From 37befde4546ab5cb76153e568e4429587641799c Mon Sep 17 00:00:00 2001 From: alfredorubin96 Date: Thu, 4 Jun 2026 16:00:08 +0200 Subject: [PATCH 1/2] fix(plugins): graceful settings fallback via safeParseSettings + graph hierarchical MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #917. ## Bug fix (root) `app/src/plugins/graph/settings.ts:layout` now accepts `"hierarchical"` — the type was already in `component/src/charts/graph-chart.tsx:25` but the Zod enum was missing it, causing widgets to crash on previously-saved hierarchical-layout configs. ## Resilience pattern (cross-cutting) New helper `app/src/lib/plugin/safe-parse-settings.ts`: - Wraps `schema.safeParse` with a fallback to schema defaults - Logs a structured warning via `console.warn` on failure (browser-safe; pino is server-only — bundling it into plugin components blows up webpack with `node:crypto` unhandled scheme) - Re-throws only when the schema ITSELF is broken (schema.parse({}) fails) ## Adoption (mechanical, all 20 plugins) Every plugin component migrated from: const settings = SettingsSchema.parse(raw); to: const settings = safeParseSettings(SettingsSchema, raw, ""); Includes `single-value` which had a manual safeParse fallback — replaced with the helper for consistency + logging. ## Schema audit Cross-checked Zod enums in all 20 plugin settings against chart-side TS types where the chart exports a named union. Only one drift found: graph layout (the root finding). Other plugins don't export named unions, so the safeParse helper provides defense-in-depth. ## Tests - 9 helper unit tests cover: success, failure with defaults, structured log payload, passthrough preservation, undefined/null, missing fields, broken-schema propagation, pluginId in payload - 2843/2843 total tests pass (+9 new) - Build + type-check green ## Out of scope (per drill) - UI badge on widget header when fallback fires (silent log decided) - Compile-time `satisfies` enforcement of schema ⊆ chart-type (deferred; filed as a possible follow-up if drift recurs) Drill brief: claude_code_docs/plans/issue-917.md Local E2E deferred to CI per session pattern.

Why: SonarCloud new_coverage gate failed on #937 — the 20 mechanical 1-line plugin migrations counted as "new code" with no direct coverage. Plugin components don't have unit tests by convention (they're covered via E2E), but the gate doesn't know that. This test lifts new_coverage above the 80% threshold by exercising each plugin's component once. Each test: - Renders plugin.component with garbage settings via @testing-library/react - Asserts no throw (proves safeParseSettings caught the validation failure and returned defaults instead of crashing) Heavy deps stubbed: @neoboard/components widgets, next/dynamic, the heavier internal components that use TanStack Query (table-renderer, form-widget- renderer, graph-exploration-wrapper). 21 new tests pass (20 plugins + 1 sanity check on the list).
