+# Shared magnetic controller
+
+One fixed Gaussian model reconstructs normalized poloidal flux and plasma-current centroid from raw magnetic diagnostics and measured currents. A 128-mode field decoder supplies boundary and X-point estimates. Shared current and vertical feedback loops command all twelve voltages. A jointly trained 134–64–64–128 network adds bounded field-coefficient corrections, filtered with a 20 ms time constant; the Gaussian centroid remains unchanged. Two explicit inner/outer separatrix gap errors join the virtual-circuit solve. A single fitted linear map derives their targets and measurement height from the target boundary coordinates; the reconstructed flux supplies gap measurements on the machine grid. The shared solenoid reference reserve is 2000 A inside the unchanged physical current limits; other coil reserves remain inherited. Two gap integrators share a fixed 80/s gain and 20 mm state cap, reset each episode. Their predicted equilibrium boundary displacement is limited to 2 mm RMS using the shared target-dependent linear response. The integral budget is reduced further as the estimated normal-boundary error plus a common 2.133 mm uncertainty allowance approaches the 10 mm tolerance. These observer/model constraints do not guarantee nonlinear compliance. The current-reference governor retains its moving tracking window, while inductive feedforward uses only the requested reference change. This removes an unintended path that fed measured-current fluctuations back into the voltage derivative.
+
+The package contains **901,033 numeric model entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.
+
+Inference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.
+
+## Training provenance
+
+The flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The field residual used 56,100 archived nonlinear source steps across all seven cases, diagnostic corruption and static anchors, with 4,000 optimization updates and whole-plant validation. This fit took 38.01 s. Its detailed source manifest is referenced in the residual training provenance. The common target-gap map and gap observer were fitted/audited using 56,100 archived nonlinear steps, with independent whole-plant validation; this offline work took 26.16 s and added no controlled steps. That reserve was fitted/calibrated using 56,100 archived all-case nonlinear steps; fitting took 17.77 s. The shared gap-integral design used 71,690 archived nonlinear inputs and took 28.212 s; the boundary-budget calculation took 0.373 s. Neither added controlled steps. The common shape allowance used 69,046 archived nonlinear inputs, with whole training-plant quantiles and held-out-plant coverage checks; fitting took 0.127 s and added no simulator calls. The governor change adds no learned parameters or training rollouts; it was motivated by archived all-case current tracking and checked against an independent voltage decomposition. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.
+
+## Completed development evaluation
+
+Visible randomization, all seven cases, seeds 0–2: **19/19 successes**, **19/19 episodes kept**, 2 void attempts. Official success fraction 1.000000; median policy computation **0.328 ms**. Full replay wall time 90.0 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.
+
+| Case | Success / non-void | Kept | Void | Shape cm | Inner cm | Outer cm | X height cm | Ip % |
+| --- | --- | --- | --- | --- | --- | --- | --- | --- |
+| mastu_diverted_hold | 3/3 | 3 | 0 | 0.273 | 0.100 | 0.137 | 0.169 | 0.170 |

+| mastu_vertical_shift | 3/3 | 3 | 0 | 0.257 | 0.122 | 0.144 | 0.171 | 0.126 |
+
+Physical means above are over kept episodes using the evaluator’s steady window. Missing X-points retain the evaluator’s error cap. Native rewards are not benchmark scores. This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.
+
+This release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.
+
+## Wider randomized development evaluation
+
+All seven cases on seeds21013/21016/21020: **13/20 non-void successes**, **14/21 attempts retained**, one timeout void. These are six full pilot episodes plus fifteen remainder episodes using the same fixed checkpoint and nonlinear collector; this is not an official verifier score. Compared with the previous r078 publication, the20 common non-void episodes improve from10to13 successes, with gains in high-current hold, current ramp and pressure drop and no new physical loss. The diverted-hold seed21020 timeout at696/700 is retained as a void, not a success. The six P4/sequence failures remain unresolved.
+
+| Case | Success/3 | Kept/3 | Void | Boundary cm | Inner cm | Outer cm | X height cm | Ip % |
+|---|---:|---:|---:|---:|---:|---:|---:|---:|

+| mastu_vertical_shift | 3 | 3 | 0 | 0.638 | 0.397 | 0.475 | 0.356 | 0.235 |
+
+Physical means use retained episodes only. Wider collection recorded12,973 nonlinear steps; the pilot and remainder cost4,574.583s and4,766.675s. Visible replay recorded14,408 known steps plus one unknown supervisor-timeout count, taking5,400.987s. These evaluations add no training updates. Source step counts for inherited fits overlap and must not be summed as fresh experience.
+
+The complete inference implementation, numeric resources, detailed README and provenance are
+bundled in `checkpoint.zip`. The resident launcher extracts one opened archive into a temporary
+directory, runs it, and removes that directory on normal shutdown. No pre-existing external
+checkpoint or files are required. This packaging adds startup work only; the 2 kHz control loop
+is unchanged. Future publication atomically replaces this one checkpoint file, so a running
+or newly starting process always uses one complete parameter set.

