1d9e140e6c Fix Backup/Restore API compilation errors 
- chrono timestamp_opt API: use TimeZone trait method
- VfsError::Io/NotFound: use String literals
- SendFormat: add PartialEq derive
- VfsRaidConfig tests: add disk_paths field
- BackupStats test: use relative timestamps
- HashSet file tracking: use (String, u64) tuple
- BackupStream::receive: clone format before use
- collect_file_data: fix temporary lifetime

All tests pass: 495 markbase-core + 201 smb-server = 696 total

ffc3f03744 Implement block-level checksum: Phase 1-4 complete 
Phase 1: VfsBlockChecksum struct + JSON storage (~240 lines)
- VfsBlockChecksum: offset + SHA-256 hash
- VfsChecksumFile: block_size + algorithm + blocks + file_size
- compute_block_hash() + verify_block_hash()
- ChecksumMode: Lazy (default) + OnRead
- ScrubResult: total/verified/corrupted/repaired blocks metrics

Phase 2: ChecksumFile wrapper (~180 lines)
- VfsFile wrapper with transparent checksum
- Lazy verification (only on scrub)
- Cache of verified blocks
- Update checksum on flush()
- read_at/write_at support

Phase 3: Scrub API (~150 lines)
- scrub_file(): verify single file integrity
- scrub_all(): recursive directory scrub
- create_checksums_for_file(): generate checksums
- repair_block(): placeholder for RAID/Dedup

Phase 4: RAID repair integration (~160 lines)
- repair_block_from_parity(): reconstruct from RAID parity
- reconstruct_from_p(): XOR reconstruction for RaidZ1
- reconstruct_from_pq/pqr(): placeholder for RaidZ2/3

Tests: 15 checksum tests pass (465 total)

Files:
- markbase-core/src/vfs/checksum.rs (NEW)
- markbase-core/src/vfs/checksum_file.rs (NEW)
- markbase-core/src/vfs/raid.rs (MOD +160 lines)

57fd6a475f macOS Time Machine AFP monitoring: backup_time update on file modification 
- Added afp_monitor.rs module to track AFP_AfpInfo backup_time
- Open struct now has 'modified' flag to track file modifications
- write.rs sets modified=true on successful write
- close.rs calls AfpMonitor::update_backup_time() on modified files
- create.rs calls AfpMonitor::init_afp_info() on new file creation
- AFP_AfpInfo stored as xattr com.apple.aapl.AfpInfo
- backup_time updated to current epoch time on modification

Also includes:
- LZ4 compression using lz4_flex crate
- Case sensitivity conditional on backend capabilities
- LDAP cfg feature gate fix
- RAID rebuild reconstruction implementation
- DOS attributes xattr persistence
- Snapshot disk persistence

Tests: 201 smb-server, 452 markbase-core (653 total)

9b02bbac27 A: Code quality improvements - fix clippy warnings
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
- Remove unused imports in server.rs (Body, HeaderValue, RwLock)
- Remove unused imports in forward_acl.rs (tests still need Ipv4Addr)
- Remove unused imports in host_key.rs (Read, Write)
- Remove unused imports in kex_exchange.rs (HostKeyType)
- Remove unused imports in known_hosts.rs (tests need Ipv4Addr)
- Remove unused imports in multiplex.rs (Arc)
- Auto-fix other unused imports via clippy --fix

Tests: 303 passed, 0 failed (4 new tests added)

4afd96c9ac Implement VFS RAID-Z (software RAID)
Some checks failed
Test / test (push) Has been cancelled
Details
Test / build (push) Has been cancelled
Details 
- Add VfsRaidLevel enum:
  - Single (no RAID)
  - RaidZ1 (single parity, similar to RAID 5)
  - RaidZ2 (double parity, similar to RAID 6)
  - RaidZ3 (triple parity)
- Add VfsRaidBackend with:
  - Stripe-based data distribution across disks
  - Galois Field arithmetic for parity (P/Q/R)
  - gf_exp, gf_mul for Reed-Solomon coding
  - rebuild_disk() for disk recovery
- Add VfsRaidConfig:
  - level (RAID level)
  - stripe_size (default 64KB)
  - disk_paths (storage devices)
- All VfsBackend methods propagate to all disks
- Foundation for ZFS-style software RAID

All 229 tests pass.
