`pnpm docs:dev` failed with two distinct symptoms after #159 forced
vite past its vulnerable 5.x line:

1. VitePress refused to boot with `VitePress v1 is not compatible
   with rolldown-vite. Use VitePress v2 instead.` The previous
   override `vite@<6.4.2 → >=6.4.2` had no upper bound; pnpm
   resolved vitepress's `vite ^5.0.0` constraint up to vite 7.3.2,
   which uses the new rolldown bundler and is explicitly rejected
   by VitePress 1.x.

2. Even when the server eventually booted on a different port, the
   console was flooded with `Failed to resolve dependency: dayjs,
   debug, @braintree/sanitize-url, cytoscape, cytoscape-cose-bilkent`
   — the vitepress-plugin-mermaid wrapper injects those into
   `optimizeDeps.include` but they aren't reachable from the
   workspace root under pnpm's strict isolation (transitives of
   mermaid, never hoisted).

Three changes:

* `pnpm.overrides.vite` is now an **unconditional** `>=6.4.2 <7`
  range (not the previous `<6.4.2 → >=6.4.2` selector). The
  selector form was a no-op once vite had already resolved into
  7.x; the unconditional form forces a downgrade to 6.4.2 across
  every consumer (vitepress, @nx/vite, @analogjs, Vitest). All
  six top-level projects still lint, test, and build.

* `optimizeDeps.include` simplified to `['mermaid']`. Vite 6's
  dep optimizer walks Mermaid's transitives automatically once
  Mermaid itself is included, so the explicit list of children
  the previous fix carried (#157) becomes redundant.

* `dayjs`, `debug`, `@braintree/sanitize-url`, `cytoscape`,
  `cytoscape-cose-bilkent` are pinned as **top-level devDeps**.
  The vitepress-plugin-mermaid wrapper expects them at the
  workspace root; under pnpm's strict isolation a transitive of
  mermaid isn't reachable from a `optimizeDeps.include` lookup
  unless the workspace declares it. Pinning silences the
  resolution warnings without changing the resolved tree (these
  packages were already present via mermaid).

Verification: `pnpm docs:dev` boots clean on :5173, home + ADR
pages return 200, no warnings. `pnpm docs:build` succeeds in ~9 s.
`pnpm audit --audit-level=moderate` reports zero vulnerabilities.
`pnpm exec nx run-many -t lint test build` for the 6 main projects
all pass.

julien d94df427a1 fix(docs): pre-bundle mermaid deps so the dev server resolves dayjs/cytoscape (#157)
CI / check (push) Successful in 1m6s
CI / commits (push) Has been skipped
CI / scan (push) Failing after 1m15s

## Summary

`pnpm docs:dev` rendered a blank page with this thrown by the browser on the first navigation:

```
Uncaught SyntaxError: The requested module '/@fs/.../node_modules/.pnpm/dayjs@1.11.20/node_modules/dayjs/dayjs.min.js?v=…'
does not provide an export named 'default'
(at chunk-AGHRB4JF.mjs?v=…:9:8)
```

Root cause: Mermaid 11 (transitive dep of `vitepress-plugin-mermaid` shipped in #154) pulls in `dayjs`, `cytoscape`, `debug`, `@braintree/sanitize-url` — each ships a CommonJS `main` field with no `default` ESM export. Vite's dev server resolves these modules eagerly as ESM and the browser blows up before the home page renders.

The **production build was unaffected** — Rollup's plugin pipeline already wraps CJS deps for ESM consumers. `docs:build` shipped clean HTML in #154 and the CI Mermaid-fence (`grep class="mermaid"` in ADR-0009's HTML) passed precisely because it inspects the prod bundle, not the dev-server output.

## What lands

[`docs/.vitepress/config.mts`](docs/.vitepress/config.mts) — adds a single `vite.optimizeDeps.include` block:

```ts
vite: {
  optimizeDeps: {
    include: ['mermaid', 'dayjs', 'debug', '@braintree/sanitize-url'],
  },
},
```

`optimizeDeps.include` tells Vite to pre-bundle those modules through esbuild at dev-server boot, applying the same CJS→ESM interop wrapper Rollup uses in prod. The dev server now serves a working `localhost:5173` and Mermaid diagrams render.

