feat: Edge-AI Perfection Cycle — Phases 0–7 complete#66
Merged
Conversation
Completes the full 7-phase Edge-AI Performance Audit & Perfection Cycle, elevating the inference stack from ONNX stubs to a production-ready, hardware-adaptive system with GPU compute shaders and local telemetry. ## Phase 1–4 Hardening (A1–A6) - A1: Replace fetch()-based WGSL shader loading with Vite ?raw imports — shaders now bundle inline and work correctly in production dist builds - A2: Remove abandoned attentionForward workgroup kernel (needs f32 atomics unavailable in WGSL 1.0); attentionForwardSerial is the only entry point - A3: Add 4096 clamp guard in encodeMlpUniforms() + WGSL comment - A4: Extend tab-leader election guard to Transformers.js WebGPU layer - A5: Size-aware MLC→ONNX model ID mapping (not always SmolLM2-135M) - A6: Complete latency recording test assertion in adaptiveAiEngine tests ## Phase 5 — Domain Integration (B1–B7) - B1: GPU batch cosine in localRagService via batchCosineGpu() + WebGPU similarity pipeline; CPU fallback when flag off or WebGPU unavailable - B2: New hooks/useAdaptiveAi.ts — deviceProfile, warmedModels, isEco, getTaskConfig, prewarmModel; eco-mode subscriber; 30s profile refresh - B3: New AdaptiveAiHardwarePanel — backend badges, VRAM tier, battery, warmed models display; wired into AiSections.tsx settings page - B4: listenerMiddleware adaptive AI flag listeners — enable triggers generateDeviceProfile; disable releases WebLLM/ONNX GPU resources - B5: Voice eco-mode battery coupling — useVoice.ts + voiceCommandService subscribe to ecoModeService; battery <30% forces WebSpeech backend - B6: 11 new settings.ai.adaptive.* i18n keys in 5 locales (2139 total) - B7: 5 new Stryker mutation targets for adaptive AI modules ## Phase 6 — Benchmarks & Telemetry (C1–C2) - C1: New benchmarkService.ts — 3-run micro-benchmarks per task/backend, discards warm-up, feeds latency back to adaptiveAiEngine history - C2: New telemetryService.ts — DuckDB ai_telemetry table + localStorage fallback; fire-and-forget integration in localAiFacade.ts ## Phase 7 — Final Validation (D) - Add @domain/ai-core path to tsconfig.json (resolves known tech-debt) - AUDIT.md: full Edge-AI cycle documentation with resolved debt items - AGENTS.md: Local Inference + WebGPU Compute Shaders sections updated - graphify: rebuilt (2640 nodes, 3343 edges, 625 communities) - docs/EDGE_AI_PERFECT_PLAN.md and WIEDERAUFNAHME.md marked complete Quality gate: lint ✅ · i18n:check ✅ (2139 keys × 5 locales) · unit tests ✅ (122+ regression + 60+ new Edge-AI tests) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Suggestion: Replace the hardcoded fallback text with a translated i18n key so the unavailable VRAM value is localized. [custom_rule]
Severity Level: Minor
Why it matters? 🤔
The fallback value 'N/A' is hardcoded English text in a user-facing string. If the custom rule requires localization of visible copy, this is a real violation because the unavailable VRAM value is not translated through the i18n system.

This is a hardcoded English status label rendered directly to the UI. It is not routed through t(...), so it violates a localization rule for user-facing strings.

The tooltip includes hardcoded English state words, 'available' and 'unavailable', instead of translated values. This is a genuine i18n violation if the project requires localized user-facing text.

🟠 Architect Review — HIGH
telemetryService is documented as being gated by the enableDuckDbAnalytics flag, but recordInferenceTelemetry() is always invoked and always persists entries (DuckDB first, localStorage fallback), so inference telemetry is stored even when analytics is disabled.
Suggestion: Add an explicit feature-flag/consent gate before recording telemetry — either inside recordInferenceTelemetry (reading enableDuckDbAnalytics from state) or at call sites like services/localAiFacade.ts before importing telemetryService — so that when analytics is disabled, no entries are written to DuckDB or localStorage.

