pub const MAGIC: [u8; 4];Expand description
Magic bytes that prefix every stabilized cache entry.
An ASCII tag (0x4C 0x43 0x45 0x31) chosen so it cannot collide with any
pre-stabilization blob: those began with either a small little-endian
length (tens of bytes) or a small tag byte, never these values.
Exported so backends can cheaply identify Lance cache entries (e.g. when
scanning a persistent store at startup) without hardcoding the bytes —
prefer has_cache_envelope over comparing against this directly.
