Chain of custody

From the disputed line to the photograph.

Every figure the platform reports descends to individual weighings, and every weighing carries its photograph, tenant, stream, EWC code and timestamp. A recharge, a recycling rate or a compliance return can be walked down to evidence rather than argued about.

  1. INVOICE / LINE 7

    The service charge line the tenant disputes

    £3,221.42 waste recharge, one month

  2. RECHARGE RUN

    The allocation behind it

    22.4% of building waste by verified weight, five cost components

  3. STREAM TOTALS

    The weights behind the share

    1,554.4 kg across 6 streams, net of bin tare weights

  4. RECORD 908417

    One weighing among them

    8.25 kg Coffee Grounds · 16 Aug, 17:00 · EWC 20 01 08

  5. EVIDENCE

    The photograph

    the bags on the scale, the moment they were weighed

Five steps down, and the last one is a photograph. That is what dispute-proof means.

What the chain holds at each step

The reported figure

A recharge line, a recycling rate or a compliance return. Each one is computed from records, never typed in, so each one can be opened.

The allocation or aggregation behind it

The recharge run or the period aggregation, showing exactly which records were counted and on what basis.

The individual weighing

Net weight after the bin type’s tare, the tenant, the stream, the EWC code, the kiosk, the time.

The photograph

The kiosk camera photographs the disposal as it sits on the scale. The photo stays attached to the record for as long as the record exists.

Why this ends disputes instead of escalating them

An apportionment is an opinion, and opinions escalate. A record with a photograph is a fact, and facts conclude. The tenants who dispute charges hardest are the ones who have never been shown evidence, because in most buildings there is none to show.

The same chain that answers a tenant answers an auditor, an assurance provider and an inspector, because it was built once, at the point of disposal, rather than reconstructed differently for each audience.

NoteRecords are tamper-evident and permission-controlled: edits are role-restricted and logged, which is the accurate claim. Nothing here asserts records are technically immutable.
