⚠️ Breaking Change

The on-disk repository format has changed to enable append-only repositories (mutable manifest removed). Existing repositories created with v0.11.x are not compatible. You must run vykar delete followed by vykar init to re-create them. This will permanently remove all existing backup data in the repository — ensure you have alternative copies of critical data before upgrading.

Features

• Append-only repository layout — Eliminate the mutable manifest for a simpler, more robust on-disk format.
• TOFU repository identity pinning — Prevent silent repo swaps by pinning the repository identity on first use.
• YAML-driven scenario runner — Automated backup testing via declarative YAML scenario files.
• Proptest round-trip properties — Property-based tests for crypto, serde, and backup pipelines.

Bug Fixes

• Batch-verify packs via shard listing — Fix verify_delta_packs to use shard directory listing instead of index walk.
• REST server backward-compat — Handle v1 repo format manifest key for older repositories.
• Harden config parsing and local write durability — Stricter config validation and fsync guarantees.

Testing

• Proptest property tests for the CDC chunker.
• Corruption fixture matrix tests for vykar check.

Infrastructure

• Bypass faker-file for fast corpus generation (30s → 1s).
• Consolidate scripts into single testbench Python project.
• Migrate benchmark script to Python.

Docs

• Clarify that each source entry produces its own snapshot.
• Expand exclude patterns section with syntax reference and common mistakes.
