Summary

Adds aicr upgrade-check --from cluster, which takes the from side of the comparison from what the deployer actually installed, and --scan-cluster, an advisory scan for live objects an upgrade could destroy (ADR-021 Decisions 3 and 5). pkg/inventory reads the cluster; pkg/upgrade and pkg/client/v1 render and wire it.

Motivation / Context

aicr upgrade-check (#2760) compares two artifacts, which assumes the old bundle in git is what is deployed. Reading the cluster answers which version is installed, including where that has drifted from git. The scan exists so a CRD removal cannot silently take an operator's own custom resources with it.

Fixes: #2531
Related: #2530, #2760, #2995, #3030, #3031

Type of Change

  • Bug fix (non-breaking change that fixes an issue)
  • New feature (non-breaking change that adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update
  • Refactoring (no functional changes)
  • Build/CI/tooling

Component(s) Affected

  • CLI (cmd/aicr, pkg/cli)
  • API server (cmd/aicrd, pkg/server)
  • Recipe engine / data (pkg/recipe)
  • Bundlers (pkg/bundler, pkg/component/*)
  • Collectors / snapshotter (pkg/collector, pkg/snapshotter)
  • Validator (pkg/validator)
  • Core libraries (pkg/errors, pkg/k8s)
  • Docs/examples (docs/, examples/)
  • Other: new pkg/inventory, pkg/upgrade, pkg/client/v1, KWOK read-back lanes

Implementation Notes

Read from Kubernetes, not through Helm. The Helm SDK was declined in #2530 (38 permanently scanned modules), and the helm binary costs N+1 subprocesses and a second authentication path. Helm's release records are read from their Secret and ConfigMap storage directly, one paged List per driver, decoding only each release's newest revision. Argo CD writes no Helm release, so argocd and argocd-helm read Application objects. Only the reader the named deployer writes runs.

A version counts only once it is established. A Helm release answers only from a newest revision that reached deployed; Helm writes an upgrade's target before applying it. An Argo CD Application answers from status only: the pin in its Synced comparison, else its newest completed sync in status.history, never spec's targetRevision (and never the recorded revision, which for an OCI chart is a digest). Otherwise the component reads unversioned.

A component the read can place is never lost. Dropping one reads as newly installed, which drops its transition and steps and exits zero. So:

  • Candidate namespaces include the --to recipe's, and under flux the release's own target namespace.
  • A record the read places but cannot version (undecodable, held by both Helm storage drivers, or a prefixed Application outside every candidate namespace) keeps the component as installed and unversioned.
  • Argo CD Applications deploying to another cluster are excluded and counted as remote; a named destination resolves through Argo's cluster Secrets or is refused.
  • AICR-stamped releases that match no component fail a strict run.

Strictness follows confidence. Every record is matched loosely to be found, but only a name the deployer itself writes fails the run when it cannot be read; a looser match is counted and kept as unproven. The storage labels remain the one source of a release's identity: the payload's namespace is read only as a hint for flux attribution.

The at-risk scan is advisory. It lists the kinds the crossed transition records name and reports objects carrying no Helm or Argo CD ownership marker. Findings never change the exit code. A kind counts as absent only once discovery has enumerated its API group.

KWOK read-back on every deployer. Each Tier 1 lane deploys a bundle, reads it back with --from cluster, and diffs the result against --from <bundle>. The only excusable difference is an allowlisted component (kai-scheduler) whose Argo CD sync KWOK cannot finish.

Testing

go test -race ./pkg/inventory/... ./pkg/upgrade/... ./pkg/client/v1/... ./pkg/cli/... \
  ./pkg/header/... ./pkg/defaults/... ./pkg/k8s/client/... ./pkg/chainsaw/... ./pkg/recipe/ ./pkg/bundler/...
make lint
bash kwok/scripts/lib/upgrade-readback_test.sh
bash kwok/scripts/lib/deployer-map_test.sh

All pass. make qualify passes locally apart from tooling gaps on this machine that reproduce on clean main (an older local helm for pkg/oci, no GNU timeout for tests/releasepolicy, no oasdiff). KWOK: all 24 Tier 1 read-back lanes (every deployer) passed on 59d2371. The Tier 2 Slurm lanes failed earlier on a main bug fixed by #2994 and have not run on this branch since; CI on the current head is in progress.

