Conversation
…d shrink the source-scope surface The layout question had grown to eight documents across `spec/`, `design/` and `future/`, so following the argument meant knowing which folder each step lived in. `docs/layout/` now holds it: two current-behavior contracts, one design page, and the worked examples. Everything else stays where it was. **The model reverses its own earlier thesis and leads with the reversal.** #319 shipped the ancestor walk, which made registration an invariant and retired three of the five arguments against path templates. So the template stays, and what it cannot express becomes two optional booleans on the existing `spec.placement`: - `useKustomize` — create and maintain the folder's `kustomization.yaml`. Registering a new file with a root that already governs it is an invariant, not a setting; the flag's one job is what to do when there is no root. Its `true` half is the only genuinely new machinery here, and it is what makes an empty repository bootstrappable. - `serializeNamespace` — whether the document carries `metadata.namespace`. A `*bool`, because no plain default preserves today's behavior: `false` breaks a flat folder, `true` writes a redundant line into every kustomize folder that already supplies one. Unset means infer, which is not a guess — the existing inference omits the namespace only when the governing kustomization sets it to this resource's own namespace, so an explicit `false` is an override of a correctness rule and gets a post-scan guard. The two pair up: with `useKustomize: true` the operator owns the root it writes `namespace:` into, which is what makes both the omission provable and the created kustomization meaningful rather than an empty file. `spec.layout`, `kind`, `scope`, `kustomize.create`, the LayoutProfile question, the migration and four maintainer-review findings are deleted with it. Nothing in the placement work is breaking, so none of it waits for a coordinated consumer bump. **Source scope.** Declines Flux-style impersonation and deletes `GitTarget.spec.allowedSourceNamespaces` with its selector machinery (4,569 lines, and the only cross-cluster read in the authorization path), on an API reading rather than a security one: the chain from a Git folder back to the object that fills it never leaves one namespace. Keeps `allowedNamespaces`, renamed `accessFrom`, reversing an earlier draft. Redefines `sourceNamespace: "*"` as one cluster-wide list and watch. Also raises F9's envtest to Tier 1 — the only queue item whose answer is unknown rather than whose work is unscheduled — and prices staying on `v1alpha3` as a one-consumer countdown rather than a constant. The Go changes are comment-only: doc-path citations following the move. `task lint` and `task test` pass; e2e is unaffected because no executable line changed.

📝 WalkthroughWalkthroughThe change reorganizes layout documentation, replaces the earlier layout-model proposal with template-based placement fields, revises API planning documents, adds six layout examples, records source-scope decisions, and updates code and documentation references. No functional code changes were made. ChangesLayout documentation and placement model
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The PR does not ship runtime behavior, but several examples and cross-document references are internally inconsistent: bootstrap targets point to unavailable GitProviders, one namespace example contradicts root-generation semantics, and some copyable snippets use stale API names or omit explicit workload hardening. These issues could mislead implementation or produce unusable or less-secure copied manifests, so merge should wait for documentation corrections or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

…y why a folder-wide claim is ordinary `spec.placement` means "where a NEW document goes"; everything already written is match-first and never moves, which is what makes a template safe to change. `serializeNamespace` does not have that property, and the write path already proves it: plan_flush.go strips metadata.namespace from a new document using the placement result and from an UPDATE using the document's own observed namespace source, and a document whose namespace is inherited is located in the file bytes by a namespace-less identity. A field that rewrites existing documents as they are next touched, and decides how they are found, does not belong inside a struct documented as new-files-only. So it is `spec.serializeNamespace`. `useKustomize` stays in `spec.placement`, because it passes the same test: it decides whether a new file's directory has a root to join, and creates one when there is none. Group by blast radius, not by topic. Also answers whether a folder-wide namespace claim is a strange thing to state. It is not: "no document carries its namespace" is the portable-artifact convention behind every kustomize base, Flux's targetNamespace, Argo's destination.namespace and a chart's .Release.Namespace, while "every document carries it" is the convention for a folder applied directly. Cluster-scoped resources are exempt, and the one genuinely non-uniform shape — a tree of nested roots, each supplying its own namespace — is what the unset default already handles per document. The uniform claim is what an explicit setting is for; the non-uniform folder is what unset is for. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