Suggestion: Eviction/removal only deletes cache entries and never performs engine teardown, so GPU/wasm resources are not explicitly released when cache pressure occurs. This defeats the memory-pressure handling goal and can cause persistent memory growth after model churn; invoke the engine's cleanup API before deleting entries. [missing cleanup]
Severity Level: Major ⚠️
- ⚠️ Evicted WebLLM engines may retain GPU or WASM allocations.
- ⚠️ Memory-pressure handlers less effective for sustained WebLLM usage.Steps of Reproduction ✅
1. Use the optimizer API to create multiple engines by calling `getWebLlmEngine` with
different modelIds so `engineCache` size reaches `MAX_CACHED_ENGINES = 2` (defined at
`packages/ai-core/src/webllmOptimizer.ts:42`).
2. Call `getWebLlmEngine` again with a third `(modelId, powerPreference)` so the eviction
branch at lines 68-81 runs: it scans `engineCache`, picks `oldestKey`, and executes `if
(oldestKey) { engineCache.delete(oldestKey); }` at lines 78-80.
3. Observe that eviction only removes the cache entry; there is no call to any
cleanup/teardown method on the underlying `MLCEngine` type in this file (interface at
lines 9-18) or in `releaseWebLlm` / `releaseAllWebLlmEngines` at lines 129-138, so the
library is never asked to release GPU/WASM resources.
4. Contrast this with the ONNX path in `packages/ai-core/src/onnxRuntimeEngine.ts`, where
eviction at lines 97-118 and explicit release functions at lines 176-205 always call
`await session.release()` before deleting cache entries, demonstrating that explicit
teardown was intended for long-lived sessions but is currently missing for WebLLM engines.Fix in Cursor | Fix in VSCode Claude

| export function releaseWebLlm(modelId: WebLlmModelId, powerPreference?: PowerPreference): void { | ||
| const key = getCacheKey(modelId, powerPreference ?? 'high-performance'); | ||
| engineCache.delete(key); |
There was a problem hiding this comment.
Suggestion: releaseWebLlm defaults to 'high-performance' when powerPreference is omitted, so a cached 'low-power' engine for the same model is not removed. This leaves stale entries in cache and prevents expected memory release when callers pass only modelId; either remove both variants or require explicit preference. [logic error]
Severity Level: Major ⚠️
- ⚠️ Low-power WebLLM engines remain cached after releaseWebLlm calls.
- ⚠️ Memory usage stays elevated despite attempted engine release.Steps of Reproduction ✅
1. Pre-warm a low-power engine using the public API: call `await
prewarmWebLlm('Qwen2.5-0.5B-Instruct-q4f16_1-MLC', 'low-power')` (defined at
`packages/ai-core/src/webllmOptimizer.ts:117-122`), which internally calls
`getWebLlmEngine` and caches the engine under key `getCacheKey(modelId, 'low-power')`.
2. Verify the cache contents via `listCachedWebLlmEngines()` at lines 144-155; it will
return an entry with `modelId: 'Qwen2.5-0.5B-Instruct-q4f16_1-MLC'` and `powerPreference:
'low-power'`.
3. Now attempt to free that model by calling
`releaseWebLlm('Qwen2.5-0.5B-Instruct-q4f16_1-MLC')` without specifying the
`powerPreference`, which is allowed by the signature at line 129.
4. Inside `releaseWebLlm`, the function computes `const key = getCacheKey(modelId,
powerPreference ?? 'high-performance');` at line 130, so it uses `'high-performance'` when
no preference is passed; it then deletes only that key at line 131, leaving the
`'low-power'` cache entry untouched, so the engine remains resident even though the caller
reasonably expected "release by model id" to clear all variants.Fix in Cursor | Fix in VSCode Claude