Risk Assessment

  • Low — Isolated change, well-tested, easy to revert
  • Medium — Touches multiple components or has broader impact
  • High — Breaking change, affects critical paths, or complex rollout

Rollout notes: Additive. An artifact comparison is unchanged and still contacts no cluster. --from cluster and --scan-cluster are opt-in; their permissions are documented in docs/user/cli-reference.md.

Checklist

  • Tests pass locally (make test with -race)
  • Linter passes (make lint)
  • I did not skip/disable tests to make CI green
  • I added/updated tests for new functionality
  • I updated docs if user-facing behavior changed
  • Changes follow existing patterns in the codebase
  • Commits are cryptographically signed (git commit -S) — GPG signing info

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Pass the deployer explicitly in this artifact-to-artifact example.

Bundles expose recipe.yaml, not the deployer that built them, so upgrade-check cannot infer argocd from --to. This comparison matches a transition with a manual step, and UpgradeCheck rejects the request before --scan-cluster runs when --deployer is empty. Remove the inference claim and update the command:

$ aicr upgrade-check --from ./bundles-v0.16.0 --to ./bundles-v0.17.0 --scan-cluster --deployer argocd

they no longer claim cluster state is never read and clearly explain the

scanAtRisk into a shared validateKinds helper. Call validateKinds in ScanAtRisk
immediately after the empty-Kinds check and before constructing Kubernetes
clients, while retaining the validation call in scanAtRisk so the internal entry
point remains self-checking and returns ErrCodeInvalidRequest for trimmed-empty

A cluster read that matches no release reports rather than failing, so
every row beneath then renders as added. The Source banner is what
distinguishes an empty cluster from a kubeconfig pointed at the wrong
context, which is why it renders above the rows rather than as a footnote.

Counts stay per-reader and separately typed: the Helm side counts storage
records, the Argo side counts Applications, and summing them would put
incomparable quantities in one number.

AffectedResources has been in the record schema since #2760 with no
consumer. This is the first: for the transitions a match actually
crossed, list objects of the named kinds that carry neither Helm nor
Argo CD ownership and report them.

Ownership is a positive test, so an object with no recognized marker is
at risk by default. That over-warns when a marker is missed, which is
the right direction: the failure guarded against is a user's own CRs
being cascade-deleted by a CRD removal, and the scan is advisory either
way. It never touches the exit code.

The section renders even when nothing was scanned, because an absent
warning reads as an all-clear.

The RESTMapper constructor moves to pkg/k8s/client for the same reason
the dynamic client did: pkg/inventory must not reach pkg/chainsaw.

ErrCodeCanceled exists because a timeout is an environmental fault
worth retrying and a cancellation is an instruction to stop: IsTransient
reports false for it, ahead of the ErrCodeTimeout branch. Mapping
context.Canceled to ErrCodeTimeout therefore reported a Ctrl-C as
transient and retryable, and lost ExitCanceled. pkg/serializer and
pkg/evidence already enforce the split.

Five sites, not the two a reviewer listed: ctxErr, argoListError,
listError, and scanKind's List path, which wrapped every failure as
ErrCodeUnavailable so an abort read as an unreachable apiserver.
resolveKind takes no context and cannot produce one.

Reverting argoListError passed at first: every Argo cancellation test
reached ctxErr instead, and its only List-error coverage seeded
DeadlineExceeded, which both branches answer alike. Covered now.

Also: report distinct namespaces when an install is ambiguous, since
two Argo Applications in one namespace rendered as a namespace conflict
that did not exist; and assert Records over the ConfigMap driver.

Three claims the implementation disproved.

The SDK: #2530 was closed not-planned. Linking helm.sh/helm/v4 adds 38
permanently scanned modules that survive linking because the storage
backend blank-imports a Postgres driver for its init. Records are read
from their Kubernetes storage instead, which the decision's dichotomy
of N+1 subprocesses or the SDK omitted entirely.

The name mapping: a release name equals its ComponentRef name for helm
and helmfile only. Flux composes <targetNamespace>-<name>; Argo CD
prepends a user-settable prefix that need not end in a hyphen. Left
unhandled this yields no error and no warning, just a clean empty
inventory in which every component reports as newly added. Acceptance
Criterion 4 would have certified it, so it now requires per-deployer
coverage.

Argo CD writes no release record at all, which the document never said.