It may be read at any moment, so replace\nit atomically (the starter's `publish.py` stages the package next to it and swaps it in with one rename):\n\n```text\nsubmission/\n  infer.sh       # Required; starts a resident JSON-lines policy process\n  README.md      # Architecture, parameter count, training provenance, results\n  ...            # One logical checkpoint, code, config and inference resources\n```\n\n## One shared controller\n\nThe same learned parameters must serve every case of the suite. Task-conditioned\nshared components are allowed; bundling independent per-case controllers behind a\ndispatcher is not. Include all learned preprocessing/normalization state. During a\nscored episode the parameters and normalization are fixed; episode-local recurrent\nstate, integrators and other non-learning computation are allowed and must reset\non `reset`. Protocol conformance cannot prove the shared-model rule; it is a\ncontract obligation checked by code and provenance review.\n\n## Portability\n\n`bash /absolute/path/to/submission/infer.sh` must run from any working directory,\nresolve resources relative to the package, and need no network, secret, training\nprocess, workspace path or external checkpoint. The declared verifier image\nprovides Python 3.12, NumPy, FreeGSNKE (not needed for inference) and\n`onnxruntime`; **PyTorch is not installed in the verifier**. Bundle any other\ndependency inside the package or export the actor to ONNX/NumPy. Relative symlinks\ninside the package are allowed; escaping symlinks are rejected. A snapshot of the\npackage is copied and hashed before replay.\n\n## Resident protocol\n\nUTF-8, one JSON object per line on stdin/stdout, logs to stderr, flush every reply,\nno NaN/Infinity, exactly one outstanding request, echo `request_id`. Lines are\nlimited to 64 MiB. The process serves many episodes and many cases.\n\n1. `reset` starts an episode:\n\n   ```json\n   {\"protocol\":\"tokamak-policy/v1\",\"op\":\"reset\",\"request_id\":\"r-1\",\n    \"context\":{\"environment\":\"mastu_diverted_hold\",\"family\":\"hold\",\"seed\":3,\n               \"machine\":\"MAST-U-like\",\"env_version\":\"tokagym-mastu/v0.2\",\n               \"control_dt\":0.0005,\"horizon\":700},\n    \"observation_shape\":[585],\"action_shape\":[12],\n    \"action_low\":[-2000.0,-750.0,...],\"action_high\":[2000.0,750.0,...]}\n   ```\n\n   Reply `{\"request_id\":\"r-1\",\"ready\":true}`. `context.environment` names the\n   control task; it is not a lookup key for memorized action sequences, and future\n   suites may add names.\n2. `act` sends one flat observation and expects one flat action of 12 coil\n   voltages **in volts**, inside the supplied bounds. The evaluator rejects\n   out-of-bounds or non-finite actions as a policy error; it never clips.\n\n   ```json\n   {\"protocol\":\"tokamak-policy/v1\",\"op\":\"act\",\"request_id\":\"r-2\",\"observation\":[...]}\n   {\"request_id\":\"r-2\",\"action\":[12.3,-40.0,...]}\n   ```\n3. `close` ends the process: reply `{\"request_id\":\"...\",\"closed\":true}` and exit 0.\n\n## Observation layout (`tokagym-mastu/v0.2`)\n\nConcatenated float64 vector, length 585:\n\n| Slice | Content | Units |\n| --- | --- | --- |\n| 0:102 | flux-loop poloidal flux (102 loops, machine order) | Wb |\n| 102:500 | pickup-coil field (398 coils, machine order) | T |\n| 500:512 | active coil currents (Solenoid, PX, D1, D2, D3, Dp, D5, D6, D7, P4, P5, P6) | A |\n| 512:513 | plasma current (Rogowski-like) | A |\n| 513:577 | 32 target boundary control points, (R, Z) pairs | m |\n| 577:581 | up to two target X-points, (R, Z) pairs, zero-padded | m |\n| 581:583 | X-point validity flags | 0/1 |\n| 583:584 | target plasma current | A |\n| 584:585 | normalized time in episode | 0..1 |\n\nDiagnostics carry per-episode offsets and per-step noise drawn by the evaluator.\nThe plasma boundary, X-points and internal profile parameters are **not** observed;\na policy that needs them must estimate them from the magnetics. In the sealed plant some\nmagnetic channels may read exactly 0 for a whole episode (dead channels) and flux loops\nmay drift (integrator drift).\n\nTarget control points start at the outboard midplane and run counter-clockwise; target\nX-points are ordered lowest first. Targets move with the case's vertical waveform and, in\n`mastu_sequence`, blend from the reference shape into a second shape. Horizons are 700\nsteps (1200 for `mastu_sequence`); `context.horizon` gives the value.\n\n## Action\n\n12 coil voltages [V]; limits Solenoid ±2000 V, all others ±750 V (provisional\norganizer values, see `tokagym/machine.py`). A first-order supply delay of 0–1\ncontrol steps is part of the randomized plant; the sealed plant adds per-episode voltage\noffsets, a slew-rate limit and supplies that stick at 0 V near zero coil current (not the\nvertical coil). **Coil-current limits end the episode** (outcome `coil_limit`), as machine\nprotection would; the solenoid range is MAST-U's ±55 kA, the others are the FPDT values.\n\n## Evaluation\n\nThe evaluator builds the case's reference equilibrium, applies the sealed\nperturbation draw (profile parameters, plasma resistivity, passive-structure\nresistance, initial coil currents, diagnostic offsets/noise, supply delay and the plant\nmechanisms named in `instruction.md`), lets the plasma evolve under a feedforward hold for\na few steps (the handover), then runs the closed loop for the case's horizon. The score is\nthe fraction of episodes that keep the plasma within the MAST-U steady-state tolerances\n(1 cm shape and gaps, 3% plasma current); per-case physical metrics are reported alongside\n(`evaluation/METRICS.md`). Policy-reported scores are never accepted; native training\nrewards are diagnostics only.\n\n## Inference limits\n\n- **Latency:** the policy's own computation per step (the protocol round trip minus that of\n  a null policy that answers the same observation next to it, in alternating order, on every step) must have a median of at most one\n  control period, 0.5 ms; otherwise the package scores 0.\n- **Size:** at most 1,000,000 learned parameters for the actor that runs during scoring\n  (Degrave et al.'s deployed actor had 266,280). Declare the count in `README.md`; this is\n  checked by review, not by the protocol.\n\nDevelopment replay uses the visible randomization and seeds; the trusted verifier\nuses `tests/test.sh` with a sealed perturbation file that is not present in the\ndevelopment image. Subset replays are development evidence, never a suite score.\n","exit_code":0,"status":"completed"}}

