Module lanes 

Named lane modules.

This is the discoverability-first module tree for applications.

• routing: fanout/work-queue routing via a single router-as-writer loop.
• sequencer: staged flows via sequencer + gating sequences.
• journal: replayable streams via journal (append + tail).

Note: overload/credit-based control is a router policy layered on routing, not a separate region type.

Modules

journal

Journal lane helpers (open + tail utilities).

routing

Routing lane helpers (fanout regions + router loop runners).

sequencer

Sequencer lane helpers (regions + wait strategies).
