Detailed Description

Master context representing an open or in‑creation Aaru image.

Contains stream handle, parsed headers, deduplication structures, optical extras, metadata blocks, checksum information, caches, and write-state. Allocate with library factory (or zero‑init + explicit open) and destroy with corresponding close/free routine.

Field grouping:

Core & header: magic, library*Version, imageStream, header.
Optical sector adjuncts: sectorPrefix/sectorSuffix/subchannel plus corrected variants & mode2_subheaders.
Deduplication: inMemoryDdt, userDataDdt*, userDataDdtHeader, mini/big/cached secondary arrays, version tags.
Metadata & geometry: geometryBlock, metadataBlockHeader+metadataBlock, cicmBlockHeader+cicmBlock, tracksHeader.
Tracks & hardware: trackEntries, dataTracks, dumpHardwareHeader, dumpHardwareEntriesWithData.
Integrity & ECC: checksums, eccCdContext, crc64Context.
Index & dedup lookup: indexEntries (UT_array of IndexEntry), sectorHashMap (duplicate detection), deduplicate flag.
Write path: isWriting, currentBlockHeader, writingBuffer(+position/offset), nextBlockPosition.

Notes:

userDataDdt points to memory-mapped or fully loaded DDT (legacy path); userDataDdtMini / userDataDdtBig supersede.
shift retained for backward compatibility with earlier single‑level address shift semantics.
mappedMemoryDdtSize is meaningful only if userDataDdt references an mmapped region.
