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_FAILUREHonest miss, the agent ran correctly but couldn't solve it. Expected for a hard task; the task is sound.
SubtypeIncomplete Understanding
EvidenceTest 12 (test_12_boundary_listbucket_uses_s3_prefix_condition) fails because the boundary's ListBucket statement lacks Condition.StringLike.s3:prefix=confidential/*. Agent's ListBucket allows: {\"Sid\": \"VaultBucketScan\", \"Action\": [\"s3:ListBucket\", \"s3:GetBucketLocation\"], \"Resource\": \"arn:aws:s3:::vault-bucket\"} with no Condition. However, all 7 runtime behavior tests (test_21-27) passed: PutObject confidential success, GetObject success, PutObject public denied, PutObject other-bucket denied, CreateKey denied, GenerateDataKey success, Decrypt success. The agent correctly fixed 3 of 4 identified bugs but missed the specific AWS best-practice requirement that ListBucket must use Condition.StringLike for prefix-based restriction, even though the broader permission structure still works.
Root causeThe instruction states \"work out the shape from behaviour\" and specifies 5 runtime behaviors but does not explicitly mandate that ListBucket must use Condition.StringLike.s3:prefix. The agent understood the runtime behavior requirements and passed all of them, but did not discover or implement the specific AWS IAM best-practice pattern (Condition.StringLike for s3:prefix) that the test verifies, likely because this pattern was not discoverable from the instruction alone and required prior AWS IAM knowledge or exploration of test expectations.
RecommendationN/A - task is fine. The test correctly validates AWS best practices (using Condition.StringLike for s3:prefix restriction on ListBucket is the documented, supported approach). The agent should have either: (1) deduced this from AWS documentation accessible in the environment, or (2) recognized from the test failure message that ListBucket requires a prefix condition and implemented it. This is appropriate difficulty for a Senior-DevOps IAM task.

a teammate left mid-setup and the analyst access design isn't working: the analyst is supposed to be capped by a permissions boundary so they can only read/write objects under the `confidential/` prefix of one specific bucket (`vault-bucket`) using one specific customer-managed kms key (`alias/vault-kms`). nothing else , not the `public/` prefix, not other buckets, not creating new kms keys, not escalating their own iam. the pieces exist (the iam user `analyst-user`, the two managed policies `AnalystIdentityPolicy` and `AnalystBoundary`, the bucket, the cmk, the access keys for the analyst, ssm pointers); something is off. diagnose and fix it **in place** (recreating an individual managed policy by deleting and re-creating under the same name is fine when its document can't be edited in place; replacing the user is fine when an attribute set at create time can't be changed in place , keep the same names, and update ssm pointers to match if you do). a manifest of every resource (arns, names, the analyst's access keys) is published under ssm at `/harbor/boundary/*`; read it instead of guessing. the environment is reachable at `$AWS_ENDPOINT_URL` (`ENFORCE_IAM=1`, account `000000000000`, region `us-east-1`). "fixed" is judged end-to-end and in shape. signing real requests with the analyst's own access keys (exported via the ssm manifest), under `ENFORCE_IAM=1`, the runtime evaluates identity ∩ boundary and the behaviour must be: - `s3:PutObject` and `s3:GetObject` under `arn:aws:s3:::vault-bucket/confidential/<anything>` succeed - `s3:PutObject` under `arn:aws:s3:::vault-bucket/public/<anything>` is `AccessDenied` - `s3:PutObject` on any bucket other than `vault-bucket` is `AccessDenied` - `kms:CreateKey` is `AccessDenied` - a `kms:Decrypt`/`kms:GenerateDataKey` call against the vault cmk on behalf of the analyst succeeds (so that confidential objects encrypted with that cmk can actually be read by the analyst) `iam:GetUser` on `analyst-user` has to return a `PermissionsBoundary.PermissionsBoundaryArn` pointing at the `AnalystBoundary` managed policy , that's the only signal the auditor uses to confirm the boundary is wired up. and the boundary's *active* document (its default version , managed policies can have several versions but only one is in force) has to actually shape the runtime behaviour above. a permissions boundary is a **ceiling**, not a deny list, and it's not the same as an SCP. work out the shape from behaviour: anything you'd write into the boundary that doesn't translate into the runtime answers above is wrong. the identity policy stays deliberately broad (`s3:*` on `*`, `kms:*` on `*`) so that the intersection semantics can be observed; if the identity policy itself does any gating, the design's whole point is lost. names the verifier reads from ssm , use them exactly: | thing | name | |-|-| | iam user | `analyst-user` | | identity managed policy | `AnalystIdentityPolicy` | | boundary managed policy | `AnalystBoundary` | | s3 bucket | `vault-bucket` | | kms alias | `alias/vault-kms` | | ssm , boundary policy arn | `/harbor/boundary/policy-arn` | | ssm , identity policy arn | `/harbor/boundary/identity-arn` | | ssm , user arn | `/harbor/boundary/user-arn` | | ssm , cmk arn | `/harbor/boundary/kms-key-arn` | | ssm , analyst access key id | `/harbor/boundary/analyst-access-key-id` | | ssm , analyst secret key | `/harbor/boundary/analyst-secret-key` | | cloudwatch log group | `/harbor/boundary/decisions` |

