One connected research chain — not a demo pile.
From transparent physics, to detector evidence, to energy-conversion modelling, to independently reviewable research objects. Every calculation returns one universal run envelope with identity, warnings and lineage; every claim links to its inputs, model version and reviewer state.

The products
FusionSim
Transparent p-¹¹B physics engine (cross-sections, reactivity, bremsstrahlung, L0–L2).
Open FusionSim →AlphaTrack AI
Detector-image evidence: calibrated counts, morphology, human review, uncertainty.
Try synthetic demo Model cardDirectConvert
Spectrum-aware charged-particle energy conversion: ideal (L0) and loss-aware (L1) stages, exact energy ledger, optimizer, uncertainty. Model, not machine.
Run in browser Model cardResearch Hub
System of record: projects, sources, equations, datasets, runs, releases and provenance.

✓ Technical verification (internal, done)
- Canonical hashing is byte-identical across Python and JavaScript.
- DirectConvert energy conservation to machine precision (DC-VAL-01).
- Optimizer cross-checked against brute force; η = n/(n+1) literature case.
- AlphaTrack plate-level splits with no tile leakage; deterministic runs.
- Reproducibility: regenerate-from-export matches; tampering is detected.
These confirm the software computes what it claims — not that the physics matches reality.
◷ Scientific validation (required, pending)
- Real CR-39 benchmark with blinded experts and inter-rater study.
- Detector-specific calibration and partner-lab protocols.
- Independent trajectory-code comparison for DC-L2.
- Reviewed, unit-checked field maps for trajectory studies.
- External specialist review before any released performance claim.
These are required before any real-world performance or physical claim.
