PR Summary:

Enhanced LLM-Based Failure Analysis System — adds failure-pattern retrieval, persistent storage, analytics, UI, and E2E tests; converts Graphiti memory usage to async.

• Overview

  • Introduces end-to-end failure analysis workflow: extract root causes, persist them in Graphiti, surface past failure patterns to QA fixer, and show metrics in the frontend.
  • Adds robust tracking and dashboard surfaces for failure patterns and trends.

• Key backend changes

  • apps/backend/agents/memory_manager.py
    • Many calls to get_graphiti_memory are now awaited (async).
    • Adds async get_failure_patterns(...) to query Graphiti for root-cause episodes, filter/format results, and return a human-readable failure-pattern summary.
    • Ensures memory connections are closed with await memory.close().
  • apps/backend/analysis/failure_storage.py (new)
    • New async module to persist failure analyses and QA results to Graphiti.
    • Public API: store_failure_analysis(...) and store_qa_result(...); internal helpers add episodes and update memory state.
    • Graceful no-op when Graphiti is disabled; error capture via Sentry.
  • apps/backend/analysis/failure_analyzer.py
    • Expanded heuristics: broader patterns for test failures and new build_error category (more detection keywords and recommendations).
    • Slight description and recommendations updates (e.g., test setup/teardown, build tooling).
  • apps/backend/analysis/metrics_tracker.py
    • Adds failure-pattern tracking: get_failure_metrics(...) calculating failure counts, types, recurrence, top files/categories, pattern detection rate, etc.
    • Integrates failure metrics into get_detailed_metrics().
  • apps/backend/qa/fixer.py
    • Imports and uses get_failure_patterns(...) to include prior failure analyses in QA fixer prompts.
    • Avoids double-reading fix_request_content; reuses loaded content.
  • apps/backend/qa/loop.py
    • Calls new store_failure_analysis(...) to persist analyzed QA rejections; logs success/failure of storing.
    • Changed memory usage to async-compatible flows where needed.

• Frontend changes

  • apps/frontend/src/shared/types/productivity-analytics.ts
    • Adds FailureMetrics and related types for frontend usage.
  • New UI components:
    • FailureAnalysisDashboard.tsx — 7-day trend chart and summary for failures, root-cause and recurrence trends.
    • FailurePatternsCard.tsx — cards showing pattern stats and top categories.
  • ProductivityDashboard.tsx
    • Integrates FailureAnalysisDashboard and new failureMetrics state placeholders.

• Tests

  • tests/integration/test_failure_analysis_e2e.py (new)
    • End-to-end integration tests covering QA rejection -> analysis -> storage -> retrieval by fixer -> dashboard metrics -> learning improvement.
    • Mocks Graphiti where needed and verifies graceful degradation when disabled.

• Behavior & compatibility notes

  • Graphiti interactions are now consistently async — callers must await get_graphiti_memory and respect async APIs. Code in this PR has been updated accordingly, but external integrations or other modules may need updates if they call those helpers synchronously.
  • All Graphiti persistence calls gracefully no-op when Graphiti is disabled; added logging and Sentry capture on errors.
  • New Graphiti storage increases network/IO operations; may add latency to QA loop/fixer flows (but enables learning across sessions).

• Misc

  • No external dependency bumps in diffs; new Graphiti usage relies on existing integrations.
  • Emphasis on safe failure modes: if memory/Graphiti unavailable, system logs and continues without failing the user-facing flows.

[CRITICAL_BUG] get_failure_patterns(): several issues that can cause incorrect/missing results or brittle behavior:

1. Uses private API memory._client.graphiti.search (lines ~369-373). Other code in this repo uses the public client/property (e.g. memory.client) or higher-level memory methods (see memory_manager reference around lines 175-205 where pattern_suggester is called with client=memory.client). Accessing _client is brittle and may break if GraphitiMemory internals change — use the documented public API (memory.client or memory.search helper) or provide a safe accessor.

