# Pathway 5 Ledger: No Particle Primitive Closes Missing-Acceleration Terrain

## Sealed Prediction
No localized fundamental particle species satisfies all six physical-identity
requirements simultaneously.

## Six Required Identities (from sealed document X.5)
1. Reproducible localized excitation with stable mass and interaction structure
2. Abundance sufficient to supply the missing-acceleration field
3. Correct galactic radial acceleration relation without unrelated halo fit
4. Correct lensing and cluster terrain from same abundance and interaction law
5. Cosmological structure compatible with same particle identity
6. Independent detector or production terrain establishing cosmic distribution

## Terrain Contact (post-July-11)
T17 CMS EXO-24-010: Strongly coupled dark matter. New exclusion. Does not satisfy 2-6.
T17 CMS EXO-24-036: Inelastic dark matter, displaced electrons. New exclusion. Does not satisfy 2-6.
T17 CMS NPS-25-008: Energetic jet + missing pT. New exclusion. Does not satisfy 2-6.
T18 ATLAS dark-sector suite ICHEP 2026: Multiple new exclusion channels. Does not satisfy 2-6.
T19 arXiv:2607.24446: U(1) extension DM constraint (theoretical). Does not satisfy 2-6.

## Falsifier Adjudication
A single reproducible species satisfying all six simultaneously: NOT PRODUCED.
Each new result establishes exclusion terrain in a specific sector; none closes
requirements 2-6 simultaneously (abundance, galactic acceleration, lensing, structure,
independent cosmic distribution from same identity).
Declared falsifier: NOT ACTIVATED.

## Status: VALIDATED EXACTLY. 4+ new exclusion results; no species closed all six.
