Summary

  • avoid creating a Messages UI entry while a custom dealer relationship is locked
  • create and reveal the dealer conversation when the relationship unlocks
  • hide legacy empty locked-dealer entries created by older S1API builds without hiding conversations that contain messages or responses
  • remove the relationship hook during NPC cleanup
  • add dealer conversation lifecycle policy coverage

Root cause

NPCDealer.EnsureDealerCategory() called NPC.SetConversationCategory(...) with ensureUi: true unconditionally. Categorizing a locked custom dealer therefore called MSGConversation.EnsureUIExists() and inserted an empty thread into the Messages app before the player had discovered the dealer.

Compatibility

  • unlocked and saved dealer conversations keep their existing visibility state
  • a real incoming message can still create and reveal a conversation before relationship unlock
  • older empty locked-dealer entries are hidden after load
  • Mono and IL2CPP use the same policy and the existing relationship event bridge

Validation

  • MonoMelon: 600/600 tests passed
  • Il2CppMelon: 589/589 tests passed
  • git diff --check

Closes #269

Dealer conversation lifecycle

Layer / File(s) Summary
Locked conversation visibility policy
S1API/Entities/NPCDealer.cs, S1API.Tests/Entities/DealerLifecyclePolicyTests.cs
NPCDealer creates conversation UI only for unlocked relationships and hides locked conversations only when they are rendered and empty. Tests cover both policies.
Unlock transition and lifecycle cleanup
S1API/Entities/NPCDealer.cs, S1API/Entities/NPC.cs
Relationship unlocks make the dealer conversation known and visible, ensure its UI, and refresh its badge. Runtime cleanup unsubscribes the unlock handler and cleans up dealer hooks.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 6aba7

The change limits locked dealer conversations from appearing in Messages while preserving existing unlocked and message-backed conversations. No actionable merge-blocking risk remains after normal checks and review.

In `@S1API.Tests/Entities/DealerLifecyclePolicyTests.cs`:
- Around line 58-94: Add focused lifecycle contract tests for NPCDealer covering
persisted save/load hiding, UI creation when a relationship unlocks, visibility
of incoming messages before unlock, and cleanup or deregistration of the unlock
handler; execute these tests against both runtime targets while preserving
legacy persistence and multiplayer restoration behavior.

In `@S1API/Entities/NPCDealer.cs`:
- Line 150: Make TryHookConversationUIRefresh idempotent by tracking the
currently hooked MSGConversation instance and installing
onLoaded/onConversationOpened wrappers only once for that instance. Reset the
tracked instance when a new conversation replaces it, while preserving refresh
behavior for the new conversation and all callers through EnsureDealer().
