Version 3.0.4 — Sun Haven vault mod (per-character encrypted vault, IMGUI vault + HUD, auto-deposit, shop hooks).
BepInEx/plugins/ (the manager usually creates something like BepInEx/plugins/AzraelGodKing-TheVault/).TheVault.dll and TheVault.Abstractions.dll together—the abstractions assembly must sit next to the main plugin.[The Vault] FullVaultInspector in BepInEx/config/com.azraelgodking.havendevtools.cfg, or Haven Dev Tools (F11) → Azrael's Mods → The Vault.Routine updates aim not to wipe your vault. If a build cannot keep compatibility, maintainers publish a clear warning at the top of the GitHub README, in Thunderstore/Nexus text, the changelog (what to back up), and an in-game / log notice when needed — see TheVault/SAVE_COMPATIBILITY.md in the repo.
Reference TheVault.Abstractions.dll and use TheVault.Modding.VaultModApiBridge.Instance after the vault is ready. Full details: repository README.
