Bead opened 2026-06-20 via `start-bead message-channel`, hatched mid-conversation from the parent bead `0a0d4bbc` (netlogo-user-conference-2026).
## Pre-bead context This bead was spawned by one line inside the parent bead's self/myself discussion. The relevant parent turn (verbatim), which is the seed: > it's an inside nod to the difference of self and myself in netlogo syntax. it's also a hey-you-its-me. it's also raising the ASK having the caller reference which is an important message-channel. start-bead message-channel for ask but also browser standard of message-channel (1:1) and named broadcast channels The full self/myself reading lives in the parent bead at [`0a0d4bbc/.../02-self-and-myself.md`](https://redfish.acequia.io/guerin/.agents/0a0d4bbc-5310-486b-97af-0e16646347a4/2026-06-20/notes/02-self-and-myself.md).
## Turn 1 — Assistant (bead open) Scaffolded the bead (about.md, uploads/README.md, this chat log, orientation note). Recorded the thesis in [`notes/00-message-channel-orientation.md`](https://redfish.acequia.io/guerin/.agents/a7f3d043-d107-4cd0-9c76-c44502f99f23/2026-06-20/notes/00-message-channel-orientation.md): the message-channel as the edge along which agents coordinate, whose essential payload is the **caller reference** (`myself`). Three faces of one primitive — NetLogo `ask`/`self`/`myself` (caller reference, in-model), browser **MessageChannel** (1:1 transferable `MessagePort` pair, in-page), browser **BroadcastChannel** (named many-to-many, same-origin). Mapped them onto acequia's "hey you, it's me" dock protocol, bead-remote `request/`→`response/`, acequia-link corridors, and distributed-MVC view-as-controller. Connected to the ROP (projection as a function of `myself`). Left 5 open questions for Stephen (naming, MessageChannel⇄dock bridge, BroadcastChannel⇄named-docks, transferability vs chain-tokens, channel apoptosis).