2. The function checks EPISODE_TYPE_ROOT_CAUSE by doing a string membership test on content (line ~398) before decoding/parsing. This is fragile: content may be a dict, a JSON string, or other shape. Instead, parse JSON (or coerce mapping) first, then check data.get('type') == EPISODE_TYPE_ROOT_CAUSE. Relying on str(content) can miss matches and cause false negatives.

3. json is imported inside the loop (line ~400). Move the import to the top of the function/module to avoid repeated imports and clarify dependencies.

4. result handling assumes attributes (result.content / result.fact / result.score). Normalize handling to support both attribute-access objects and mapping results (try getattr then fallback to result.get(...) if result is a dict) to avoid AttributeError and to be resilient to different client SDK return types.

5. Consider limiting use of private fields on memory (e.g. memory._client) and ensure all calls that use network/IO are behind try/except and respect memory lifecycle (initialize/close). You already await memory.close() in finally — good — but ensure any client usage is via stable public surfaces.

Please update the function to parse content before inspecting its 'type', use the public client API, import json once, and make result parsing robust to both dicts and objects.

[REFACTORING] You added many new substring patterns for test and build errors. To make matching reliable and maintainable:

1. Ensure error_text is normalized (lowercased and trimmed) before running these 'pattern in error_text' checks. If extract_root_cause doesn't already lower-case the composed error_text, add error_text = error_text.lower() before the series of any(...) checks.

2. Consider grouping/ordering patterns to avoid misclassification (e.g., 'eslint'/'pylint' are linter issues — keep them in a build/lint category but ensure they don't conflict with test failure matches like 'coverage threshold').

3. Put the pattern lists in named constants (TEST_PATTERNS, BUILD_PATTERNS) or a config so they are easier to maintain and unit test.

This will reduce false negatives/positives and make the logic easier to extend.

[CRITICAL_BUG] store_failure_analysis() and store_qa_result(): get_graphiti_memory is invoked synchronously (lines ~86 and ~153) but elsewhere the helper is async and must be awaited (see session_context.initialize and recent memory_manager changes). Calling it without await will return a coroutine or fail at runtime. Change to: memory = await get_graphiti_memory(spec_dir, project_dir, group_id_mode) and then defensively check 'if memory is None:' before accessing memory.is_enabled or memory.is_initialized. Also ensure you close the memory client in a finally block (await memory.close()) to avoid leaking connections; wrap usage in try/finally to guarantee resource cleanup.

Additionally, check memory.is_enabled only after verifying memory is not None to avoid AttributeError.

[CRITICAL_BUG] _store_root_cause_episode() and _store_qa_result_episode() directly use memory._client.graphiti.add_episode (lines ~231 and ~302). This accesses an internal/private attribute and bypasses higher-level helpers; it is brittle and can break if GraphitiMemory internals change. Prefer the public API on memory (for example memory.client or the provided memory.save_session_insights/add_episode wrapper) or reuse existing memory methods such as memory.save_session_insights/save_structured_insights used elsewhere (see memory_manager references around lines 544-580). Also:

• Validate that the Graphiti client call returns/raises in a way you expect and handle failures explicitly.
• Make sure episode_body content is validated (e.g. ensure JSON is serializable and not too large) and avoid using memory internals like _client.

Refactor these helpers to call a documented public method on memory or add a small adaptor in memory.graphiti_helpers to expose add_episode safely.

[CRITICAL_BUG] metrics may be None here — _load_learning_metrics(spec_dir) can return None which will make metrics.get(...) raise an AttributeError.

[REFACTORING] Date label keys are constructed as key={date-label-${label}-${x}} (uses label plus a computed float x). That leads to unstable keys when layout/scaling changes and can force unnecessary DOM remounts. Use a stable key (e.g., the ISO date string from trends[index].date or the index if you guarantee order) instead of including a float x.

