spec-to-plan
Turn a converged devague spec into a buildable plan by working forwards (the spec→plan leg; drives the `devague plan` CLI group). Seed a plan from a converged frame, add tasks that collectively cover every coverage target (the frame's confirmed claims + honesty conditions), give each task acceptance criteria and an honest dependency order, park genuine unknowns as first-class risks, and export a plan only once it *converges*. Use when the user says "spec to plan", "stp", "turn this spec into a plan", "plan this spec", "make a build plan", or after the /think skill exports a spec. Authored and maintained in agentculture/devague (origin = devague); guildmaster re-broadcasts it to the AgentCulture mesh — it originates in devague, not guildmaster (the supplier post steward→guildmaster cutover).
