Hey Codex,

This folder claims a verified solution of Erdős Problem #1186 (see problem.md). Please verify it end to end — trust nothing you don't check:

1. Read problem.md (the exact Erdős problem). Open check_answer/README.md (pinned convention; δ₃ = 117/2192 via the exact 548-cell RLT certificate; the discrete-to-continuum reduction is documented there and in verified_math/F-017_delta3-exact/entry.md) and judge for yourself that the formal statement faithfully encodes the problem — quantifiers, ranges, and edge cases. check_answer/README.md documents the encoding choices; be skeptical and check them.
2. Reproduce the verification from a cold start by running, from this folder:
   cd verified_math/F-017_delta3-exact/checker && cargo build --release
   ./target/release/check-continuum-rlt tests/continuum-rlt-548.txt
   python3 tests/crosscheck_continuum_rlt.py   # needs numpy
   cd ../lean && lake exe cache get && lake build   # kernel-checks the Bell/SOS + RLT certificate schemas
3. Scan the proof sources yourself for escape hatches (sorry, admit, added axioms, native_decide) — scoped to the proof project, excluding .lake build dirs.
4. This solve is certified by exact-arithmetic certificate checkers (integer arithmetic only, independent implementations). Confirm the checkers PASS and read their README for what each certificate proves.

Then give your verdict: does this bundle contain a complete, faithful, kernel-checked solution of the stated problem?
