…eign commits Wishlist ask #29 from the gitops-api team: every commit the reverser pushes wakes Flux, which can then apply that commit over a cluster that has already moved past it, so the branch ping-pongs. The ask is to have the reverser forward a reconcile trigger only for commits it did not author, and only after any pending writes have been replayed on top. Imported as written, with the filename typo fixed, markdownlint's emphasis style applied, and the links to gitops-api's own docs made absolute. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…on triggers The ask filters the reconciler's webhook so our own pushes stop waking it. That is not enough: Argo CD's timed refresh resolves the tip, and with selfHeal off a new revision still auto-syncs, so every push of ours is applied two to three minutes later over whatever is still pending. Flux applies on every reconcile, whatever woke it. So the reconcilers keep fetching, rendering and applying, but apply only when we ask: Argo CD without automated sync and a sync pinned to the checked revision, Flux through its Receiver with long intervals. The response also records where the ask's rule needs correcting (empty refusal commits, the replayed push, per-cluster suppression), the branch-worker state that replaces per-delivery classification, and what changes for gitops-api and in this repository. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
… code Docs-first, for review: the guides now read as they will once GitOps Reverser decides when Flux or Argo CD applies a folder. - A GitTarget names its applier (spec.applier: kustomizationRef, applicationRef or webhook). Requests go out only on a quiet branch, for a foreign commit, an eligible refusal, or, for Flux, a CatchUp that keeps its artifact current after our own pushes. - Argo CD runs with automated.enabled: false, and our sync copies the operation its automated sync would build, pinned to the checked commit. - GitProvider.spec.receiver takes the Git host's push webhook on its own listener; a delivery is a hint judged against the ref advertisement. - onRefusal: PushEmptyCommit becomes onRefusal: Reapply. - definitions.md gains applier, apply request, quiet branch and receiver. The push-notification design drops its options menu for the decided design, and the reply to gitops-api's ask is aligned with it. The generated settings table is untouched until the CRDs change.

Resolve the historical GitGuardian occurrence.
GitGuardian reports a Generic Password in commit e27d3e862bcadd5ea22867bdb90f105c93696d59, while scanning nine PR commits. The reviewed-head Password value comes from readGitCredentialSecretDataBase64(), so changing that field will not clear the reported historical occurrence.
The incident details are required to choose the correction. If GitGuardian confirms a false positive, resolve the occurrence through its supported false-positive workflow. Otherwise, remove or rotate the actual credential and rewrite the offending commit history. Do not assume that renaming the local variable or changing the reviewed head clears the check.

Hand back targets that fail initial resolution.
A transient GitTarget read error exits resolve before a job exists. The dispatcher therefore cannot retry or hand back that target. The worker has already consumed its foreign, refusal, or catch-up debt, and an unchanged remote observation creates no new debt. The apply request can remain lost.

Resolve the GitGuardian finding on commit b6c49e7.
The GitGuardian check fails on this PR. It reports a "Generic Password" in commit b6c49e7dc6d8cf8f536bab31b5371059dd372ffc, at line 201 of this file. At the reviewed head, line 201 holds no secret. Password comes from readGitCredentialSecretDataBase64() at runtime, and the ggignore markers are already in place. Because the finding is in commit history, a change to the head does not clear the check.