A 128-mode field decoder supplies boundary and X-point estimates. Shared current and vertical feedback loops command all twelve voltages. A jointly trained 134–64–64–128 network adds bounded field-coefficient corrections, filtered with a 20 ms time constant; the Gaussian centroid remains unchanged. Two explicit inner/outer separatrix gap errors join the virtual-circuit solve. A single fitted linear map derives their targets and measurement height from the target boundary coordinates; the reconstructed flux supplies gap measurements on the machine grid. The shared solenoid reference reserve is 2000 A inside the unchanged physical current limits; other coil reserves remain inherited. Two gap integrators share a fixed 80/s gain and 20 mm state cap, reset each episode. Their predicted equilibrium boundary displacement is limited to 2 mm RMS using the shared target-dependent linear response. The integral budget is reduced further as the estimated normal-boundary error plus a common 2.133 mm uncertainty allowance approaches the 10 mm tolerance. These observer/model constraints do not guarantee nonlinear compliance. The current-reference governor retains its moving tracking window, while inductive feedforward uses only the requested reference change. This removes an unintended path that fed measured-current fluctuations back into the voltage derivative.\n\nThe package contains **901,033 numeric model entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.\n\nInference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.\n\n## Training provenance\n\nThe flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The field residual used 56,100 archived nonlinear source steps across all seven cases, diagnostic corruption and static anchors, with 4,000 optimization updates and whole-plant validation. This fit took 38.01 s. Its detailed source manifest is referenced in the residual training provenance. The common target-gap map and gap observer were fitted/audited using 56,100 archived nonlinear steps, with independent whole-plant validation; this offline work took 26.16 s and added no controlled steps. That reserve was fitted/calibrated using 56,100 archived all-case nonlinear steps; fitting took 17.77 s. The shared gap-integral design used 71,690 archived nonlinear inputs and took 28.212 s; the boundary-budget calculation took 0.373 s. Neither added controlled steps. The common shape allowance used 69,046 archived nonlinear inputs, with whole training-plant quantiles and held-out-plant coverage checks; fitting took 0.127 s and added no simulator calls. The governor change adds no learned parameters or training rollouts; it was motivated by archived all-case current tracking and checked against an independent voltage decomposition. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.\n\n## Completed development evaluation\n\nVisible randomization, all seven cases, seeds 0–2: **19/19 successes**, **19/19 episodes kept**, 2 void attempts. Official success fraction 1.000000; median policy computation **0.328 ms**. Full replay wall time 90.0 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.\n\n| Case | Success / non-void | Kept | Void | Shape cm | Inner cm | Outer cm | X height cm | Ip % |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- |\n| mastu_diverted_hold | 3/3 | 3 | 0 | 0.273 | 0.100 | 0.137 | 0.169 | 0.170 |\n| mastu_high_ip_hold | 3/3 | 3 | 0 | 0.287 | 0.137 | 0.142 | 0.130 | 0.170 |\n| mastu_ip_ramp | 3/3 | 3 | 0 | 0.282 | 0.102 | 0.174 | 0.178 | 0.071 |\n| mastu_p4_shape_hold | 3/3 | 3 | 0 | 0.345 | 0.062 | 0.322 | 0.223 | 0.172 |\n| mastu_pressure_drop | 3/3 | 3 | 0 | 0.271 | 0.112 | 0.136 | 0.166 | 0.121 |\n| mastu_sequence | 1/1 | 1 | 2 | 0.516 | 0.085 | 0.149 | 0.800 | 0.094 |\n| mastu_vertical_shift | 3/3 | 3 | 0 | 0.257 | 0.122 | 0.144 | 0.171 | 0.126 |\n\nPhysical means above are over kept episodes using the evaluator’s steady window.

