How to abort flow when a policy in a stage fails?

Describe your question/
Is it possible to completely abort a flow when a single policy in one of the stages fails?

Relevant info
I have flows with multiple stages and i'm already using deny stages with policies to have some kind of control. each stage is responsible for retrieving or evaluating a specific thing e.g. an invitation flow i'm currently working on:

• invitation accept stage
• prompt stage for pre-enroll: get or create existing user via policy and then prompt enrollment type
  HOWTO: abort flow on error (e.g. necessary attributes missing or user creation problem)
• deny stage: deny if the user is already active
• redirect stage: check set enroll type & redirect to next flow according to enroll type
• deny stage: deny if no enroll type matched

I know that i can add a check in the deny stage after the HOWTO question to deny the user but that means i need to basically add deny stages everywhere and execute similar checks everywhere (e.g. the get or create user code that i need in the prompt stage already did make sure that i have a user or error out).

Is it somehow possible (e.g. programatically; setting next stage or something) to abort the flow execution?

Note:
Every stage and flow binding is already set to 'failure result' 'dont pass' and 'policy engine mode' to 'all'; i also don't want to retry or restart the flow. In a nutshell I think I would like to have a dynamically inserted deny stage?

Version and Deployment (please complete the following information):

• authentik version: 2025.8.4
• Deployment: docker-compose

Start by tracing the flow execution, stage failure handling, and policy evaluation behavior described in the issue. Reproduce the multi-stage invitation flow with a failing policy and verify whether execution can stop without retrying or restarting. Done should be a documented, tested way to abort dynamically, or a clear explanation of the supported alternative.
