Overall the coverage is solid for the primary behaviors, correctly verifies the fix that motivated this PR (the toFixed(2) rounding issue), and doesn't over-specify implementation details. There are two minor gaps worth noting.\n\n---\n\nCritical Gaps\n\nNone. No tests rated 8-10 are missing.\n\n---\n\nImportant Improvements\n\nGap 1 — Test 2 has a silent false-positive scenario when equalWidth is undefined\nRating: 5/10\n\nThe \"equal widths\" test reads the reference value from result.at(1)?.width. If a future change caused equalWidth to be undefined (for example, a bad refactor of the division formula), every remaining column would have width: undefined. The forEach assertion would then be undefined === undefined for each entry, which vacuously passes. The test would produce a green result even though no widths are set.\n\nTest 3 (the sum test) is the only safety net in that scenario — parseFloat(undefined ?? '') = NaN, and NaN !== 80 fails the assertion. So no regression actually escapes the suite today, but Test 2 gives a false confidence signal in isolation.\n\nA simple hardening: add expect(equalWidth).toMatch(/^\\d+(\\.\\d+)?%$/) before the forEach, or expect(typeof equalWidth).toBe('string'). This makes Test 2 self-sufficient rather than relying on Test 3 to catch the same problem with a less descriptive failure message.\n\nGap 2 — No test verifies that remaining column widths are formatted as % strings\nRating: 4/10\n\nTest 1 hard-codes '20%' so the format is verified for the category column. For remaining columns, Test 3 uses parseFloat(result.at(1)?.width ?? ''), which silently strips any unit suffix — parseFloat('13.33px') returns 13.33 just as well as parseFloat('13.333...%'). A bug that used pixel values instead of percentages would pass all three tests. Since this is a UI layout concern, the risk is real but low-severity (it would be immediately visible visually). Asserting expect(result.at(1)?.width).toMatch(/^\\d+(\\.\\d+)?%$/) in the equal-widths test would close this gap.\n\n---\n\nTest Quality Issues\n\nTest 3's toBe(80) is fragile to floating-point accumulation in JS\n\nThe computation remainingCount  parseFloat(result.at(1)?.width ?? '') relies on 6  (80/6) === 80.0 being true in JavaScript's IEEE 754 doubles. It is true today (the multiplication happens to be exact), but this is a coincidence of this specific divisor. If the column count ever changes to a value where 80/N produces a repeating binary fraction that doesn't round-trip, the test could fail spuriously. For example, 7 remaining columns gives 80/7 ≈ 11.4285714..., and 7 * 11.4285714... !== 80 in floating point. A future developer adding a column would see a mysterious test failure.\n\nThe idiomatic fix is to use toBeCloseTo(80, 5) or to assert sum >= 79.99 && sum <= 80.01 explicitly. However, because the current column count (6) does produce an exact result with the current formula, this is a latent rather than active issue.\n\nRating: 4/10 — not urgent, but worth noting before the column list grows.\n\n---\n\nPositive Observations\n\n1. Test 1 is precise and direct. It asserts the exact string '20%', covering both the numeric value and the % unit, for the exact position (index 0). This would catch any regression that reorders columns or changes the category width.\n\n2. Test 3 correctly validates the motivation for this PR. The second commit message (\"drop toFixed(2) so remaining widths sum to exactly 80%\") indicates that a previous iteration rounded each width to two decimal places, producing 6 × 13.33 = 79.98. Test 3 would fail on that code, confirming it is a meaningful regression guard for the bug that was just fixed.\n\n3. The mock setup is clean and behavioral. All seven column-creator mocks return objects with only key, header, sortable, and render — no width property — which means the width properties seen in test assertions must come entirely from the columnsFactory spread logic. The tests cannot accidentally pass because a mock pre-populated the width.\n\n4. The pre-existing tests (getTypeCode behavior) are unaffected and continue to test the column configuration logic orthogonally to the new width tests, keeping concerns well separated.\n\n---\n\nFile Paths Relevant to This Analysis\n\n- /Users/USER/workspace/doctolib/worktrees/doctolib/fhir-2223_fix-column-widths-dmp/packages/@doctolib/national-health-records/src/variants/dmp/factories/columnsFactory.tsx\n- /Users/USER/workspace/doctolib/worktrees/doctolib/fhir-2223_fix-column-widths-dmp/packages/@doctolib/national-health-records/src/variants/dmp/factories/columnsFactory.test.ts",
