Compendium hygiene audit — 2026-05-25

Scanned 867 markdown files under D:/Vault/Compendium (excluding .git/, scripts/, .claude/, node_modules/, Compendium-site/, .obsidian/). Found 11959 wikilink references — 11304 resolve via Obsidian semantics (94.5 percent), 639 dead and 16 ambiguous. Note that Obsidian wikilink resolution is path-flexible: a link like [[Engineering/foo]] resolves correctly even when the file lives at Engineering-and-Robotics/Engineering/foo.md, as long as the suffix is unique. Of the resolving links, 9781 use short-path form (works, but stylistically inconsistent with the full canonical path) and 144 resolve only via slug fallback (path prefix is wrong but slug is unique — these are worth fixing). Frontmatter tag scan extracted 2042 distinct tags across 5060 tag-occurrences, with 25 likely duplicate/variant groups flagged and 1673 tags appearing in exactly one note. Frontmatter sanity: 0 parse failures, 17 notes with no frontmatter at all, 27 missing title:, 17 missing created:, 27 missing tags:.

Helper script: System/scripts/audit-hygiene.py (stdlib only — rerun with python audit-hygiene.py to regenerate).

  • Total wikilinks found: 11959
  • Resolve via Obsidian semantics: 11304 (94.5 percent)
    • Exact-path resolves: 1379
    • Short-path resolves (link uses partial path; works in Obsidian): 9781
    • Slug-fallback resolves (path prefix is wrong but slug is unique): 144
  • Dead links: 639
  • Ambiguous links: 16

Status codes used below:

  • ok — exact relative-path match.
  • ok-shortpath — link uses a shortened path prefix (e.g. [[Engineering/foo]] instead of [[Engineering-and-Robotics/Engineering/foo]]); Obsidian resolves these fine, but you may want to canonicalise to full paths for portability.
  • ok-slugfallback — the path is wrong but the bare slug matches exactly one file; Obsidian will still resolve, but the link is misleading.
  • dead — target slug not found anywhere in the Compendium.
  • dead-path-ambiguous — exact relative path missing, slug exists in multiple locations.
  • ambiguous — bare [[slug]] resolves to more than one file.
  • ambiguous-shortpath — short-path link suffix matches multiple files.
  • empty — wikilink with no text.

1-pre. Short-path and slug-fallback resolves (informational — not dead)

These links work in Obsidian but use shortened or slug-only paths. Sorted by total per source.

Top 5 fixes, ordered by impact-per-effort:

  1. [multi-file sweep] Normalize the highest-volume tag-variant group: walkthrough, walkthroughs walkthrough. Replace in each note’s frontmatter tags: list.
  2. [create missing notes OR remove placeholder links] Decide on the Engineering/* cluster: 99 distinct dead targets under that prefix (top in cluster: [[Engineering/data-center-engineering]] referenced 4 times). Either author the missing notes or replace the links with plain text.
  3. [single-file edit] Audit Sciences/ClimateScience/ai-and-machine-learning-for-climate.md — 22 dead links inside (likely a comparison/reference page with stale targets). See section 1b.
  4. [multi-file sweep] Resolve abbreviation/full-form collisions: ml/machine-learning, rl/reinforcement-learning. Pick one canonical form per pair and rewrite occurrences.
  5. [multi-file sweep] Cull or merge the 1673 singleton tags — most are typos or one-off labels that dilute the tag space. Easiest first pass: spot-check the list in section 2c and replace obvious typos.
