Row 2003 (b144 option C): the second pendant slot, client and server.

Server

• New table extra_pendant_slots (character_id, open_until). characters is at Diesel's 32-column limit, so this is a separate table. Player.extra_pendant is loaded and saved with the character.
• Equipped position -51 (PENDANT2) takes pendants. item_move refuses moves into it unless the slot is open.
• Once the slot runs out, a pendant worn at -51 stays on but stops counting toward stats (Player::worn_equips), as v83's BasicStat::SetFrom (0x77ec9f) skips slot 51 past its expiry. HC's recalc_stats does the same.
• The character data carries the slot's expiry as the FILETIME after the five slot-limit bytes (1900 = shut). 121 (0x79) is sent after CHAR_INFO, so the client builds the wide Equip window.
• Cash Shop:
  • SET_CASH_SHOP now sends the changed-commodity list, adding SN 50200172 (5550000, 2,000 NX, 30 days, on sale).
  • Buy mode 9 charges NX Credit or Maple Points and extends the slot by Item.nx addDay from the later of now and the current expiry. It replies with CASHSHOP_OPERATION 0x66 (u16 0, u16 days).

HeavenClient

• Parses the expiry, the changed commodities (by flag, in v83 order), 0x66 and 121.
• The wide Equip window gets a PENDANT cell at (3,3), shown red while the slot is shut.
• Tooltips:
  • a worn PENDANT2 item shows 0x144a/0x144b;
  • 555 items show 0x145b/0x145c.
• The Cash Shop asks the 0x1458 question and sends the buy, then shows the 0x145a/0x1459 notice. v83's year-first date order is kept.

Tests (full suite passed: 306 passed, 0 failed)

• Harness: cash_shop_pendant_slot, plus updated cash_shop and change_channel.
• Unit: an item_move gate test and an expired-slot stats test.
• Client: item_expiry and cash_catalog tests.

GUI-checked on the lane stack:

• The red cell, then the buy (8,000 NX left).
• "You have added PENDANT slots.", then the extension notice on a second buy.
• The cell unlocked, the second pendant equipped at -51 (in the DB), and its expiry tooltip.

Deviations and picks are noted in v83ref QUESTIONS (2026-10-25, row 2003).
