Models a real walking-together participant under load: continuous cursor movement (awareness), periodic keyed-map roster upsert, and periodic URL shares to the chat array. Lets us load-test ~100 active participants — the scenario that took the room down before the keyed-map fix. Also fixes the stale root package.json load-test script paths (load-test/ -> tools/load-test/, where the harness was moved). Validated locally against a wrangler dev worker at 100 users: 0 client errors, 100% propagation, no DO overload/503/memory failure. The only server-side event was the per-connection message-rate limit (1000 msg/sec) closing some very-chatty synthetic clients, which auto-reconnect.

Summary
Adds a
walking-togetherscenario to the load-test harness so we can verify the page holds up with ~100 active participants — the scenario that crashed the room before the keyed-map roster fix.Each virtual user behaves like a real participant: continuous cursor movement (awareness, 10Hz), periodic keyed-map roster upsert, and periodic URL shares to the chat array.
Also fixes the stale root
package.jsonload-testscript paths (load-test/→tools/load-test/, where the harness was moved in an earlier refactor but the scripts weren't updated).Results (local wrangler dev, 100 users, transient mode)
How to run
Doc-bounded-ness is covered by the companion soak test (
smoke:partykit:soak), which measures struct count from a connected client (the load-test admin-inspect can't read live doc size in transient mode).
