Corrected real errors: several 1.7.x release dates, resource_pack_send version,
config packet ordering, structured-component count (56), PLAYER_LOADED (1.21.4),
entity_sound_effect field order. Confirmed+cited the rest; remaining ~19 items
re-marked UNCONFIRMED (third-party/ViaLegacy/26.2 internals unreachable from refs).

- **`LEVEL_PARTICLES`:** `always_show` boolean field added after `override_limiter`. VV writes `false` for it when translating down. [VV `Protocol1_21_2To1_21_4.java:registerPackets()` `replaceClientbound(LEVEL_PARTICLES)`]
- **`PLAYER_INFO_UPDATE`:** `PROFILE_ACTIONS_ENUM` → `1_21_4` variant (adds "show hat" action). VV writes `true` by default. [VV `Protocol1_21_2To1_21_4.java:registerPackets()`]
- **Item components:** `CUSTOM_MODEL_DATA` → `1_21_4` (format extended), `TRIM` → `1_21_4`.

- **`PLAYER_LOADED` serverbound:** Added at protocol **769 (1.21.4)** — `ServerboundPackets1_21_4.java` includes it at 0x2A, and `EntityPacketRewriter1_21_4.java:63` cancels it downward (`protocol.cancelServerbound(ServerboundPackets1_21_4.PLAYER_LOADED)`), confirming 769 is the introduction boundary. It is not present in the 1.21.2 (768) serverbound enum (0x2A there is `RECIPE_BOOK_CHANGE_SETTINGS`). In 1.21.5 it shifts to 0x2A in the new numbering (`ServerboundPackets1_21_5.java:64`). Source: ViaVersion `v1_21_2to1_21_4/rewriter/EntityPacketRewriter1_21_4.java:63`, `v1_21_2to1_21_4/packet/ServerboundPackets1_21_4.java:64`, `v1_21to1_21_2/packet/ServerboundPackets1_21_2.java` (no PLAYER_LOADED entry).
- VV does NOT add a `ChunkLoadTracker` for 1.21.4 clients — Mojang fixed the rendering bug in this release. [VV `Protocol1_21To1_21_2.java:init()` comment]

<!-- VERIFY: field format change in 773 vs 772 — VV entity rewriter references this packet but full diff not extracted -->
In **773 (1.21.9)** this packet gained two new fields: a **dimension identifier** (string) prepended before the block position, and a **pitch float** appended after the yaw float. ViaVersion's handler reads `BLOCK_POSITION1_14`, gets the current dimension from `tracker(wrapper.user()).currentWorld()`, writes `GLOBAL_POSITION` (dimension string + block position), passthroughs the yaw float, then writes `pitch=0F`. Old format (≤ 772): `BlockPosition + float yaw`; new format (773+): `String dimension + BlockPosition + float yaw + float pitch`. Source: `v1_21_7to1_21_9/rewriter/EntityPacketRewriter1_21_9.java:80–90`; `GlobalBlockPositionType.java` (dimension written as string before position).
