The fix distinguishing between beadsCompleted (all processed) and
beadsSucceeded (successful completions only) was already implemented
in stuckDetection.ts and store.ts.
No code changes needed - verified all tests pass.
Add test coverage for beadsTimedOut counter incrementing on
bead.released events with TimedOut/Deferred outcome.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The fix is already in place from previous commits (47c3396, c047131).
This commit documents the solution for future reference.
The stuck detection now correctly distinguishes between:
- beadsCompleted: all beads processed (including timed-out/deferred)
- beadsSucceeded: successful completions only
- beadsTimedOut: timed-out/deferred beads
Stuck reason text now clearly shows metrics:
'100 processed but 0 successful completions (all timed out/deferred)'

Fix discrepancy where /api/workers returned contradictory data:
- beadsCompleted: 285 (counts bead.released events including timed-out)
- stuck: true, stuckReason: 'Running for 2311m with only 1 completion(s)'
The stuck detection now correctly uses:
- beadsCompleted: all beads processed (including timed-out/deferred)
- beadsSucceeded: only successful completions (bead.completed events)
- beadsTimedOut: new counter for timed-out/deferred beads
Changes:
- Add beadsTimedOut counter to WorkerInfo type
- Increment beadsTimedOut on bead.released with TimedOut/Deferred outcome
- Update stuck detection to show clear reason text:
- 'X processed but 0 successful completions (all timed out/deferred)'
- 'X processed but only Y successful completion(s) (Z timed out/deferred)'
- Add beadsTimedOut to evidence array
Fix acceptance criteria:
- Worker processing 100 timed-out beads shows clearly in UI:
- 100 beads completed
- 0 beads succeeded
- Stuck reason: '100 processed but 0 successful completions'
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Fix the discrepancy between beadsCompleted and stuck detection:
- Rename beadsReleased to beadsCompleted (counts all bead.released events including timed-out/deferred)
- Rename beadsCompleted to beadsSucceeded (counts only bead.completed events - successful completions)
- Fix stuck detection to check succeeded < 2 instead of completed < 2
- Update tests to reflect new metric names
This fixes the confusing case where /api/workers showed:
- beadsCompleted: 285 (all bead.released events)
- stuck: true, stuckReason: 'Running for 2311m with only 1 completion'
Now it correctly shows:
- beadsCompleted: 285 (all processed including timed-out/deferred)
- beadsSucceeded: 0 (successful completions)
- stuck: true, stuckReason: 'Running for 2311m with 285 processed but 0 successful completions'
Fix beadsCompleted vs stuck detection metric discrepancy in /api/workers response.
Problem:
- /api/workers returned contradictory data: beadsCompleted=285 (counts bead.released
events) but stuck=true with "only 1 completion(s)" reason
- stuck detection counted a different metric while beadsCompleted counted bead.released
- When all beads timed out and were deferred, beadsCompleted incremented but stuck
detector saw zero success outcomes and flagged the worker as stuck
Solution:
- Separated beadsCompleted (bead.completed events only) from beadsReleased
(bead.released with release_success, includes timed-out/deferred)
- Updated stuck detection to use beadsCompleted for successful completions
- Added beadsReleased counter to track all processed beads (including timeouts)
- Improved stuck reason to distinguish "processed" vs "successful completions"
- Updated evidence to show both metrics for clarity
Now a worker that processes 100 beads (all timed out) will show:
- beadsReleased: 100
- beadsCompleted: 0
- stuckReason: "Running for Xm with 100 processed but 0 successful completions (all timed out/deferred)"
Acceptance criteria met:
- A worker processing 100 timed-out beads shows clearly that it processed 100 but
completed 0 successfully
- The stuck flag fires with accurate reason text

- Add test case for worker processing 100 beads with 0 successful completions
- Fix incorrect test expecting beadsCompleted to increment on bead.released
- beadsCompleted only increments on bead.completed events
- beadsReleased increments on bead.released with release_success
- Stuck detection now uses unified beadsCompleted metric with clear messaging
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The stuck detection's detectLongRunning function was using text-based
message matching ('completed'/'complete' in msg) to count completions,
while beadsCompleted counts actual bead.completed and bead.released
events with release_success.
This caused confusion: a worker with 285 beadsCompleted (all timed out)
would be flagged as stuck with 'only 1 completion(s)' because the
message filter found few matches.
Changed detectLongRunning to use worker.beadsCompleted directly for
consistency. Updated reason text to clarify 'successful completion(s)'

The OOM event detection and alert banner was implemented in commit ea1406a.
This notes file documents the implementation summary.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Backend changes:
- Add getOomState() to systemCgroupMonitor.ts for lightweight OOM polling
- Track oomKillCount, lastOomAt, oomDetected, memoryCurrentAtOom
- Add GET /api/system/oom-state endpoint in server.ts
Frontend changes:
- Create OomAlertBanner component that polls /api/system/oom-state every 30s
- Show persistent red alert banner when oomDetected=true
- Display oomKillCount and memory.current at time of detection
- Banner dismissable via X button; auto-clears after 1 hour (localStorage)
- Add CSS styling for the banner (red background, icon, text)
- Integrate banner into App.tsx at top of dashboard

