> **THE READING PLAQUE.** *The Signed Zero*, draft 0.5 — made readable on
> the SX surface by its covering persona's reading grant; **a draft, not
> the published form**; started 2026-08-15 at the operator's direction
> ("I'd like to add such a reading to the SX layer") and drafted in the
> open workshop, where its construction record stands public. **The title
> stands confirmed** (the operator's naming act at the 0.2 review), **the
> grant stands by the grant word** (the operator's, 2026-08-15: "ok - that
> gets a reading grant. please go with the SX surface."), and **the 0.5
> revision — the fourth deep rung's results landed in the article — stands
> by the operator's word, 2026-08-20: "The updated reading is granted the
> reading surface."** The author is named for publication in the article
> itself: **Steven De Costa**. The register is reader-first: the
> draft-state block below is the draft's state record, not part of the
> article, and every measured claim in the article is drawn from a sealed
> public record — the procedure to verify and to re-run the experiments is
> open to any reader through the Objective Observer Initiative. The
> article's boundaries travel with it: no claim on any Millennium Prize
> problem, ever; no claim about physical cosmology, quantum mechanics, or
> consciousness. Nothing is staked by this reading; it counts no one and
> asks nothing. Covering: **starl3n** · endorsing: **Link Digital**. This
> file's sha256 is pinned in the reading register. Reading is free; the
> way across is a statement of intent (`/sx/matters`).
