# Packet 65: ProgressBar

> Configures a generic capture/build progress bar with current progress, rate, and a two-colour gradient.

- **Decimal ID:** 65
- **Hex ID:** 0x41
- **Direction:** Inactive
- **Family:** Interface
- **Status:** Planned
- **Evidence:** Provisional
- **Wire size:** 11 bytes

## 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 65 (0x41). | — |
| 1 | `progress` | sign-magnitude fixed16 LE (1/64) | 2 | progress value. | — |
| 2 | `rate` | sign-magnitude fixed16 LE (1/64) | 2 | rate value. | — |
| 3 | `color1` | BGR888 | 3 | Three colour channels written blue, green, then red. | — |
| 4 | `color2` | BGR888 | 3 | Three colour channels written blue, green, then red. | — |

## 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.