{/* Date labels */}
{chartData.dateLabels.map((label, index) => {
  const x =
    chartData.padding.left +
    (index / (chartData.dateLabels.length - 1 || 1)) * chartData.chartWidth;

  return (
    <text
      key={`date-label-${trends[index]?.date ?? label}`}
      x={x}
      y={chartData.height - chartData.padding.bottom + 20}
      textAnchor="middle"

[REFACTORING] The expression (trends.length - 1 || 1) (used at line 93 and again at line 329) relies on JavaScript truthiness of numeric subtraction to avoid division by zero. This works but is hard to read. Extract an explicit denominator variable, e.g. const denom = trends.length > 1 ? trends.length - 1 : 1; and use index / denom. That is clearer and less error prone.

// When computing x positions
const denom = trends.length > 1 ? trends.length - 1 : 1;

const points = trends.map((point, index) => {
  const x = padding.left + (index / denom) * chartWidth;
  const value = point[metric.key] as number;
  const y =
    padding.top +
    chartHeight -
    ((value - minValue) / range) * chartHeight;
  return { x, y, value };
});

// ... later for date labels
const labelDenom = chartData.dateLabels.length > 1
  ? chartData.dateLabels.length - 1
  : 1;

{chartData.dateLabels.map((label, index) => {
  const x =
    chartData.padding.left + (index / labelDenom) * chartData.chartWidth;
  return (
    <text
      key={`date-label-${trends[index]?.date ?? label}`}

[VALIDATION] The new FailureMetrics interface defines many required fields (root_cause_rate, recurrence_rate, top_failure_categories, etc.). In practice backend payloads can be partial or some fields may be omitted. Consider making fields that may be missing optional (e.g., root_cause_rate?: number) or provide a runtime validator/default mapper when constructing FailureMetrics to avoid runtime undefined access leading to UI NaNs or crashes. Document expected ranges (0-1) in comments or use stricter branded types if needed.

// In apps/frontend/src/shared/types/productivity-analytics.ts

export interface FailureMetrics {
  total_failures: number;
  failure_types: Record<string, number>;  // Count by type (qa_rejection, build_error, etc.)
  failure_categories: Record<string, number>;  // Count by category
  root_causes_identified: number;
  /** Proportion of failures with an identified root cause (0.0 - 1.0) */
  root_cause_rate: number;  // 0.0 - 1.0
  recurring_failures: number;
  /** Proportion of failures that are recurring (0.0 - 1.0) */
  recurrence_rate: number;  // 0.0 - 1.0
  top_failure_files: FailureFileCount[];  // Top 5 files with most issues
  top_failure_categories: FailureCategoryCount[];  // Top 5 categories
  /** Proportion of issues with detected patterns or suggested fixes (0.0 - 1.0) */
  pattern_detection_rate: number;  // Issues with detected patterns / total
  avg_occurrences_per_failure: number;
}

// Example of a safer consumer in FailureAnalysisDashboard
// apps/frontend/src/renderer/components/analytics/FailureAnalysisDashboard.tsx

export function FailureAnalysisDashboard({ failureMetrics, isLoading = false }: FailureAnalysisDashboardProps) {
  const safeMetrics: FailureMetrics | null = failureMetrics
    ? {
        total_failures: failureMetrics.total_failures ?? 0,
        failure_types: failureMetrics.failure_types ?? {},
        failure_categories: failureMetrics.failure_categories ?? {},
        root_causes_identified: failureMetrics.root_causes_identified ?? 0,

[CRITICAL_BUG] The test patches analysis.failure_analyzer.is_analysis_enabled (lines 174-176) but then calls analyze_failure(...) (lines 176-181). In failure_analyzer.analyze_failure the code always calls extract_root_cause(..., use_llm=True) (see failure_analyzer.py lines 598-628). Patching is_analysis_enabled will not disable LLM usage inside analyze_failure, so this test is asserting a behavior that won't be affected by the patch and may give false confidence. Actionable fixes: (a) If you want to force heuristic-only behavior, patch analysis.failure_analyzer.extract_root_cause to a stub that simulates heuristic output, or (b) add a parameter to analyze_failure to control use_llm (or expose a public toggle that analyze_failure respects) and call it from the test, or (c) call extract_root_cause(use_llm=False) directly (already used earlier) instead of analyze_failure. Prefer patching extract_root_cause or changing analyze_failure to accept a use_llm flag so tests can reliably control LLM behavior.

