🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winMake registration cleanup a required part of disconnect.
REST deletes the
PackageSourcebefore it looks up the registrationPackage. A lookup error skips cleanup and still returns success. A non-NotFounddelete error is only logged and also returns success. A later retry sees noPackageSourceand entersdeleteOrphanTapSource, which deletes only the labeledOCIRepository; it does not retry thePackage.
cozypkg untapalso ignores everyPackagelookup error, not onlyNotFound. It can delete thePackageSourceand return success while leaving the registrationPackageand its catalog entries. A lateruntapfails while fetching the now-missingPackageSource, so it cannot retry Package cleanup. Package deletion errors themselves are already returned before the CLI deletes thePackageSource.

NOT LGTM — the RBAC grant is fine, but connecting a tap now installs charts, and the confirmation that guarded that on cozypkg add does not exist on the new path.
IvanHunters this is the first review here, so I started with the RBAC change and worked outward from it.
The RBAC grant
templates/rbac.yaml:35-37 adds packages to a cluster-scoped rule that already carried packagesources, verb delete, no resourceNames. It cannot be narrower than that: authorization has no label or field selector, and the object name is a tap name known only at runtime, so resourceNames is not usable. No tenant role in cozystack-basics grants create or delete on taps at all, up to and including cozy:tenant:super-admin:base, which wildcards only kubevirt.io/virtualmachines and apps.cozystack.io/*, so reaching the code path needs a grant from outside the tenant set. The name from the request path is filtered twice before it reaches a Package: rest.go:316 refuses a PackageSource without the tap label, rest.go:334 refuses a Package without it, and a platform-shipped Package carries neither. I would not change the grant.
Blockers
The privileged-install confirmation is gone on the connect path
add.go:469-477 refuses to create a Package whose variant has a component with install.privileged: true unless the operator answers y to "These run with elevated cluster access. Install anyway? [y/N]" or passes --allow-privileged. ensureRegistrationPackage creates the same kind of Package with no such check. The Package reconciler then creates a HelmRelease for every install-marked component of that variant (package_reconciler.go:208), and reconcileNamespaces puts pod-security.kubernetes.io/enforce: privileged on component.Install.Namespace when any component there is privileged (package_reconciler.go:824), applied with client.Apply plus ForceOwnership (:901), so an existing namespace picks the label up too. Both the component list and the namespace name come out of the tapped artifact.
The dashboard route has even less in front of it. REST.Create writes only the OCIRepository, and the materializer runs collision.PackageSourceName and nothing else. ValidateRepo only ever runs in the CLI (tap.go:251).
The PR body says the app components carry no install block, so registration deploys no workload. That holds for the repository you tested and nothing enforces it. Either refuse to auto-register a variant that carries privileged install components and surface that through the MaterializeErrorAnnotation and MaterializeFailed machinery already there for collisions, or set Spec.Components[<name>].Enabled = false for those components on the Package you create.
cozypkg tap --help still promises the old behaviour
tap.go:212 says "Nothing is installed until 'cozypkg add'." The PR rewrites the trailing print of that same RunE at line 330 and leaves the sentence above it. It is the documented contract of the command this PR changes.
The registration Package outlives its PackageSource