Also: the at-risk ownership test needs the Argo marker, the version
rule needs the registry guard on its chart-version branch, and the
status block claimed no matcher or CLI exists when #2760 shipped both
for artifact comparison.

Three tests that passed without proving anything.

The paging case asserted a total that held whether or not scanKind
paged, because dynamicfake ignores ListOptions.Limit entirely. Renamed
to say what it does, and a two-page reactor now pins that findings from
the second page reach the result, failing on identity rather than count.

atRiskNothingDeclared and the unattributed-kind render are both states
the design names deliberately, and nothing rendered either. Coverage
was the only witness that they were missing.

The two cluster goldens rendered 'from cluster' above 'not scanned: no
cluster access requested'. The contradiction is in the fixtures, not in
NewReport: teaching pkg/upgrade that Source implies cluster semantics
is the coupling its package doc refuses.

Signed-off-by: Brian Lockwood <lockwobr@gmail.com>
From now accepts a "cluster" sentinel beside a path and a cm:// URI,
and ScanAtRisk requests the advisory scan alongside either source.
Decision 5 calls these independent axes: the scan needs a cluster
whatever the from table came from, so comparing two bundles while
scanning a live cluster is a legitimate combination.

Match is untouched. It already took two component -> version maps, so
a cluster read is a new way to build one and nothing else.

To is required for a cluster read, with its own message: a cluster
carries no criteria to re-resolve, which is a different fact from an
artifact that happens to have none. The deployer is required too,
because attribution differs per deployer and without it nothing maps.

A scan failure reports as unscanned and never fails the run. An
advisory feature taking down the comparison it annotates is the wrong
trade, and a failed scan rendering as an all-clear is worse than no
scan at all.

Two ways an unchanged component reported as changed, both found by
reading what the e2e read-back would compare before running it.

The argocd deployer normalizes a chart pin onto the Application
(NormalizeVersion trims a leading v), so a cluster sitting at v26.7.0
reads back 26.7.0. Match compared as written, so that produced a row,
which matchVersions then parsed to the same semver, crossed nothing,
and reported unknown: every Argo CD user told three components needed
attention on a cluster already at target. The equality decision now
ignores a leading v on both sides. It still compares as written
otherwise, so two pins differing in build metadata still report, and
the row still displays what each side actually said.

stampFor stamps AICR's own version when a component pins neither a
version nor a tag, so a manifest-only component read back 0.0.0-dev
while the artifact side read nothing. The fallback is detectable
because it writes that value to component-version and generated-by
alike, but equality alone would also fire on a component genuinely
pinned to the AICR version, which the registry already has in range.
Gating on the component having no upstream chart makes the two
mutually exclusive by construction.

The stamp shipped in v0.21.0, so installed clusters carry it and the
read side has to handle it whatever the writer does later.

The flags that make the cluster read reachable. From takes a cluster
sentinel beside a path and a cm:// URI; --scan-cluster requests the
advisory scan, which Decision 5 makes an independent axis, so scanning
a live cluster while comparing two bundles is legitimate.

ScanAtRisk is a *bool rather than a bool. The scan is implied by a
cluster read, and a plain bool cannot express an explicit no against an
implication: --scan-cluster=false was silently overridden. nil means
not set and takes the implication, and an explicit false wins, because
a flag somebody typed should do what it says. The field is v1 SDK
surface behind an api-diff gate, so the shape had to be right before
it tagged rather than after.

A declined scan reports its own reason. Offline says no cluster access
was requested, which misattributes a refusal to an absence.

After a bundle deploys, upgrade-check --from cluster must produce the
same component table as --from <that bundle>. The artifact path is the
oracle, so there is no golden to maintain and any divergence is by
construction a bug in the cluster read. ADR-021 acceptance criterion 4.

It runs on the existing deployer matrix, which is what makes it worth
having: the per-deployer name mapping was inferred from reading
templates, and flux composing <targetNamespace>-<name> had never been
observed against a running helm-controller.

Excluded from the comparison: the from field, which is a sentinel on
one side and a path on the other; the source block, which only a
cluster read has; and the at-risk section, whose counts depend on
whatever else is on the cluster. Three assertions stop two identically
broken reads diffing clean, since both would say everything is added.

The matrix-to-deployer mapping was three hardcoded literals and an
inline branch; it is now one table with a drift test against the
workflow array and against the real DeployerType values.