# In tests/integration/test_failure_analysis_e2e.py
# Replace the is_analysis_enabled patch block with an extract_root_cause-focused check,
# so the test isn't assuming analyze_failure respects the toggle.

from analysis.failure_analyzer import analyze_failure, extract_root_cause

# ... existing heuristic assertions above ...

# Instead of patching is_analysis_enabled (which analyze_failure ignores for use_llm):
analysis = analyze_failure(
    test_spec_dir,
    test_project_dir,
    "qa_rejection",
    failure_context,
)

[REFACTORING] In test_6 you compute initial_failures and then assert metrics_after['total_failures'] >= initial_failures (lines 440-466). This is confusing for a test titled 'Verify Success Rate Improves' — if the system "learns" you'd expect failure rate (failures per iteration) or failures per-some-window to decrease, not necessarily cumulative totals to go down. Replace the cumulative comparison with a metric that reflects improvement, e.g. compare failure_rate_before = total_failures_before / iterations_before and failure_rate_after = total_failures_after / iterations_after and assert failure_rate_after <= failure_rate_before (or assert that failures_per_iteration decreased). Alternatively assert approved rate increased. This will make the test assert the intended learning behavior rather than an ambiguous cumulative count.

# In tests/integration/test_failure_analysis_e2e.py, inside test_6_success_rate_improves

metrics_before = get_failure_metrics(test_spec_dir)
initial_failures = metrics_before["total_failures"]

# ... mutate plan and write back ...

metrics_after = get_failure_metrics(test_spec_dir)

# Compare failures per iteration instead of raw cumulative counts
iterations_before = 1
iterations_after = len(plan["qa_iteration_history"])

failure_rate_before = initial_failures / iterations_before
failure_rate_after = metrics_after["total_failures"] / iterations_after

assert failure_rate_after <= failure_rate_before

[REFACTORING] test_e2e_complete_flow directly calls other test_xxx functions (lines 504-510). Calling pytest test functions from another test is brittle and bypasses pytest's normal fixture resolution/lifecycle and reporting. Refactor by extracting the shared logic into helper functions (e.g., _create_qa_rejection, _run_failure_analysis, _store_and_verify_graphiti, etc.) and have both the individual tests and the end-to-end orchestrator call those helpers. That keeps tests composable and avoids nesting test calls.

# In tests/integration/test_failure_analysis_e2e.py

# Extract shared flows into helpers:

async def _run_trigger_qa_rejection(spec_dir, project_dir):
    await test_1_trigger_qa_rejection(spec_dir, project_dir)

# ... similarly extract helpers for each logical step ...

    print("=" * 70 + "\n")

[NITPICK] Remove the main block (lines 526-529) from an integration test module. Tests should be executed via pytest/CI; the main runner is unnecessary and can confuse test discovery or duplicate execution behavior. If you want local convenience, consider a small dedicated script or use pytest -k to run the test module.

# In tests/integration/test_failure_analysis_e2e.py

# Remove this __main__ block entirely:
if __name__ == "__main__":

Tooltips use `metric.formatValue(point.value)` but CHART_METRICS.formatValue for percent rates returns a plain numeric string (e.g., '12.3') while other places append '%' (e.g., stats use `(rate * 100).toFixed(1) + '%'`). Make the tooltip formatting consistent — either have formatValue include units (e.g., '12.3%') for percentage metrics or append the unit when rendering the tooltip.

In test_4 you define mock_get_memory as async def mock_get_memory(...) and use it as side_effect for patch('agents.memory_manager.get_graphiti_memory', side_effect=mock_get_memory). The memory_manager code sometimes calls get_graphiti_memory synchronously (no await) and sometimes awaits it (see apps/backend/agents/memory_manager.py lines 175-205 and 324-354). Make the mock match the actual usage in agents.memory_manager.get_graphiti_memory: if the real helper is synchronous in this context, use a normal def that returns mock_memory_instance; if it is awaited, use AsyncMock/async def. To avoid ambiguity, patch the exact attribute used in the function under test (module-local name) and ensure return value implements both sync and async behavior if necessary (e.g., provide an object and also an awaitable wrapper).

