ADDED Requirements

Requirement: Delta package provides delta manager

The @suaveplan/bitpacker-delta package SHALL expose a DeltaManager that detects changes between successive values and encodes only deltas.

Scenario: Field-level delta encoding

• WHEN two successive objects differ in only one field
• THEN only the changed field is encoded, plus a field-change bitmask

Scenario: XOR delta for numbers

• WHEN two successive numeric values are packed with XOR delta
• THEN the packed size is smaller than full encoding when values are close

MODIFIED Requirements

None.

REMOVED Requirements

None.
