The Register · The Trust & The Bridge

The Register is the only evidence of adoption of the Bridge. It is an append-only file, register.jsonl, one entry per line, validated against schema.json. No entry is ever edited or removed; a mistake is corrected by a later entry that names the one it supersedes.

The Register is empty. No party has adopted the Bridge. An empty Register is the current state of the world: any claim of adoption or endorsement that is not on this page is false.

Worked example (not an entry)

The following is shipped with the schema so that a submitter can see the shape of a real entry. It is marked "example": true, names no real party, carries no real signature, and is not on the Register.

Entry types

Each type corresponds to something Article 11.1 of the Bridge says the Register holds.

declaration: A party adopts named Articles for named covered systems, naming its verifier, weight custodian, key custodian and auditor (Article 14.1).
threshold: The thresholds a party applies under Article 3, the method, and the status of each system against them (Article 3.3).
modification: A material Modification disclosed before production effect, or a weekly aggregate of sub-material updates (Article 5.2).
incident-initial / incident-full: Initial report within seventy-two hours of detection; full report within sixty days (Article 6.2).
withholding: A withholding under Article 5.4: its ground, category and expiry, never its content.
verifier-finding: A verifier's published finding (Article 4.7), or a finding or refusal under Article 8.2.
annual-verification: The joint finding of auditor and verifier (Article 10.1), including the share withheld (10.3); a renewal under Article 14.3.
lapse: An adoption recorded as lapsed (Article 14.3).
correction: Corrects an earlier entry, which stays visible and is marked superseded (Article 11.2).

Status of this Register

Article 11.2 requires the Register to be held by not fewer than three unaffiliated custodians, at least one a public institute or non-profit not developing covered systems. This copy is held by one custodian, this repository and its mirrors, and is offered as the plain-form publication Article 11.3 describes. Until three custodians hold it, that shortfall is itself part of the current state of the world.
