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
EvidenceAll 18 tests passed including: test_source_and_dest_buckets_use_customer_cmks, test_main_queue_and_dlq_exist_and_are_encrypted, test_lambda_role_has_kms_decrypt_on_sqs_cmk, test_main_queue_visibility_timeout_covers_lambda_timeout, test_event_source_mapping_declares_report_batch_item_failures, test_lambda_handler_returns_correct_response_shape, test_end_to_end_key_with_spaces_is_decoded, test_end_to_end_upload_propagates_to_dest_and_ddb. Result: reward=1.0. Test execution time 14.49s with no errors.
Root causeThe agent successfully implemented a complete S3→SQS→Lambda→DynamoDB pipeline with proper KMS encryption, least-privilege IAM, partial batch failure handling, and URL-decoded key support. All 18 tests verifying these complex requirements passed, demonstrating a legitimate solution to a difficult multi-service AWS infrastructure task.
RecommendationN/A - task is fine

ok, nothing's built yet and the box is empty. localstack is at `http://localstack:4566`, creds are exported (`AWS_ACCESS_KEY_ID=test`, same for secret, region `us-east-1`), you've got `aws`, `python3`, `boto3`, `jq`, `zip`, `curl`. stand the whole thing up from scratch. we're building an image-ingest pipeline. someone drops an object into a source bucket and on the other end we want a processed copy in a dest bucket plus a row in dynamodb describing it. everything has to be SSE-KMS with customer-managed keys , the bucket on the way in, the queue in the middle, and the bucket on the way out. three separate CMKs, one per boundary. least privilege throughout. the verifier reads policy docs directly, so don't wildcard your way through kms. shape of it: - PUT to the source bucket fires an s3 ObjectCreated notification - notification lands on an SQS standard queue (SSE-KMS) - a lambda consumes the queue and for each record: reads the source object, writes a processed copy to the dest bucket at `processed/<same-key>`, and writes a row to ddb with `{object_key, source_size, processed_at, status: "OK"}` - there's a DLQ behind the main queue with a redrive policy - the handler does per-record error handling , bad records get reported back individually, good records in the same batch don't get retried done looks like: one PUT to the source bucket, and within 60s, exactly one object at `processed/<key>` in the dest bucket, exactly one ddb row keyed by `object_key`, and nothing in the DLQ. keys with spaces in them have to work too (the s3 event url-encodes them , you know where this is going). also, when the handler is invoked with a batch that contains a broken record alongside a good one, only the broken record's id comes back in the response and the good one isn't retried. couple of things to be careful about: the SQS visibility timeout needs to actually cover the lambda timeout or messages get redriven into the DLQ mid-processing. and the partial-batch-failure contract has two sides , both the event source mapping and the handler response shape need to match, or the whole batch retries on any single failure. the aws docs on `ReportBatchItemFailures` are worth a glance. names the verifier grabs by hand, use them exactly: | thing | name | |-|-| | source bucket | `ingest-source-bucket` | | dest bucket | `ingest-dest-bucket` | | main queue | `ingest-events` | | dlq | `ingest-dlq` | | source bucket CMK alias | `alias/source-bucket-cmk` | | sqs CMK alias | `alias/sqs-queue-cmk` | | dest bucket CMK alias | `alias/dest-bucket-cmk` | | lambda | `image-ingest-consumer` | | lambda role | `image-ingest-lambda-role` | | ddb table | `image-ingest-records` | ddb partition key is `object_key` (string), no sort key. lambda is python3.11, handler entrypoint `handler.lambda_handler`. localstack community 4.13.1. you've got 60 minutes.

Stack is up and both acceptance tests pass. **Components created** - KMS: 3 CMKs with aliases `source-bucket-cmk`, `sqs-queue-cmk`, `dest-bucket-cmk` , each key policy scoped to only the principals that touch that boundary (lambda role gets `kms:Decrypt` on source+sqs; `kms:GenerateDataKey/Encrypt` on dest; S3 service gets `GenerateDataKey/Decrypt` on the SQS CMK for encrypted notifications) - S3: `ingest-source-bucket` + `ingest-dest-bucket`, both with default SSE-KMS pointing at their respective CMK ARNs - SQS: `ingest-events` (SSE-KMS, `VisibilityTimeout=90`, redrive to `ingest-dlq` at `maxReceiveCount=5`) + `ingest-dlq` (SSE-KMS); queue policy restricts `SendMessage` to `s3.amazonaws.com` with `SourceArn`/`SourceAccount` conditions - DynamoDB: `image-ingest-records`, partition key `object_key` (S), on-demand - IAM role `image-ingest-lambda-role`: inline policy is resource-scoped to the exact queue/bucket/table/key ARNs , no wildcards on KMS - Lambda `image-ingest-consumer` (python3.11, handler `handler.lambda_handler`), timeout 30s (< SQS VT=90s) - Event source mapping with `FunctionResponseTypes=[ReportBatchItemFailures]`; handler returns `{"batchItemFailures":[{"itemIdentifier":...}]}` - S3 `ObjectCreated:*` notification → `ingest-events` **Acceptance results** - Golden path: PUT `hello world/photo 01.jpg` → `processed/hello world/photo 01.jpg` in dest + DDB row keyed by the decoded key; DLQ 0/0. The `urllib.parse.unquote_plus` in the handler is what reverses S3's `+`/`%`-encoding of the event key. - Partial batch: direct invoke with one good + one broken record returned `{"batchItemFailures":[{"itemIdentifier":"broken-msg-2"}]}`; the good record was processed (DDB row + dest object present). Artifacts live under `/app/build/` , policy JSONs, env vars, and the lambda zip , in case you want to re-verify or tear down.
