IvanHunters 318be935ca fix(e2e): capture Talos logs for tenant worker join failures (#3548)
## What this PR does

Addresses #3513.

When tenant Kubernetes workers miss the 18-minute Ready deadline, the
E2E runner now mints a one-hour `os:reader` Talos client certificate
from the tenant's existing issuer and runs authenticated `talosctl` from
a hardened same-namespace diagnostics Pod. It captures bounded `dmesg`
and kubelet output for every worker VMI in the cozyreport snapshot,
records missing IPs and command exit codes, continues across unreachable
workers, and preserves the original test failure.

The diagnostics Pod has no service-account token or Secret volume;
credentials are streamed into an `emptyDir`, and the Certificate,
Secret, and Pod are labeled for cleanup. Workers that have not reached
Talos `apid` can only yield a bounded connection error, while workers
that reached `apid` provide guest logs. This adds the evidence needed to
distinguish the remaining guest boot failure but does not claim to
resolve its underlying cause. The readiness budget and success path are
unchanged.

Because this changes a shared E2E helper, test-impact analysis selects
the full E2E suite for this PR.

Not applicable; no UI changes.

### Testing

- `hack/cozytest.sh hack/run-kubernetes-talos-diagnostics_test.bats` (10
tests)
- `hack/cozytest.sh hack/run-kubernetes-drain_test.bats`
- `hack/cozytest.sh hack/cozyreport-talos.bats`
- `bash -n hack/e2e-chainsaw/_lib/run-kubernetes.sh`
- `git diff --check origin/main...HEAD`

The full `make bats-unit-tests` run reached the unrelated
`hack/migration-seaweedfs-db-adopt.bats` suite and could not continue
because Docker is unavailable in the development environment. A live
failure-path run was not performed because the available development
environment has no Talos tenant fixture; this PR is intended to exercise
that path in Cozystack CI.

Aleksei Sviridkin 0dae3ca95a fix(e2e): budget tenant scheduling separately from workload readiness (#3579)
## What this PR does

The tenant backend Deployment in the kubernetes suites had one 300s
budget to reach `condition=Available`, and two unrelated variable costs
shared it.

The first is scheduling. What the suite establishes before that point is
two tenant nodes Ready, which is weaker than schedulable: a Ready node
still carries `node.cilium.io/agent-not-ready` until the tenant cilium
agent claims it, and a node the bringup has not finished with is
`SchedulingDisabled`. In the run recorded in #3577 scheduling took 2m18s
and 1m57s in the two suites, which left the image pull to finish inside
what remained. It did not, and both suites reported the same `timed out
waiting for the condition` for what were two different shortfalls.

So this waits for a node that actually accepts a Pod before creating the
workload, on its own budget and its own failure message. The gate
encodes the scheduler's rule for a Pod that tolerates nothing (Ready,
not unschedulable, no `NoSchedule` or `NoExecute` taint) over a
`custom-columns` probe, prints the node table on both outcomes so a
timeout names the taint that held it, and treats a failed probe as
not-schedulable so an API blip cannot release it. On the happy path it
adds no wall time: it spends the seconds the Pod would otherwise spend
Pending, plus at most one 5s poll interval. On a failing run the two
budgets stack, so a run that exhausts both now gives up at ~600s where
it used to give up at 300s, inside the 40m Chainsaw script op the suites
document as a ~25m bringup. The readiness wait keeps its 300s, now
starting from a schedulable node, and dumps deployment, pod and event
state when it runs out.

The workload image is also pinned by digest. The tenant workers reach no
Docker Hub mirror (`hack/e2e-talos-image-cache.yaml` serves the Talos
worker OS disk image over HTTP and is not a registry mirror), so nginx
is pulled from Docker Hub on every run either way. The digest does not
take the pull off the critical path; it fixes what that pull returns
instead of leaving a floating tag free to change size and content under
a fixed deadline. Preloading the image would need infrastructure this
tree does not have, and is not attempted here. Nothing will bump the
pin: no renovate manager reads `hack/`, and the comment says so, because
for a throwaway test workload the freeze is the point.

What this does not claim: it removes two measured consumers from a fixed
budget, both taken from the events of a single run. Whether that budget
was the only thing making those suites red is not established from one
run, so this is not offered as the fix for a red pipeline.

`hack/run-kubernetes-schedulable_test.bats` covers the new logic: every
branch of the predicate, the multi-node scan, the poll-again path, the
deadline, and a probe that fails. Each test was verified by mutating the
helper and checking that the intended test, and no other, went red.

