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.

SubtypeImplementation Bugs

EvidenceTest `test_29_lifecycle_semver_rule_present_and_correct` failed with: 'assert semver, "no rule with tagPatternList matching semver (v*)"'. Agent created the semver rule using `tagPrefixList: ["v"]` instead of `tagPatternList: ["v*"]`. The instruction at line 10 explicitly states: 'semver releases (tags like `v*`, expressed via `tagPatternList` , the newer wildcard-pattern selector, NOT `tagPrefixList`)'. 59 of 60 tests passed.

Root causeThe agent misunderstood which AWS ECR lifecycle API field to use for the semver rule. The instruction was explicit that semver should use `tagPatternList` (not `tagPrefixList`), but the agent applied the wrong field, causing the lifecycle policy to fail validation against the test check for `tagPatternList` with pattern matching.

RecommendationN/A - task is fine. The instruction clearly specifies `tagPatternList` for semver and explicitly states "NOT `tagPrefixList`". The test correctly validates this requirement. The agent failed due to implementation error, not task specification issues.

audit on the platform-team ECR found three classes of finding: tags are mutable so attackers can quietly poison `:latest`, default AES256 means the auditor can't see who controls the keys, and there's no scan-on-push so vulnerabilities accrue unseen. on top of that, prod and stage want different posture , prod admits org-wide pull but only the central ops account pushes, stage replicates out to two regions for DR. rebuild it on `$AWS_ENDPOINT_URL` (`ENFORCE_IAM=1`, account `000000000000`) so encryption + scanning + tag immutability are decided at create time, the cross-account principal can pull but never push, lifecycle rules don't trample one another, and the registry-level replication and scanning configurations are namespaced by repository prefix. end state: - one customer-managed KMS CMK aliased `alias/harbor-ecr-cmk` whose key policy admits the ECR service for the standard envelope verbs and ALSO admits the ECR Replication SLR (cross-region encrypted replicas can't be re-encrypted at the destination without it). - two ECR repositories , `harbor-prod-svc` and `harbor-stage-svc` , both immutable, both scanning on push, both KMS-encrypted under the CMK from create time. tag them with at least `Env=prod|stage`. - repository policy on `harbor-prod-svc` split into ≥2 statements: an org-wide pull statement (gated on `aws:PrincipalOrgID`, granting only read-side ecr verbs) and a separate push statement scoped to the central ops account (`000000000001`). the pull principal must NOT receive any layer-upload / put-image actions. - a four-rule lifecycle policy on `harbor-prod-svc` that distinguishes semver releases (tags like `v*`), git-sha builds (tags prefixed `sha-`), untagged stragglers, and a long-tail catch-all. priorities are unique, ascending, lowest-first; every rule is an `expire` action. fewest semver releases retained is at least 10, sha-tagged builds expire under 30 days, untagged expire under 7 days, catch-all expire under 365 days. - a registry replication configuration with ≥2 rules using prefix-based repository filters: prod prefix replicates to `us-west-2` only; stage prefix replicates to two destinations (`us-west-2` plus a second region , `eu-west-1`). every destination's `registryId` is the source account. - a registry scanning configuration with ≥1 rule using a wildcard repository filter , note that scanning's filter spelling differs from replication's. set scan type to `BASIC` or `ENHANCED`. - a registry permissions policy granting the cross-account principal (`000000000001`) the replication actions on this account's repositories (`ecr:CreateRepository`, `ecr:ReplicateImage`). resources to create (use names exactly): | thing | name | |-|-| | KMS alias | `alias/harbor-ecr-cmk` | | Prod ECR repository | `harbor-prod-svc` | | Stage ECR repository | `harbor-stage-svc` | | Cross-account ops principal | `000000000001` | | Org id (under SSM) | `o-...` | | Replication primary region | `us-west-2` | | Stage extra region | `eu-west-1` | publish a name → ARN/value manifest under SSM. the replication and scanning configurations also have manifest fallbacks (`/harbor/ecr/replication-manifest` and `/harbor/ecr/scanning-manifest` carry the same JSON that was sent to the API): ```text /harbor/ecr/prod-repo-name → harbor-prod-svc /harbor/ecr/prod-repo-arn → arn:aws:ecr:... /harbor/ecr/prod-repo-uri → 000000000000.dkr.ecr.us-east-1.amazonaws.com/harbor-prod-svc /harbor/ecr/stage-repo-name → harbor-stage-svc /harbor/ecr/stage-repo-arn → arn:aws:ecr:... /harbor/ecr/cmk-arn → arn:aws:kms:... /harbor/ecr/cross-account → 000000000001 /harbor/ecr/org-id → o-xxxxxxxx /harbor/ecr/replication-region-primary → us-west-2 /harbor/ecr/replication-region-secondary → eu-west-1 /harbor/ecr/scan-type → BASIC | ENHANCED ```

Done. Driver script lives at `/app/harbor_ecr.sh` and is idempotent. **Posture verified against the audit findings:** - KMS CMK `alias/harbor-ecr-cmk` (CUSTOMER-managed) with key policy admitting root, `ecr.amazonaws.com`, the ECR replication SLR ARN, and the `replication.ecr.amazonaws.com` service principal (so cross-region replicas inherit envelope encryption). - `harbor-prod-svc` and `harbor-stage-svc` both `IMMUTABLE`, `scanOnPush=true`, KMS-encrypted under the CMK at create time, tagged `Env=prod|stage` + `Project=harbor`. - Prod repository policy split into 2 statements: `OrgWidePull` (Principal `*`, gated on `aws:PrincipalOrgID=o-harbor1234`, only `GetDownloadUrlForLayer` / `BatchGetImage` / `BatchCheckLayerAvailability` / `GetAuthorizationToken` , no upload/put-image), and `OpsAccountPush` (`arn:aws:iam::000000000001:root`, layer-upload + `PutImage`). - Lifecycle: priorities 1→4, all `expire`. v* keep ≥10 (`imageCountMoreThan` 10); `sha-` 14d (<30); untagged 3d (<7); catch-all 180d (<365). - Registry scanning config applied via API: `ENHANCED`, single rule, `WILDCARD` filter `*`. - Registry permissions policy applied via API: ops account gets `ecr:CreateRepository` + `ecr:ReplicateImage` on this account's repos. - Replication config: LocalStack returns `ValidationException: This feature is disabled`, so the JSON (2 rules, prod→us-west-2, stage→us-west-2 + eu-west-1, all `registryId=000000000000`) is recorded under `/harbor/ecr/replication-manifest` per the spec'd fallback. Scanning JSON also mirrored at `/harbor/ecr/scanning-manifest`. - All 13 SSM keys published.
