x07-concurrency

X07 concurrency is deterministic and virtual (no OS threads); blocking points are explicit.

Canonical patterns

• Use defasync + task.* + chan.bytes.* for deterministic concurrency.
• Avoid implicit sources of nondeterminism (OS clocks, random, network) in solve worlds.
• Keep scheduling decisions explicit and data-driven (inputs → outputs), so runs are replayable.

For the built-in reference guide, use x07c guide and search for defasync / task. / chan.bytes..
