* fix(ssh): persist sandbox host identities
Store each sandbox's Ed25519 host key in the gateway credential store and
deliver it only to the supervisor. Preserve identity across restarts,
delete owned credentials with the sandbox, and expose the public SHA256
fingerprint through sandbox and SSH-session APIs and client SDKs.
Cover credential ownership, cancellation, deletion retries, client
compatibility, and pinned SSH connections through lifecycle transitions.

When the gateway exports OTLP traces, compute drivers pass the gateway's
endpoint to supervisors as OPENSHELL_OTLP_ENDPOINT, along with TRACEPARENT
from the operation that launched them. The Kubernetes, Docker, Podman, and
VM drivers all receive the endpoint from the gateway; driver TOML cannot
set it. On Podman Machine, the Podman driver points a loopback endpoint
at host.containers.internal, since supervisor loopback is the VM's.
The supervisor exports spans as openshell-supervisor, tagged with
the sandbox ID, and flushes them before exiting.
supervisor.startup joins the sandbox's creation trace and covers image
policy discovery, policy load, and boundary attach, confirm, agent start,
and access start. Supervisor calls to the gateway carry W3C trace context,
so the gateway's server spans nest under them.
Each egress connection emits supervisor.egress.connect with authorize,
resolve, and dial children. These spans use DEBUG level because every
outbound connection starts its own trace. OpenShell spans export at INFO,
or at the sandbox log level when it is debug or trace; spans from other
libraries export at INFO.

* feat(server): write gateway OCSF events to JSONL
Previously, gateway security activity was available only in diagnostic output,
and events not associated with a sandbox, such as TLS certificate reloads, had
no independent structured record.
Now, configuring `openshell.gateway.ocsf_log` writes every gateway-produced
OCSF record to a bounded JSONL destination independently of `RUST_LOG`. The
destination supports daily or disabled rotation, retention limits, queue bounds,
and optional schema downgrade to OCSF 1.1 or 1.3.
Additionally, existing gateway emitters (TLS reloads, service routing, and
policy approval and auto-approval audits) emit structured events, so they reach
the JSONL destination, console shorthand, and the affected sandbox's log
stream. Records identify the gateway by its configured name in `device.uid` and
`device.name`, shared across replicas, with `device.hostname` identifying the
replica and `device.os` the gateway's operating system. Metrics and warnings
expose known best-effort losses.

* feat(driver): default to numeric non-root identity for USER-less images
With the default sandbox image now Alpine, images that declare no OCI USER
must start instead of being rejected. When the image declares no USER and
the policy requests none, the Podman and Docker drivers now supply a numeric
non-root identity (DEFAULT_SANDBOX_UID/GID = 1000) instead of rejecting,
matching the numeric-identity behavior of the Kubernetes and VM drivers. The
supervisor's resolved-identity path runs the sandbox as a synthesized
non-root account without the account existing in the image. Images that
declare a USER keep the OCI resolution path unchanged.

Centralize compute-driver RPC descriptors, stream instrumentation, provider
routing, and standalone installation in openshell-otel. Use typed RPC
constants so gateway and in-process driver paths cannot panic on unknown
operation strings or repeat runtime method parsing.
Emit semantic-convention rpc.service and rpc.method attributes, preserve
trace context and resource identity across deployment modes, and route both
RPC boundary and backend crate spans to each selected driver provider. Leave
consumer-dropped watch spans unset while recording observed terminal status,
and avoid reboxing untraced external-driver streams.
Derive each driver tracing identity from Cargo package and crate metadata and
attach its descriptor to the compute-driver registration, keeping provider
selection and target routing tied to the registered implementation. Share
tracing setup and round-trip test support across Docker, Podman, Kubernetes,
and VM, and update the gateway tracing documentation.