Source: Pipeline failures
A GitTarget can now name the Flux Kustomization that applies its folder (spec.applier.kustomizationRef). The branch worker then decides when it applies: only on a quiet branch, with no open commit window and no pending writes, so an apply never reverts an edit that is live and not yet pushed. It asks for three reasons: - ForeignCommit: the branch gained a commit this worker did not push. Open windows are closed and pending writes replayed onto it first, so Flux applies a commit that already carries the API side's answer. - Refusal: a refused edit on a target with spec.onRefusal: Reapply. - CatchUp: after this worker's own pushes, once the branch has been quiet for spec.applier.quietPeriod (30s), so Flux's artifact never falls behind and its own timers and restarts apply values the cluster already holds. A request stamps reconcile.fluxcd.io/requestedAt on the GitRepository, or on the Kustomization when the artifact already holds the commit, as `flux reconcile --with-source` does. It is delivered off the worker's queue by a dispatcher in internal/applier, retried, superseded by newer requests, recorded as an ApplyRequested Event and in status.applier. The ApplierConfigured condition checks the Kustomization in the source cluster. GitProvider.spec.receiver accepts the Git host's push webhook (github, gitlab, gitea, generic-hmac) on a new --receiver-bind-address listener and publishes status.webhookPath. A delivery is a hint: the worker reads the advertisement and judges from the remote whether the branch moved. BREAKING CHANGE: spec.onRefusal PushEmptyCommit is replaced by Reapply, which requires spec.applier and asks that one Kustomization to reapply instead of moving the branch with an empty commit. A stored PushEmptyCommit reads as Ignore. See docs/UPGRADING.md. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…d prove the revert was requested The seeded root commit has no parent to diff against and reads as empty, so the spec now compares against the count before the GitTarget exists. It also asserts the GitTarget's ApplyRequested Event names Refusal, so the revert is shown to come from GitOps Reverser's request rather than Flux's own schedule. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…rite The bi-directional e2e reproduced the race the trigger exists to prevent. A window with a zero idle timeout opened, closed, committed and pushed inside one wake that ended quiet, so the quiet period was inherited from the quiet wakes before it and the catch-up went out at once. Flux applied that commit over the next API edit, and the revert was mirrored as Flux's commit. Deciding a write now restarts the quiet period wherever in the wake it happens, so a catch-up waits quietPeriod from the last write.

What comes after the Flux applier: the Argo CD applier and how to build it, the PushEmptyCommit regression for appliers GitOps Reverser cannot name, the smaller loose ends, and the parts of the trigger the tests do not reach yet. The index entry for the trigger design now describes it as built for Flux. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A delivery waits on the worker's queue behind an in-flight push rather than being compared against a recorded in-flight commit; the foreign-commit test compares against the last observed tip; a Flux request stamps the GitRepository or the Kustomization, not both; the SourceMismatch example uses the real message; and the receiver's Helm default is empty.

Record the 2026-10-16 review's six findings and their shared cause (a request decided once is never checked again at the patch), the fix for each, and the hand-back that replaces giving up on a failed request. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The worker decided a request once, and the dispatcher attempted it for up to four minutes against whatever the cluster, the GitTarget and the branch had become. Every attempt now reads each GitTarget again and keeps only those that still name the applier on this branch and that their ClusterProvider admits; a Refusal needs consent at the attempt, and a target that withdrew it is asked a CatchUp. Flux.Request checks the GitRepository's repository and branch before it stamps anything. A request that cannot be delivered is retried for about one quiet period, then handed back to the branch worker, which owes it again and sends it on a quiet branch with its own backoff. A refusal owed while the branch was busy is checked for consent again before it is sent, and a collection that recovers cancels its own obligation. The applier check runs under a deadline, and the chart's Flux role drops list and watch. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A Refusal asks one applier, but a GitRepository that has to fetch the tip wakes every Kustomization that reads it; say so in the five places that promised no other folder is woken. Document the per-attempt checks and the hand-back, the dropped outcome, the upgrade order the old CRD allows, and the access-review permission.

