+## Electron Runtime Gate Policy
+
+The Electron test lane enforces the following gate policy for GPU/graphics
+requirements:
+
+### GPU Requirements
+
+| Capability | Required? | Notes |
+|---|---|---|
+| **WebGPU** | Optional | Preferred for vector operations and TransformersJs device; CI runners lack GPU access |
+| **WebNN** | Optional | Preferred for ML inference; not available on most CI runners |
+| **WebGL** | Required (software OK) | Minimum graphics capability; software-rendered via Xvfb in Docker |
+| **WASM** | Required | Always-available compute fallback for vectors and embeddings |
+| **OPFS** | Required | Origin Private File System for vector persistence |
+| **IndexedDB** | Required | Metadata and hierarchy persistence |
+
+### CI Gate Behaviour
+
+- **Host-shell Electron** may crash with `SIGSEGV` in headless sandbox
+  environments that lack a GPU. This is **not** a blocking failure — use the
+  Docker lane instead.
+- **Docker Electron lane** (`npm run docker:electron:up`) runs with Xvfb
+  software rendering. WebGL reports as available but WebGPU does not.
+  This lane is **not** a GPU-realism gate — it validates application startup,
+  IPC wiring, and storage initialisation.
+- Set `CORTEX_ALLOW_ELECTRON_SKIP=1` to soft-skip the **full Electron runtime
+  tests** (driven by `scripts/run-electron-runtime-tests.mjs`, typically via
+  `npm run test:runtime`) when hardware is unavailable. The smoke-test runner
+  (`scripts/run-electron-runtime-smoke.mjs`, typically via
+  `npm run test:electron`) does **not** honor this variable and will still
+  fail if Electron is not installed or cannot start.
+- The CI workflow does **not** run Electron tests by default. Full Electron
+  runtime tests are gated behind the `test:runtime` script and should be run
+  manually or in a dedicated GPU-enabled runner. The `test:electron` script
+  is a lightweight smoke test and remains a hard failure if Electron is
+  unavailable.
+
+### Decision Matrix
+
+| Environment | Electron tests run? | GPU available? | Expectation |
+|---|---|---|---|
+| Local (with GPU) | Yes | Yes | Full pass |
+| Local (no GPU) | Skip full runtime tests (`CORTEX_ALLOW_ELECTRON_SKIP=1`) | No | Skip full harness gracefully; smoke tests may still fail without Electron |
+| CI (ubuntu-latest) | No | No | Unit tests only |
+| Docker lane | Yes (software render) | No | Startup + storage pass; WebGPU tests skipped |
