Records the findings of a review of the whole test suite: three duplicate tests confirmed by comparing coverage profiles, two inaccuracies in TESTS.md, a hand-rolled itoa in seed_test.go, and four tests thin enough to need a decision. Also lists the pairs that share a coverage profile but assert different properties, and the functions whose zero coverage is deliberate, so a later pass does not re-report them. Temporary: delete once the items are done or moved to ROADMAP. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
