/**
* @brief Writes per-sector tag data (auxiliary metadata) for a specific sector.
*
* This function stores auxiliary metadata associated with individual sectors, such as CD subchannel
* data, DVD auxiliary fields, track metadata, or proprietary tag formats used by specific storage
* systems. Unlike media tags (which apply to the entire medium), sector tags are per-sector metadata
* that provide additional context, error correction, copy protection, or device-specific information
* for each individual sector.
*
* The function validates the tag type against the media type, verifies the data size matches the
* expected length for that tag type, allocates buffers as needed, and stores the tag data at the
* appropriate offset within the tag buffer. Some tags (like track flags and ISRC) update track
* metadata rather than per-sector buffers.
*
* **Supported tag types and their characteristics:**
*
* **Optical Disc (CD/DVD) Tags:**
* - **CdTrackFlags** (1 byte): Track control flags for CD tracks
* - Updates track metadata in ctx->trackEntries for the track containing the sector
* - Includes flags like copy permitted, data track, four-channel audio, etc.
*
* - **CdTrackIsrc** (12 bytes): International Standard Recording Code for CD tracks
* - Updates track metadata in ctx->trackEntries for the track containing the sector
* - Identifies the recording for copyright and royalty purposes
*
* - **CdSectorSubchannel** (96 bytes): CD subchannel data (P-W subchannels)
* - Stored in ctx->sector_subchannel buffer
* - Contains control information, track numbers, timecodes, and CD-TEXT data
*
* - **DvdSectorCprMai** (6 bytes): DVD Copyright Management Information
* - Stored in ctx->sector_cpr_mai buffer
* - Contains copy protection and media authentication information
*
* - **DvdSectorInformation** (1 byte): DVD sector information field
* - Stored in first byte of ctx->sector_id buffer (4 bytes per sector)
* - Contains sector type and layer information
*
* - **DvdSectorNumber** (3 bytes): DVD sector number field
* - Stored in bytes 1-3 of ctx->sector_id buffer (4 bytes per sector)
* - Physical sector address encoded in the sector header
*
* - **DvdSectorIed** (2 bytes): DVD ID Error Detection field
* - Stored in ctx->sector_ied buffer
* - Error detection code for the sector ID field
*
* - **DvdSectorEdc** (4 bytes): DVD Error Detection Code
* - Stored in ctx->sector_edc buffer
* - Error detection code for the entire sector
*
* - **DvdDiscKeyDecrypted** (5 bytes): Decrypted DVD title key
* - Stored in ctx->sector_decrypted_title_key buffer
* - Used for accessing encrypted DVD content
*
* **Block Media (Proprietary Format) Tags:**
* - **AppleSonyTag** (12 bytes): Apple II Sony 3.5" disk tag data
* - Stored in ctx->sector_subchannel buffer
* - Contains file system metadata used by Apple II systems
*
* - **AppleProfileTag** (20 bytes): Apple ProFile/FileWare hard drive tag data
* - Stored in ctx->sector_subchannel buffer
* - Contains file system and bad block metadata
*
* - **PriamDataTowerTag** (24 bytes): Priam Data Tower hard drive tag data
* - Stored in ctx->sector_subchannel buffer
* - Contains proprietary metadata used by Priam drives
*
* **Sector addressing:**
* The function supports both positive and negative sector addressing:
* - Negative sectors: Lead-in area before sector 0 (for optical media)
* - Positive sectors: Main data area and lead-out overflow area
* - Internal correction adjusts addresses to buffer offsets
*
* **Buffer allocation:**
* Tag buffers are allocated on-demand when the first tag of a given type is written. Buffers
* are sized to accommodate all sectors (negative + normal + overflow) and persist for the
* lifetime of the context. Memory is freed during aaruf_close().
*
* @param context Pointer to the aaruformat context (must be a valid, write-enabled image context).
* @param sector_address The logical sector number to write the tag for. Must be within valid
* bounds for the image (0 to Sectors-1 for positive, 0 to negative-1
* when using negative addressing).
* @param negative If true, sector_address refers to a negative (lead-in) sector; if false,
* it refers to a positive sector (main data or overflow area).
* @param data Pointer to the tag data to write. Must not be NULL. The data size must exactly
* match the expected size for the tag type.
* @param length Length of the tag data in bytes. Must match the required size for the tag type.
* @param tag Tag type identifier (from the tag enumeration). Determines which buffer to write to
* and the expected data size.
