From 292252d8891ff3697de74e9cf777da498350f913 Mon Sep 17 00:00:00 2001 From: Patrick Gilhooley <113308245+pgil256@users.noreply.github.com> Date: Wed, 3 Jun 2026 09:52:17 -0400 Subject: [PATCH 1/2] =?UTF-8?q?feat(eval):=20composite=20harness=20reports?= =?UTF-8?q?=20chord=20acc=20+=20reuses=20model;=20=C2=A71.4.1=20targets?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add chord-instance accuracy per clip + per-tier bootstrap CI + a report section, so the composite eval reports all SPEC §1.4 metrics together. - Correct DEFAULT_TIER_TARGETS to the §1.4.1 honest audio-only acoustic gates (single-line 0.45, strummed 0.60).
