Open a separate workplan for the budget/usage recording layer surfaced
by the T03 conversation. Three-layer design: layer 1 (per-infospace
budget log) and layer 3 (state-hub emission) live here; layer 2
(cross-application quality observations for adaptive routing) stays in
llm-connect LLM-WP-0004.
Seven tasks cover plan snapshot persistence, run usage rollup,
rate-table cost computation, plan-vs-actual variance, state-hub token
events with hub-down isolation, a workspace-level rollup CLI, and
archive integration so IB-WP-0014 packages carry their budget shape.
