feat!: one CommitRequest for the control cluster and source clusters, the applier's catch-up after saves, and late applier writes kept in the apply window - #456
BEGIN_COMMIT_OVERRIDE
feat!: one CommitRequest for the control cluster and source clusters, the applier's catch-up after saves, and late applier writes kept in the apply window (#456)
BREAKING CHANGE: the admission webhook is removed: drop the --admission-webhook, --admission-webhook-bind-address and --admission-webhook-cert-* flags and the chart's servers.admission values. A CommitRequest's author comes from its own audit event and is reported in status.author; the AuthorAttributed condition is gone, and a request no audit event names, on a cluster that sends them, ends AuthorUnresolved. A CommitRequest in progress is Ready=Unknown rather than Ready=False, spec.window.attachTimeout defaults to 5s, and a CommitRequest on the control cluster for a GitTarget that mirrors another cluster is refused NotAllowed. The chart renders its cert-manager Issuer only when it mints a certificate. See docs/UPGRADING.md, "The admission webhook is gone; a CommitRequest's author comes from audit".
END_COMMIT_OVERRIDE
Stacked on #455. Four of the gitops-api asks (docs/future/gitops-api-open-asks.md): #35, the kube-root-ca.crt vote, #34 (an e2e for their production topology), and saving from a source cluster, which #34's review led to. The #34 e2e found a bug in the apply window, fixed here. This branch also carries four review fixes to #455's generator write-back (below).
Saving went through two designs on this branch. The final one is in docs/review/20261027-save-request-simplification.md: one CommitRequest kind, served on the control cluster and on a source cluster through one core, with no admission webhook. It replaces the SaveRequest / RemoteSaveRequest pair and the window takeover the earlier commits built.
One CommitRequest, two ways in, one core
CommitRequest keeps its name and group from 0.54.0. It is now the one operator kind that can also live on a source cluster, next to the edits it saves.
On the control cluster, the CommitRequestReconciler picks it up with the operator's own client.
On a source cluster, the new CommitRequestServer watches the CommitRequests of every KubeProvider whose new spec.commitRequests is Reconcile or ReconcileAndDeleteFinished, through that provider's credential.
Both hand each step to commitRequestCore (internal/controller/commitrequest_core.go), which decides everything else once: admission, the author, the attach and its outcome, the apply catchUp: AfterPush asked for, and retention. So attach: Next, whenNothingToCommit: CommitEmpty, the phase reasons and commit_requests_total reach source-cluster requests too, and a fix is made once.
Which path serves a request. The named GitTarget's KubeProvider alone picks the owner: the control-cluster path for an inCluster provider, that provider's watch for a kubeconfig. Three rules keep several observers of one request safe:
A path that is not the owner writes only GitTargetNotFound, once attachTimeout has passed with no GitTarget, and only into an empty status.
Every status write is conditional on the resourceVersion it was decided from. A conflict re-reads and decides again.
The owner claims a request by writing its first status (status.author, Ready=Unknown, reason Saving) before it attaches. If the claim conflicts and an outcome is already there, it stops without saving. After the claim, a conflict re-applies the worker's outcome and never restarts the save. Ownership is structural, so after a restart the owner resumes its own claim.
This also fixes a race in the earlier source-side server, where two providers watching one cluster could each refuse the other's request. A control-cluster request for a GitTarget that mirrors another cluster is NotAllowed when that provider serves no CommitRequests, and left to the provider's watch when it does (its kubeconfig may point back here). A request on a source cluster must name the GitTarget's namespace, or it is not picked up.
The author comes from audit, on both paths. The core looks the request's own audit fact up in the same index as the edits', on the route of the GitTarget's KubeProvider, keyed by the uid and resourceVersion it was created with, within --author-attribution-grace. The control-cluster path now acquires the fact stream of commitrequests, which it never did. The wait runs whenever attribution is on. A request no fact names, on a provider that has received audit facts, is AuthorUnresolved and saves nothing; on one that has not, it names nobody and saves the unnamed window. spec.window.attachTimeout defaults to 5s, as the request now waits for its own audit event as its edits do.
Admission.GitTarget.spec.allowedCommitRequests grants set exactly one of consumerNamespaces (control-cluster namespaces, from: Same|Names|Selector|All) and sourceNamespaces (names or "*" on the mirrored cluster, never one the KubeProvider does not lend the GitTarget), enforced in CEL. Omitted, the list is [{consumerNamespaces: {from: Same}}], with an API-server default, no omitempty, a Go mirror and TestGrantDefaultsMatchCRDs, so a single-cluster user writes what they did in 0.54.0. The GitTarget that admitted a request is recorded in status.gitTargetUID; a replacement must admit it again.
The source-cluster side.
spec.commitRequests
What GitOps Reverser does
The credential needs
Ignore (default)
nothing
nothing
Reconcile
serves the requests in the namespaces the KubeProvider lends its GitTargets, and writes their status; a finished request stays
get, list, watch; update on commitrequests/status
ReconcileAndDeleteFinished
as Reconcile, and stamps configbutler.ai/delete-after on a finished request, and deletes it once that has passed
as Reconcile, plus patch and delete
CEL takes only Ignore beside inCluster. A provider watches only the namespaces it lends (one watch across the cluster when a grant lends "*"), so a namespace-scoped credential is enough. It reports what it watches in status.commitRequests.namespaces and in a new CommitRequestsServed condition, outside Ready and removed on Ignore: Watching, NothingToWatch, CRDNotInstalled, VersionNotServed, Forbidden, Unreachable, each message with its fix, at priority=1 as Saves. GitOps Reverser never writes the CRD. It ships on its own as the release asset commitrequest-crd.yaml, and carries its schema revision as the last line of the kind's description ("Schema revision 1, compatible from revision 1."), guarded by a hash test that fails when the CRD changes without a revision bump. The default watch policy excludes configbutler.ai/commitrequests.
Retention keeps 0.54.0's delete-after contract on both paths: always on the control cluster, on a source cluster only with ReconcileAndDeleteFinished.
The admission webhook is gone
