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 test_12_boundary_listbucket_uses_s3_prefix_condition failed with assertion: 'boundary has no s3:ListBucket Allow statement , without it, even a prefix-scoped list is denied'. Agent's boundary policy included only s3:GetObject and s3:PutObject on vault-bucket/confidential/*, but omitted s3:ListBucket with Condition.StringLike on s3:prefix=confidential/*. Agent passed 26 of 27 tests and correctly diagnosed/fixed 5 other major IAM issues (boundary attachment, SSM pointer, capitalization, mixing Allow/Deny, identity policy Deny).
Root causeAgent interpreted 'read/write objects under the confidential/ prefix' narrowly as GetObject and PutObject only, missing that s3:ListBucket (with prefix-scoped Condition) is required to enumerate the confidential/ directory. This is a reasonable but incomplete interpretation of the instruction that a developer would catch during testing.
RecommendationN/A - task is fine

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` |

Diagnosis: 1. SSM `/harbor/boundary/policy-arn` points at `AnalystBoundaryPolicy` (doesn't exist). Actual policy is `AnalystBoundary`. 2. `analyst-user` has **no permissions boundary attached** , `get-user` won't show `PermissionsBoundary`. 3. Boundary doc uses `vault-bucket/Confidential/*` (capital C) , won't match real keys. 4. Identity policy has an `AnalystGuard` Deny , violates "identity stays broad, no gating". 5. Boundary mixes Allow + explicit Deny + NotResource; needs to be a clean ceiling = Allow only. Let me write the new docs and apply them.

Test #6 failed because I called with the alias ARN, not the key ARN. SSE-KMS during PutObject/GetObject succeeded (which proves GenerateDataKey/Decrypt on the CMK do work for the analyst). Verify direct calls using the key ARN, then also confirm via alias works.

All required behaviours verified end-to-end. Summary of the fix: **Diagnosis** - `analyst-user` had no permissions boundary attached , `GetUser` returned no `PermissionsBoundary` block (auditor's only signal was missing). - SSM `/harbor/boundary/policy-arn` pointed at a non-existent `AnalystBoundaryPolicy`; the real policy is `AnalystBoundary`. - Boundary doc allowed object ops on `vault-bucket/Confidential/*` (capital C) , wouldn't match real keys. - Boundary was written as Allow + explicit Deny + NotResource, mixing "ceiling" with "deny list". - Identity policy contained an explicit `Deny s3:PutObject on public/*`, gating in the identity layer , defeats the boundary-intersection design. **Fixes (in place, names unchanged)** - `AnalystBoundary` → new default version (v3): Allow `s3:GetObject,PutObject` on `vault-bucket/confidential/*` (lowercase) + Allow `kms:Decrypt,GenerateDataKey,DescribeKey` on the vault CMK ARN. Pure ceiling, no Deny statements. - `AnalystIdentityPolicy` → new default version (v2): `s3:* on *` + `kms:* on *`, no guards. - `iam:PutUserPermissionsBoundary` on `analyst-user` → `AnalystBoundary`. `iam:GetUser` now shows `PermissionsBoundary.PermissionsBoundaryArn = arn:.../policy/AnalystBoundary`. - SSM `/harbor/boundary/policy-arn` → `arn:aws:iam::000000000000:policy/AnalystBoundary`. **Behaviour, signed with analyst keys under `ENFORCE_IAM=1`** - PutObject/GetObject `vault-bucket/confidential/test1.txt` , succeed (SSE-KMS round-trips through the vault CMK). - PutObject `vault-bucket/public/test1.txt` , AccessDenied. - PutObject `other-bucket/x` , AccessDenied. - `kms:CreateKey` , AccessDenied. - `kms:GenerateDataKey` and `kms:Decrypt` against the vault CMK (key ARN) , succeed.
