# EmberScope source-derived review package

- Source design: `emberscope-starter-freeform-v1`
- Source revision: `2026-06-09`
- Source hash: `1fef0451d621f2d117af4200fc60abd90b62ad6310e727c4e2d271988fe83961`
- Overall status: `screening_possible_not_prototype_ready`

This package is generated from the committed component-level source spec.
It preserves the legacy review-package paths for stakeholders while
making the source JSON, validation gates, CAD, Blender geometry, layout,
current-design parameters, and prescription traceable to one hash.

## Automated gates

| Gate | Status | Measured | Limit |
| --- | --- | --- | --- |

| edge_throughput | pass | 0.383721 | 0.3 |
| focus_plane_consistency | pass | `{"center_error_um": 0.0, "normal_angle_deg": 0.0, "passes": true, "sensor_rms_um": 6485.040396983787}` | `{"center_error_um": 0.001, "normal_angle_deg": 0.0001}` |
| freeform_departure_screen | pass | 9050.88 | 10000 |
| prototype_edge_rms | fail | 4524.28 | 34 |
| detector_energy_gate | not_evaluated | - | 0.5 |

## Files

- `source-design.json`: exact source spec copy used by this package.
- `validation.json`: automated gate report and test plan.
- `layout.svg`: component layout generated from the source spec.
- `cad.scad`: OpenSCAD CAD handoff generated from the source spec.
- `starter-freeform-blender-geometry.json`: Blender-format geometry payload.
- `starter-freeform-blender-scene.py`: runnable Blender scene renderer.
- `current-design/starter_freeform_parameters.json`: source-derived current-design metrics.
- `current-design/starter_freeform_prescription.json`: source-derived mirror prescription.
- `mirror-shape-metrics.csv`: compact source-derived metric row for spreadsheet review.

## Open caveats

- The current surface set remains a starter shape demonstration rather than a fabrication-ready prescription.
- The detector-energy gate is not yet closed from this source spec; edge RMS remains hundreds of detector pixels.
- The baffle, window, electronics, and bench components are package allowances, not detailed mechanical drawings.
