IX-StellaratorForge v0.10.0: SFR-5 Reality Gradient

[BryceWDesign]

Title:
IX-StellaratorForge v0.10.0

Adds SFR-5 Reality Gradient, an adaptive inverse-design and architecture-rejection layer built from the v0.9.0 SFR-4 magnetic campaign.

Primary result

The SFR-4 magnetic family remains rejected:

• 80 direct-filament coil configurations evaluated
• 0 configurations passed the combined topology screen
• 3.826523x transform increase required to reach the minimum iota gate
• 3.887363% normalized excursion margin remaining
• held-out normal-field error remains 12.982550x above its declared limit

SFR-5 therefore does not spend additional computational budget brute-forcing the same fixed helical family.

Instead, the next inverse-design search opens additional degrees of freedom across:

• plasma boundary
• winding surface
• nonplanar coil geometry
• coil currents
• magnet engineering constraints

Added in v0.10.0

• Reality Gradient constraint-pressure framework
• adaptive architecture-family search
• rejected-family evidence memory and fingerprints
• SFR-4 magnetic autopsy derived from committed evidence
• movable-geometry contracts
• external-solver promotion contract
• SFR-5 configuration and schema
• reproducible SFR-5 JSON and Markdown results
• SFR-5 provenance and technical basis
• new promotion gates and no-overclaim checks
• release and quality-gate integration
• expanded test suite

Validation

• 122 tests passed
• IX-STELLARATORFORGE quality gate: GREEN
• SFR-5 Reality Gradient invariants: PASS
• SFR-5 no-overclaim campaign: PASS
• Release manifest: PASS
• 315 manifest entries verified against committed Git blobs
• Git diff whitespace check: PASS

Claim boundary

This release does not claim demonstrated finite-beta MHD equilibrium, kinetic confinement, qualified HTS magnets, full 3D TBR, ignition, net-electric fusion, safety qualification, or hardware operation.

SFR-5 earns a stronger search decision, not a stronger fusion claim.

Real movable-geometry sensitivities and production plasma/coil co-design remain future promotion requirements.
