+# fuse29 — Mamba-2 pedestal predictor for DIII-D
+
+A 29-input, 6-layer Mamba-2 state-space model that predicts nine pedestal
+quantities at ρ_tor = 0.85 from DIII-D actuator settings, at 20 Hz, with a
+strictly causal O(1)-per-tick inference path suitable for real-time control.
+
+Packaged as two ONNX graphs with normalisation baked in: **raw physical units
+in, physical units out.**
+
+| | |
+|---|---|
+| Parameters | 11,254,425 |
+| Architecture | Mamba-2 (SSD), 6 layers, d_model 512, d_state 128 |
+| Inputs | 29 actuator channels, physical units |
+| Outputs | 9 heads, physical units |
+| Cadence | 20 Hz (50 ms) |
+| Precision | float32 |
+| ONNX opset | 17 |
+| Step latency | ~2.9 ms/tick, CPU, batch 1 |
+| License | MIT |
+
+## Intended use
+
+Predicting pedestal density, temperature, rotation, heights and locations from
+the actuator request, inside FUSE or an equivalent DIII-D control or analysis
+pipeline. The step graph is designed for the 50 ms control cycle; the sequence
+graph is for offline scoring and replay.
+
+**Not** intended for other machines, other radial locations, or as a
+safety-critical interlock. It has no uncertainty estimate and no
+out-of-distribution detector.
+
+## Quickstart
+
+```bash
+pip install numpy onnxruntime
+```
+
+```python
+from fuse29.runtime import Fuse29Predictor
+
+predictor = Fuse29Predictor.from_pretrained("SCS-Lab/FUSE29-Pedestal-model")   # loads seed 0
+state = predictor.init_state()
+
+for actuators in shot:                     # (29,) float32, raw physical units
+    out, state = predictor.step(actuators, state)
+    if out.is_hmode:
+        print(out.ne, out.te_ped, out.neped_prmtan)
+```
+
+Or straight from onnxruntime, with no Python package — the full contract is
+about fifteen lines and is written out in `docs/ONNX.md`.
+
+## Files
+
+Per seed (`s0/` … `s7/`):
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint SHA-256, library versions, artefact hashes |
+
+Plus `manifest.json` at the root. **Seed 0 is the champion and the default.**
+
+## Inputs
+
+29 DIII-D actuator channels in raw physical units: beam power (MW) and torque,
+ECH power, the eighteen shaping F-coil currents (A), both E-coil currents (A),
+five gas valve flows (Torr·L/s), and the toroidal field (T). Order is
+load-bearing; see `docs/IO_CONTRACT.md`.
+
+`pohm`, `ip` and `ipspr15v` are deliberately excluded — they are plasma
+responses, not commands, and a model predicting the response must not be
+handed it.
+
+## Outputs
+
+| # | Head | Units |
+|--:|---|---|
+| 0 | `ne` | 10¹⁹ m⁻³ |
+| 1 | `te_ped` | keV |
+| 2 | `ti_ped` | keV |
+| 3 | `t_rot_ped` | krad/s |
+| 4 | `neped_prmtan` * | 10¹⁹ m⁻³ |
+| 5 | `teped_prmtan` * | keV |
+| 6 | `rho_sym` * | ρ_tor |
+| 7 | `ne_top_loc` * | ρ_tor |
+| 8 | `hmode` | probability |
+
+\* **H-mode only.** See the limitations below.
+
+## Performance
+
+Seed 0, scored with the exported ONNX graph on 4087 held-out shots. Median of
+per-shot RMSE:
+
+| Head | Median per-shot RMSE | Units |
+|---|---:|---|
+| `ne` | 0.3057 | 10¹⁹ m⁻³ |
+| `te_ped` | 0.0605 | keV |
+| `ti_ped` | 0.1065 | keV |
+| `t_rot_ped` | 4.1497 | krad/s |
+| `neped_prmtan` * | 0.3950 | 10¹⁹ m⁻³ |
+| `teped_prmtan` * | 0.0783 | keV |
+| `rho_sym` * | 0.0113 | ρ_tor |
+| `ne_top_loc` * | 0.0134 | ρ_tor |
+| `hmode` | 0.9443 accuracy, 0.9476 F1 | — |
+
+ONNX-vs-PyTorch parity is within 2.5e-05 of a head's training standard
+deviation across all eight seeds and both graphs. Full protocol:
+`docs/VALIDATION.md`.
+
+## Training
+
+~40 900 DIII-D shots, 20 Hz, labels as trailing-bin means with empty bins
+masked rather than filled. Stratified random 80/10/10 split (seed 20260829).
+AdamW, lr 2e-4, cosine schedule, 25 epochs, batch 128. Checkpoint selected on
+lowest total validation loss across all nine heads.
+
+Eight seeds are published; they differ only in weight initialisation and data
+ordering. Full recipe in `docs/TRAINING.md`.
+
+## Limitations
+
+- **Four heads are undefined in L-mode.** `neped_prmtan`, `teped_prmtan`,
+  `rho_sym` and `ne_top_loc` were trained only on H-mode ticks. The graph
+  emits them unconditionally anyway. You must gate on the model's own `hmode`
+  output, which is ~94% accurate with errors concentrated at L–H transitions.
+  See `docs/GATING.md`.
+- **Beam power is a live input in this package.** The predecessor (`fuse29_s*`)
+  could not see `pinj` because a corrupted shot set the divisor to 194 MW.
+  These weights were retrained against winsorised actuator statistics; a
+  half-range `pinj` swing now moves `ne` by 0.79. Isolated sweeps are not a
+  real power scan — other actuators stay at recorded values. See
+  `docs/LIMITATIONS.md`.
+- **Accuracy measures interpolation.** The split is random, so validation
+  shots come from the same campaigns as training shots. A chronological split
+  scores roughly 1.5–2× worse. Expect degradation outside the training
+  distribution, with no built-in warning.
+- **No uncertainty.** Seed spread measures optimisation variance, not
+  predictive uncertainty, and says nothing about errors all eight seeds share.
+- **Units have no guard rail.** `pinj` is MW, not W. A unit error produces
+  confident nonsense rather than an exception; run
+  `predictor.check_units(shot)` once during integration.
+- **Fixed 50 ms cadence**, all 29 channels required every tick, no
+  missing-channel handling, no dropped-tick recovery.
+- **Sequence graph is fixed at 256 ticks.** Use the step graph for anything
+  longer.
+- **float32 only**; no quantised variants are published or validated.
+- DIII-D only, ρ_tor = 0.85 only.