Suggestion: This listener only reacts to a false→true transition, so when enableAdaptiveAiEngine is already true from persisted state at app startup, the effect never runs and the global adaptive gate is never initialized. As a result, adaptive routing in local inference remains off until the user toggles the flag manually. Add an initialization path (or a startup action) that sets the gate/profile from current state, not only transitions. [incorrect condition logic]
Severity Level: Major ⚠️
- ⚠️ Adaptive AI engine ignored after reload despite flag enabled.
- ⚠️ Local inference continues using legacy non-adaptive routing.
- ⚠️ Users must re-toggle flag each session for adaptive path.Steps of Reproduction ✅
1. In a running app, toggle the adaptive AI engine feature flag on via any UI that
ultimately dispatches `featureFlagsSlice.actions.setEnableAdaptiveAiEngine(true)` (defined
in `features/featureFlags/featureFlagsSlice.ts:200-201`). The
`featureFlagsPersistenceMiddleware` at `features/featureFlags/featureFlagsSlice.ts:3-14`
persists this change to `localStorage` under `storycraft-feature-flags`.
2. Reload the app so that state is reconstructed from persisted feature flags. On startup,
`loadFeatureFlagsState()` in `features/featureFlags/featureFlagsSlice.ts:101-117` reads
from `localStorage` and sets `initialState.enableAdaptiveAiEngine` to `true` (default is
`false` at `features/featureFlags/featureFlagsSlice.ts:93-94`, but persisted value
overrides it).
3. The Redux store is created in `index.tsx:187-193` by calling
`setupStore(preloadedState)` (defined in `app/store.ts:162-199`), which uses that
`initialState` for the `featureFlags` slice. From this point onward, every dispatched
action sees `prev.featureFlags.enableAdaptiveAiEngine === true` and
`curr.featureFlags.enableAdaptiveAiEngine === true` in the listener middleware.
4. The adaptive enable listener in `app/listenerMiddleware.ts:364-381` uses the predicate
`return curr?.enableAdaptiveAiEngine === true && prev?.enableAdaptiveAiEngine !== true;`
at line 368, so it only fires on a `false → true` transition. After a reload with the flag
already `true`, there is no such transition; the predicate never matches, the effect never
runs, and `__storycraft_adaptive_ai__` is never initialized on `window`. When local
inference is invoked through `services/localAiFacade.ts:16-37` (e.g.,
`generateLocalText()` callers in `components/settings/AiSections.tsx:263-276`), the gate
check `adaptiveEnabled = typeof window !== 'undefined' && (window as Record<string,
boolean>)['__storycraft_adaptive_ai__'] === true;` at `services/localAiFacade.ts:16-18`
evaluates to `false`, so the adaptive engine path is not used even though the feature flag
is enabled from persisted state.Fix in Cursor | Fix in VSCode Claude

Suggestion: This direct window write is unguarded and executes before the try/catch, so in non-browser contexts (SSR/tests/worker-like runtimes) it throws ReferenceError and breaks the listener effect. Guard with typeof window !== 'undefined' before touching window. [possible bug]
Severity Level: Major ⚠️
- ⚠️ Node-environment tests using the store can crash on toggle.
- ⚠️ Any future SSR usage of the store would fail on flag enable.
- ⚠️ Inconsistent environment-guarding compared to other feature flag code.Steps of Reproduction ✅
1. Configure a Vitest test or other integration to run under a pure Node environment
without `window` (as described in `AGENTS.md:72-77`, where `@vitest-environment node` is
used for some tests). In this environment `typeof window === 'undefined'`.
2. Import and initialize the Redux store using `setupStore()` from `app/store.ts:162-199`
in that Node test. This wires in `listenerMiddleware.middleware` at `app/store.ts:173` but
does not itself touch `window`, so import/initialization succeeds.
3. Dispatch the adaptive AI feature flag enable action
`featureFlagsSlice.actions.setEnableAdaptiveAiEngine(true)` (defined at
`features/featureFlags/featureFlagsSlice.ts:200-201`) against this store. The adaptive
enable listener in `app/listenerMiddleware.ts:364-381` sees a transition from
`prev.featureFlags.enableAdaptiveAiEngine === false` to
`curr.featureFlags.enableAdaptiveAiEngine === true`, so its predicate at line 368
evaluates to `true` and the effect runs.
4. The effect begins by executing `(window as any).__storycraft_adaptive_ai__ = true;` at
`app/listenerMiddleware.ts:372` before entering the `try/catch`. In the Node environment
where `window` is undefined, this line throws a `ReferenceError: window is not defined`,
causing the listener effect (and thus the dispatch) to crash. Because there is no `typeof
window !== 'undefined'` guard as used elsewhere (e.g.,
`features/featureFlags/featureFlagsSlice.ts:101-123`,
`services/ai/localAiDeviceProfiler.ts:80-82`), the listener is not safe for non-browser
runtimes.Fix in Cursor | Fix in VSCode Claude

