Acquire and freeze ContextTrace-Unseen-v1 with source/domain/time-disjoint natural RAG traces

[samarth1412]

Objective

Acquire and publish the unlabeled ContextTrace-Unseen-v1 manifest before any semantic_core_v2 implementation or evaluation. This follows #30.

Deliverables

• 300--500 Natural OOD traces spanning software/product documentation, policy/regulatory documents, and support/operational knowledge bases.
• Approximately 100 temporal/source-condition traces from versioned or authority-contrasting document pairs.
• BM25, vector, and hybrid retrieval; multiple chunking/reranking settings; at least two pinned generator models; clean and naturally failing answers.
• Immutable source snapshots, hashes, canonical URLs, source families, domains, and publication windows.
• Leakage audit proving separation from all calibration sources.
• Published unlabeled IDs/configuration manifest and SHA-256 before scoring.
• Independent annotation and sealed adjudication records following benchmarks/contexttrace_unseen_v1/ANNOTATION_MANUAL.md from Freeze calibrated verifier and prepare Unseen-v1 evaluation #30.

Exclusions

Do not run ContextTrace on candidates before the manifest is frozen. Do not manually author failures, inspect sealed labels during model development, begin TRAIL transfer, recruit human-study participants, or include 1.2 performance and dashboard work in this issue.

Exit condition

Close when the public unlabeled manifest/hash and leakage report are available and the sealed-label custodian confirms that annotations are ready for one-time scoring after the preregistration lock.
