Add --worker <id> and --level <level> filtering flags to both "fabric tui"
and "fabric web" commands. Filters are applied at the tailer level for
efficiency, before events are added to the store.
- Add --worker <id> option to filter by specific worker ID
- Add --level <level> option to filter by log level (debug, info, warn, error)
- Validate level filter against valid levels
- Pass filter to TUI app for header indicator display
- Pass cliFilter to web server for UI indicator display
- Apply filters in tailer, OTLP/gRPC, and OTLP/HTTP event handlers
Also adds heap snapshot options to web command for leak detection:
- Add --heap-snapshots flag to enable automatic heap snapshots
- Add --snapshot-interval <minutes> option for snapshot frequency

- /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.

NEEDLE log retention for ~/.needle/logs/. The directory had grown to
103k files / 11GB with no cleanup. Adds:
- fabric prune command: archives old files into dated tar.gz, deletes
expired archives, with configurable age thresholds
- mend.logs_pruned events emitted to fabric-mend.jsonl for FABRIC tailer
- systemd timer (fabric-prune.timer) for daily automatic pruning
- 9 tests covering archive, delete, dry-run, edge cases
Ran initial prune: 103,857 -> 1,006 files, 8.6 GB freed.

- resolveSource() now returns { kind: 'directory'|'file', path } instead
of appending workers.log to directories
- New resolveFromOptions() handles CLI flag precedence: --source > --file > default
- Default (no flags) now tails ~/.needle/logs/ as a directory via DirectoryTailer
- --source <nonexistent-path> prints clear error and exits
- -f/--file keeps single-file LogTailer behavior for backwards compat
- tui, web, and tail/logs commands all updated
- replay and digest commands unchanged (file-only, no --source)

Wire shared EventDeduplicator across all ingestion paths (JSONL tailer,
OTLP/gRPC receiver, OTLP/HTTP receiver) so duplicate events from dual
ingestion are silently dropped on (session_id, worker_id, sequence).
Also adds docs/needle-exporter-wiring.md (OTLP configuration guide for
NEEDLE), SpanDag React component, EventFilter.eventType field, and
various test/layout fixes.

Add --source flag to tui/web/tail subcommands for specifying log source
as file or directory (directories get workers.log appended). Add 'logs'
as alias for 'tail' subcommand per plan.md CLI spec. Update README.md
with fabric logs examples and --source usage.

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.

Feed replay events into the store's analytics pipeline via store.add()
in the onEvent callback, enabling worker analytics, error grouping,
cross-reference tracking, collision detection, and semantic narrative
generation during replay sessions. Print analytics summary on replay end.

- Added authToken option to WebServerOptions interface
- Created createAuthMiddleware function for Bearer token auth
- Applied auth middleware to POST /api/events and /api/events/batch
- Updated CLI to read FABRIC_AUTH_TOKEN env var
- Added comprehensive tests for authentication scenarios
- Updated POST /api/events test cases to use auth token
- All tests passing successfully
Changed all blessed imports from namespace import (import * as blessed)
to default import (import blessed from 'blessed') in 28 files.
This fixes "blessed.screen is not a function" runtime error that occurs
when ESM modules import CommonJS blessed package with namespace syntax.
Also includes WorkerAnalyticsPanel property additions for type compliance.
Fixes: bd-31x

Implement smart error grouping to cluster similar errors together and reduce
noise in the activity stream. Uses pattern matching on error messages and
stack traces to group related errors.
Features:
- Error categorization into 9 categories (network, permission, validation, etc.)
- Pattern-based fingerprinting for grouping similar errors
- Normalization of variable data (IPs, paths, UUIDs, timestamps)
- Severity calculation based on frequency and recency
- Integration with InMemoryEventStore for automatic error tracking
New files:
- src/errorGrouping.ts - Error grouping module
- src/errorGrouping.test.ts - Comprehensive test suite (34 tests)

Implements bd-3a4 and bd-2pa.1 (project setup):
- Initialize npm project with TypeScript configuration
- Add package.json with build scripts and dependencies
- Create src/ structure with types and CLI entry point
- Add CLI commands: tui, web, tail (placeholders)
- Configure tsconfig.json for NodeNext modules
This addresses worker starvation (bd-29a) by demonstrating
that direct implementation is a viable alternative when
workers cannot claim beads due to dependency resolution issues.