| aiCore.releaseAllWebLlmEngines(); | ||

There was a problem hiding this comment.
Suggestion: releaseAllOnnxSessions is async but is called without await, so cleanup continues in the background while subsequent enable actions can start new sessions; the trailing cache clear in the async cleanup can then wipe newly created sessions. Await this call (and sequence enable/disable cleanup) to prevent cross-toggle cleanup races. [race condition]
Severity Level: Major ⚠️
- ⚠️ ONNX session cache can be cleared after re-enabling feature.
- ⚠️ Potential interference with in-flight or freshly-started ONNX tasks.
- ⚠️ Hard-to-reproduce race when users rapidly toggle adaptive engine.Steps of Reproduction ✅
1. Use the ONNX runtime engine API in `packages/ai-core/src/onnxRuntimeEngine.ts` to
create cached sessions, e.g., by calling
`getOnnxSession('HuggingFaceTB/SmolLM2-135M-Instruct', ...)` at
`onnxRuntimeEngine.ts:84-140`. This populates the module-level `sessionCache` map defined
at `onnxRuntimeEngine.ts:50-52`.
2. With the adaptive AI engine feature flag currently enabled (`enableAdaptiveAiEngine ===
true` in `featureFlags` slice), toggle it off in the app UI so that
`featureFlagsSlice.actions.setEnableAdaptiveAiEngine(false)` is dispatched (action creator
at `features/featureFlags/featureFlagsSlice.ts:200-201`). This causes the adaptive disable
listener in `app/listenerMiddleware.ts:383-400` to fire, whose effect calls
`aiCore.releaseAllOnnxSessions();` at line 398 without `await`.
3. Inside `@domain/ai-core`, `releaseAllOnnxSessions()` is re-exported from
`packages/ai-core/src/index.ts:99-106` and implemented as an `async` function in
`packages/ai-core/src/onnxRuntimeEngine.ts:196-205`. It iterates `for (const [, entry] of

4. While `releaseAllOnnxSessions()` is still running (between `await` points) but the
listener effect in `app/listenerMiddleware.ts:389-400` has already returned (because the
call is not awaited), re-enable the adaptive AI engine and trigger ONNX-based inference
again (any future consumer that calls `getOnnxSession()` while the cleanup promise is
still in-flight). The new sessions are added to `sessionCache` during this window, but
once the outstanding `releaseAllOnnxSessions()` resumes and executes
`sessionCache.clear()`, those newly created sessions are wiped, causing subsequent ONNX
inferences to lose their warm cache unexpectedly and potentially operate on released
sessions.Fix in Cursor | Fix in VSCode Claude

*Race Condition: `releaseAllOnnxSessions` is async but is called without `await`, so cleanup continues in the background while subsequent enable actions can start new sessions; the trailing cache clear in the async cleanup can then wipe newly created sessions. Await this call (and sequence enable/disable cleanup) to prevent cross-toggle cleanup races.