# In tests/integration/test_failure_analysis_e2e.py, inside test_4_qa_fixer_retrieves_patterns

When verifying that an async Graphiti method was called you assert mock_memory_instance._client.graphiti.add_episode.called (line 270). For AsyncMock you should assert the coroutine was awaited using assert_awaited or assert_awaited_once (e.g., mock_memory_instance._client.graphiti.add_episode.assert_awaited()). This gives stronger guarantees that the async call actually executed and awaited as expected.

# In tests/integration/test_failure_analysis_e2e.py, inside test_3_failure_stored_in_graphiti

# After calling store_failure_analysis(...):

assert result is True
mock_memory_instance._client.graphiti.add_episode.assert_awaited()

Others

- Verify the newly imported function store_failure_analysis (analysis.failure_storage) has robust behavior when Graphiti is disabled/unavailable: it should return False (not raise) and avoid failing the QA loop. The code treats the function's returned 'stored' boolean but still relies on analyze_failure producing a 'root_cause' dict — ensure analyze_failure always returns a dict (or callers defensively handle None).

# In analysis/failure_storage.py
async def store_failure_analysis(
    spec_dir: Path,
    project_dir: Path,
    failure_type: str,
    root_cause: dict[str, Any] | None,

) -> bool:
    # Normalize root_cause to avoid AttributeError in callers
    root_cause = root_cause or {}
    ...

Poem

🐰 A failing test, we now can trace,

In `@apps/backend/analysis/failure_analyzer.py`:
- Around line 44-78: CI reports formatting issues in the backend; run the code
formatter and commit the changes: run `ruff format apps/backend/ --fix` (or your
project's configured ruff command) to reformat files including the file defining
SYNTAX_ERROR_PATTERNS, MISSING_DEPENDENCY_PATTERNS, LOGIC_ERROR_PATTERNS,
TEST_ERROR_PATTERNS, BUILD_ERROR_PATTERNS, and TIMEOUT_PATTERNS, then review and
commit the updated formatting so the CI ruff check passes.

In `@apps/backend/analysis/failure_storage.py`:
- Around line 1-35: Run ruff format to fix style issues reported by CI for this
module: apply `ruff format` (or `ruff format apps/backend/ --fix`) to the
failure_storage.py file so imports, docstring, and spacing conform to the
project lint rules; ensure the top-level docstring and import block around
symbols like get_graphiti_memory, EPISODE_TYPE_QA_RESULT,
EPISODE_TYPE_ROOT_CAUSE, GroupIdMode, and logger are reformatted by ruff and
then re-run CI.
- Around line 245-331: In both _store_root_cause_episode and
_store_qa_result_episode, change the client lookup to prefer the private
attribute (use getattr(memory, "_client", None) or fallback to getattr(memory,
"client", None)) and validate that the resolved client has a usable graphiti
attribute (e.g., if client is None or not hasattr(client, "graphiti") or
client.graphiti is None, log/warn and return False) before awaiting
client.graphiti.add_episode; update both functions to perform this check to
avoid MagicMock/attribute errors in tests.

In
`@apps/frontend/src/renderer/components/analytics/FailureAnalysisDashboard.tsx`:
- Around line 24-218: The component FailureAnalysisDashboard currently contains
hardcoded user-facing strings (header, legend labels, loading/empty messages)
and a fixed date locale ('en-US'); replace these with i18n calls: import and use
the useTranslation hook inside FailureAnalysisDashboard, swap literal strings in
CHART_METRICS.label, the header "Failure Analysis Trends", loading text "Loading
failure analysis...", empty texts "No failure trend data available" and
"Complete more QA iterations to see failure trends", and legend/tooltips to
t('...') keys, and format dateLabels using date.toLocaleDateString(i18n.language
|| undefined, ...) or an i18n-aware date formatter; add the corresponding
translation keys to the locale files. Ensure CHART_METRICS, the header
rendering, the isLoading block, and the empty-state block use t(...) and that
dateLabels generation references i18n.language.

