CARRIER R03 — SOURCE ATTRIBUTION R03 reuses the unchanged R02 source materials below. New R03 synthetic cases, agent outputs and analyses are identified as such. No private dialogue is included. Reference/cache envelopes are experimental code, not a new standardized USL1 profile. The third-party source terms below continue to apply. CARRIER RETRIEVAL LAB R02 — SOURCES AND MODIFICATIONS CORPUS The experiment uses an unchanged checked-tier snapshot of Carrier, prepared in Wikipedia Wave III. Registry: https://www.unifiedstate.us/carrier/ Head: 398492317d139bd78ca599965f08603296daedd95f4fb088fde05393175bfe88 data/checked.jsonl preserves the complete records, including provenance, Wikipedia revision references and links to publication evidence. data/concepts.json is a projection of their names, definitions, relations and colours for retrieval. Existing authorship credits and source terms are retained. Neither checked status nor a matching hash authenticates an author or establishes a claim's truth. Wikipedia-derived text: Wikipedia contributors, Creative Commons Attribution-ShareAlike 4.0 International: https://creativecommons.org/licenses/by-sa/4.0/ https://en.wikipedia.org/wiki/Wikipedia:Reusing_Wikipedia_content Carrier's Wikipedia definitions are compact adaptations with qualifications and contextual links, not unchanged article text. The corresponding original source, revision and publication-evidence links are in each record's provenance and payload fields. Preserve these notices when redistributing the snapshot. Overlay excerpts and definition-derived material retain CC BY-SA 4.0 where applicable. No Wikipedia or Wikimedia endorsement is implied. Pre-existing Carrier concepts drawn from other sources retain their original source and author terms; this notice does not retroactively relicense them. The seven-ray mark identifies Unified State, not an external institution. METHODS AND CODE The new experiment scripts, reports, queries and first-run evidence are supplied for inspection and reproduction. Methodological publications are cited in the protocol and technical report. Their text is not reproduced as part of the corpus. Python packages used to run the study are not bundled in the website or main kit; installations retain their respective upstream licences. MODEL SUPPLEMENT sentence-transformers/all-MiniLM-L6-v2, official model repository: https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2 Revision: 1110a243fdf4706b3f48f1d95db1a4f5529b4d41 The pinned model card declares Apache 2.0. The bundled model/ directory preserves that card, tokenizer, configuration, unmodified ONNX weights and SHA-256 manifest, with the official Apache 2.0 licence text. No remote-code trust or inference API was used. Embeddings are supplied as experiment outputs; they are not definitions or authoritative interpretations of the underlying concepts. PUBLIC QUESTION SOURCES AND ADAPTATIONS Twenty-four retained question bodies come from named Stack Exchange communities. Each source object in benchmark/needs-a.json, needs-b.json and tasks.json records the original title, question URL, author attribution, API URL, retrieval time, original wording, license version and license link. Thirteen supplied source records report CC BY-SA 3.0 and eleven report CC BY-SA 4.0. These notices and links remain with the unchanged source wording and its explicitly marked AI adaptation. The corresponding adapted question portions are distributed under the same source license. Reframing, added conditions and answer obligations are identified as changes; the original question authors did not endorse this study. No accepted answers are bundled as a reference answer set. https://creativecommons.org/licenses/by-sa/3.0/ https://creativecommons.org/licenses/by-sa/4.0/ https://stackoverflow.com/help/licensing The other twenty-four scenarios were prospectively AI-authored without exposure to Carrier. Do not attribute those scenarios or the model relevance judgments to the public question authors. Corpus, question, model and software terms are separate; this file does not retroactively relicense pre-existing materials.
