Health-check wiki for inconsistencies

Scan wiki health: contradictions, orphans, stubs, stale claims, broken links

Periodic health check of a wiki to surface decay (orphans, broken links, stubs) without auto-fixing

• · wiki/ directory with markdown pages
• · Frontmatter on pages (evergreen flag, ingested_at timestamp)

• · Lint report at wiki/lint-reports/YYYY-MM-DD.md
• · Log entry appended to wiki/log.md with issue count and critical summary

• · Read (all wiki/*.md files)
• · Write (wiki/lint-reports/**, wiki/log.md)
• · Bash (grep for links, page count, term frequency)

• · wiki/ directory with markdown pages
• · wiki/lint-reports/ and wiki/log.md can be created
• · Pages use [[PageName]] link syntax

• · wiki/ directory does not exist
• · grep or file I/O fails on large wiki
• · Inconsistent frontmatter format across pages

• · Distinguishes orphans (no inbound links) from stubs (< 50 words)
• · Detects stale claims (sources > 180d old without evergreen flag)
• · Checks index drift (pages missing from index.md)
• · Report is read-only, user decides action per item
• · Logs critical counts (contradictions, broken links) for quick scanning