The ledger behind status.applier was keyed by namespace and name and never pruned, so a GitTarget deleted and recreated under the same name inherited its predecessor's last request. It now remembers the uid it recorded for, and the GitTarget controller forgets an entry when the object is gone. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A Kustomization whose GitRepository follows another branch is reported SourceMismatch, a ForeignCommit for it never stamps that source, and the request is delivered once the source is fixed. A real Gitea push webhook to the operator's receiver Service makes Flux apply a Git-side push with nothing else on the branch. A unit test covers a second write inside the quiet period. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
With no receiver and no API edit, an idle GitTarget's steady-tick refresh finds an outside push, and Flux applies it from a ForeignCommit request: a missing webhook costs latency, never an apply. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
docs/flux.md is the complete Flux setup: why the GitRepository must not fetch on its own, a worked example, the rules ApplierConfigured checks, permissions, the Git host's webhook, what a request does and that it is asynchronous, how to check it works, troubleshooting, and which test proves each claim. A unit test reads the guide's complete example and checks it against the applier: the objects decode with no unknown field, ApplierConfigured comes out True, a request stamps the GitRepository, and the Flux objects follow the page's own advice. The bi-directional guide's Flux section now points to it, and the chart's applierAccess comment matches the role. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The second review found every remaining problem in the hand-off between the worker's decisions and the dispatcher's retries: a retry skipped the quiet check, outlived a refusal that had recovered, ran for a recreated GitTarget, or waited on another applier's branch-wide backoff. The dispatcher now carries out one attempt and reports back. It keeps no queue, never retries, and never asks for something weaker than it was told: when no GitTarget still holds the request's reason it asks nothing. The worker keeps what each applier is owed, one attempt out at a time, with the applier's own backoff, and decides every retry on a quiet branch at the tip as it is then, giving back a refusal only while it still stands. Requests carry each GitTarget's uid, and an obligation owed to an incarnation that is gone is dropped. The three relations get their own units: the branch (repository and branch, shared across workers of different GitProviders) owns quietness, the applier owns obligations and retries, the GitTarget owns consent. A shared Kustomization is asked once and waits for the longest quiet period of the GitTargets naming it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The bi-directional corner proved that a new GitRepository revision alone makes a Kustomization apply by pushing an empty commit. It now pushes a commit that changes only a file outside the applied folder, which proves the same property without the trick. Code and test comments cite the new apply trigger design, or the archived one for the Git-side reference. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
docs/design/apply-trigger.md replaces the trigger design (now archived in docs/finished/) with why GitOps Reverser decides when Git is applied, what building it taught, the three units that make the 1:n cases work, the apply window that is still racy and how to shrink it, and the aim beyond Flux. The follow-ups page and gitops-api's original ask are removed. architecture.md and configuration.md state the aim again (Argo CD with a pinned sync and no catch-up, a webhook applier) beside what is built, and describe the worker-owned obligations. The refusal empty commit is gone from the design docs. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An attempt decided at one commit could land after the worker pushed a newer one and, finding the artifact at the older commit, stamp the Kustomization, re-applying it over a published edit. A request now carries a check the dispatcher makes just before it stamps: the commit is still the branch tip and nothing is waiting to be published, on this worker or a sibling. When it fails nothing is stamped (Stale), and the worker decides again at the next quiet moment, with no backoff. A ForeignCommit whose artifact already holds the commit stamps nothing: that artifact already woke the Kustomization. Only a Refusal stamps the Kustomization, to revert drift at an unchanged commit. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A push notice that reached a busy branch always closed the open window, so the Git host's late webhook for the worker's own push cut the next save's window, splitting that save across two commits. A notice naming the tip already observed now leaves the window alone; anything else still closes it. The delivery's after is still never trusted as the tip, and leaving a window open is the safe direction: it closes on its timers, and its push finds any move by the compare-and-swap. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
GitHub's default content type for a webhook wraps the JSON in a payload field, so a hook left on that default got a 400 on every push, while a Flux Receiver accepts it. The signature is over the raw body, so the payload is unwrapped only after verification. The flag help no longer promises an elected replica: leader election is not switched on, and the chart runs one. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Document that only a Refusal stamps a Kustomization whose artifact holds the commit, that a stale decision stamps nothing, and the stale outcome. The apply trigger design gains its roadmap, with the customer review's remaining items: the applier in the GitTarget's own cluster, receiver hardening, closing the apply window's loop, Argo CD, the webhook applier, and more than one replica. The Flux guide notes that a namespace Role is enough. The e2e recovery assertion checks that Flux reaches the tip, since whether the retry or Flux's own fetch gets there first is a race.

