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. It now lives in docs/layout/, the one topic folder, with every entry labelled with the lifecycle class it would have had.

The reversal

The model reverses its own earlier thesis and leads with it. #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 the two things a path cannot express become additive members of the existing spec.placement:

spec:
  placement:
    byType: {...}                 # unchanged, as shipped
    serializeNamespace: Auto      # Auto | Always | Never
    kustomizeRoot: Adopt          # Adopt | Create | Require

spec.layout, kind, scope, kustomize.create, the LayoutProfile question and the migration are all deleted. The largest breaking change in the queue is no longer a breaking change.

The two fields nest inside spec.placement rather than sitting beside it — free only before they exist, and it keeps the placement axis one member of the spec rather than three. api-wave.md turns "the folder is described on the GitTarget, the connection describes only the connection" into a struct boundary rather than a sentence in a document, and prices staying on v1alpha3 as a one-consumer countdown rather than a constant.

Four kustomize facts are measured against v5.8.1 rather than recalled; three of them contradict assumptions the earlier model was built on.

What else is here

  • Six worked examples: repository folder, matching configuration, one live input, and the exact patch proposed. implementation-plan.md turns them into an executable corpus whose remaining skips are the definition of done.
  • F9's envtest raised to Tier 1 in the open-asks queue: the only item whose answer is unknown rather than whose work is unscheduled, and it gates planning the enum work.
  • Go changes are comment-only — doc-path citations following the move.

Validation

task lint, task test (coverage 77.4%, baseline held) and task lint-docs pass. task test-e2e was not run: no executable line changed.

Stacked

docs-source-scope-and-crd-handling builds on this branch and will be retargeted to main once this merges.

…model onto two additive fields

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. It now lives in `docs/layout/`, the one topic folder, with every entry
labelled with the lifecycle class it would have had. `docs/INDEX.md` says why
that exception exists.

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
the two things a path cannot express become additive members of the existing
`spec.placement`: `serializeNamespace` (Auto|Always|Never) and `kustomizeRoot`
(Adopt|Create|Require), both defaulting to today's behavior. `spec.layout`,
`kind`, `scope`, `kustomize.create`, the LayoutProfile question and the
migration are all deleted. The largest breaking change in the queue is no
longer a breaking change.

They nest inside `spec.placement` rather than sitting beside it, which is free
only before they exist. `api-wave.md` makes the "the folder is described on the
GitTarget, the connection describes only the connection" principle a struct
boundary rather than a sentence in a document, and prices staying on v1alpha3
as a one-consumer countdown rather than a constant.

Six worked examples make the proposal tangible — repository folder, matching
configuration, one live input, and the exact patch proposed — and
`implementation-plan.md` turns them into an executable corpus whose remaining
skips are the definition of done. F9's envtest is raised to Tier 1 in the
open-asks queue: it is the only item whose answer is unknown rather than whose
work is unscheduled, and it gates planning the enum work.

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.

Review Change Stack

📝 Walkthrough

Walkthrough

The change reorganizes placement documentation under docs/layout/, replaces the earlier breaking layout proposal with an additive placement model, adds six worked examples, updates planning documents, and retargets code and documentation references.

Changes

Placement documentation

Layer / File(s) Summary
Placement model and implementation plan
docs/layout/model.md, docs/layout/api-wave.md, docs/layout/implementation-plan.md, docs/layout/new-file-placement-rules.md, docs/layout/placement-visibility-and-declared-defaults.md
Documents the additive serializeNamespace and kustomizeRoot fields, status.placement, API sequencing, validation work, and template rules.
Layout example corpus
docs/layout/examples/*
Adds six scenarios with GitTarget and watch configuration, repository fixtures, live-object inputs, expected patches, and scenario contracts.
Documentation index and roadmap updates
docs/INDEX.md, docs/TODO.md, docs/design/*, docs/future/*, docs/spec/*, docs/design/support-boundary/*
Reorganizes document indexes, updates placement sequencing, records repository ownership boundaries, and revises related configuration guidance.
Source and test reference updates
api/v1alpha3/gittarget_types.go, internal/**, test/e2e/new_file_placement_e2e_test.go
Updates comments and documentation links to the new docs/layout/ paths without changing code behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e89cb

This PR consolidates and revises the layout contract, but the current documentation still publishes conflicting API/status names and obsolete model references, while worked examples contain configuration and path mismatches that prevent them from producing their documented results. A security-sensitive example also omits container hardening defaults. These are bounded repository-local issues, but the PR is not merge-ready until the published contract and examples are corrected or explicitly accepted.