Where the cluster read and identity pinning meet. A relocation holds
its version, so no record's floor sits between the endpoints and the
at-risk scan draws nothing from it: listing those kinds anyway would
name objects a namespace move does not touch, under a heading that
says a CRD removal may take them with it.

The test asserts both directions. The second is the one that matters:
a hop that both moves namespace and changes version must still
contribute the crossings its version half made, or the scan goes
quiet on exactly the rows that need it and nothing else notices.

The package doc gained the Source and at-risk paragraphs it never
had, in render order.

The read-back writes its evidence only on failure, so a green leg
printed PASSED and nothing else. That mattered more than it sounds:
the first confirmation that helm-controller composes
<targetNamespace>-<name> came from an unrelated cleanup step that
happens to print release names it read from helm list -A. Proof by
byproduct survives exactly until somebody reorders that cleanup.

The source accounting is what the read-back actually establishes:
how many records were read, how many matched, and stampedUnmatched,
which is the broken-mapping detector. Helm and Argo stay on separate
lines because they count different units, and Argo says the stamp
check does not apply rather than printing a zero.

Logging only. It cannot change a leg's outcome: a missing report or
an absent source block prints nothing and returns 0, and the call
site avoids the && form that would let set -e kill a green leg on a
blank line.

This makes the evidence visible for the log retention window, not
durable. Uploading the artifacts unconditionally would do that, at 18
legs per PR of storage for something read approximately never.

The pages said no cluster state is inspected, that --kubeconfig only
mattered for a ConfigMap URI, and that a cluster comparison was still
tracked in #2531. All three shipped false the moment --from cluster
landed.

Both flags are now documented with what the read actually answers: a
version question, from what Helm and Argo each recorded they last
applied. A resource somebody edited by hand leaves the record
untouched and reading it will not say so.

The limits are stated rather than left to be discovered: a cluster
read reports no relocation, because attribution uses the registry's
namespace and three of five deployers cannot see a component that
moved; the scan sees ownership markers, not use; and an empty at-risk
section is not an all-clear.

Signed-off-by: Brian Lockwood <lockwobr@gmail.com>
The Description opened "No cluster state is read" sixty lines above
the --scan-cluster declaration, and --from, --to and --deployer all
omitted the sentinel pkg/client/v1 defines and the command passes
straight through. Two agents found it independently, from opposite
directions; the docs were already correct and only the help lagged.

Rewritten rather than appended to, and the four usage strings now
interpolate aicr.FromCluster instead of spelling it, so help and
constant cannot drift. A test pins that the sentinel is named and the
old sentence is gone.

Separately, ScanAtRisk built a kubeconfig, a dynamic client and a REST
mapper before validating its own kinds, so a caller's malformed input
surfaced as an infrastructure failure. Validation is hoisted above
client construction and extracted so scanAtRisk stays self-checking.

The guard is the message, not the code: GetKubeClientWithConfig wraps
a missing kubeconfig as ErrCodeInvalidRequest too, so asserting the
code alone passes against the bug. Hoisting also makes the path
reachable without a cluster, taking ScanAtRisk from 16.7% to 28.6%.

Signed-off-by: Brian Lockwood <lockwobr@gmail.com>
upgradeCheckScan funnelled every scan error into an advisory Reason
and UpgradeCheck returned nil straight after, so a caller who pressed
Ctrl-C during the scan got a successful report. That also defeated a
fix made one layer down: pkg/inventory's ctxErr separates
ErrCodeCanceled from ErrCodeTimeout so a cancel is not classified
retryable, and the facade flattened it into a string.

The test is the caller's own ctx.Err(), not the sentinel and not the
code. The scan runs under its own 60s budget, deliberately shorter
than the run's 90s so a slow cluster cannot hold up a comparison that
already finished. When that inner budget expires with time left on
the caller's clock, abortError emits ErrCodeTimeout over
DeadlineExceeded, which is byte-identical to what the caller's own
expired deadline emits: from one level down they are the same event.
Testing either would have turned the case the 60s budget exists for
into a hard failure.

Decision 3 is untouched. It keeps scan findings out of the exit code,
and an abort is not a finding. RBAC denials and unreachable
apiservers stay advisory.

The tests assert IsTransient rather than the code alone, because a
bare context.Canceled carries the right sentinel and still reports
transient, and they pin that the scan actually ran so an error raised
earlier cannot satisfy a bare non-nil check.