The refusal-reapply and flux-applier specs each carried a copy of the helper that creates a GitRepository and Kustomization; they now share one, which takes the branch and reads the in-cluster Gitea test credential straight into the template's fields. The Reapply row of the configuration reference says the request asks and the applier's status says whether the revert happened. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

… alike The route was /git-push/<namespace>/<name> and answered 401 or 503 for a GitProvider that exists and 404 for one that does not, so anybody who could reach the listener could list namespaces and providers. It is now the hex HMAC-SHA256 of "<namespace>/<name>" keyed by the receiver token, published in status.webhookPath and found through a cache index, so an unknown path costs no API read. The receiver recomputes the path from the token it reads, so a rotated token retires the old path at once. An unknown path, a path from before a rotation, a missing token and a wrong signature all answer the same 404. At most 8 deliveries are handled at once (429 above that, before anything is read), and the body cap before verification drops from 25 MiB to 2 MiB.

spec.applier.clusterProviderRef names the ClusterProvider whose cluster holds the Kustomization; omitted, it is the GitTarget's own spec.clusterProviderRef, so nothing that exists changes meaning. It covers Flux run from a management cluster (gitops-api's kcp workspaces, every hub-and-spoke install), which used to sit at ApplierNotFound forever, and it is the shape the Argo CD applier will take for a hub Argo CD. The applier's provider is gated exactly as a source's is: its accessFrom must admit the GitTarget's namespace (authz.ApplierAdmitted), checked by ApplierConfigured and again by the dispatcher before every attempt. A ClusterProvider change re-checks the GitTargets using it as an applier's. An applier-only cluster has no cluster context, because nothing would release one: ApplierDynamicClient reuses a mirrored cluster's client, and otherwise builds one per call from the provider as it resolves.

An apply runs a few seconds after its stamp. An API edit in those seconds,
to a field the Kustomization applies, was reverted by the apply and mirrored
as Flux's commit, so the edit survived only in history. For an object both
sides changed the API value wins; this applies that rule to the apply
window.
The window is now known: the dispatcher reports a delivered attempt only
once Flux finished it (lastHandledReconcileAt carries the stamp, or the
Kustomization attempted a new revision after a source stamp), at most 5
minutes, and the worker keeps it open 10 seconds more for the watch.
Inside it, a write whose latest managedFields entry is kustomize-controller
alone, to an object in the applier's folders that the API side edited after
the attempt was sent, is withheld. Git keeps the edit and the CatchUp its
push owes applies it back. Only proof withholds: a same-second tie with
another manager could be the edit itself and is mirrored as before, and a
DELETE never is. Every collision is logged and counted in
apply_window_collisions_total{outcome="withheld"|"ambiguous"}.

…e standard GitOps Reverser takes full control of when Argo CD syncs: an Application a GitTarget names has automated sync off, and every sync is one GitOps Reverser asked for, pinned to a commit it checked. The plan records the upstream facts it rests on (argocd-controller is the field manager for client-side and server-side apply alike, the operation autosync builds, never replacing a running operation, sync windows apply to every operation), what to build, the tests, and three open questions: where prune comes from, the operation's initiator, and hooks on every foreign commit. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Prune from automated.prune when the block is kept with enabled: false, the initiator Automated: true as gitops-reverser, and hooks on every foreign commit shipped as they are. Built on #419's branch. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
spec.applier gains applicationRef beside kustomizationRef, exactly one of the two (CEL). quietPeriod times the CatchUp, and Argo CD is never asked to catch up, so it is rejected with an applicationRef; it loses its schema default for that reason, and an omitted one still means 30s. The branch worker keys an applier by its kind as well as its cluster, namespace and name. An Application is never owed a CatchUp: with automated sync off it applies nothing on its own, so nothing it holds goes stale. ForeignCommit and Refusal reach it as they reach a Kustomization. The apply window knows each kind's own field managers: kustomize-controller for Flux, argocd-controller and argocd-application-controller for Argo CD.