The default install paid for the validate-operator-types webhook and got nothing for saves: without Redis its command-author store was nil. It goes completely, with /validate-all (an always-allow e2e endpoint matching every write), the Redis command-author store, the --admission-webhook* flags, the chart's servers.admission values, its Certificate and ValidatingWebhookConfiguration, config/webhook, and docs/spec/commitrequest-admission-authorship.md. The WatchRule feedback it gave stays where it was enforced: the writer refuses the configuration, and the GitTarget reports MultipleSourceNamespaces. Takeover (spec.window.author, unattributedWindows, the Saved-By and Author-Source trailers) goes with it, because only admission could name a taker.
cert-manager only for a certificate. The chart renders its self-signed Issuer only when it mints a certificate: the audit ingress certificates with attribution, or the metrics certificate with metrics TLS. The default install needs no cert-manager, and the quickstart moves that step under named commit authors.
spec.catchUpAfter on FluxClaim and ArgoCDClaim (#35)
A push of GitOps Reverser's own asks no apply, because the flush already put its edits on the cluster. Since 0.54.0 that left the applier's own state behind the branch until somebody else pushed: a Kustomization's status.lastAppliedRevision, its GitRepository's artifact, and anything that reads them (Flux commit-status notifications, gitops-api's publish of what was applied).
Once an applier has been behind the tip for spec.catchUpAfter, a converge (CatchUp) becomes pending for it. The clock starts on the first pass that finds the applier behind, and again on every send. A burst of saves costs one apply, and an applier already at the tip costs nothing. The interval is when the apply is asked for, not a deadline: the converge then waits for the barrier, a backoff and the flush like any other reason.
Setting 0s also drops a converge that only the interval left pending. A converge something else asked for, such as a save's, stays.
FluxClaim defaults to 1m. ArgoCDClaim defaults to 0s (off): a sync runs hooks, and Argo CD's refresh already compares the live state against the tip.
An interval converge yields to an edit. Its ApplyRequest.Current stops holding once a live edit is mirrored after the send, and the converge waits a fresh interval. ForeignCommit, Repair, Refusal and the startup converge are unchanged, so continuous editing still cannot starve them (S1).
CommitRequest.spec.catchUp
AsDefinedOnClaim (the default) leaves the apply to the claim's catchUpAfter. AfterPush makes a converge pending for the GitTarget's applier right after the save's commit is pushed; it does not yield to an edit. The request reports the apply in an Applied condition and status.appliedRevision, and never changes Ready:
Unknown, Applying or Retrying: the apply runs, or failed and is retried.
True, Applied: the applier applied a revision that holds the commit.
True, NothingToApply, NoApplierClaim or ApplierGone: no apply was needed.
False, CommitDropped: the branch lost the commit. The only False.
Unknown, Lost: GitOps Reverser restarted before it learned how the apply went.
A second save of one author on one GitTarget, made while the first still waits for a window or collects one, is refused at once with SaveInProgress (and commit_requests_total{outcome="save_in_progress"}), since a window carries one message.
kube-root-ca.crt is never mirrored
The cluster writes it into every namespace, it holds that one cluster's CA, and the cluster overwrites any other value. Both gatherings leave it out, counted as watch_events_total{outcome="cluster_generated"}. A copy already in Git is treated like any document the cluster does not hold (see UPGRADING.md).
A source-cluster scenario runs gitops-api's production setup: a Kustomization in flux-system applies a folder into a kcp workspace through spec.kubeConfig, the GitTarget mirrors that workspace through a secretRefKubeProvider, and the FluxClaim holds the Kustomization through the install's own provider. The specs:
Naming the FluxClaim applies a Git-side change the GitRepository's 24h interval never fetched.
One withheld collision, read from the remote object's managedFields: an edit Flux reverts stays in Git, and a Repair puts it back.
A CommitRequest on the control cluster for the workspace's GitTarget is NotAllowed. Once the CRD is in the workspace and the provider sets ReconcileAndDeleteFinished, the KubeProvider reports CommitRequestsServed=True, a request in the workspace is refused until the GitTarget grants its namespace in sourceNamespaces, and then Committed with its message, stamped for deletion, and Applied=True.
Two workspace saves that catch up, each Committed and Applied=True.
The apply window waits for the watch
An apply window judged a write by when its event reached the branch worker, and closed 10s after the operation completed. On a source cluster that sends no audit facts each event waits the whole attribution grace, so the applier's writes arrived after the window closed, and a revert of an edit was mirrored as an edit. Now, once an operation completes, its window takes a barrier: the newest resourceVersion of every stream's collection, which each stream answers once it handled an event or bookmark at or past it. The window stays open for its grace and until every stream answered, for at most two minutes. apply_window_barriers_total{outcome} counts met, timed_out and failed. docs/review/20261026-apply-window-late-events.md explains the bug.
An input a HelmRelease or Argo CD Application also names as a values file counts as shared: deleting the generated ConfigMap keeps it, and a write into it is refused.
A generator entry is found by its name and namespace, not by the index it had before the batch.
The render check keys a generated object by its namespace too.
A live object the generator already renders plans no write, so it needs no writable input.
Validation
task lint and task test pass (unit coverage 82.5%); locally the only lint failures come from an uncommitted WIP doc that is not part of this branch. The design doc's acceptance tests are in internal/controller/commitrequest_core_test.go and commitrequest_server_test.go: overlapping observers of one cluster (the namespace omitted and set), two kubeconfig providers on one source cluster, both race orders of a GitTarget created during the attach wait, a conflict after the outcome, a restart while Saving, a delayed audit fact, retention on both paths, attach: Next and CommitEmpty on the source path, the CRD discovery reasons, and the server end to end over a fake source cluster. The main e2e suite asserts that a control-cluster save's author comes from audit and authored its commit. Locally, the main e2e suite ran 111 specs with one failure, the Flux applier's catch-up save, which ended NoWindow: a request is now registered only once its own audit event names its author, so on a GitTarget whose windows close on the first silence its edit could commit first. The two specs that save before they edit now wait for the claim (Ready=Unknown), as configuration.md and UPGRADING now say, and the flux-applier and commit-request specs pass on the fix (11 of 11). The source-cluster and bi-directional corners run in CI.

