Research & Analysis Workflows

Author and refresh the arc42 sections arc42 owns as prose (per ADR-0004 — arc42 owns ALL narrative; arch-c4 only emits diagram + DSL-derived table blocks in §3/§5/§7). Five modes: §2 Constraints (mints CST-NN), §4 Solution Strategy (links ADRs, no new IDs), §6 Runtime View (mints SCN-NN; embeds a C4 dynamic view OR an arch-uml sequence via a declared-figure dependency), §8 Cross-Cutting Concepts (mints CC-NN; may pull an arch-uml class/state/ER figure), §11 Risks and Technical Debt (mints RSK-NN). Reads upstream artefacts (ADRs, quality attributes, bounded contexts, FBS, personas, use cases) to fill content — never invents decisions. Output: docs/architecture/arc42/{02,04,06,08,11}-.md. Triggers on: arc42 constraints, architecture constraints, solution strategy, runtime view, runtime scenario, cross-cutting concepts, logging strategy, error handling strategy, security concepts, risks, risk register, technical debt register, arc42 §2, arc42 §4, arc42 §6, arc42 §8, arc42 §11.

Create, refresh, and freeze Architecture Research notes that inform ADR decisions — regulatory landscape, certification options, infrastructure norms, vendor evaluations, security/compliance baselines. Question-driven format with verified sources + confidence ratings + explicit ADR linkage. Use when asked to research a regulatory question, document a compliance baseline, capture a vendor evaluation, or build the evidence base before an ADR. Triggers on: architecture research, regulatory research, compliance research, certification research, infrastructure research, vendor evaluation, research note for ADR, decision-support research, evidence base, research doc.

Create or plan quantitative business model documents under docs/business/06a-models/. Supports four modes: catalogue the model set and build order for the venture shape, scaffold a single canonical model file, fill the funnel with project context, or refresh assumptions when new evidence arrives. Use when the user asks to create a TAM/SAM/SOM model, savings or recovery model, customer ROI model, market-sizing doc, or any quantified funnel for investor or sales narratives. Triggers on: create a business model, plan the models, which models do we need, scaffold a TAM, bootstrap a quant model, fill a model template, write a market-sizing doc, or model a product, feature, or flow. Uses the qm-NN-{topic} naming convention.
