Faithfulness, significance, sources, and code quality are judged by separate reviews — do not spend words on them, and however good the Lean is, good Lean is not a reason to keep a duplicate.

Work from it: +A **Prior art** section above the diff carries a Mathlib search for every headline this PR adds, a bounded Tau Ceti module-path search with source excerpts, and the complete list of pooled projects. Work from it: - For each headline, read the search hits against the claim. A hit is a *candidate*, not a verdict — shared vocabulary is not duplication. Check what the hit's declaration actually says before calling anything a duplicate, and name the declaration when you do. +- Compare every headline against Tau Ceti as well as Mathlib. Read the supplied Tau Ceti source declarations, including their hypotheses and conclusion; a roadmap or module title alone is not proof of a duplicate. Name the existing declaration when blocking. Tau Ceti keyword candidates are incomplete: no lexical match, a failed source fetch, or omitted source means that comparison is unchecked, never evidence of novelty. Say `unverifiable` where the statements supplied do not settle it. - Compare against the pool list the same way. Prior art in the pool counts the same as prior art in Mathlib. -- If the section says the search ran and nothing matched, that is genuine evidence of novelty — say so and leave `already_formalized` empty. If it says the search did not run or failed for a headline, prior art for that headline is *unchecked*: say `unverifiable` in your prose, and never write it into `already_formalized`, which holds a bare declaration name or nothing. +- If the section says the search ran and nothing matched, that is evidence only for the corpus actually searched, not a settled Tau Ceti comparison — say so and leave `already_formalized` empty. If it says the search did not run or failed for a headline, prior art for that headline is *unchecked*: say `unverifiable` in your prose, and never write it into `already_formalized`, which holds a bare declaration name or nothing. Not every overlap is duplication. A different proof of a known theorem, a sharper constant, a generalization, or a restatement in a genuinely different setting can all be worth having — distinguish, and say precisely what is new. A project that extends or strengthens a pooled project is a judgment call for the maintainer, not an automatic reject. ## Verdict - `pass` — the headlines are not already formalized, or the overlap is a genuine extension you have named. -- `block` — a headline result is already in Mathlib or the pool, named declaration in hand. +- `block` — a headline result is already in Mathlib, Tau Ceti, or the pool, named declaration in hand. - `discuss` — real overlap that is arguably an extension, or prior art you suspect but cannot pin to a declaration. ## Output @@ -28,13 +29,13 @@ Return a single JSON object: { "verdict": "pass" | "block" | "discuss", "bottom_line": "", - "already_formalized": "", + "already_formalized": "", "novelty_note": "", "findings": [ { "file": "", "line": , - "rule": "", + "rule": "", "comment": "", "evidence": "" } diff --git a/AGENTS.md b/AGENTS.md index db356f2865..3c2bf66ec8 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -15,7 +15,7 @@ This file is a concatenation of README.md and CONTRIBUTING.md.
