Width: independent of viewport (390px race flow).

At 2026-11-05T19:49:55Z, with genesis=1793735400 and roundSeconds=600, start round 288, run two seconds, return to the menu, re-enter Race, run another 1.3 seconds and pause.

At 19:50:01Z let round 288 settle with one wheel turn (0.878m), then resume and allow the next settlement pass.

Executed the actual mountRace start, animation loop, destroy, pause and resume handlers plus settlePending in Node with controlled animation frames and an in-memory DOM/canvas/storage adapter.

Measured: the first 2.0241m entry settles for 102 points; resume banks 1.318669m to a new entry for the same round, paying another 101.

Final balance 703 and wins 2; expected a single 3.342769m round worth 103 points, balance 603 and wins 1. view-race.js:198 skips banking while paused, and :208-211 banks the old round on resume.

Browser execution was unavailable; this is an executed view/store lifecycle reproduction.

Width: independent of viewport; affects home and race at 390px and 1440px.

Serve a successful /v1/status measurement at 2026-11-05T19:40:05Z with freshness=online, coreStatus=ACTIVE, receivedAt and observedAt equal to that time, staleAfterSeconds=120, speedMmPerSecond=1000, rpmMilli=60000 and distanceMm=1000.

Five seconds later return HTTP 429 with Retry-After: 600.

Advance the clock 121 more seconds without another response.

Executed the real api.js polling and reading functions in Node with controlled fetch, timers and Date.now.

Measured at age 126s: phase=ok, reading().stale=false, wheelLabel()="Squeektoshi is running", ghostSpeed()=1 m/s, retry still 479s away.

Expected: stale label and no live ghost motion after age 120s.

The public freshness contract is documented at https://docs.squeekchain.com/developers/api/#pipeline-status-get-v1status.

Browser execution was unavailable; the state and returned UI label were measured directly.

Width: independent of viewport (390px Predict flow).

With genesis=1793735400 and roundSeconds=600, render Predict at 2026-11-05T19:49:59.500Z with recent known zero-work rounds.

The heading is “Call round 289”.

Select Rest and the 100-point stake; submit at 19:50:00.250Z before the one-second view refresh.

Executed mountPredict/update, the real radio change handler and form submit handler in Node using an in-memory DOM/storage adapter and a controlled clock.

Measured: heading remains “Call round 289”, but the stored pending entry has round=290, stake=100 and balance falls from 500 to 400; status says “Bet placed on round 290.” Expected: reject the expired round-289 selection without charging points.

Browser execution was unavailable; handler behavior and rendered text were measured directly.

Width: independent of viewport (390px and 1440px Predict).

Return /v1/measurement/stats?range=7d with rounds.medianActiveWork=null and rounds.activeRateBps=0, a valid schema state when no active rounds have been observed; let core supply 24 known zero-work rounds.

Execute mountPredict(root).update().

Measured with the real view and an in-memory DOM adapter: the stat text is “Median active, 7 days 0.0 m”.

Expected: “Not available” or no median row.

Squeekchain’s published schema explicitly allows null at properties.rounds.properties.medianActiveWork via $defs.d4_nullableDecimal: https://docs.squeekchain.com/assets/api/measurement-stats.json.

Browser execution was unavailable; this exact rendered text was obtained by executing the view.

Width: independent of viewport; the same explanation appears on Race at 390px and 1440px.

Read “your metres up to 300, plus 100 if you beat his round.

Otherwise half your metres.” Complete 20m in a round that closes with zero wheel turns.

Executed settleEntry({kind:"race",metres:20},0): actual status=rest, payout=10, result=0.

The displayed formula implies 20+100=120 because 20m beats 0m.

The same contradictory promise is in src/js/view-home.js:83.

Expected: disclose the zero-work exception before Start race and in the shared explanation.

Copy and settlement were checked directly; browser rendering was unavailable.
