The task name has multiple critical issues:

1. Pipeline Breakage: The task family name has changed from ${var.environment_name}_forms-admin_mailchimp_sync (e.g., production_forms-admin_mailchimp_sync) to forms-admin-mailchimp-sync. This breaks the deployment pipeline (deploy-forms-admin-container.tf lines 241 and 270) which expects the old naming pattern with underscores and environment prefix. The pipeline's update task definition steps will fail to find the correct tasks.

2. Logging Issues: The task name is used as the CloudWatch log stream prefix (see ecs-scheduled-task/main.tf line 30). Without the environment name, logs from all environments will have the same prefix (forms-admin-mailchimp-sync/main/*), making it impossible to filter by environment. The old code used forms-admin-${var.env_name}-organisations-sync which included the environment. The troubleshooting documentation in orgs-sync.tf line 43 expects environment-specific log streams.

The task_name should be ${var.env_name}_forms-admin-${replace(each.key, "_", "-")} to match the old pattern and preserve both pipeline compatibility and environment-specific logging.

The moved blocks assume that the old resources existed (i.e., the features were enabled with count=1), but in environments where enable_organisations_sync or enable_mailchimp_sync were false, these resources never existed. When applying this change to those environments, Terraform will try to move non-existent resources and then create new ones, which should work but may cause state inconsistencies. Additionally, since the new module creates resources unconditionally, this means features that were previously disabled will suddenly become enabled in environments like staging and user-research.

The description says "The scheduled task name suffix" but this variable is actually used as the complete task family name, not just a suffix. Looking at the usage in main.tf line 5 and line 18 in scheduled-tasks.tf where it's set to "forms-admin-${replace(each.key, "_", "-")}", it's clear this is the full name. The description should be updated to "The complete task family name for the scheduled task" or similar to accurately reflect its usage.

The monitoring resources for orgs sync failures have lost their conditional creation. Previously, these resources had count = var.enable_organisations_sync ? 1 : 0 which prevented them from being created when organisations sync was disabled. Now these resources are always created, which means EventBridge will be monitoring for a task that may not exist in environments where enable_organisations_sync is false. This will create unnecessary resources and potentially confusing monitoring alerts.

Similar to the organisations sync monitoring, the mailchimp sync failure monitoring resources have lost their conditional creation. Previously, these had count = var.enable_mailchimp_sync ? 1 : 0. Now they're always created even when mailchimp sync is disabled in the environment, leading to monitoring of non-existent tasks and unnecessary resource creation.

The scheduled tasks are now created unconditionally, but the variables enable_organisations_sync and enable_mailchimp_sync still exist and are being passed to this module. The old implementation used these variables with count to conditionally create the resources. This change means that both scheduled tasks will always be created in all environments, regardless of the variable values, which could lead to unintended task executions in environments where these syncs should be disabled (e.g., staging and user-research environments have both set to false in their tfvars).
