Shared OpenTelemetry engine for the @vymalo OpenCode plugin suite. Holds the exporter wiring, resource building, the telemetry recorder, and the token-source seam in one place so @vymalo/opencode-otel (and any future OTEL-aware plugin) can share it instead of forking it.

Extracted from @vymalo/opencode-otel.

What it provides

config.ts — resolveOtelConfig and the env/command parsing it depends on.
providers.ts — createProviders / buildResource, the OTLP exporter and SDK provider wiring for traces, metrics and logs.
recorder.ts — TelemetryRecorder, the OpenCode-hook-to-OTEL-signal mapper.
instruments.ts — the counters/histograms the recorder writes through.
token-source.ts — bearer-token injection for authenticated OTLP exporters.
export-logging.ts — failure-logging wrapper around exporters.
propagation.ts — W3C trace-context propagation into provider fetch.
vcs.ts — git remote/branch detection for resource attributes.
deferred.ts — bounded-wait resource attributes for late-arriving events.
logging.ts — structured logger with level filtering.
types.ts — the shared config/option types.

Usage

import { resolveOtelConfig, createProviders, TelemetryRecorder } from "@vymalo/opencode-core-otel";