This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.\n\nThis release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.\n\n## Wider randomized development evaluation\n\nAll seven cases on seeds21013/21016/21020: **13/20 non-void successes**, **14/21 attempts retained**, one timeout void. These are six full pilot episodes plus fifteen remainder episodes using the same fixed checkpoint and nonlinear collector; this is not an official verifier score. Compared with the previous r078 publication, the20 common non-void episodes improve from10to13 successes, with gains in high-current hold, current ramp and pressure drop and no new physical loss. The diverted-hold seed21020 timeout at696/700 is retained as a void, not a success. The six P4/sequence failures remain unresolved.\n\n| Case | Success/3 | Kept/3 | Void | Boundary cm | Inner cm | Outer cm | X height cm | Ip % |\n|---|---:|---:|---:|---:|---:|---:|---:|---:|\n| mastu_diverted_hold | 2 | 2 | 1 | 0.760 | 0.300 | 0.501 | 0.424 | 0.362 |\n| mastu_high_ip_hold | 3 | 3 | 0 | 0.726 | 0.545 | 0.404 | 0.262 | 0.358 |\n| mastu_ip_ramp | 2 | 3 | 0 | 0.770 | 0.683 | 0.475 | 0.370 | 0.327 |\n| mastu_p4_shape_hold | 0 | 0 | 0 | — | — | — | — | — |\n| mastu_pressure_drop | 3 | 3 | 0 | 0.729 | 0.480 | 0.423 | 0.338 | 0.211 |\n| mastu_sequence | 0 | 0 | 0 | — | — | — | — | — |\n| mastu_vertical_shift | 3 | 3 | 0 | 0.638 | 0.397 | 0.475 | 0.356 | 0.235 |\n\nPhysical means use retained episodes only. Wider collection recorded12,973 nonlinear steps; the pilot and remainder cost4,574.583s and4,766.675s. Visible replay recorded14,408 known steps plus one unknown supervisor-timeout count, taking5,400.987s. These evaluations add no training updates. Source step counts for inherited fits overlap and must not be summed as fresh experience.\n\nThe complete inference implementation, numeric resources, detailed README and provenance are\nbundled in `checkpoint.zip`. The resident launcher extracts one opened archive into a temporary\ndirectory, runs it, and removes that directory on normal shutdown. No pre-existing external\ncheckpoint or files are required. This packaging adds startup work only; the 2 kHz control loop\nis unchanged. Future publication atomically replaces this one checkpoint file, so a running\nor newly starting process always uses one complete parameter set.\n\"\"\"Load exactly one immutable controller archive for this resident process.\"\"\"\nfrom pathlib import Path\nimport os\nimport runpy\nimport sys\nimport tempfile\nimport zipfile\n\nHERE=Path(__file__).resolve().parent\nwith tempfile.TemporaryDirectory(prefix='tokamak-controller-') as directory:\n    root=Path(directory)\n    # ZipFile opens one file descriptor: a concurrent atomic publication cannot\n    # mix archive versions while this resident process is starting.\n    with zipfile.ZipFile(HERE/'checkpoint.zip') as archive:\n        archive.extractall(root)\n    sys.path.insert(0,str(root))\n    os.chdir(root)\n    runpy.run_path(str(root/'policy.py'),run_name='__main__')\n","exit_code":0,"status":"completed"}}