In `@apps/frontend/src/renderer/components/analytics/FailurePatternsCard.tsx`:
- Around line 117-189: The component currently uses hardcoded user-facing
strings in FailurePatternsCard (e.g., "Failure Patterns", the Badge count label,
"Loading failure analysis...", empty-state texts, StatCard labels "Total
Failures"/"Root Cause Rate"/"Pattern Detection"/"Recurrence Rate", and "Common
Failure Categories"); replace these with i18n keys using the useTranslation hook
(import and call const { t } = useTranslation()), use t('key') for each label
and message, and use pluralization/t interpolation for the failures count (e.g.,
t('failures', { count: stats.totalFailures })) so the Badge shows correct
singular/plural; update StatCard and CategoryItem prop usages to pass translated
labels and ensure any helper like formatPercentage is used with translated
suffixes if needed.

In `@apps/frontend/src/renderer/components/analytics/ProductivityDashboard.tsx`:
- Around line 31-32: The failureMetrics state is missing its setter and the data
isn't being loaded; update the state declaration to const [failureMetrics,
setFailureMetrics] = useState<FailureMetrics | null>(null) and then implement a
new electronAPI.getFailureMetrics IPC method (add it to the renderer electronAPI
interface and register a backend IPC handler) and call it from
loadAnalyticsData() to fetch the metrics and call setFailureMetrics(response)
(also handle errors and setIsLoading appropriately). Ensure the IPC channel name
matches between electronAPI.getFailureMetrics and the backend handler and that
loadAnalyticsData imports/uses electronAPI.getFailureMetrics to populate
failureMetrics.

In `@tests/integration/test_failure_analysis_e2e.py`:
- Around line 409-414: The failure-rate calculation currently divides
issues_after by total_iterations even though the intent (and the comment) is to
exclude approved iterations; update the calculation of failure_rate_after to use
rejected_iterations as the denominator (i.e., failure_rate_after = issues_after
/ rejected_iterations if rejected_iterations > 0 else 0.0) and ensure the
variables metrics_after, total_iterations, rejected_iterations, issues_after,
and failure_rate_after are used consistently.
- Around line 98-110: The mock _make_mock_graphiti_memory currently sets _client
as a MagicMock but store_failure_analysis prefers memory.client and awaits it,
causing "can't be used in 'await'". Make the client awaitable and exposed:
create mock_memory_instance._client as an AsyncMock (not MagicMock), attach
graphiti and graphiti.add_episode (AsyncMock) to it, and set
mock_memory_instance.client = mock_memory_instance._client so memory.client is
an awaitable alias; keep mock_memory_instance.close as AsyncMock.

Reorder client lookup to prefer _client and validate .graphiti before awaiting.

GraphitiMemory only exposes _client (set at line 70), not a public client property. The current fallback pattern getattr(memory, "client", None) or getattr(memory, "_client", None) works but relies on the second call succeeding. For test compatibility and clarity, prefer _client directly and validate the .graphiti attribute exists before awaiting to avoid MagicMock-related errors.

Apply to both episode helpers

-        client = getattr(memory, "client", None) or getattr(memory, "_client", None)
-        if client is None:
+        client = getattr(memory, "_client", None) or getattr(memory, "client", None)
+        graphiti = getattr(client, "graphiti", None) if client else None
+        if graphiti is None:
             logger.warning("No client available on memory instance")
             return False
-        await client.graphiti.add_episode(
+        await graphiti.add_episode(

Apply the same change in both _store_root_cause_episode and _store_qa_result_episode.