Note for whoever reviews alongside #3575: that branch mirrors `ghcr.io`
for tenant worker pulls, not `docker.io`, so it does not change the
Docker Hub pull described here. `git merge-tree` reports no conflict
between the two, nor with #3548.

Observed in #3577.

Aleksei Sviridkin 5542ae52b7 fix(e2e): budget tenant scheduling separately from workload readiness
The tenant backend Deployment had a single 300s budget to reach
condition=Available, and two unrelated variable costs shared it. The
first is scheduling. What the suite establishes before that point is two
tenant nodes Ready, which is weaker than schedulable: a Ready node still
carries node.cilium.io/agent-not-ready until the tenant cilium agent
claims it, and a node the bringup has not finished with is
SchedulingDisabled. Scheduling took 2m18s and 1m57s in the two tenant
suites of one run, leaving the image pull to finish inside what was
left. It did not, and both suites failed with the same message for two
different shortfalls.

Wait for a node that actually accepts a toleration-free Pod before
creating the workload, on its own budget and its own failure message.
The gate encodes the scheduler's rule for such a Pod (Ready, not
unschedulable, no NoSchedule or NoExecute taint) over a custom-columns
probe, prints the node table on both outcomes so a timeout names the
taint that held it, and treats a failed probe as not-schedulable so an
API blip cannot release it. The readiness wait keeps its 300s, now
starting from a schedulable node, and dumps deployment, pod and event
state when it runs out.

Pin the workload image by digest. The tenant workers reach no registry
mirror, so nginx is pulled from Docker Hub on every run either way; the
digest fixes what that pull returns instead of leaving a floating tag
free to change size and content under a fixed deadline.

Aleksei Sviridkin 3fc8e524b2 fix(e2e): select catch pod logs by the nested release instance label
The harbor, openbao and qdrant app charts deploy their workload through
a nested HelmRelease named `<release>-system`, and pass
`fullnameOverride: <release>` down to it. The inner chart therefore
stamps app.kubernetes.io/instance from its own release name, with the
suffix, while object names come from the override, without it. The
catch blocks selected on the outer release name, so podLogs matched no
pods and every failed run collected an empty result.

A pod name says nothing about its instance label; the two come from
different sources on purpose. In qdrant the unsuffixed value is
therefore not retired but kept as a collector of its own: the parent
chart's PVC-cleanup Job labels its pod template with the parent release
name, and that suite deletes the parent inside a `try:`, so the Job is
in scope while the test still runs. The comment there is explicit about
how narrow that window is -- the hook always exits 0, so Helm calls it
succeeded and `hook-succeeded` takes the pod away; what is left is an
uninstall that hangs with Helm still waiting on it.

Harbor renders the same hook and does not get the same collector. It
has no `delete` op, so its parent release is uninstalled only in
Chainsaw's cleanup phase, which no catch can observe: catch is a defer
inside the step, while the cleaner runs from t.Cleanup, after the test
function returns. That collector would be the same permanently-empty
capture this commit removes. A comment records the asymmetry so the
next reader does not restore it for symmetry. openbao renders no such
hook at all.

Each workload value is now also pinned on a resource in an assert the
suite already runs, so the chart renaming a label fails a step instead
of quietly emptying a capture. The comments state what that does and
does not cover: it does not catch a wrong value typed into a selector,
and it catches nothing when the run fails before the assert.

Harbor's database was reached by no collector at all. It is selected on
`cnpg.io/cluster`, CNPG's own primary label, rather than on the
instance label CNPG merely derives from the Cluster name -- the primary
label has nothing to drift from, and it is what the postgres suite and
the WorkloadMonitors already use.

Each lookup keeps stderr apart from the value it captures. kubectl exits
0 while logging a klog line about an API group it could not reach, and
an aggregated APIService in that state is what a failed run usually
looks like; folded into the value, that line makes the "nothing found"
branch unreachable and prints as though it were a result.

Telling those outcomes apart is one helper in hack/e2e-chainsaw/_lib/
rather than a copy per call site, separated from the kubectl call so it
can be pinned without a cluster, the way etcd-probe.sh already is. Both
the census and the qdrant cleanup listing report through it, differing
only in wording, so the discrimination is implemented and tested once.
The tests cover each outcome for both wordings, including the zero exit
with a klog line on stderr -- the case a folded stream turned into a
row.

