Summary

Every sandbox-dax-daily run for 2+ weeks merges to an empty summary.results[] — workers complete (e2b builds 7/7 phases in ~83s, records land in task_results) but each worker's submitted summary carries zero provider rows because dax.bench.ts never declared a scoring spec. The platform leaderboard and the provider-weekly-composite bench both read run.summary.results, so dax contributes nothing.

Adds scoring.metrics on totalMs (the build's measured duration): ceiling: 300_000 ms — dax builds run ~20–150s, so typical providers score ~50–93 rather than clamping at 0 — with the same median .60 / p95 .25 / p99 .15 weights tti.bench.ts uses.

Verified with bench check: scoringOk: true. From the next daily run onward the run summary will carry per-provider compositeScore rows; earlier windows stay empty (the composite skips missing data rather than zeroing it).