⚠️ Potential issue | 🟠 Major

Mock Graphiti memory needs an awaitable client to avoid CI failure.
store_failure_analysis() prefers memory.client first, so the current mock yields a non‑awaitable MagicMock, triggering “object MagicMock can't be used in 'await' expression” and the failing assertion in test_3. Expose a proper client alias in the mock.

Fix mock client wiring

 def _make_mock_graphiti_memory():
     ...
     mock_memory_instance._client = MagicMock()
     mock_memory_instance._client.graphiti = MagicMock()
     mock_memory_instance._client.graphiti.add_episode = AsyncMock()

Review Comments Addressed + Develop Merge

Merged latest develop into the PR branch, resolved conflicts, and addressed all review comments from pantoaibot, github-advanced-security, SonarCloud, and coderabbitai.

Merge Conflict Resolution

• ProductivityDashboard.tsx — kept both FailureAnalysisDashboard from this PR and new components (MetricsSummaryCard, TrendsChart, SpecBreakdownTable) from develop

Backend Fixes

• Private API access (pantoaibot, coderabbitai): Added public client property to GraphitiMemory, replaced all getattr(memory, "_client") patterns with memory.client
• ruff format: Auto-formatted failure_storage.py and failure_analyzer.py

Frontend Fixes

• i18n (coderabbitai): Added useTranslation to FailureAnalysisDashboard and FailurePatternsCard, replaced all hardcoded strings with translation keys (common:failureAnalysis.*, common:failurePatterns.*). Added EN + FR translations
• Unused variable (github-advanced-security): Replaced useState<FailureMetrics> with direct variable in ProductivityDashboard
• Optional fields (pantoaibot): Made FailureMetrics interface fields optional for partial backend payloads
• Unstable keys / unclear expression (pantoaibot): Already fixed in prior commit — verified denom variable and stable date-based keys

51-53: ⚠️ Potential issue | 🟠 Major

Failure metrics are never loaded, so the new dashboard is always empty.

failureMetrics is fixed to null, and the loader path never populates it, so FailureAnalysisDashboard cannot display real analytics.

Suggested wiring fix

-// TODO: Load from backend API when available
-const failureMetrics: FailureMetrics | null = null;
+const [failureMetrics, setFailureMetrics] = useState<FailureMetrics | null>(null);

-const [summaryResult, trendsResult] = await Promise.all([
+const [summaryResult, trendsResult, failureMetricsResult] = await Promise.all([
   withTimeout(window.electronAPI.getProductivitySummary(projectId, dateFilter)).catch(...),
   withTimeout(window.electronAPI.getProductivityTrends(projectId, dateFilter)).catch(...),
+  window.electronAPI?.getFailureMetrics
+    ? withTimeout(window.electronAPI.getFailureMetrics(projectId, dateFilter)).catch((err) => {
+        const msg = `FailureMetrics: ${err instanceof Error ? err.message : String(err)}`;
+        errors.push(msg);
+        return { success: false as const, error: msg, data: undefined };
+      })
+    : Promise.resolve({ success: true as const, data: null }),
 ]);

+if (failureMetricsResult.success) {
+  setFailureMetrics(failureMetricsResult.data ?? null);
+} else if (failureMetricsResult.error) {
+  errors.push(failureMetricsResult.error);

57-70: ⚠️ Potential issue | 🟠 Major

test_failure matching is currently too broad and can misclassify build/lint errors.

Using generic tokens like "expected"/"actual" in TEST_ERROR_PATTERNS plus evaluating that branch before build_error can route non-test failures into the wrong category.

Proposed tightening of pattern logic

     "test failed",

Await get_graphiti_memory(...) before using memory.

Dict-based search results are incorrectly filtered by score.

Line 406 reads score via getattr(...) only, so dict results default to 0.0 and fail min_score filtering even when they contain a valid score.

- Around line 49-74: The useMemo hook that creates synthetic trend data in
FailureAnalysisDashboard (the variable trends and the FailureTrendPoint
generation logic) must be removed; instead return real trend points from the
backend (e.g., use failureMetrics.trends or failureMetrics.trendPoints if the
API provides them) and if no backend series exist return an empty array so the
chart shows a no-data state; remove the heuristic loop and any math around
failureMetrics.total_failures, root_cause_rate, and recurrence_rate and wire the
chart to the backend trend array (or empty) so synthetic history is never
rendered.

