Compute — Erdős–Szekeres seven

Verifier plus certificate. Every claimed number needs an independent check that runs from the files in this folder. SAT UNKNOWN is not a bound; search residue is not a lower bound.

Replay everything currently in the folder with:

./run_all.sh

verify_record.py evaluates the published general formulas at k=7 and checks the interval 33 <= ES(7) <= 113. q1/ independently replays the classical lower-bound witness: 32 exact integer points in general position with no seven in convex position. This matches the published lower bound; it does not improve it. q2/ gives a compact signotope SAT encoding, exact geometry and truth-table audits, and a DRAT-checked ES(5) smoke test. Its full 33-vertex run ended UNKNOWN; q2/RESULT.md records the artifact hashes and resource wall.
