# Source notice

PetitGPT by Yang Qi; selected checkpoint alpha075. Parameter lineage: Base -> P2 step750 -> P3 step320 -> interpolation (0.75 toward P3). Later DeepSeek-response-KD, unified Base-SFT, DPO, soft-KD and LoRA updates are absent.

Pretraining source and tokenizer linkage have been established by the existing digest records. The tokenizer corpus uses six of the eight frozen releases; PES2O and StackExchange occur in pretraining, not tokenizer training. Selected source counts are not per-source consumed-token measurements.

<!-- No new corpus audit is claimed. -->

## Pretraining and tokenizer sources

The following terms are builder-recorded metadata at pinned revisions. Dataset authors and contributors retain their rights. Exact mixture and transport revisions are preserved in the companion PRETRAIN_SOURCE_MIXTURE.csv.

## Instruction components

The collection is HuggingFaceTB/smol-smoltalk, revision `f73fe857d519ff6ac5af2ea67c4d3834da7b8bcc`, default/train. Its pinned card has an Apache-2.0 badge. P2's seven labels are source-column values, not separate repositories. Parent/component correspondence is documentary, not a per-row join; exact component revisions remain unestablished. Parent and component notices below are CURRENT_ONLY observations retrieved on 2026-09-10, not terms proven contemporaneous with training.

The parent publisher limits its Apache grant to its newly generated subsets and points to component-specific terms for incorporated datasets. The self-oss-instruct ODC-By metadata differs from the collection badge; a declaration difference is not proof of legal incompatibility. OpenHermes-2.5 refers to component-specific licences; its empty card licence metadata does not resolve those terms, and exact upstream-component rows for this subset remain unresolved. Ordinary historical unknowns have not been newly resolved.
