| # Data Provenance — Clover Image Tiny |
|
|
| This document records the portable data identity for the exact Stage B |
| calibration checkpoint in this package. It deliberately contains no local |
| machine paths, private storage locations, or source-image payloads. |
|
|
| ## Clover fine-tuning corpus |
|
|
| | Field | Value | |
| |---|---| |
| | Dataset | `Spawning/PD3M` | |
| | Pinned revision | `2a5eb24a8dccf245acd8e56341761aee06da0bdf` | |
| | Accepted records | 1,000 image-caption pairs | |
| | Split | 973 train / 17 validation / 10 test | |
| | Shards | 1 deterministic checksummed shard | |
| | Dataset gate license | `CDLA-Permissive-2.0` | |
| | Item status | CC0-1.0 or Public Domain Mark 1.0, recorded per item | |
| | Manifest SHA-256 | `50c1249f1cb0d8d690a9acc451ca10c9432eb5a7f4e26f34acb5462096e72322` | |
| | Preprocessing version | `clover-pd3m-center-crop-512-jpeg95-v1` | |
|
|
| Every accepted manifest row records a stable item ID, caption, split, source |
| organization and URL, item-level status, source MD5, transformed SHA-256, |
| original dimensions and MIME type, crop/resize details, filtering result, and |
| removal status. Preprocessing applies EXIF transpose, a deterministic square |
| center crop, Lanczos resize to 512×512, and JPEG encoding with stripped |
| metadata, quality 95, and subsampling 0. |
|
|
| The captions paired with these accepted items were used as the Stage B training |
| text. They are not represented as a separate, untracked prompt corpus. Neither |
| the source images nor the gated training shard is distributed in this model |
| package. |
|
|
| ## Checkpoint binding |
|
|
| The data identity above is bound to: |
|
|
| - experiment `clover-kd-20260712T050925Z-01KXABNHP0`; |
| - optimizer step 500, microstep 4,000, sample position 4,000; |
| - checkpoint SHA-256 |
| `4a5b99ff18478742528a0d31c97dcee939b166a51be858721d40ad5984110893`; |
| - checkpoint-bundle SHA-256 |
| `384b6515f5f26838aea33ec9a941e06610a20764f0b8637c8b7b0667bfc0d447`; |
| - resolved-config SHA-256 |
| `80cf9395d1f587dc0c1d440d9f5b55c55c20703187998509bb306d19d463f597`. |
|
|
| The bundle digest includes checkpoint metadata in addition to the format-2 |
| resume artifacts, preventing the data identity from being relabeled without |
| changing the approved bundle identity. |
|
|
| ## Foundational upstream provenance limitation |
|
|
| The 1,000-pair manifest fully describes only the additional Clover calibration |
| data. It does not replace or erase the pretraining lineage already embedded in |
| the starting student and frozen teacher. |
|
|
| The pinned BK-SDM-Tiny-2M model card names LAION-Aesthetics V2 6.25+ and |
| 2,256,472 pairs, but does not supply the per-record license and provenance |
| evidence required by Clover's full release policy. Complete per-record |
| provenance for all foundational data behind the upstream student and teacher is |
| therefore not available to this project. The upstream checkpoints and their |
| declared CreativeML OpenRAIL-M licenses are pinned and disclosed, but that is |
| not equivalent to a complete foundational dataset audit. |
|
|
| This inherited scope remains disclosed so downstream users can assess the |
| public release with its complete known lineage context. |
