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.

EvidenceAgent trajectory shows systematic diagnosis and correct fixes: (1) set AnalystBoundary v2 as default and deleted v1, (2) created clean AnalystIdentityPolicy v2 without the gating Deny, (3) attached boundary via put-user-permissions-boundary, (4) fixed SSM pointer. All 27 tests pass, including test_03_boundary_attached_via_get_user, test_21_analyst_can_put_to_confidential_prefix, test_22_analyst_cannot_put_to_public_prefix, test_23_analyst_cannot_create_kms_key, test_27_boundary_default_version_reflects_the_runtime_intended_shape. Agent verified with analyst's own keys under ENFORCE_IAM=1.
Root causeAgent correctly identified that the IAM setup had four interconnected bugs: wrong default boundary version, identity policy doing its own gating, missing boundary attachment, and wrong SSM pointer. The agent applied proper in-place fixes that preserved resource names and verified end-to-end behavior, passing all tests.

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` |

I have a clear picture. Issues found: 1. **Boundary policy default version**: `AnalystBoundary` has v1 (wrong: capital-C `Confidential/*`, broken NotResource, `kms:*` instead of needed ops) as default, but **v2 is already correct** , just not the default. Need to set v2 as default. 2. **Identity policy is gating**: `AnalystIdentityPolicy` has an extra `Deny` on `s3:PutObject` to `public/*` , task says the identity policy must stay broad. Need to drop the deny. 3. **No boundary attached to the user**: `iam:GetUser` won't report one. Need `put-user-permissions-boundary`. 4. **SSM `/harbor/boundary/policy-arn` is wrong** , points to nonexistent `AnalystBoundaryPolicy`. Should point to `AnalystBoundary`. All fixable in place. Executing now.

KMS failures are odd , identity has `kms:*` on `*` and boundary allows GenerateDataKey/Decrypt on the CMK. Let me verify the identity doc is what I think, and check what happened with the PutObject confidential.

GenerateDataKey works by key ID/ARN; the alias resolution was a localstack quirk. Let me confirm Decrypt similarly, and also confirm cross-bucket fails not because the bucket is missing.

All behaviors verify end-to-end. Done. **What was broken** 1. **`AnalystBoundary` default version was v1** , wrong shape (capital-C `Confidential/*`, busted `NotResource` on bucket-level `ListBucket`, `kms:*` instead of just the needed crypto ops). v2 was already the correct ceiling but not the default. 2. **`AnalystIdentityPolicy` was doing its own gating** , extra `Deny s3:PutObject` on `vault-bucket/public/*`. The design needs the identity policy to stay broad so the boundary intersection does the shaping. 3. **No permissions boundary attached to `analyst-user`** , `iam:GetUser` reported no `PermissionsBoundary`. 4. **SSM `/harbor/boundary/policy-arn` pointed to a nonexistent `AnalystBoundaryPolicy`** instead of `AnalystBoundary`. **Fixes (all in place, names preserved)** - `aws iam set-default-policy-version AnalystBoundary v2` (then deleted stale v1). - New `AnalystIdentityPolicy` version (v2) with just `s3:* on *` and `kms:* on *`, set as default; deleted v1. - `aws iam put-user-permissions-boundary --user-name analyst-user --permissions-boundary …/AnalystBoundary`. - Overwrote `/harbor/boundary/policy-arn` to the real `…:policy/AnalystBoundary`. **Verified with the analyst's keys, `ENFORCE_IAM=1`** - `iam:GetUser` → `PermissionsBoundaryArn = …:policy/AnalystBoundary` ✓ - PUT/GET `vault-bucket/confidential/test.txt` (SSE-KMS via `alias/vault-kms`) ✓ - PUT `vault-bucket/public/*` → AccessDenied ✓ - PUT `some-other-bucket/*` → AccessDenied ✓ - `kms:CreateKey` → AccessDenied ✓ - `kms:GenerateDataKey` / `kms:Decrypt` on the vault CMK → success ✓
