Selection policy
Hard gates precede comparative preferences.
- Reject every candidate that fails any declared hard gate.
- Within the passing pool, prefer lower manufacturing-risk score.
- Then prefer lower rough fabrication-cost estimate.
- Use mirror-count diversity only within the hard-gate passing pool.
The manufacturing score and rough fabrication-cost estimate use the repository's existing screening model with the declared Al_lightweighted assumption. They are not vendor quotes and cannot rescue a failed optical or package gate.
This gate records the measured three- through seven-mirror families plus the bounded RFS-079 throughput-first TMA refinement, RFS-080 fixed-geometry freeform correction, RFS-081 fixed-fold power/freeform correction, RFS-082 local fold/power/freeform correction, RFS-083 flat-detector tilt correction, RFS-084 fixed-tilt freeform refit, RFS-085 post-freeform detector-tilt refit, RFS-086 coupled detector-pose trade, RFS-087 coupled mirror-surface/detector-pose correction, RFS-088 fixed-surface/pose freeform refit, RFS-089 strict reserved-pupil clearance recovery, RFS-090 clearance-guarded freeform refit, RFS-091 clearance-guarded power/conic/focus correction, RFS-092 post-power clearance-guarded freeform refit, RFS-093 coupled geometry/power/focus correction, RFS-094 strict-clearance tilt-coupled correction, RFS-095 independent-start clearance probe, and RFS-096 coarse strict-clearance paraboloid start, with their configured optimization budgets. It is not a general infeasibility result for all reflective architectures.
RFS-096 provides a coarse three-paraboloid prescription start with zero freeforms, an untilted flat detector, 221/221 reserved rays, and a passing 104.1 mm acceptance EFL. Its 3937.7 um worst RMS and 16439.8 um flat-focus spread fail. Apply bounded optical-error correction while guarding all 221 reserved rays.