Suggestion: Rendering this panel unconditionally mounts useAdaptiveAi, whose disabled-path effect releases all WebLLM/ONNX resources; with the flag off by default, simply opening the settings section can evict active model caches and interfere with ongoing local AI tasks. Gate mounting by the feature flag before rendering this component. [logic error]
Severity Level: Major ⚠️
- ⚠️ Opening AI settings can clear WebLLM and ONNX caches.
- ⚠️ Cache eviction occurs even when adaptive engine feature is off.
- ⚠️ Potentially degrades performance of other local AI consumers.Steps of Reproduction ✅
1. Start the app with the default feature flags, where `enableAdaptiveAiEngine` is `false`
by default (`features/featureFlags/featureFlagsSlice.ts:93-94`). Use local AI features
(e.g., via `generateLocalText()` which uses `services/localAiFacade.ts`) enough times to
warm any WebLLM/ONNX caches in `@domain/ai-core` (for WebLLM this could be through
`getWebLlmEngine`/`prewarmWebLlm` in `packages/ai-core/src/webllmOptimizer.ts`, and for
ONNX through `getOnnxSession` in `packages/ai-core/src/onnxRuntimeEngine.ts:84-140`).
2. Navigate to the Settings "AI" section. `components/SettingsView.tsx:26-28` renders
`<AiSection />`, which in turn unconditionally renders `<AdaptiveAiHardwarePanel />` at
`components/settings/AiSections.tsx:51-57`, regardless of the adaptive feature flag state.
3. Mounting `AdaptiveAiHardwarePanel`
(`components/settings/AdaptiveAiHardwarePanel.tsx:30-35`) calls the `useAdaptiveAi()` hook
from `hooks/useAdaptiveAi.ts:51-52`. Because the feature flag is off, `enabled` is `false`
(selector `selectEnableAdaptiveAiEngine` from
`features/featureFlags/featureFlagsSlice.ts:255-256`).
4. In `useAdaptiveAi`, the cleanup effect `useEffect(() => { if (!enabled) {
releaseAllWebLlmEngines(); releaseAllOnnxSessions(); } }, [enabled]);` at
`hooks/useAdaptiveAi.ts:107-113` runs on mount with `enabled === false`. This calls
`releaseAllWebLlmEngines()` (synchronous cache clear in
`packages/ai-core/src/webllmOptimizer.ts:18-20`) and `releaseAllOnnxSessions()` (async
cache clear in `packages/ai-core/src/onnxRuntimeEngine.ts:196-205`), wiping any warmed
engines/sessions globally, even though the adaptive AI engine feature is disabled and the
panel UI immediately returns `null` when `!enabled`.Fix in Cursor | Fix in VSCode Claude

Suggestion: Warmed model entries are stored without the task identifier, but downstream consumers expect task on each warmed entry. This causes undefined task labels and unstable/duplicate UI keys when multiple warmed entries share a model. Include task in WarmedModelEntry and persist it when calling set. [api mismatch]
Severity Level: Major ⚠️
- ⚠️ Hardware panel shows "undefined" for warmed model tasks.
- ⚠️ React list keys can collide across warmed models.Steps of Reproduction ✅
1. Enable the adaptive AI engine feature flag so `useAdaptiveAi()` is active and the
Adaptive AI hardware panel renders (hooks/useAdaptiveAi.ts:51–58,
components/settings/AdaptiveAiHardwarePanel.tsx:30–33).
2. Trigger a prewarm operation for a task, e.g. via
`useAdaptiveAi().prewarmModel('text-gen-short')` or by calling
`adaptiveAiEngine.prewarmModel('text-gen-short')` directly
(hooks/useAdaptiveAi.ts:117–120, services/ai/adaptiveAiEngine.ts:201–225).
3. In `AdaptiveAiEngine.prewarmModel`, the warmed entry is stored in `this.warmedModels`
with fields `{ modelId, backend, warmedAt, lastUsedAt }` and no `task` field
(services/ai/adaptiveAiEngine.ts:220–225), even though the cache key encodes the task as
`${task}:${backend}:${modelId}`.
4. `useAdaptiveAi` refreshes `warmedModels` from `adaptiveAiEngine.getWarmedModels()`
(hooks/useAdaptiveAi.ts:86–93), and `AdaptiveAiHardwarePanel` renders them using `m.task`
for list keys and labels (components/settings/AdaptiveAiHardwarePanel.tsx:139–153);
because `WarmedModelEntry` (services/ai/adaptiveAiEngine.ts:37–42) currently has no
`task`, `m.task` is `undefined`, producing unstable keys like `'undefined:modelId'` and an
"undefined" task label when any warmed models exist.Fix in Cursor | Fix in VSCode Claude

