# Documentation Structure README Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Replace the starter `docs/README.md` with the normative documentation structure, placement rules, source-of-truth policy, and Obsidian-compatible navigation conventions approved for Mosaic Stack.

**Architecture:** Keep `docs/README.md` as the root documentation atlas and authoring contract. Use audience books for current user, administrator, and developer content; keep API contracts and operational artifacts in dedicated directories; retain `_old_structure/` as a read-only migration quarantine. Do not move or rewrite existing documentation in this slice.

**Tech Stack:** Markdown, YAML front matter examples, Obsidian wikilinks, relative Markdown links, Prettier.

---

### Task 1: Write the documentation structure contract

**Files:**

- Modify: `docs/README.md`
- Reference: `docs/plans/2026-08-10-docs-information-architecture-design.md`

**Step 1: Confirm the approved design and current transition constraints**

Verify that the README preserves these decisions:

- `docs/mosaic-stack/` is not a target content directory.
- `docs/README.md` is the documentation atlas and placement contract.
- Existing files are not moved or rewritten yet.
- `_old_structure/` is read-only migration quarantine.
- Root control files, audience books, API, reports, tasks, plans, scratchpads, releases, archive, and assets have distinct responsibilities.

**Step 2: Replace the starter README**

Write `docs/README.md` with these sections:

1. Purpose and scope.
2. Reader entry points.
3. Complete target directory tree, including the optional `.obsidian/` vault configuration boundary and the workflow-only `plans/` directory.
4. Root control document responsibilities.
5. Guide book responsibilities and chapter rules.
6. Artifact directory responsibilities.
7. Placement matrix for agents.
8. Source-of-truth and precedence rules.
9. Page naming and front matter conventions.
10. Obsidian wikilink and Git-hosted Markdown link conventions.
11. Authoring workflow for new or changed documentation.
12. Migration rules for `_old_structure/`, legacy root files, and repository references.
13. Current transitional exceptions and explicit non-goals.

Use future target paths as a blueprint, but clearly label directories that are not populated yet so readers do not mistake the blueprint for completed migration.

**Step 3: Preserve the existing Obsidian configuration boundary**

Document `.obsidian/` as optional vault metadata only. Do not place Markdown content, scratchpads, reports, or source-of-truth files under it, and do not modify its existing files in this task.

**Step 4: Keep the README portable**

Use ordinary relative Markdown links for indexes and Git-hosted navigation. Use Obsidian wikilinks for graph-oriented relationships such as `Related`, `Depends on`, and `Referenced by`. Do not make a current navigation path depend solely on a Git-host-incompatible wikilink.

**Step 5: Review the resulting document**

Check that an agent can answer all of these without inspecting another file:

- Where does a user guide go?
- Where does an admin runbook go?
- Where does architecture or an RFC go?
- Where does an API contract go?
- Where does an active scratchpad go?
- Where does a review or QA report go?
- Where does an approved design or implementation plan go?
- Which files are normative, working notes, evidence, or historical?
- What may be added directly under `docs/`?

**Step 6: Commit only the README**

Because `docs/GETTING_STARTED.md` is an unrelated pre-staged deletion, stage and commit only `docs/README.md`:

```bash
git add docs/README.md
git commit --only docs/README.md -m "docs: codify documentation structure"
```

Expected: the commit contains only the README change; the existing staged deletion and orchestrator state remain outside the commit.

### Task 2: Verify the README-only change

**Files:**

- Verify: `docs/README.md`

**Step 1: Run Markdown formatting validation**

Run:

```bash
pnpm exec prettier --check docs/README.md
```

Expected: Prettier reports the file is formatted.

**Step 2: Run whitespace validation**

Run:

```bash
git diff --check HEAD^ -- docs/README.md
```

Expected: no whitespace errors.

**Step 3: Validate required structural anchors**

Run a focused search or script confirming the README names:

- `PRD.md`, `TASKS.md`, and `SITEMAP.md`;
- `USER-GUIDE/`, `ADMIN-GUIDE/`, `DEVELOPER-GUIDE/`, and `API/`;
- `reports/`, `tasks/`, `plans/`, `scratchpads/`, `releases/`, `archive/`, and `assets/`;
- `_old_structure/` as read-only quarantine;
- `docs/mosaic-stack/` as retired/non-authoring;
- Obsidian wikilinks and Git-compatible Markdown links.

Expected: all anchors are present and no section instructs agents to create content under `docs/mosaic-stack/`.

**Step 4: Confirm scope isolation**

Run:

```bash
git status --short
git show --stat --oneline HEAD
```

Expected: the new commit contains only `docs/README.md`; pre-existing `.mosaic/orchestrator/*`, `docs/GETTING_STARTED.md`, and `docs/.obsidian/` states remain untouched.

**Step 5: Record verification evidence**

Update the task scratchpad at `docs/scratchpads/DOCS-IA-001.md` with commands, results, known transitional gaps, and the next migration slice. Do not modify active `docs/TASKS.md`; its single-writer policy belongs to the orchestrator.
