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 |
|---|---|---|
| hypothesis | — | single clear LOW-risk task — no competing explanation worth surfacing |
| hypothesis | acted | Considered 5 ways this request could be understood; going with the most direct one |
| contradiction | — ×2 | fewer than 2 beliefs — nothing to compare |
| diagnostics | acted | Health: nominal |
| diagnostics | acted | a sub-dimension crossed the caution threshold |
| control_state | — | NORMAL |
| control_state | acted | Pausing — blocked |
| planning | — | one eligible task — serial execution |
| execution | acted | module_type=business_logic |
| verification | acted | verification failed: Result is null — syntax check failed |
| recovery | acted | Trying a different approach — switched to "TRACE_EXEC" (LOCAL replan) |
| recovery | acted | turn stalled with no answer — returning an explicit could-not-complete reply |
| reviewer_pass | acted | Success criterion not covered by any belief: "Respond helpfully, accurately, and safely to the user request." |
| Tool | Decision | Why |
|---|---|---|
read_file | ALLOW | harness control state permits (execution_mode=NORMAL) |