… checked
The Argo CD client sets the Application's operation to the sync automated
sync would start (source, prune from syncPolicy.automated, syncOptions and
retry from syncPolicy), with the revision pinned to the commit and
initiatedBy {username: gitops-reverser, automated: true}. It is an update of
the whole Application, as Argo CD's SetAppOperation makes it, guarded by the
resourceVersion read, and it clears status.operationState. An operation
already running is waited out (up to the apply window) and never replaced;
an update that lost a race reads again and decides again.
Two places differ from what was planned, each read from Argo CD's source: a
failed operation awaiting its retry is Running with a finishedAt, so a sync
counts as finished only once its phase is Succeeded, Failed or Error; and a
retry with refresh: true drops the pinned revision, so the copied retry
omits it. The request's token travels in operation.info.
The dispatcher picks Flux or Argo CD by the applier's kind behind one Client
(Validate, Request, Handled), so an attempt and its wait for the applier are
unchanged; apply_requests_total counts applier_kind="application".

…ent it ApplierConfigured checks the applier by its kind: an Application must exist, sync this repository and branch from a single source (targetRevision the branch name or refs/heads/<branch>), have automated sync off, and be updatable. Automated sync on is the new AutomatedSyncEnabled reason, which stalls the GitTarget like the other configuration errors. RBAC: config/rbac/argocd-applier-role.yaml and the chart's applierAccess.argocd grant get and update on argoproj.io applications, off by default in the chart, beside the Flux grant. docs/argocd.md is the Argo CD guide, with the standard spelled out (automated sync off; refresh and Argo CD's webhook may stay) and its complete example held to the code by argocd_guide_test.go. The configuration reference, the bi-directional guide, the support boundary, the metrics guide and UPGRADING describe the Application applier, and apply-trigger.md takes what lasts of the implementation plan, which is deleted.

…c off The Argo CD specs now run the standard: the Application has automated sync off and is named by spec.applier.applicationRef, and its GitProvider has a receiver Gitea pushes to. They prove that a Git-side push is synced by a ForeignCommit request pinned to that commit (and Argo CD's bookkeeping still makes no commit); that two quick API edits keep the later value with no further commit and no sync; that a refused edit with onRefusal: Reapply is reverted by an Argo CD sync; and that an Application with automated sync on is AutomatedSyncEnabled, stalls its GitTarget, and is never synced by GitOps Reverser. The phases that characterized automated sync (selfHeal losing an edit, ignoreDifferences, selfHeal: false with Argo CD's webhook) are gone with it. Argo CD's webhook stays wired, and is shown only to refresh. The receiver wiring is shared with the Flux applier spec. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The Argo CD guide gains a requirements table (Argo CD 3.1 for automated.enabled, a single Git source on the branch, a recursive or kustomize source, annotation tracking, update RBAC, the receiver) and a "What not to do" section, each item read from Argo CD's source: manual, CI and rollback syncs; sync windows, which keep a blocked sync Running and run it later, still pinned to a commit that may be older than the tip; watching the kinds hooks create, which BeforeHookCreation deletes and recreates on every sync; switching automated sync back on; ApplicationSet-generated Applications; selfHeal and ignoreDifferences; Replace=true; and retry refresh. It also corrects the troubleshooting row that called a window-blocked sync "skipped". Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
GitOps Reverser now decides when Flux or Argo CD applies a folder. In a bi-directional setup every commit the reverser pushed used to wake the applier, which then applied that commit to a cluster that had already moved on: two API edits a few seconds apart were enough to have the first commit applied over the second edit, mirrored back as the applier's commit. Filtering webhooks is not enough, because Flux's timers and restarts and Argo CD's automated sync apply on their own too. So the reverser owns the trigger, and the applier keeps doing the fetching, rendering, applying and pruning. The design is
docs/design/apply-trigger.md; the user guides aredocs/flux.mdanddocs/argocd.md.What changes
GitTarget.spec.appliernames exactly one applier: a FluxKustomization(kustomizationRef) or an Argo CDApplication(applicationRef).
