  d:negspace-Tarski-lean a d:NegativeSpaceRecord;
    rdfs:label "Explicit record of what is NOT claimed about Tarski.lean by this nanopublication set";
    d:noClaimOfMathematicalNovelty "Nothing in this set claims the mathematics is novel. The artifact's own header credits Euclid, Pasch (1882), Hilbert (1899), Tarski (1926-27), Szmielew, Schwabhauser, Gupta, and the GeoCoq project as prior art; this session did not re-verify the Pasch (1882) or Hilbert (1899) attributions specifically (only the Tarski/Givant 1999, SST 1983, and GeoCoq citations were checked, per NP-B) -- their absence from NP-B's checked-citation list is itself a gap, not a confirmation.";
    d:noCodeReviewRecord "GitHub's commit API shows commit 802b1d5's author and committer are both attributed to the same person (Myles Axton, with GitHub as a formal API-committer identity) on the main branch directly -- no separate reviewer, no pull request, no second-party sign-off was found for this commit.";
    d:noCryptographicSignatureYet "As of this record's drafting, none of the five nanopublications in this set (NP-A through NP-E) has been cryptographically signed or published to a nanopub registry. They exist only as unsigned draft TriG files pending the artifact author's explicit instruction to sign and publish, per this session's own operating rules.";
    d:noDraftingProcessVerification "No session transcript, chat export, or other record of the claimed Claude-assisted drafting process was available to check. NP-C records the claim as self-reported only.";
    d:noFullChapterVerification "The 1983 Schwabhauser-Szmielew-Tarski book was not opened cover-to-cover to check every 'SST n.m' tag against its actual content. Only the SST-7.13 / GeoCoq-l7_13 pairing was spot-checked (NP-B). Chapters 2, 3, and 4 attributions (Stages 1-3, and the Ch04 block) remain unverified against the primary source.";
    d:noIsccRegistryLookup "The ISCC codes in NP-A were computed locally with iscc-core v1.3.0 against the fetched bytes. No lookup was performed against any ISCC registry or declaration service to check whether this ISCC has been previously declared, licensed, or associated with a different claimed origin.";
    d:noLicenseForThisProvenanceRecord "NP-A through NP-E declare cc:by 4.0 licensing on themselves (the provenance record), which is independent of and should not be confused with the Apache-2.0 license on Tarski.lean itself (recorded in NP-B).";
    d:noOriginalityDiffPerformed "No line-by-line diff of this file's proof terms against GeoCoq's Coq source was performed. 'Does not port GeoCoq code' is the author's assertion (NP-C), not an independently verified fact.";
    d:noPriorDraftWithdrawn "This session found no earlier draft of this provenance record (by this agent or another) to withdraw or supersede. If one exists elsewhere and asserted machine- or source-verified status without the retrieval/compilation/grounding actually being performed, that hypothetical prior claim is treated as withdrawn by omission: it is not carried forward or relied upon here.";
    d:noTrustyUriYet "None of these records has a trusty URI yet. Cross-references between NP-A/B/C/D/E in this draft use a shared stable external namespace (https://provenance.example/tarski-lean/) rather than each other's nanopub-internal sub: IRIs, specifically so the references keep resolving before and after signing -- but no record here is yet independently retrievable via a resolvable trusty URI." .
