CapyCTL 0.1.1

CapyCTL 0.1.1

TensorFold

CapyCTL now runs TensorFold 0.6.0 and 0.6.1 beside vLLM and SGLang. Register an existing
TensorFold venv with capyctl engine add <venv>, or name it as the role's own
engine with --tensorfold-bin (CAPYCTL_TENSORFOLD_BIN, local_engine.tensorfold); CapyCTL checks that the CUDA
build tools TensorFold needs on its first start are on the engine's PATH. With
0.6.1 the CUDA compiler can come from pip (pip install ninja "cuda-toolkit[nvcc,cccl]==13.0.*") instead of a system toolkit.
TensorFold models do not park: CapyCTL stops them when it needs the memory and
starts them again on the next request. A TensorFold deployment states its
resources and context_length. Checked on NVIDIA GB10; discrete GPUs run it
unchecked in this release.

Other changes

• A readiness check now accepts a model that answers with reasoning first.
• New exit code 26, toolchain_missing, from capyctl engine add.
• A client that hangs up in the middle of a streamed answer now stops the
  engine's work on it, for vLLM, SGLang and TensorFold. CapyCTL keeps the
  request counted until the engine reports nothing running or waiting, so a
  park or a switch that follows no longer waits for the whole answer. A
  client that reads nothing for 10 seconds, and a single piece of an answer
  larger than 64 KiB, now end the answer the same way; before, the engine ran
  the answer to its end.
• A model named by its Hugging Face cache directory (snapshots/<rev>) is
  measured even when its files link twice, as recent huggingface_hub
  versions store them. A checkpoint that cannot be measured now says why,
  instead of reporting a digest mismatch.
• capyctl validate config without --host checks a resources block and
  refuses a TensorFold deployment without one, and lists what still needs a
  host.
• A role with no engine starts and says how to add one; capyctl engine remove can remove the last engine.
• capyctl status deployment shows the engine a deployment actually runs, with a note
  when that engine is no longer registered.
• Idle models are stopped or parked only when ready_idle_timeout or
  parked_idle_timeout is set; both are off by default.
• CI is a fast gate; the integration suites run with scripts/ci-local.sh --deep
  before a merge, and tests no longer depend on runner speed.

Upgrade

Replace the binary and restart the roles; 0.1.0 state is reused.