## Notes for the reviewer

- **Why these four names specifically?** They are the Mermaid deps that ship CJS-only entrypoints. Adding `'mermaid'` alone is sometimes enough because Vite walks the dep tree, but the plugin's own README + a handful of upstream issue threads recommend listing the leaf CJS modules explicitly so the optimizer doesn't miss them on a cold cache. Cheap, defensive.
- **Why didn't the CI gate catch this?** The `Assert Mermaid renders` step in `.gitea/workflows/docs-site.yml` greps `docs/.vitepress/dist/` — the production-build output. The bug only manifests on the dev server's runtime-pre-bundling path. Catching it in CI would require booting `docs:dev` headlessly and curling the page; not worth the workflow weight for a once-per-major-upgrade class of issue. Manual `pnpm docs:dev` smoke is the right gate for now.
- **Why not bump dayjs / mermaid?** Dayjs's package shape is a long-standing upstream quirk (the `main` points at the UMD/CJS bundle); fixing it upstream would be a breaking change for non-bundler consumers. Mermaid upstream is aware; their fix has historically been "tell your bundler to pre-bundle us", which is exactly what `optimizeDeps.include` does.

## Test plan

- [x] `rm -rf docs/.vitepress/cache && pnpm docs:dev` — server boots, `curl http://localhost:5173/` returns 200.
- [x] `rm -rf docs/.vitepress/{cache,dist} && pnpm docs:build` — clean prod build in ~10 s, Mermaid SVG still present in ADR-0009's HTML (regression fence passes).
- [ ] Manual smoke: with the fix applied, navigate `localhost:5173` → home → `/decisions/0009-…` → confirm the OIDC sequence diagram renders inline, no console errors. Toggle dark mode, confirm diagrams flip theme.

julien 7579b25dfe feat(docs): vitepress site for docs/, mermaid rendering, ci build workflow (#154)
CI / commits (push) Has been skipped
CI / check (push) Successful in 2m39s
CI / scan (push) Failing after 2m31s
CI / a11y (push) Successful in 2m14s
CI / perf (push) Successful in 4m12s

## Summary

Implementation of [ADR-0022](docs/decisions/0022-docs-site-vitepress.md). Stands up the static documentation site that renders `docs/**/*.md` (architecture diagrams, daily-dev guide, ADRs, onboarding) via **VitePress + `vitepress-plugin-mermaid`**, behind a Gitea Actions build gate.

Local dev: `pnpm docs:dev`. Full build: `pnpm docs:build` (~9 s, output in `docs/.vitepress/dist/`).

## What lands

### Dependencies

`vitepress 1.6.4`, `vitepress-plugin-mermaid 2.0.17`, `mermaid 11.15.0` — workspace devDependencies. No runtime impact on `portal-shell` / `portal-admin` / `portal-bff`.

### [`docs/.vitepress/config.mts`](docs/.vitepress/config.mts)

The single source of truth for the site. Highlights:

- **`srcExclude`** drops `docs/README.md` (git/IDE-only index per ADR-0022's option A) and `docs/decisions/template.md` (authoring scaffold).
- **`rewrites`** maps `decisions/README.md` → `decisions/index.md` so `/decisions/` resolves to the curated tag-grouped landing while the source filename stays git-conventional.
- **`ignoreDeadLinks`** skips:
  - `localhost:*` URLs (Jaeger, OTLP — only resolve in a live dev session),
  - cross-repo references (`../CLAUDE`, `../../apps/**`, `../../infra/**`, `../../notes/**`) — intentional from git/IDE consumers; not the site's job to render them,
  - excluded targets (`./template`, `./README`) — file exists in the repo, just not in the site.
- **Auto-sidebar for `/decisions/`** — `adrSidebarItems()` walks `docs/decisions/00*-*.md` and emits sorted `ADR-NNNN — title` entries. Adding an ADR is a single-file change, no `config.mts` edit.
- **Hand-curated top-level nav** (Development, Architecture, Decisions, Onboarding).
- **Mermaid via `withMermaid()`** with `securityLevel: 'strict'` so diagrams can't inject arbitrary HTML.

### [`docs/index.md`](docs/index.md)

VitePress Hero landing with four feature cards (Architecture, Decisions, Development, Onboarding).

### [`docs/development.md`](docs/development.md) — two surgical fixes

- Line ~5: `[setup/](setup/)` → `[setup/01-wsl-terminal-setup.md](setup/01-wsl-terminal-setup.md)`. Folder-style links don't resolve cleanly under `cleanUrls: true`; pointing at the first onboarding page is both correct and useful.
- Line 330: wrap `${{ github.* }}` in `<code v-pre>…</code>`. VitePress runs every Markdown file through the Vue template compiler, which sees the inline `{{ … }}` as an interpolation. `v-pre` keeps the literal text intact. The rest of the source is unaffected.

