Handoff Stream

show ownership or state moving from one person or system to another

Running the actual pattern live via applyPattern() — switch the substrate, stack overlays, watch the signals, or reverse the dynamics. Not a mock.

"Handoff Stream" — show ownership or state moving from one person or system to another. It has a fieldflow layer (solar prominences, aurora, plasma streams, guided matter), a propagate layer (travelling waves through the medium), a link layer (ropes / cloth between neighbours), a memory layer (a decaying trail / hysteresis), and a morph layer (assemble matter into a mark/shape (never words, §11)). Matter follows the field geometry because of fieldflow, not the field-owning force itself. The active render stack is streamlines, field-lines, trails, particles.

Magnetism bends the path between owners and fieldflow carries the object along it — the source cools, the target warms, and a memory trace records the transfer.

Concepts: handoff
Metrics: handoff a semantic lane — drive it with data-field-<metric> (or a domain model); without that its --field-<metric> stays inertcurrent a semantic lane — drive it with data-field-<metric> (or a domain model); without that its --field-<metric> stays inertmemory computed every frame by the platform (proximity · engagement · relationships · age)state a semantic lane — drive it with data-field-<metric> (or a domain model); without that its --field-<metric> stays inert handoff, current, state are host-supplied lanes — drive them with data-field-<metric> (or a domain model); without that, their --field-* stays inert.
Diagnostics: field-lines force-vectors topology

Reduced motion: a transfer timeline with owner badges and a handoff log
Without motion: the transfer reads as a timeline of owner badges plus a handoff log entry, not a flowing animation
