LabyrinthBench

A deterministic multi-turn benchmark for local models. No judge anywhere in the loop. The goalpost is set: get to the exit — a run's score is the deepest gate it clears (a gate is one checkpoint in the maze; terms defined in the methodology).

Max depth is the defining metric of a single run; comparison between entries is meaningless without the statistics — rank is the bootstrap lower CI bound on median depth, so a lucky small-n entry self-limits: wide interval, low bound, modest rank until more evidence arrives. Every dealt run counts; aborts score their depth at last commit. Efficiency columns are metrics, never gates.

Harness lane — division: qwen3:14b

Model pinned to qwen3:14b; context strategies compete. Open harness code is mandatory in this lane. The shipped wiping policy demonstrably doesn't win everywhere — beat it. marks the wipe-curated policy.

Seed entries are the board's own runs (pre-season, from the E1a campaign dataset — raw logs in the data annex). They predate the dealer/runner flow, so they carry no artifact hashes; submitted entries will. Integrity ladder and submission flow: methodology.
