ZPE-Smell

What This Is

Surrogate receptor-response smell codec. Fixed 35-episode benchmark reaches Spearman 0.9996 with zero mixture, fiber, and adaptation collisions.

ZPE-Smell is one of seventeen public encoding lanes in the Zer0pa ZPE portfolio. It is useful now for audit and replication on the declared benchmark surface. It is improving continuously.

Honest Blocker

We do not claim a digital smell product.; We do not claim anything beyond the surrogate receptor-response scope shipped here.; We do not claim this result is admitted to the broader certified subset.

What We Prove

• On the fixed surrogate receptor-response benchmark surface, the codec preserves retrieval structure with Spearman 0.9996.
• On that same surface, nearest-neighbor recall at 1 is 94.29%.
• On the declared nuisance family cases, mixture collision, fiber collision, adaptation alias, and attack success all stay at 0.00%.
• Image-prefixed nuisance streams do not break smell routing on the committed benchmark surface.
• The full public artifact can be regenerated from the code and matched exactly against the committed proof file.

What We Don't Claim

• We do not claim a digital smell product.
• We do not claim anything beyond the surrogate receptor-response scope shipped here.
• We do not claim this result is admitted to the broader certified subset.
• We do not claim coverage of a full empirical receptor panel or general smell perception.
• This scope is intentional, not a limitation in progress — broader claims will be named explicitly when they are earned.

Upcoming Workstreams

This section captures the active lane priorities — what the next agent or contributor picks up, and what investors should expect. Cadence is continuous, not milestoned.

• Olfactory codec — commercial path definition — Zero-Base Scientific Thinking — GPD Research and Planning Pending. The 35-episode surrogate proves retrieval-structure preservation but lacks commercial weight without empirical receptor data. Active research into commercial path (digital olfaction interfaces, fragrance-formulation AI, anosmia rehabilitation) — each path has different empirical-data requirements; selection precedes any corpus scale-up.
