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

Use vi.hoisted() to declare mock classes before the factory runs,
preventing "Cannot access X before initialization" errors that occur
when vitest hoists vi.mock() calls but the factory captures references
to variables not yet initialized.
Fixes errors in:
- src/tui/components/CrossReferencePanel.test.ts (MockCrossReferenceManager)
- src/tui/components/WorkerAnalyticsPanel.test.ts (MockWorkerAnalytics)
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Fix mock hoisting issues in CrossReferencePanel and WorkerAnalyticsPanel test files by:
- Defining mock classes entirely inline within vi.mock() factory functions
- Removing references to external consts that were causing "Cannot access before initialization" errors
- Simplifying getMockFunctions() helper to use the already-imported mocked constructor
The vitest hoisting mechanism moves vi.mock() calls to the top of the file before regular variable declarations, so any consts referenced in the mock factory must also be defined inside the factory or via vi.hoisted(). The simplest fix is to define everything inline.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Fix "Cannot access before initialization" errors in:
- CrossReferencePanel.test.ts
- WorkerAnalyticsPanel.test.ts
Root cause: vi.mock() factory functions referenced variables declared
outside the factory via vi.hoisted(), but vitest hoists vi.mock()
calls to the top of the file before variable initialization.
Solution: Define all mock implementations inline within the
vi.mock() factory functions, removing external variable references.

The vi.mock() callback was capturing mockManagerInstance at module
load time when it was undefined. Fixed by:
1. Changing mock to vi.fn() without return value
2. Adding mockReturnValue(mockManagerInstance) in beforeEach
This ensures the mock returns the properly configured instance when
getSemanticNarrativeManager() is called during panel construction.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Fixed 3 failing tests by correcting the mock setup:
- Moved mock function initialization from module-level to beforeEach
- This ensures fresh mock functions for each test run
- Added stub implementations for all interface methods
- Fixed mock manager instance creation per test
Tests now passing:
- "should refresh narrative from manager"
- "should generate narrative for worker and set it"
- "should generate aggregated narrative and set it"
The issue was that mock functions were defined globally at module
load time, causing them to be stale between test runs. Tests were
setting return values on stale function references, so mock calls
weren't being tracked properly.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Fixed the mock setup for the SemanticNarrativeManager to properly
allow mockReturnValue() to work on the manager methods.
The issue was that the mock class methods were defined as class
properties with vi.fn(() => null), which created new instances for
each test run. By defining the mock functions as module-level
variables and assigning them to the class methods, we ensure that
the same vi.fn() instances are used throughout, allowing tests to
properly configure return values with mockReturnValue().
This fixes 3 failing tests:
- "should refresh narrative from manager"
- "should generate narrative for worker and set it"
- "should generate aggregated narrative and set it"

- Make render() public so tests can call it directly without casting
- Change hide() to call this.render() instead of this.box.screen.render() directly
- This makes hide() consistent with show() and improves test compatibility
These changes address test failures in FileContextPanel.test.ts where:
- Tests call (panel as any).render() directly
- Tests expect mainBoxInstance.screen.render to be called after show/hide

The original mock returned the same instance for all blessed.box() calls,
but the implementation creates 4 separate boxes (main, fileInfo, fileContent,
fileHistory). This caused tests to fail because they couldn't distinguish
which methods were called on which elements.
Changes:
- Make the mock return a new instance for each blessed.box() call
- Track all mock instances in a mockBoxes array
- Keep mainBoxInstance reference for tests that need the primary box
- Fix test expecting setContent on main box to use mockBoxes[1] (fileInfo)
All 57 FileContextPanel tests now pass.
Fixed test setup to correctly capture the mock instances that were
actually used during CommandPalette construction. The previous
approach of re-calling blessedMock.box() after clearing mocks
resulted in checking different mock instances than those used by
the actual palette object.
Changed from:
- Calling blessedMock.box() after construction (different instances)
To:
- Accessing blessedMock.box.mock.results[0]?.value (same instances)
This ensures tests correctly verify the behavior of the actual
CommandPalette instance, not mock instances that were never used
by the palette.

Fix CrossReferencePanel.test.ts and WorkerAnalyticsPanel.test.ts
which failed to load due to vi.mock() hoisting issues.
The vi.mock() factory functions referenced variables declared after
the mock call. When vitest hoists these mocks to the top of the
file, those variables weren't initialized yet, causing
"Cannot access before initialization" errors.
Solution: Use vi.hoisted() to declare mock variables before the
factory runs, ensuring they're available when the mock is evaluated.

1. maxEvents limit enforcement:
- Changed trimming condition from `> maxEvents + TRIM_BATCH_SIZE` to `> maxEvents`
- Now properly trims to exactly maxEvents when limit is exceeded
- Fixed: tests "should trim old events when over limit", "should keep most recent events",
"should use default maxEvents of 10000"
2. Cross-Reference Integration:
- Modified CrossReferenceManager.processEvent() to create immediate worker->event links
- This ensures every event creates at least one cross-reference link
- Fixed: tests "should track cross-references when events are added",
"should create links between events and workers", "should find linked entities"
3. Bead collision detection:
- Fixed detectBeadCollision() to include all workers in collision set
- Added time window check: only detect collision if other worker was active within
BEAD_COLLISION_WINDOW_MS (60 seconds)
- Fixed: tests "should detect collision when multiple workers work on same bead",
"should not detect bead collision outside time window", "should update worker
collision types for bead collision"
All 103 tests now pass (1 skipped).

The hot reload functionality for workers.log was already implemented
in src/cli.ts (lines 152-179). This commit adds comprehensive tests
to verify the behavior.
Key findings:
- workers.log is monitored via LogTailer when it exists at TUI startup
- New events are parsed and added to store/TUI in real-time
- CLI filters are applied correctly
- Deduplication works for canonical NeedleEvents (sequence >= 0)
- Legacy events (sequence < 0) cannot be deduplicated
Known limitations:
- If workers.log doesn't exist at TUI startup, it won't be watched
- File rotation is handled but may have edge cases

Add fs.watch-based monitoring for ~/.needle/logs/workers.log in the TUI
command. When new lines are appended to workers.log, they are parsed and
the TUI updates in real-time without requiring manual refresh.
Key features:
- Separate LogTailer for workers.log alongside the existing DirectoryTailer
- Starts tailing immediately if workers.log exists at startup
- Watches directory for workers.log creation if it doesn't exist initially
- Proper cleanup on shutdown (stops both tailer and directory watcher)
- Applies CLI filters (worker/level) to events from workers.log
