// scripts/docs/sync-wiki.mjs
// Full GitHub wiki content + cover-count sync.
//
// WHY: the wiki has no generator and historically drifts (it sat at "212+ providers /
// 14 strategies / 37 MCP tools" while code was at 226 / 15 / 87, and new docs like
// SUPPLY_CHAIN never appeared). This closes the loop: content + counts, automated per
// release by .github/workflows/wiki-sync.yml.
//
// DESIGN — update-in-place, never duplicates:
// 1. The wiki page names are hand-curated and NOT deterministically reproducible
// (e.g. "API-Reference" vs "Fly-io-Deployment-Guide"). So we iterate the EXISTING
// wiki pages and fuzzy-match each to a docs/ source by normalized key
// (lowercase, strip non-alphanumeric). When a source exists we rewrite that exact
// page → zero risk of creating a parallel/duplicate page.
// 2. A curated allowlist (NEW_PAGE_EXCLUDE) keeps internal docs (audit reports, plans,
// the docs index) off the public wiki; every other unmatched docs page is ADDED
// with a deterministic acronym-aware name.
// 3. Hand-curated pages with no docs source (Home, _Sidebar, Header, _Footer,
// Languages) are left untouched — except the four cover counts on Home.md.
// 4. EN by default. Localized mirrors (<locale>Page) are pure update-in-place and
// only touched with --include-i18n (the i18n source lags and is validated
// separately).
//
// Content transform: strip the YAML frontmatter, prepend the wiki language banner.
//
// Usage:
// node scripts/docs/sync-wiki.mjs --wiki-dir <path> # write
// node scripts/docs/sync-wiki.mjs --wiki-dir <path> --dry-run # report only
// node scripts/docs/sync-wiki.mjs --wiki-dir <path> --check # exit 1 on drift
// node scripts/docs/sync-wiki.mjs --wiki-dir <path> --include-i18n # also localized
