Wheel Run: endless survival race for Squeekchain Genesis. Poll https://api.squeekchain.com/v1/status every ~1.5s. ACTIVE RPM/speed raises scroll rate, hazard density and score multiplier; IDLE slows the burrow; each settledThroughRound increase triggers a soft settlement quake with debris.

Desktop: Space/↑ jump, ↓ slide, Esc pause; mobile tap to jump. Dark playful UI with live badge (ACTIVE/IDLE), Score/Best/Mult HUD. Single-page game site, public HTTPS on IPFS.

No wallet connect inside the game. Do not claim SQK airdrop.

Saved three reproducible findings in .imd-findings.json: stalled polling, lost settlements while paused, and ineffective hanging-root hazards.

mediumA pending status request stops polling and leaves stale ACTIVE telemetry displayedsrc/api.js:39
The hosted dist/assets/index-RP-90QzK.js contains the same logic in ee(): fetch has no timeout or cancellation, and the next poll is scheduled only in finally after the response and JSON body finish. Freshness is also evaluated only after a response. If one request stalls, the game stops polling and keeps the previous ACTIVE speed, multiplier and live badge even after the measurement exceeds staleAfterSeconds.

A bounded request timeout and independent freshness expiry are needed to keep the live game accurate.
Open dist/index.html through an HTTPS static host.

Intercept https://api.squeekchain.com/v1/status and first return HTTP 200 JSON {"measurement":{"freshness":"online","observedAt":"","staleAfterSeconds":120,"coreStatus":"ACTIVE","rpmMilli":40000,"speedMmPerSecond":250},"builder":{"anchor":{"settledThroughRound":"10","blockHeight":"100"}}}, replacing the timestamp with the current time.

Leave the next request pending without resolving or rejecting it for more than 120 seconds (a controllable fetch stub returning new Promise(()=>{}) reproduces this).

Expected: the request times out, polling resumes, and expired telemetry becomes offline with the soft gameplay fallback.

Actual: there is no next scheduled poll; the badge stays ACTIVE · 40.0 rpm and the multiplier remains ×3.40.

This was reproduced by executing the exported bundle with controlled fetch and timer callbacks.
mediumSettlement updates received while paused are permanently discardedsrc/main.js:745
The feed consumes and advances its settlement high-water mark even when the game is paused, while this callback only triggers a quake in playing mode. Resuming does not compare the current settled round with the last round shown in-game. Consequently, the required quake and debris never occur for a settlement increase received while paused.

This is present in the hosted dist/assets/index-RP-90QzK.js, in the we feed callback; queue the event for resume rather than losing it.
Return fresh IDLE or ACTIVE status responses with builder.anchor.settledThroughRound="10" and start a run.

Press Esc.

On the next poll return the same payload with settledThroughRound="11", then keep returning 11.

Press Esc again to resume.

Expected: the missed settlement produces a soft quake with debris on resume.

Actual: the HUD advances to 11 but no quake or debris appears on resume or subsequent polls.

Executing the exported bundle confirmed settlementIncreased=true while paused, followed by settlementIncreased=false and quake=0/debris.length=0 after resume.
lowHanging roots cannot collide with the player, making their slide mechanic ineffectivesrc/main.js:217
The hanging-root branch in the hosted dist/assets/index-RP-90QzK.js (R) places roots at y=70 with heights from 110 to less than 180. Their collision boxes therefore end below y=248. The standing player hitbox starts at y=388, and even the theoretical jump apex only brings it to about y=270.

These roots can never hit the player, whether standing, jumping or sliding; a quarter of obstacle rolls are harmless despite the slide advice in the collision handler. Position these hazards within the standing player range while leaving clearance for a slide.
In a debugger on the hosted bundle, force Math.random to return 0.999 and start a run with fresh IDLE telemetry.

Every obstacle is then a maximum-height root (h=179.93).

Let multiple roots cross the player without pressing any control; all pass harmlessly and award points.

Jumping also cannot make contact.

Expected: an approaching hanging-root hazard requires a slide or another valid dodge.

Actual: its collision bottom is y=247.93, above the player even at the highest point of a jump.

A controlled execution of the shipped R()/fe() functions with a root horizontally overlapping the player confirmed dead=false both while standing and throughout the jump.
