The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
| Layer | Acted? | Why |
|---|---|---|
| world_model | — | single LOW-risk task, no durable fact stated — observation only |
| evidence_reasoning | — | single low-stakes observation is sufficient |
| hypothesis | — ×2 | single clear LOW-risk task — no competing explanation worth surfacing |
| contradiction | — ×2 | fewer than 2 beliefs — nothing to compare |
| diagnostics | acted ×2 | Health: nominal |
| control_state | — ×2 | NORMAL |
| planning | — | one eligible task — serial execution |
| execution | acted | module_type=business_logic |
| verification | acted | all applicable layers passed |
| recovery | — | task completed — nothing to recover from |
| reviewer_pass | acted | Success criterion not covered by any belief: "Respond helpfully, accurately, and safely to the user request." |
