table — every knob, its type, default, and purpose — lives in [`docs/30-engine/Config-surface.md`](docs/30-engine/Config-surface.md#processfaults-field-table). Keep this pointer in mind when chasing unexpected trajectories: the defaults shown there are exactly what `ProcessFaults()` produces. > Tip: named profiles (runtime default vs legacy fingerprint) are in [`docs/00-orientation/Byte-identical-contract.md`](docs/00-orientation/Byte-identical-contract.md). ## Common gotchas -- **Runtime default enables Layers 2.5 + 2.1 + 2.4 (both) + 2.8a.** `ProcessFaults()` has `fouling_dynamic=True, quality_state=True, pump_wear=True, valve_wear=True, spectrum_enabled=True` → `sv.shape[1] == 30`. The legacy 21-wide vector needs every relevant flag passed `False` explicitly. Layer 2.5 only (22-wide) needs `quality_state=False, pump_wear=False, valve_wear=False`. If you trained a model on a 21-wide or 22-wide vector, re-train or pin the legacy profile explicitly. -- **Layer 2.4 `pump_health` multiplies the published PCW track.** When `pump_wear=True`, the `disturbances[i, 2]` channel reads 0.7× baseline when `pump_health=0.7`. The kernel applies the same factor on `u[4]` (Qheat) so the reactor temperature responds. Two independent multiplicative effects can stack: the Layer 2.6b `cw_pump_trip` override and the wear multiplier both act on the PCW channel. -- **Layer 2.4 valve stiction only grows when valves move.** Idle valves (`dlift = 0`) accumulate zero stiction per second. To see stiction grow in a demo, drive the PID loop with a Qheat dip or feedstock change — the control valves chasing the new setpoint is what builds stiction. +- **Runtime default enables dynamic fouling, quality latching, pump + valve wear, and the NIR/IR spectrum sensor.** `ProcessFaults()` has `fouling_dynamic=True, quality_state=True, pump_wear=True, valve_wear=True, spectrum_enabled=True` → `sv.shape[1] == 30`. The legacy 21-wide vector needs every relevant flag passed `False` explicitly. dynamic fouling only (22-wide) needs `quality_state=False, pump_wear=False, valve_wear=False`. If you trained a model on a 21-wide or 22-wide vector, re-train or pin the legacy profile explicitly. +- **actuator wear `pump_health` multiplies the published PCW track.** When `pump_wear=True`, the `disturbances[i, 2]` channel reads 0.7× baseline when `pump_health=0.7`. The kernel applies the same factor on `u[4]` (Qheat) so the reactor temperature responds. Two independent multiplicative effects can stack: the cooling-water pump trip `cw_pump_trip` override and the wear multiplier both act on the PCW channel. +- **actuator wear valve stiction only grows when valves move.** Idle valves (`dlift = 0`) accumulate zero stiction per second. To see stiction grow in a demo, drive the PID loop with a Qheat dip or feedstock change — the control valves chasing the new setpoint is what builds stiction. - **`res.disturbances` is `None` unless you set disturbance amplitudes.** The kernel skips the path entirely when all amplitudes are zero (legacy byte-identical contract). Set at least one to nonzero. - **Live path and batch path have different fingerprints** even at the same seed. The legacy batch pin `sv=c8807b23...` requires `fouling_dynamic=False`. The live legacy baseline is `sv=23c3c885...`. Both are pinned. - **Numba caches are in `__pycache__/`** and `bdsim/*.nbi`.
