Stream

A single perspective's bearing on one open question, gathered over time as evidence lands. The per-seat unit of the belief layer, and — the load-bearing contrast with a Thread — the staging ground for a change to canon: a Stream accrues priors and what it settles is folded into the model by a Merge. It reuses the Thread stance machinery (named slots + a Stance of logits / volume / volatility, evolved by evidence), is owned by one member against one perspective, and its belief-log nodes are its priors — the seat's stream of consciousness as it thinks. Many Streams can hold the same question — each a different seat's independently-seeded leaning — forming a local market whose divergence is preserved, never averaged. Opened from a seeding intuition (prior #1), a Stream runs open while the thinking continues, committed when folded into a Merge, and closed once settled.