*
* @return Returns one of the following status codes:
* @retval AARUF_STATUS_OK (0) Successfully wrote sector tag. This is returned when:
* - The context is valid and properly initialized
* - The context is opened in write mode (ctx->isWriting is true)
* - The sector address is within valid bounds
* - The tag type is supported and appropriate for the media type
* - The data length matches the required size for the tag type
* - Memory allocation succeeded (if buffer needed to be created)
* - Tag data was copied to the appropriate buffer or track metadata updated
*
* @retval AARUF_ERROR_NOT_AARUFORMAT (-1) The context is invalid. This occurs when:
* - The context parameter is NULL
* - The context magic number doesn't match AARU_MAGIC (invalid context type)
* - The context was not properly initialized by aaruf_create()
*
* @retval AARUF_READ_ONLY (-13) The context is not opened for writing. This occurs when:
* - The image was opened with aaruf_open() instead of aaruf_create()
* - The context's isWriting flag is false
* - Attempting to modify a read-only image
*
* @retval AARUF_ERROR_SECTOR_OUT_OF_BOUNDS (-4) Sector address is invalid. This occurs when:
* - negative is true and sector_address > negative-1
* - negative is false and sector_address > Sectors+overflow-1
* - Attempting to write beyond the image boundaries
*
* @retval AARUF_ERROR_INCORRECT_DATA_SIZE (-11) Invalid data or length. This occurs when:
* - The data parameter is NULL
* - The length parameter is 0
* - The length doesn't match the required size for the tag type
* - Tag size validation failed
*
* @retval AARUF_ERROR_INCORRECT_MEDIA_TYPE (-26) Invalid media type for tag. This occurs when:
* - Attempting to write optical disc tags (CD/DVD) to block media
* - Attempting to write block media tags to optical disc
* - Tag type is incompatible with ctx->imageInfo.XmlMediaType
*
* @retval AARUF_ERROR_NOT_ENOUGH_MEMORY (-8) Memory allocation failed. This occurs when:
* - calloc() failed to allocate buffer for tag data
* - System is out of memory or memory is severely fragmented
* - Buffer allocation is required but cannot be satisfied
*
* @retval AARUF_ERROR_TRACK_NOT_FOUND (-25) Track not found for sector. This occurs when:
* - Writing CdTrackFlags or CdTrackIsrc tags
* - The specified sector is not contained within any defined track
* - Track metadata has not been initialized
*
* @retval AARUF_ERROR_INVALID_TAG (-27) Unsupported or unknown tag type. This occurs when:
* - The tag parameter doesn't match any known tag type
* - The tag type is not implemented
* - Invalid tag identifier provided
*
* @note Tag Data Persistence:
* - Tag data is stored in memory until aaruf_close() is called
* - Tags are written as separate data blocks during image finalization
* - CD subchannel and DVD auxiliary fields are written by dedicated block writers
* - Track metadata (flags, ISRC) is written as part of the tracks block
*
* @note Buffer Reuse:
* - Some tag types share the same buffer (ctx->sector_subchannel)
* - CD subchannel uses 96 bytes per sector
* - Apple Sony tag uses 12 bytes per sector
* - Apple Profile tag uses 20 bytes per sector
* - Priam Data Tower tag uses 24 bytes per sector
* - Ensure consistent tag type usage within a single image
*
* @note DVD Sector ID Split:
* - DVD sector ID is 4 bytes but written as two separate tags
* - DvdSectorInformation writes byte 0 (sector info)
* - DvdSectorNumber writes bytes 1-3 (sector number)
* - Both tags share ctx->sector_id buffer
*
* @note Tag Size Validation:
* - Each tag type has a fixed expected size
* - Size mismatches are rejected with AARUF_ERROR_INCORRECT_DATA_SIZE
* - This prevents partial writes and buffer corruption
*
* @note Media Type Validation:
* - Optical disc tags require XmlMediaType == OpticalDisc
* - Block media tags require XmlMediaType == BlockMedia
* - This prevents incompatible tag types from being written
*
* @note Multiple Writes to Same Sector:
* - Writing the same tag type to the same sector multiple times replaces the previous value
* - No warning or error is generated for overwrites
* - Last write wins
*
* @warning Tag data is not immediately written to disk. All tag data is buffered in memory
* and written during aaruf_close(). Ensure sufficient memory is available for large
* images with extensive tag data.
*
* @warning Mixing incompatible tag types that share buffers (e.g., CD subchannel and Apple tags)
* will cause data corruption. Only use tag types appropriate for your media format.
*
* @warning For track-based tags (CdTrackFlags, CdTrackIsrc), tracks must be defined before
* writing tags. Call aaruf_set_tracks() to initialize track metadata first.
*
* @see aaruf_write_media_tag() for writing whole-medium tags.
* @see aaruf_write_sector_long() for writing sectors with embedded tag data.
* @see write_sector_subchannel() for the serialization of CD subchannel data.
* @see write_dvd_long_sector_blocks() for the serialization of DVD auxiliary data.
