+# Frontend Verification Pass
+
+Date: 2026-03-30 UTC
+Owner: Senior Frontend Engineer
+Related issues: HAC-17, HAC-18, HAC-19
+
+## Goal
+
+Verify that the current desktop frontend state remains shippable for QA-facing Linux validation after the recent error-handling, structured-inspector, local-smoke-assist, icon, and packaging updates.
+
+## Evidence Captured
+
+1. Passed: `pnpm --filter @redis-gui/desktop test`
+2. Passed: `pnpm run desktop:build`
+3. Passed: `cargo test -p redis-core`
+4. Passed: `pnpm run desktop:tauri:build`
+
+## Verification Detail
+
+- Frontend tests are 11 green across operator notices, structured inspector rendering helpers, and local smoke fixture helpers.
+- The browser build completes successfully with the current desktop shell and utility-rail assist surfaces.
+- The shared Rust backend core still passes 16 tests.
+- The stable Linux packaging path still emits `.deb` and `.rpm` artifacts under `target/release/bundle/`.
+
+## Current Conclusion
+
+The current repository state is internally consistent for the documented stable Linux path: frontend tests, frontend build, backend tests, and standard `.deb`/`.rpm` packaging all succeed together. The remaining evidence gap is still GUI-capable smoke capture, not repository correctness on the validated build path.