Walkthrough
This change adds timed and request-driven catch-up for Flux and Argo CD appliers, CommitRequest apply reporting and author options for unattributed windows, apply-window watch barriers, root CA ConfigMap filtering, and namespace-aware generated ConfigMap write planning.
Changes: Applier catch-up and CommitRequest behavior

Summary
Catch-up API and request contracts api/v1alpha3/*claim_types.go, api/v1alpha3/commitrequest_types.go, api/v1alpha3/gittarget_types.go, api/v1alpha3/zz_generated.deepcopy.go, config/crd/bases/*, hack/crdfields/fields.yaml, docs/configuration.md, docs/UPGRADING.md, docs/design/apply-trigger.md
FluxClaim defaults catchUpAfter to 1m; ArgoCDClaim defaults it to 0s. CommitRequest adds catchUp and window-author options, plus Applied status reporting. GitTarget adds an unattributed-window policy.
Workers schedule interval-based converges and track CommitRequest applies against pushed commits. AfterPush requests an immediate converge. The controller reports the Applied condition and applied revision; tests cover timed and request-driven apply outcomes.
A request can claim an unattributed window when the GitTarget policy allows it and the provider has not received audit facts. SavedBy preserves the missing author and adds a trailer; TakeOver uses the submitter as author and adds a different trailer.
After an apply completes, the worker can keep the apply window open while watch streams process resource-version marks. The wait ends when all streams answer, setup fails, or the two-minute limit expires. Barrier outcomes are recorded in telemetry.

Snapshot and live-watch processing omit kube-root-ca.crt from desired resources. Live events advance the cursor without enqueueing writes and contribute to the cluster_generated outcome.
Generator entries and write intents identify generated objects by name and namespace. Manifest edits locate a unique matching generator entry rather than relying on its position.
Write planning skips unchanged rendered objects and accounts for files also used as HelmRelease values files. Tests cover shared inputs, namespace-distinct objects, and batched generator deletion.

Merge Risk: Moderate · previous review 49e66
Two apply-window barrier defects should be fixed before merge. A successor apply window can stay open too long and misjudge real edits as applier echoes. A hung source-cluster list can pile up background work across applies. A stale catch-up attempt can also leave a save's Applied status unresolved. Two small documentation issues remain open.

Update the ApplyOperation.Reason description for the new CatchUp triggers.
The doc comment says CatchUp covers only "adopting objects the API created, and once at startup or when a GitTarget first names the claim". This PR adds two more sources of a CatchUp operation:
The spec.catchUpAfter interval converge.
CommitRequest.spec.catchUp: ImmediatelyAfterPush.
An operator who reads status.operation.reason: CatchUp in kubectl explain gets an incomplete list of causes.
Extend the sentence. Then regenerate the CRDs, because the same text appears in configbutler.ai_fluxclaims.yaml and configbutler.ai_argocdclaims.yaml. Keep every line within 76 characters.
As per coding guidelines: "Keep CRD descriptions to the contract ... say what the field does, what its values mean, and the gotchas".

Return carried saves from a lag-only ApplyStale attempt.
onlyLag does not exclude waiting saves, so an attempt can have both attempt.lag == true and attempt.saves. The ApplyStale branch resets the lag timer and continues without restoring those saves or scheduling a normal converge. The saves are then discarded without recording a result, so their CommitRequest outcomes can remain unresolved.
Proposed fix

if attempt.lag {
+ if len(attempt.saves) > 0 {+ // The attempt carried saves, so it is not a lag-only converge.+ state.converge, state.lag = true, false+ for id, commit := range attempt.saves {+ state.waitSave(id, commit)+ }+ continue+ }
// It yielded to an edit, or to a newer tip: it only catches the applier's state

The cluster's root CA publisher writes kube-root-ca.crt into every
namespace. It holds that one cluster's CA, changes on every rebuild, and
the publisher overwrites any other value, so a copy in Git can be neither
edited nor restored. Mirroring it only produced a committer-authored
reconcile commit per namespace on every cluster rebuild.
Both gatherings now leave it out: the snapshot fold (desiredFromObject)
and the live route, which counts each dropped event as
watch_events_total{outcome="cluster_generated"}. A snapshot that left it
out says so in one info line. A copy already in Git is treated like any
document the cluster does not hold: prune mode Always sweeps it,
OnEvent leaves it for a human to delete.

…c.convergeInterval
A push of GitOps Reverser's own asks no apply: the flush already put its
edits on the cluster. But the applier's own state stayed behind the
branch until somebody else pushed: a Kustomization's
status.lastAppliedRevision and its GitRepository's artifact, and
whatever reads them (Flux commit-status notifications, a step that
publishes what was applied).
FluxClaim and ArgoCDClaim gain spec.convergeInterval. Once an applier has
stayed behind the tip that long, a converge (CatchUp) is pending for it.
The clock starts on the first pass that finds it behind and again on
every send, so a burst of saves costs one apply and an applier at the tip
costs nothing. The interval is read from the claim on every pass that
finds the applier behind, so a change applies from the next wake.
FluxClaim defaults to 1m; ArgoCDClaim to 0s, since a sync runs hooks.
An interval converge yields to an edit: its fetch writes nothing to the
cluster, but its apply would put a tip that lacks an edit mirrored after
the send, flipping that object until a Repair. Its decision
(ApplyRequest.Current, asked just before the resume) stops holding once
a live edit is mirrored after the send, and it waits a fresh interval.
Every other reason applies regardless, as S1 requires.
The e2e FluxClaims pin 0s, so the specs that count applies keep counting
only the ones an edit or a push asks for; a new Manager Flux Applier spec
sets 10s and waits for lastAppliedRevision and the artifact to reach the
tip of a mirrored API edit.

