L2 Content Addressed SSD Cache

💾 L2 Content-Addressed SSD Cache

SUCO Grid features a global, team-wide Content-Addressed L2 SSD Cache.

Unlike Icecream or distcc, which re-run compiler passes on unchanged files, SUCO stores preprocessed SHA-256 object hashes in a central SQLite database backed by zstd compression.

🔒 Byte-Identity Invariants

SUCO enforces strict byte-identity rules:

1. Source Normalization: Strips comments, volatile whitespace, and line markers for hash keys.
2. Compiler Flags: Normalizes include paths while preserving execution order.
3. ** provenance Isolation**: Builds inside per-job temporary subdirectories to prevent path leakage in DWARF debug symbols.
