| # FlashMini corpus architecture (v4) |
|
|
| One logical master lake; deterministic views per recipe. Flow: HF/upstream |
| -> registry (`sources.yaml` + immutable `source_snapshot.lock.json`) -> |
| recipe (domain weights) -> bounded cache window -> canonicalize/filter -> |
| exact + MinHash-LSH near-dedupe -> hash-salted train/val split -> |
| Parquet+ZSTD shards (256MiB-1GiB) -> HF publish + remote verify -> evict |
| local -> `RemoteShardDataset` training with hierarchical deterministic |
| sampling and exact resume. Corpus identity: `corpus_fingerprint_sha256` |
| (registry hash, revisions, recipe hash, filter/dedupe versions, split salt, |
| shard hashes, tokenizer identity). |
