# Erdős frontier — proof status

*Regenerated 2026-07-02 by [`erdos_frontier.py`](../erdos_frontier.py). Do not edit by hand.*

This is a **computed** view, not a hand-kept list. It joins erdosproblems.com, Formal Conjectures, hosted Lean proof indexes, live open PRs, and explicit human overrides on the problem number so the status cannot drift silently.

Proof-source marks: ᵖ = [`plby/lean-proofs`](https://github.com/plby/lean-proofs), ʲ = [`Jayyhk/erdos-lean`](https://github.com/Jayyhk/erdos-lean), ʷ = [`williamjblair/lean-proofs`](https://github.com/williamjblair/lean-proofs).

**Coverage:** all 473 problems Bloom marks formalized are tracked by plby ∪ Jayyhk ∪ williamjblair/lean-proofs ∪ FC. No gap.

Reconciled **1217** problems.

| status | count | meaning |
|---|---:|---|
| `statement` | 66 | **Write the FC statement + link.** A complete hosted proof exists, FC has no file yet. |
| `link` | 0 | **Add the `formal_proof` link.** FC already has the statement; the hosted proof just is not linked. |
| `needs-statement-update` | 1 | **Not a trivial link.** FC has a file, but the statement or answer needs a human update before linking. |
| `needs-human-match-check` | 2 | **Needs match-check.** A hosted proof exists, but the proof/statement relation has not been audited. |
| `mismatch` | 2 | **Skip for now.** The hosted proof is complete, but it does not prove the boxed FC statement. |
| `hypothesis-conditional` | 7 | **Do not link as complete.** The theorem carries a non-problem hypothesis even if `#print axioms` is clean. |
| `docstring` | 8 | **Docstring note, not a `formal_proof` tag.** The hosted proof is conditional, axiomatic, or trust-extended. |
| `partial` | 7 | **Partial proof.** Proves a variant, not the full erdosproblems statement. |
| `blocked-claim` | 3 | **Claimed outside an open PR.** Skip until the claim is resolved. |
| `in-pr` | 319 | **Claimed by an open FC PR.** Skip to avoid collisions. |
| `wont-fix` | 1 | **Maintainer marked `won't fix`.** Skip. |
| `defer` | 0 | **Deferred.** A human override says to leave this out of the next batch. |
| `done` | 91 | Already linked in FC. |
| `no-proof` | 710 | No hosted Lean proof to link yet. |

Human override judgments live in [`overrides.yaml`](overrides.yaml). They encode known claims, theorem mismatches, and conditional-proof traps that are not visible in the upstream machine-readable sources.


## `statement` — 66 problem(s)

**Write the FC statement + link.** A complete hosted proof exists, FC has no file yet.

_none_

## `needs-statement-update` — 1 problem(s)

## statement fidelity — 15 signed verdict(s)

Signed statement-fidelity verdicts: a reviewer attests whether the formal theorem faithfully states the boxed problem. A signed verdict supersedes the computed bucket and any matching `overrides.yaml` row.
