 - Added immediate durable opt-in persistence, join-time restoration, and quiet infinite Resistance reconciliation.
 - Leaf tracks its live Resistance fingerprint and conservatively preserves a visibly distinct Resistance effect.

+- Added configurable, color-compatible prefixes to standard chat display names and player-list names.
+- Added conservative main-scoreboard team prefixes for overhead names without displacing unrelated teams.
+- Name cleanup restores only values Leaf installed; third-party changes are preserved.
+- Documented scoreboard, custom chat, tab-list, and per-viewer scoreboard limitations.
+- US-003 remains in progress until combat and global administration paths are verified.

 ## Acceptance criteria
 
-- [ ] An actively protected player has a configurable leaf prefix before their name in the player list.
-- [ ] An actively protected player has the same prefix before their overhead name where Spigot supports it.
-- [ ] An actively protected player has the same prefix in standard Spigot chat where the active chat format supports it.
-- [ ] The default prefix uses a leaf symbol with readable spacing and Minecraft-compatible formatting.

 - [ ] The prefix is removed immediately when the player opts out or is opted out by PvP or an administrator.
 - [ ] Prefixes are suppressed while Leaf is globally disabled and restored for online opted-in players when it is re-enabled.
-- [ ] Prefix updates do not overwrite unrelated display-name text where the Spigot API allows the values to coexist.
-- [ ] Scoreboard-team and third-party chat-plugin compatibility limitations are documented, and unsupported integrations fail without affecting protection state.