The system cgroup memory panel for the web dashboard was already fully implemented:
- Backend: systemCgroupMonitor.ts with memory sampling
- API: /api/system/memory, /api/system/memory/history, /api/alerts/oom
- Frontend: SystemMemoryIndicator (header) + SystemMemoryPanel (detail)
- Integration: App.tsx lines 24, 28, 270, 872-878, 928, 1122-1127
All 2511 tests pass. No additional work required.
- Add SystemMemoryIndicator component showing sparkline and usage in fleet header
- Refactor systemCgroupMonitor.ts for cleaner implementation
- Update index.css with fleet-header layout styles
- Add fleet-header with separator between FleetSummaryBar and SystemMemoryIndicator
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- 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

Add MemorySampler that polls active worker PIDs every 10s to sample
/proc/<pid>/status for VmRSS, VmPeak, and VmSwap memory metrics.
Changes:
- Add MemorySampler class with periodic sampling (10s interval)
- 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

Adds a test case that counts active (non-STOPPED) workers from /api/workers
to satisfy the acceptance criteria of verifying workers_active >= 1.
The /api/summary endpoint does not exist; the frontend computes summaries
from /api/workers directly. This test validates that active worker counting
works correctly after OTLP events are ingested.
NEEDLE emits OTLP attributes with underscore naming:
- needle.worker_id (not needle.worker.id)
- needle.session_id (not needle.session.id)
The normalizer only handled dot-separated forms, causing events
to be dropped when OTLP sink is enabled.
Changes:
- Add needle.worker_id and needle.session_id to OTLP_ATTR_ALIASES
- Underscore forms take priority (checked first in iteration)
- Add test coverage for underscore attribute variants
- Add test verifying underscore forms win over dot forms
Resolves #bead-bf-4hzq
Problem: With only a cgroup-level soft limit, one runaway worker can
consume all available memory before pressure kills it.
Solution: Apply per-process MemoryMax to each needle worker via cgroup v2
direct approach (writing to memory.max). This bounds each Claude Code
session at 4 GB RSS. With 6 workers + fabric-web + VSCode, this stays
well under 32 GB.
Implementation:
- workerMemoryLimiter.ts: Core logic to find worker PIDs and apply limits
- cli.ts: Apply limits at startup for both tui and web commands
- directoryTailer.ts: Apply limits when new log files are detected
Fixes #bf-2q9r
Added systemd-run --scope -p MemoryMax=4G wrapper to all GLM adapter configs
(claude-code-glm-4.7, claude-code-glm-5, claude-code-glm-5-1) to prevent
any single worker from exhausting cgroup memory.
Adds the agentation floating annotation toolbar so annotated UI elements
produce structured markdown (CSS selectors, positions, React component info)
that can be copied/pasted into Claude to provide precise visual feedback.

- Add BUILDING, DISPATCHING, EXECUTING, HANDLING, LOGGING, EXHAUSTED_IDLE states
- These represent the inner loop of bead execution, all map to WORKING display
- DirectoryTailer now re-reads files modified within 4 hours from start on startup
This reconstructs worker state after FABRIC restart without replaying ancient history
- Update VALID_TRANSITIONS to include new state transitions
- Update color/icon mappings for new states
The test 'resumes from saved position when a file is re-activated after
eviction' was incorrectly creating both files before starting the tailer.
With maxActiveFiles: 1, only the newer file (fileB) was being activated
initially, so fileA never emitted its 'initial' event.
Restructured to:
1. Create fileA with content
2. Start tailer (fileA gets activated)
3. Wait for fileA to emit 'initial'
4. Create fileB (triggers eviction of fileA via dirWatcher)
5. Continue with re-activation test
This properly tests the LRU eviction and position checkpointing behavior.
The getEventTime function had a bug where it recursively called itself
when event.timestamp was truthy, causing "Maximum call stack size exceeded".
Fixed by using Date.parse() to convert the ISO timestamp string to unix ms.
All 26 failing TimelineView tests now pass.
Closes: bf-50m5
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
The test adds 10001 events to verify the default maxEvents limit of 10000.
Each event triggers significant processing (collision detection, file
tracking, multiple manager updates), so the default 5s timeout was too
short. Increased to 30s; actual runtime is ~750ms.
Fixes timeout failure in src/store.test.ts > InMemoryEventStore > maxEvents limit
The test 'should use default maxEvents of 10000' was timing out when run
with the full test suite but passed in isolation. Root cause: global
singleton instances (WorkerAnalytics, CrossReferenceManager, etc.)
retained state across tests in the main 'InMemoryEventStore' describe
block.
Added afterEach hook that calls all available reset* functions to
ensure clean state between tests.
Closes: bf-5u6j
Phase 8 (Post-launch Fixes, bd-0nd series) was already complete but the
status line only mentioned Phases 1-7 and 9. Updated to show all phases

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)
