📝 WalkthroughWalkthroughGrok usage is normalized across ACP and headless formats, including cache, reasoning, cost, and precision fields. Rollout aggregation and session analytics now preserve these fields. The dashboard renders detailed Grok usage, diagnostics, localized labels, and provider-reported costs. ChangesGrok usage and reported cost
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR can produce incorrect cost and usage totals when Grok events are incomplete, project-specific rows contain provider costs, or reported and fallback-priced rows are mixed. Merge should wait until these bounded accounting issues are fixed and covered by regression tests. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Sum effective row costs before model aggregation.
A model bucket can contain one row with a reported cost and one row without one. The positive partial sum then makes computeRowCost skip fallback pricing for the unreported row.

Preserve reported cost in project Grok rows.
Line 3083 writes total_cost_usd, but the project-specific turn delta in parseGrokBuildIncremental does not copy event.total_cost_usd before addTotals. Project queue rows therefore remain 0 when the same turn_completed event reports a positive provider cost in the non-project queue. Add total_cost_usd: event.total_cost_usd to the project turn delta. Add a project-queue regression test.

Mark missing normalized usage as incomplete.
If normalizeGrokUsage(usage) returns null, this code does not set usageIsIncomplete. If an earlier event was valid, providerCostEvents === usageEvents still passes. The session then labels a partial provider-cost sum as complete and skips model-pricing fallback.
Set usageIsIncomplete when a turn_completed event has missing or malformed usage. Add a fixture with one valid usage event and one missing or malformed usage event.
Proposed fix
const normalizedUsage = normalizeGrokUsage(usage);
-if (normalizedUsage) {
+if (!normalizedUsage) {
+ usageIsIncomplete = true;
+} else {
usageEvents += 1;
addTotals(tokens, normalizedUsage);
// ...
