MASA 0.2.0 — observation profile

MASA 0.2.0 adds a versioned Observation profile for normalized source signals without conflating epistemic status, temporal character, or signal kind with availability, freshness, health, confidence, method, or disclosure.

Highlights:

• normative epistemicStatus, temporalCharacter, and signalKind vocabulary
• versioned schema, ontology, JSON-LD context, fixtures, capability catalog, and RFC 0002
• backwards-preserving 0.1 resources alongside the complete 0.2 contract
• refreshed conformance evidence for reader, writer, transformer, agent-host, and publisher classes

The authoritative pnpm check gate passes on Ubuntu and Windows CI, including 60 tests, fixture/schema validation, publint, package inspection, and isolated packed-runtime smoke checks.
