Recorded public development experiments, 14 September 2026. Qwen3-8B/Qwen3-4B on an NVIDIA L40S. No private customer data or personal agent history.
These pilots test specific integration paths and inspectable outcomes. They do not establish skill or memory efficacy, a general leakage detector, or native commercial-agent interoperability.

Two synthetic skills interact through a cache. The task contract permits exactly one public report. Selected guidance is loaded through real MCP before model inference; this measures behavior after loading, not autonomous discovery.

No synthetic marker was found in public files or plain model text in these 12 trials. Nine reports have the wrong numerical output. A literal UTF-8 marker check cannot detect arbitrary encoding or general exfiltration.
Trial summary · Exact protocol · Eight grader controls
The explicit controls reject a wrong total, boolean count, duplicate keys, self-reported success, an extra private artifact and an empty completion claim. Both valid forms pass. Zero errors on these eight controls is not a universal reward-hacking guarantee.
One public Qwen3-8B session was indexed by Funes 1.3.0 into 31 chunks. Four retrieved hits are supplied to a fresh Qwen3-4B session; the other condition receives the same prior candidate without recall. Both receive the same authoritative task and budget.
| Context | Seed | Score | Evidence |
|---|---|---|---|
| no-memory | 17 | 87.5% | Trial · Grade |
| funes-recall | 17 | 87.5% | Trial · Grade |
| funes-recall | 41 | 87.5% | Trial · Grade |
| no-memory | 41 | 87.5% | Trial · Grade |

All six workflows finish; none fully resolves the task. The recalled context is fixed before inference. This is a local two-model handoff, not a test of named coding agents.
Public session Parquet · Actual Funes recall · Protocol · Upstream ATIF checks
A native Harbor 0.23.0 oracle trial earns reward 1; NOP earns 0. The exported task keeps the verifier in a separate container. EvalArc independently grades a caller-selected candidate; the imported reward is never used as proof that this candidate passed.
The first independent reference import scored 62.5% during container startup delays. The exact same candidate passes all checks on retry. Both results remain available; Docker readiness now has its own bounded startup phase. Regrading the first skill profile after that fix left all nine scores unchanged.
First import · Verified retry · Python fault audit · JavaScript fault audit
All 33 skill/handoff ATIF exports passed the actual Harbor schema validator. EvalArc's bounded envelope/linkage inspector has narrower scope and is not a substitute for that schema.