… once; convergeInterval is catchUpAfter
The claim field is renamed catchUpAfter: it is how long the applier may
stay behind the branch before it catches up, and the apply shows as
reason CatchUp. "Reconcile" would suggest Flux's periodic drift
correction, which the claim turns off.
A CommitRequest gains spec.catchUp. "AsDefinedOnClaim" (the default)
leaves the apply to the claim's catchUpAfter; "ImmediatelyAfterPush"
leaves a converge pending for the GitTarget's applier as soon as the
save's commit is pushed. It was asked for, so it does not yield to an
edit. A save that pushes no commit, or whose GitTarget names no applier
claim, asks nothing. The field is immutable like the rest of the spec.
The Manager Flux Applier converge spec now times an UPDATE: a create is
adopted at once, so it never proved the interval. The failed-apply spec
takes its ConfigMap out of Git before its namespace goes, which left
every later apply of the folder failing.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…condition
A CommitRequest with catchUp: ImmediatelyAfterPush now reports how the
apply it asked for went, beside Ready and never changing it: Ready stays
"the save is pushed".
- Unknown, Applying or Retrying: the apply runs, or did not complete
and is asked again with the applier's backoff; the message says why.
- True, Applied: status.appliedRevision names what the applier applied.
- False, NothingPushed, NoApplierClaim or ApplierGone: nothing to apply,
or no applier to ask.
- Unknown, Lost: GitOps Reverser restarted before it learnt.
The branch worker keeps, per applier, the saves waiting for an apply. The
attempt sent next carries them, so the one that succeeds settles them
(any apply sent after a save's push holds its commit); one that does not
gives them back. An applier already at the tip settles them without an
apply. The controller follows a Ready request that asked to catch up
until Applied is settled, then expires it as any finished request.

…ies by identity
Four fixes to writing a live ConfigMap back into its configMapGenerator:
- An input a HelmRelease or Argo CD Application also names as a values
file counts as shared: a delete of the generated ConfigMap keeps it,
and a write into it is refused, since the kustomize render cannot show
what the edit does to the release.
- A generator entry is found in the kustomization's bytes as they stand,
by its name and namespace, not by the index it had before the batch.
Deleting two generated ConfigMaps of one kustomization in one flush no
longer aborts the second.
- The render check keys a generated object by its namespace too, so two
entries of one name in different namespaces are two objects: deleting
or writing one is checked against that one.
- A live object the generator already renders plans no write, so it
needs no input it may write: a generator in a read-only base, or one
two render roots share, no longer fails a resync that changes nothing.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
… catchUp is AfterPush
- spec.catchUp "ImmediatelyAfterPush" is "AfterPush".
- A save waiting for its apply keeps the commit it pushed, and is
settled Applied only when the applied revision holds that commit. One
whose commit a force-push dropped from the branch is False,
CommitDropped; one whose applied revision the checkout does not hold
yet keeps waiting while the remote is looked at.
- A save whose GitTarget names no applier claim, or stopped naming the
one asked, is Applied=True (NoApplierClaim, ApplierGone): nothing
applies the branch, and the cluster already holds what was saved.
- catchUpAfter "0s" drops a converge only its interval left pending,
waiting behind the barrier or a backoff; one a save asked for stays.
- The descriptions say when an apply is asked for rather than promise
how long the applier may lag, name the latest tip rather than the
request's commit, explain Ready, Pushed and Applied together, and list
the timed and save-asked catch-ups among the claims' triggers.

…ingToApply
A request that pushed no commit has its content in Git already and on the
cluster, so it is Applied=True with reason NothingToApply, as one whose
GitTarget names no applier is. Applied=False is left for something wrong:
CommitDropped, a commit the branch no longer holds. A client waiting for
Applied=True never sees False for a save that went fine.

Scenario 10 of the source-cluster corner is gitops-api's production
topology (ask #34): a Kustomization in flux-system applies into a kcp
workspace through spec.kubeConfig, the GitTarget mirrors that workspace
through a secretRef KubeProvider, and the FluxClaim holds the
Kustomization through the install's own provider.
It shows the startup converge landing in the workspace, an edit made in
the workspace during an apply withheld from the apply's revert (E5's
sequence, now shared as echoRun.editDuringApply, plus the withheld
apply_window_collisions_total going up), and two saves with catchUp
AfterPush both reaching Applied=True.

…from a cluster that sends no audit facts
A CommitRequest attached only to a window whose author matched its
submitter's. A write on a cluster with no audit stream names no author,
so a save there could never attach: it ended WindowMismatch.
When the GitTarget's KubeProvider has never received an audit fact
(AuditFactsReceived is not True, read from its status), a request that
names its submitter now also takes over a window on its GitTarget whose
writes name no author. The submitter authors the commit, and the message
ends with "Author-Source: CommitRequest <namespace>/<name>; no audit
record names who made these changes". Once the provider has received a
fact, a write naming no author means its fact went missing, and its
window stays another's.
The source-cluster Flux spec now saves real edits in the kcp workspace
this way, and accepts ForeignCommit as well as CatchUp as the reason for
the apply that follows naming the FluxClaim.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
LookupCommitRequestApply answered a request whose GitTarget is gone with
Done and reason ApplierGone, but left Applied false, so the controller
wrote Applied=False. ApplierGone means no apply was needed, and the
contract says only CommitDropped is Applied=False; dropSaves already set
Applied for the same reason.

… opt-in, as SavedBy or TakeOver
The takeover in the previous commit claimed such a window automatically
whenever the GitTarget's KubeProvider had never received an audit fact.
Every write that names no author shares one window, whoever made it, so
that named a save's submitter as the author of other people's edits.
Claiming is now asked for and allowed explicitly:
- CommitRequest spec.window.author: "Own" (default), "SavedBy" or
"TakeOver" says what a save asks for.
- GitTarget spec.commit.unattributedWindows: "Keep" (default),
"SavedBy" or "TakeOver" bounds what a save on it may claim.
- "SavedBy" gives the window the request's message and names no author;
the message ends with "Saved-By: <submitter>". "TakeOver" makes the
submitter the author, with the Author-Source trailer.
- A request that asks for more than its GitTarget allows fails at first
sight: Ready=False, Stalled=True, reason TakeOverNotAllowed.
- Both act only while the KubeProvider's AuditFactsReceived is not True.

