User history detail only shows the first output of a multi-image run

Start in components/console/CallDetailDrawer.tsx, focusing on the user variant of MediaStage and its selectedAsset logic; compare it with the existing admin-only asset switching. Review lib/console/activity-assets.ts for the one-URL usage-ticket behavior. Done means the user drawer can inspect every persisted output while keeping one history row and the run-level cost.

Summary

A single run_capability job that returns multiple outputs (e.g. Flux Schnell with num_images: 4) correctly persists every image as mcp_assets and shows as one history row. User history detail then stages only the first output. There is no way to page or open the rest.

This is a user-drawer gap, not a persistence or billing bug.

Expected

• One history row per execution (one runs row / gateway_request_id).
• User detail can inspect every stored output (gallery, pager, or output list).
• Cost stays the joined PymtHouse receipt/manifest for that run (not num_images × unit price).

Actual

• History list: one row. Correct.
• Sidebar still shows num_images: 4. Correct.
• extractRunOutputs walks images[] and persist writes all public media URLs. Correct — MCP returned four asset IDs for the Schnell batch.
• CallDetailDrawer MediaStage is a single slot. It picks selectedAsset, else the first image/video/audio output, else assets[0]:

// components/console/CallDetailDrawer.tsx
const outputAssets = activeDetail?.assets.filter((item) => item.role !== "input");
const asset =
  outputAssets?.find(/* selected */) ??
  outputAssets?.find((item) => /^(?:image|video|audio)(?:\/|$)/i.test(item.mediaType ?? "")) ??
  outputAssets?.[0];

• Click-to-switch asset list is admin-only.
• User variant never renders result images[] — only submitted params plus inference.
• Usage-ticket attachment also keeps one URL per gateway job (lib/console/activity-assets.ts).

Not a defect

Repro

1. Run Flux Schnell once with num_images: 4 (MCP livepeer-example/fal-flux-schnell).
2. Open /home history and the resulting row.
3. Confirm the sidebar says Num Images 4 and the stage shows only one image.
4. Compare admin run detail: asset list can switch outputs.

Example run from local MCP: 4a18002c-c778-4416-a2b1-41ccb5885c60 (job_7fa2242c6d634f8f).

Suggested fix

Expose the already-persisted outputs on the user drawer (thumb strip / prev-next on MediaStage, or the same asset list admin already has). Keep one history row. Do not invent per-image cost unless billing evidence says so.
