Office surface · desktop-first · synthetic demo

Custody, evidence and credit — three records, never one badge.

The office desk keeps the physical part, the supplier checklist and the money in separate panels so a posted credit can never quietly close a custody question.

Panel 1 · Case and evidence

What is proven

  • Evidence Confirmed · 3 of 4 checks
  • Unresolved Replacement part label unreadable
  • Policy Acme v3 · effective 2026-08-01 · source attached

Panel 2 · Return and custody

Where the part is

  • Custody Office bin · reported by lead technician
  • Instruction Return required · supplier guide p.2
  • Deadline Ship by 2026-09-30 · America/New_York

Hold means hold

Panel 3 · Credit

What is verified

  • Vendor decision Partially approved · USD 212.50
  • Posted credit Verified
  • Unallocated USD 100.00 visible separately

A credit arriving does not mark evidence complete or authorize disposal.

Illustrative ledger — synthetic figures

The numbers below are made up to show the semantics. They are not customer data, not a promise of recovery, and not a projection.

Case 0042 remaining62.50Expected 212.50 minus allocations and approved write-offs.

Expected credit, vendor-approved credit and verified posted credit are different facts. An allocation records a link, not a payment, and credit offsets are not cash deposits or incremental profit.

The allocation drawer

Before confirming

  • Supplier, account and currency are shown with the source memo.
  • Total verified, already allocated and remaining capacity are stated.
  • Candidate case balances are listed; the user selects targets and amounts explicitly.
  • The sum preview updates deterministically from the chosen entries.

At confirmation and reversal

  • Confirm restates the total and says plainly: this records an allocation, not a payment.
  • Cross-supplier and cross-currency matches are refused, never reconciled silently.
  • Reversal shows the downstream cases and takes a reason before it commits.
  • Posted records are append-only; corrections are signed reversal-then-new-allocation events.

Deadlines keep their type

A ship-by date is not a receive-by date. The deadline type, date, timezone and source are stored together; an unknown vendor deadline asks for confirmation instead of inventing a countdown.

Reminders at 7, 3 and 1 day before a confirmed deadline are advisory. They never change the underlying date, and email is never the only deadline control.
