π₀.₅ source conditional-flow sensitivity pilot: view_large

Completed source-fresh1000-update target-only IDM pilot, B32, seed42/draw seed170013. Raw999/non-EMA: native51 leaves,43 original-source FP32 trainable leaves and8 frozen projections. Original source-wrist23 leaves are appended for inference; deployment74 restores as BF16. Weights, source normalization, exact controller/source-bank/plan/journal and strict export proof are included. Native full Adam/EMA states remain preserved at the training server.

All10 logical collection lineages per suite (40 total) are eligible; eight windows per suite are drawn without replacement each update. All1000 draws and initialization match the full-probe fixed1:1:1 control; the first25 native metrics match with the predeclared tolerance.

The first25 updates use1:1:1. At25,75,…,975 a source-initialization JVP scores the actual detached native post-Adam proposal divided by its actual LR. A fixed40-frame target bank uses two source-noise paths per frame and native denoising anchors1/5/9. The first decision averages fiveB8 groups; later decisions cycle one group. Translation/rotation/gripper are equally weighted after fixed source-RMS normalization. Qref is the minimum of the first three module risks; bias-corrected logEMA(.9) produces sqrt(Qref/Q), bounded[.01,20].

Source-initialization conditional-flow JVP of the actual detached native post-Adam proposal divided by actual LR, on a fixed target-observation/source-noise bank. Current adapted parameters are not consumed by the measurement. FP32 masters with BF16 internal operations give an autodiff proxy, not the derivative of deployed quantization; this is not a policy-retention oracle. Module-specific causality is unestablished without the reserved scalar control. Source observations and scalar-loss/success allocation feedback are absent. Exactly1000 native backward calls and1000 commits occur; extra JVP forward compute is not matched by the fixed control. The first decision checks zero/repeat/doubled numerical controls and hashes native state before/after; later decisions rely on the immutable pure measurement implementation rather than separate whole-state hash witnesses.

Matched seed7 screen: 94/400 (23.50%), four suites x ten tasks x ten official initial states, errors0, process cleanup verified,16 clients/GPU, MuJoCo3.2.3.

Completed pilot comparisons: ur5e: fixed 167/400 → source-flow 0/400 (-41.75pp), view_large: fixed 117/400 → source-flow 94/400 (-5.75pp), yaw30: fixed 201/400 → source-flow 241/400 (+10.00pp). Shared stochastic policy-server streams; episodewise policy noise is not matched across methods. These single400 screens do not establish general improvement, manipulation-knowledge retention or a module-allocation causal effect. Scalar replay is a separate reserved comparison; no larger policy confirmation is included. The legacy export all111 tag identifies parameter layout only.

wam_ctxpool_bmethod

Hyeonmo Kang

Wan2.2-TI2V-5B video DiT + 48-joint action head, trainingmode=joint. The base is suhyeok's finalized B-method recipe: a teacher-forced (sigma=0.25) self-EMA teacher plus an iBOT prototype loss at L18 L18, gamma=0.01, two-view. On top of it the 3 PAST cond latent frames are pooled into one motion frame before a chosen block. These are NOT the surrogate ctxpool runs. The surrogate line (older base, pd8 x GA1) lives in hmkang/wamctxpoolxattn and hmkang/wamctxpoolavg. Do not compare across the two sets. Geometry: 4-latin (numframesin=25, numframesout=41, fdf 2) = 4 cond + 2 future latent slots, 96 tokens per latent frame, 576 tokens per row. Effective batch 16 clips x GA 2 x 2 views = 64 rows…

microduck-bubu-sprint

Dadudu

Own lineage: PPO from scratch (nb1, commit 46c48b1) continued as nb2 and nb4 (commit fac88cc), checkpoint 850 (1.328 s); evolution strategies on the weights against the Arena sprint scorer (0.952 s); then the network frozen and wrapped in a step counter carried in the headroll action that adds joint-target and forward-command offsets from about 0.5 m to the line, found by CMA-ES on the event's official seeds: 0.940 s. No other entry's weights used. Simulation only. A perpetual policy for the microduck (61-D observation, 14 actions, 50 Hz). Runs until told otherwise — a gait, loaded into a policy slot. The observation normalizer is baked into policy.onnx; feed raw observations. manifest.json…

EgoSteer-3B-RealMan

EgoSteer

EgoSteer-3B-RealMan is the generalist policy from EgoSteer: A Full-Stack System Towards Steerable Dexterous Manipulation from Egocentric Videos. It is a world-model-enhanced Vision-Language-Action (VLA) policy built on a Qwen3-VL backbone with a flow-matching action expert, post-trained from EgoSteer-3B-Base on real-world demonstrations collected on the RealMan robot. This is a robot-ready dual-camera (head + chest) checkpoint, corresponding to EgoSteer-9.6K-DG in the paper. For the base model to fine-tune on your own data, see EgoSteer-3B-Base. Our full-stack system integrates EgoSmith (data pipeline), Robot Stack (deployment), and EgoSteer (policy) to learn from 9.6k hours of large-scale…
