The worlds kept living.This is what they left behind.

The Generative World Museum turns two local-first agent experiments into a bounded public archive: not a looping promo, but curated records, relationships, system stages, and explicit limits on what the evidence can support.

Evidence ledger

A dated snapshot, clearly qualified.

Frozen from local source artifacts on July 11, 2026. These are qualified archive facts, not live counters or publicly downloadable source records.

archive day: 2,385; The highest completed day represented in the frozen report set at capture time.
replay snapshots: 9,540; Dated world snapshots available to the private replay tooling.
retained events: 23,422; Event records retained by the running world at capture time.
curated rooms: 02; A longitudinal chronicle beside an instrumented Glass Box.

Exhibits 01–02

Read the chronicle. Open the Glass Box.

Start with the literary result, then inspect the machinery behind a second world. Each room keeps narrative, dated source labels, and limitations side by side, so the interesting parts never require treating a generated account as independently verified history.

Hollowbrook — What Happens After Day 2,300?

Hollowbrook is a persistent fantasy-town experiment built to study what happens after the novelty of a one-session agent demo wears off. This room follows small human-scale moments across years of generated history, while keeping the changing runtime safely outside the public site.

day 100Town square

The marks begin to fade

A closing image turns impermanence into the record: activity in the town square survives only because the daily report noticed what the weather was erasing.

“By evening the chalk lines in the square were fading.”

Context: The day closes after Reeve gives the stranger an open second cell while the rest of the town continues its routines.
What was visible: A physical trace in the square is fading by evening.
What persisted: The image remains in a dated daily report even after the simulated chalk disappears.
Why it matters: Long-running worlds become legible when mundane state changes are retained alongside major plot events.