pruneMaterialized deletes PackageSources only, and deleteMaterialized is pruneMaterialized(ctx, name, nil). When a later artifact revision drops a package, or the OCIRepository is deleted directly, the PackageSource goes and the registration Package stays, with its HelmRelease (owner reference is the Package, package_reconciler.go:290) and the ApplicationDefinition that HelmRelease installed. The comment right above the prune call at :188 says a removed package leaves the catalog; after this change it does not. CodeRabbit raised this one and it is still open.
There is a second half to it. The leftover Package keeps the tap label and a tap-source annotation naming the old tap, and both new delete paths check the label alone (rest.go:334, tap.go:369). Tap A's source is removed, its Package survives, tap B later materializes a PackageSource under that name, and disconnecting tap B deletes the Package that tap A created. ensureRegistrationPackage writes SourceAnnotation at :241 and nothing reads it back on a Package. The two-part predicate you want is already written as collision.Owns.
Two changed behaviours have no test
I deleted the IsAlreadyExists branch from add.go and go test ./cmd/cozypkg/... stayed green. I deleted the Package removal from untapCmd and it stayed green as well. tap_test.go has five tests and none of them reach untap. So the idempotency claim in the second commit, and a new code path that deletes a cluster-scoped object, both rest on the manual run.
rest_write_options_test.go:112 asserts dry-run propagation per backing resource and the new Package delete is missing from it, though rest.go:335 does pass it through. That one is a line.
The rest of the ladder came out clean, which is why those two stand out rather than reading as a blanket complaint. Widening the RBAC rule's resources or its verbs reddens the chart assert, appending a rule reddens the count assert, inverting the default-variant comparison reddens TestDefaultVariantName, flipping the tap label value reddens TestReconcileRegistersApps, and inverting the ownership check in rest.go reddens both TestDeleteRemovesRegistrationPackage and TestDeleteKeepsForeignPackage.
The first commit lands red
b51b941f0 changes templates/rbac.yaml without tests/rbac_test.yaml, and 6032cd1c0 fixes the assert afterwards. I put the old test file back on top of the current template and the chart suite fails on "grants delete on cozystack.io packagesources for tap disconnect". Squash and rebase are both off on this repository, so the first two commits land on main with that suite red. Fold the third into the first.
Non-blocking
ensureRegistrationPackage swallows IsAlreadyExists, so a Package that already exists under that name means the apps never register while the log still reports the PackageSource as materialized from the tap. The PackageSource name space gets a collision error, an Event and an annotation surfaced on the Tap. The Package name space gets silence.
rest.go:334 drops the Package Get error with no log line at all, and the Delete error goes to klog.V(2), off by default, while Delete still returns success. A disconnect that failed to de-register looks exactly like one that worked.
defaultVariantName falls back to Variants[0], so the order variants happen to be written in a third-party artifact decides what gets installed. An empty Spec.Variant already resolves to "default" in package_reconciler.go:148 and in resolvePrivilegedNamespaces, so leaving it empty would reuse that rule instead of adding a fourth one.
cozypkg del on a tap-registered app removes the Package and the materializer puts it back on the next artifact revision, so the de-registration quietly returns.
The PR body is used as the merge commit message verbatim here. The generated summary at the bottom says tap and untap guidance was updated; only untap's was. The two HTML comment markers go into git history along with it.
rbac_test.yaml:79 says "eighteen rules" while the asserts pin rules[19] and rules[20] and the template carries twenty. That predates this PR. Worth the word while the file is open.

