Transport sharpness benchmark and source-domain audit

Family 374, source revision fd4aeeb2ee4fc729c18d98444fed42fd0529eeeb. Revised source-informed assessment, 9 October 2026 Australia/Brisbane.

Current decision

Prototype the exact sensitivity benchmark and a solver/model correspondence report. Pricing, usefulness and repeatable profitable delivery are unvalidated.

Reviewed finding and application boundary

Twelve declared definitions were compared with uniform continuum source, quadratic couplings, unique optimal plans and continuous L2 map distance. No intended-model mismatch was detected at this source level. Domain hypotheses exclude degenerate normalization/infinite-distance corners; map uniqueness is almost everywhere. No trusted proof or imported dependency check was run.

The paper provides an explicit constant through radius, coordinate projection volumes and source volume. On K=Y=[-1,1]^2, C_*^2<=9464 gives the conservative rational C=98, if the source theorem is accepted. The exact polygon reference reproduces the thin three-atom construction, target distances and source-map reassignment. 131 finite checks passed. The product opportunity is sensitivity calibration; a discrete, entropic or learned map still needs its own bridge.

Evidence extent

Selected definitions/statements and the recorded manuscript sections were inspected. This is not a full manuscript, import-closure, proof or program verification. Source metadata, semantic observations, computational review.

Next action

Prepare a concrete operational-claim/benchmark control, record every model bridge and numerical error, and retain the unrestricted source construction as separately queued work. No customer outreach, paid computation or deployment has occurred.
