What Instrumentation does

Structured events

Emit typed evidence events directly from your application code via the Lamdis SDK.

Boundary definitions

Mark where your visibility ends. Know exactly what you can and cannot prove.

Confirmation levels

Every event is scored A through E based on evidence strength — from intent to end-to-end proof.

Correlation engine

Automatically link events across services using workflow instance IDs.

Policy checks

Same policy checks run against SDK events as against runs and assurance evidence.

Coverage dashboard

See which workflows have instrumentation gaps and get actionable suggestions.

How it works

Install the SDK

Add @lamdis/sdk to your service. Initialize with your API key and workflow definitions.

Emit evidence events

Call lamdis.emit() at key points in your code. Include structured data and confirmation metadata.

Define boundaries

Mark where your service's visibility ends — external APIs, third-party services, user devices.

Review coverage

Dashboard shows confirmation levels per workflow. Get suggestions to upgrade evidence strength.

Key features

TypeScript SDK

Fully typed SDK with auto-completion for event schemas and workflow definitions.

Distributed tracing

Workflow instance IDs correlate events across microservices automatically.

Boundary marking

Explicitly declare where visibility ends — no false confidence from missing data.

Level upgrades

Get suggestions to upgrade from Level A to Level D by adding confirmations.

Schema validation

Event schemas are validated on ingest — catch instrumentation errors early.

Event replay

Re-evaluate historical events against updated policies without re-emitting.