…lier's writes
An apply window judges a write by when its event reaches the branch
worker. It closed 10s after the operation completed. Every event waits
for its audit fact in turn, and on a source cluster that sends none
each waits the whole attribution grace, so the applier's writes reached
the worker after the window had closed. Mirrored then, a write that
reverted an edit made during the apply put the revert in Git and lost
the edit; the source-cluster e2e showed Flux's writes arriving 12s
after the window closed.
Now, once the operation completes, the window takes a barrier: for each
GitTarget the applier covers, the watch lists every stream's collection
and takes the newest object resourceVersion. Each stream answers once
it has handled an event or bookmark at or past it, on the worker's
queue behind every event it routed first. The window stays open for
its grace and until every stream answered, for at most two minutes.
apply_window_barriers_total{outcome} counts met, timed_out and failed
barriers. A source whose resourceVersions are not numbers fails the
barrier and keeps the grace alone, as before.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…t arrives
E5 edits once the apply was asked for and races Flux, which often wrote
first, so the source-cluster spec counted no collision. On a kcp
workspace every event waits out the attribution grace, so an edit made
just before a Git-side push reaches the worker after the push's apply
was asked for and applied: Flux reverts it, and the apply window, which
now waits for the watch, withholds that write.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…eRequest created there
A CommitRequest lives in the cluster GitOps Reverser runs in, so the
people who edit a source cluster, such as a kcp workspace, need access
to that cluster to save, and the save's author comes from its admission
webhook rather than from the audit stream their edits are attributed
from.
SaveRequest (source.configbutler.ai/v1alpha1) is created on the source
cluster itself. It names no GitTarget: it saves the commit window of
every GitTarget that mirrors its namespace from that cluster, with its
message and timers, and reports each commit and, with catchUp
AfterPush, each apply in status.targets and the Ready and Applied
conditions.
- A KubeProvider serves its cluster's SaveRequests only with
spec.saveRequests: Enabled; that is GitOps Reverser's one write on a
source cluster (status, and delete for the finished-request TTL).
- The request's author is found from the source cluster's audit facts,
as its edits' authors are. With no audit it names nobody and attaches
to a window that names nobody. On a provider that has received an
audit fact, a request no fact names is refused with AuthorUnresolved.
- SaveRequests are never mirrored: the default watch policy excludes
them.

…nd its setup
A window opened while the one before still waited for the watch took
that barrier's two-minute limit as its carried close time, so it stayed
open until then even after both barriers were met. It now carries the
pending barrier itself: the earlier apply's writes are judged until that
barrier is met or lapses, its answers still count after the
replacement, and the new window closes after its own grace and barrier.
Taking a barrier lists the source clusters on the worker's lifetime
context; it now runs under the window's limit, so a hanging list cannot
outlive the wait it serves.

…erge
onlyLag did not look at the saves waiting for an apply. Today every save
also clears lag, so an attempt never carried both, but a lag-only attempt
that goes stale is not given back, and its saves would have been lost
with it. onlyLag now answers no when a save is waiting.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…RemoteSaveRequest
The two request kinds are named as one pair. SaveRequest
(configbutler.ai/v1alpha3, the former CommitRequest) is created on the
cluster GitOps Reverser runs in and names its GitTarget; its author
comes from admission. RemoteSaveRequest (source.configbutler.ai/v1alpha1,
the source-cluster kind this branch added as SaveRequest) is created on
a source cluster, names no GitTarget, and is attributed from that
cluster's audit events. KubeProvider.spec.saveRequests is
spec.remoteSaveRequests.
Everything named after CommitRequest follows it: the RBAC resource, the
--save-request-ttl flag and controllerManager.saveRequestTTL value, the
save_requests_total metric, and the save_request values of
message_source and timer_source.
BREAKING CHANGE: CommitRequest is SaveRequest. Grant saverequests
instead of commitrequests, rename --commit-request-ttl to
--save-request-ttl and controllerManager.commitRequestTTL to
saveRequestTTL, read gitopsreverser_save_requests_total, and delete the
commitrequests.configbutler.ai CRD after upgrading.

… save holds only its namespace's edits
Three gaps an API review found in the source-cluster save:
- A save was not confined to its namespace. A commit window groups by
GitTarget and author, so a save from one namespace could commit the
same author's edits in another, or, on a cluster without audit,
anyone's. A RemoteSaveRequest now attaches only to a window whose
writes are all in its namespace; once it has, a write anywhere else,
cluster-scoped ones included, opens a window of its own. A window
that already holds writes from elsewhere is left alone, and the save
ends WindowOutsideNamespace.
- A cluster-scoped watch matched every namespace: a collection with no
namespace is both "cluster-scoped" and "every namespace". The match
now reads the GitTarget's watched types and counts namespaced ones.
- The GitTarget's owner could not consent. Enabling the requests on a
KubeProvider made every mirroring GitTarget eligible, and a request
steers a window's message, its timers and an apply. The provider's
switch now only makes them reachable: GitTarget
spec.allowedRemoteSaveRequests admits them by source namespace (names
or "*") and an optional requestSelector, and admits none when
omitted. A request a mirroring GitTarget does not admit is
Ready=False, Stalled=True, NotAllowed.
status.targets is status.gitTargets, a list keyed by the GitTarget's
namespace and name.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…s it in spec.allowedSaveRequests
A SaveRequest's spec.gitTargetRef takes a namespace, so a request can
save a GitTarget outside its own namespace. The GitTarget consents in
spec.allowedSaveRequests, a grant list like the others: omitted, it is
one from: Same grant, so a request in the GitTarget's namespace saves
as before; [] admits nobody. A request no grant admits fails at first
sight with reason NotAllowed.
spec.commit.unattributedWindows moves into each grant, so a request
from another namespace claims of a window whose writes name no author
only what the grant admitting it allows; admitted by several, it may
claim the most any of them allows.
A RemoteSaveRequest is no longer confined to its namespace's edits: a
commit window groups by GitTarget and author, and the GitTarget's
spec.allowedRemoteSaveRequests is what authorizes saving its creator's
whole window there. WindowOutsideNamespace is gone.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…progress, and admit by GitTarget UID
A RemoteSaveRequest names its GitTarget in a required spec.gitTargetRef
(namespace and name on the cluster GitOps Reverser runs in) and saves
that one. Reaching every admitting GitTarget that mirrors its namespace
made an unchanged request do more whenever a GitTarget was added, and
discovery that had not caught up after a start reported NoGitTarget.
The GitTarget must mirror the cluster the request came from and admit
it in spec.allowedRemoteSaveRequests; status is flat (commit,
appliedRevision, Ready, Applied). A request served again after a
restart keeps the author found when it was first served, since its
status writes moved its resourceVersion, and keeps an outcome already
decided, following only its apply.
A second save of one author on one GitTarget, made while the first
still waits for a window or collects one, is refused at once with
SaveInProgress: a window carries one message, and the second would lose
its own without a word. A save for the Next window is not refused by a
collecting one, which it closes first. save_requests_total gains
outcome save_in_progress.
A SaveRequest records the UID of the GitTarget that admitted it in
status.gitTargetUID. Nothing is attached before one did, so a GitTarget
created after the request under the same name must admit it; only a
refusal by the GitTarget that admitted it is set aside, for a request
an attach may already have reached.
docs/design/concurrent-author-windows.md proposes a window per author,
open side by side, for the split a second person's edit causes.

