490d C367 — Fixed19K native Noah lifespan transport

24 September 2026. Step 4 of 10 in the C364–C373 authorization.

The existing19K span transports the entire native cumulative Noah950 interval to the retained reflected SP Noah950 interval. It works on all four complete C287 rows, including both SP rails, with the original same-phase ancestry.

At i3, −7295+10051=2756 and −6345+10051=3706. Cumulative Noah birth maps to reflected SP Noah death; the cumulative Noah-death/Shem-birth seam maps to reflected SP Noah birth. The950 width is retained. Endpoint event roles remain explicit; the translation preserves coordinate orientation while exchanging birth/death roles.

The19K value is already the C287 long cross-span. No axis or translation constant is fitted. Across16 source/target phase choices, the eight same-offset components pass exactly. This differs from C366’s interval reversal, which required opposite offsets.

The success does not include the OFF-Noah internal vertex. Let k=i+2 and e mark the SP companion. Sending an existing OFF-Noah annual member j to the restored-MT Noah birth would require j=k+30+e, outside0…7. All32 available internal-member tests fail. If one uses C366’s matching reversal member j=k−e, the translated image is30 years below the regular target on primary rows and32 below on companion rows. For example,−6835+10051=3216 rather than3246.

Thus the fixed19K comparison transports the complete native lifespan endpoints, while its internal Cainan partition has a different orientation. The source role connection is real but shares the inherited950 and19K values; it is not an independent determination of them.

Verification and limits

54 main checks and 16 frozen-input/predecessor authentication checks passed. A second main replay produced byte-identical DATA/RESULTS. These checks and the source interpretation were performed by the root agent; no new independent-agent review is claimed. All frozen originals and standing controls remain unchanged. Verification counts are not independent-witness counts.

The endpoint transport reverses event roles and does not transport the full Cainan partition. Shared constants and phase repetitions are not independent witnesses.

Mirror/529 focus: K=529, E=25/23, P=70/69. Global paired Mirror January AD1; local junction January AD2; no civil year zero. Regular Gears are Noah/Shem/Flood only. SP minus-one person companions remain local to SP Noah/Shem; Flood close is a separate boundary. No upstream/cumulative Gear, new endpoint or phase, fitted anchor, global axis, primer reopening, canonical or graph edit. Capture now; canonize later. Source identity, context, modal binding, generated coordinates and phase ancestry stay distinct.

Decision after this result

C368, proposed and unexecuted: Apply the fixed19K whole-Noah criterion to all20 C319 controls and compare it with the regular joined-map criterion from C360. Determine what each condition selects and whether their conjunction adds any independent source prescription.

The fixed transport gives a source interpretation of the long cross-span. The held control menu can now distinguish its cumulative selection from the regular-side selection.
