feat(api)!: delete ClusterWatchRule scope, collapse every reference onto Flux's, and split the placement metric - #333
Merged
Conversation
…43.0 Four pages still advertised themselves as proposals for work that has since merged, which is the one failure mode the status labels exist to prevent. layout/model.md said "a proposal, not a plan of record. Nothing here binds" while every field it proposed is in the CRDs: spec.suspend, status.placement and the Ambiguous rule from #326, useKustomize and serializeNamespace from #328. Its own build table already said both PRs had shipped, so only the label disagreed with the page under it. created-root-namespace.md said "being built", and kustomization_bootstrap.go cites it by path as the reason a created root carries no namespace. Its history paragraph also credited #328 with writing namespace: into every root it created; that was the cut under review, not the cut that merged. gittarget-api-wave.md counted only steps 6 and 7 as shipped. Steps 2 to 5 shipped too, minus status.lastHandledReconcileAt, which #326 deliberately replaced with an in-memory tracker for a reason worth keeping next to the field's absence. Its version-strategy section predicted a growing graveyard of refused fields; measured on main, the residue is one field, because this wave removed its fields outright and paid for that in UPGRADING.md instead. placement-visibility-and-declared-defaults.md is now half built rather than mostly unbuilt: status.layout shipped as status.placement, and the ambiguous render root with it. Also sweeps the two backlogs those pages feed. TODO.md's output-layout item becomes the four questions model.md left open; the wildcard fan-out item shrinks to the PendingSample cap, which is all that survives a redefinition that deleted the fan-out rather than optimizing it; and two items are added for work that is breaking and therefore belongs in a breaking release: removing ClusterWatchRule.spec.rules[].scope, whose "removed one release from now" has stood since 0.39.0, and the reference-shape collapse among the wave's riders, which prunes defaulted group/kind fields with no error. open-asks-priority.md gets a second sweep note: #22, #11 and #10 are gone.

…nto Flux's, split the placement metric Three changes that are breaking, or breaking-adjacent, and therefore belong in a release that is already breaking. ClusterWatchRule.spec.rules[].scope is gone. It was the whole deprecation graveyard in the CRDs: retained since 0.39.0 purely so re-applying a manifest still saying "Namespaced" would fail, with a doc comment promising removal one release later. That was four minors ago. Which scope a rule watches is decided by which KIND you write, so the field had one legal value and no job. The compile-path refusal, its condition reason and its message go with it. ResourceScope survives as what it always was underneath: an internal matching vocabulary with no field in any CRD. The six reference shapes become two of Flux's. GitProviderReference, ClusterProviderReference, LocalTargetReference and LocalSecretReference each carried a defaulted, enum-of-one group/kind alongside the name, so four types existed to say "a GitProvider is a GitProvider". They are now meta.LocalObjectReference; NamespacedTargetReference is meta.NamespacedObjectReference. This is the quiet kind of breaking: the defaults meant every stored object persisted those fields, so the collapse prunes them with no error, which is why it goes in this release or in none. Flux's namespaced reference makes namespace optional, so ClusterWatchRule's targetRef keeps its "namespace is required" invariant as a CEL rule rather than by owning a struct; the MinLength=1 that our own types carried on name is kept the same way. KnownHostsReference stays ours, because its kind is a real two-member choice (ConfigMap or Secret) rather than an enum of one. The placement metric's source="declared" splits into by_type and default. A catch-all quietly answering for a type you meant to name explicitly was reported identically to the byType line working as intended, which is the one question the metric exists to answer. Not an API break, but it changes a label value a dashboard may select on, so it travels with the ones that are. Also drops a now-unreachable check that encryption.secretRef.kind is "Secret", and re-points the envtest that pins the apiserver's status-update behaviour onto a field that still exists: no field uses the loud-rejection pattern any more, but the property it rests on is worth keeping measured. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…e guides UPGRADING gains three entries: the reference collapse, the ClusterWatchRule scope removal, and the placement metric's label split. The scope entry's old "retained for one release as a loud rejection" section is marked superseded rather than deleted, because why the shim existed is still worth reading. The pre-upgrade inventory now covers all five kinds and says which rows carry a value to migrate and which are only a line to delete: nothing is lost when the removed field had exactly one legal value. architecture.md and configuration.md get the newcomer pass. Development history comes out — what a field used to be called, which release removed sibling inference, what a target "did before these fields existed" — because a guide should say what the thing does, and UPGRADING is where the before is already written down. "Why the two provider types have different scopes" loses two paragraphs of rationale it was restating in its own table. interpreting-metrics.md and new-file-placement-rules.md follow the metric split; the placement metric's `declared` value no longer exists. Deletes docs/bug-report.md: an incident report from a consumer, fixed by #263's audit-route attribution and confirmed adopted by the reporter. The one ask that outlived it — a ClusterProvider whose declared auditRoute has received zero facts should say so — moves into TODO.md, where it is now the highest-consequence silent failure on the list.