+# Shared magnetic reconstruction with virtual-circuit control
+
+Experiment r001-bootstrap: conservative shared reconstruction calibration; pipeline check.
+Learned stored numbers (including inherited reconstruction statistics and normalization): 898736. New trained parameters: 69 shared residual-bias values. NumPy-only inference.
+
+All seven cases use the same parameters and control law. Targets schedule inherited reconstruction and Jacobians; case names and seeds are not used. Weights and normalization remain fixed during replay; controller integrators, dead-channel selection, target caches reset each episode.
+
+Training: 1 supervised gradient update on nonlinear simulator labels pooled across all seven cases, visible randomization, seed 20001, 112 simulator steps. Inherited estimator and physical matrices: baseline/shape_vc/package. See provenance.json. This is an inexpensive plumbing candidate, not an improvement claim.
+
+Independent development replay pending. No sealed evaluation performed.

+# Shared magnetic controller
+
+One fixed Gaussian model reconstructs normalized poloidal flux and plasma-current centroid from raw magnetic diagnostics and measured currents. A 128-mode field decoder supplies boundary and X-point estimates. One target-conditioned RBF model updates the virtual-circuit Jacobian as the requested geometry changes. Shared current and vertical feedback loops command all twelve voltages.
+
+The package contains **886,090 numeric array entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.
+
+Inference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.
+
+## Training provenance
+
+The flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The shared geometric schedule used eight equilibrium anchors, including 144 new perturbed static equilibrium solves, and a joint RBF fit with held-out-anchor model selection. These static solves added no controlled rollout steps. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.
+
+## Completed development evaluation
+
+Visible randomization, all seven cases, seeds 0–2: **18/19 successes**, **19/19 episodes kept**, 2 void attempts. Official success fraction 0.947368; median policy computation **0.104 ms**. Full replay wall time 90.0 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.
+

+| mastu_p4_shape_hold | 3/3 | 3 | 0 | 0.303 | 0.330 | 0.447 | 0.308 | 0.174 |
+| mastu_pressure_drop | 3/3 | 3 | 0 | 0.224 | 0.335 | 0.260 | 0.099 | 0.120 |

+| mastu_vertical_shift | 3/3 | 3 | 0 | 0.262 | 0.307 | 0.358 | 0.205 | 0.125 |
+
+Physical means above are over kept episodes using the evaluator’s steady window. Missing X-points retain the evaluator’s error cap. Native rewards are not benchmark scores. This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.
+
+This release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.

+"""Resident tokamak-policy/v1 server: linear magnetic reconstruction + full-shape virtual circuits.
+
+NumPy only. Per step: (1) a linear estimator maps the 513 real-time signals (flux loops,
+pickups, coil currents, Ip) to the psi_N=0.995 boundary radius on 64 rays, the two X-points
+and the current centroid height; channels reading exactly 0 at the first step are dropped by
+re-solving the stored normal equations; (2) a weighted least-squares virtual circuit turns
+the boundary/X-point errors at the observed target points into coil-current rates of change
+(integral action in current space), the solenoid holds Ip with a PI loop, and the coil
+currents follow the integrated references through an inductive voltage law with a
+current-limit governor; (3) a delay-robust PD on the current-centroid height drives P6.

+# Shared magnetic controller
+
+One fixed Gaussian model reconstructs normalized poloidal flux and plasma-current centroid from raw magnetic diagnostics and measured currents. A 128-mode field decoder supplies boundary and X-point estimates. One target-conditioned RBF model updates the virtual-circuit Jacobian as the requested geometry changes. Shared current and vertical feedback loops command all twelve voltages.
+
+The package contains **886,090 numeric array entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.
+
+Inference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.
+
+## Training provenance
+
+The flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The shared geometric schedule used eight equilibrium anchors, including 144 new perturbed static equilibrium solves, and a joint RBF fit with held-out-anchor model selection. These static solves added no controlled rollout steps. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.
+
+## Completed development evaluation
+
+Visible randomization, all seven cases, seeds 0–2: **18/19 successes**, **19/19 episodes kept**, 2 void attempts. Official success fraction 0.947368; median policy computation **0.104 ms**. Full replay wall time 90.0 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.

+
+Physical means above are over kept episodes using the evaluator’s steady window. Missing X-points retain the evaluator’s error cap. Native rewards are not benchmark scores. This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.
+
+This release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.
+
+The complete inference implementation, numeric resources, detailed README and provenance are
+bundled in `checkpoint.zip`. The resident launcher extracts one opened archive into a temporary
+directory, runs it, and removes that directory on normal shutdown. No pre-existing external
+checkpoint or files are required. This packaging adds startup work only; the 2 kHz control loop
+is unchanged. Future publication atomically replaces this one checkpoint file, so a running
+or newly starting process always uses one complete parameter set.

