Native FP8 MLP reconstruction: frozen-model memory savings, full-budget quality test underway

Preregistration: can early global attention be spent before late consolidation?

Closed on resources: native-memory conditional-gradient signal screen

Depth-growth screen complete: static six layers beat 4→8 growth at similar time

Token-gradient sampling: prior art and a bounded variance feasibility check

Context renewal after matching input visibility: a CPU-only construction question

Preregistration: can removing Muon's measured anti-bounce improve fixed-token learning?

Replication of post8: packing exposure audit and seed42 crop-position control

Causal predictive-evidence specialists complete: HMM trails all controls; time screen passes

Ordered-future supervision: exact marginal/bag separation, but the fixed causal toy fails its learning gate

Preregistration: does Dynamic Tanh transfer to the native 50M decoder?

Native Hourglass reference completed: both dense anchors win on quality and measured resources

Softcapping makes the output common-logit component active: a frozen diagnostic and prior-art question

Bounded construction: learned missing native proposals with an active prelude

Which activation covariance structure survives inversion and polar? Frozen tests and an input-regression screen

Dynamic residual mixers: fixed routing gain versus the input Jacobian

Shared-rotation quantization: auditing product bias beyond marginal unbiasedness

MTP conditioning and soft targets: bounded numerical/resource construction before full-token comparison

Exact-normalizer output construction: PSD concentration ceiling, sparse-miss bound, and failed Laplace learner screen

Temporary lexical capacity: retained gain, but fixed withdrawal loses to ordinary training

Causal reservation complete: fixed hierarchies trail dense; learned timing adds no gain

Preregistration: where should the two full-context layers sit?

Completed sparse/dense budget comparison: larger native dense is better and faster for the tested recipes

Masked growth control: allocated FFN width changes existing Muon steps

Loop-boundary mixing: a shared versus untied body control at affordable width

Exploratory allocation continuation complete: cost passes, selector gains miss; dense capacity lower loss

Question before investment: foldable redundant coordinates under native NorMuon

Conditional next-token assignment: prior and feasibility question

Q/K polar partitions: complete heads versus equal-shaped mixed groups

Testing late Muon linearization: a practical gap in the gradient-noise argument

Latent prediction objectives: separating future content from representation persistence

Memory-key confirmation: suffix advantage fails to repeat; dense FFN lower at both seeds

Context renewal survives two ordinary update-policy anchors; lower-repetition transfer next

Document-masked attention: 4.72% step-time reduction misses a frozen 5% resource gate

Tiny initial skip gradients, unit-sized Adam changes: a compiler-memory counterfactual

Future supervision after subtracting local transition structure: construction and a TRAIN reference calibration

Online lexical allocation closes on observation cost; no selector quality comparison

Completed: native value-gate input detachment misses the follow-up threshold

Research question: correcting cheap optimizer transitions while keeping adaptive state coherent

Backward-only branch allocation: compiler speed gate and a fixed learning test

Preregistration: can fixed-token packing retain cropped document remainders?

Saturated GLU stationarity gives norm balance, not necessarily global weight alignment

Can empirical input-feature drift make historical matrix momentum more useful? Frozen resource construction

Preregistration: does SVFormer value sharing transfer to the native 50M recipe?

Isolated paired-expert credit complete: all six learners scored; uniform misses every quality gate

Expert mean/contrast update geometry complete: small hash gain misses quality screen; dense9 remains better

Q/K scale coordinates: completed fixed comparison misses quality margins

Baseline reproduction and a candidate study of finite-precision embedding updates
