From 7e6cf575073fd63aa9de9f609f285621d62ff691 Mon Sep 17 00:00:00 2001 From: James Ross Date: Sun, 5 Apr 2026 21:17:31 -0700 Subject: [PATCH 01/32] docs: cycle 0010 design + FULL-COVERAGE invariant + coverage ratchet MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Invariant: every source file in src/ must have 100% line coverage. Baseline: 92.12% lines (with barrel file exclusions). Ratchet: vitest coverage thresholds with autoUpdate — coverage can only go up. @vitest/coverage-v8 added as devDependency.
