The readiness-gate Job's argocd.argoproj.io/sync-options annotation used Replace=true alone, which maps to kubectl replace. That fails against a live Job on any upgrade that changes the Job spec (e.g. an image tag bump), because spec.selector and spec.template.metadata.labels are server-generated and immutable, and the rendered manifest correctly omits them. The Application is left permanently OutOfSync while still showing Healthy. Add Force=true so ArgoCD deletes and recreates the Job when a replace fails, instead of a Helm-style sync hook: hook-annotated resources are excluded from ArgoCD's normal drift detection, so an image-tag-only bump could silently go undetected. Verified against a real ArgoCD control plane in a Kind cluster: the unpatched Replace=true annotation reproduces the exact sync failure from the issue on an image-tag bump, and Replace=true,Force=true resolves it (Job deleted and recreated with the new image, Application reports Synced).

📋 Multi-persona review — Approve
Method: 3 parallel persona reviewers (Correctness/ArgoCD · Test-coverage · Architecture/Docs) → an adversarial senior meta-reviewer that independently re-derived every claim from the resolved code and rendered goldens.
Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick
Overall
Tight, well-reasoned two-part fix for the readiness-gate Job stuck permanently OutOfSync under ArgoCD (#2367), and unusually well-tested. The crux reproduces independently: Job-level Replace=true,Force=true handles genuine spec diffs (immutable spec.selector/pod-template labels make plain kubectl replace fail; Force is ArgoCD's documented delete-recreate fallback), while Application-level ApplyOutOfSyncOnly=true — scoped to only the -readiness folder's Application — excludes the in-sync Job from the apply set so Force never fires on a no-op resync. That closes exactly the "recreate on every sync" loop CodeRabbit flagged.
Verified and not flagged: waveForFolder refactor is behavior-preserving; fresh-cluster first sync still runs the gate (absent Job = OutOfSync = included); RBAC in the same Application still self-heals on genuine drift without dragging the Job along; both deployer paths (native template + argocd-helm map round-trip) emit the option scoped correctly, pinned by byte-exact goldens; Flux/Helmfile correctly left untouched (ArgoCD-specific root cause).
Findings (all 🔵 — none block)
- 🔵 F1 — see the inline comment on
application.yaml.tmpl: the "scoped to the Application only" comment could note it also governs the folder's RBAC (intended). Highest-value optional tweak. - 🔵 F3 (optional, not inline — the anchor line isn't in this diff) —
pkg/bundler/deployer/argocd/argocd_test.goTestGenerate_LevelBasedSyncWaves(~L1928) already builds a realistic multi-component bundle (cert-manager + nfd + gpu-operator, each gated) but asserts only sync waves. A one-lineContainscheck per component (only*-readinessApplications carry the option) would be belt-and-suspenders. Low value —isReadinessFolderis folder-local and exhaustively unit-tested, and the single-component golden already pins primary-vs-readiness separation. Fine to skip. - 🔵 N1 (cosmetic, no action) — the argocd-helm
map[string]anyround-trip strips comments, so the Helm-rendered bundle shows a bare- ApplyOutOfSyncOnly=truewith no rationale. Uniform with the pre-existingServerSideApply=true(also comment-less after round-trip) — an accepted, consistent limitation, not a regression.
Confirmed non-issues (examined, dismissed)
- Named constants for sync-option tokens — dismissed. CLAUDE.md's anti-pattern targets resource names shared between Go and templates, not ArgoCD keyword tokens;
ServerSideApply=true/CreateNamespace=trueare already inlined in both template andargocdhelm.go, so a constant would diverge from precedent. - ArgoCD-version sensitivity — informational; the PR body already records the ArgoCD v3.5.1 empirical verification.
- Residual caveat (not a defect): an explicit operator
argocd app sync --forcestill delete-recreates the Job — a deliberate action outside the drift loop this PR targets.

🔵 Nitpick — Comment could note the option governs the whole readiness Application (RBAC included)
The comment reads "scoped to the readiness-gate Application only," which is accurate at the bundle level. Within this Application the option also governs the gate's RBAC (ServiceAccount / ClusterRole / ClusterRoleBinding) — which is intended and benign: RBAC still self-heals on genuine drift, while the in-sync Job is no longer dragged along and recreated.
Blast radius: None — doc precision only. Same wording is mirrored in pkg/bundler/gatemanifest/manifest.go.
Fix: Add half a sentence (here and in the mirrored gatemanifest comment) clarifying it applies to every resource in the readiness Application, RBAC included, and that this is intended — so a future reader doesn't assume it's Job-scoped.

Summary
Force ArgoCD to replace the readiness-gate Job on upgrade, without deleting/recreating it on every no-op sync.
Motivation / Context
The readiness-gate Job's
spec.selector/spec.template.metadata.labelsare server-generated and immutable, so a plainReplace=truesync-option (kubectl replace) is rejected by the API server on any spec change (e.g. an image tag bump), leaving the Application permanentlyOutOfSyncwhile still showingHealthy.Fixes: #2367

Two-part fix, added in two commits:
argocd.argoproj.io/sync-options: Replace=true,Force=trueon the readiness-gate Job's own annotations.Force=trueis ArgoCD's documented delete-and-recreate fallback when a replace fails on immutable fields. Deliberately not a Helm-style sync hook — those are excluded from ArgoCD's normal drift detection, which would let an image-tag-only bump go undetected.Force=truealone causes ArgoCD to delete-and-recreate the Job on every sync, not just genuine spec diffs, needlessly rerunning readiness checks. Empirically confirmed (real ArgoCD v3.5.1 on kind) thatApplyOutOfSyncOnlyonly works as anApplication-levelspec.syncPolicy.syncOptionssetting — as a per-resource annotation token it's silently accepted but has zero effect. AddedApplicationData.ApplyOutOfSyncOnly, scoped to just the-readinessfolder's Application (not applied globally) via a sharedisReadinessFolderhelper, rendered conditionally inapplication.yaml.tmpl.Any operator who has already deployed a pre-fix bundle should expect one additional
