# Phase 08 Plan 02: MkDocs Infrastructure Setup Summary

**One-liner:** MkDocs build pipeline installed with mkdocs-shadcn theme, replace Jekyll _config.yml with mkdocs.yml at project root, nav_order stripped from all 13 public docs pages.

## What Was Built

Migrated the documentation build infrastructure from Jekyll + Just the Docs to MkDocs + mkdocs-shadcn. The existing Jekyll `docs/_config.yml` is deleted and replaced by `mkdocs.yml` at the project root. All 13 public docs pages had their Jekyll-specific `nav_order:` front matter stripped; navigation order is now controlled exclusively by the `nav:` block in `mkdocs.yml`. The `docs/plans/` directory is excluded from the built site via `exclude_docs`. `mkdocs build --strict` passes with zero warnings.

## Tasks Completed

| Task | Name | Commit | Files |
|------|------|--------|-------|
| 1 | Add mkdocs dev dependencies | c53fa88 | pyproject.toml, uv.lock |
| 2 | Create mkdocs.yml, delete _config.yml, strip nav_order | c5e63bf | mkdocs.yml, .gitignore, docs/_config.yml, 13x docs/*.md |

## Decisions Made

1. **mkdocs.yml at project root** — placed at project root per MkDocs convention with `docs_dir: docs` pointing to existing docs directory
2. **site/ gitignored** — MkDocs build output added to .gitignore (generated artifact, should not be tracked)
3. **nav_order: stripped from all 13 files** — Jekyll-specific front matter removed; `title:` preserved for `<title>` tag and breadcrumbs in MkDocs

## Verification Results

- `uv run mkdocs build --strict` exits 0 with no warnings
- `test -f mkdocs.yml` passes
- `test ! -f docs/_config.yml` passes
- `grep -r "nav_order" docs/*.md` returns no matches
- `test ! -d site/plans` passes (plans/ excluded from built site)
- `grep "name: shadcn" mkdocs.yml` matches
- `grep "exclude_docs" mkdocs.yml` matches
- `grep "plans/" mkdocs.yml` matches

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 2 - Missing Critical Config] Added site/ to .gitignore**
- **Found during:** Task 2
- **Issue:** `mkdocs build` creates a `site/` directory (build artifact) that was not gitignored, leaving it as an untracked directory
- **Fix:** Added `site/` entry to .gitignore in the same Task 2 commit
- **Files modified:** .gitignore
- **Commit:** c5e63bf

## Self-Check: PASSED

- mkdocs.yml: FOUND
- 08-02-SUMMARY.md: FOUND
- Commit c53fa88 (Task 1): FOUND
- Commit c5e63bf (Task 2): FOUND
- `mkdocs build --strict` exits 0: CONFIRMED
- `grep -r "nav_order" docs/*.md` returns no matches: CONFIRMED
- `test ! -d site/plans` passes: CONFIRMED