A collector that matches nothing cannot say so: podLogs is silent, and
`kubectl get -l` exits zero on an empty match. Each test-wide catch
prints the instance label of every pod in the namespace, and the qdrant
cleanup catch reports its three outcomes apart from a single call --
printing what that call returned rather than running it again, which
could put a healthy listing under a failure heading.

That census runs on a degraded cluster, where kubectl otherwise retries
discovery against an unreachable apiserver until something kills the
script, so every lookup carries `--request-timeout`. Measured against an
unreachable apiserver, a bounded call costs about five times the flag,
since kubectl retries discovery five times before it gives up. Each
script then carries an explicit op timeout sized above its own calls --
2m for the single-call censuses, 5m for the qdrant cleanup listing,
which makes three. An inner budget is what should fire: a SIGKILL at the
op boundary yields nothing, where a kubectl that gives up leaves an
error to print.

IvanHunters 0612a538a3 fix(e2e): bound the Talos-capture failure-branch forensic kubectl calls
The describe/get-events/get-certificaterequests calls that run when the
reader Certificate or the diagnostics Pod misses its readiness wait were
unbounded, yet those branches fire precisely when the management apiserver is
wedged. A stalled forensic call there can burn minutes of the 50m step budget
before the pre-existing (a2)/(c) diagnostics and the EXIT-trap tenant
snapshot run. Add --request-timeout=30s to them, matching the happy-path

IvanHunters cfbfd770b8 fix(e2e): bound the tenant Talos capture kubectl calls
The in-guest diagnostics chain runs only when the sandbox is already
degraded enough to miss the 18m node-join deadline (the documented
management-etcd fsync-storm regime), yet its kubectl legs were unbounded
while every talosctl leg is wrapped in timeout. A stalled apiserver call in
the (b) capture could consume the remaining step budget before (a2), (c) and
the EXIT-trap tenant crust-gather run, so a diagnostics feature could reduce
total diagnostic yield under the exact conditions it targets.

Add --request-timeout=30s to the raw Certificate/Pod apply, the three
reader-Secret reads and the worker VMI list, and route the Certificate Ready
wait through kubectl_wait_retry so a single transient etcd-leader flap
retries instead of aborting the whole capture. Update the bats assertion for
the reworded wait call. Also correct a stale comment: the chainsaw step
timeout is 50m, not 40m.

Andrei Kvapil 330acfe6e2 fix(e2e): widen tenant node-join deadline to 18m
The kubernetes-latest and kubernetes-previous suites flaked on the
worker node-join wait under host load. In run 30260770694 both failed at
exactly 12m with zero tenant Nodes registered and the tenant cilium HR
still mid-install: a transient drbd.linbit.com/lost-quorum taint delayed
the worker DataVolume imports, so the KubeVirt VMIs were only created ~2m
into this wait and the guests then had ~10m to import Talos, boot,
register a kubelet and let cilium turn the nodes Ready.

This single deadline absorbs the entire worker bring-up (the
machinedeployment replicas=2 gate clears before the VMIs even exist), so
under storage pressure 12m is too tight. A less-loaded fleet run passed
both suites unchanged, confirming load-induced slowness rather than a
stuck bring-up. Widen the deadline to 18m, which restores margin and
still sits well inside the 40m chainsaw step timeout.

Aleksei Sviridkin 07c67a8913 test(e2e): capture previous container logs and stop killing the snapshot
Root-causing a crash-loop failure was blocked twice over by the
diagnostics collected on failure.

`kubectl logs` shows only the current container instance, so for a
crash-looping pod the suites' `podLogs` collector captured the Nth
restart -- a fresh replay of the same startup path -- while the
evidence that explained the failure sat in the first, interrupted
instance. Chainsaw's podLogs collector has no `previous` option, so
add e2e-capture-previous-logs.sh and drive it from the global catch
and from the BATS failure hook. It discovers containers with
restartCount > 0 at runtime (init containers included, where an
interrupted bootstrap lives), orders the app suites' namespace first,
and dumps each to the job log and the snapshot tree. Containers that
never restarted are skipped, so a healthy run emits one line rather
than a page of "previous terminated container not found".

Every way that capture can come up short is named rather than
inferred, because kubectl exits 1 for a garbage-collected container,
an RBAC denial and an unreachable node alike: the container cap, a
pod list that never returned (which is not the same as nothing having
restarted), a read that timed out versus one kubectl refused and the
reason it gave, and a previous instance that produced no output. A
partial capture is kept and marked truncated rather than deleted --
it is the only copy of a log already gone from the cluster.