| | [`placement-visibility-and-declared-defaults.md`](design/placement-visibility-and-declared-defaults.md) | **design.** The three questions the inference deletion left, **decided and then not built**: PR #291 shipped the deletion and none of the eight items queued behind it. The residue was filed as [#295](https://github.com/ConfigButler/gitops-reverser/issues/295) — **which shipped in 0.42.1 via [#319](https://github.com/ConfigButler/gitops-reverser/pull/319) and is what reversed the layout model** — and [#296](https://github.com/ConfigButler/gitops-reverser/issues/296). Its Question 2 is superseded outright by [`layout/model.md`](layout/model.md). What still stands: keep `canonical` as the name for the built-in path and split `declared` into `byType`/`default`; **no CRD default for `placement.default`**, on the structural argument that a defaulted default is never empty and so shadows the kustomize-root rung; `status.layout` instead, over the `MarkTargetRetention` seam that already enqueues on change; and `{kindLower}`, not a `toLower` function | | ||
| | [`created-root-namespace.md`](design/created-root-namespace.md) | **design, decided.** One question with five answers: what namespace a `kustomization.yaml` the operator CREATES should carry. Decided **B, never write one** — `spec.serializeNamespace: false` means the artifact does not encode its deployment namespace, and adding a root must not quietly change that contract; the namespace comes from the documents when the field is unset or `true`, and from the installer (Flux `targetNamespace`, Argo `destination.namespace`) when it is `false`. Records the three facts an earlier draft got wrong (a namespace-less root is ordinary, both installers supply one, and what refused it was our own fidelity gate rather than kustomize), and carries the scoped fidelity rule that follows: the namespace is ignored in the render comparison ONLY when the governing root sets none, so a root that declares `namespace: shop` still rejects a live `billing` object. Also the sibling call: under `useKustomize` a placement no `resources:` list would name is refused rather than committed unrendered | | ||
| | [`gittarget-api-wave.md`](design/gittarget-api-wave.md) | **design**, filed as [#294](https://github.com/ConfigButler/gitops-reverser/issues/294). What is left of one breaking wave on `GitTarget` after the layout model reversed and left it: B4's `commitWindow`/`commit.message` move off the connection, the source-scope deletion (the only member that makes the API smaller), and the riders. Organizing principle: **the folder is described on the GitTarget, the connection describes only the connection** — and this is where that becomes a struct boundary rather than a sentence, since grouping a field is free only in a release that is already breaking. `spec.mode` and `GitTarget.spec.interval` are both **dropped**, with re-open triggers. Records that F9's envtest stays OUTSIDE the wave and gates it, and that staying `v1alpha3` on loud rejections is a **one-consumer countdown**, not a constant | | ||
| | [`placement-visibility-and-declared-defaults.md`](design/placement-visibility-and-declared-defaults.md) | **design, half built.** The three questions the inference deletion left, decided and then built in two goes. PR #291 shipped the deletion and none of the eight items queued behind it; the residue was filed as [#295](https://github.com/ConfigButler/gitops-reverser/issues/295) — **which shipped in 0.42.1 via [#319](https://github.com/ConfigButler/gitops-reverser/pull/319) and is what reversed the layout model** — and [#296](https://github.com/ConfigButler/gitops-reverser/issues/296), whose largest half then shipped in [#326](https://github.com/ConfigButler/gitops-reverser/pull/326): `status.layout` became `status.placement`, and the ambiguous render root came with it as a refusal rather than a third counter outcome. What still stands and is still unbuilt is the legibility set: split `declared` into `byType`/`default` (**the one row with an external consumer — it changes a metric label value a dashboard may select on**), the canonical path as a template constant, and `{kindLower}`. Its Question 2, a CRD default for `placement.default`, is **re-opened rather than superseded** and now lives as an open question in [`layout/model.md`](layout/model.md); the argument against it is legibility, since #319 removed the correctness objection | |

