Resolve advisor conversion after Gamont before final victory

Commit original Gamont use/return or empty revelation before its separate mandatory-conversion counter. Preserve private fuel provenance beside a public phase8 receipt, retain legacy phase5 sources and defer the genuine final chooser through both direct and Semuta cost completion. Consume the parent once; ordinary Mentat gains no chooser and victory waits for original confirmation. Existing provisional continuously-alone duration remains.

Validation: 18 files277/277, types/lint/build, five native Gamont/response/GameTable SSR journeys and eight existing-profile paths. Genuine52/56-action public Advanced sources earn a real third-stronghold win versus prevented next-turn outcome. Empty revelation remains pure-source proof; full combinations/remaining producers, browser/deployed and final assurance stay open. No saved-room/D1/restart/deployment operation or AI refinement.

+## Advisor conversion after Trip to Gamont — 24 October 2026
+
+Compose supplied physical29 B’s Mentat return with physical17’s group counter and
+physical28 E’s mandatory alone conversion. Complete original Gamont cost/disposal,
+return/revelation first; prevent only the resulting conversion before victory.
+Do not require an actual returned counter: a revealed empty No-Field can also
+remove the last foreign presence. Preserve the same provisional continuously-alone
+hold. Public phase8 evidence omits card/Nexus fuel identity; private provenance
+stays in its parent. Both original direct and Semuta continuations defer the
+final chooser until that parent is consumed. Ordinary Mentat gets no final
+chooser, and the callback itself never declares victory.
