Map current model invocation, sanitization, audit, policy packs, RAG, and host DI seams to proposed Microsoft.Extensions.AI concepts for the governed pipeline migration. Co-authored-by: IanFrelinger <IanFrelinger@users.noreply.github.com>
Add Nexo.AI.Pipeline with keyed local:ollama and local:onnx chat clients, wire optional registration through hosting Phase 13b when Nexo:UseMeaiPipeline is enabled (default off), and cover registration with FakeChatClient tests. Legacy IProviderFactory path remains default. Co-authored-by: IanFrelinger <IanFrelinger@users.noreply.github.com>
Introduce UseNexoGovernance with fixed PolicyGate → Sanitizing → Auditing order on every keyed IChatClient, plus unit tests for deny short-circuit, PII redaction, audit outcomes, and composition/architecture guarantees. Co-authored-by: IanFrelinger <IanFrelinger@users.noreply.github.com>
Introduce policy × availability routing outside per-target governance stacks, with audited route decisions and a table-driven matrix of local/cloud fallback scenarios. Co-authored-by: IanFrelinger <IanFrelinger@users.noreply.github.com>
Register cloud:bedrock:{fast,balanced,heavy} with configurable model ids,
reuse the default AWS credential chain, keep Bedrock SDK clients out of DI,
and cover routing/sanitization/audit with fake-transport tests.
