Step 2 · IBM stack
Fourteen IBM tools. Per-tool honesty tier.
Three tools wired at HEAD (Granite Instruct 4.1 8B coaching narration + Granite 4.0 Nano 350M WebGPU edge model + Granite Embedding R2 via HF Inference Providers). Nine at integration with canonical type contracts and backend swap-points per Vinh M3-V1 through M3-V15 (Granite-Docling + Vision + TTM + FlowState + TSPulse + Guardian + LangGraph + 3B routing + Granite Speech; Langflow retained as the export-graph artifact per D-017 G7 + D-054). Two build-time accelerators (Docling library + Mellea v0.5.0 IVR-loop architectural slot). Wave-46 D-058 expansion brought Granite 4.1 3B Instruct fast-path routing + Granite Speech 4.1 2B-Plus speaker-attributed ASR.
Honesty tier rendered as a per-tool status pill on the / page StackBadges grid and the /judges IBM_STACK panel. No tool listed without a runtime role in the pipeline.
