`POST /api/workspaces/{workspaceId}/automation-templates/{templateId}/install/preview`

Read-only validation of saved dependencies and destination field conflicts. Schema v3 also returns bindings[] (slots plus destination options), unresolvedBindingIds, and canInstall which requires every required slot to be decided. Legacy v1/v2 snapshots keep the prior blocker behavior. Grouped issues include context.locations.

## Authentication

Requires one of the following:

- `BearerAuth`, http, header `Authorization`, format `JWT`
- `ApiKeyAuth`, apiKey, in header, header `X-API-Key`, format `API_KEY`

## Path parameters

- `workspaceId` (`post/api/workspaces/workspaceId/automation-templates/templateId/install/preview.path.workspaceId`; string, required)
- `templateId` (`post/api/workspaces/workspaceId/automation-templates/templateId/install/preview.path.templateId`; string, required)
  - format `uuid`

## Request body

_Required._

- `destinationWorkspaceId` (`post/api/workspaces/workspaceId/automation-templates/templateId/install/preview.destinationWorkspaceId`; string, required)
- `bindings` (`post/api/workspaces/workspaceId/automation-templates/templateId/install/preview.bindings`; map<object>, optional) — Schema v3 slot decisions keyed by binding id (seq:, flow:, field:, field-conflict:).

## Example request

```json
{
  "destinationWorkspaceId": "string",
  "bindings": {
    "property1": {
      "action": "bind",
