Decision Map

Maps the unresolved architecture, policy, and scope decisions that must be answered before planning can start: one durable decision ticket per question on the issue tracker, typed and blocker-linked under a parent map, with fog-of-war, out-of-scope, a computed frontier, and one decision resolved per invocation. Triggers on: "map the decisions", "what do we need to decide", "identify the unknowns", "not ready to plan yet", "decision map", "chart this effort", "work the next decision ticket", "wayfinder". Use when the destination is still uncertain. NOT for implementation slices of a known feature, use task-decomposer. NOT for milestone plans, use plan-prompts.