declared-path-in-a-subdirectory item from its Tier 1 listing, keeping the
table’s SHIPPED status as the sole status for that item.
In `@docs/design/placement-visibility-and-declared-defaults.md`:
- Around line 254-258: Remove stale layout API names from the examples: in
docs/design/placement-visibility-and-declared-defaults.md lines 254-258, rename
every YAML status.layout key to status.placement; in
docs/future/direction-and-configuration-surface.md lines 139-142, update
Examples 2 and 3 to remove spec.mode, spec.layout.kind, and status.layout, or
clearly mark those examples as historical.
In `@docs/design/source-scope-simplification.md`:
- Around line 219-224: The migration documentation must classify
allowAnySourceNamespace as a semantic change rather than a pure rename,
reflecting the changed false behavior with existing allowedSourceNamespaces

the related sourceNamespace "*" entry to describe the precise rollout impact,
including that wildcard access depends on the target policy and

- Around line 183-185: Resolve the namespace contradiction in the placement
example: either configure the example so useKustomize and serializeNamespace
accurately produce an environment-agnostic artifact, or update the documented
root-generation model and add an expected-output example showing the resulting
namespace behavior. Ensure the shop subscription and artifact path semantics are
consistent with the chosen approach.
In `@docs/layout/examples/brownfield-kustomize/expected-cache.patch`:

rather than declaring Tree or MultiNamespace, and the ClusterWatchRule as
selecting the ClusterRole.

Document these as semantic changes, not a pure rename.
The migration table calls allowAnySourceNamespace a same-semantics rename, but the earlier section states that false changes behavior when an existing allowedSourceNamespaces policy excluded the rule's own namespace. It also says that old * without a target policy already reached every namespace visible to the credential, while api/v1alpha3/watchrule_types.go says that no target policy denies *. Align the migration text with both existing contracts and describe the rollout impact precisely.

Keep the status example aligned with the scenario scope.
This scenario states that no file is placed and the placement ladder does not run. The status message instead says "render root '.' governs new files", which makes the example look like a new-file placement case. Describe the existing-file write path instead.

config/gittarget.yaml does not name media or monitoring, and it does not declare Tree or MultiNamespace. The WatchRule names the source namespaces. The target resolves to the documented layout and scope. Update this paragraph to match the revised API.

Jellyfin official Docker image 10.10.7 non-root USER 1000 allowPrivilegeEscalation Kubernetes
💡 Result:
The official Jellyfin Docker image (including version 10.10.7) supports running as a non-root user [1]. While the image does not enforce a specific UID/GID by default (running as root if no user is specified), you can safely run it as a non-root user (e.g., UID 1000) by configuring the security context in your Kubernetes deployment or the user directive in Docker [1][2][3]. In Kubernetes, you can enforce this by using the podSecurityContext or container securityContext [2][4][3]. To run Jellyfin as a non-root user with UID 1000 and disable privilege escalation, you should configure your manifest as follows: securityContext: allowPrivilegeEscalation: false runAsNonRoot: true runAsUser: 1000 runAsGroup: 1000 fsGroup: 1000 When running as a non-root user, ensure that the volumes mounted to /config and /cache are owned by the corresponding UID (1000) on the host, or use fsGroup to allow the pod to access these volumes [2][3]. Note that if your deployment requires specific hardware access (like GPUs), you may need to add the appropriate group to the supplementalGroups list in your security context to ensure the non-root user has permission to access the device nodes [2][3]. Disabling allowPrivilegeEscalation is a recommended security best practice and is fully supported by the Jellyfin container [2][4][3][5].

Security Misconfiguration (CWE-250)
Exploitability: Moderate
Run Jellyfin without root privileges.
If this example is applied to a cluster, set allowPrivilegeEscalation: false, runAsNonRoot: true, runAsUser: 1000, and runAsGroup: 1000. The image defaults to root, so runAsNonRoot: true alone is insufficient.

