All notable changes to this package are documented here.

0.0.2

Changed

  • Prepare package discovery metadata and publish the README, changelog and license alongside the existing FAT32 and partition-reader components.
  • Update dependencies to Livt.IO 1.8.1 and Livt.Utils 1.1.1.

0.0.1

Added

  • Transport-independent, read-only FAT32 root-directory listing and file streaming through Livt.IO.IReadOnlyBlockDevice.
  • PartitionReader for unpartitioned volumes, primary MBR FAT32 partitions and GPT Basic Data/EFI partitions, with primary-header and entry-array CRC32 checks.
  • Fat32Geometry for bounded boot-sector parsing, active-FAT selection and cluster-address calculations.
  • ISectorBuffer and SectorBuffer for one retained 512-byte sector, with configurable IRam<byte> storage and SequentialRam block-memory defaults.
  • Fat32Reader with configurable file-size, directory-traversal and GPT-entry limits; fragmented-file chain validation before streaming; retained directory entries; byte-level backpressure; cancellation and explicit terminal results.
  • ShortFileName for ASCII 8.3 filename normalization without truncation.
  • Tests for partition discovery, file/listing behavior, corrupt media, disconnects, cancellation, filename bounds and both block-memory and array storage providers.
  • Public documentation for component ownership, scheduled calls, completion, reset, storage substitution and supported format limits.

Scope

  • 512-byte logical sectors and power-of-two FAT32 clusters up to 32 KiB.
  • Root-directory access by short alias; subdirectories can be listed but are not traversed. Long-name records and volume labels are skipped.
  • GPT revision 1.0 with 128-byte entries and addresses within the 32-bit block API.
  • No filesystem writes, allocation, repair, backup-GPT recovery or whole-file destination memory. Applications own file consumers and memory writers.

Dependencies

  • Published Livt.IO 1.7.0 for memory providers and IReadOnlyBlockDevice.
  • Published Livt.Utils 1.1.0 for IEEE CRC32 calculation.
  • No USB, UART, CLI, board-specific clock or platform dependency.
