PR 1 of 6, splitting #318 into pieces that can be reviewed one at a time. This one is the mechanical move; nothing in it is a decision.

Five documents move into docs/layout/, organized by topic:

From To Class
docs/spec/gittarget-new-file-placement-rules.md docs/layout/new-file-placement-rules.md spec
docs/spec/contextual-namespace-and-kustomize-folder-editing.md docs/layout/contextual-namespace.md spec
docs/design/gittarget-layout-model.md docs/layout/model.md design
docs/design/gittarget-api-wave.md docs/layout/api-wave.md design
docs/design/placement-visibility-and-declared-defaults.md docs/layout/placement-visibility-and-declared-defaults.md design

Topic-organized is a deliberate exception to INDEX.md's rule that folders are picked by lifecycle, so docs/layout/README.md labels each page with the class it would have had. Two are spec-class and cited by path from Go source; the rest are intent.

How to review this

git log --follow works and the diff is rename-detected, so the only content to read is:

  • docs/layout/README.md — new, ~40 lines.
  • docs/INDEX.md — the five entries gather into one "layout topic" section.
  • 9 Go files — comment path updates only, no behavior. task lint-docs checks these citations, so doccheck proving green is the verification that the move is complete.

What follows

PRs 2-6 land the new material on top: the worked examples (two PRs), the implementation plan, the maintainer review, and the source-scope proposal. Each is independently mergeable, and the order is forced by doccheck — a document cannot land before what it links to. docs/layout/README.md grows a row per PR.

#318 stays open until they are all up, so its review feedback stays reachable.

Validation

task lint (doccheck: 206 markdown files, every reference resolves), task vet, task test (77.3%, within tolerance) all pass. The Go changes are comment-only; this exact comment text passed a full task test-e2e on #318's branch.

Summary by CodeRabbit

  • Documentation
    • Added a dedicated layout documentation section organized by topic.
    • Consolidated layout guidance and clarified document categories and relationships.
    • Updated cross-references throughout the documentation to reflect renamed and relocated pages.
    • Corrected links for file placement, contextual namespaces, API planning, and layout models.
  • Bug Fixes
    • Fixed broken documentation links in guides, specifications, comments, and references.

The question of where a live object's document goes in Git, and what else has to
change so that file is reachable, had grown to five documents split across
docs/spec/ and docs/design/. Following the argument meant knowing which of the two
a given piece lived in, which is a filing decision leaking into the reading.

They move to docs/layout/, organized by topic. That is a deliberate exception to
INDEX.md's rule that folders are picked by lifecycle, so the folder's README
labels each page with the class it would have had — two are spec-class and cited
by path from Go source, the rest are design-class intent. The names lose the
prefixes the old folders needed to disambiguate them: gittarget-layout-model.md
becomes model.md, contextual-namespace-and-kustomize-folder-editing.md becomes
contextual-namespace.md.

No content changes. Every reference moves with the files, including the ones in
Go comments that task lint-docs checks, so doccheck proves the move rather than a
reader having to.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds docs/layout/ as a topic-based documentation folder. It moves layout references to current paths across documentation and updates related Go comments and test comments. No functional code changes are included.

Changes

Documentation layout relocation

Layer / File(s) Summary
Define the layout topic
docs/INDEX.md, docs/layout/README.md
The index and new README describe layout/ as a topic-based folder and classify its documents.
Correct layout document links
docs/layout/*
Layout documents now use current filenames and relative paths.
Update repository documentation references
docs/TODO.md, docs/architecture.md, docs/design/..., docs/future/..., docs/spec/...
Existing documentation now links to the relocated layout documents.
Update Go and test citations
api/v1alpha3/gittarget_types.go, internal/..., test/e2e/...
Source and test comments now cite the current layout documentation paths.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 9b8cf

The move preserves runtime behavior, but some documentation links still display removed filenames and the layout topic is described with conflicting document counts. The PR is mergeable with explicit owner awareness and follow-up to make navigation and scope descriptions consistent.

A second exception, and this one is about topic rather than lifecycle. [`layout/`](layout/README.md)
collects the whole layout question, which had grown to eight documents across three folders, so
following the argument meant knowing which folder each step lived in. It mixes lifecycle classes
on purpose and labels every entry with the class it would have had, which its
[README](layout/README.md) does. It is the only topic folder, and adding a second one should take
the same amount of argument this one did.

Define one scope for the layout topic.

The supplied files use two incompatible scopes: docs/INDEX.md says eight documents across three folders, while docs/layout/README.md says five documents in spec/ and design/. Because docs/INDEX.md also says layout/ collects the whole question, either make both counts match or list the three additional documents.

  • docs/INDEX.md#L29-L34: correct the eight-document claim or add links to the missing documents.
  • docs/layout/README.md#L3-L7: align the five-document description with the final topic scope.

Update visible labels for relocated documents.

The links resolve under docs/layout/, but several rendered labels still advertise filenames that no longer exist. Replace each stale filename label with the current basename or a stable document title so readers are not directed toward removed paths.

Not splitting this after all — the docs stay in one PR (#318). The split added process without addressing the actual concern.
