From 1826fceee3553c57ce770420b16caa5cb8ca9188 Mon Sep 17 00:00:00 2001 From: A <258483684+la14-1@users.noreply.github.com> Date: Sat, 14 Feb 2026 21:08:33 -0800 Subject: [PATCH] test: add missing coverage for cmdLast (#1176) Added comprehensive test suite for cmdLast function (PR #1171 feature). Covers: - Empty history (no records) - History with records (rerunning latest) - Record hints and prompt display - Helper functions (buildRecordLabel, buildRecordHint) - Edge cases (old timestamps, metadata fields, selection logic) Tests increased from 13,685 to 13,712 (+27 tests).
