coldkeep v0.2.0 — Crash-Consistency Foundation

[franchoy]

coldkeep v0.2 introduces the crash-consistency foundation of the storage engine.

This release focuses on reliability and operational safety by introducing lifecycle
states, recovery mechanisms, and improved observability.

Highlights

• Logical file lifecycle management
• Chunk lifecycle management
• Retry handling for interrupted operations
• Startup recovery system
• Container quarantine mechanism
• Durable container writes (fsync)
• Improved storage statistics and diagnostics
• Smoke test improvements

The storage engine now detects and safely recovers from interrupted operations
using PROCESSING / COMPLETED / ABORTED lifecycle states.

coldkeep remains an experimental research project and is not production ready.
The on-disk format may change before v1.0.