* feat(vm): support corporate HTTP forward proxy egress for microVM sandboxes
The corporate forward proxy machinery from #1792 is driver-agnostic and
already merged: openshell-supervisor-network implements CONNECT chaining,
NO_PROXY matching, credentials, https:// proxies and corporate CA trust, and
openshell-sandbox exposes it as six argv-only flags. Podman gained the driver
half in #2245/#2512 and Kubernetes in #2633; the VM driver had none of it, so
VM sandboxes on proxy-only networks could not reach any destination requiring
the proxy even when policy allowed it.
The blocking piece was not proxy logic but delivery: the VM guest init script
runs as PID 1 and execs a fixed supervisor command line, and libkrun's
krun_set_exec receives an empty argv, so there was no channel for driver-owned
supervisor arguments. The supervisor's proxy flags deliberately have no
environment fallback, and build_guest_environment merges user-supplied
environment, so the guest env is not a safe transport either.
Add a driver-authored argument file, mirroring the existing init.d manifest:
the driver writes /opt/openshell/supervisor-args into the overlay upperdir on
every launch and the guest reads it verbatim, one argument per line, appending
it to every supervisor exec. It is written even when empty, which is what makes
the channel unforgeable -- the upperdir always shadows the read-only image
layer, so an image can neither supply its own arguments nor disable the
operator's by omitting the file. Because both launch backends exec the same
init script, this covers libkrun and QEMU without touching either.
A microVM has no bind mounts or container secrets, so the credential and CA
bundle are staged into the per-sandbox overlay the way the gateway JWT already
is: credential root-only at 0600, CA at 0644, both rewritten every launch so a
removed setting clears prior material, and both deleted with the sandbox state
directory. This places the credential at rest in the overlay image on the
gateway host, which differs from the Podman secret model and is documented as
an explicit security consideration.
Validation is fail-closed and shared: a new
openshell_core::driver_utils::validate_upstream_proxy_settings holds the
pairing rules the Podman driver established, and both the gateway and the
driver call it so an invalid table names the offending key instead of
surfacing as an opaque driver-readiness timeout.
Guest egress leaves through gvproxy, so a proxy on the gateway host's loopback
is reachable only through host.openshell.internal; the guest to gateway
callback is unaffected.

* fix(vm): bound the proxy CA read and scope the host-loopback recipe
Two review findings on the corporate forward proxy support for microVM
sandboxes.
The driver read the operator's proxy_ca_bundle with an unbounded fs::read and
accepted it on a substring match for the PEM BEGIN CERTIFICATE marker. A
special file such as /dev/zero therefore grew driver memory without bound on
every authorized sandbox create, and a PEM block holding invalid DER passed
the host check but contributes no trust anchor in the guest, so every
supervisor would fail after boot with an error attributed to the sandbox
rather than to the setting.
Move the read into openshell-core as read_upstream_proxy_ca_bundle_file: it
reuses the credential reader's bounded-read path (non-regular files rejected
on fstat, size capped, read bounded even if the file grows), then requires at
least one anchor that RootCertStore::add_parsable_certificates accepts. The
supervisor's own reader now delegates to it, so host acceptance and guest
acceptance are the same function and cannot drift.
The published host-loopback recipe was written for libkrun only. gvproxy NATs
host.openshell.internal to the gateway host's 127.0.0.1, but GPU sandboxes run
on the QEMU/TAP backend where that name resolves to the TAP host address and
the driver's own nftables input chain accepts only the gateway port from the
guest — no proxy on the gateway host is reachable there at any bind address,
so an operator following the generic recipe lost all proxy-required egress
while configuration validation succeeded.
Scope the recipe to libkrun in every reference and reject a gateway-host proxy
URL when a launch plan resolves to QEMU, naming the reason, instead of booting
a sandbox whose policy-approved CONNECTs all time out.
Signed-off-by: Philippe Martin <phmartin@redhat.com>
* fix(vm): match the QEMU proxy preflight to the selected TAP host
The gateway-host proxy guard added for the QEMU/TAP backend classified the
wrong set of addresses in both directions.
It ran at the top of configure_qemu_launch_plan, before the subnet allocation
that settles plan.host_ip, so it could not compare against the address the
guest actually reaches the host on. An operator pointing https_proxy at the
sandbox's own TAP host address, such as 10.0.128.1, passed the check, and the
driver's nftables input chain — which accepts only the gateway port from the
guest — then dropped every policy-approved CONNECT, which is exactly the
silent timeout the guard exists to prevent.
In the other direction it rejected 192.168.127.254 unconditionally. That
address is special only to libkrun/gvproxy; on QEMU/TAP it is an ordinary
address that may be routable through the guest's masqueraded egress, so the
guard refused a working configuration.
Run the check after the launch plan's network allocation, on both the
freshly-allocated and already-complete paths, and compare IP literals with
that sandbox's selected TAP host. Loopback literals, localhost, and the
documented host aliases that write_host_gateway_aliases seeds to the TAP host
still classify as the gateway host, and the failure names the address. The
gvproxy host-loopback constant returns to being a documentation anchor.
