Module locktime 

Shared locktime validation logic for BIP65 (CLTV) and BIP112 (CSV)

Provides common functions for locktime type detection, value encoding/decoding, and validation that are shared between CLTV and CSV implementations.

Enums

LocktimeType

Locktime type (block height vs timestamp)

Functions

check_bip65

BIP65 CLTV core check: validates that transaction locktime satisfies the script requirement. Returns true if valid: tx_locktime != 0, types match, and tx_locktime >= stack_locktime.

decode_locktime_value

Decode locktime value from minimal-encoding byte string

encode_locktime_value

Encode locktime value to minimal-encoding byte string

extract_sequence_locktime_value

BIP68: Extract relative locktime value from sequence number

extract_sequence_type_flag

BIP68: Extract relative locktime type flag from sequence number

get_locktime_type

Determine locktime type from value

is_sequence_disabled

BIP68: Check if sequence number has disabled bit set

locktime_types_match

Check if two locktime values have matching types