…s not enough Answers whether the layout situations under discussion can hurt us, by measuring rather than reasoning. Two shapes exist where the manifest store's view of a document's namespace and the namespace kustomize renders it into can disagree, and neither is refused when the folder is read: - a document carrying metadata.namespace: beta inside a folder whose kustomization sets namespace: alpha. An explicit namespace is authoritative as written and the transformer is never consulted, so the store indexes beta with NO diagnostic while the folder renders alpha. - a parent root and its child root that both assign. kustomize is deterministic here (the parent transformer runs last and wins); we decline to guess, so the document is namespace-less, unmatchable by identity, and placement treats the live object as new. Both are caught, and nothing reaches the worktree: the first refuses with "does not render to the live object after the write", and the second gets as far as proposing a second file before kustomize's own ID conflict fails the build — neither the file nor the resources: entry survives. So the render check at the write path is the backstop for this whole class, and it holds. Nothing pinned that until now: a change that relaxed the check would have turned a refusal into a silent write with no test failing. Adds the read-side halves to the contextual-namespace corpus, which docs/layout/contextual-namespace.md says is meant to grow one folder per "can we support X?" question, plus the multi-namespace tree that was missing from it — a parent assigning nothing and each child root carrying its own namespace, which is the shape the model leaves to inference rather than to a flag. The remaining gap is legibility, not safety: both failures surface as an opaque render error rather than as the one fixable thing that is wrong, which is what the post-scan validation pass is for.

Replaces #318, #323 and #324, which are closed. One PR, 90 files, and the design it lands is materially smaller than the one those carried.
The layout model
The earlier thesis wanted
spec.placementreplaced by aspec.layoutdiscriminated union. #319 shipped the ancestor walk, which made registration an invariant and retired three of that thesis's five arguments. So the template stays and gains two optional booleans:useKustomizesays this folder is a kustomize folder and the operator maintains its root. Registering a new file with a root that already governs it happens either way — that is the invariant #319 shipped, and re-opening it would re-create #295 — so the flag's one job is what to do when there is no root: create one atspec.path, withnamespace:when the folder is single-namespace. That is the only genuinely new machinery in the proposal, and it is what makes an empty repository bootstrappable.serializeNamespacesays whether the committed document carriesmetadata.namespace. It is a*boolrather than a plain one because no plain default preserves today's behavior: defaultingfalsebreaks a flat folder, whose documents must carry their own namespace; defaultingtruewrites a redundant line into every kustomize folder that already supplies one. Unset means infer — and infer is not a guess:placement.goomits the namespace only when the governing kustomization sets it to this resource's own namespace. An explicitfalseis therefore an override of a correctness rule, which is why it gets a post-scan guard and unset does not.The two pair up in
empty-repo-bootstrap: withuseKustomize: truethe operator owns the root it writesnamespace:into, which is what makes the omission provable and the created kustomization meaningful rather than an empty file.Deleted with the reversal:
spec.layout,kind,scope,kustomize.create, theLayoutProfilequestion, the migration, and four maintainer-review findings. None of the placement work is breaking, so none of it waits for a coordinated consumer bump.Four kustomize facts are measured against v5.8.1 rather than recalled; three contradict assumptions the earlier model was built on.
Source scope
Declines Flux-style service-account impersonation — it buys several identities behind one credential against one source cluster. Deletes
GitTarget.spec.allowedSourceNamespacesand its selector machinery (4,569 lines, and the only cross-cluster read in the authorization path) on an API reading rather than a security one: the chain from a Git folder back to the object that fills it never leaves one namespace, so ordinary RBAC onwatchrulesalready answers it. KeepsallowedNamespaces(renamedaccessFrom), reversing an earlier draft — source RBAC bounds what a credential may read, never which tenant may wield it. RedefinessourceNamespace: "*"as one cluster-wide list and watch, and names what is lost: source-side label selectors.Also
docs/layout/holds the layout question in one place: two current-behavior contracts, one design page, and six worked examples. The API wave and the placement-visibility page stay indesign/, where they belong.v1alpha3is priced as a one-consumer countdown rather than a constant: each wave leaves a refused field in the schema, so the number of remaining waves is finite.docs/INDEX.mdgets smaller than it is onmaindespite adding documents — its rows were 2,500-character abstracts and are hooks now.Validation
