name: AetherArena harness gate (ADR-149)
# Runs the AetherArena scoring harness as a PR build gate. Every PR that touches
# the scorer, the metrics, or the benchmark scaffold must keep the deterministic
# score hash stable (ADR-149 §2.5 determinism_gate). If the scoring maths changes,
# the hash moves and this gate fails until `expected_score.sha256` is regenerated
# and reviewed — so scorer drift can never land silently.
#
# This is the "a PR that runs the harness as part of the build process" requirement.
