The GPU Is a Queue
A day with 135 GPU jobs and 34 failures, none of which needed the GPU to find. The fix is not a faster GPU, it's treating the card as a shared, budgeted resource with a preflight step before anything touches it.

Krea 2 Wins the Background
Krea 2 won the background task 2 to 1 because it followed the empty-space instruction. Z-Image stayed sharper and faster, so the choice depends on the job.

Publishing Without Publishing Yourself
361 commits in mojo-baro's history carried a private email address that is invisible in every checkout of the repo, because it lives in commit metadata, not tracked files. The Android repo separately carried 112 MB of committed build output. Neither would have been caught by reading the code.

Keeping the Failures In
BARO_SPEC defaults to on. Setting it on the MoE model changes nothing, because the actual gate in the code is BARO_SPEC and a model flag that is always false for that architecture, and the document says so in the same line rather than in a footnote.

int8 WMMA Is Not Faster
v_wmma_i32_16x16x16_iu8 issues at 1.007x the rate of the bf16 WMMA instruction on gfx1100, both at 133 T-ops/s. An int8 MMQ prefill kernel built on the expected 2x lost to the project's own bf16 kernel, 0.91x at n=1024, and the lane closed negative.

A Model File That Carries Its Own Kernels
Two bakes of this project's models pass a from-the-file rebuild and gate, 64 of 64 tokens, with no checkout and no external fixture. A third, earlier bake of the same champion model claimed the same thing and was lying: its verify path had quietly fallen back to a local fixture instead of reading its own embedded evidence.

The IPC Primitive Is a Latent Tensor
An OS design in which the message between agents is a latent tensor with an identity, and text is one adapter among several. The transport and tiering numbers are real, the fork gate is resolved, and the thesis experiment has not passed. That experiment asks whether an untrained model reads its own hidden states as reasoning.
