The vault is where the asset library actually lives — version-locked, named per convention, and released only to licensees who have been through the Brand Council intake. What appears on this page is the surface: a description of what the vault contains and the shape of the access pattern. The files themselves are never linked publicly.
Each volume of the book ships with a fresh access page at a private URL. That page is reached only by scanning the single-use QR pasted into the inside back cover of the physical edition, or by the link the Brand Council issues to operators over email. The access page routes to current Figma, Drive, logo suite, typeface licenses, stationery templates, and print specifications — everything an approved operator needs to produce work that conforms to the system.
This is not ceremonial gating. It is how the trust ledger keeps an audit trail of who holds which version of which asset, and why that version is the canonical one on a given date.

Six asset classes
Access: Brand Council intake
Updated per volume · PROV-B1
All icon, logo, data-viz, and layout components. Version-locked to the current volume. Master file; operators fork, they do not edit in place.
SVG, EPS, PDF, and InDesign source for every artifact the brand ships — from the seal to the stationery set to the annual report template.
Primary mark, dark and light variants, copper foil variant, proof-mark family. Each file named to the convention in section B2 below.
All three typefaces ship under the SIL Open Font License 1.1. License texts included in the vault alongside the font binaries.
Letterhead, board memo, grant letter, audit-packet cover, invoice, disbursement notice. See the Applied chapter for specimens.
Paper stock, ink recipes, binding sheet, color profiles for offset and digital runs. See section B6 for the Volume 01 specification.
The convention below is the single rule for naming any asset that carries the Provarium mark. It is fixed, it is short, and it is enforced at intake: a file named otherwise is rejected at the vault boundary and returned to the operator for re-naming. The point is not cosmetic — it is how the trust ledger finds the right version of the right asset when a claim is verified, a co-brand is approved, or an audit is filed.
Five fields, separated by underscores, all lowercase. No spaces. No date prefixes. No operator initials. Version and date are fields inside the name, not decorations on it.

The visual or functional variant — theme, channel, or role. Use the minimum disambiguator the file requires; do not stack variants unless a stacked form is the only way to distinguish the file.

Semantic version — v1_0, v2_1, v3_1 — for artifacts under active iteration. Date-stamped — 2026_04 — for dated artifacts such as annual reports or quarterly board packs. Never both.
The file extension. SVG preferred for vector artifacts. PDF for print-ready artifacts. PNG only where SVG is unsupported by the destination surface. Source files (.indd, .fig, .ai) are permitted for the working copies that live in the vault; distributed files default to SVG or PDF.
A brand system that claims to be a substrate — that claims, in the principal voice, to carry the same reconciliation discipline as the platform it governs — must be able to show its own audit trail. The change log below is that trail. Every revision to any chapter, at any level of the book, is recorded here with date, author, rationale, and reference code.
Entries are canonical. The Brand Council signs the meeting minutes that back each entry; those minutes are indexed in the trust ledger under the reference code shown in the last column. When a counterpart asks why a given claim in the book has the wording it has, the ledger is the answer.

The colophon is the book's own cover sheet — the page that answers the questions a serious reader asks about a serious artifact. Who edited it. Who designed it. Which typefaces carry its voice, and on what license. How it was printed, bound, and numbered. How many copies exist, who holds them, and under what terms they may be reproduced.
Contributor lines are left as placeholders in this edition and are filled in by the Brand Council before each print run. The council treats the colophon as it treats the book itself: a governed artifact, signed and dated at release.

The index covers every load-bearing term in Volume 01 — the vocabulary of the operating layer, the architecture of the JV, the artifacts of the brand system, and the evidence and editorial chapters that sit alongside. Each entry links to the artifact or chapter that carries the term, with anchor references where a chapter has internal sections.
Where a term is defined in the Lexicon, the lexicon entry is the authoritative definition; index references point to the contexts in which the term is used, not re-explained. Cross-references are intentional — a reader following reconciliation through the book should land, in order, on positioning, lexicon, and CFO-facing surfaces.

Volume 01 is a physical book. It is the reference copy the Principal gives to a counterpart at the end of a meeting that has earned one. It is the artifact the Brand Council signs. It is the object the vault releases assets in support of. The specification below is what the printer works to — trim, extent, paper, ink, binding, typesetting, and the rules that govern every subsequent volume.
The book is designed to reward handling. Cloth under the hand, foil where the seal lands, a ribbon that marks the reader's place in the architecture. A counterpart who receives Volume 01 should be able to feel, before they have read a line, that the JV treats its own documentation the way it asks clients to treat their governance.

These rules are inherited by every subsequent volume. A vertical-specific volume — Volume 02, the DAF sponsor vertical; Volume 03, whichever vertical follows — may change its evidence, applied, and colophon chapters, but the trim, paper family, type system, grid, and opener pattern do not change. The object is supposed to feel like a volume in a series, not a reprint of a single book with swapped text.
