Release/v0.0.4

[0.0.4] - 2026-04-25

Changed

• Added a Windows-specific default config for ojo-syslog (services/syslog/syslog.windows.yaml) so Windows uses ETW-oriented defaults while Linux continues to use services/syslog/syslog.yaml.
• Updated ojo-systrace to namespace Windows-derived trace components as windows.* instead of reusing Linux kernel.* names, keeping the Windows trace shape compatible without sharing Linux naming.

Efficient Archiving

• Archives are now significantly more compressed and lightweight. Each service can be independently tuned via the YAML config, with full control over format, compression, retention, and archival strategy.

storage:
  archive_enabled: true
  archive_dir: data/ojo
  archive_format: parquet         # columnar storage for efficient reads
  archive_compression: zstd       # high-ratio compression
  archive_mode: trend             # archive strategy  (`trend`, `lossless`, `forensic`)
  archive_window_secs: 60         # rolling window per archive cycle
  archive_max_file_bytes: 67108864  # 64 MiB per file
  archive_retain_files: 8         # number of archive files to retain
  archive_file_stem: ojo-snapshots

Fixed

• Fixed trend aggregation first-sample accounting in host-collectors so the first point in a window is no longer double-counted.
• Fixed parquet archive persistence in host-collectors so repeated writes preserve previously written active-file batches instead of truncating earlier archive data.