Inline comments:
In `@docs/design/open-asks-priority.md`:
- Line 241: Reconcile the roadmap status for the declared-path placement item by
updating either the SHIPPED marker near the placement table or the “none
shipped” statement in the later placement summary so both sections consistently
reflect whether this item shipped in 0.42.1.

In `@docs/future/direction-and-configuration-surface.md`:
- Around line 142-150: Update the document’s validation text, Example 1, and
closing explanation to remove the obsolete spec.layout, kind, scope, and
layout.kustomize.create API references, and use the current spec.placement
fields defined in docs/layout/model.md. Apply the same replacement to the
additionally affected sections, or clearly mark the document as historical
instead of presenting the obsolete model as active.

In `@docs/layout/api-wave.md`:
- Line 63: Update the documentation around GitProvider commit fields so it
consistently identifies the current shape as GitProvider.spec.push.commitWindow
and GitProvider.spec.push.commit.message before using it as the basis for
GitTarget.spec.commit; remove or revise the conflicting claim that
GitProvider.spec.commit already exists.

In `@docs/layout/examples/brownfield-kustomize/expected-cache.patch`:
- Around line 1-8: Move the brownfield-kustomize fixture files from repository/
into repository/apps/demo/ to match the configured target path and the patch
target; update all corresponding README links to the new locations while
preserving the fixture contents.

In `@docs/layout/examples/brownfield-kustomize/README.md`:
- Line 54: In the sentence containing “the existing root,” change the verb
“reach” to “reaches” to correct the subject-verb agreement.

In `@docs/layout/examples/empty-repo-bootstrap/README.md`:
- Around line 50-52: Update the documentation sentence describing the
single-namespace behavior to acknowledge that config/gittarget.yaml declares
spec.placement, and instead state that no path-template selection is declared or
configured. Preserve the surrounding explanation about files being placed beside
the root and the resulting namespace collision.

In `@docs/layout/examples/homelab-argocd/input/paperless.yaml`:
- Line 3: Update the comment in the paperless fixture to reference the existing
expected-paperless.patch filename instead of
expected-application-paperless.patch; leave the fixture content unchanged.

In `@docs/layout/examples/README.md`:
- Around line 18-20: Update the availability statement in the README’s config
description to reflect that spec.suspend already exists and is used by the
fixtures and adoption guidance. Keep serializeNamespace and kustomizeRoot
identified as proposed fields, and ensure the wording remains consistent with
the examples and API proposal.

In `@docs/layout/examples/tree-multi-namespace/config/gittarget.yaml`:
- Around line 14-19: Update the target configuration containing kustomizeRoot:
Adopt to declare media and monitoring in spec.allowedSourceNamespaces, and
enable allowSourceNamespaceOverride: true so watchrule.yaml can request those
namespaces instead of homelab-config. Preserve the existing placement behavior
and comments.

In `@docs/layout/examples/tree-multi-namespace/README.md`:
- Around line 20-22: Update the README’s references to the removed
Tree/MultiNamespace layout terminology, including the target configuration and
folder descriptions, to use placement and the canonical identity path shown in
config/gittarget.yaml; ensure all affected statements consistently describe the
current configuration model.

In
`@docs/layout/examples/tree-multi-namespace/repository/media/apps/deployments/jellyfin.yaml`:
- Around line 15-17: Update the jellyfin container definition to add a
securityContext with allowPrivilegeEscalation set to false. Keep the existing
image and container configuration unchanged.
- Around line 15-17: Update the Jellyfin container security context to set
runAsNonRoot true and use an approved non-root UID and GID; ensure the mounted
and required filesystem paths have permissions allowing that identity to operate
successfully.

In `@docs/layout/implementation-plan.md`:
- Around line 177-178: Clarify the PR 3 validation scope in the implementation
plan: limit its table and fixtures to the two rules available before
serializeNamespace and kustomizeRoot are introduced, and move or explicitly
defer those enum-dependent checks to PR 4. Ensure the documented sequence
includes validation for both fields once PR 4 adds them.
- Around line 64-67: Update the scenario-shape documentation to include the
third status-only case: a kustomizeRoot: Require declaration without a root,
alongside the existing Never-without-supplier and ambiguous-folder cases. State
that it uses expected-status.yaml and compare the post-scan observation rather
than asserting a patch, keeping the corpus contract consistent.

In `@docs/layout/new-file-placement-rules.md`:
- Around line 934-938: Resolve the contradiction between the placement rules in
this section and the encrypted-sibling guidance around the placement ladder:
either remove the stale encrypted-sibling inference rule if inference is
unsupported, or explicitly define it as an exception by adding it to the ladder
and updating the related examples consistently.
- Line 19: Update the visible labels of the retargeted links in the
related-links list, including the links around
gittarget-repository-validity-and-placement.md, so they use
new-file-placement-rules.md or explicitly identify the old names as historical
while preserving their existing targets.

