Why: Tool calls stayed invisible until execution finished, and turn, tool, timeout, and output caps stopped long tasks early.
Evidence: go test ./internal/runtime/ ./internal/tools/ ./internal/prompts/ ./internal/squadadapter/ ./internal/runmgr/ ./internal/app/ ./internal/settings/
Impact: tool.call.delta and tool.output reach the client; default profile, subagents, and squad no longer cap turns or tool calls; exec timeout defaults to 600s with no hard ceiling. A profile or subagent maxTurns above 0 still applies.

Why: A conversation run has no launch of its own, so a script step looked up an empty copy and refused to run.
Evidence: go test ./internal/runtime/ -run TestRegisteredWorkflowUsesItsOwnScriptCopy passed. The body is taken from the launch passed into the runner.
Impact: Intent-started runs still use the copy made at start.

Why: The planner treated the goal as work to do, and the critic accepted a draft that missed the required line.
Evidence: go test ./internal/runtime/ ./internal/prompts/ passed. The planner task now says to output JSON and not perform the goal.
Impact: A missing required sentence is a failed check. The planner still cannot add script steps.

Why: The critic asked the provider for a model named verify, so every check failed before it could read the step output.
Evidence: go test ./internal/runtime/ -run TestJudgeUsesConfiguredModel passed. The request model is MiniMax-test when that is the configured chat model.
Impact: A missing lightweight route still falls back to the chat model. Unparseable output still counts as a fail.

Why: Plugin scripts and model-written scripts need the same step runner, without giving the script a way to call interpreters or start another workflow.
Evidence: go test ./... passed. Callbacks, denied tools, the 50-call cap, a 1MB line, and cancel-kills-the-process are covered. A model script does not run until the switch is on and the user confirms.
Impact: runtime.workflowScripts stays off by default. Plugin script bodies are copied into the launch. Squad entry still has no run_workflow.

Why: A goal should become steps only after the same limits as a declarative workflow, and only after the user accepts the plan.
Evidence: go test ./internal/runtime/ ./internal/prompts/ passed. Over-limit and script steps are rejected before confirmation. A no choice does not execute.
Impact: The planner profile is agent.sub.workflow-plan. run_workflow stays off subagent tool lists.

Why: A matched intent needs to run the copied definition, ask for missing slots, and stop when a step or the whole workflow exceeds its retry cap.
Evidence: go test ./internal/runtime/ ./internal/runmgr/ ./internal/server/ ./internal/prompts/ passed. The five step kinds update the plan, an unparseable critic counts as a failure, and run_workflow by id runs the registered definition.
Impact: Squad entry does not declare run_workflow. Script steps still return an error until the script host lands. Goal and script arguments are rejected for now.

Why: A hit intent should start the bound workflow, and a command that shares the same id still has to win.
Evidence: go test ./internal/intentgate/ ./internal/runmgr/ ./internal/server/ passed. Recognize keeps slots and the missing-slot question. StartWorkflowRun copies the definition and selects the workflow runner even when mock is on.
Impact: Ordinary turns are unchanged. The workflow runner body is still a stub until the executor lands.
