jschoubben 858b06a94e Take mesh-sdk at c8e3509, which counts an item's text as a placement of a config value (issue 1658)
mesh/repo-check head 858b06a94e69 merged into trunk 12752911b644 — fail: head 858b06a94e69 does not merge cleanly into trunk 12752911b644: in conflict go.m…
mesh/delivery-group group fix/1656-xterm-config rejected: a member's own check failed
mesh/merge-gate group fix/1656-xterm-config: composed again for the group's new heads
mesh/delivery superseded: a newer head of the same pull request
