Compendium hygiene audit — 2026-05-25

Scanned 875 markdown files under D:/Vault/Compendium (excluding .git/, scripts/, .claude/, node_modules/, Compendium-site/, .obsidian/). Found 12087 wikilink references — 11464 resolve via Obsidian semantics (94.8 percent), 607 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, 9827 use short-path form (works, but stylistically inconsistent with the full canonical path) and 129 resolve only via slug fallback (path prefix is wrong but slug is unique — these are worth fixing). Frontmatter tag scan extracted 2040 distinct tags across 5107 tag-occurrences, with 0 likely duplicate/variant groups flagged and 1658 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: 12087
  • Resolve via Obsidian semantics: 11464 (94.8 percent)
    • Exact-path resolves: 1508
    • Short-path resolves (link uses partial path; works in Obsidian): 9827
    • Slug-fallback resolves (path prefix is wrong but slug is unique): 129
  • Dead links: 607
  • 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.

2d. Tag hierarchy candidates

Tags that look like specialisations of broader tags (heuristic: tag B contains tag A as a substring or they co-occur often). The current convention is flat — recommendation below is informational, not action-required.

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

  1. [create missing notes OR remove placeholder links] Decide on the Engineering/* cluster: 95 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.
  2. [single-file edit] Audit Sciences/Chemistry/physical-chemistry.md — 17 dead links inside (likely a comparison/reference page with stale targets). See section 1b.
  3. [multi-file sweep] Cull or merge the 1658 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.
  4. [multi-file sweep] Backfill frontmatter on the 17 notes with no --- block (mostly READMEs and Tier3 _index.md files) and the 27 notes missing a title: field. See sections 3b-3d.