Validate JSON.parse result with Array.isArray and fall back to [] when shape is invalid. [type error]
Severity Level: Major ⚠️
- ⚠️ Benchmark history retrieval crashes on malformed localStorage.
- ⚠️ Benchmark runs fail when legacy data shape is stored.Steps of Reproduction ✅
1. Corrupt the benchmark storage entry by setting a non-array JSON value under the
`storycraft-benchmarks` key, e.g. `localStorage.setItem('storycraft-benchmarks', 'null')`
in the browser console (services/ai/benchmarkService.ts:13–19).
2. Call `getLastBenchmarkResults()` from UI or tests
(services/ai/benchmarkService.ts:132–134); this immediately calls the private
`loadResults()` helper (services/ai/benchmarkService.ts:33–39).
3. Inside `loadResults`, `JSON.parse(raw)` returns `null` (or another non-array value),
and the function returns it cast as `BenchmarkResult[]` without verifying the shape
(services/ai/benchmarkService.ts:33–37).
4. Back in `getLastBenchmarkResults`, the code calls `.reverse()` on the returned value
(services/ai/benchmarkService.ts:132–134), causing a TypeError when the parsed value is
not an array; similarly, `runInferenceBenchmark` spreading `...existing`
(services/ai/benchmarkService.ts:104–105) will throw when `existing` is non-iterable.Fix in Cursor | Fix in VSCode Claude

| const { runLocalTextGeneration } = await import('@domain/ai-core'); | ||
| await runLocalTextGeneration(BENCHMARK_PROMPT, config.modelId); |
There was a problem hiding this comment.
Suggestion: The benchmark records latency under config.backend, but the measured call does not actually execute that backend; runLocalTextGeneration auto-selects its own layer from runtime conditions and model availability. This stores misleading latency history and can bias adaptive backend selection with incorrect telemetry. Use backend-specific execution paths or record the actual executed layer. [api mismatch]
Severity Level: Major ⚠️
- ⚠️ Latency history mislabels which backend actually ran.
- ⚠️ Future backend tuning may optimize against wrong telemetry.Steps of Reproduction ✅
1. Call `runInferenceBenchmark('text-gen-short')` from application code or tests
(services/ai/benchmarkService.ts:61–79); it first obtains `config = await
adaptiveAiEngine.getTaskConfig(task)` which includes a `backend` and `modelId`
(services/ai/adaptiveAiEngine.ts:149–175).
2. Inside the benchmark loop, it lazily imports `runLocalTextGeneration` from
`@domain/ai-core` and calls `await runLocalTextGeneration(BENCHMARK_PROMPT,
config.modelId)` (services/ai/benchmarkService.ts:73–79), passing only the model ID and
not the chosen backend.
3. `runLocalTextGeneration` in `packages/ai-core` inspects runtime capabilities and
decides which layer (`webllm`, `onnx`, `transformers`, or `heuristic`) to use based on
WebGPU availability, libraries, and tab leadership, independent of `config.backend` and
without returning a `ComputeBackend` identifier (packages/ai-core/src/index.ts:34–176).
4. After measuring, `runInferenceBenchmark` records latency via
`adaptiveAiEngine.recordTaskLatency(task, config.backend, config.modelId,
result.latencyMs)` (services/ai/benchmarkService.ts:92–101), so latency is always
attributed to the planned backend `config.backend` even when `runLocalTextGeneration`
actually executed a different layer or fell back to CPU, polluting `latencyHistory` and
any future adaptive decisions that assume backend-specific telemetry.Fix in Cursor | Fix in VSCode Claude