Apply the same fix in `@docs/spec/sops-single-file-no-multidoc.md` at line 8: The
link target is current, but the visible label names a removed file.

In `@docs/layout/placement-visibility-and-declared-defaults.md`:
- Around line 254-259: The placement status contract in this document is
inconsistent: replace remaining status.layout references in the heading, table,
and YAML examples with status.placement, then reconcile the documented fields
and shape with the conditions and status.placement definitions in
implementation-plan.md before publishing.

- **`scope: SingleNamespace` requires `layout.namespace`, plus an exact matching one-name
`allowedSourceNamespaces.names` list.** The question "which namespace is the single one?"
must not be answered by the rules: N rules do not own the folder, and the first-writer-wins
alternative is exactly the silent re-deciding the layout model exists to forbid. The identity
therefore lives on the GitTarget as a structural layout field, while the authorization bound
stays an authorization bound. A selector cannot guarantee singularity, and CEL can check the
equality at admission. Rules then merely subscribe within it: an omitted `sourceNamespace`, an
explicit match, or `"*"` all resolve to that one namespace, and a rule naming any other namespace
refuses loudly under the existing bilateral check.

Replace the obsolete spec.layout model in this document.

The revised proposal removes spec.layout, kind, scope, and kustomize.create and adds fields under spec.placement. These lines still define layout.namespace and layout.kustomize.create as the active API shape. Update the validation text, Example 1, and closing explanation to use the fields in docs/layout/model.md, or mark this document as historical.

Align the fixture with the configured target path.

config/gittarget.yaml sets path: apps/demo, and expected-cache.patch correctly targets that path. The fixture files are instead directly under repository/, so the patch cannot apply. Move them under repository/apps/demo/ and update the README links.

The Kustomize root supplies the omitted namespace, so the new document still represents
`demo/cache`. The first write has a home that the existing root reaches.

seed commit, and compare with `expected-*.patch`. For a scenario carrying `expected-status.yaml`
instead of a patch, compare the observation the post-scan pass produced with that file — two scenario
shapes need this and neither can assert a patch: a `Never` declaration with no supplier, and an
ambiguous folder covering two roots.

Include the third status-only scenario.

This section lists only serializeNamespace: Never without a supplier and an ambiguous folder. Lines 164-175 and 241-244 also require a kustomizeRoot: Require scenario without a root. Add that scenario here, or document its separate assertion format. Keep the corpus contract consistent.

The pass is written in PR 3 against the two rules that exist today; PR 4 adds the third row when it
adds the field. That ordering is deliberate: the machinery is proven before a new field depends on it.

Make the PR 3 validation scope explicit.

serializeNamespace: Never and kustomizeRoot: Require are introduced in PR 4 at Lines 180-191. The table at Lines 168-172 lists checks for both fields as PR 3 work. Identify the two rules that PR 3 can implement, or move the enum-dependent checks and fixtures to PR 4. Otherwise the sequence can omit a required validation.

Use current filenames in relocated-document link labels.

These links resolve to new-file-placement-rules.md, but their visible labels still advertise removed filenames. Rename the labels or explicitly mark them historical so readers are not directed to stale document names.

`{kindLower}` — the lower-cased kind, so `ConfigMap` becomes `configmap` — is **decided and not yet
built**. It is a variable rather than a `toLower` function because a function invites an expression
language into a field that is deliberately not one. It is what a user writes to ask for the
`configmap-cache.yaml` convention that the built-in rungs do not produce: the kustomize root names a
new sibling `{name}.yaml` and never infers a naming convention from the folder's existing files.

Resolve the placement ladder contradiction.

This text says built-in rungs never infer naming conventions from existing files. Lines 1033-1035 still say placement may follow encrypted siblings, while docs/layout/model.md defines no inference rung. State whether encrypted-sibling inference remains an exception. If not, remove the stale rule. If yes, add it to the ladder and examples.

Align the published status contract.

This paragraph declares status.placement, but the same file still uses status.layout in its heading, table, and YAML examples. It also says placement is an observation, while docs/layout/implementation-plan.md Lines 127-143 defines conditions and a different status.placement shape. Replace the old field name and reconcile the fields before publishing this API proposal. Otherwise readers can implement incompatible status schemas.

Superseded by #325, which folds this work into a single PR on a smaller design: the two placement enums became two optional booleans (useKustomize, serializeNamespace), and the CRD-handling material is dropped for now.