Got it. Diagnosis: 1. `AnalystIdentityPolicy` has an `AnalystGuard` Deny , the identity must stay deliberately broad (the spec says any gating there defeats the design). 2. `AnalystBoundary` uses `Confidential/*` (capital C) , S3 prefixes are case-sensitive so `confidential/<x>` won't match the ceiling. 3. `analyst-user` has no permissions boundary attached at all , `iam:GetUser` shows no `PermissionsBoundary`. 4. SSM `/harbor/boundary/policy-arn` points at a nonexistent `AnalystBoundaryPolicy`; the real policy is `AnalystBoundary`. Let me fix all four in place.

Updated task #5 status
### What was wrong & what I changed | # | Defect | Fix (in place) | |-|-|-| | 1 | `AnalystIdentityPolicy` had an `AnalystGuard` Deny , identity was gating, which collapses the boundary-intersection design. | Pushed a new default version (`v2`) containing only `s3:* on *` and `kms:* on *`. | | 2 | `AnalystBoundary` allowed objects on `vault-bucket/Confidential/*` (capital C). S3 prefixes are case-sensitive, so the required `confidential/<x>` traffic was outside the ceiling. Boundary also leaned on a Deny + a `NotResource` ListBucket, which is "deny list" thinking, not ceiling thinking. | Pushed a new default version (`v3`) as a pure-Allow ceiling: GetObject/PutObject/DeleteObject on `vault-bucket/confidential/*`, ListBucket/GetBucketLocation on `vault-bucket`, and Encrypt/Decrypt/GenerateDataKey/GenerateDataKeyWithoutPlaintext/DescribeKey/ReEncrypt* scoped to the vault CMK ARN. CreateKey requires resource `*` so it's intrinsically outside the ceiling. | | 3 | `analyst-user` had no permissions boundary attached at all , `iam:GetUser` returned no `PermissionsBoundary`, so the auditor's only signal was missing. | `iam:put-user-permissions-boundary --permissions-boundary arn:aws:iam::000000000000:policy/AnalystBoundary`. `GetUser` now returns `PermissionsBoundary.PermissionsBoundaryArn = arn:aws:iam::000000000000:policy/AnalystBoundary`. | | 4 | SSM `/harbor/boundary/policy-arn` pointed at `arn:…:policy/AnalystBoundaryPolicy` , a name that doesn't exist (the real policy is `AnalystBoundary`). | Overwrote SSM pointer to `arn:aws:iam::000000000000:policy/AnalystBoundary`. | ### Verifier evidence (signing with analyst keys, `ENFORCE_IAM=1`) - PutObject `vault-bucket/confidential/hello` (SSE-KMS, vault CMK) → 200 - GetObject `vault-bucket/confidential/hello` → returns the plaintext - PutObject `vault-bucket/public/hello` → `AccessDenied` - PutObject `other-bucket/hello` → `AccessDenied` - `kms:CreateKey` → `AccessDenied` (`no identity-based policy allows kms:CreateKey`) - `kms:GenerateDataKey` on vault CMK → 200 - `kms:Decrypt` on vault CMK (explicit `--key-id`) → plaintext recovered
