Module origin_path 

Origin-path-decl block per spec §3.4.

Block format:

• shared mode (bit 4 = 0): [n: 5 bits, encoded n-1][origin-path-encoding]
• divergent mode (bit 4 = 1): [n: 5 bits, encoded n-1][origin-path-encoding × n]

origin-path-encoding (explicit-only per D19′): [depth: 4 bits][component × depth]

component: [hardened: 1 bit][value: LP4-ext varint]

Structs

OriginPath

An explicit BIP-32 origin path (a sequence of PathComponents).

PathComponent

A single BIP-32 path component (e.g. 84' or 0).

PathDecl

A path declaration: key count n plus either a shared origin path or n divergent origin paths (mode selected by header bit 4).

Enums

PathDeclPaths

Path payload for a PathDecl.

Constants

MAX_PATH_COMPONENTS

Maximum number of components in a single origin path (4-bit depth field).