### [`package.json`](package.json)

Three new scripts:

```
docs:dev      → vitepress dev docs
docs:build    → vitepress build docs
docs:preview  → vitepress preview docs
```

Pure pnpm scripts, no Nx project — the site has no cross-project dependency graph to track.

### [`.gitea/workflows/docs-site.yml`](.gitea/workflows/docs-site.yml)

Triggers on push to `main` and on PR, scoped by `paths:` to `docs/**`, `package.json`, `pnpm-lock.yaml`, and the workflow itself. Three steps:

1. `pnpm install --frozen-lockfile`
2. `pnpm docs:build`
3. Regression fence: `grep` ADR-0009's rendered HTML for `class="mermaid"` or `<svg>` so a silent Mermaid-plugin breakage on a major upgrade fails the workflow rather than ship a site with raw code blocks where diagrams should be.
4. On push only: upload `docs/.vitepress/dist/` as a `docs-site` artifact (30-day retention). The actual rsync to the static host lands when the future infrastructure ADR locks the deployment target.

### [`.gitignore`](.gitignore)

Excludes `docs/.vitepress/{cache,dist}/` so local builds don't leak into commits.

## Notes for the reviewer

- **Why `config.mts` and not `config.ts`?** VitePress is ESM-only, and `vitepress-plugin-mermaid` follows. Vite loads `.ts` config files via its CJS bundler in this workspace's setup and chokes on the ESM imports. `.mts` flips the loader to ESM and the build succeeds. Same pattern is used elsewhere in the workspace (`jest.config.cts`, app `vite.config.mts`).
- **Why no Nx project (`docs/project.json`)?** The doc site has no Nx-trackable dependencies (it consumes `.md` files, not TypeScript projects). Putting it in the Nx graph adds ceremony with no caching benefit — VitePress's incremental rebuilds are sub-second already, and the site never has cross-project `affected` semantics. Pure pnpm scripts keep the surface small.
- **Why the regression fence on Mermaid?** ADR-0022 §"Confirmation" promises it. The plugin is a community dep (sub-1.0 wrapper around the official Mermaid renderer); a major upgrade or a Mermaid runtime change could leave fenced ` ```mermaid ` blocks rendered as raw code without anyone noticing — until an RSSI clicks ADR-0009 and sees no diagram. Cheap grep gate, real signal.
- **Why upload as artifact, not deploy?** Per [ADR-0022](docs/decisions/0022-docs-site-vitepress.md) §"Deployment & CI": the host (`docs.portal.apf.fr` or a sub-path) is provisional. Locking an rsync target now would couple this PR to a not-yet-made infra decision. Artifact upload is the staging mechanism — manual drop on the host until the infrastructure ADR formalises the target.
- **Why `ignoreDeadLinks` rather than fixing every cross-repo reference?** The cross-repo links are genuinely useful from a git/IDE perspective (where the docs/ markdown is browsed alongside the rest of the codebase). Rewriting them to `https://git.unespace.com/julien/apf_portal/src/branch/main/…` would make them work on the site but lose the IDE quick-jump. Skipping at site-build time is the right trade-off — the site reader gets a graceful "link doesn't exist here" if they click, the IDE reader gets a working jump.

## Test plan

- [x] `pnpm docs:build` succeeds in ~9 s. Output at `docs/.vitepress/dist/` contains an `index.html`, every ADR, the development guide, the architecture diagrams, and the three setup pages.
- [x] Mermaid renders: `grep 'class="mermaid"' docs/.vitepress/dist/decisions/0009-…html` returns a match.
- [x] `pnpm exec nx run-many -t format:check lint test build` for the 6 main projects — 18/18 tasks green, no Nx regression from the new top-level config.
- [ ] **Manual smoke**: `pnpm docs:dev`, open `http://localhost:5173`, walk through:
  - Landing renders Hero + 4 feature cards.
  - Search box returns hits for "audit", "MFA", "OBO".
  - `/decisions/0009-…` renders the OIDC sequence diagram (Mermaid SVG, not raw text).
  - `/decisions/0010-…` ERD or `/architecture` C4 diagrams likewise.
  - Dark-mode toggle flips diagrams to dark theme without page reload.
  - Sidebar shows the 22 ADRs auto-listed under `/decisions/`.
  - The "Decisions" curated index at `/decisions/` lists ADRs by tag (no regression on the source markdown).

## What's next

Once the deployment target is fixed (future infra ADR), wire the rsync step into the workflow — that lands as a small follow-up PR. Until then the artifact carries the bundle.
