Preserve Homeworld and Junction transfers through advisor conversion

Capture surviving alone BG groups after committed native board-to-world and
Junction board transfers. Keep typed payment/custody and shipment use, private
original declaration snapshots and one original Junction arrival. Preserve
Junction immunity independently of the BG conversion counter.

Validation: 18 affected files218/218, types/lint/build, nine native transport
and GameTable SSR journeys, sixteen existing-profile response paths. Genuine
37/38/42/36-action sources earn original routes and costs3/5/10/1. Rename two
fixture variables rejected by lint without changing rule validation. Broader
combinations/full modes remain unfinished. Not deployed; no saved-room/D1,
reset or restart operation. Runtime fingerprint

+## Advisor conversion after Homeworld transport — 24 October 2026
+
+Extend the existing physical17/28 E composition to native Guild board-to-world
+and board-origin Junction transfers. Capture surviving alone groups only after
+the typed transfer, preserving original interception/privilege/rate, payment,
+custody, shipment use and income. Junction's own Homeworld permission/tariff
+immunity does not make the separate BG conversion advantage immune. Keep the
+existing provisional continuously-alone duration. A fresh public UUID/physical
+receipt omits the private original declaration snapshot. Consume the private
+parent before resuming a Junction board arrival once; world destinations have
+no arrival. No original pre-transfer eligibility is rerun after commitment.
