Frozen v9 protein bridge (1UAO / 1L2Y)

12 Apr 2026 folding-side operator: frozen UQCF-GEM bridge improved backbone ordering on 1UAO/1L2Y. Restricted in-silico. 19 Sep closeout: not a transferable new mechanism. Not full folding.

This is the protein transfer of the UQCF-GEM bridge layer that later shows up in the Villin HP35 R_t post. On 12 Apr 2026 Aaron posted a three-file memo plus a raw trajectory packet and asked whether a Theory of Everything, if real, should generate a testable organizing principle in a domain it was never built for. The posted answer is bounded: a frozen v9 patch produced a reproducible pre-classical ordering effect on two real small-protein targets. Not full folding. Not robust long-range contact closure. Not a TOE proof.

The current UQCF-GEM bridge implementation carries a real multiscale ordering signal that generalizes across small protein targets, especially in backbone organization. The strongest remaining limitation is not local coherence, but productive long-range contact selection and full basin discrimination.

Scoreboard (author’s own 7.6 / 10)

Target Metric Baseline Frozen v9 Note
1UAO (chignolin) best RMSD mean (Å) 4.5584 4.2051 Improved vs baseline and vs v8 (4.4738). Not a decisive p in the memo.
1UAO angle RMS mean 0.8289 0.5809 Strongest 1UAO move.
1UAO dihedral RMS mean 2.0045 1.7647 Improved vs baseline; v8 was 1.6894.
1UAO contact recovery mean 0.3333 0.3077 Mixed. v8 was worse (0.2308).
1L2Y (trp-cage) best RMSD mean (Å) 6.0021 5.4193 Directional. p = 0.0655 in the memo — not decisive.
1L2Y angle RMS mean 0.7891 0.6948 p = 0.0193. The significant 1L2Y cell.
1L2Y dihedral RMS mean 1.8387 1.8346 Unchanged.
1L2Y contact recovery mean 0.3848 0.4061 Slight improvement.

Numbers from Tmp/TOE/uqcf_bridge_v9_update_bundle CSVs and uqcf_bridge_update_v9.md. v9 is scored 7.6/10 in that memo because it transferred better than v8, not because folding is solved.

1UAO RMSD traces, baseline versus frozen v9

Restricted

1UAO RMSD over step: baseline versus frozen v9. Trajectory-level check that the summary gain is not only an endpoint reporting artifact.

uqcf_bridge_v9_trajectory_packet_bundle

1L2Y RMSD traces, baseline versus frozen v9

Restricted

1L2Y RMSD over step: baseline versus frozen v9. Same frozen patch, second target.

uqcf_bridge_v9_trajectory_packet_bundle

1L2Y sigma_bridge trace under frozen v9

Restricted

1L2Y sigma_bridge over step. The trajectory packet’s question: does the bridge observable move with structural ordering, or only appear in the summary CSV?

What the 12 Apr posts claim, and refuse

  • Claimed: backbone ordering improved; angle regularity improved; RMSD moved in the right direction across 1UAO and 1L2Y; v9 is the first patch that looks cross-target viable.
  • Refused in the same posts: full folding solved; robust long-range contact closure; proof of the entire ToE.
  • Open in the memo: pooled frozen confirmation across both targets; contact recovery still inconsistent; RMSD not decisively significant.
  • Two days later the Villin HP35 R_t post asks a related question (identical snapshot, different fate). Do not collapse v9 RMSD traces onto the Villin AUC number — different harness.

If a ToE is real, it should do more than compress known physics. It should generate a new, testable organizing principle in a domain it was never built for.

Restricted

On the posted 1UAO and 1L2Y traces, frozen bridge-patch v9 improved backbone / angle ordering and moved RMSD in the right direction versus baseline. This is a pre-classical ordering effect in a small-protein harness. It is not native folding, not contact closure, and not a TOE confirmation.