In `@tests/integration/test_failure_analysis_e2e.py`:
- Around line 462-469: The test named test_2_failure_analyzed_with_llm is
misleading because _helper_failure_analyzed invokes extract_root_cause(...,
use_llm=False) and the helper patches extract_root_cause, so rename the test and
its docstring to reflect the non-LLM path (e.g.,
test_2_failure_analyzed_non_llm) or alternatively add a new true LLM-enabled
test that calls the helper (or a new helper variant) with use_llm=True and does
not patch extract_root_cause; locate test_2_failure_analyzed_with_llm in the
file, update the function name and docstring or add a new function like
test_2_failure_analyzed_with_llm that exercises extract_root_cause(use_llm=True)
(and remove/mutate the patching in that case) so coverage and names match
behavior.

SonarQube Fix Summary (commit 76a5ba9)

Addressed all SonarQube quality gate failures and review comments:

Duplication Fixes (was 5.3%, target ≤3%)

File	Before	Fix
failure_storage.py	Duplicated memory init/cleanup and client check patterns	Extracted _graphiti_session context manager + _add_episode helper
metrics_tracker.py	Empty failure metrics dict duplicated twice	Extracted _EMPTY_FAILURE_METRICS constant
FailureAnalysisDashboard.tsx	17.7% — 3 hardcoded summary cards + duplicated card shell	Data-driven summaryCards useMemo + single conditional render
FailurePatternsCard.tsx	21.5% — 4 StatCard invocations with identical shells	Data-driven statCards useMemo + mapped rendering

Reliability Fixes (was C, target ≥A)

• Null safety: values.length > 0 guard before Math.max/Math.min, Number(x) || 0 coercion, lastPoint null check
• Safe attribute access: getattr(memory, "spec_context_id", None) in failure_storage.py
• Score extraction: Handle dict results in memory_manager.py (getattr → dict .get() fallback)
• State persistence: Wrapped memory.state.save() in try-except

Review Comments Addressed

• Removed synthetic trend data from FailureAnalysisDashboard — trends is now a prop
• Renamed test_2_failure_analyzed_with_llm → test_2_failure_analyzed_non_llm (reflects non-LLM path)
• Fixed always-true condition in test_6: compute rejected_iterations from get_success_rate() instead of hardcoded 2
• Tightened TEST_ERROR_PATTERNS: replaced generic tokens with strict patterns, added re.search()
• Reordered dispatch: build_error now checked before test_failure
• Wired failureMetrics to backend API: full IPC pipeline (constant → type → preload → handler → browser mock → component)
• Verified get_graphiti_memory is synchronous (no change needed)

Verification

• TypeScript: tsc --noEmit — clean
• Backend tests: 2968 passed, 11 skipped
• Ruff: all checks passed
• Pre-commit hooks: all passed

Net: -66 lines (519 insertions, 585 deletions) across 13 files.

In general, the fix is to avoid an empty except block: either narrow the exception type or, if all exceptions must be suppressed to protect callers, at least log and/or capture the error and add a clarifying comment. That way, operational issues with memory.close() are visible without changing runtime behavior for callers using _graphiti_session.

The best minimally invasive fix here is to keep the broad except Exception: (so we still never propagate close-time errors) but handle it by logging the exception and sending it to Sentry with capture_exception, plus an explanatory comment. This uses only existing imports (logger and capture_exception are already defined) and doesn’t modify any external interfaces or control flow, just adds observability in the one finally block.

Concretely, in apps/backend/analysis/failure_storage.py, within _graphiti_session’s finally block (lines 63–66), replace the except Exception: pass block with an except Exception as exc: block that logs the failure and calls capture_exception(exc), and include a brief comment clarifying that shutdown errors are intentionally ignored for callers.