This is where the privileged-install confirmation disappears. add.go:469-477 will not create a Package whose variant has a component with install.privileged: true unless the operator answers y or passes --allow-privileged; this path creates the same Package unconditionally, and both the component list and its install.namespace come from the tapped artifact. reconcileNamespaces then applies pod-security.kubernetes.io/enforce: privileged to that namespace (package_reconciler.go:824, patched with ForceOwnership at :901), so an existing namespace picks the label up too. Either refuse to auto-register a variant with privileged install components and report it through MaterializeErrorAnnotation the way a name collision already is, or disable those components on the Package via Spec.Components[<name>].Enabled = false.

IsAlreadyExists here is silent. A Package that already exists under this name (which happens after a prune leaves one behind, since pruneMaterialized removes PackageSources only) means the apps never register, while the log line right below still reports the PackageSource as materialized from the tap. The PackageSource name space gets collision.PackageSourceName with an Event and an annotation surfaced on the Tap; the Package name space gets nothing.

The label alone is not ownership. ensureRegistrationPackage writes tapconst.SourceAnnotation on the Package and nothing reads it back, so a Package left over from tap A (label still set, annotation naming tap A) is deleted when tap B, which later materialized a PackageSource under that name, is disconnected. collision.Owns is the two-part predicate already in the tree. Separately, the Get error is dropped with no log at all and the Delete error goes to klog.V(2), off by default, while Delete still returns success, so a disconnect that failed to de-register is indistinguishable from one that worked.

Same label-only ownership check as the API side, with the same consequence. Also nothing covers this branch: I removed the deletion and go test ./cmd/cozypkg/... stayed green, and tap_test.go has five tests, none of which reach untap. New code that deletes a cluster-scoped object should not land on a manual run alone.

Packageis cluster-scoped and uses its name as the identity. A conflicting object can be a tap-managed default registration, a stale registration, or a manual Package with a different variant or ownership metadata.

NOT LGTM — the privileged-install check from round one exists now, but it can still be bypassed, and the ten follow-up commits have not converged on a design that closes it.
IvanHunters I re-read the branch against my previous review. The first three commits are patch-identical after the rebase, and the rebase moved no file this PR touches, so everything below is about the ten new commits. Of the five round-one blockers, the help text, the orphaned registration Package with its label-only ownership check, and the two untested behaviours are closed. The first two commits still land red (B3), and the central one is closed only on the operator path (B1).
The design has not converged
Five of the new commits add a de-register on a privileged flip and then tighten the race it creates with the Package reconciler. They delete before apply, read uncached, add a UID and resourceVersion precondition, re-classify on conflict and fail closed when the conflict persists. They need all of that because the check sits outside the component that installs. The Package reconciler creates the HelmReleases and labels the namespace for whatever PackageSource it sees next to a Package, and it has no privileged check of its own. So every writer of that PackageSource, and every cache the reconciler reads through, is something the check has to outrun. Two of them still get past it (B1). The last four commits add a readiness override, patch it twice and revert it. What survives from them is the revision-annotation reset on re-connect. The registration-state annotation that the override read is again written and never read.
What remains is a Package in one of four states: absent, managed (tap label, matching source annotation, empty variant), handed over by cozypkg add, or left behind by another tap. Three writers move it between them: the materializer on a new revision, the CLI and the API. The conflict-aware delete is written three times (deregisterManaged, the loop in runUntap, the Delete in rest.go), and the API copy tolerates a conflict where the other two retry. The ownership predicate is written twice (B4).
Blockers
B1: A managed registration can still install a privileged component without confirmation
Re-tapping an auto-registered repository from the CLI writes the new PackageSource while the managed Package still stands. cozypkg tap <ref> --tag <new> applies the artifact's PackageSource itself (tap.go:334-345), and rewritePackageSourceForTap keeps its variants, which TestRewritePackageSourceForTap pins. The operator's pre-apply de-register runs only once source-controller reports the new revision (tapmaterializer_reconciler.go:122). The clearMaterializedRevision call after the apply loop does not change that order. The Package reconciler enqueues the same-named Package on any PackageSource event (package_reconciler.go:970-990). I ran its Reconcile against a managed registration Package and a PackageSource whose default variant has a privileged install component. The target namespace, which already existed, got pod-security.kubernetes.io/enforce: privileged, and a HelmRelease labelled cozystack.io/privileged: true was created. Whatever closes that window afterwards is the operator winning a race, the hazard 50de5ecf3 itself describes.
On the operator path, delete-before-apply narrows the window without closing it. The PackageSource watch map and Reconcile both read through the manager's cache (package_reconciler.go:980, :121, :131). Package and PackageSource are separate informers with no ordering between them. So the reconciler can see the new PackageSource while its Package cache still holds the deleted object. A reconcile already in flight for that Package does the same.
None of that ordering is pinned. Moving the apply back in front of prepareRegistration keeps every test in the touched packages green. So does making case derr != nil at :327 return nil, which is the fail-open that 2d6b12738 says cannot happen ("a fail-closed requeue that never applies the unsafe spec").
Fix: put the check where the install happens. In PackageReconciler, skip privileged install components for a Package that still carries the tap markers, and set a condition saying why. That applies to both the HelmRelease loop and resolvePrivilegedNamespaces. cozypkg add --allow-privileged already sheds the markers through pinRegistrationToUser, so the confirmed path keeps working. This covers every writer and every cache ordering, and delete-before-apply, the uncached reader and the conflict loop stop being needed for safety. A Reconcile test with the two objects above, asserting no label and no HelmRelease, pins it. Keying the check on an explicit confirmation instead of the tap markers would also cover a user-added Package whose variant later turns privileged. CodeRabbit raised that case, and it exists on main today.
B2: The cozypkg add handover has no test
Nothing tests the handover of a managed registration to the user. Replacing pinRegistrationToUser(installed, variant) at add.go:505 with a bare variant assignment keeps the suite green. The Package then keeps its ownerReference to the PackageSource, so pruning or untapping the source garbage-collects an install the user has just confirmed. TestPinRegistrationToUser covers the helper; nothing reaches installPackage. Extract the decision the way runUntap was extracted, and test it against a managed registration, a user's own Package and another tap's leftover.
B3: History that lands in main as is
Squash and rebase merges are off here, so every commit message below goes into main verbatim.