The crust-gather snapshot was killed by the Chainsaw op containing it.
A script op is bounded by timeouts.exec (5m), and the catch's own
wall-clock wrappers summed to 960s, so the script was SIGKILLed
partway through -- taking out the process group mid-write and skipping
the data-plane capture entirely. Give each catch op an explicit
timeout above the budgets it contains, so an inner timeout fires
instead and leaves a partial, still-servable snapshot behind. The
data-plane leg drops from 600s to 300s at that call site so both legs
fit one envelope; the BATS hook keeps the wider budget, having no
containing op.

Set crust-gather --duration explicitly as well. It is the collection
phase's own budget, it defaults to 60s, and on elapse it abandons the
collection and skips its finish step, leaving a truncated tree with no
indication anything is missing. The outer wall-clock has to exceed it
because the API discovery that runs first is not covered by that
budget at all -- with an unhealthy aggregated APIService, the state a
failed run is usually in, discovery alone can consume the whole
timeout before a single object is written. Send each collector's
output to a log beside its snapshot instead of /dev/null, with a
complete/truncated/failed verdict, so that question is answerable
from the artifact.

myasnikovdaniil aa707f17b5 test(etcd): stop losing the metrics probe's output to the attach race (#3350)
## What this PR does

The etcd suite's metrics contract failed in CI with `metrics endpoint
did not return 200 over http on the 'metrics' port; got: If you don't
see a command prompt, try pressing enter.`

The probe runs a one-shot curl Pod and reads a `code=<status>` marker
back off its output via `kubectl run --rm --restart=Never --attach`.
`--attach` only establishes its connection once the Pod reaches Running,
so a container that exits in milliseconds — which is what curl against a
Pod IP does — writes its stdout into the void, and `--rm` then destroys
the Pod carrying the log that still held it. The step reports the
metrics endpoint as broken on a cluster that was serving it correctly
throughout.

The evidence that this was output loss rather than an endpoint failure
is that the captured output contained no `code=` at all. A genuine
connection failure would still have printed `code=000` from `-w`, plus
curl's own error text from `-fsS`, and both were being captured.
Meanwhile the probe Pod's events show a clean run, all three etcd
members were up without restarts, and every preceding assert in the
suite passed.

The fix drops `--rm`, re-reads the Pod log when the attach stream
carried no marker, and deletes the Pod explicitly afterwards. This is
the same treatment `hack/e2e-chainsaw/_lib/talos-image-cache.sh` already
applies to the identical race — that probe documents it inline; the etcd
one was simply never given it. A `--pod-running-timeout` is set for the
same reason it is there: the probe image is used nowhere else in the
tree, so it pays a cold pull on every run and kubectl's one-minute
default was a second way to end up with no marker.

The recovery cannot turn a real failure green. The marker encodes the
outcome, so a `code=503` recovered from the log still fails the step; an
attach stream that already carried a marker is never second-guessed; and
the pre-run delete blocks, so a stale Pod's log cannot be read in place
of this run's. Verified by running the probe's exact curl invocation
against a 503 and against a dead port: the first yields `code=503`, the
second `code=000` plus curl's error, and both fail. The probe still runs
exactly once — this is output recovery, not a retry.

Helper extracted to `hack/e2e-chainsaw/_lib/etcd-probe.sh` with unit
coverage in `hack/etcd-probe_test.bats`.

Aleksei Sviridkin 44b221d772 test(kubernetes): size the e2e tenant apiserver to the chart default
The tenant Kubernetes e2e pinned controlPlane.apiServer.resourcesPreset to
the legacy "small" preset, capping the apiserver at 1 CPU / 512Mi -- a
quarter of the memory the chart itself ships as the default (c1.medium,
2 CPU / 2Gi).

512Mi does not hold a two-node tenant cluster running the full addon set.
Once the workers join, cilium, coredns, metrics-server, csi, ingress-nginx
and VPA all establish watches at roughly the same moment, and the apiserver
crosses the limit: one replica is killed for failing its liveness probe as
reclaim stalls it, the other is OOMKilled outright. Both replicas restart
within about two minutes of each other, so any tenant HelmRelease that is
mid-install and waiting on a DaemonSet rollout observes 'InProgress' for
its entire timeout and fails, then re-enters a fresh install on remediation.