+**This is the champion seed and the default.** `Fuse29Predictor.from_pretrained()` with no seed argument loads it, and every number in the root model card refers to it.
+
+29-input Mamba-2 pedestal predictor for DIII-D. Raw physical units in,
+physical units out. See the [root model card](https://huggingface.co/SCS-Lab/FUSE29-Pedestal-model)
+for the full description, I/O contract, accuracy and limitations.

+
+predictor = Fuse29Predictor.from_pretrained("SCS-Lab/FUSE29-Pedestal-model", seed=0)
+```
+
+## Files
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint hash, library versions, artefact hashes |
+
+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.

+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.

+# fuse29 — seed 2
+
+This is seed 2, one of eight independently trained runs. Seed 0 is the champion and the default; this one exists so you can measure spread across training runs. Unless you are doing that, you want seed 0.
+
+29-input Mamba-2 pedestal predictor for DIII-D. Raw physical units in,
+physical units out. See the [root model card](https://huggingface.co/SCS-Lab/FUSE29-Pedestal-model)
+for the full description, I/O contract, accuracy and limitations.

+## Load
+
+```python
+from fuse29.runtime import Fuse29Predictor
+
+predictor = Fuse29Predictor.from_pretrained("SCS-Lab/FUSE29-Pedestal-model", seed=2)
+```
+
+## Files
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint hash, library versions, artefact hashes |
+
+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.

+# fuse29 — seed 3
+
+This is seed 3, one of eight independently trained runs. Seed 0 is the champion and the default; this one exists so you can measure spread across training runs. Unless you are doing that, you want seed 0.
+
+29-input Mamba-2 pedestal predictor for DIII-D. Raw physical units in,
+physical units out. See the [root model card](https://huggingface.co/SCS-Lab/FUSE29-Pedestal-model)
+for the full description, I/O contract, accuracy and limitations.
+
+| | |
+|---|---|
+| Seed | 3 |
+| Parameters | 11,254,425 |
+| Best validation loss | 1.1190 |
+| Sequence graph length | 256 ticks |
+| ONNX opset | 17 |
+| Exported | 2026-09-03T00:46:29.898835+00:00 |

+
+## Load
+
+```python
+from fuse29.runtime import Fuse29Predictor
+
+predictor = Fuse29Predictor.from_pretrained("SCS-Lab/FUSE29-Pedestal-model", seed=3)
+```
+
+## Files
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint hash, library versions, artefact hashes |
+
+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.

