Generate comprehensive health report for the vault.

Context

Config: @_core/config.yaml

Session Task Progress

TaskCreate: "Scan vault files"
  activeForm: "Scanning vault files..."

TaskCreate: "Check links and orphans"

TaskCreate: "Generate health report"
  activeForm: "Generating health report..."

Processing Steps

1. Scan Vault

   • Glob all .md files
   • Exclude: _core/, _templates/, _archive/

2. Check Broken Links

   • Extract all [[wikilinks]] from each file
   • Verify each target exists
   • Report: source → broken target

3. Find Orphan Notes

   • Notes with no inbound links
   • Exclude: index files, standalone: true

4. Check Missing Sections

   • Typed notes (doc, decision, blocker, meeting) should have ## Links
   • Report missing required sections

5. Calculate Statistics

   • Notes by type
   • Notes by project
   • Link density (links per note)

6. Check Synthesis Freshness

   • For each 01-index/{project}.md, check if ## Synthesis section exists
   • If synthesis is missing or says "No synthesis yet", flag as stale
   • Check vault log (01-index/_vault-log.md) for last index-regen entry per project
   • If no regen in 7+ days, flag as stale

7. Check Update Status

   • Read VERSION file for local version
   • Query GitHub API for latest release: curl -sS "https://api.github.com/repos/{repo}/releases/latest" (non-fatal on failure)
   • Compare: "Up to date" | "Update available: vX → vY" | "Could not check"

8. Append to Vault Log

   • Append health entry to 01-index/_vault-log.md (see .claude/rules/vault-log.md)

9. Generate Report

   • Write to 01-index/_graph-health.md
