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

Rubber duck Stable Build: Make failure easy to see and recover from instead of maximizing an unverified output figure.

QUICK ANSWER

Make failure easy to see and recover from instead of maximizing an unverified output figure. 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

Prepare the receiving area before starting supply. Leave clearance around the handoff and keep a deliberate stop point so an escaped product does not become a growing pile.

Failure mode to watch

A line can look stable while quietly losing products off-camera. Inspect the first landing and every transition, not only the final destination. A duck leaves the source but remains loose or exits the route before the Maw.

Sources:

Validation checklist

Record whether inputs remain contained, whether a miss can be recovered and whether stopping the source stops accumulation. No success percentage is claimed.

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.
