+# Logging and Observability
+
+Structured, multi-consumer logging from the start.
+
+## Architecture
+
+- Terminal + OpenTelemetry (OTEL) output. Add syslog for daemons.
+- Structured logging (JSON or key-value) — no free-form strings.
+- App writes to stdout only (12-Factor XI). Environment handles routing.
+
+## OpenTelemetry
+
+- OTEL from the start unless user opts out. Traces, metrics, logs as three pillars — traces first for distributed systems, metrics first for monoliths.
+- Use `OTEL_EXPORTER_OTLP_ENDPOINT` env var — never hardcode endpoints.
+- Propagate trace context across service boundaries.
+- Use OTEL semantic convention attribute names (`http.request.method`, `url.path`, `http.response.status_code`).
+
+## Rules
+
+- Incoming requests: log method, path, status, duration, trace ID.
+- Outgoing calls: log target, method, status, duration, trace ID.
+- Errors: log operation, sanitized input, stack trace, trace ID.
+- Never log secrets, tokens, passwords, or PII.
