Chain of custody in an election

A result is only as trustworthy as the record behind it. Chain of custody is the unbroken, documented trail that connects a final number back to where it came from - the primary form, the place, the person, and the time. If you cannot show that trail, you cannot defend the number. If you can, you can.

The chain, link by link

Take a single figure in a county total and walk it backwards:

• The primary record. It starts as a number written on a Form 34A and posted at the polling station, witnessed and signed in the room.
• The capture. Someone records that number - ideally with a photograph of the form itself, so the source is preserved, not just transcribed.
• The provenance. That capture carries where it happened (the station, its GPS), when (a timestamp), and who submitted it. A number with no place, time, or author is a number you cannot trace.
• The aggregation. The station figure is added into the constituency and county totals by a process you can inspect - not a black box.
• The changes. If any figure is ever corrected, the correction is logged: what changed, when, and by whom. Nothing is silently overwritten.

Break any link and the chain fails. A number transcribed without the form behind it cannot be checked against the source. An edit with no record cannot be trusted. A total you cannot decompose back into its stations cannot be defended.

Why it decides disputes

When a result is questioned, the argument is almost never about opinion. It is about provenance: show me where this number came from. A campaign or observer that captured the photographed 34A for every station, with the place and time attached, walks in with an answer. One that has a spreadsheet of numbers typed from phone calls walks in with a liability.

This is also why an append-only, tamper-evident record matters. If your own evidence can be quietly edited after the fact, it is worth less - to you, and to anyone weighing it. The strongest position is a record where every entry is preserved and every change is visible.

Building it in

Chain of custody is not a document you write afterwards. It is a property you design in from the first capture: photograph the source, stamp it with place and time and author, aggregate transparently, and log every change. It is what makes a parallel vote tabulation defensible rather than just another set of numbers.

Election Edge treats every result this way by default - each number traces to a photographed form, a station, a moment, and a person, in an append-only evidence trail. When the record is unbroken, you are not asking anyone to take your word for it. You can show them.
