A key on a set, and the swap that waits for the fight

Phase 4 of 01M1Y4JDFMVHEB87QK9R1KP4BJ, the equipment manager. The part that gets pressed forty times a night.

What lands

A key per set. The chip on the character page shows what it is bound to, and the key is taken and handed back the way the addon already takes a key everywhere else.

There is a card open about that: taking a key off the client is written eight times in this tree. This is the ninth, so it either uses whatever that card lands or it is written to be the ninth caller of it. Do not write a tenth private copy.

No secure button. Nothing in a gear swap is protected, so the key runs plain Lua, and the ten buttons at login that killed the weapon loadouts do not come back.

The swap that waits

Press it in a fight and the hands go on immediately, because slots 16, 17 and 18 are the three combat allows. The rest is held and finished on PLAYER_REGEN_ENABLED, and the line says so:

put on prot: shield on, 9 pieces waiting for the fight to end

Refusing would be the wrong answer. A shield press mid pull is exactly when you want this, and the queue from phase 1 already exists, so the wait is a state on the queue rather than a second mechanism.

A second press while a swap is waiting replaces the wait rather than queueing behind it. Two sets half applied is the worst outcome available here.

Testing it in game

Bind a key to a tanking set. Press it standing still and watch the whole thing go on. Pull something, press it, watch the shield land and the rest wait, then let the fight end and watch it finish. Press two different sets mid fight and confirm the second one wins outright.

The gate

Extends 88-gear-sets.lua. The combat split plans the hands and defers the rest, the deferred half runs on regen enabled, and a second apply replaces a waiting one instead of stacking.
