DRAFT - not sent; for author completion and approval after scientific review.

Dear Editors of Artificial Life,

Please consider "The Viable Corridor: A Constraint-Architecture Framework for
Survivable Multi-Agent Optimization" as an Article.

The manuscript examines survivability in synthetic multi-agent systems, fitting
the journal's interest in software models that clarify life-like phenomena. Its
question is how constraint architecture, rather than individual capability alone,
affects long-time viability. A coupled ODE and a stochastic agent ecology explore
resource concentration, coherence and substrate limits. The contribution is a
model-internal demonstration of capability loading multiple constraints and the
limits of single-axis responses. The two models share an author and toolchain;
transfer to real systems remains an uncalibrated hypothesis.

This version incorporates the 7 September 2026 erratum. The originally proposed
sufficiency conjunction is refuted in its Lorentzian continuum reading; a
population-specific, floor-dependent replacement remains open. Historical
measurements are retained. The Article and accompanying Supplement include the
model definitions, limitations and reproducibility information; separate figures
are supplied in vector PDF and 600-dpi PNG.

Codex assisted with editorial shortening, reference-metadata checks, typesetting
and production verification for this review package. The author remains
responsible for the scientific content and must complete the disclosure of any
assistance used during earlier manuscript development.

[Before sending: obtain and address the three independent scientific reviews;
approve the shortened manuscript and Supplement; confirm originality and that
this work is not under review elsewhere; complete funding/conflict, contribution
and tool-use declarations. This draft makes none of those attestations.]
