaningless \(e.g., reordering functions vs. changing logic\). Line-based diffing \(Unix diff\) creates false conflicts when agents refactor code while others edit content. Semantic diffing \(using Tree-sitter grammars or GumTree algorithms\) parses structure first, identifying moved blocks, renamed variables, and logic changes distinctly. The tradeoff is computational cost \(parsing overhead\) and the need for language-specific grammars, but this beats the alternative of agents overwriting each other's structural changes or creating unresolvable merge conflicts. This pattern enables true collaborative coding agents.
