CompositeLoom
A Loom that weaves one logical session from several constituent Looms ("plies"). The union of plies covers the session's peer set; the list order is a send-preference hint (most-preferred first).
The ply set may change while the session is live: construct with a StateFlow of the desired set and push a new list to attach or detach plies. Each emission is reconciled against the current live set — new entries are woven in, removed entries are detached. The list constructor is the degenerate case of a never-changing flow.
Parameters
The desired ply set; emit a new value to reconcile (attach/detach).
Forwarded to each CompositeSeam as the scope for its internal coroutines (scheduling only — the woven seam's thread-safety is via a lock + atomics, so it is correct under a multi-threaded dispatcher). Production default (Dispatchers.Default); tests inject a dispatcher derived from the test scheduler.
Constructors
Static convenience: a fixed ply set that never changes after weave().
Functions
Whether this fabric can be attempted now. Default FabricAvailability.Available; fabrics gated on a runtime capability override.
Establish a Seam according to rendezvous — either host a new session or join an existing one.
