From 4d912a04bd2026f2f399f0a866e3310ddd0514c3 Mon Sep 17 00:00:00 2001 From: simonsangla Date: Thu, 16 Apr 2026 18:02:44 +0100 Subject: [PATCH] =?UTF-8?q?feat:=20batch=2011=20=E2=80=94=20close=20all=20?= =?UTF-8?q?batch-10=20inspector=20nits=20(2=20P2=20+=204=20P3=20+=202=20ca?= =?UTF-8?q?vekit=20clarifications)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit T-140 / F-001 — remove dead `e.stopPropagation()` from variant toggle handler. The variant row is a SIBLING of the card button, not a child, so click events never bubble through. Comment was misleading. Test reworded (T-147) to credit the structural separation rather than propagation suppression. T-141 / F-005 — variant aria-label simplified from `"kpi-tile variant"` to `" variant"` (Tile variant / Metric variant). Cleaner SR announcement. T-142 / cavekit-schema R8 (revised) — new acceptance criterion + 3 tests documenting that backslash is intentionally NOT in the blocklist. CSS hex escapes (e.g. `\3b` for `;`) are decoded inside the value token AFTER declaration parsing per CSS Syntax Level 3, so they cannot break the `:root { --shadow-x: VALUE; }` declaration boundary. T-143 / F-002 — replace theatrical render-only assertion with a real CSS-consumption test. Scans `WidgetPreview.module.css` and asserts every theme color slot is referenced via `var(--token)` somewhere — catches token-drop regressions (someone hardcoding `#fff` for the card border, etc.). T-144 / F-003 — replace loose `outerHTML !== outerHTML` comparison with specific `data-variant="metric"` attribute assertion. T-145 / F-004 — split `toCSSVarsVariant` output on `:root[data-theme="dark"] {` and assert each new var appears in BOTH halves. Catches future regression where dark block omits a token. T-146 / cavekit-widgets R4 (revised) — codify that variant toggle is operable regardless of selection state (matches shipped behavior). Add test that asserts toggle renders + responds when kpi-tile is excluded. Validation: lint 0 errors, typecheck pass, test 267/267 (261 prior + 6 new), build pass. Browser confirmed: new aria-labels in place, old labels absent, toggle still flips on click. --- AGENT_HANDOFF.md | 49 ++++++++++++ context/kits/cavekit-schema.md | 2 + context/kits/cavekit-widgets.md | 2 + context/plans/build-site-batch11.md | 74 +++++++++++++++++++ .../WidgetSelector/WidgetSelector.tsx | 8 +- tests/components/WidgetSelector.test.tsx | 45 ++++++----- tests/export/newTokens.test.ts | 17 ++++- tests/persistence/integration.test.tsx | 42 +++++++++-- tests/schema/shadows.test.ts | 35 +++++++++ 9 files changed, 240 insertions(+), 34 deletions(-) create mode 100644 context/plans/build-site-batch11.md diff --git a/AGENT_HANDOFF.md b/AGENT_HANDOFF.md index ef06527..db3641a 100644 --- a/AGENT_HANDOFF.md +++ b/AGENT_HANDOFF.md @@ -1,5 +1,54 @@ # AGENT HANDOFF — theme-forge +## Batch 11 — Nit-pick cleanup (Batch 10 inspector findings) + +**Date:** 2026-04-16 +**Status:** Complete.
