Packing Rules - -1. **Small blocks may be packed together** to reduce storage overhead and improve I/O efficiency. - - * Multiple small artifacts can reside in a single physical block. - * Each artifact is mapped in the index to a distinct `(BlockID, offset, length)` within the packed block. - -2. **Large blocks are never packed with other artifacts**. - - * Each large artifact resides in its own block. - * This ensures sequential access efficiency and avoids fragmentation. - -3. **Mixed segments** are **permitted only if necessary**, but discouraged. - - * The store may emit a warning or logging when mixing occurs. - * Indexing and addressing remain consistent; artifacts retain deterministic `(BlockID, offset, length)` mapping. - ---- - -## 4. Segment Allocation Rules - -1. **Small blocks**: - - * Allocated into segments optimized for packing efficiency. - * Segment size may be smaller than large-block segments to avoid wasted space. - -2. **Large blocks**: - - * Allocated into segments optimized for sequential I/O. - * Each segment may contain a single large block or a small number of large blocks. - -3. **Segment sealing and visibility rules**: - - * Same as standard ASL-STORE-INDEX: segments become visible only after seal + log append. - * Determinism and snapshot safety unaffected by block size. - ---- - -## 5. Indexing and Addressing - -* All blocks, regardless of size, are addressed uniformly: - - ``` - ArtifactLocation = (BlockID, offset, length) - ``` -* Packing small artifacts **does not affect index semantics**: - - * Each artifact retains its unique location. - * Shadowing, tombstones, and visibility rules are identical to large blocks. - ---- - -## 6. Garbage Collection and Retention - -1. **Small packed blocks**: - - * GC may reclaim blocks only when **all contained artifacts are unreachable**. - * Tombstones and snapshot pins apply to individual artifacts within the packed block. - -2. **Large blocks**: - - * GC applies per block, as usual. - * Retention/pinning applies to the whole block. - -**Invariant:** GC must never remove bytes still referenced by CURRENT or snapshots, independent of block size. - ---- - -## 7. Determinism Guarantees - -* Deterministic behavior of index lookup, CURRENT reconstruction, and PEL execution is **unchanged** by block size or packing. -* Packing is purely an **implementation optimization** at the store layer. -* All `(BlockID, offset, length)` mappings remain deterministic per snapshot + log. - ---- - -## 8. Configurable Parameters - -* `T_small`: threshold for small vs large block classification -* `Segment size for small blocks` -* `Segment size for large blocks` -* `Maximum artifacts per small packed block` - -These parameters may be tuned per deployment but do not change ASL-CORE semantics. - ---- - -## 9. Normative Invariants - -1. Artifact locations remain deterministic and immutable. -2. Packed small artifacts are individually addressable via `(BlockID, offset, length)`. -3. Large artifacts are never packed with other artifacts. -4. Segment visibility, snapshot safety, and GC rules are identical to standard store rules. -5. Mixed segments are discouraged but allowed if unavoidable; index semantics remain consistent. - ---- - -## 10.
