📝 Walkthrough

Walkthrough

The change adds typed Edge APIs for applying run-diff decisions, exposes these operations through desktop preview capabilities, and routes preview URL resolution through platform adapters. The workbench adds interactive diff handling, read-only fallbacks, and PDF/image content loading states.

Changes

Run diff application and evidence previews

Layer / File(s)	Summary
Run-diff Edge API contracts `app/desktop/src/api/edgeClient.ts`, `app/desktop/src/api/schemas.ts`, `app/desktop/src/__tests__/edgeClient.test.ts`	Adds typed single-hunk and batch apply requests. Maps payloads to snake_case, validates responses, and tests success and Edge error handling.
Platform preview adapters `app/desktop/src/platform/desktopPlatform.ts`, `app/desktop/src/platform/desktopPreview.ts`, `app/desktop/src/platform/desktopPreview.test.ts`, `app/web/src/platform/webPlatform.ts`, `app/web/src/platform/webPreview.ts`	Desktop forwards diff decisions to Local Edge and resolves Edge-relative URLs. Web preserves absolute HTTP(S) URLs and remains read-only for diff application.
Preview capability contract and wiring `app/shared/src/platform/types.ts`, `app/shared/src/platform/index.ts`, `app/shared/src/workbench/rightInspectorTypes.ts`, `app/shared/src/workbench/RightInspector.tsx`, `app/shared/src/workbench/RightInspectorModePanel.tsx`, `app/shared/src/workbench/inspector/InspectorModeBodies.tsx`, `app/shared/src/workbench/workbenchFramePartsHelpers.ts`	Adds preview port types and optional capabilities. Passes the platform preview port through the inspector to file previews.
Interactive preview behavior `app/shared/src/workbench/inspector/FilePreviewRouter.tsx`, `app/shared/src/workbench/inspector/FilePreviewHelpers.ts`, `app/shared/src/workbench/inspector/FilePreviewRouter.apply.test.tsx`, `app/shared/src/workbench/inspector/FilePreviewHelpers.test.ts`, `app/shared/src/workbench/RuntimeEvidenceParts.tsx`, `app/shared/src/workbench/__tests__/inspector.test.tsx`	Routes accept and reject actions through the preview port. Adds success, error, and read-only states. Resolves PDF/image URLs and displays unavailable or load-failure states.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 0a711

The PR changes diff-apply routing and preview status handling, but malformed successful responses may be reported as applied and partially supported apply modes may appear unavailable. Merge should wait for strict response validation and per-operation capability checks.

minimal, and validate.

Inline comments:
In `@app/desktop/src/api/edgeClient.ts`:
- Around line 350-368: Update the mutation response handling in applyRunDiff and
applyAllRunDiffs to use strict schema parsing instead of safeParse, so malformed
successful responses throw rather than being treated as valid. Preserve the
existing schemas, response unwrapping, and operation labels.

In `@app/desktop/src/platform/desktopPreview.test.ts`:
- Around line 15-20: Update the test around resolveDesktopEvidenceContentUrl to
isolate getEdgeBaseUrl configuration by mocking the relevant `@/config` values or
explicitly clearing edge_url, agenthub_edge_url, and VITE_EDGE_URL overrides,
then assert against the controlled base URL rather than relying on the default
http://127.0.0.1:3210.

In `@app/shared/src/workbench/inspector/FilePreviewRouter.tsx`:
- Line 346: Update the fallback detail text rendered in the span containing
detail to use a font size of at least 12px instead of 0.6875rem, while
preserving the surrounding rendering and styling.
- Line 126: Update the apply-support calculation in the FilePreviewRouter
component to evaluate applyRunDiff and applyAllRunDiffs independently, so either
available operation enables apply support and prevents the read-only notice.
Preserve each operation’s existing availability checks and behavior.

In `@app/shared/src/workbench/inspector/RuntimeEvidenceParts.tsx`:
- Around line 93-94: Update the download status label in RuntimeEvidenceParts to
say this panel has no download action, without claiming Hub or Edge lack
artifact content endpoints; keep the export status unchanged. Export both status
labels as constants from RuntimeEvidenceParts and import those constants in
inspector.test.tsx so the tests reuse the UI strings instead of duplicating
them.
