PulseContext.telemetry constructor
PulseContext.telemetry({})
Syntheses a Telemetry & Observation Blueprint for high‑frequency signals that provide visibility without driving state mutation.
This factory is the architectural standard for Non‑Invasive Monitoring. It ensures that observability pulses carry a consistent Causal Trace while minimising metabolic and storage overhead.
When to use
Use this when emitting heartbeat signals or performance metrics from within a cell.
How it works
- Sets
auditLeveltononeto avoid log bloat. - Sets
priorityto 10 (background). - Sets
sensitivitytopublic. - Uses
deterministicstrategy.
Non‑obvious
- These pulses are never audited – they are pure telemetry.
- They are low priority and will not interfere with critical operations.
Example
final context = PulseContext.telemetry(
baseContext: currentPulse.context,
actor: 'Throughput_Monitor',
reason: 'Reporting batch completion latency',
);
Parameters:
baseContext: Ancestral Context for lineage.actor: The monitoring service or sensor name.reason: The specific metric being reported.purpose: Observation category, defaulting to 'METRIC_COLLECTION'.priority: Urgency, defaulting to 10.
Implementation
factory PulseContext.telemetry({
required Context baseContext,
required String actor,
required String reason,
String purpose = 'METRIC_COLLECTION',
int priority = 10,
}) {
return PulseContext.fromEntries([
// --- Static Pillars (Non-Evolvable Identity) ---
Provenance.actor.entry(actor),
Provenance.traceId.entry(Identity.next()),
if (baseContext is PulseContext)
Provenance.parentTraceId.entry(baseContext.traceId!),
Provenance.sensitivity.entry(Sensitivity.public),
// --- Fluid Boundaries (Evolvable Intent) ---
Provenance.strategy.entry(ReasoningStrategy.deterministic),
Provenance.confidence.entry(1.0),
// Default to none to prevent log-bloat from diagnostic cycles
Provenance.auditLevel.entry(AuditLevel.none),
Provenance.priority.entry(priority),
Provenance.purpose.entry(purpose),
Provenance.reason.entry(reason),
]);
