# Placeholder Labs Artifacts Pool

Private, source-grounded corpus of complete, editable, self-contained HTML slide
decks. The current production release contains 9,066 accepted canonical decks,
34,601,632 unique Dolma-2 HTML tokens, and two linked training views per deck.

- `canonical`: natural request, complete HTML, source lineage, design assignment,
  teacher evidence, and static/browser validation evidence;
- `annealing_html`: raw complete HTML without chat or factory wrappers;
- `sft_create`: natural user request followed by the same complete HTML assistant
  answer.

The two training views are serializations of one accepted artifact, not independent
content. Their combined 73,989,907 message-content tokens repeat the HTML once.
Factory source context, validation ledgers, design assignments, and acceptance
instructions are excluded from training payloads.

Every accepted deck passed pinned-browser rendering, minimum keyboard navigation,
print exposure, clipping, text-size, console, network, fact-preservation, and
anti-pattern checks. The release contains 9,066 unique source lineages and HTML
hashes, all 30 scheduled visual systems, and no detected first-slide or whole-deck
perceptual near duplicate at the release threshold.

Source rows retain per-record provenance and rights evidence. Because the corpus is
a mixture of public-domain, Creative Commons, Apache-licensed, and internally owned
source derivatives, there is no single blanket corpus licence.

Rendered screenshots are content-addressed evidence in private S3 rather than
duplicated inside training JSONL. Canonical rows retain the immutable screenshot
hash and locator.

See `RELEASE.json`, `schema/phase5-10000-v1/`, and
`receipts/phase5-10000-v1/` for release counts, schema, publication, and migration
evidence.