…finish a lost apply
An attach now carries the UID of the GitTarget that admitted the request. A
GitTarget of that name with another UID replaced it and admitted nothing, so
the router treats it as gone instead of handing the request to its worker.
- RemoteSaveRequest: a request whose GitTarget is replaced while no worker
holds it is admitted again by the replacement before it is attached, and
is refused (NotAllowed) when its grants do not admit it.
- SaveRequest: a replacement that refuses a request no longer fails it at
once. The worker the first GitTarget sent it to answers first: a commit it
made is reported, a request it holds is waited for, and the refusal is
written only once the request is withdrawn or nothing held it.
- RemoteSaveRequest: Applied=Unknown with reason Lost is a decided apply, as
on SaveRequest, so the request finishes and expires after its TTL instead
of being served again forever.

The design for collapsing SaveRequest and RemoteSaveRequest into one
CommitRequest kind served by two front ends over one core, with the
admission webhook and takeover removed. configuration.md gains the table
of what each remoteSaveRequests value does and what the credential needs,
which the implementation replaces with the three-value table.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Undo the SaveRequest rename of b86dffb for the kind: its Go type and
files, the commitrequests.configbutler.ai CRD and its RBAC, the
--commit-request-ttl flag and controllerManager.commitRequestTTL value,
gitopsreverser_commit_requests_total, and the commit_request values of
message_source and timer_source. These are their names in 0.54.0, so the
UPGRADING entry for the rename goes with it.
The source-cluster kind keeps its RemoteSaveRequest name until it is
folded into CommitRequest.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A CommitRequest's author came from the validate-operator-types webhook,
captured into a Redis command-author store. Both are gone, with the
always-allow /validate-all endpoint the e2e system under test installed,
the --admission-webhook* flags, the chart's servers.admission values,
its Certificate and ValidatingWebhookConfiguration, and the WatchRule
feedback the endpoint gave (the GitTarget still reports it as
MultipleSourceNamespaces). The AuthorAttributed condition goes with
them.
Takeover existed only because admission could name a taker: a request's
spec.window.author (SavedBy, TakeOver), a grant's unattributedWindows,
the TakeOverNotAllowed reason and the Saved-By and Author-Source commit
trailers are removed. Until the shared core takes a request's author
from audit, a CommitRequest names no author.
BREAKING CHANGE: the admission webhook is removed. Drop the
--admission-webhook, --admission-webhook-bind-address and
--admission-webhook-cert-* flags and the chart's servers.admission
values; CommitRequest loses spec.window.author and the AuthorAttributed
condition, and allowedCommitRequests grants lose unattributedWindows.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…r from audit
A CommitRequest is served by commitRequestCore, which decides every
step from the object as it is stored, so the control-cluster reconciler
is a thin front end, and the source-cluster watch can become another:
- The named GitTarget's KubeProvider alone picks the path that owns a
request. On the control cluster that is an inCluster provider. One with
a kubeconfig may point back here and serve the request itself, so it
is left alone, unless it serves no CommitRequests: then the request is
NotAllowed, and the message says to create it on that cluster.
- The author comes from the request's own audit fact on the route of that
KubeProvider, awaited with the attribution grace whenever attribution
is on. The reconciler acquires the fact stream of commitrequests on the
route, which it never did. A request no fact names, on a provider that
has received audit facts, is AuthorUnresolved and saves nothing.
- The owner claims a request by writing its first status, status.author
and Ready=Unknown (Saving), before it attaches. Every status write is
conditional on the version it was decided from; after the claim a
conflict re-applies the worker's outcome and never restarts the save.
- A GitTarget that does not exist is GitTargetNotFound once attachTimeout
has passed, written only into an empty status.
spec.window.attachTimeout defaults to 5s, since the request now waits
for its author as its edits do. Steps of different requests run four at
a time, so one request's author wait does not hold up the others.
BREAKING CHANGE: a CommitRequest's author is found from its audit event,
reported in status.author; in progress it is Ready=Unknown rather than
Ready=False; spec.window.attachTimeout defaults to 5s.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ough the shared core
A CommitRequest can be created on the cluster a GitTarget mirrors, next
to the edits it saves. The source.configbutler.ai group and its
RemoteSaveRequest are gone: CommitRequestServer watches the
CommitRequests of every KubeProvider whose new spec.commitRequests is
Reconcile or ReconcileAndDeleteFinished, through that provider's
identity, and hands each one to the same core as the control-cluster
reconciler, so attach: Next, whenNothingToCommit: CommitEmpty, the phase
reasons and the metric reach it too.
- The GitTarget's KubeProvider alone picks the path that serves a
request, so two providers watching one cluster no longer race to refuse
each other's requests. A request on a source cluster must name its
GitTarget's namespace, or it is not picked up.
- GitTarget.spec.allowedCommitRequests grants set exactly one of
consumerNamespaces (the control cluster) and sourceNamespaces (the
cluster the GitTarget mirrors, bounded by what the KubeProvider lends
it). allowedRemoteSaveRequests and requestSelector are gone.
- spec.commitRequests defaults to Ignore, and takes only Ignore beside
inCluster. Only ReconcileAndDeleteFinished stamps delete-after and
deletes finished requests on the source cluster.
- A provider watches only the namespaces it lends its GitTargets, one
watch across the cluster when a grant lends "*". The KubeProvider
reports it in status.commitRequests.namespaces and the
CommitRequestsServed condition (Watching, NothingToWatch,
CRDNotInstalled, VersionNotServed, Forbidden, Unreachable), outside
Ready, shown at priority 1 as Saves.
- The default watch policy excludes configbutler.ai/commitrequests.
- The CommitRequest CRD carries its schema revision as the last line of
the kind's description, guarded by a hash test, and ships on its own as
the release asset commitrequest-crd.yaml.

