# C294 — Fixed-reflection closure in the full source fields

24 September2026. The common annual-offset restriction of C293 is removed; both bridges remain fixed.

**One complete source-qualified arrangement closes the fixed8K reflection:527,1587,2645,3705. Its gaps are1060,1058,1060.** It uses the opening member of each cumulative field and valid regular endpoints, but it is not an all-K subdivision.

The two full eight-member source fields are cumulative LXX ON Shem6350–6343 BC and OFF Flood5290–5283 BC. Translate each source by13K=6877, then apply the fixed reflection J(y)=4232−y. The required regular counterpart is compared with the528 qualified endpoint records, preserving Noah-birth or Flood-boundary role. Sixteen source requirements give8448 source/target comparisons.

Exactly two requirements have matching records:

|Cumulative source|13K landing|Required counterpart|Source identity|
|---|---:|---:|---|
|LXX ON Shem opening6350 BC|527|3705|SP G1 companion Noah birth, OFF/full430/Terah0|
|LXX OFF Flood opening5290 BC|1587|2645|MT G1 Flood close, ON/full430/Terah+60|

The inner sum1587+2645 and outer sum527+3705 both equal4232. Reflection reverses the physical ±1/4 component order exactly. No new date, Gear, bridge or comparison axis is chosen.

Relative to the previous odd-K arrangement, the outer points are K−2 and7K+2, while the inner points remain3K and5K. Thus the outer spacings are2K+2=1060 and the central spacing2K=1058. This is symmetric about the fixed4K comparison center, although it is not equally spaced.

The raw cumulative source difference6350−5290=1060 is also2K+2. The regular counterpart difference3705−2645=1060 agrees. Their matching cross-Mirror widths are8995=17K+2; the outer total is10055=19K+4. The lower cross-width remains7935=15K. These deviations are retained rather than rounded into K multiples.

This positive result does not contradict C293: that step held one common annual offset, while the present exact outer pairing uses the Shem opening before the six selected Shem indices2–7. It also does not contradict C284/C285: the first leg fails their all-K requirement. Different explicit conditions select different source configurations.

Eight mathematical/domain checks and seven authentication checks pass; exact replay agrees. All fourteen failed source requirements remain in the evidence. Author review only; no canonical amendment.

**Best next bounded step — C295:** derive the exact compatibility conditions for fixed8K reflection and the all-K subdivision. Determine whether both can coexist in the admitted source domain, and record the minimal formal bridge adjustments without adopting them. High is sufficient.
