490d Mirror checkpoint after C265
23 September 2026. Latest completed step: C265. Continues C205; this is not a recovery restart.
All sixty authorized steps C206–C265 are complete. The six endpoint routes, their 191-year center offset and their δ=2 /1060 squares are integrated. Peleg-number contacts remain arithmetic associations without a new incident event path.
K=529 and r=25/23. BC base B means (B+1)t/Bn BC; reflected AD base A means AD At/(A+1)n. Their civil span is B+A in both seasonal components, with no year zero. Signed paired centers are −B and +A; the center model uses components ±1/4 and restores this separation after dilation. An interval center is geometry, not an event or a proposed universal Mirror axis.
Regular Gears are restricted to Noah/Shem/Flood. Creation and Conquest retain fixed source-field members; no fourth Gear is admitted. Generated coordinates, source-field membership and stored graph incidence are distinct. File_18/File_09 and the frozen C127 graph are unchanged. Earlier N01/N03 qualifications, the missing Shem join, closed primers and unestablished original Reports 11–25 remain unchanged. This packet selectively uses prior evidence; it does not rerun completed campaigns. Assertions and alternative placements are not independent historical witness counts.
Verification through this checkpoint: 727 step-specific checks plus 1140 repeated frozen-input checks. Every ten-step block has an isolated byte-identical replay. Every certificate points to its predecessor by SHA256.
| Step | Bounded result |
|---|---|
| C206 | Two fixed Creation anchors and their interval centers |
| C207 | Half-width gains of 299 and 325 |
| C208 | The center curvature is half the inherited 52 |
| C209 | The two right-endpoint midpoints have unequal source status |
| C210 | Expansion of the two halves around the named death |
| C211 | Holding the cumulative left boundary instead of Creation |
| C212 | The fixed SP 17-fold center crosses the 13-fold centers |
| C213 | The MT 17-fold center supplies a second fixed reference |
| C214 | Two anchored maps related by a two-year translation |
| C215 | Uniqueness and scope of the Creation-anchored map |
| C216 | A finite audit of the anchored map on named coordinates |
| C217 | The generated midpoint remains outside all retained Noah-death rails |
| C218 | Expansion intertwines 598 and 650 translations |
| C219 | A fixed 650 translation does not commute with expansion |
| C220 | The next iterate leaves the annual endpoint lattice |
| C221 | The retained 598–52–598 source rectangle |
| C222 | The expanded rectangle preserves lengths but loses source support |
| C223 | The midpoint carrier 552→600 belongs to the same ladder |
| C224 | Center dilation and seasonal-pair restoration |
| C225 | Admission boundary for the local expansion maps |
| C226 | Centers of the cumulative 17-fold expansion |
| C227 | Holding Creation while the macro Noah endpoint moves |
| C228 | The 868 prefix becomes center gaps 434→664→914 |
| C229 | The 7-and-10 split explains both macro width and center drift |
| C230 | Proportional Creation movement preserves a scaled prefix |
| C231 | Three anchor choices agree only at the original attachment |
| C232 | The local and macro maps differ by their fixed anchor |
| C233 | Integral expanded square vertices do not preserve ordinary Creation |
| C234 | Fractional endpoint parts cancel in the 13-fold width |
| C235 | Keep the local stage and macro stage separate |
| C236 | Global reflection gives a right-anchored dual ladder |
| C237 | The 8×529 complement yields generated dual anchors |
| C238 | Reflection reverses the order of the fixed center partition |
| C239 | The fixed native 11-fold prefix inside all three 13-fold intervals |
| C240 | The 1656 tail and the MT antediluvian span have distinct endpoints |
| C241 | The first expanded 11-fold endpoints are generated |
| C242 | The second 11-fold expansion reaches the preceding MT Flood Gear |
| C243 | The 6875 interval center is one year earlier than the 6877 center |
| C244 | The two families create a 529→575→625 center-separation ladder |
| C245 | Endpoint recovery in the coupled 11- and 13-fold construction |
| C246 | All seven native 11-fold pairs yield six sourced final endpoints |
| C247 | No intermediate endpoint matches the held Noah/Shem/Flood register |
| C248 | P6 gains a sourced 6875 close endpoint without repairing its 6877 gap |
| C249 | The sixth row supports a final Flood endpoint but lacks the old cumulative start |
| C250 | The closing member and full-week residual remain excluded |
| C251 | A shifted apparent anchor does not preserve the native endpoint result |
| C252 | The source Conquest-to-Flood tail is 1056, not 1058 |
| C253 | The final 1250 interval has same-Gear Noah/Flood endpoints |
| C254 | Six source-qualified 17-fold routes with a new internal subdivision |
| C255 | The 8-fold preimage makes the residual redistribution explicit |
| C256 | The double-11 selector chooses same-Gear rather than next-Gear Flood |
| C257 | N04 and the P6 double-11 interval share a center with different endpoints |
| C258 | The selected 6875 interval lies 191 years before the SP 17-fold center |
| C259 | The same six selections realize the inherited δ=2 square |
| C260 | P6 start and close cases remain two different residual states |
| C261 | Two Peleg-number contacts exposed by the 6875 selection |
| C262 | The Peleg contacts do not supply a new contiguous event path |
| C263 | A minimal dependency description of the coupled families |
| C264 | Completion inventory with source and generated statuses separated |
| C265 | Sixty-step synthesis and verified stopping point |
The authorized batch ends at C265. Best next bounded step C266: check the seven generated intermediate centers 1905–1911 against a finite fixed post-Flood MT event register, distinguishing numerical contact from endpoint identity and adding no regular Gears. C266 is proposed, not executed.