Which release loses is a matter of timing rather than of the release, which
is why the failure moved between the csi, ingress-nginx and cilium releases
and looked like an unrelated dependency problem each time.

Use the chart default so the test exercises a control plane sized the way a
real one is, instead of one held at a quarter of the shipped default.

Aleksei Sviridkin 3a82ed43bc test(etcd): stop losing the metrics probe's output to the attach race
The metrics contract runs a one-shot curl Pod and reads a `code=<status>`
marker back through `kubectl run --attach`. Attach connects only after the
Pod reaches Running, so a container that exits before the connection is up
writes its stdout into the void: the step then sees only kubectl's own
"If you don't see a command prompt, try pressing enter." and reports the
metrics endpoint as broken. curl against a Pod IP finishes in milliseconds,
so losing that race is routine, and `--rm` compounded it by deleting the Pod
the instant it exited, taking the log that still held the real output.

The result was a false negative on a healthy cluster, non-deterministic in
the way that reads as a flake because whether attach wins depends on Pod
startup timing rather than on anything under test.

Drop `--rm`, keep the Pod until its result is in hand, and re-read the log
when the attach stream carried no marker. The recovery cannot mask a real
failure: the marker encodes the outcome, so a recovered `code=503` stays a
failure, and a stream that already carried a marker is never second-guessed.
The pre-run delete stays blocking so the re-read cannot find a previous
incarnation's marker, and the post-run delete is guarded so a transient API
error cannot abort the step with the result in hand but unreported.

Pin `--pod-running-timeout` at 90s rather than leaning on kubectl's 1m
default. curlimages/curl is not otherwise used on these nodes, so the probe
pays a cold pull, and a pull that outruns the budget produces the same
markerless output this change exists to explain.

The resolver is split into a sourced helper so the recovery is unit-tested
without a cluster; the kubectl orchestration around it stays covered by the
e2e run. The image-cache probe carries the same recovery inline for the same
race.

  `. sourced`, so there is no runtime interpreter to infer from a shebang.
- Add a `# TODO(chainsaw>0.2.15)` marker at the postgres Service asserts
  explaining the `(ports[0].port)`/`(ports[*].port)` projection is a v0.2.15
  number-literal-filter workaround (and that `ports[0]` checks only the first
  port), so it gets reverted on a chainsaw bump; cross-references the same
  workaround in kafka/mariadb/harbor and the e2e-testing.md gotchas section.

Myasnikov DaniilandClaude Opus 4.8 ff0d0d77a7 test(e2e): make the talos image cache reachable by tenant workers (#3254)
The in-sandbox Talos image mirror (#3244) is unreachable by the tenant
workers it serves, so the kubernetes-* e2e tests fail deterministically at
the 12m node-join wait instead of relieving the public-factory flake (#3231).

Root cause (from #3254 by @lexfrei, verified against the failing run's
crust-gather snapshot): tenant namespaces run a default-deny Cilium egress
(allow-internal/external-communication + the <tenant>-egress CCNP) that
permits the world entity and the tenant tree but NOT an arbitrary kube-system
Service, so a worker's CDI importer resolves talos-image-cache.kube-system.svc
yet its TCP connect to the ClusterIP is silently dropped and no disk imports.
#3244's gate never caught this because it probed the server over localhost
inside the serve pod, which passes regardless of cross-pod reachability.

Port of #3254 to the Chainsaw layout (hack/e2e-chainsaw/_lib/):
- ship a tightly-scoped CiliumClusterwideNetworkPolicy (importer pods in
  tenant-test -> mirror pod in kube-system), applied at point-of-use once
  Cilium CRDs exist; excluded from the pre-Cilium install apply via yq.
- replace the readiness probe with a throwaway pod in tenant-test labelled
  cdi.kubevirt.io=importer that curls the ClusterIP with a range request and
  must get 206 - the exact egress path a real importer faces; tenants use the
  mirror only when that end-to-end check passes, else fall back to the public
  factory, so it can only help, never make CI worse.
- unit test pinning the manifest split, probe/policy label agreement, the
  strict 206 gate, and the --overrides JSON builder.

Also adds (a2) DataVolume import-stage diagnostics to the node-join failure
block in run-kubernetes.sh (importer logs + a ClusterIP re-probe via
talos_image_cache_diagnose) so the import-stage failure mode is legible.

