No native implementation is inferred from the registry: only puts is covered.

This real call is unresolved, not free, not data, and not doomed.

The caller's obligation is checked independently of any invocation's existence.

Every completed puts invocation either returns its W result or exhausts resources; it cannot terminate the process or yield a capability panic.

Returned integers bind the source's v1 without consuming main's return.

Whatever puts returns, main's next real core instruction returns zero, and the retained snapshot is exactly the invocation's final memory.

An actual returning contract call followed by main's return reaches the existing machine terminal. No exit observation is appended here.

Before the call, the literal retains its actual global region and bytes.

This invariant establishes the entire NUL-inclusive argument check.

The initialized source module establishes the literal invariant.

A safepoint cannot free GlobalData as though it were a heap object; non-moving bytes preserve the first NUL and the literal's contents.

The source's copy point, after its entry block has consumed fuel.

After the call, return zero reads no old literal or argument state.

Entry consumes fuel or reports OutOfFuel; neither is a library transition.

The literal copy has no memory effect or dynamic allocation.

The no-locals return ignores puts' result, even EOF.

There is exactly one external-call syntax at the reached call point.

The four application phases and permitted terminals; none deletes a failed precondition or silently turns it into a native safety result.

This environment/library premise requires the opaque representation and writable roots to survive collector safepoints, including permitted rewriting of capabilities to already-freed objects. It is not an extra Runtime axiom. The literal preservation is proved above.

Only the facts main still needs are retained before its call; argv is unused.

Safepoints retain those facts under the explicit stdio-stability premise.

Safe finite application outcomes include resource refusal and fuel exhaustion, not unreachable/stuck/unchecked/capability-panic or contract-violation endings.

The actual configuration shape and the caller obligations at every phase.

Every external call in a body state is this puts, with its obligations proved.

Ordinary core steps retain the exact source phase and its needed facts.
