Project P.I.T.T. Rubber duck Compact Build

Rubber duck Compact Build: Reduce footprint only after a reference layout works, keeping access for diagnosis.

QUICK ANSWER

Reduce footprint only after a reference layout works, keeping access for diagnosis. For Rubber duck, start with a visible manual feed, then identify the first direction change that needs a guide surface. Keep the first lane observable rather than hiding it inside a dense machine. This is a planning pattern, not an in-game-tested optimal build.

Startup order

Record the working arrangement before moving components closer. Shorten one segment and compare the same product path; do not change the control method at the same time.

Failure mode to watch

Compression can make collisions and blocked access harder to isolate. Reopen the narrowed section if the first failed handoff moves to that join. A duck leaves the source but remains loose or exits the route before the Maw.

Validation checklist

Check access to controls, product clearance and a way to remove a stuck item. A smaller footprint is not evidence of higher throughput or a lower hardware load.

Trace one duck from source to destination. Separate a source that is not producing from a lane that is producing but missing delivery; only expand the stage that passes the observation.

Not claimed by this plan

No measured throughput, income per minute, guaranteed achievement trigger, exact timing circuit or physics coefficient is supplied. Before this layout is treated as verified, evidence must show the current build, the assembled path and repeatable input-to-output behavior.

Evidence and verification limits

DEFERRED — EVIDENCE INSUFFICIENT. This page documents what is known and what remains unresolved; it is not a verified complete solution.

Editorial planning pattern; no current-build replay of the complete layout. Public reference, noindex until the distinct build is demonstrated.
