feat(bd-eir): complete FABRIC↔NEEDLE dovetail — wire cross-source dedup, add exporter docs

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.

# NEEDLE Exporter Wiring Guide
How to configure NEEDLE workers to export telemetry to FABRIC over OTLP.
## Overview
FABRIC accepts telemetry from NEEDLE via three channels:
| Channel | Protocol | Default Port | Data Types |
|---------|----------|-------------|------------|
| JSONL file tailing | filesystem | `~/.needle/logs/` | all events |
| OTLP/HTTP | HTTP+JSON/protobuf | `:4318` | logs, traces, metrics |
| OTLP/gRPC | gRPC (protobuf) | `:4317` | logs, traces, metrics |
JSONL file tailing is the default and requires no configuration. OTLP receivers
are opt-in via CLI flags.
## OTLP/HTTP Metrics (Recommended)
NEEDLE has a built-in `OtlpMetricSink` that aggregates `effort.recorded`,
`bead.completed`, `bead.failed`, and `outcome.classified` events into
cumulative OTLP metric instruments and pushes them via OTLP/HTTP.
### NEEDLE Configuration
In `needle.yaml` (or your config file):
```yaml
telemetry:
otlp_metric_sink:
enabled: true
endpoint: "http://localhost:4318/v1/metrics"
```
### FABRIC Startup
```bash
# Start FABRIC with OTLP/HTTP receiver on the default port (4318)
fabric tui --otlp-http :4318
# Or for the web dashboard
fabric web --otlp-http :4318
# Or for raw tail mode
fabric tail --otlp-http :4318
```
### What Gets Exported
NEEDLE's `OtlpMetricSink` exports these instruments:
| Instrument Name | Type | Description |
|---|---|---|
| `needle.worker.tokens.in` | Sum | Cumulative input tokens |
| `needle.worker.tokens.out` | Sum | Cumulative output tokens |
| `needle.worker.cost.usd` | Sum | Cumulative cost in USD |
| `needle.worker.beads.completed` | Sum | Beads completed count |
| `needle.worker.beads.failed` | Sum | Beads failed count |
| `needle.worker.errors` | Sum | Error count |
| `needle.bead.duration` | Histogram | Bead duration samples (ms) |
Each data point carries `worker_id` and `session_id` attributes so FABRIC can
correlate metrics with the JSONL event stream.
### Alias Resolution
NEEDLE emits `needle.worker.beads.completed` and `needle.worker.beads.failed`
(plural). FABRIC resolves these to the canonical `needle.bead.completed` and
`needle.bead.failed` (singular) via the `INSTRUMENT_ALIASES` map in
`src/workerAnalytics.ts`. No action required.
### Flush Behavior
NEEDLE flushes metrics to the endpoint when either:
- 50 events have accumulated since the last push, OR
- 5 seconds have elapsed since the last push
The flush resets the counters, so each push is a delta since the previous one.
## OTLP/gRPC (Advanced)
For environments where gRPC is preferred over HTTP:
```bash
# Start FABRIC with OTLP/gRPC receiver
fabric tui --otlp-grpc :4317
# Both protocols can run simultaneously
fabric tui --otlp-grpc :4317 --otlp-http :4318
```
NEEDLE does not currently ship an OTLP/gRPC exporter. To use gRPC, configure
an OpenTelemetry Collector as a sidecar:
```yaml
# otel-collector-config.yaml
receivers:
otlp:
protocols:
grpc:
endpoint: 0.0.0.0:4317
exporters:
otlp:
endpoint: "localhost:4317"
tls:
insecure: true
service:
pipelines:
metrics:
receivers: [otlp]
exporters: [otlp]
```
## Dual Ingestion and Deduplication
When both JSONL tailing and OTLP are active, the same logical event may arrive
via both channels. FABRIC deduplicates on `(session_id, worker_id, sequence)`:
1. First arrival wins
2. Subsequent duplicates are silently dropped
3. `EventDeduplicator.droppedCount` tracks how many duplicates were suppressed
Events without a valid `sequence` (legacy formats with `sequence: -1`) are
always passed through, since they cannot be deduplicated.
## Source Priority
When FABRIC writes to the analytics database (`fabric.db`), it prefers
OTLP-sourced values over log-derived estimates:
| Priority | Source | Use Case |
|----------|--------|----------|
| 1 (highest) | `otlp-metric` | Direct instrument values from `OtlpMetricSink` |
| 2 | `otlp-span` | Duration derived from span start/end times |
| 3 (lowest) | `log-derived` | Estimated from JSONL log message parsing |
The `metrics_source` column on `sessions` and `session_worker_summaries`
records which source was used for each row.
## Testing the Pipeline
### Verify OTLP/HTTP connectivity
```bash
# Send a test metric payload
curl -X POST http://localhost:4318/v1/metrics \
-H "Content-Type: application/json" \
-d '{
"resourceMetrics": [{
"resource": {
"attributes": [
{"key": "service.name", "value": {"stringValue": "needle"}}
]
},
"scopeMetrics": [{
"scope": {"name": "needle"},
"metrics": [{
"name": "needle.worker.tokens.in",
"sum": {
"dataPoints": [{
"asDouble": 1500,
"timeUnixNano": "1713693600000000000",
"attributes": [
{"key": "worker_id", "value": {"stringValue": "test-worker"}},
{"key": "session_id", "value": {"stringValue": "abcd1234"}}
]
}]
}
}]
}]
}]
}'
```
A successful response is `{}` (empty JSON object).
### Verify in FABRIC
Start FABRIC with OTLP enabled and check that the test metric appears:
```bash
fabric tail --otlp-http :4318 --json
```
