+# Release Readiness Checklist
+
+Date: 2026-03-27
+Owner: QA Engineer
+
+## Must Be True Before Redis GUI V1 Can Ship
+
+- A documented build or package path exists for Linux, macOS, and Windows.
+- Smoke steps are executable and repeatable by someone other than the original implementer.
+- Seed data or demo environment is documented and reproducible.
+- Core workflows have explicit pass evidence:
+  - connection management
+  - key browsing
+  - search
+  - value editing
+  - TTL operations
+  - command console
+  - dangerous operation confirmation
+- Known release blockers are triaged with owner and severity.
+- Installer or portable package basic install, launch, and uninstall checks are complete.
+
+## Current Release Blockers On 2026-03-27
+
+- Blocked: Linux package artifact evidence now exists for `.deb` and `.rpm`, but AppImage is still unverified and there is no validated artifact evidence yet for macOS or Windows.
+- Blocked: a repeatable Docker-backed seed and smoke path now exists, but no completed smoke evidence set has been captured from it yet.
+- Blocked: release artifact naming now exists in produced Linux packages, but install and uninstall verification is still not documented with saved evidence.
+- Blocked: the desktop app is not yet validated end-to-end against a seeded Redis path; browse, edit, and TTL controls are inspectable, but broader workflow evidence remains incomplete.
+- Blocked: desktop runtime smoke evidence inside the real Tauri window is still pending even though current `redis-core` Rust test evidence and Linux package artifacts are reproducible from the present tree.
+
+## Minimum Sign-Off Evidence
+
+- Test run log with date, platform, build id, and tester.
+- Screenshots or terminal evidence for each smoke step.
+- Defect list with severity and explicit disposition.
+- Final QA judgment: pass, fail, blocked, or pass with waiver.