…ager only for attribution
The chart renders its self-signed Issuer only when it mints a
certificate: the audit ingress certificates with attribution, or the
metrics certificate with metrics TLS. The default install renders no
cert-manager object, so it needs no cert-manager, and the quickstart
moves the cert-manager step under named commit authors.
The CommitRequest design spec, the status conditions guide, the
architecture, security model, components, definitions and chart README
describe one kind, picked up on the control cluster or on a source
cluster and served by one core, with its author from audit and no
admission webhook. The attribution guide asks the audit policy to keep
covering commitrequests creates. UPGRADING records what changed since
0.54.0, and commitrequest-crd.yaml is listed among the release assets.

… cluster's client
A namespace whose list was denied stayed reported Forbidden until its
next watch ended, up to five minutes after the Role was granted: a list
that succeeds now clears it. A watcher whose cluster client could not be
built gave up for good while reporting Watching: it now retries, and
reports the cluster Unreachable until it can.

A CommitRequest is registered with the branch worker once its own audit
event named its author, no longer at creation, and its edit is
attributed the same way. On the e2e GitTargets, whose windows close on
the first silence, an edit made right after the request could reach the
worker first and commit alone: the Flux applier's catch-up save ended
NoWindow. The two specs that save before they edit wait for the claim,
Ready=Unknown, and configuration.md and UPGRADING say so.

… and keep retention to the owner
- A source cluster's watcher restarts when its KubeProvider's credential
version changes, and builds its client fresh from that credential rather
than taking the shared cached one, so its watches and status writes move
to the rotated kubeconfig together.
- Whether a provider has received audit facts is read after the author
wait, not from the provider fetched before it: facts that arrive during
the wait refuse a request whose own fact is still missing.
- Only the path that owns a finished request, or refused it because no
path serves its GitTarget, follows its apply and deletes it. Another path
that deletes finished requests leaves it alone whatever delete-after it
carries; once the GitTarget is gone, any deleting path may.

feat!: one CommitRequest for the control cluster and source clusters, the applier's catch-up after saves, and late applier writes kept in the apply window (#456)
BREAKING CHANGE: the admission webhook is removed: drop the --admission-webhook, --admission-webhook-bind-address and --admission-webhook-cert-* flags and the chart's servers.admission values. A CommitRequest's author comes from its own audit event and is reported in status.author; the AuthorAttributed condition is gone, and a request no audit event names, on a cluster that sends them, ends AuthorUnresolved. A CommitRequest in progress is Ready=Unknown rather than Ready=False, spec.window.attachTimeout defaults to 5s, and a CommitRequest on the control cluster for a GitTarget that mirrors another cluster is refused NotAllowed. The chart renders its cert-manager Issuer only when it mints a certificate. See docs/UPGRADING.md, "The admission webhook is gone; a CommitRequest's author comes from audit".
END_COMMIT_OVERRIDE
Stacked on #455. Four of the gitops-api asks (
docs/future/gitops-api-open-asks.md): #35, thekube-root-ca.crtvote, #34 (an e2e for their production topology), and saving from a source cluster, which #34's review led to. The #34 e2e found a bug in the apply window, fixed here. This branch also carries four review fixes to #455's generator write-back (below).Saving went through two designs on this branch. The final one is in
docs/review/20261027-save-request-simplification.md: oneCommitRequestkind, served on the control cluster and on a source cluster through one core, with no admission webhook. It replaces theSaveRequest/RemoteSaveRequestpair and the window takeover the earlier commits built.One
CommitRequest, two ways in, one coreCommitRequestkeeps its name and group from 0.54.0. It is now the one operator kind that can also live on a source cluster, next to the edits it saves.CommitRequestReconcilerpicks it up with the operator's own client.CommitRequestServerwatches theCommitRequests of everyKubeProviderwhose newspec.commitRequestsisReconcileorReconcileAndDeleteFinished, through that provider's credential.Both hand each step to
commitRequestCore(internal/controller/commitrequest_core.go), which decides everything else once: admission, the author, the attach and its outcome, the applycatchUp: AfterPushasked for, and retention. Soattach: Next,whenNothingToCommit: CommitEmpty, the phase reasons andcommit_requests_totalreach source-cluster requests too, and a fix is made once.Which path serves a request. The named
GitTarget'sKubeProvideralone picks the owner: the control-cluster path for aninClusterprovider, that provider's watch for a kubeconfig. Three rules keep several observers of one request safe:GitTargetNotFound, onceattachTimeouthas passed with noGitTarget, and only into an empty status.status.author,Ready=Unknown, reasonSaving) before it attaches. If the claim conflicts and an outcome is already there, it stops without saving. After the claim, a conflict re-applies the worker's outcome and never restarts the save. Ownership is structural, so after a restart the owner resumes its own claim.This also fixes a race in the earlier source-side server, where two providers watching one cluster could each refuse the other's request. A control-cluster request for a
GitTargetthat mirrors another cluster isNotAllowedwhen that provider serves noCommitRequests, and left to the provider's watch when it does (its kubeconfig may point back here). A request on a source cluster must name theGitTarget's namespace, or it is not picked up.The author comes from audit, on both paths. The core looks the request's own audit fact up in the same index as the edits', on the route of the
GitTarget'sKubeProvider, keyed by the uid and resourceVersion it was created with, within--author-attribution-grace. The control-cluster path now acquires the fact stream ofcommitrequests, which it never did. The wait runs whenever attribution is on. A request no fact names, on a provider that has received audit facts, isAuthorUnresolvedand saves nothing; on one that has not, it names nobody and saves the unnamed window.spec.window.attachTimeoutdefaults to5s, as the request now waits for its own audit event as its edits do.Admission.
GitTarget.spec.allowedCommitRequestsgrants set exactly one ofconsumerNamespaces(control-cluster namespaces,from: Same|Names|Selector|All) andsourceNamespaces(names or"*"on the mirrored cluster, never one theKubeProviderdoes not lend theGitTarget), enforced in CEL. Omitted, the list is[{consumerNamespaces: {from: Same}}], with an API-server default, noomitempty, a Go mirror andTestGrantDefaultsMatchCRDs, so a single-cluster user writes what they did in 0.54.0. TheGitTargetthat admitted a request is recorded instatus.gitTargetUID; a replacement must admit it again.The source-cluster side.

