Phase 37 · corridor or rewrite

Bend the channel, not the map

AT-0293 → AT-0302. Deterministic toy benchmark seed 293: an eighty-node chain, a target pair twenty-four links apart, and one question — is deforming only the corridor between them genuinely cheaper than deforming everything, or is that just the price list we happened to write down?

The lesson before the numbers

A localized corridor buys the same compression far more cheaply than a global rewrite — under the assumed cost rule.

SeedSeed 293 reproduces the recorded corridor benchmark.Nodes — 80Places on the chain. Links are one fewer.Target shrink — 0.449Every comparison is bisected onto this exact compression.Amplitude price — 2.00Charge per unit of deformation squared, restoration included at the same rate.Gradient price — 0.50Charge for sharp changes between neighbouring links. This is the corridor's natural weakness.Rate cap — 0.12Largest edit permitted on one link in one step. Geometry cannot change instantly or remotely.Hold — 14 stepsHow long the corridor stays open before restoration begins.Lattice side — 13Square lattice used to test whether the corridor is a one-dimensional artefact.