Include default placements in the fallback query.
The preceding table marks source="default" as a fallback that may need a byType rule, but the query under “Which types are falling back” selects only source="canonical". Users with a catch-all default will miss the placements this new label was added to expose. Use source=~"canonical|default" or provide a second query.

Every e2e manifest still spelled its references the old way, and kubectl does not prune quietly: strict field validation is its default, so each apply failed with `unknown field "spec.targetRef.kind"` and took 30 specs with it. That is worth more than the fix. The removal was documented as accepted-and- silently-pruned, which is only half true and the wrong half to lead with: a hand-applied manifest is REJECTED and names the field, while a client applying with field validation off accepts it and prunes. Both halves are now measured in docs/facts/crd-upgrade-strategies.md, UPGRADING.md says which client gets which, and the envtest that pins the quiet path says in its comment that it is deliberately taking the non-strict route.

…l notes
Collapsing our reference types onto Flux's dropped the MinLength=1 they carried
on name, and I restored it only on the provider and target references. The
three Secret references were left open, and one of them fails OPEN:
GitProvider.spec.secretRef reads an absent credential as anonymous access for a
public repository, so {name: ""} silently downgraded a private repository
instead of failing. The other two (encryption and commit signing) fail closed
at reconcile, which is still a regression from admission-time to runtime.
All three get the constraint back as a field-level CEL rule, which is where it
has to live now that the struct comes from another module. The generated schema
is compared against the pre-collapse one: same required list, same effect, so
this restores the old constraint rather than tightening it.
The pre-upgrade inventory missed ClusterWatchRule's targetRef and every
GitProvider Secret reference, including signing. It now walks every reference on
every kind, and the entry lists them in a table rather than a sentence that was
already incomplete when it was written.
Also drops two comments that still described the scope: Namespaced compile
refusal this branch deleted.

Collapsing onto Flux's LocalObjectReference took the kind out of the type,
which puts it on the field name: `{name: platform}` says nothing about what
`platform` is, so the field has to. Flux does exactly this — generic `sourceRef`
where several kinds are valid, specific `secretRef` and `certSecretRef` where
one is. Shipping the collapse without the renames would have adopted the half
of that convention that loses information.
GitTarget.spec.providerRef -> spec.gitProviderRef
WatchRule.spec.targetRef -> spec.gitTargetRef
ClusterWatchRule.spec.targetRef -> spec.gitTargetRef
CommitRequest.spec.targetRef -> spec.gitTargetRef
GitTarget is the case that earns it: `providerRef` sat directly beside
`clusterProviderRef`, so the shorter name read as "the provider" in the one
object that has two.
Everything else keeps its name because it already names its referent or its
role: clusterProviderRef, the three secretRefs, knownHostsRef, and the refs
inside kubeConfig.
Unlike every other removal in this release, no client can apply the old
spelling and be silently pruned: the new name is required, so a stale manifest
is rejected as an unknown field by a strict client and as a missing required
field by a non-strict one. What it does cost is a stall — a stored object stops
serving the old value the moment the CRDs land — which is the re-apply
UPGRADING already asks for in one sync, now applying to every object.
The one real hazard was GitTarget's immutability rule: the apply that migrates
a stored target is also the apply that first sets an immutable field, and a
plain `self.x == oldSelf.x` rejects it because oldSelf has no such key. That
would have forced delete-and-recreate on every target, and it is why a
two-release migration looked necessary. Guarding the rule on
`!has(oldSelf.gitProviderRef)` opens a one-way door instead: it cannot loosen
anything, because a required field is never absent on an object created from
here on. Measured both ways in TestRenamedRequiredField_StoredObjectCanAdoptIt,
which also gives the status-update envtest back a real subject.

