reactor orchestrate runner not executing, no errors

I have been setting up the reactor states in our salt environment for the first time.
The local.state.single reactor states working. However, there is a need to use runner.state.orchestrate.

After reading all the past issues and examples I have found for the numerous variations of reactor state syntax specifically around passing pillar to the underlying orchestrate state, I have one config that at least isn't throwing errors in the master log.
I know the event is firing from a minion and it's being detected as the reactor state executes. However, the orchestrate state that IT is supposed to execute isn't firing. I assume it's not because the change doesn't take place and there's nothing in the master log.

Reactor config in master

reactor:
    - 'orch/group/role/do_the_thing':
    - salt://reactor/orch/common/role/test_do_the_thing.sls?saltenv=test

Reactor state

test_do_the_thing_reactor:
  runner.state.orchestrate:
    - mods: orch.common.role.do_the_thing
    - kwarg:
       pillar:
         minion: {{ data['data']['minion'] }}, 
         role: {{ data['data']['role'] }}, 
         action: {{ data['data']['action'] }}

I fire the event from a minion with this (for reference, this works fine)

orch/group/role/do_the_thing:
  event.send:
    - data:
         role: "myrole"
         minion: {{grains['other-minions']|join(',')}}
         action: "some cmdline action"

Start by reproducing the master reactor configuration and the minion event shown in the issue, then trace the runner.state.orchestrate entry point and its pillar handoff. Compare the event detection with whether orch.common.role.do_the_thing is invoked; done means the orchestrate state executes and produces observable master output.
