called out warning reminder

Fiduciary does not mean trustworthy. It means holding a thing on another party’s behalf, under an enforceable duty to them.

We have a word for the property of a record. Evidentiary. We have never had one for the duty owed about it.

eviduciary (n., adj.) From evidence + Latin fiduciarius, "held in trust." One who holds evidence in trust for another, under an enforceable duty to the party the evidence serves. The role is to records what a fiduciary is to funds: custody without ownership, duty without interest.

A signed chain proves a record was not altered. It cannot prove the holder is neutral, because neutrality is not a mathematical property. It is a duty, and duties belong to roles.

The five duties

Custody. Hold it, keep it available, keep it intact. Failure to produce is a breach.
Non-alteration. Cannot modify it, and provably cannot.
Non-inspection. Holds without reading. The custodian has the box, the beneficiary has the key, neither opens it alone.
Production on the beneficiary’s instruction only. Nobody else’s say-so opens it.
Disclosure of compromise or compulsion. Must say if the record is incomplete, if custody was breached, or if production was compelled elsewhere.

Who cannot hold it

Not a judgment of character. A property of position.

The vendor whose machine did the work, because they are the audited party. Anyone with an interest in the record’s contents. And any firm, for its own engagements: a firm can be a fine eviduciary for its clients and never one for itself.

Offered freely

This is a category, not a brand. No trademark has been filed and none will be, by me. Searched the US federal register on 31 July 2026, exact and stem and every historical coinage, dead marks included. Clean.

Take the role, implement the duties, put the word on your service. It only matters if more than one party can hold it, the same way fiduciary only matters because nobody owns the word.

Nothing here is a new cryptographic primitive. It is a governance role on top of primitives that already exist, it does not prove when something was written, and borrowing fiduciary’s shape is a design move rather than a legal claim.

The name has a date now. Build from it.
