NEXT WORKFLOW STAGEResponsible: Assigned Collector (Collector A (demo))

Awaiting physical intake and collection evidence

The collector must physically collect the e-waste lot, record certified scale weight, and anchor a Collection Record with scale slip hash before advancing to COLLECTED.

Integrity Gate: Mass balance and custody transfer remain locked until physical collection is anchored.

Batch Summary & Custody Assignments

Assigned actors are separated from verifier judgment. Environmental impact remains gated until independent verification and cited public factors exist.

Canonical Lifecycle & Alternative Outcomes

Five canonical happy-path stages with separate non-happy-path outcomes.

Traceability Principle: Stages 01–03 record physical custody transfer. Stage 04 is a processor self-reported claim. Stage 05 is an independently audited outcome.
  1. RegisteredREGISTEREDBatch created. Nothing has been collected yet.
  2. CollectedCOLLECTEDThe collector attests it collected the batch. Collected does not mean recycled.
  3. ReceivedRECEIVEDThe processor attests it received the batch at its facility.
  4. Processing claimedPROCESSED_CLAIMEDThe processor claims processing was done. This is a claim, not proof.
  5. VerifiedVERIFIEDThe assigned independent verifier accepted the processing claim.

Alternative Lifecycle Outcomes

Non-happy-path branches separated from the five canonical progression stages.

  • ReturnedRETURNED
    The verifier asked for additional evidence; the processor must resubmit with new evidence.
  • RejectedREJECTED
    Terminal. The verifier rejected the processing claim.
  • CancelledCANCELLED
    Terminal. Withdrawn before collection.

Evidence Records

Evidence files stay off-chain. Only SHA-256 hashes would be anchored. The values shown are placeholders, not digests of real files.

0 of 3 stage records

No evidence has been recorded for this batch yet.

Verifier Review Checklist

Current batch state is REGISTERED (review status: Not applicable).

Independent Verifier Review Checklist

Interactive demonstration checklist. Ticking items here simulates the verifier audit workflow in the client tab. No on-chain state or database row is modified without an authorized verifier transaction.

Audit criteria completed:0 of 5 (0%)
Simulated Verifier Decision Controls (Read-Only)

Actions disabled: verifier decisions are cryptographically enforced on-chain (D-15). Only the assigned verifier key may record a state transition.

Verification, return, and rejection can only be performed by the batch's assigned, independent verifier through the registry contract. This page has no such control and is not connected to the contract.