B5: The PR body becomes the merge commit message and still describes the three-commit version
Two claims in the body no longer hold. It says "cozypkg add treats an already-registered Package as done rather than erroring", but add now re-opens a managed registration for a variant choice and turns it into a plain user Package (add.go:497-510). cozypkg untap then refuses that Package without --yes. The Fix section says a Package is created "per materialized PackageSource". One is created only for a default variant with no privileged install components, and it is deleted again when a later revision makes that variant privileged. The Verification section covers the first three commits only, and the two CodeRabbit HTML markers are still there.

Deleting before this apply narrows the window but does not close it. The Package reconciler reads Package and PackageSource through separate informers, so it can still see the old Package next to the new spec. cozypkg tap also writes the PackageSource without passing through here at all. Moving the Patch above this call keeps every test green. See B1.

By this point the loop above has already applied the new artifact's PackageSource, variants included, while the managed Package still stands. If the new default variant is privileged, the Package reconciler acts on it before the operator has pulled the revision it would de-register on. See B1.

No test reaches this line. With a bare installed.Spec.Variant = variant here the suite stays green, and the Package keeps its ownerReference to the PackageSource, so pruning the source garbage-collects the install the user just confirmed.

Nothing reads this annotation since the readiness override was reverted; the Tap view reads only the tap label. Surface it on the Tap or drop it.

Connecting a marketplace repository materialized its PackageSource but created no Package, so its ApplicationDefinitions never rendered and its apps never appeared in the dashboard catalog until a manual `cozypkg add` the dashboard cannot drive (the package list is computed from the ApplicationDefinitions, which do not exist yet). The tap materializer now creates a tap-managed registration Package for each materialized PackageSource, the way the platform ships a Package per built-in app, so the ApplicationDefinition registrations deploy on connect and the apps become browsable; the app components carry no install block and are still instantiated per user resource. Privileged install components of an unconfirmed tap auto-registration (a Package that still carries the marketplace-tap label) are refused on several best-effort layers: the Package reconciler skips their HelmRelease and prunes a lingering one at the install site, and the PackageSource reconciler withholds their ExternalArtifact so the helm-controller has no privileged content to deploy, re-running on confirmation via a Package watch. `cozypkg add --allow-privileged` sheds the label as an explicit ownership handover, which is the confirmation; a platform Package never carries the label. A benign component flipped to privileged in a new revision can still be materialized by source-watcher before these layers observe the flip; closing that race fully requires decoupling the catalog registration from install and is tracked in issue #4359. `cozypkg untap` and the dashboard disconnect remove the registration Package (de-registering the apps) under a UID + ResourceVersion precondition, so a concurrent `cozypkg add` handover is never clobbered; running instances are left but unmanaged. `cozypkg add` re-opens a tap auto-registration for variant selection and hands it over. The cozystack-api ClusterRole gains delete on packages for the disconnect path. Assisted-by: LLM Signed-off-by: IvanHunters <xorokhotnikov@gmail.com>