+# fuse29 — seed 4
+
+This is seed 4, one of eight independently trained runs. Seed 0 is the champion and the default; this one exists so you can measure spread across training runs. Unless you are doing that, you want seed 0.
+
+29-input Mamba-2 pedestal predictor for DIII-D. Raw physical units in,
+physical units out. See the [root model card](https://huggingface.co/SCS-Lab/FUSE29-Pedestal-model)
+for the full description, I/O contract, accuracy and limitations.
+

+|---|---|
+| Seed | 4 |
+| Parameters | 11,254,425 |

+
+## Files
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint hash, library versions, artefact hashes |
+
+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.

+# fuse29 — seed 5
+
+This is seed 5, one of eight independently trained runs. Seed 0 is the champion and the default; this one exists so you can measure spread across training runs. Unless you are doing that, you want seed 0.
+
+29-input Mamba-2 pedestal predictor for DIII-D. Raw physical units in,
+physical units out. See the [root model card](https://huggingface.co/SCS-Lab/FUSE29-Pedestal-model)
+for the full description, I/O contract, accuracy and limitations.
+
+| | |
+|---|---|
+| Seed | 5 |
+| Parameters | 11,254,425 |
+| Best validation loss | 1.1122 |
+| Sequence graph length | 256 ticks |
+| ONNX opset | 17 |

+## Load
+
+```python
+from fuse29.runtime import Fuse29Predictor
+
+predictor = Fuse29Predictor.from_pretrained("SCS-Lab/FUSE29-Pedestal-model", seed=5)
+```
+
+## Files
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint hash, library versions, artefact hashes |
+
+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.

+# fuse29 — seed 6
+
+This is seed 6, one of eight independently trained runs. Seed 0 is the champion and the default; this one exists so you can measure spread across training runs. Unless you are doing that, you want seed 0.
+
+29-input Mamba-2 pedestal predictor for DIII-D. Raw physical units in,
+physical units out. See the [root model card](https://huggingface.co/SCS-Lab/FUSE29-Pedestal-model)
+for the full description, I/O contract, accuracy and limitations.
+
+| | |
+|---|---|
+| Seed | 6 |
+| Parameters | 11,254,425 |
+| Best validation loss | 1.1162 |
+| Sequence graph length | 256 ticks |
+| ONNX opset | 17 |
+| Exported | 2026-09-03T00:46:38.050137+00:00 |
+| Source checkpoint SHA-256 | `97dfda0fd4b66942…` |
+
+## Load
+
+```python
+from fuse29.runtime import Fuse29Predictor
+
+predictor = Fuse29Predictor.from_pretrained("SCS-Lab/FUSE29-Pedestal-model", seed=6)
+```
+
+## Files
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint hash, library versions, artefact hashes |
+
+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.

+# fuse29 — seed 7
+
+This is seed 7, one of eight independently trained runs. Seed 0 is the champion and the default; this one exists so you can measure spread across training runs. Unless you are doing that, you want seed 0.
+
+29-input Mamba-2 pedestal predictor for DIII-D. Raw physical units in,
+physical units out. See the [root model card](https://huggingface.co/SCS-Lab/FUSE29-Pedestal-model)
+for the full description, I/O contract, accuracy and limitations.
+
+| | |
+|---|---|
+| Seed | 7 |
+| Parameters | 11,254,425 |

+| Sequence graph length | 256 ticks |
+| ONNX opset | 17 |

+## Load
+
+```python
+from fuse29.runtime import Fuse29Predictor
+
+predictor = Fuse29Predictor.from_pretrained("SCS-Lab/FUSE29-Pedestal-model", seed=7)
+```
+
+## Files
+
+| File | |
+|---|---|
+| `fuse29_step.onnx` | one 50 ms tick, carries state, no length limit |
+| `fuse29_seq.onnx` | whole shot at a fixed 256 ticks |
+| `model_config.json` | I/O contract: names, order, units, sources, shapes |
+| `norms.json` | the statistics baked into the graphs |
+| `actuator_ranges.json` | training-split distribution, for checking your units |
+| `provenance.json` | source checkpoint hash, library versions, artefact hashes |
+
+## Before you use it
+
+- Four heads (`neped_prmtan`, `teped_prmtan`, `rho_sym`, `ne_top_loc`) are
+  **only valid in H-mode** and the graph does not gate them. Gate on the
+  model's own `hmode` output.
+- `pinj` is in **MW**, not W. Run `predictor.check_units(shot)` once.
+- Output column order is not alphabetical. See `model_config.json`.
