pub fn decode_md1_string(s: &str) -> Result<Descriptor, Error>Expand description
Decode a Descriptor from a complete codex32 md1 string.
Uses the symbol-aligned bit count returned by unwrap_string (5 × symbol_count),
which is exact at the codex32 layer with ≤4 bits of trailing zero-padding —
well within the v11 decoder’s TLV-rollback tolerance.