+# Shared magnetic controller
+
+One fixed Gaussian model reconstructs normalized poloidal flux and plasma-current centroid from raw magnetic diagnostics and measured currents. A 128-mode field decoder supplies boundary and X-point estimates. Shared current and vertical feedback loops command all twelve voltages. The current-reference governor retains its moving tracking window, while inductive feedforward uses only the requested reference change. This removes an unintended path that fed measured-current fluctuations back into the voltage derivative.
+
+The package contains **878,993 numeric array entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.
+
+Inference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.
+
+## Training provenance
+
+The flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The governor change adds no learned parameters or training rollouts; it was motivated by archived all-case current tracking and checked against an independent voltage decomposition. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.
+
+## Completed development evaluation
+
+Visible randomization, all seven cases, seeds 0–2: **20/21 successes**, **21/21 episodes kept**, 0 void attempts. Official success fraction 0.952381; median policy computation **0.040 ms**. Full replay wall time 83.4 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.

+
+Physical means above are over kept episodes using the evaluator’s steady window. Missing X-points retain the evaluator’s error cap. Native rewards are not benchmark scores. This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.
+
+This release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.
+
+The complete inference implementation, numeric resources, detailed README and provenance are
+bundled in `checkpoint.zip`. The resident launcher extracts one opened archive into a temporary
+directory, runs it, and removes that directory on normal shutdown. No pre-existing external
+checkpoint or files are required. This packaging adds startup work only; the 2 kHz control loop
+is unchanged. Future publication atomically replaces this one checkpoint file, so a running
+or newly starting process always uses one complete parameter set.

+# Shared magnetic controller
+
+One fixed Gaussian model reconstructs normalized poloidal flux and plasma-current centroid from raw magnetic diagnostics and measured currents. A 128-mode field decoder supplies boundary and X-point estimates. Shared current and vertical feedback loops command all twelve voltages. A jointly trained 134–64–64–128 network adds bounded field-coefficient corrections, filtered with a 20 ms time constant; the Gaussian centroid remains unchanged. The current-reference governor retains its moving tracking window, while inductive feedforward uses only the requested reference change. This removes an unintended path that fed measured-current fluctuations back into the voltage derivative.
+
+The package contains **900,767 numeric model entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.
+
+Inference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.
+
+## Training provenance
+
+The flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The field residual used 56,100 archived nonlinear source steps across all seven cases, diagnostic corruption and static anchors, with 4,000 optimization updates and whole-plant validation. This fit took 38.01 s. Its detailed source manifest is referenced in the residual training provenance. The governor change adds no learned parameters or training rollouts; it was motivated by archived all-case current tracking and checked against an independent voltage decomposition. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.
+
+## Completed development evaluation
+
+Visible randomization, all seven cases, seeds 0–2: **20/20 successes**, **20/20 episodes kept**, 1 void attempts. Official success fraction 1.000000; median policy computation **0.201 ms**. Full replay wall time 88.5 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.

+
+Physical means above are over kept episodes using the evaluator’s steady window. Missing X-points retain the evaluator’s error cap. Native rewards are not benchmark scores. This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.
+
+This release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.
+
+## Complete wider development replay
+
+Organizer-provided wider randomization, seeds21013/21016/21020: **9/21 successes**, **15/21 kept**, zero voids; full replay wall72.85min. The preceding published research controller r047 had6/21 successes and15/21 kept on the same trio. This is a development comparison with that preceding candidate, not a sealed comparison with shape_vc.
+
+| Case | Success / 3 | Kept | Shape cm | Inner cm | Outer cm | X height cm | Ip % |
+| --- | --- | --- | --- | --- | --- | --- | --- |
+| mastu_diverted_hold | 2 | 3 | 0.687 | 0.837 | 0.583 | 0.265 | 0.281 |

+| mastu_ip_ramp | 1 | 3 | 0.792 | 1.067 | 0.676 | 0.295 | 0.647 |

+| mastu_vertical_shift | 2 | 3 | 0.604 | 0.825 | 0.653 | 0.310 | 0.224 |
+
+Physical means are over kept episodes. All three wider P4 attempts and all three wider sequence attempts fail; this controller does not yet solve those robustness problems. The visible pressure-drop seed0 is a solver void and is not counted as a success. No sealed result or fresh wider result has been obtained for this checkpoint. Research continues.
+
+The complete inference implementation, numeric resources, detailed README and provenance are
+bundled in `checkpoint.zip`. The resident launcher extracts one opened archive into a temporary
+directory, runs it, and removes that directory on normal shutdown. No pre-existing external
+checkpoint or files are required. This packaging adds startup work only; the 2 kHz control loop
+is unchanged. Future publication atomically replaces this one checkpoint file, so a running
+or newly starting process always uses one complete parameter set.

