Status: Feature Already Implemented

The worker memory bar feature described in bead bf-4sdu was already fully implemented in commit ea6e270 (2026-06-07 10:19:27 -0400).

Implementation Summary

Files Created/Modified:

    • Proportional RSS memory bar (4 GB ceiling default, or per-worker limit if set)
    • Peak RSS watermark marker (vertical white line)
    • Text label showing current/limit (e.g., "1.2 GB / 4.0 GB")
    • Swap indicator (🔁) if swap usage > 0
    • Hides bar when rssKb is null

  2. src/web/frontend/src/types.ts (7 lines added)

    • Added memory fields to WorkerInfo: rssKb, peakRssKb, rssLimitBytes, rssPercent, swapKb, pid

  3. src/web/frontend/src/components/WorkerGrid.tsx (8 lines added)

    • Integrated WorkerMemoryBar component into each worker card

Verification

The implementation matches all requirements:

  • ✅ RSS memory bar proportional to 4 GB ceiling (or per-worker limit)
  • ✅ Peak RSS watermark marker
  • ✅ Text label format: "X GB / Y GB"
  • ✅ Hides when rssKb is null
