| - Field must be named `compression_info` | ||
| - Type must be `CompressionInfo` (not `Option<CompressionInfo>`) | ||
| - Must be **first or last** field in the struct | ||
| - Excluded from `PackedT` struct (saves 24 bytes in compressed form) |

can clients still deserialize the compressed acc data using their regular UserRecord struct? is "compressed form" here != "when the account is compressed/cold"?

yeah compressed account and account state both have CompressionInfo we just dont send it in instruction data
The LightAccount macro generates structs with non-Option CompressionInfo as the first field, but extract_compression_info was trying to deserialize Option<CompressionInfo>. This caused all PDA tracking to fail silently.

it seems compression_authority isn't checked against config / nor signer checked
