Three moats

Future orchestration in Pytxo routes through three layers — not around them.

Moat	Codename	Function
Context arbitrage	Signal Core	Scaffold file context so agents spend tokens on work, not noise
Copy-on-write sandbox	Blast Shield	Isolate writes until explicit approval
Concurrency guard	Race Shield	Lock-free registry + stdin buffering across swarms

Implementation status varies by crate — see the repo layout and crate READMEs for what ships today vs planned.

Each moat has a dedicated concept page with behavior details and configuration knobs.