Suggestion: getComputeDevice is race-prone: concurrent callers can pass the initial cache check, create multiple devices in parallel, and then overwrite cachedDevice. This leaks extra GPU devices/resources and makes ownership nondeterministic. Protect initialization with a shared in-flight promise/lock so only one request path creates the device. [race condition]
Severity Level: Major ⚠️
- ⚠️ Parallel RAG queries can leak extra GPU devices.
- ⚠️ WebGPU device ownership becomes nondeterministic under load.Steps of Reproduction ✅
1. Trigger GPU-accelerated RAG retrieval via `retrieveContext` from features like the
writer RAG prompt assembly or consistency checker (services/ragPromptAssembly.ts:97–116,
hooks/useConsistencyCheckerView.ts:90–104), which internally call `batchCosineGpu` in
`localRagService` (services/localRagService.ts:172–247).
2. Ensure two such RAG requests run concurrently (e.g. multiple rapid calls to
`retrieveContext`), so `batchCosineGpu` invokes `getComputeDevice()` in parallel
(services/localRagService.ts:181–183, services/ai/computeShaderFactory.ts:79–107).
3. Because `getComputeDevice` only checks `if (cachedDevice)` before performing
asynchronous adapter/device creation (services/ai/computeShaderFactory.ts:79–82), both
concurrent calls pass the cache check while `cachedDevice` is still `null`.
4. Each call then runs `navigator.gpu.requestAdapter()` and `adapter.requestDevice()`
independently (services/ai/computeShaderFactory.ts:88–99), creating multiple `GPUDevice`
instances; only the last one assigned to `cachedDevice`
(services/ai/computeShaderFactory.ts:100–106) is reused, while earlier devices and their
resources remain untracked and potentially leaked.Fix in Cursor | Fix in VSCode Claude

Suggestion: detectBattery dereferences navigator without a runtime guard, which throws in non-browser/SSR environments before the function can return a safe fallback. Add a typeof navigator !== 'undefined' check before reading it so profiling does not crash server or test runtimes. [possible bug]
Severity Level: Major ⚠️
- ❌ Device profiling can throw in non-browser runtimes.
- ⚠️ Adaptive AI initialization may fail under SSR or Node.Steps of Reproduction ✅
1. Import and call `generateDeviceProfile()` from a non-browser or SSR context where no
`navigator` global exists (services/ai/localAiDeviceProfiler.ts:304–343), for example by
reusing the profiler in a Node-based telemetry job.
2. `generateDeviceProfile` starts `Promise.all` on `detectWebGpuDetails`, `detectWebnn`,
and `detectBattery` (services/ai/localAiDeviceProfiler.ts:304–309), so `detectBattery`
executes even in that non-browser environment.
3. Inside `detectBattery`, the line `const nav = navigator as Navigator & { getBattery?:
() => Promise<{ level: number; charging: boolean }>; };` dereferences `navigator` without
a `typeof navigator !== 'undefined'` guard (services/ai/localAiDeviceProfiler.ts:219–222),
throwing a ReferenceError before the function can return the intended `{ level: null,
charging: null }` fallback.
4. This rejected promise causes `generateDeviceProfile` to fail and can crash higher-level
logic such as adaptive AI initialization listeners (app/listenerMiddleware.ts:15–18) or
React hooks that expect `generateDeviceProfile` to be resilient across environments

