docs/providers.md collects the provider contract that was spread across
comments, callers and per-provider docs: MUST/SHOULD/MAY rules per method,
each tied to the reconciler or GC behaviour it protects, the error taxonomy,
a feature matrix for kubernetes/gcp/kvm with file:line notes, a checklist for
adding a provider, and the known gaps. Linked from architecture.md and
CLAUDE.md.

The health check shares each host's libvirt connection with the reconciles,
so it must not be able to take that connection away from them.
- A timed-out check no longer drops the link. The check goes through the new
hostPool.probe, which abandons its RPCs when the context ends and leaves
the connection alone, so an image upload or a Create running on the same
link is not cut off. A link that really died is closed by the keepalive.
One abandoned probe per host may stay waiting; until it returns, the next
check reports Timeout at once (errProbeBusy).
- Waiting for a host's connection slot now ends with the caller's context.
hostEntry used a mutex, so a check could wait out a reconcile redialing a
dead host — minutes — past its own timeout. The slot is a one-slot channel
and acquire bounds only the wait, never the uncontended take.
- --provider-check-timeout defaults to 0 and derives min(15s, interval).
The flat 15s default contradicted the validation that the timeout may not
exceed the interval, so --provider-check-interval=12s alone failed to
start.

Architecture gets a provider-health section, component rows and four
decisions; the KVM provider doc gets a health-check section with the
reason table and the rotated-Secret gap; the testing guide lists the new
suites. CLAUDE.md's Architecture TODO and stale "only go.mod exists"
gotcha now point at the real docs, plus the RBAC-marker gotcha found
while wiring the monitor.

reconcileDelete asked Get first and dropped the finalizer only on
not-found, so a permanent Get retried forever: a KVM host removed from
the config, or a providerID the provider cannot resolve, left the Proxy
in Terminating with no way out. It now tries Delete anyway, which is
idempotent and can still finish where Get cannot converge, and releases
the object when that succeeds.
crawl.example.com/skip-cleanup abandons the instance for the cases that
stay stuck, such as revoked credentials. It is checked before the
provider lookup, so it also frees a Proxy whose provider is gone from
the config.
In the KVM provider, Delete over an unconfigured host is now a no-op
success, mirroring removeVolumes over a missing pool. Get keeps failing
permanently there on purpose: the live path reads not-found as "rebuild
it", so a typo in hosts must not look like a missing VM.

The known-gaps entry, decision log, sample comment and builder comment
blamed the host; the cause is trixie's GRUB config ("terminal_output
gfxterm serial" with a serial console and no video device), reported
and reproduced upstream and still open. UEFI remains the default for the
reason recorded; bookworm images are noted as unaffected.

Run 5 on the real host bisected the guest hang: the Debian 13 image
hangs after GRUB under SeaBIOS with or without our seed and with either
CPU model, and boots under OVMF. The image's legacy boot chain is the
problem, not the provider.
images.<key>.firmware is "uefi" (default) or "bios". The domain XML
emits <os firmware="efi"> with secure boot off, so libvirt selects the
OVMF binary and manages the NVRAM file, which the existing nvram undefine
flag removes. Direct-URL images default to UEFI too. OVMF joins the
hypervisor prerequisites; sample, config table, known gaps, decision log
and the execution log record the finding.

Registers "kvm" in the provider builtins, mounts an optional kvm-ssh
Secret at /etc/proxy-operator/kvm, adds a kvm-home providers-config
sample and a proxy_kvm.yaml Proxy sample, documents the provider in
docs/kvm-provider.md (prerequisites, config reference, image cache and
its do-not-replace-in-use rule, known gaps), and updates the README
and architecture provider sections and decision log.