Limit “buys nothing” to non-strict clients. Strict kubectl apply rejects removed fields and gives hand-applied manifests a migration signal. Clients using fieldValidation: Ignore accept and silently prune them. This client-dependent behavior affects the delete-out-right strategy used by the current upgrade guide.

🔎 Supported by static analysis
🌐 Web query:
For Kubernetes server-side apply and controller-runtime v0.24.1, does fieldValidation: Ignore permit unknown fields, or are apply requests always strict?
💡 Result:
For Kubernetes Server-Side Apply (SSA), apply requests are fundamentally strict regarding unknown fields, and this behavior is not overridden by setting a fieldValidation parameter [1][2]. Key details regarding your query: 1. Server-Side Apply Strictness: Unlike standard Create, Update, or Patch (JSON/Merge) requests, Server-Side Apply inherently requires that all fields sent in the request exist in the schema of the target resource [1][2]. If an apply request contains fields that do not exist in the object's schema, the API server will reject the request with an error [2]. 2. Role of fieldValidation: The fieldValidation query parameter (which supports Ignore, Warn, and Strict modes) is designed to control validation for standard operations like Create and Update [1][3][4]. It does not change the strict enforcement behavior of Server-Side Apply [2]. Even if a request explicitly sends fieldValidation=Ignore, the underlying Server-Side Apply mechanism continues to validate fields strictly against the schema [1][2]. 3. Controller-runtime v0.24.1: While controller-runtime v0.24.1 introduced new options for field validation configuration (e.g., adding FieldValidation to client.Options) [5][6], these settings apply to the standard client operations supported by those options [2]. They do not bypass the fundamental requirement that Server-Side Apply must be provided with a schema-compliant object [2]. To handle unknown fields when using SSA, developers typically need to perform manual filtering or normalization of the unstructured object before submitting the apply request [2].

This row combines controller-runtime writes with server-side apply. fieldValidation: Ignore does not bypass server-side apply schema validation. Split the row into non-apply behavior and server-side apply behavior.

The rename swept a kubectl jsonpath and turned core/v1 Endpoints' `addresses[].targetRef` into `gitTargetRef`, so the selector matched nothing, the helper saw zero endpoint addresses, and "should expose the controller service" failed on an empty list rather than on anything real. It reproduced three times before I read it properly — twice locally and once on CI's full-manager leg — which is what a mechanical rename across 140 files deserves. The rest of the diff was re-audited for the same mistake against every Kubernetes field that shares these names; this jsonpath was the only one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… forever A CommitRequest still pending when the rename lands serves an EMPTY gitTargetRef like every other object, and unlike every other object it cannot be repaired: its spec is wholly immutable, so no apply can put the name back. The reconciler passed that empty name to the router, which fetched `GitTarget ""`, failed, and retried on an object that will never resolve. It is now terminal — Stalled=True, reason GitTargetRefPruned — with a message saying to delete it, which is the only repair there is. An empty name is otherwise unreachable, because admission refuses one on every path, so the condition says exactly what happened rather than reporting a transient "get GitTarget" error for a permanent state. UPGRADING said CommitRequest needed no migration, on the reasoning that one-shot objects are never updated. That was the wrong half of the truth: they are never updated, which is precisely why this one cannot be fixed. The entry now asks for a drain before upgrading, with a query for pending requests and one for the stuck ones afterwards, and says plainly that nothing is lost from Git either way — an unfinalized request only means its writes were not flushed early. Also fixes a sample that pointed at a GitTarget no sample defines (`quickstart-gittarget`, where everything else uses `example-target`, which is also the chart's quickstart name), and four current-behaviour docs still spelling `spec.providerRef` or the `declared` metric value — both missed by the rename sweep, the first because the pattern excluded a preceding dot. The migration envtest now stores its object under a schema that really spells the field the old way, and asserts the old value is gone on READ before attempting the migrating apply. It previously created an object without the new field, which proved the guard worked but not the loss it exists for. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…uld change it The crispness pass cut a paragraph saying that a shared, platform-owned Git destination should be a separate cluster-scoped kind rather than a rescoped GitProvider. I read it as future-looking rationale; it was a recorded design decision, which is a different thing, and the question came straight back the moment it was gone. Restored in architecture.md, where rationale belongs rather than in the configuration guide, and extended with the two shapes that would actually solve the duplication it costs (an accessFrom policy on GitProvider, or a separate cluster-scoped kind, both additive) and with the constraint that rules out the obvious third: a CRD's spec.scope is immutable once the definition is Established, so converting GitProvider in place is not available at any price.

