Provider-agnostic LLM seam for .NET agents: IChatProvider with OpenAI-compatible and Anthropic-native providers and a routing registry.

Typed agent shells for .NET: Agent<TInput,TResult> and BatchAgent<TItem,TResult> over one primitive - prompt by key, one turn, typed degrade, typed parse.

Document OCR behind a port: IDocumentOcr with an Azure Document Intelligence implementation - structured text, tables as markdown, per-page spatial data.

Pseudonymisation with a separated key (GDPR Art. 4(5)): deterministic cross-run-stable tokens with an AES-GCM encrypted, tenant-scoped key store.

Prompt management for .NET agents: versioned templates, per-client override, cached fallback reads, persistence behind a port, and an HTTP egress source for database-free hosts.

Intake utilities for .NET agents: tolerant XLSX/CSV/OCR-text table reading, date normalisation, and session-local pseudonymisation (PseudonymMap).