Thanks — this is squashed to one building commit now, and the round-2 blockers are addressed as follows. B1 (privileged bypass). Done as prescribed: the check is at the install site. Two further layers close the paths a lingering artifact or release could take on a benign→privileged flip: The residual you named — a component flipped to privileged in a new revision, before any reconciler observes the flip — cannot be closed from these reconcilers: source-watcher materializes the new revision's content independently of them. Closing it fully needs the catalog registration decoupled from install (produce ApplicationDefinitions from PackageSource metadata and gate the whole install on an explicit confirmation label, not the content-derived flag). Filed as #4359 with the reproduction and the proposed fix. The "user-added Package whose variant later turns privileged" case you and CodeRabbit raised is the same class and is covered by that direction. B2 (handover untested). B3 (history). Squashed to a single commit that builds and passes on its own, with B4 (comments). The B5 (PR body). Updated to the current design. One addition on the teardown side: |

LGTM — connecting a tap can no longer install a privileged component without confirmation.
IvanHunters The check now sits inside the component that installs. A Package still carrying the tap label gets its privileged install components skipped, its target namespace left at the default PodSecurity level, and a HelmRelease left over from a revision where the component was still benign removed. Because the answer is read off the Package itself, it stops mattering which writer produced the PackageSource or in what order the two informers deliver the pair, so both bypasses from last round are closed rather than outrun.
I rebuilt both against this head rather than take the structure on trust. One reconciles a managed registration next to a PackageSource whose default variant is privileged, with the target namespace already present, which is where I watched an existing namespace pick up the privileged label. The other reconciles repeatedly against a Package cache still holding the object the operator would have deleted. Neither creates a privileged HelmRelease, neither raises the namespace, and both go red once collision.PrivilegedConfirmed is forced to return true, so they can fail.
The registration logic states in a breath now. A Package is absent, managed, handed over, or foreign, and managed means the tap label, a source annotation matching this tap, and an empty variant. cozypkg add performs the handover by shedding the label, the annotation and the PackageSource ownerRef in one update. The materializer creates managed, add moves managed to handed over, and the three teardown paths delete managed only. One predicate answers ownership at every call site, and the annotation that was written and never read is gone.
Twenty-three mutations, one at a time and restored after each, and twenty reddened the test names I wrote down first; the three that did not are in the notes below. 126 Go tests across the four changed packages pass, the chart suite is 12 of 12, and vet and gofmt are clean on every file the diff touches. Last round's closures survived the rewrite, the ClusterRole rule is unchanged from last round, and the commit carries a sign-off and exactly one Assisted-by: LLM.

Artifact withholding goes silent when it filters everything out. The early return on an empty outputArtifacts predates this change, so a source whose every install-marked component is privileged and unconfirmed keeps its previously generated ArtifactGenerator, still listing the artifact the filter meant to withhold. I reproduced it with one privileged component, an unconfirmed registration Package, and a generator from the earlier benign revision: the reconcile leaves that generator untouched. The install-site gate still refuses the HelmRelease so nothing privileged runs, but the comment above the filter says the helm-controller has no privileged content to upgrade from, and in that shape it does. Deleting the generator when filtering empties the list would close it.
The handover call site is still the mutation I named last round. Replacing handoverManagedRegistration in installPackage with a bare variant assignment and an update keeps every test green. The helper and the ownership decision are both pinned now, which is the extraction I asked for, so what is left uncovered is the two lines wiring them together. The damage is also smaller than it was, because that mutation leaves the tap label on, privileged install stays refused, and what breaks is the ownerRef garbage-collecting an install the operator just confirmed.
Three guards redden nothing when removed. Neither prune test puts a registration Package in its fixture, so dropping the registration delete out of pruneMaterialized is invisible; the ownerRef covers that outcome through garbage collection and the untap and disconnect paths are both pinned, so what is uncovered is the extra layer rather than the behaviour. Making autoRegisterSkipReason never skip is invisible too, so nothing holds a source without a default variant to staying unregistered. The Package watch that re-runs artifact generation on confirmation is the third.
Comment density on added lines still sits well above the files it lands in, 54% against 16% in rest.go and 37% against 11% in add.go. Most of it is rationale I would keep. A few restate the line under them, such as the one above the Get that checks the registration Package was created.

