# Packet 92: PlaceC4

> Requests an oriented type-38 C4 placement with server-owned stock and ownership tracking.

- **Decimal ID:** 92
- **Hex ID:** 0x5C
- **Direction:** C→S
- **Family:** Deployables
- **Status:** Handled
- **Evidence:** Live-verified
- **Wire size:** 12 bytes

## Implementation note

Corrected raw-voxel layout and two-client retail render lifecycle are verified.

## Exact wire layout

The application packet ID is the first byte. The remaining rows are in decode order. Byte sizes exclude ENet headers, wrapper prefixes, LZF chunk framing, and compression effects.

| # | Field | Encoding | Bytes | Purpose | Condition |
| ---: | --- | --- | ---: | --- | --- |
| 0 | `packet_id` | u8 | 1 | Always 92 (0x5C). | — |
| 1 | `loop_count` | i32 LE | 4 | Simulation-loop stamp used for ordering, prediction, or reconciliation. | — |
| 2 | `position` | 3 × u16 LE | 6 | Raw X, Y, and Z voxel coordinates. | — |
| 3 | `face` | u8 | 1 | Voxel face or placement orientation index. | — |

## Encoding conventions

- `LE` means least-significant byte first.
- `fixed16` is two-byte sign-magnitude at 1/64 precision.
- `orientation16` uses the measured 1/8192 orientation mapping.
- NUL strings consume their encoded byte length plus one `00` terminator.
- Counted arrays repeat immediately in the documented order.
