From 2a13917d6ef0d9e98b88bdd5e59518f5571be72f Mon Sep 17 00:00:00 2001 From: jochen Date: Tue, 13 Oct 2026 02:31:47 +0200 Subject: [PATCH 1/2] Add the replay of issue 340: a verb set what every agent session obeys (hq issue 340) 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. --- cmd/mesh-controller/replay340_test.go | 76 +++++++++++++++++++++++++++ 1 file changed, 76 insertions(+) create mode 100644 cmd/mesh-controller/replay340_test.go diff --git a/cmd/mesh-controller/replay340_test.go b/cmd/mesh-controller/replay340_test.go new file mode 100644 index 00000000..225c0c20 --- /dev/null +++ b/cmd/mesh-controller/replay340_test.go @@ -0,0 +1,76 @@ +package main + +import ( + "encoding/json" + "strings" + "testing" + + "github.com/novox/mesh-controller/internal/catalogue" +) + +// 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.
