fable

Use when the user asks "what changed", "what breaks if I touch X", "what is the blast radius / change impact", "what should I re-verify before claiming done", "show the timeline / churn for this entity", or when working in a project that uses warpline for temporal change-impact tracking. warpline is the Weft federation's temporal authority; its MCP tools (mcp__warpline__*) answer change-impact and reverify questions, enrich-only, from a local-first dated store.