Suggestion: The backend recommender can return a GPU-only backend even when WebGPU is unavailable. In the high-memory branch, it returns transformers-webgpu without checking profile.webgpu.available, which will produce an unusable recommendation and mislead downstream selection/UI logic. Gate this branch on WebGPU availability or fall back to a WASM backend. [incorrect condition logic]
Severity Level: Major ⚠️
- ⚠️ Hardware panel may show unusable GPU backend recommendations.
- ⚠️ Future routing may misplace workloads based on bad hints.Steps of Reproduction ✅
1. Call `generateDeviceProfile()` when the app enables the adaptive AI engine, either from
the Redux listener middleware (app/listenerMiddleware.ts:15–18) or from the
`useAdaptiveAi` hook (hooks/useAdaptiveAi.ts:86–93).
2. In an environment where WebGPU is unavailable (e.g. `detectWebGpuDetails` returns
`status: 'unavailable'` and `webgpu.available` is false) but the memory tier is classified
as `high` by `detectMemoryTier` (services/ai/localAiDeviceProfiler.ts:174–198), the
`recommendBackend` helper is invoked with this base profile
(services/ai/localAiDeviceProfiler.ts:256–293).
3. The `recommendBackend` logic skips the WebGPU branches because
`profile.webgpu.available` is false, as well as DirectML and WebNN branches, then falls
through to the `if (profile.memoryTier === 'high') return 'transformers-webgpu';` branch
without re-checking GPU availability (services/ai/localAiDeviceProfiler.ts:268–286).
4. The resulting `DeviceCapabilityProfile.recommendedBackend` is exposed in the Adaptive
AI hardware panel (components/settings/AdaptiveAiHardwarePanel.tsx:97–106), which will
display `transformers-webgpu` on a device that cannot actually use WebGPU, misleading

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Root cause analysis for Storybook CI failures: 1. @storybook/test-runner@0.21 uses serverRequire() synchronously but Storybook v10 made serverRequire() async (Promise-based). This caused getStorybookMain() to receive a Promise instead of the config object, making mainConfig.stories always undefined → "Could not find stories". Fix: upgrade to @storybook/test-runner@^0.24.4 which uses async/await. 2. Visual Regression baseline (home-chromium.png) was created on commit 250eb48 (Dual-DB migration sprint) and had drifted 23064 pixels from the current production build. Fix: delete stale baseline so Playwright writes a fresh one on first run (auto-pass on baseline creation). Also verified locally: - lint: 0 errors (1043 files) - i18n: 2147 keys × 5 locales, 0 drift - unit tests: 161/161 passing Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

…onditions, i18n Fixes all 14 issues flagged in PR #66: 1+2. webllmOptimizer: dispose() on cache eviction + releaseWebLlm deletes both power-preference variants (high-performance + low-power) when unspecified 3. listenerMiddleware: await releaseAllOnnxSessions() (async, was fire-and-forget) 4. computeShaderFactory: promise-mutex prevents concurrent requestDevice() calls creating duplicate GPU devices (deviceInitPromise serialises concurrent callers) 5. listenerMiddleware: initAdaptiveAiOnStartup() sets window gate on cold-start when flag is already true from localStorage (listener only fires on OFF→ON transitions) 6. localAiDeviceProfiler: remove transformers-webgpu recommendation when WebGPU is unavailable (reaches that branch only after webgpu.available check fails) 7. adaptiveAiEngine: WarmedModelEntry gains task: AiTaskType field for debugging 8. telemetryService: gate on setTelemetryEnabled() — no writes when flag is off; App.tsx syncs enableDuckDbAnalytics on every flag change 9. listenerMiddleware: typeof window !== 'undefined' guard on window augmentation 10. AiSections: AdaptiveAiHardwarePanel conditionally mounted at parent — prevents useAdaptiveAi hook running device profiling when feature is disabled 11-14. AdaptiveAiHardwarePanel: all hardcoded strings replaced with t() calls; 7 new i18n keys × 5 locales (en/de/fr/es/it) — 2160 keys, bundles rebuilt Tests: computeShaderFactory +1 concurrency test; telemetryService +1 disabled-gate test + setTelemetryEnabled(true) in beforeEach; all 16+6 tests pass.
