Let fighters in body armour keep their helmet free during /pvp start

[XxFran10xX]

What changes

Roleplay choice: people should be able to take their helmets off and on during a fight without worrying about the armour lock.

• /pvp start no longer takes off a helmet that was put on recently. Chestplates, leggings and boots are still taken off as before.
• When the fight is called (after recent armour comes off), each participant still wearing a real chestplate, leggings and boots is recorded on the situation.
• During the fight those players can take their helmet off and put it back on (it still takes the normal helmet fastening time). Everyone else still can't put a helmet on. Removing a helmet was already allowed for everyone.
• Chestplates, leggings and boots stay locked for the whole fight, as before. Dying in the fight still frees everything.
• The helmet rule follows the helmet slot, so masks and heads use the same rule.

PvpSituations.locksArmour now takes the ArmorType, and PvpSituation takes the armoured participants. README and the pvp.yml comment are updated. There are no new config keys or messages.

Tests

• New: ArmourDonningTest.onlyThoseInBodyArmourMayPutAHelmetOnInAFight, PvpCommandTest.helmetsStayFreeForThoseWhoCameInBodyArmour, PvpSituationTest.onlyTheArmouredGetAFreeHelmet.
• pvpStartTakesOffOnlyArmourPutOnRecently now checks that a recent iron helmet stays on.
• All 129 PvP tests pass locally. The full suite's local failures are the known Windows-only ones (locale decimal commas, POSIX permissions).

📝 Summary

Summary by CodeRabbit

• New Features
  • During a PvP fight, players who entered wearing a chestplate, leggings and boots can remove and replace their helmet. Other players cannot equip one.
• Bug Fixes
  • /pvp start removes only recently equipped chestplates, leggings and boots. Helmets and elytra are not removed.

Walkthrough

/pvp start removes recently donned body armour but does not remove helmets. During a fight, participants recorded as wearing a chestplate, leggings, and boots may remove and replace helmets. Other participants cannot equip helmets.

Merge Risk: ⚪ Minimal · up to a893d

No actionable merge-blocking issue is established in the reviewed changes.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 0c32b

The change is confined to fight equipment rules. Body-armour restrictions remain enforced, helmet eligibility is recorded after recent armour removal, and overlapping fights remain restrictive. No introduced security issue was identified in the inspected paths, but compatibility with external plugins remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The affected player scope is the existing same-world selection within the configured radius of the command issuer. Participants are selected from server Player objects and identified by UUID; the command does not accept client-supplied participant identities. This selection logic is unchanged by the PR.

Trust Boundaries and Controls

• observed — Equipment events, deferred right-click swaps and delayed fastening completion use the slot-aware policy. Deferred paths recheck permission at execution rather than relying on an earlier decision. The lock scans every open situation, so eligibility in one fight cannot override another fight that locks the same slot.

Resilience and Maintainability Implications

• observed — Death releases a participant's locks across open situations; closure removes the situation's authority. Quit stops pending fastening without discarding fight membership. These lifecycle responsibilities remain unchanged, and closing a situation repeatedly is harmless.
