Every .md parsed (2,519 files, no sampling), parser carrying four controls.
400 distinct keys over 5,867 instances; 68% of notes have no frontmatter at all.
Consumption cross-referenced against 357 dataview/tasks blocks, 23 templates
and all 39 .obsidian configs: 66 keys consumed (62% of instances), 29 written
by template and read by nothing, 305 orphaned. The Compass governance block —
canonical/owner/assurance/change_log/links/related — is in the written-not-read
set on 67-161 notes each.
Method correction recorded in the report: the first template pass matched key
names anywhere in a file containing Templater syntax, which tests whether the
word occurs in prose rather than whether a template writes the key. Redone
against each template's own frontmatter block.
Inventory only — no proposed schema, per the brief.
