Step 1 of 10 in the C344–C353 authorization.\n\n**Both primary598 gaps have two exact, source-admitted600 realizations. The source’s own worked example corresponds to holding the Flood and selecting the higher Noah state.**\n\n| Primary path | Original MT Noah→Flood | Hold Flood: select Noah | Hold Noah: select Flood |\n|---|---|---|---|\n| i3 | 3246→2648 =598 | **3248→2648 =600** | **3246→2646 =600** |\n| i5 | 3248→2650 =598 | **3250→2650 =600** | **3248→2648 =600** |\n\nMT is restored CainanON/Terah60/full430 throughout. Each output is a same-Gear Noah/Flood pair. The first column of repairs raises Noah by2; the second lowers Flood by2. All endpoints already occur in C286.\n\nFile_02 §§6.2–6.3 holds Flood2243 and compares Noah2841/2843. Adding the existing215+60+130 context displacement places that local example at2648 and3246/3248. The alternate held-Noah repair is supported by the separate ordinary Flood Gear register; it is not the held-Flood example printed in File_02.\n\nThe companion input is599, because the actual MT Noah is paired with Flood close. Its product is **601+1/299**, not601. Neither held-endpoint requirement matches an admitted MT source endpoint. No MT companion or fractional source endpoint is introduced.\n\nThis establishes local gap-to-source correspondence, not an operation on an entire chronology. The next question is whether the two repairs exhaust the admitted600 alternatives and which parts of the529 structure each retains.\n\n## Verification and limits\n\n18 main checks and 17 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.\n\nSource gap conversion, not whole-date scaling or ResidueProtocol. No new endpoint or MT person companion.\n\nMirror/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.\n\n## Decision after this result\n\n**C345, proposed and unexecuted:** Enumerate all same-context MT600 Noah/Flood pairs across the three admitted Gears for the two primary SP comparison paths. Determine exactly which preserve2K and which preserve the460/490 Noah-death partition.\n\nTwo held-endpoint repairs are established. Completing the tiny three-Gear domain will show whether another admitted repair can preserve both structures at once.\n", "evidenceLinks": [{"id": "d-24203a4c3b282f9b", "title": "File 02"}]}
