Why "why did our infra costs jump in Q2?" doesn't fit a graph

TL;DR : some questions don't have a fixed path through your data (search docs, hit a table, compute, verify, answer — in whatever order/combination the question needs), and drawing a graph for that class of question means either enumerating every path up front or hiding an if/else forest inside one node. ctxloom replaces the graph with typed artifacts and agents that react to their appearance — below is the same use case built both ways, side by side. The problem Picture a typical question from a finance lead in an internal chat assistant: "Why did our infra costs jump in Q2?" Answering this honestly requires: Finding relevant documents — the pricing guide, the discount policy (Confluence/docs). Pulling structured data — a CSV/table of monthly spend (GitLab/S3/DB). Computing an aggregate — not "roughly", an exact number from the table. Cross-checking textual claims against the numbers — not letting the model invent a cause the data doesn't support. Returning the answer together with proof: where each part came from. The next question — "what if we hadn't moved to the Pro plan?" — needs a different path: a different source, a different calculation, a different verification chain. There is no universal graph for this class of questions — you can draw a graph for one specific question, but not for the class. This is exactly what typical graph frameworks (LangGraph, CrewAI, etc.) make you pay for in complexity: either you draw a graph for every possible path up front, or you end up with a hidden branching if/else inside one node that nobody can later explain. How this looks in ctxloom ctxloom has no execution graph — it has artifacts (typed, versioned objects) and agents that react to their appearance . The breakdown above is just a chain of artifacts: Question │ ▼ SourceRef (ranked references to sources) │ ▼ TypedDoc / Spreadsheet (lazily resolved content) │ ├──► Evidence (facts extracted from text) │ │ │ ▼ │ Claim (a statement + verification against Evidence) │ └──► C
