| ## Pipeline |
| carry vetted v1.1 shards -> top-up fetch (rows+parquet bulk, offset-cursor resume) -> per-row gates (shape, non_latin, think-balance, dup, license, no_image) -> ONE global dedup index seeded with the carried corpus -> real gpt2 BPE per row -> per-slice pareto (strict) -> domain token-share caps -> deterministic interleave. |

| |
| Single-artifact families carry a concision envelope: at equal correctness |
| the pareto prune now drops bloated rows first, so the mixture teaches |
| tight, dense answers rather than padded ones. |
| |
| ## Files |
| - `train.jsonl.gz` — the mixture (interleaved; shuffle again before packing) |
| - `manifest.jsonl.gz` — per-row index: id, source, domain, turns, gpt2_tokens, tags |
| - `build/v2.0/shards/*.jsonl.gz` — per-source provenance pools |
| - `images.tar.gz` — PNGs referenced by `vision_image`/`vision_plot` rows (`meta.images`) |
|
|
| ## Tag vocabulary (filter, never re-split) |
| `src:<source>` · `domain:<fine>` (agentic_general, agentic_search, agentic_swe, agentic_tool, blender_3d, cad_3d, code_agent, general_sft, godot_dev, reasoning_math, reasoning_sci, reasoning_science, reverse_eng, reverse_engineering, style_house, vision_image, vision_plot, vision_svg) |
| · `turns:<mono|short|mid|deep|mega>` · `tok:<1k|1k-5k|5k-20k|20k-50k|50k+>` |
| · `tools` + `toolcalls:<1-3|4-10|10+>` · `cot` · `multimodal` · `verified` |
|
|
| ## Honest notes |
| - Carried rows keep their v1.0/v1.1 vetting; `meta.license` is per-row. |
| - Carry-only sources: agenticsft/demyagent (upstream license unverified), |
| cadforge_3d (upstream dark since v1.0 — the 14 verified rows are all that exist). |
| - Vision rows' text token share is small by nature: the pixels live in |
| `images.tar.gz`, outside any text token count. Every forge-rendered |
| vision answer is program-verified upstream. |
| - Assistant turns carry `trainable: true` — mask non-assistant turns for loss. |
