07 — Ingestion, Four Flows, Normalization and Governed Writes

Canonical reference: 00-SPINEWORKSPACE-INTEGRATEWISE-CANON.md §16
Status: Canonical

---

1. Gateway

Gateway is the tenant-aware ingress boundary for validation, tracing, rate limits and routing.

2. Loader Runtime

Loader Runtime is the sole outer ingestion and canonical-write entry. It routes data through four flows.

Flow A — Structured Operational

Entities, transactions, metrics, lifecycle changes, provider events and structured relationships.

Flow B — Unstructured Context

Documents, messages, email, meetings, transcripts, files, chunks, embeddings/search representations and evidence.

Flow C — AI and Cognitive Continuity

Twin sessions, AI proposals, candidate memory/knowledge, synthesis and promotion candidates.

Flow D — Platform Binding and Control

Identity, configuration, connectors, capabilities, policy, execution, sync and observability state.

3. Normalizer and Triage

Normalizer handles deterministic parsing, validation, mapping, resolution, deduplication and entity preparation. Triage handles ambiguous, AI-originated, conversational and knowledge candidates, preparing them for governed promotion.

Triage classifies. Governance authorizes. Governed Writers commit.

4. Governed Spine Writers

Canonical writes enforce tenant scope, schema, policy, provenance, evidence, idempotency and atomicity. Neither an agent nor an execution runtime writes canonical truth directly.
