New tab consumes auto_explore.run_auto_explore(). UI:
- Header showing current model + workload + per-PE HBM budget
- Run sweep button (spinner while ~28k configs run in ~5-10s)
- 4 metric cards: enumerated, feasible, pareto count, best latency
- 2-panel scatter:
* latency vs PEs (feasible in grey, Pareto coloured by efficiency,
dashed line connects Pareto in PE order to show the trade-off curve)
* HBM utilization vs latency for Pareto, coloured by PE count
- Sortable Pareto table
- "Load into sidebar" widget: pick a row, sets the sidebar
session_state keys (cp, tp, pp, dp, tp_placement, cp_placement,
cp_ring_variant, kv_mode, ffn_scope_label) and st.rerun()s so the
user can flip to another tab and see the full breakdown.
Session-state caches the last sweep result under _auto_explore_result;
if the model/workload/HBM change without re-running, a warning suggests
refreshing.
Ffn_scope_label mapping is dynamic (contains substituted divisors), so
the Load button reconstructs the exact label using the target
cp/tp/dp values before assigning to session_state["ffn_scope_label"].
Verified:
- app.py parses cleanly
- All 9 pytest tests in test_auto_explore.py still pass
- Smoke: matplotlib + pandas + auto_explore imports round-trip
Next: verification pass across Qwen 3 8B and Mixtral 8x7B; polish.
