  "datasetName": "SZL Second Brain — in-repo lane (public projection)",
  "doctrine": "Public projection of the IN-REPO lane of the SZL Second Brain. It is DATA, not a model — a retrieval corpus, never weights. Built deterministically from repo-public text (curated docs, the 269-entry formula corpus, DECLARED ingest takeaways, and the DECLARED Ouroboros invariant codex — definitions only, never live check status). The owner-infrastructure ops doc (OWNER-SETUP.md) is EXCLUDED from this public projection, though it remains in the app-served corpus. A BM25 / similarity score over these chunks ranks lexical overlap; it is NEVER correctness. This is wholly separate from the owner's private Brain, which is never published. Nothing here trains a model, evaluates one, serves inference, or upgrades Λ (Conjecture-1).",
