Suggested reviewers: Merge Risk: 🟡 Moderate · up to A failed save can allow a cached shared report to reappear after a restart, even after vassalage ends. Ensure report removal is persisted before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Sharing is restricted to the faction's Spymaster and direct partners, but saved exact reports can survive an unsuccessful cleanup and reappear after restart, including after a retry successfully disables sharing. The exposure is limited to previously shared game intelligence, rather than broader server privileges. Retained concerns

espionage reports for both factions after removing their relation, regardless of

Overlord roll bonus
espionage.vassalage.overlord-offense-bonus(default 25): added to an overlord's margin when its network spies on a vassal, direct or further down the chain.espionage.vassalage.overlord-defense-bonus(default 25): taken from a vassal's margin when it spies on any overlord above it./faction reloadespionage).Sharing with overlord and vassals

special-positions.ymlautomatically, with comments, on first load./faction setrelation, both factions lose today's reports on each other, so nothing shared stays visible. A new vassalage gets the bonus and sharing from the next daily report.allow-sharingoff also hides shared values in reports already cached today. Those fields fall back to the range rolled with the report, when the rolled quality allows them. A shared roster falls back to the rolled sample, and the header line disappears.Testing
