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.

Merging the bootstrap into each Proxy's cloud-config was the wrong
mechanism twice over. Detection only matched a literal #cloud-config
first line, so a jinja template or a MIME archive still fell back to
vendor-data, where cloud-init's default mergers drop it — the exact
failure the merge existed to prevent. And the YAML round-trip re-typed
unquoted scalars: version: 1.10 reached the guest as 1.1, comments were
dropped and keys reordered.
Neither is worth patching, because vendor-data delivered as a shell
script bypasses the merger entirely: cloud-init hands vendor-data to its
own handler chain, writes scripts to a separate directory and runs them
from cc_scripts_vendor, after the user's packages and before the user's
runcmd. The merge could not have been rescued anyway — merge_how in
user-data governs only the first source, and merge_how in vendor-data is
discarded before the document is stored.
The Proxy's cloud-init now reaches the seed byte for byte in any format.
installGuestAgent (default true) turns the script off; a configured
vendorData travels beside it as a MIME multipart, declared text/plain so
cloud-init re-sniffs it and this code never classifies user content.

The kvm-ssh Secret is mounted optional, but kvm.New read the key and
known_hosts eagerly and registry.Build aborts the whole provider set on a
constructor error, so a missing or misnamed Secret exited the manager
before any controller started and took the kubernetes and gcp providers
down with it.
lazyAuth loads the material on the first connection and caches it once it
works, so a Secret created after the manager starts heals the affected
proxies on the next reconcile with no restart. A missing file classifies
transient for that reason; a key that does not parse is permanent.
New still checks both files and logs a WARNING: line when they are
unreadable, keeping the startup diagnostic the eager load was there for.

A host name is pasted into the providerID hosts/<name>/domains/<vm>, which
parseProviderID splits on "/", so a name containing a slash produced an ID
that never parsed again: Get, Delete and GC all failed permanently and the
VM leaked with the Proxy's finalizer stuck.
The image map key has the same defect and lands in a file name rather than
an ID: base-<key>.<format> in the host's storage pool. Both now have to
match a plain identifier pattern. Machine-type keys are left alone; they
are only ever compared, never embedded.

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.

In the kind cluster two KVM Proxies with real cloud-configs booted fine
but never left Provisioning: the guest agent was not installed, so the
provider could not learn the IP. cloud-init merges vendor-data under
user-data with its default mergers, which keep the user-data's value
for any key both define and never append lists, so a cloud-config with
its own `packages:` silently dropped the vendor-data's packages and
runcmd. The integration test passed only because its user-data was
empty.
withGuestAgent now appends qemu-guest-agent to `packages` and the
enable command to `runcmd` of the Proxy's own cloud-config (skipping
entries already present) and re-renders it. Vendor-data is no longer
defaulted; `vendorData` is plain extra data. User-data that is not a
cloud-config document (script, #include, MIME) still gets the bootstrap
as vendor-data. A cloud-config that is not a YAML mapping, or whose
packages/runcmd is not a list, fails the Proxy as ErrPermanent.
Validated in-cluster: both Proxies Ready and healthy in two minutes, 204
through squid from the LAN. Docs, sample comment, CHANGELOG and the
plan execution log (Run 7) updated.

docs/kvm-provider.md walks through key generation, ssh-copy-id,
ssh-keyscan under the address the operator dials, and the Secret from
the private key plus ~/.ssh/kvm_known_hosts. make kvm-ssh-secret runs
the same as an apply with KVM_SSH_KEY / KVM_KNOWN_HOSTS overrides and
refuses a .pub, the classic mistake. README mirrors the short form.

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.

The first live run showed the trace working but noisy: testr printed
ts/level/msg and the per-run constants on every line, the error text
appeared twice, host appeared twice on image-cache lines, and the Go
method name was less useful than the libvirt function it maps to.
The tracer now logs rpc=virDomainLookupByName (go-libvirt's names are the
public API names without the vir prefix), error plus libvirtError (code
name) and libvirtCode, and image.go stops re-adding host. The integration
test replaces testr with a compact logr sink: time, logger name, the rpc
as headline, then fields, with provider/host/name omitted since the first
line of the run states them. Docs and execution log updated.

A tracingAPI decorator wraps the 17-method libvirt seam and logs one
"libvirt call" line per RPC after it returns: method, the identifiers it
was given, curated results, duration, and on failure the error with its
libvirt code, name and message. At V(2) the same line carries the domain
and volume XML, metadata and addresses; upload bodies are never logged.
The pool applies it in call() when V(1) is enabled and logs connect,
dial-failure and drop events, taking the caller's logger explicitly like
every other helper in the package.
The integration test installs a testr logger at KVM_TEST_LOG_LEVEL
(default 1) so the trace interleaves with t.Log output, which also ends
the "log.SetLogger(...) was never called" warning. Docs gained a Logging
section and the test env var; the KVM provider execution log records run
4 (guest hang at GRUB) that prompted this.

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.
