Added the 13-field trace pattern and measured flat-sensor acceptance quantities needed for survey optimization.
Internal engineering log
Engineering log (internal voice)
This is the project's raw day-by-day engineering notebook, published for traceability. Entries use internal task IDs and optical-design shorthand, and are not edited for outside readers. For the reviewer-facing state of the project, start at the overview or the evidence summary.

2026-06-20 - EmberScope daily work
Converted the COTS branch into a quote-ready evidence packet.
2026-06-19 - EmberScope daily work
Mapped RFS-011 answer patterns to closeout and next-action readiness.
2026-06-18 - EmberScope daily work
Turned RFS-011 closeout asks into a stakeholder answer pack.
2026-06-17 - EmberScope daily work
Separated locked requirements from remaining RFS stakeholder asks.
2026-06-16 - EmberScope daily work
Added a COTS payload screen for the RFS-011 fleet decision.
2026-06-15 - EmberScope daily work
Added a coverage-area sizing grid for the RFS-011 mission decision.
2026-06-14 - EmberScope daily work
Built the F-number / aperture trade study that resolves the binding open item on the four-mirror prescription, adding the NETD~F#^2 and PSF energy-concentration physics the committed radiometry model omitted; the headline finding is that the F/5 worry is regime-dependent and the committed 200 mm plate scale is a spotter, not a survey camera.
2026-06-13 - EmberScope daily work
Found and fixed two ray-tracer math errors (conic sag-gradient factor, OPD reference surface) via new analytic regression tests; re-evaluated the design of record and all multi-mirror screening artifacts; overhauled project hygiene (uv migration, ruff/mypy, CI test workflow).
2026-06-11 - EmberScope daily work
Added the RFS-028 beam-obstruction gate to the multi-mirror checkpoint; reworked the public site for reviewer clarity; exported geometry artifacts and renders for the optimized prescription.
2026-06-10 - EmberScope daily work
Published mission-survey storyboard handoff; first unobscured optimized four-mirror prescription.
