mesh/delivery-group group fix/340-replay rejected: a member's own check failed
mesh/merge-gate out of date: judged against trunk eb7ee921b533, the trunk is now 49102e1645c9; judged again on a recheck or when it is merged
mesh/repo-check out of date: judged against trunk eb7ee921b533, the trunk is now 49102e1645c9; judged again on a recheck or when it is merged
mesh/delivery superseded: a newer head of the same pull request
The settings verb took the agent module's managed settings and an empty runtime configuration's url from any caller. The replay uses only what the controller had before #172, so mesh-lab's prover can show it fails there.

// Replay of novox/hq issue 340 (2026-10-09): the agent's module keeps the managed settings and tool servers every
|
|
// Claude Code session on a node obeys in a mergeable file, and the settings verb took any key for it from any
|
|
// caller of the mesh's verbs, so an agent could give every person's session a hook of its own. The same held for
|
|
// every mergeable file: an identity provider's runtime configuration that starts empty took a `url` of the
|
|
// caller's, where its provisioner would send the admin login. Written only with what the controller had before its
|
|
// fix (mesh-controller #172): a mesh, a registered manifest, an assignment, the settings verb run as a verb runs
|
|
// it and as the terminal runs it, and the layer the inventory keeps — so it is laid over the commit before.
