rUv 161f890ddb fix: apply cargo fmt across workspace and fix CI issues 
- Run cargo fmt --all to fix formatting in 362 files across the entire workspace
- Add PGDG repository for PostgreSQL 17 in CI test-all-features and benchmark jobs
- Add missing rvf dependency crates to standalone Dockerfile for domain-expansion
- Add sona-learning and domain-expansion features to standalone Dockerfile build
- Create npu.rs stub for ruvector-sparse-inference (fixes rustfmt resolution error)

rvf-manifest

Two-level manifest system for tracking RVF segments and coordinating compaction.

Overview

rvf-manifest manages the metadata layer that tracks which segments are active, tombstoned, or pending compaction:

  • Level-0 manifest -- per-file segment directory with CRC32c integrity
  • Level-1 manifest -- cross-file global index for multi-file stores
  • Compaction coordination -- tracks merge candidates and generation numbers

Usage

[dependencies]
rvf-manifest = "0.1"

Features

  • std (default) -- enable std I/O support

FileIdentity Storage

The FileIdentity struct (68 bytes) is stored at offset 0xF00 within the Level0Root reserved area (252 bytes starting at the end of the signature region). This placement is backward compatible: old readers that ignore the reserved area see zeros and continue working normally.

Offset Size Field
0xF00 16 file_id
0xF10 16 parent_id
0xF20 32 parent_hash
0xF40 4 lineage_depth

The read_level0() and write_level0() functions in this crate transparently read and write the FileIdentity at these offsets. The CRC32C checksum at offset 0xFFC covers the entire 4092-byte region including the FileIdentity bytes, ensuring integrity.
