- Add SystemMemoryPanel rendering in App.tsx main content area
- Add 'show:memory' command palette action for opening memory panel
- Fix import of SystemMemoryPanel (named export)
- Backend features already in place: /api/system/memory, /api/system/memory/history, OOM tracking, 5-min sparkline
This completes the integration of the system cgroup memory panel that shows:
- Current cgroup memory usage vs MemoryHigh (color-coded progress bar)
- 5-minute sparkline of memory usage sampled every 10s
- oom_kill counter from /sys/fs/cgroup/user.slice/memory.events
- Swap usage when enabled

- Attach rssKb, peakRssKb, swapKb to WorkerState in types.ts
- Integrate with InMemoryEventStore to register PIDs from events
- Expose memory fields on GET /api/workers response
- Broadcast updated memory fields via WebSocket
- Add comprehensive test suite

Implements the missing /api/spans/dag endpoint that was blocking the
SpanDag component. The endpoint queries span events from the store and
builds a hierarchical tree structure for visualization.
Changes:
- Added GET /api/spans/dag endpoint in src/web/server.ts
- Added SpanDagResponse interface to src/types.ts for JSON serialization
- Updated SpanNode interface to use nullable fields (null instead of undefined)
- Fixed src/dagUtils.ts to use nullable SpanNode fields
The endpoint accepts an optional trace_id query parameter to filter
spans by trace, and returns a SpanDagResponse with root spans, total
span count, and trace summary.
Closes: bf-82u8
Backend API endpoints (src/web/server.ts):
- GET /api/workers/compare?worker1=&worker2= — returns WorkerComparison via analyticsManager.compareWorkers()
- GET /api/analytics/workers — returns per-worker WorkerMetrics for leaderboard table
- GET /api/analytics/sessions — exposes historicalStore.getSessions() for cross-session comparisons
Frontend component (src/web/frontend/src/components/WorkerAnalyticsPanel.tsx):
- Comparison view mirroring TUI WorkerAnalyticsPanel behavior
- Leaderboard table with sortable columns
- Historical sessions list
- Worker selection for comparison with diff/percent/winner indicators
Wired into App.tsx with new "Workers" button (⚔️ icon) and command palette action (show:worker-analytics)

Implements Phase 6 Historical session index for comparisons.
Backend (src/web/server.ts):
- GET /api/sessions — list sessions (paginated, with start/end filter)
- GET /api/sessions/:id — get single session detail with per-worker summaries
- GET /api/sessions/:id/workers — get worker summaries for a session
All endpoints use the existing HistoricalStore infrastructure.
Frontend (src/web/frontend/src/components/HistoricalSessionsPanel.tsx):
- Sessions list table with duration, workers, tasks, cost, tokens, time range
- Click-to-expand session detail with worker performance breakdown
- Metrics source badge (otlp-metric, otlp-span, log-derived)
- Empty state with helpful hint when no sessions exist
- Refresh button for manual reload
Integration:
- Added to App.tsx with Sessions toggle button in header
- Command palette action: show:sessions
- Follows existing panel patterns (ProductivityPanel, AnalyticsDashboard)
Closes: bf-5xch

- Add src/serverMetrics.ts (ServerMetrics class for /api/health + /api/metrics)
- Add scripts/fabric-health-check.sh (curl-based liveness probe)
- Wire sd_notify READY=1 on server start and WATCHDOG=1 keepalives in server.ts
so the Type=notify systemd service correctly reports start and keeps the
watchdog alive without an external npm package
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- /api/health returns {status, uptime_sec, version, event_count,
ingest_rate_per_sec, ws_clients, tailer_files_watched, dedup_dropped,
process_resident_memory_bytes}; returns HTTP 503 with status='overloaded'
when maxEventCount is exceeded
- /api/metrics exposes the same counters in Prometheus text format;
fabric_status=0 when overloaded
- Add ServerMetrics.eventCount setter so both endpoints sync from store.size
(fixes fabric_event_count in /api/metrics showing 0 when events added directly)
- Wire --max-events CLI option into `fabric web`; pass maxEventCount and
deduplicator to createWebServer so the memory-bomb guard and dedup_dropped
reporting are actually activated
- Track tailerFilesWatched: set after tailer.start() and update on each event
for DirectoryTailer (uses activeFiles.length getter)
- Add import for Node net module used by systemd watchdog notify
- Add tests: overload guard returns 503, within-limit returns 200, Prometheus
reflects fabric_status=0 when overloaded
systemd service already has Restart=on-failure + WatchdogSec=30 (scripts/fabric-web.service);
liveness guard in server.ts calls process.exit(1) after 3 consecutive overload
checks, triggering systemd restart.

- Warn at startup when FABRIC_AUTH_TOKEN is unset so operators know
POST /api/events is open to any local process; surfaced before
"Press Ctrl+C to stop" so it's visible in systemd journal
- Add "Token rotation" section to README with step-by-step procedure:
generate new secret, update secrets.env (0600), restart service,
verify 401 enforcement; notes that NEEDLE workers reload on next task
start when auth_token uses \${FABRIC_AUTH_TOKEN} substitution
The full auth chain is now in place end-to-end:
~/.config/fabric/secrets.env (0600) → EnvironmentFile →
FABRIC_AUTH_TOKEN env var → server auth middleware → 401/403 on
unauthenticated POST; NEEDLE config auth_token: "\${FABRIC_AUTH_TOKEN}"
routes worker events through the same token.

Move auth middleware before OTLP router mount and apply it as app-level
middleware for all POST requests. This protects event ingestion endpoints
(/api/events, /api/events/batch), OTLP endpoints (/v1/logs, /v1/traces,
/v1/metrics), and cost alert acknowledgement. GET endpoints remain open.
Adds comprehensive auth tests covering 401/403/201 responses.

Mount OTLP/HTTP handlers on the existing Express web server via a second
HTTP listener so OTLP endpoints are reachable at the standard :4318
address without a separate process. Accepts both application/x-protobuf
and application/json content types, routing decoded records through the
same Normalizer pipeline as the gRPC receiver.
