  "tables": {
    "loca": {
      "offsets": null,
      "_checksum": 0

Top-level Fields

• offsets - implementation-defined [spec type: Offset16] (actual offset ÷ 2)

Additional Nested Keys Seen In Implementation

• None inferred from source.

Notes

• Preserve _checksum for stable round-tripping.
• If a table is only partially understood, prefer keeping unknown bytes in _raw instead of dropping data.
• Validate with .validate() after edits.
