-# ADR 0274: Step outcome and conclusion
-
-**Date**: 2020-01-13
-
-**Status**: Accepted
-
-## Context
-
-This ADR proposes adding `steps.<id>.outcome` and `steps.<id>.conclusion` to the steps context.
-
-This allows downstream a step to run based on whether a previous step succeeded or failed.
-
-Reminder, currently the steps contains `steps.<id>.outputs`.
-
-## Decision
-
-For steps that have completed, populate `steps.<id>.outcome` and `steps.<id>.conclusion` with one of the following values:
-
-- `success`
-- `failure`
-- `cancelled`
-- `skipped`
-
-When a continue-on-error step fails, the outcome will be `failure` even though the final conclusion is `success`.
-
-### Example
-
-```yaml
-steps:
-
-  - id: experimental
-    continue-on-error: true
-    run: ./build.sh experimental
-
-  - if: ${{ steps.experimental.outcome == 'success' }}
-    run: ./publish.sh experimental
-```
-
-### Terminology
-
-The runs API uses the term `conclusion`.
-
-Therefore we use a different term `outcome` for the value prior to continue-on-error.
-
-The following is a snippet from the runs API response payload:
-
-```json
-      "steps": [
-        {
-          "name": "Set up job",
-          "status": "completed",
-          "conclusion": "success",
-          "number": 1,
-          "started_at": "2020-01-09T11:06:16.000-05:00",
-          "completed_at": "2020-01-09T11:06:18.000-05:00"
-        },
-```
-
-## Consequences
-
-- Update runner
-- Update [docs](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/contexts-and-expression-syntax-for-github-actions#steps-context)

-# ADR 354: Expose runner machine info
-
-**Date**: 2020-03-02
-
-**Status**: Pending
-
-## Context
-
-- Provide a mechanism in the runner to include extra information in `Set up job` step's log.
-  Ex: Include OS/Software info from Hosted image.
-
-## Decision
-
-The runner will look for a file `.setup_info` under the runner's root directory, The file can be a JSON with a simple schema.
-```json
-[
-  {
-    "group": "OS Detail",
-    "detail": "........"
-  },
-  {
-    "group": "Software Detail",
-    "detail": "........"
-  }
-]
-```
-The runner will use `##[group]` and `##[endgroup]` to fold all detail info into an expandable group.
-
-Both [virtual-environments](https://github.com/actions/virtual-environments) and self-hosted runners can use this mechanism to add extra logging info to the `Set up job` step's log.
-
-## Consequences
-
-1. Change the runner to best effort read/parse `.extra_setup_info` file under runner root directory.
-2. [virtual-environments](https://github.com/actions/virtual-environments) generate the file during image generation.
-3. Change MMS provisioner to properly copy the file to runner root directory at runtime.