Myasnikov DaniilandClaude Fable 5 1f84d2d49e Merge origin/main into feat/e2e-chainsaw-example (post-#3244)
Fold the in-sandbox Talos image cache work into the Chainsaw layout:
the new shared helper relocates to hack/e2e-chainsaw/_lib/
talos-image-cache.sh and run-kubernetes.sh sources it from there (the
ouroboros DNS-check no-retry rework merges clean). The OIDC bats are
resolved as deleted again; their Chainsaw fixtures deliberately skip
the talos.imageFactoryURL injection — the helper only emits it when
the cache is up, and the zero-worker render-side tests instantiate no
DataVolume imports for it to redirect.

Myasnikov DaniilandClaude Fable 5 ece64ee0a9 test(etcd): re-port the Chainsaw suite to the v1alpha2 operator contracts
The suite was ported from the pre-#2859 etcd.bats and asserted
etcd.aenix.io/v1alpha1 objects that no longer exist on main — every
Test hard-failed at the first assert on an unknown GVK.

- drop the etcd-empty-backup and etcd-backup-schedule scenarios with
  their fixtures: the chart no longer renders EtcdBackupSchedule or
  etcd-s3-creds (backups moved to the generic backups API), and
  legacy-values tolerance is pinned by helm-unittest, not e2e
- rewrite the remaining scenario into etcd-1-contracts, mirroring
  main's contracts test: gate on status.readyMembers=3 (Available=True
  flips at seed-member discovery and races replica-count contracts),
  assert the operator-owned member Pod shape (strict selector,
  container name, named metrics port), WorkloadMonitor
  operational/availableReplicas, and script the three contracts that
  need imperative probes: the /scale subresource, the plaintext-HTTP
  metrics probe against the Pod IP, and the on-demand defrag Job
- add etcd-2-backup-roundtrip driving examples/backups/etcd/run-all.sh,
  gated on ETCD_E2E_S3_ROUNDTRIP=1 exactly like main (kind CI has no
  publicly-trusted S3 endpoint the snapshot agent could verify)
- upgrade catch blocks to the v1alpha2 GVKs plus EtcdMember/
  EtcdSnapshot/BackupJob describes and the snapshot-Job Pod logs
- strengthen _lib/etcd-cleanup.sh with main's etcd_drain deltas: probe
  the Etcd CR itself (it can linger Terminating and block the next
  singleton apply) and use the err-sentinel pattern so a transient API
  error is never misread as "deleted"; add etcd_backup_cleanup wrapping
  examples/backups/etcd/cleanup.sh for the round-trip's teardown

- keep main's run-kubernetes.sh helpers (kubectl_wait_retry, tenant
  drain, LINSTOR pool-free wait, SC-fallback probe) under the branch's
  _lib/ rename with the Chainsaw finally/snapshot deltas re-applied
- resolve modify/delete on 10 drifted hack/e2e-apps/*.bats as deleted;
  their post-branch assertion drift is re-ported into the Chainsaw
  suites in follow-up commits
- drop the 4 new main-side bats (kubernetes-oidc-*, securitygroup,

Myasnikov DaniilandClaude Opus 4.8 2141d8a5da test(e2e): delete etcd data PVCs in the drain to fix quorum wedge
The etcd suite still failed every run after the clean-after-each rework:
etcd-empty-backup (first to run) passed, but etcd-basic and etcd-backup-schedule
wedged at EtcdCluster WaitingForFirstQuorum until the chart's helm --wait timed
out (InstallFailed).

Root cause, from the failed run's crust-gather snapshot: the StatefulSet's
data-etcd-{0,1,2} PVCs are retained on uninstall and the drain never reclaimed
them, so each later scenario rebound the first scenario's volumes (identical PV
UIDs and a single creationTimestamp across all three scenarios) and booted the
previous etcd's data dir and member identity — never forming a fresh first
quorum. The pods were individually Ready (StatefulSet readyReplicas: 3) with all
certs valid, which is why it looked like an operator/network issue rather than
stale storage.

Delete the data PVCs (app.kubernetes.io/managed-by=etcd-operator) in
etcd_cleanup and wait for them to clear alongside the HR and DataStore, so each
scenario starts from empty storage.

Myasnikov DaniilandClaude Opus 4.8 a820afc98c test(e2e): tear down each etcd scenario in a guaranteed finally
The three etcd scenarios share the singleton 'etcd' release and relied on the
next scenario's ensure-clean to drain the previous one. Chainsaw runs Tests in
name order (not file order), and v0.2.15 has no test-level finally, so the
last-run scenario leaked its etcd plus the wedged Kamaji DataStore into every
later suite on full/release runs (lexfrei review B3).

