stream: Archon and the machine underneath

One workstream: the defects of the workflow runner and of the machine run 3 exposed, none of them about profile-card and all of them reaching every session that dispatches a Box. Sub-issues are the tickets; this ticket carries no state and no priority by the stream rule in docs/agents/labels.md.

Source: findings register on develop at bcf688a, § "G. What run 3 taught about the instrument" (rows G1, G2, G3, G10, G11). The three "upstream: Archon" tickets are filed here as the record; whether they go to Archon's own tracker is the maintainer's call, as with Archon 0.9.0 adoption.

Mirrors on the Consumer's board: Task 43100 (the five documentation rows under 43039), Task 43102 (the Node pin under 43039), Task 43101 (a control beside each check under 43037).

Start with the findings register on develop at bcf688a, section “G. What run 3 taught about the instrument,” and read docs/agents/labels.md for the stream rule. Follow the G1, G2, G3, G10, and G11 sub-issues and compare the Consumer-board mirrors; this stream is complete only when those individual tickets define and resolve the reported defects.
