+# IdeaShift
+
+IdeaShift measures whether an AI-text detector tracks **who came up with a document's ideas** or **who wrote its
+prose**. It holds 500 seed documents and, for each, six documents written by GPT-5.6 models from prompts that carry
+progressively more of the seed's plan. All 3,000 generated documents are AI-written prose. When the seed is
+human-written, the later levels carry more and more of a person's ideas.
+
+## Construction
+
+- **Seeds:** 500 English web documents from the test split of
+  [IdeaLens-1M](https://huggingface.co/datasets/rishanthrajendhran/IdeaLens-1M), 62-63 per format across eight
+  long-form formats. 237 are human-written and 263 AI-generated, per the Pangram silver labels of that corpus.
+- **Prompts:** for each seed, GPT-5.6 Sol wrote a prompt at each level:
+
+  | Level | The prompt gives |
+  |---|---|
+  | 0 | the document type only |
+  | 1 | a very high-level focus |
+  | 2 | the seed's global themes |
+  | 3 | themes and the sequence of roles |
+  | 4 | themes and the full outline, as a plan to follow |
+  | 5 | the seed's full role-labelled outline, with an instruction to add nothing else |
+
+- **Generation:** one GPT-5.6 model per seed (Sol for 250 seeds, Terra for 125, Luna for 125) wrote a document from
+  each prompt.
+
+An idea detector should flag every document from an AI seed. On human seeds it should flag fewer documents as the
+level rises, because more of the ideas come from the person. A prose detector should flag every generated document.
+
+## Fields
+
+| Field | Description |
+|---|---|
+| `id` | document id; generated documents are `<seed_id>\|<condition>` |
+| `seed_id` | the seed document |
+| `level` | 0-5 for generated documents; null for the seed itself |
+| `level_name` | what the prompt carried |
+| `seed_author` | `human` or `ai`: who wrote the seed (Pangram silver label) |
+| `prose_author` | who wrote this document's prose (`ai` for every generated document) |
+| `generator` | the GPT-5.6 model that wrote the document |
+| `system_prompt`, `prompt` | the exact generation request |
+| `format`, `topic` | WebOrganizer format and topic of the seed |
+| `words`, `text` | the document |
+| `outline` | the paraphrased, role-labelled outline IdeaLens scored (JSON string) |
+| `idealens_p_ai`, `proselens_p_ai`, `pangram4_p_ai` | detector P(AI) as reported in the paper |
+
+## Caveats
+
+- Seed labels are Pangram's silver labels of the whole page, not ground truth about how each page was written.
+- A level describes what the prompt contained, not a measured share of human ideas.