Make each scenario self-contained instead: a single run step pre-cleans any
leftover etcd, installs and asserts, then drains in a finally that always runs
(the step is always reached, so teardown fires on success and failure alike).
Extract the shared drain to _lib/etcd-cleanup.sh, removing the ~25-line block
that was copied across all three scenarios.

Myasnikov DaniilandClaude Opus 4.8 03a9c51ea2 test(e2e): reclaim the tenant Kubernetes cluster in a Chainsaw finally on failure
run_kubernetes_test applies the tenant Kubernetes CR imperatively (kubectl), so
Chainsaw's auto-cleanup — which only tracks resources it apply/create-d — never
reclaims it. On success the script's tail deleted it, but on failure nothing did:
cozy_cleanup() used to be invoked by hack/cozytest.sh's trap, and the Chainsaw
harness has no equivalent caller, so a failed kubernetes-latest/previous run
leaked the tenant cluster (tens of GiB of worker PVCs) into the shared
tenant-test namespace and starved later suites.

Add a `finally` block to both kubernetes suites that runs cozy_cleanup. `finally`
always executes, after the `catch` phase, so the ordering matches the BATS
harness: pass -> cleanup; fail -> crust-gather (tenant trap + host catch) ->
cleanup. cozy_cleanup stays best-effort (|| true) so a slow tenant teardown never
flips a passing test red.

Myasnikov DaniilandClaude Opus 4.8 2940093102 test(e2e): capture per-failed-test crust-gather snapshots in Chainsaw harness
The Chainsaw app suite runs via `chainsaw test` directly, bypassing
hack/cozytest.sh — whose EXIT trap captures a crust-gather host snapshot
per failed BATS test. As a result a failing Chainsaw run uploaded a
cozyreport.tgz with zero per-test cluster snapshots, the richest diagnostic
for failures like the gateway/etcd/bucket/openbao ones on this branch.

Add the Chainsaw analog: a global spec.error.catch in .chainsaw.yaml that
collects a bounded host snapshot into _out/cozyreport/snapshots/<test>/host
on any failure (same --exclude-kind Secret flags and timeout -k 30 300 as
cozytest.sh), keyed by the $test.metadata.name binding with a mkdir-guard so
repeat catch invocations don't re-collect. Wire COZY_SNAPSHOT_NAME into the
kubernetes-latest/previous suites so the existing tenant snapshot from
run-kubernetes.sh co-locates under the same snapshots/<test>/ dir. cozyreport.sh
already folds snapshots/ into the uploaded artifact.

The e2e-testing guide and the sandbox Dockerfile comment are updated to record
the convention.

Myasnikov DaniilandClaude Opus 4.8 e22d84f2c8 test(e2e): migrate app suite from BATS to Chainsaw and wire into CI
Replaces the per-app BATS E2E suite (hack/e2e-apps/*.bats) with declarative
Kyverno Chainsaw tests under hack/e2e-chainsaw/, extending this branch's pilot
(postgres + bucket) to all 18 app suites.

- Declarative ports assert on status/conditions and concrete fields; the
  repeated "timeout ... until kubectl get" + "kubectl wait" boilerplate
  collapses into a single polling assert with structured failure diffs and
  automatic events/describe/podLogs capture on failure.
- Inherently imperative suites keep their logic in script steps: openbao
  init/unseal, kuberture split-horizon probes, vminstance, the gateway
  admission/impersonation cases, and kubernetes-latest/previous, which wrap
  the relocated hack/e2e-chainsaw/_lib/run-kubernetes.sh verbatim.
- Gateway tests derive the tenant apex from the namespace host label at
  runtime, so they are host-independent.

CI: the e2e job now runs "chainsaw test hack/e2e-chainsaw/" via a new
test-chainsaw target and uploads the JUnit chainsaw-report.xml; the chainsaw
binary is added to the e2e-sandbox image. install-cozystack and test-openapi
stay BATS. The per-app 3-retry loop is dropped, since assertion polling
replaces the fixed-timeout flakiness it papered over.

Verified against a dev cluster (DB/app, storage and VM suites pass). Service
port assertions use the ports[*].port projection form because Chainsaw
v0.2.15 mis-evaluates JMESPath number-literal port filters.
