The current one is 4000+ lines of JSON. That makes it intimidating/challenging to edit, review, etc.

I think the strawman is a layout like

├── components
│   ├── parameters
│   ├── responses
│   ├── schemas
│   └── securitySchemes
├── paths
├── spec_refs.json
└── spec_bundled.json

and we use $refs to link between them. e.g. The paths section of the spec file would paths/* look like

"paths": {
    ...snip
    "/package_policies": {
      "$ref": "paths/package_policies.json"
    },
    "/package_policies/{packagePolicyId}": {
      "$ref": "paths/package_policies/{packagePolicyId}.json"
    },
    "/fleet/setup": {
      "$ref": "paths/fleet/setup.json"
    },
    "/epm/packages/{pkgkey}": {
      "$ref": "paths/epm/packages/{pkgkey}.json"
    },
    ...snip
  },
And a file at `paths/package_policies/{packagePolicyId}/post.json` like
{
  "operationId": "post-agent-policy",
  "summary": "Agent policy - Create",
  "parameters": [
    {
      "$ref": "../components/parameters/xsrfHeader.json"
    }
  ],
  "requestBody": {
    "content": {
      "application/json": {
        "schema": {
          "$ref": "../components/schemas/NewAgentPolicy.json"
        }
      }
    }
  },
  "responses": {
    "200": {
      "description": "OK",
      "content": {
        "application/json": {
          "schema": {
            "type": "object",
            "properties": {
              "item": {
                "$ref": "../components/schemas/AgentPolicy.json"
              }
            }
          }
        }
      }
    }
  }
}

Everything will remain OpenAPI & JSON for now. There will be a separate ticket & pass for switching some parts to JSON schema so we can use them in more places (e.g. the route validators like #76546)

We'll also retain single bundled one e.g. spec_bundled.json above (and hopefully a simple yarn or npx command to create it) any tools which don't deal with the multi-file setup

## Summary

replaces #77378 
fixes #77290

 * Replace the 4000+ line `spec_oas3.json` file with one ~75 line overview file `entrypoint.yaml` which imports the various pieces from other directories.
 * Switched from JSON to YAML for "source" files because they're less noisy & more human-friendly. `package-registry` & `package-spec` both define specs in YAML as well. We can always convert them to JS for any library that needs it.



## Dev docs
### New structure

```
openapi/
├── README.md
├── bundled.json
├── bundled.yaml
├── components/
├── entrypoint.yaml
└── paths/
```

There are `README.md` files in `openapi`, `openapi/components`, & `openapi/paths` with information about the purpose, conventions, decisions, etc for that directory

* `entrypoint.yaml` is the overview file which links to the various files on disk.
* `bundled.{yaml,json}` is the resolved output of that entry & other files in a single file.

    ```
    nvm use 12;

    npx @redocly/openapi-cli bundle entrypoint.yaml -o bundled.yaml
    ```

    npx swagger-cli bundle -o bundled.json -t json entrypoint.yaml
    npx swagger-cli bundle -o bundled.yaml -t yaml entrypoint.yaml
    ```
    </details>

 * [Paths](paths/README.md): Started with a flat `paths` directory with each path in a separate file. We can move on to a nested file-per-operation like #77378 or any other approach later
