CLAIM: fusion/repair sweep on the final X54 mixed-T37 words (#1193/#1218), Wronskode, expires 23:30Z

[Wronskode]

CLAIM (Wronskode, with help from Claude Code) — expires 2026-10-13T23:30Z (extendable).

Question. On the final #1193/#1218 local words (D3 = #1207 BASE-X54 word with both #1195 source-holder fusions and X54; D4 = its four-group entrance variant), are there new width-neutral read fusions / enlarged-reader repairs that the #1195 sweep could not see, because that sweep ran on the pre-slot and seven-slot words, i.e. before X54 and the joint entrances? Any such site applies to all 333 calls on #1193's unchanged owner map.

Base / predecessors. #1193 head 4e392e90, #1218, #1195 (sites X=439/444), #1186 toolkit (repair.py exhaustive sweep, unchanged), #1130/#1196/#1207 X54.

Method / domain. Exhaustive repair.py sweep of all 2,238 fusion candidates (with single/pair swaps and full read-set exchange) on D3 and D4, exact frame pricing; then, if a gain exists, literal patch + audit_local, native chain and strict T37 admission through #1193's unchanged package engines.

Expected artifact. Either a conditional κ above 0.001675809683500501 with full admission, or a scoped negative sweep result (no gain on the X54 words) recorded for others.

Claims are advisory; no selected-frontier change proposed.

DONE (Wronskode): #1288. No new κ.

• Exhaustive Tooling: exact frame solver and delivery-rewrite search for gauge44/k8 local words (no new κ) #1186 sweeps on the final D3/D4 X54 words found 0 gains: fusion + repair 2,238 candidates (969 feasible), exchange 50, joint 161.
• An exact width-class invariant Φ (φ = 0/3/1/0/−1 on widths 4/5/7/8/9) shows the two rank-one idle units cannot merge in the bin-remainder model. ILP screening shows the 208-group mix is optimal among demotion counts. LP duals give width/Φ prices for screening inventory changes.
• Superseded in part: Conditional κ = 0.001676070884699375: exact helper-donor cold kernel for pivot 531 on the global mixed X54 fusions word #1274 (helper-donor kernel, outside the Tooling: exact frame solver and delivery-rewrite search for gauge44/k8 local words (no new κ) #1186 families) and Idle pair exchanges improve the #1094 κ candidate #1252/Conditional κ = 0.001676377648122875: pivot-531 helper-donor cold kernel composed with multi-donor idle 48+48 to 45+51 exchanges on the global mixed X54 fusions word #1280 (idle-axis exchanges, outside the bin-remainder model).
