**`entity_sound_effect` packet (CB 0x50) field structure:** Confirmed from `minecraft-data/data/pc/1.14/protocol.json` `packet_entity_sound_effect`. Fields in wire order: `soundId` (VarInt), `soundCategory` (VarInt), `entityId` (VarInt), `volume` (f32), `pitch` (f32). Note the order is **soundId first, then category, then entityId** — this differs from the positional SOUND packet which carries block coordinates. Source: `minecraft-data/data/pc/1.14/protocol.json`.
**Villager entity data index 15 added in 1.14.1 (`addIndex(15)`):** ViaVersion `EntityPacketRewriter1_14_1.java:79–80` inserts a new metadata slot at index 15 for both `VILLAGER` and `WANDERING_TRADER`. The slot at index 15 in 1.14.0 was the `VillagerData` struct (type/profession/level, added in 1.14 itself, see `EntityPacketRewriter1_14.java:338–340`); after `addIndex(15)` this shifts to index 16 in 1.14.1. The new slot 15 in 1.14.1 is <!-- UNCONFIRMED: ViaVersion confirms a slot is inserted at index 15 for Villager/WanderingTrader in 1.14.1, but does not name the semantic — likely `villager_xp` (VarInt, total XP earned by the villager, used for level-up UI) based on the 1.14.1 release context, but no primary source (minecraft-data or wiki) in the available refs names this index directly. -->

ViaBackwards `EntityPacketRewriter1_14_1.java:93–96` drops slot 15 entirely when downgrading to 1.14.0 (`cancel(15)`) and remaps slot 16→15 (the VillagerData), confirming no 1.14.0 equivalent exists for slot 15. The new slot 15 in 1.14.1 is <!-- UNCONFIRMED: no available ref (ViaVersion, ViaBackwards, minecraft-data, Velocity, BungeeCord) names the semantic of slot 15 — likely `villager_xp` (VarInt, total XP accumulated by the villager, used for the trade level-up UI introduced in the 1.14.1 patch) given the 1.14.1 changelog context, but no primary source in the available refs names this index directly. -->