The withhold is complete only while some other component still produces an artifact. If every install-marked component of every variant is privileged and unconfirmed, outputArtifacts comes out empty and the zero-output early return below leaves an ArtifactGenerator from the earlier benign revision in place, still listing this artifact. I reproduced it: one privileged component, an unconfirmed registration Package, a generator from the previous revision, and the reconcile returns with that generator untouched. Nothing privileged installs, because the Package reconciler still refuses the HelmRelease, but the sentence above about the helm-controller having no privileged content to upgrade from is not true in that shape. Deleting the generator when filtering empties the list would make it true.

This call site is still the mutation from last round: a bare installed.Spec.Variant = variant plus an Update here keeps the whole suite green. TestHandoverManagedRegistration and TestManagedRegistration pin the helper and the decision, which is what I asked for, so the gap is now just the wiring. Not blocking, and the blast radius is smaller than before, since the mutation leaves the tap label on and privileged install stays refused; what breaks is the PackageSource ownerRef garbage-collecting an install the operator just confirmed.

Connecting a marketplace repository materialized its
PackageSourcebut created noPackage, so itsApplicationDefinitions never rendered and its apps never appeared in the dashboard catalog until a manualcozypkg add. The dashboard cannot drive that step: the package list it shows is computed from theApplicationDefinitions, which do not exist yet, a chicken-and-egg that leaves a connected repository unbrowsable.Fix
The tap materializer creates a tap-managed registration
Packagefor each materializedPackageSourcethat has adefaultvariant, the same way the platform ships aPackageper built-in app. Its install-marked components (theApplicationDefinitionregistrations) deploy on connect, so the apps become browsable; the app components carry noinstallblock and are still instantiated per user resource, so registration deploys no user workload.Privileged install components are not installed without confirmation. The check is at the install site: the Package reconciler skips a privileged install component of a Package that still carries the marketplace-tap label (a tap auto-registration the operator has not confirmed) and reports
Ready=False PrivilegedNotConfirmed, andresolvePrivilegedNamespacesgates the PodSecurity label on the same predicate.cozypkg add --allow-privilegedsheds the label (an explicit ownership handover), which is the confirmation; a platform Package never carries the label. Putting the check where the install happens closes the window a materializer-side guard would race, so the earlier install-safety de-register machinery is removed.Two further best-effort layers close the paths a lingering artifact or release could take when a source revision flips a previously benign component to privileged:
cleanupOrphanedHelmReleasestreats an unconfirmed privileged component as not-desired and removes a HelmRelease left from an earlier benign revision, and the PackageSource reconciler withholds a privileged component'sExternalArtifactuntil confirmed (re-running on confirmation through a Package watch), so the helm-controller has no privileged content to upgrade to. A component flipped to privileged in a new revision can still be materialized by source-watcher before any reconciler observes the flip; closing that race fully requires decoupling the catalog registration from install, tracked in #4359.cozypkg untapand the dashboard disconnect remove the registrationPackagetoo, so the apps de-register (its registration HelmReleases and theirApplicationDefinitions are garbage-collected); running instances are left in place but unmanaged until re-tapped, the same outcome ascozypkg del. Teardown deletes the Package under a UID + ResourceVersion precondition with a re-classify-on-conflict retry, so it never clobbers a Package a concurrentcozypkg addhandover has just confirmed.cozypkg addre-opens a tap auto-registration for variant selection and hands it over to the user.Verification
