* feat(sandbox): log connection attempts that bypass proxy path
Add iptables LOG + REJECT rules inside the sandbox network namespace to
detect and diagnose direct connection attempts that bypass the HTTP
CONNECT proxy. This provides two improvements:
1. Fast-fail UX: applications get immediate ECONNREFUSED instead of a
30-second timeout when they bypass the proxy
2. Diagnostics: a /dev/kmsg monitor emits structured BYPASS_DETECT
tracing events with destination, protocol, process identity, and
actionable hints
Both TCP and UDP bypass attempts are covered (UDP catches DNS bypass).
The feature degrades gracefully if iptables or /dev/kmsg are unavailable.
Closes#268
* chore: track .python-version to pin Python 3.13.12 for uv
The sandbox base image runs Python 3.13. A stale venv on 3.12 causes
all exec_python E2E tests to fail because cloudpickle bytecode is not
compatible across minor versions.
* fix(cluster): preserve hostGatewayIP across fast deploys
The fast deploy's helm upgrade was missing the hostGatewayIP value that
the bootstrap entrypoint injects into the HelmChart CR. This caused
host.openshell.internal hostAliases to be lost from the gateway pod
and sandbox pods after any fast deploy, breaking host gateway routing.
Read the IP from the HelmChart CR and pass it through to helm upgrade.
* wip: fix iptables path resolution, use dmesg for kmsg, add CAP_SYSLOG
* fix(sandbox): restore NetworkNamespace Drop impl, remove dead kmsg code
The Drop impl for NetworkNamespace was accidentally deleted during the
bypass detection refactor, which would cause network namespaces and
veth interfaces to leak on every sandbox shutdown.
Also removes dead kmsg volume/mount code (bypass monitor uses dmesg
instead of direct /dev/kmsg access) and removes an accidentally
committed session transcript file.
Closes#273
Verify inference endpoints synchronously on the server during set/update, expose a --no-verify escape hatch in the CLI and Python helper, and return actionable failures when validation does not pass.
* feat(sandbox): inject host gateway hostAliases into sandbox pods
Sandbox pods running in the k3s cluster cannot resolve host.docker.internal
by default, preventing them from reaching services on the Docker host.
Detect the host gateway IP (default route) in the cluster entrypoint,
thread it through the Helm chart to the gateway server, and inject
hostAliases entries (host.docker.internal, host.openshell.internal)
into every sandbox pod spec. The injection is conditional -- when the
IP is empty (non-Docker deployments), no hostAliases are added.

Compute version strings from git describe in openshell-core's build.rs
using the guess-next-dev scheme (e.g. 0.0.4-dev.6+g2bf9969). All binary
crates and the TUI splash screen now use the shared openshell_core::VERSION
constant instead of CARGO_PKG_VERSION.
In Docker/CI builds where .git is absent, falls back to CARGO_PKG_VERSION
which is already set correctly by the sed-patch pipeline. Also adds
OPENSHELL_CARGO_VERSION support to the cluster image and fast-deploy
supervisor builds for parity with the gateway.
* feat(sandbox): add gpu sandbox scheduling support
Allow sandbox creation to request GPU resources explicitly or infer them from GPU image names. This wires GPU intent through bootstrap, validates gateway support, and adds dedicated GPU E2E coverage for follow-up cluster testing.