0.43.0 is already a breaking release, so this is the moment for the breaking
work that would otherwise have no home for months. Three changes, plus the
documentation round that follows them.
ClusterWatchRule.spec.rules[].scopeis goneIt was the entire deprecation graveyard in the CRDs. Retained since 0.39.0 so
that re-applying a manifest still saying
Namespacedwould fail loudly ratherthan be silently pruned, with a doc comment promising removal "one release from
now" — which was four minors ago. Which scope a rule watches is decided by which
KIND you write, so the field had one legal value and no job. The compile-path
refusal, its
ClusterScopeOnlyreason and its message go with it.ResourceScopesurvives as what it always was underneath: an internal matchingvocabulary with no field in any CRD.
Six reference shapes become two of Flux's
GitProviderReference,ClusterProviderReference,LocalTargetReferenceandLocalSecretReferenceeach carried a defaulted, enum-of-onegroup/kindbeside the name — four near-identical types existing to say that a GitProvider
is a GitProvider. They are now
meta.LocalObjectReference;NamespacedTargetReferenceismeta.NamespacedObjectReference, both fromfluxcd/pkg/apis/meta, which this repo already depends on.This is the quiet kind of breaking: the defaults meant every stored object
persisted those sub-fields, so the collapse prunes them with no error. Nothing
is lost — the pruned value was the only legal one — but it goes in a breaking
release or in none.
Two invariants move from struct shape to CEL, because Flux's types are
deliberately looser than ours were:
ClusterWatchRule.spec.targetRef.namespacestays required, and every reference keeps its non-empty
name.knownHostsRefkeeps its own type: itskindchooses between a ConfigMap anda Secret, which is a real choice rather than an enum of one.
The placement metric says which declaration answered
gitops_reverser_placements_total'ssource="declared"becomesby_typeanddefault. A catch-all quietly answering for a type you meant to nameexplicitly was reported identically to the
byTypeline working as intended,which is the one question the metric exists to answer. Not an API break, but it
changes a label value a dashboard may select on, so it travels with the ones
that are.
Documentation
UPGRADING.mdgains an entry for each of the three, and its pre-upgradeinventory now covers all five kinds, separating the rows that carry a value to
migrate from the rows that are only a line to delete.
architecture.mdandconfiguration.mdget a newcomer pass: developmenthistory comes out (what a field used to be called, which release removed
sibling inference, what a target did "before these fields existed") because a
guide should say what the thing does, and UPGRADING is where the before is
already written down.
A separate first commit reconciles the design tree with what shipped in #326,
#328 and #330 — four pages still advertised themselves as proposals for work
that has since merged — and sweeps the two backlogs they feed.
docs/bug-report.mdis deleted: a consumer incident report fixed by #263 andconfirmed adopted by the reporter. The one ask that outlived it (a
