> Watch the test51 farm live through Tide ocean: three nodes sweeping Welvet train modes while Lucy Score and LPD measure learn-while-serve density.

Watch the farm think
Three boxes are sweeping Welvet train modes under live load. This page explains what
Lucy and LPD mean, and whether the farm is up —
then hands you the live ocean board (proxied over this site).

What we look for
Tide on GitHub
Farm pulse
Is testing running?
Ocean polls each node’s Tide Lucy dash ( :8080 ). If tides answer, the farm is live.

What we are looking for
Not “highest accuracy in a lab vacuum.” We want a net that learns while it still serves ,
then how far that live-fit can shrink into a small RAM box without falling into a trap.
🎯
Acc
Hard argmax accuracy — did it actually learn? The Acc champion is the RAM reference for density.
⚡
Throughput
Outputs per second while the sweep is live. Actions under load, not a frozen train loop.
🟢
Availability
InferMs / (InferMs + TrainMs) . Duty cycle: can you still talk to the model while it trains? SGD that blocks serve dies here.
Metric Meaning
Lucy Score Throughput × Availability × Acc / 10,000 — live-fit. SoftAcc is serve-confidence, not this term.
LPD (Lucy density) Q × shrink vs Acc-champ RAM. 0 unless Acc keep ≥ 70% (weeds Score/MiB traps).
Gold All three pillars ≥ 80% and RAM ≤ 20% of the Acc champ — trifecta in a small box.
Trap Tiny RAM looking “dense” with Acc keep < 70% (chance Acc / binary traps).
Measuring math lives in Welvet’s Lucy package; Tide only displays it. See the tide README .
How this is wired
Tide, ocean, and test51
Tide is the open-source serve+train framework ( github.com/openfluke/tide ).
This website imports it and runs ocean mode — a tide-of-tides that does not train;
it polls each node’s Lucy board and consolidates winners.
🌊
Tide (:8080)
Per-node Lucy dashboard. Ocean peers must be these Tide ports — not the harness.
🧪
test51 (:5151)
The think-race harness: trees of mode × layer × dtype × challenge, then LR / cams / grid leaves.

Ocean (here)
Embedded in openfluke.com. Proxied at /ocean/ over the same HTTPS as the site. Peer links go through /tide/… and /lab/… .
Farm split: config1 · config2 · config3 across three machines, each running a different slice of Welvet train modes.

Ocean reporting
Same board the lab uses — served from this site so it works on HTTPS.
