Ordinary income cancellation, retained low effects, occupied percentage income and immediate ally sharing must compose from their own rules; the current unoccupied branch is not authority for a future occupied Karama outcome.
 
+### Guild Nexus Betrayal is a full-fee exception
+
+The [original Guild Nexus face and bounded payment contract](NEXUS_GUILD_RULES.md#nexus-guild-betrayal) expressly take one whole shipment payment, including one's own, and override occupied Junction income. For an accepted use, preserve the original **charged total**, not only this document's eligible `gross` or `ceil(gross / 2)`: the holder receives all of that fee once, and ordinary Guild/bank/occupier settlement for this invoice is suppressed. A four-spice fee yields four to the holder, not two plus two to an occupier. The original payer and authorized escrow still fund it once before any own-payment refund; future receipt is not upfront funding.
+
+This exception does not resolve ordinary two-odd-contributor rounding, occupation owner/expiry or retained penalties. All-pass/no-use settlement retains its native routing and guards; no hypothetical card play may admit an otherwise unresolved ordinary invoice. Free or stopped transport has no positive fee to redirect. The explicit fresh classic/Guild/Nexus profile uses genuinely seeded Homeworld custody and existing legal shipment/Junction adapters; it grants no new route or sponsorship. Its [direct bounded local verification](NEXUS_GUILD_RULES.md#verification-and-release-boundary) includes full occupied low-Junction fees, independently of this document's historical unoccupied-income evidence and broader Homeworld gates.

 ## Required verification before a runtime claim
 
 Meaningful regressions cover odd/even and zero receipts, rejection of two eligible odd contributions before declaration or payment, coincident 2 + 1 rounding, both contributor identities, protected original contribution evidence, module-off parity, current 4-to-5 and 5-to-4 changes across legal Ghola interruptions, cancellation without refund, all listed Emperor sources, all admitted shipment adapters and exact parent restoration. Save/recovery tests should prove no repeat debit, card acquisition, force move or faction credit, and reject altered gross/source/owner binding without persistence. Public previews may show the current numeric split but must not expose the purchased card's private face.
