First attempt via a bare messages.create() API call (claude_convo_.py, no tools bound)
No machine- or source-verified content was produced by this activity. Superseded by d:activity-claude-code-session below, which had actual tool access.
Explicit refusal to fabricate hash/ISCC/compilation/concordance results, on the grounds that no tools were available in that call; produced only a negative-space accounting, itself truncated at max_tokens=16000 before completion.
Claude Code session: retrieval, compilation, axiom audit, grounding, and nanopublication drafting
User specifies the five-step provenance protocol and, on request, the repo URL for Tarski.lean
User reviews NP-A through NP-E before any signing or publication
Pending at the time NP-E was drafted -- this activity node is declared in advance of its own completion, and its outcome (approved / revised / rejected) is not yet an assertable fact. See NP-D for the general rule that unsigned, unpublished status holds for this entire set.
Claude Sonnet 5 (Anthropic Messages API, no tools)
text generation only -- no file access, no shell, no network fetch, no Lean toolchain
Claude Sonnet 5 (Anthropic), running as Claude Code
Bash, file read/write, WebSearch, and an installed elan/Lean 4.32.0 toolchain
NP-A (machine-verified): hashing, ISCC, compilation, axiom audit
NP-B (source-verified): license, authorship, historical citations, concordance spot-check
NP-C (asserted): self-reported claims quoted but not independently verified
NP-D (negative space): explicit non-claims
NP-E (this record): the drafting/review provenance graph itself
This graph is a first-person account of the session's own activities and is therefore self-attested by the same agent (d:agent-claude-sonnet-5) that performed them, checked against no external source -- it is provenance about provenance, not a claim about Tarski.lean itself.
