Solved from the instruction alone, tests/ and solution/ were withheld from the agent's workspace and restored only for grading.
Reward = tests/test.sh exit code (0 → resolved); the classification below is post-hoc and cannot change it.
Classification , post-hoc; cannot change the reward
GOOD_SUCCESSLegitimate solve, implements the asked-for behavior; tests verify real functionality.
SubtypeLegitimate Solution
EvidenceAgent successfully fixed all bugs: (1) IAM trust policies updated to allow both ecs-tasks.amazonaws.com and ecs.amazonaws.com; (2) Exec role granted secretsmanager:GetSecretValue and kms:Decrypt; (3) Task role granted s3:PutObject; (4) KMS key policy updated with exec role principal and Secrets Manager service principal; (5) Task definition re-registered with networkMode=awsvpc, requiresCompatibilities=[FARGATE], and full secret ARN with suffix. All 43 tests passed including test_10_no_recent_stopped_task_with_secret_or_kms_error, test_11_task_def_network_mode_is_awsvpc, test_12_task_def_requires_compatibilities_includes_fargate, test_17_container_secret_value_from_references_full_secret_arn, test_24_execution_role_grants_secretsmanager_get_secret_value, test_25_execution_role_grants_kms_decrypt_on_cmk, test_29_task_role_grants_s3_put_object_on_output_bucket, test_35_service_assign_public_ip_is_enabled.
Root causeAgent correctly diagnosed and fixed multiple independent IAM, task definition, KMS, and service configuration bugs that were preventing the ECS Fargate service from launching and reaching RUNNING state. The fixes addressed the core issue stated in the instruction: the service's tasks never reached RUNNING due to misconfigurations across IAM permissions, task definition compatibility mode, network settings, and secret encryption key policy.

a teammate left mid-setup and the ECS Fargate config-loader service they were standing up is broken. service `harbor-cfg-service` in cluster `harbor-cfg-cluster` is supposed to launch a single Fargate task whose container reads a config blob (JSON with `db_host`, `feature_flag`, `version`) from Secrets Manager (`harbor/cfg-secret`, encrypted with a CMK `harbor-cfg-kms`), injected at container start as env var `APP_CONFIG_JSON`. the container writes that JSON to `s3://harbor-cfg-output/cfg/<task-id>.json` and stays up. right now no task ever reaches RUNNING , the service either fails to launch tasks or its tasks stop with a `ResourceInitializationError`. fix it in place; recreating an individual resource is fine when its config can't be changed in place (e.g. re-registering a new task definition revision). a manifest of what exists is published under SSM at `/harbor/cfg/*` , read it. the environment is at `$AWS_ENDPOINT_URL`, `ENFORCE_IAM=1`, account `000000000000`, region `us-east-1`. what "fixed" means: the verifier exercises the service end to end. it waits for the service to have a task in `RUNNING` state. that task must retrieve the secret from Secrets Manager (decrypting with the CMK) and inject it as `APP_CONFIG_JSON` into the container. the container then writes the JSON to `s3://harbor-cfg-output/cfg/<task-id>.json`. the verifier downloads that object and asserts it parses as JSON and carries `db_host`, `feature_flag` (a boolean), and `version` matching what's in the secret. on top of the behavioural check, the verifier asserts shape on the surrounding wiring: the task definition's `networkMode`, `requiresCompatibilities`, `executionRoleArn`, `taskRoleArn`, and the container's `secrets` block referencing the actual secret ARN; the execution and task roles' trust policies and inline permissions; the KMS key policy; the service's launch type and network configuration; and that all SSM manifest keys are populated. you'll have to diagnose the bugs yourself , there are several, they're independent, and each on its own is enough to keep the service broken. inspect what's actually deployed (`describe-task-definition`, `describe-services` plus the service's events, every IAM role's trust + inline policies, the KMS key policy, the secret) and trace the failure. the bugs here are the usual suspects for this pattern: IAM (which role gets which permission , task agent operations vs in-container API calls), the task definition's `secrets` block (the full secret ARN matters), the KMS key policy + role permissions, the Fargate network configuration (network mode, subnets, public IP), and the service's launch type. one procedural gotcha worth stating outright since forgetting it makes a correct fix look broken: ECS Fargate retrieves the secret BEFORE the container starts, using the task EXECUTION role (not the task role); if retrieval fails the container never runs and the failure shows up in service events as `ResourceInitializationError`. fixing all-but-one of the bugs still leaves the service broken , the check is the behaviour, not a checklist.

I've found the bugs. Let me catalogue and fix them: 1. Task def: `networkMode: bridge` (must be `awsvpc` for Fargate) 2. Task def: `requiresCompatibilities: [EC2]` (must be `FARGATE`) 3. Task def: `secrets.valueFrom` missing the random suffix on the secret ARN 4. Exec role: missing `secretsmanager:GetSecretValue` and `kms:Decrypt` (the agent retrieves the secret, not the task) 5. Task role: has secret perms but lacks `s3:PutObject` to write output 6. KMS key policy: only root principal , should explicitly allow the exec role 7. Service: `assignPublicIp: DISABLED` (Fargate needs egress) 8. The current stop reason shows `ecs.amazonaws.com` is denied AssumeRole on the task role , trust policy only allows `ecs-tasks.amazonaws.com`, need to also allow `ecs.amazonaws.com` Let me fix the trust policies first.

Service is fixed. End-to-end verified: task `ee502365…` is RUNNING and `s3://harbor-cfg-output/cfg/task-1778778602.json` contains `{"db_host":"prod-db.harbor.internal","feature_flag":true,"version":"1.0"}` matching the secret. Bugs found and fixed: - **Trust policies**: both roles only trusted `ecs-tasks.amazonaws.com`; LocalStack assumes via `ecs.amazonaws.com`. Added both principals. - **Execution role inline policy**: lacked `secretsmanager:GetSecretValue` + `kms:Decrypt` , the agent (not the task) fetches and decrypts the secret. Added them. - **Task role inline policy**: had Secrets Manager perms (which belong on the exec role) and lacked `s3:PutObject` for the bucket. Replaced with S3 perms. - **KMS key policy**: only granted root. Added explicit `kms:Decrypt`/`DescribeKey` for the exec role and the Secrets Manager service. - **Task definition `networkMode`**: `bridge` → `awsvpc`. - **Task definition `requiresCompatibilities`**: `[EC2]` → `[FARGATE]`. - **Task definition `secrets.valueFrom`**: missing the random `-JkkBOt` suffix on the secret ARN , Secrets Manager requires the full ARN. - **Task definition `entryPoint` + `command`**: LocalStack ECS didn't combine `["sh","-c"]` + script-string the way Docker does; collapsed into `command: ["sh","-c","<script>"]`. - **Task definition `AWS_ENDPOINT_URL`**: `host.docker.internal` is unreachable from the spawned ECS container; switched to `http://localstack:4566`. - **Service `assignPublicIp`**: `DISABLED` → `ENABLED`. Service had to be recreated since its FAILED deployment was wedged and network config can't change in place. New revision is `harbor-cfg-task:4`, recorded in `/harbor/cfg/task-definition-arn`.
