Step 9 of 10, C435–C444.\n\nThe original fixed Mirror exchanges **do not carry the new3188 profile or its two-E paths into the retained cumulative register**. A smaller four-year Gear pair does have a sourced cumulative image and is preserved separately.\n\nThe exchanges are unchanged: `X(x)=−2639−x` and `X(x)=−2635−x`. The original C287 i3/i5 corners are positive controls:3706/2648 maps to−6345/−5287, and3708/2650 maps to−6343/−5285. Both retain the8993=17K cross-spans.\n\nThe cumulative membership test uses the authenticated **48-record LXX Noah/Shem/Flood register from C365**, including native Cainan ON and theoretical OFF annual positions. It is not a census of every cumulative date in every repository file. No regular Gear is applied to cumulative states.\n\nFor each exchange, all208 source-domain memberships of the four local reflections were tested:416 trials in total. There are37 sourced slot images. Of212 coordinate-orbit/exchange comparisons, only five retain both ends, and four are fixed-center images.\n\nThe sole nonfixed image is:\n\n| Regular pair | Exchange | Cumulative image |\n|---|---|---|\n|MT Noah3246 /3250 (G1/G3)|−2639−x|LXX-OFF Shem−5885 /−5889 (annual indices5/1)|\n\nIts center3248 maps to−5887 (annual index3). This is a four-year interval preserved by reflection, not a new529 multiple or permission to transport regular Gears into cumulative chronology. Under the second exchange, one required end falls outside the retained annual field.\n\nIn contrast, none of the16 exchange trials for the core/profile coordinates3620,3206,3188,3170,2756 and path stations2148,2020,1956 has a sourced cumulative image. Thus the new full five-point profile and both two-E paths fail the fixed-corner integration test in this domain.\n\nThe formal relation `X R_c X = R_(A−c)` holds for exchange constant A, but algebra does not supply the absent cumulative centers or endpoints. Centers3188/3190 have absent images under both exchanges;3248/3250 have some sourced images, as the small positive result shows.\n\nThis preserves both findings: a useful local source grammar and a sharply bounded connection to the inherited Mirror. No new exchange, global axis, phase or cumulative source is fitted.\n\n## Verification and scope\n\n428 calculation checks and 23 source/predecessor authentication checks passed. Main result files replay byte for byte. These are root-agent checks, not an independent-agent review or independent historical witnesses.\n\nNegative claims are restricted to the unchanged corner exchanges and48-record LXX cumulative menu. The sourced four-year partial image is retained; it does not close the core profile or establish a new17K rectangle.\n\nMirror/529 focus: K=529, E=25/23, P=70/69; J=300/299 remains File02 gap conversion, not a calendar date operator or Residue Protocol. Regular Gears are Noah/Shem/Flood only. SP person companions are local to Noah/Shem; Flood close is an independent event boundary. Both500/100 and502/98 bindings remain valid; SP primary Noah death retains its inclusive/harmonic qualification. LXX native Cainan is ON; OFF is theoretical removal. Global paired Mirror January AD1; local junction January AD2; no civil year zero. No new source point, phase, fitted axis, upstream/cumulative Gear, primer reopening or canonical/graph edit. Capture now; canonize later. Coordinates, source labels, context aliases and derived comparisons remain distinct. Counts are not independent historical witnesses.\n\n## Best next bounded step\n\n**C444, proposed and unexecuted:** Consolidate C435–C443, verify the decisive source grammar and operator/Mirror boundaries with a separate implementation, audit all sealed packets, and publish C444 with the reading index and recovery packages. Leave C445 unexecuted.\n\nThe source census, reduced reflection grammar and E/Mirror limits now form a coherent bounded result. The final authorized step should authenticate and preserve it before another comparison family is opened.\n", "evidenceLinks": [{"id": "d-24203a4c3b282f9b", "title": "File 02"}]}