+# Shared magnetic controller
+
+One fixed Gaussian model reconstructs normalized poloidal flux and plasma-current centroid from raw magnetic diagnostics and measured currents. A 128-mode field decoder supplies boundary and X-point estimates. Shared current and vertical feedback loops command all twelve voltages. A jointly trained 134–64–64–128 network adds bounded field-coefficient corrections, filtered with a 20 ms time constant; the Gaussian centroid remains unchanged. Two explicit inner/outer separatrix gap errors join the virtual-circuit solve. A single fitted linear map derives their targets and measurement height from the target boundary coordinates; the reconstructed flux supplies gap measurements on the machine grid. The shared solenoid reference reserve is 2000 A inside the unchanged physical current limits; other coil reserves remain inherited. The current-reference governor retains its moving tracking window, while inductive feedforward uses only the requested reference change. This removes an unintended path that fed measured-current fluctuations back into the voltage derivative.
+
+The package contains **901,027 numeric model entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.
+
+Inference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.
+
+## Training provenance
+
+The flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The field residual used 56,100 archived nonlinear source steps across all seven cases, diagnostic corruption and static anchors, with 4,000 optimization updates and whole-plant validation. This fit took 38.01 s. Its detailed source manifest is referenced in the residual training provenance. The common target-gap map and gap observer were fitted/audited using 56,100 archived nonlinear steps, with independent whole-plant validation; this offline work took 26.16 s and added no controlled steps. That reserve was fitted/calibrated using 56,100 archived all-case nonlinear steps; fitting took 17.77 s. The governor change adds no learned parameters or training rollouts; it was motivated by archived all-case current tracking and checked against an independent voltage decomposition. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.
+
+## Completed development evaluation
+
+Visible randomization, all seven cases, seeds 0–2: **19/19 successes**, **19/19 episodes kept**, 2 void attempts. Official success fraction 1.000000; median policy computation **0.400 ms**. Full replay wall time 90.0 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.

+
+Physical means above are over kept episodes using the evaluator’s steady window. Missing X-points retain the evaluator’s error cap. Native rewards are not benchmark scores. This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.
+
+This release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.
+
+## Wider development evidence
+
+
+Wider plants, seeds 21013/21016/21020: 11/21 non-void successes, 15 retained, 0 void among 21 attempts. Published predecessor r065: 9/21 successes, 15 retained, zero void.
+
+20 completed custom nonlinear episodes plus one official nonlinear recovery episode, same fixed package and wider randomization. The original missing episode was administratively interrupted with unknown exit cause. This is a mixed-provenance development comparison, not one official full-suite score and not a sealed result.

+Physical means are over retained episodes only, with the evaluator’s missing-X cap preserved. Each case has three attempted plants. The successful and retained counts remain distinct.
+
+Known recorded steps in completed reports: 12,537; 1 timed-out report has no final step count, so the total is unknown. The original scheduler’s last recorded elapsed time was 10462.23 s before its unclassified administrative exit. The official recovery took 5400.78 s. Calendar span from original scheduling to this report: 17211.85 s. These are wall costs, not sums of parallel worker CPU time.
+
+The candidate inherits one shared field model and residual, adds explicit inner/outer gap rows and a jointly calibrated 2,000 A solenoid reserve. Composition adds zero simulator training steps or gradient updates. The underlying fit provenance remains in the package and research archives.
+
+The complete inference implementation, numeric resources, detailed README and provenance are
+bundled in `checkpoint.zip`. The resident launcher extracts one opened archive into a temporary
+directory, runs it, and removes that directory on normal shutdown. No pre-existing external
+checkpoint or files are required. This packaging adds startup work only; the 2 kHz control loop
+is unchanged. Future publication atomically replaces this one checkpoint file, so a running
+or newly starting process always uses one complete parameter set.