IgnorebesideinCluster. A provider watches only the namespaces it lends (one watch across the cluster when a grant lends"*"), so a namespace-scoped credential is enough. It reports what it watches instatus.commitRequests.namespacesand in a newCommitRequestsServedcondition, outsideReadyand removed onIgnore:Watching,NothingToWatch,CRDNotInstalled,VersionNotServed,Forbidden,Unreachable, each message with its fix, atpriority=1asSaves. GitOps Reverser never writes the CRD. It ships on its own as the release assetcommitrequest-crd.yaml, and carries its schema revision as the last line of the kind's description ("Schema revision 1, compatible from revision 1."), guarded by a hash test that fails when the CRD changes without a revision bump. The default watch policy excludesconfigbutler.ai/commitrequests.Retention keeps 0.54.0's
delete-aftercontract on both paths: always on the control cluster, on a source cluster only withReconcileAndDeleteFinished.The admission webhook is gone
The default install paid for the
validate-operator-typeswebhook and got nothing for saves: without Redis its command-author store was nil. It goes completely, with/validate-all(an always-allow e2e endpoint matching every write), the Redis command-author store, the--admission-webhook*flags, the chart'sservers.admissionvalues, itsCertificateandValidatingWebhookConfiguration,config/webhook, anddocs/spec/commitrequest-admission-authorship.md. TheWatchRulefeedback it gave stays where it was enforced: the writer refuses the configuration, and theGitTargetreportsMultipleSourceNamespaces. Takeover (spec.window.author,unattributedWindows, theSaved-ByandAuthor-Sourcetrailers) goes with it, because only admission could name a taker.cert-manager only for a certificate. The chart renders its self-signed
Issueronly when it mints a certificate: the audit ingress certificates with attribution, or the metrics certificate with metrics TLS. The default install needs no cert-manager, and the quickstart moves that step under named commit authors.spec.catchUpAfteronFluxClaimandArgoCDClaim(#35)A push of GitOps Reverser's own asks no apply, because the flush already put its edits on the cluster. Since 0.54.0 that left the applier's own state behind the branch until somebody else pushed: a
Kustomization'sstatus.lastAppliedRevision, itsGitRepository's artifact, and anything that reads them (Flux commit-status notifications, gitops-api's publish of what was applied).spec.catchUpAfter, a converge (CatchUp) becomes pending for it. The clock starts on the first pass that finds the applier behind, and again on every send. A burst of saves costs one apply, and an applier already at the tip costs nothing. The interval is when the apply is asked for, not a deadline: the converge then waits for the barrier, a backoff and the flush like any other reason.0salso drops a converge that only the interval left pending. A converge something else asked for, such as a save's, stays.FluxClaimdefaults to1m.ArgoCDClaimdefaults to0s(off): a sync runs hooks, and Argo CD's refresh already compares the live state against the tip.ApplyRequest.Currentstops holding once a live edit is mirrored after the send, and the converge waits a fresh interval.ForeignCommit,Repair,Refusaland the startup converge are unchanged, so continuous editing still cannot starve them (S1).CommitRequest.spec.catchUpAsDefinedOnClaim(the default) leaves the apply to the claim'scatchUpAfter.AfterPushmakes a converge pending for theGitTarget's applier right after the save's commit is pushed; it does not yield to an edit.

A source-cluster scenario runs gitops-api's production setup: a

Once the CRD is in the workspace and the provider setsReconcileAndDeleteFinished, theKubeProviderreportsCommitRequestsServed=True, a request in the workspace is refused until theGitTargetgrants its namespace insourceNamespaces, and thenCommittedwith its message, stamped for deletion, andApplied=True.CommittedandApplied=True.The apply window waits for the watch
An apply window judged a write by when its event reached the branch worker, and closed 10s after the operation completed. On a source cluster that sends no audit facts each event waits the whole attribution grace, so the applier's writes arrived after the window closed, and a revert of an edit was mirrored as an edit. Now, once an operation completes, its window takes a barrier: the newest resourceVersion of every stream's collection, which each stream answers once it handled an event or bookmark at or past it. The window stays open for its grace and until every stream answered, for at most two minutes.

task lintandtask testpass (unit coverage 82.5%); locally the only lint failures come from an uncommitted WIP doc that is not part of this branch. The design doc's acceptance tests are ininternal/controller/commitrequest_core_test.goandcommitrequest_server_test.go: overlapping observers of one cluster (the namespace omitted and set), two kubeconfig providers on one source cluster, both race orders of aGitTargetcreated during the attach wait, a conflict after the outcome, a restart whileSaving, a delayed audit fact, retention on both paths,attach: NextandCommitEmptyon the source path, the CRD discovery reasons, and the server end to end over a fake source cluster. The main e2e suite asserts that a control-cluster save's author comes from audit and authored its commit. Locally, the main e2e suite ran 111 specs with one failure, the Flux applier's catch-up save, which endedNoWindow: a request is now registered only once its own audit event names its author, so on a GitTarget whose windows close on the first silence its edit could commit first. The two specs that save before they edit now wait for the claim (Ready=Unknown), as configuration.md and UPGRADING now say, and the flux-applier and commit-request specs pass on the fix (11 of 11). The source-cluster and bi-directional corners run in CI.🤖 Generated with Claude Code
