Status Lines
A controlled vocabulary of bolded, dated status lines that make any stateful document declare whether it is current, preserved, or retired.

Problem it removes
A repository accumulates documents whose commands still work but whose claims are historical. Without a marker, every reader must infer from context whether a profile, runbook, or measurement is active — and a confident-looking stale document is exactly the one that gets acted on.
Mechanism
The bolded first line after every stateful document’s H1 carries a leading controlled term, a role qualifier, and a dated verb clause:
**Status: CURRENT production deployment.** Observed 2026-01-01 12:00 UTC
after <the observation that supports the claim>.
The vocabulary is small and closed — CURRENT, PRESERVED, VALIDATED, PARKED, RETIRED — with two operating rules: check the status line before treating any document as active, and never rewrite preserved measurements — displacement changes only the status line and adds a dated clause. When an index lists the documents, it carries a shorter parallel marker, which a machine check can hold in agreement with the document (see Governed Read).
Cost
Authoring: minutes per document. Per change: one line edited at every real state change — which is the point; the edit is the record. Per session: none; the line is read where the document is read.
Do not adopt when
Documents in the repository have no lifecycle — nothing is ever displaced, so every status line would read CURRENT forever.
Evidence
Assessed in inference-ops and cloud-ops, where the governed read asserts status lines against the current projection.

Typed Current Projection declares which document should carry CURRENT, making the marker checkable. Frozen Archive is where fully retired material goes.