The Argo reader took a chart's version from spec.source(s).targetRevision,
which is the pin Argo has been asked to reach. A pin changed while its sync
is pending or has failed leaves the old chart running, so the read reported
an upgrade not yet made as made and hid that transition's manual and blocked
steps.

The version now comes from status only: a Synced status.sync answers with
the revision it last compared, else the newest status.history entry (a
completed sync), else nothing, which reads as unversioned. The chart is
matched by name in the status sources, and revisions are paired with
sources index for index.

The at-risk scan treated every RESTMapper no-match as the kind not being
installed. client-go discards a partial discovery failure whenever other
groups answered and returns a bare no-match, so a kind in an unreachable
group was skipped and the scan reported clean over the objects it exists
to warn about.

A no-match now counts as absence only when it wraps no group failure and
discovery enumerated the kind's own API group, probed through the cache the
mapper resolves with. Otherwise the scan fails and its report says why. The
two checks move from pkg/chainsaw to pkg/k8s/client so both callers share
one implementation.

…digest

For an OCI chart, Argo records the manifest digest as the revision in both
status.sync and status.history, so every OCI-sourced component read back
as sha256:... and compared as unversioned on every Argo KWOK lane.

The version is now the targetRevision in status's own copy of the chart's
source: comparedTo when Synced, the history entry's source otherwise. That
copy is what was compared or deployed, not the spec's pin, so a pending
pin change still reads as not yet made. Revisions no longer need pairing
with sources, and that check is gone with them.

The cluster read now takes an Argo CD chart version only from a sync that
established one. On KWOK some never do: kai-scheduler's sync operation
waits on a namespace health state the simulator does not produce, so it
stays OutOfSync with no history and reads as unversioned, and the
read-back failed on it.

The Argo lanes list Applications before the cluster read. A component may
read as unversioned with no `from` only when its Application is neither
Synced nor has a completed sync; any other difference still fails, and
each excused row is logged and kept as excused-unsettled.txt.

The reader took the newest revision's chart version whatever its status.
Helm writes an upgrade's target revision before applying anything, so a
pending upgrade, or one whose pre-upgrade hook failed, reported the target
as installed while the old release still ran. Against a --to naming that
target, the comparison dropped the real transition and its steps.

Only a newest revision that reached deployed now establishes a version.
Any other status keeps the component installed, so it never reads as
added, and reads as unversioned: the read cannot prove whether a failed
upgrade changed resources, so it does not pick the target or the prior
revision.

Signed-off-by: Brian Lockwood <lockwobr@gmail.com>
The cluster-read docs said an Argo CD Application contributes what it is
configured to deploy, which the reader no longer does, and promised the
report names the kubeconfig context, which nothing populates yet.

Both pages now say a version counts only once established (a deployed
Helm revision, a synced Application revision), that pending or failed
upgrades read as unversioned, and that the context line reads "-" and
should be checked with kubectl.

Signed-off-by: Brian Lockwood <lockwobr@gmail.com>
Addresses the third review round on the cluster read. Each change keeps a
component the read can place from reading as newly installed, which drops
its transition and steps and exits zero.

- Argo CD Applications deploying to another cluster are excluded and
  counted as remote. A destination server is local only as Argo's
  in-cluster address; a named destination resolves through Argo's cluster
  Secrets, and one that cannot be resolved is refused.
- Candidate namespaces include the --to recipe's, and under flux the
  release's own target namespace, so a component an overlay, a mixin or
  --inherit-from moved is still found.
- A record the read places but cannot version (undecodable, held by both
  Helm storage drivers, or a prefixed Application outside every candidate
  namespace) keeps the component as installed and unversioned.
- The confident tier follows the deployer, so flux's own release names
  fail closed and a bare name cannot fail a flux read.
- Only the reader the deployer writes runs, so a 403 on Argo CD cannot
  fail a Helm-only cluster. Its source line reads "not read".
- AICR-stamped records that match no component fail a strict run.
- A cluster run gets a budget that covers its reads and scan; --to
  cluster is rejected; the KWOK unsettled-Application excuse is limited
  to an allowlist.

Docs: readers per deployer, namespace candidates, permissions, cluster-read
exit codes, the vendored-chart and ownership-marker limits, and stale
citations and wording in the ADR, package docs and CLAUDE.md.