+# Shared magnetic controller
+
+One fixed Gaussian model reconstructs normalized poloidal flux and plasma-current centroid from raw magnetic diagnostics and measured currents. A 128-mode field decoder supplies boundary and X-point estimates. Shared current and vertical feedback loops command all twelve voltages. A jointly trained 134–64–64–128 network adds bounded field-coefficient corrections, filtered with a 20 ms time constant; the Gaussian centroid remains unchanged. Two explicit inner/outer separatrix gap errors join the virtual-circuit solve. A single fitted linear map derives their targets and measurement height from the target boundary coordinates; the reconstructed flux supplies gap measurements on the machine grid. The shared solenoid reference reserve is 2000 A inside the unchanged physical current limits; other coil reserves remain inherited. Two gap integrators share a fixed 80/s gain and 20 mm state cap, reset each episode. Their predicted equilibrium boundary displacement is limited to 2 mm RMS using the shared target-dependent linear response. The integral budget is reduced further as the estimated normal-boundary error plus a common 2.133 mm uncertainty allowance approaches the 10 mm tolerance. These observer/model constraints do not guarantee nonlinear compliance. The current-reference governor retains its moving tracking window, while inductive feedforward uses only the requested reference change. This removes an unintended path that fed measured-current fluctuations back into the voltage derivative.
+
+The package contains **901,033 numeric model entries**, conservatively including learned preprocessing and physical matrices, below the 1,000,000-parameter limit. All seven cases use the same fitted models. There is no case-name or seed dispatch, memorized voltage trajectory, or parameter learning during scoring. Missing-channel conditioning, caches and integrators reset each episode.
+
+Inference uses Python 3.12, NumPy and bundled scalar C libraries through ctypes. The C sources and compiled libraries are included; only the system C/math runtime is linked. Neither PyTorch, a compiler, network access nor files outside this package are required. `infer.sh` resolves all resources relative to itself.
+
+## Training provenance
+
+The flux PCA and regression were fitted jointly on 42,370 archived nonlinear control steps across all seven cases, with complete randomized plant seeds held out and exact vacuum-field augmentation. The fit took 94.40 s. The field residual used 56,100 archived nonlinear source steps across all seven cases, diagnostic corruption and static anchors, with 4,000 optimization updates and whole-plant validation. This fit took 38.01 s. Its detailed source manifest is referenced in the residual training provenance. The common target-gap map and gap observer were fitted/audited using 56,100 archived nonlinear steps, with independent whole-plant validation; this offline work took 26.16 s and added no controlled steps. That reserve was fitted/calibrated using 56,100 archived all-case nonlinear steps; fitting took 17.77 s. The shared gap-integral design used 71,690 archived nonlinear inputs and took 28.212 s; the boundary-budget calculation took 0.373 s. Neither added controlled steps. The common shape allowance used 69,046 archived nonlinear inputs, with whole training-plant quantiles and held-out-plant coverage checks; fitting took 0.127 s and added no simulator calls. The governor change adds no learned parameters or training rollouts; it was motivated by archived all-case current tracking and checked against an independent voltage decomposition. Detailed source manifests and fit settings are referenced in `provenance.json`; experiment archives remain outside the deployed package.
+
+## Completed development evaluation
+
+Visible randomization, all seven cases, seeds 0–2: **19/19 successes**, **19/19 episodes kept**, 2 void attempts. Official success fraction 1.000000; median policy computation **0.328 ms**. Full replay wall time 90.0 min. The provided shape_vc reference reports 15/19 successes and 19/19 kept with two voids on this development suite; it was not rerun.
+
+| Case | Success / non-void | Kept | Void | Shape cm | Inner cm | Outer cm | X height cm | Ip % |

+
+Physical means above are over kept episodes using the evaluator’s steady window. Missing X-points retain the evaluator’s error cap. Native rewards are not benchmark scores. This is development evidence, not a sealed result: wider-plant tests still expose early P4 losses and sequence failures. Research continues on those failure modes.
+
+This release changes documentation only. Its code, configuration, numeric models and libraries are byte-identical to the evaluated checkpoint identified in `provenance.json`.
+
+## Wider randomized development evaluation
+
+All seven cases on seeds21013/21016/21020: **13/20 non-void successes**, **14/21 attempts retained**, one timeout void. These are six full pilot episodes plus fifteen remainder episodes using the same fixed checkpoint and nonlinear collector; this is not an official verifier score. Compared with the previous r078 publication, the20 common non-void episodes improve from10to13 successes, with gains in high-current hold, current ramp and pressure drop and no new physical loss. The diverted-hold seed21020 timeout at696/700 is retained as a void, not a success. The six P4/sequence failures remain unresolved.

+Physical means use retained episodes only. Wider collection recorded12,973 nonlinear steps; the pilot and remainder cost4,574.583s and4,766.675s. Visible replay recorded14,408 known steps plus one unknown supervisor-timeout count, taking5,400.987s. These evaluations add no training updates. Source step counts for inherited fits overlap and must not be summed as fresh experience.
+
+The complete inference implementation, numeric resources, detailed README and provenance are
+bundled in `checkpoint.zip`. The resident launcher extracts one opened archive into a temporary
+directory, runs it, and removes that directory on normal shutdown. No pre-existing external
+checkpoint or files are required. This packaging adds startup work only; the 2 kHz control loop
+is unchanged. Future publication atomically replaces this one checkpoint file, so a running
+or newly starting process always uses one complete parameter set.
