    "description": "## Parent\n\n#46\n\n## What to build\n\nGuarantee that complete tracing and counterfactual analysis remain observational and responsive under representative and loaded annual plans. The planning outcome appears when planning work completes, tracing cannot consume the planner deadline or alter its decisions, stale or failed explanation work is isolated, and the exact latest trace remains local and untruncated.\n\n## Acceptance criteria\n\n- [ ] Planning-work time is accounted separately from trace creation, materialization, transfer, and rendering.\n- [ ] A deliberately slow trace consumer cannot change candidate order, completed phases, interruption point, incumbent, or final outcome.\n- [ ] The planning outcome becomes usable before a delayed full trace finishes loading.\n- [ ] Trace transfer or rendering failure leaves the planning outcome and calendar intact with a local explanation error.\n- [ ] Counterfactual failure leaves the selected plan intact and can be retried or abandoned safely.\n- [ ] Starting a new calculation terminates or ignores every trace and counterfactual task from the previous calculation.\n- [ ] Only the latest trace is retained in memory; no trace is persisted, exported, or sent off-device.\n- [ ] Representative and loaded benchmark scenarios preserve their pre-tracing planning outcomes and planning-work budget.\n- [ ] A loaded scenario proves that every actual evaluation is retained even when trace delivery exceeds ten seconds.\n- [ ] The UI thread remains responsive while planning, tracing, and counterfactual analysis run.\n- [ ] Existing lint, type-check, unit-test, benchmark, and production-build checks pass without a new solver, backend, or test framework.\n\n## Blocked by\n\n- #51 — Explorer une décision de trace sur le calendrier\n- #52 — Expliquer un calcul incomplet\n- #53 — Expliquer un conflit d’obligations",
