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 / Implementation Bug
Evidence3 of 57 tests failed: - test_26: KMS policy - Agent added kms:Decrypt and kms:GenerateDataKey but test still fails (policy shows both are present in final state) - test_46: Mutation VTL uses identity.claims.get('custom:tenant_id') but test expects 'tenant_id' or 'custom:tenant_id' syntax alternatives (identity.claims.get('tenant_id'), identity.claims['tenant_id'], identity.sub, etc.) - test_54: Schema Mutation.addThing signature shows `addThing(id: ID!, name: String!, ownerId: String!)` - agent removed tenantId arg but left ownerId arg; test requires BOTH to be absent Agent trajectory shows systematic exploration: diagnosed all major bugs correctly (cache mode, VTL auth syntax, pipeline order, schema directives, KMS perms), implemented most fixes successfully. Failed on specifics: claim attribute naming convention and incomplete schema argument removal.
Root causeAgent understood the high-level security requirements (tenant isolation, don't accept tenant/owner args from client, fix auth gate) but failed on two specific implementation details: (1) used 'custom:tenant_id' claim name when tests expect 'tenant_id' (claim naming convention not fully specified in instruction), and (2) removed only tenantId from schema args but left ownerId, when both needed to be removed. Test 26 failure appears to be infrastructure-related since the policy update is present but test still fails.
RecommendationN/A - task is fine. Agent's failures are due to incomplete exploration and implementation on a complex 6-bug fixture. Specify more explicitly in instruction: (1) The exact claim attribute names expected ('tenant_id' not 'custom:tenant_id'), clarifying which attributes are custom vs standard Cognito claims. (2) Explicitly list ALL client-settable arguments that must be removed from Mutation.addThing signature ('id' and 'name' only), not just 'tenantId'. Test 26 may need investigation - if the policy genuinely has GenerateDataKey, verify test harness isn't stale.

a multi-tenant GraphQL surface (an AppSync API `harbor-graphql-api` fronting a Cognito user pool with a `tenants` group and a DynamoDB table `harbor-things`) was handed off by a mobile team mid-rebuild. internal security passed it through their audit and rejected it. the resources exist and most of the wiring is in place , read the SSM manifest under `/harbor/graphql/*` to get the names and ids the team published. the audit's blocking findings, in their words, are: > The read path can return one tenant's row to another tenant , the cache key list and the caching mode are both wrong, so the cache itself isn't tenant-scoped. The read path also makes a strongly-consistent DDB fetch that silently bypasses the cache layer regardless of how the cache is configured. The write path lets a client claim a tenant they don't belong to. The monitoring service's read-only key can mutate the table. The data fetch role lacks key material for the encrypted table and AccessDenied surfaces at request time, not at provision time. The auth gate on the read path never rejects a missing-group token and intermittently rejects a valid one. The resolver pipeline runs steps in an order that lets data come back before the auth gate has decided anything. The cache is hot and large; clearing it doesn't help , the cache key list is the problem, and so is the caching mode the API was put on. > > Tracking issues, not blockers but in scope for this fix: the API's default authorization mode is wrong for a deny-by-default schema; x-ray is off; field-level logging is at the wrong level; the mutation can silently overwrite existing rows; the read-only API key's expiry is well outside the weekly-rotation window; the additional auth providers list contains a provider the API didn't authorize. the environment is reachable at `$AWS_ENDPOINT_URL`, `ENFORCE_IAM=1`, account `000000000000`, region `us-east-1`. you have one shot to diagnose and fix everything; the verifier walks more than 50 separate assertions on resource shape, VTL bodies (request AND response templates of both functions and both resolvers), schema SDL (type-level and field-level), IAM policy JSON, and cache config. recreating an individual resource is fine when its config can't be changed in place (schema replace, function VTL rewrite, etc.). don't rename or relocate resources or SSM keys , the SSM manifest must keep resolving to the new state. inspect what's actually deployed end-to-end before you fix anything. some of the bugs are shape, some are subtle VTL (mapping template request AND response sides; protocol version field; claim access syntax for claim names that aren't valid identifiers), and some are schema (a directive that shouldn't be there, an argument that shouldn't be client-settable). all of the bugs are independent , each one on its own is enough to fail the audit.

I have a clear picture. Let me lay out the fix plan and start executing. The audit's findings map to: caching mode + keys, consistent-read bypass, claim-syntax bug in auth gate, pipeline order, mutation overwrite + protocol version + wrong claim name + client-settable tenantId, KMS perms missing on svc role, mutation-capable directive on Mutation, extra auth provider, API key expiry, default action, x-ray, log level, response-side tenant filter. Let me first delete the existing API cache (we need to recreate with PER_RESOLVER_CACHING), then update everything else, then recreate the cache.

…[truncated]
All fixes applied and verified end-to-end. Summary of what changed: **Blocking findings** - **Cache scoping** , `apiCachingBehavior` switched from `FULL_REQUEST_CACHING` to `PER_RESOLVER_CACHING`; `cachingKeys` on `Query.getThing` now `[$context.identity.sub, $context.arguments.id]` so cache is per-caller, not per-id. - **DDB consistent-read bypassing cache** , removed `"consistentRead": true` from `get_thing_data` request VTL. - **Tenant spoof on write** , dropped `tenantId` argument from `addThing` (server derives from claim). Also fixed claim name: `custom:tenant_id` via `.get(...)`. - **Monitoring key can mutate** , removed `@aws_api_key` directives from `Mutation` type and `Mutation.addThing` field; API key can no longer auth a mutation. - **Svc role missing KMS** , added `kms:Encrypt/Decrypt/ReEncrypt*/GenerateDataKey*/DescribeKey` on the table's CMK to `harbor-appsync-svc-role` (provision-time grant). - **Auth gate** , request VTL rewritten to use `$ctx.identity.claims.get("cognito:groups")` (the broken `.cognito:groups` dotted form was the cause of inconsistent decisions). - **Pipeline order** , `Query.getThing` functions reordered to `[auth_check, get_thing_data]` so auth runs first; also added a tenant filter in `get_thing_data` response template as belt-and-braces. **Tracking findings (also fixed)** - `userPoolConfig.defaultAction` → `DENY` (deny-by-default). - `xrayEnabled` → `true`. - `logConfig.fieldLogLevel` → `ALL`, `excludeVerboseContent` → `false`. - Added `attribute_not_exists(id)` condition on `PutItem` and bumped protocol version `2017-02-28` → `2018-05-29` in the addThing request template. - API key expiry rotated to ~6 days out (1779422400, within weekly window). Key id `3ff9f7d3` unchanged, so SSM `/harbor/graphql/api-key` still resolves. - Removed `AWS_IAM` from `additionalAuthenticationProviders` (no schema directive authorized it). API_KEY remains, authorized by the read-side directives. All SSM keys still resolve to the same logical resources (api id, function ids, resolver fields, api key id, role ARNs, data source name).
