Batch DEMO-002

PROCESSED_CLAIMEDProcessing claimedReview status: Pending verifier review

Mixed small electronics (demo)

Synthetic demo data. Not connected to a backend, database, or blockchain. Names, times, masses and hashes below are invented.

Recorded Intake10.0 kg (10,000 g)
Claimed Output9.0 kg (9,000 g)
Last Updated (UTC)
NEXT WORKFLOW STAGEResponsible: Independent Verifier (Verifier C (demo))

Action Required: Independent verifier audit pending

The assigned independent verifier must audit evidence integrity, review mass balance sheets, and anchor an on-chain decision: VERIFY, RETURN, or REJECT.

Integrity Gate: Independent verifier must be distinct from both collector and processor (STATE_MACHINE rule 3).

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 Withdrawn before collection.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.

Verifier Review Checklist

This batch is in PROCESSED_CLAIMED with review status: Pending verifier review.

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.

Event Timeline

Chronological log distinguishing on-chain lifecycle transitions from derived review-status updates.

5 events
  1. RegisteredLifecycle transition

    Batch registered with assigned collector, processor and verifier.

  2. CollectedLifecycle transition

    Collector recorded intake mass and collection evidence.

    Collector A (demo) ·

  3. ReceivedLifecycle transition

    Processor recorded receipt evidence.

    Processor B (demo) ·

  4. Processing claimedLifecycle transition

    Processor submitted its output set and processing evidence.

  5. Pending verifier reviewReview status

    Review status, not a lifecycle stage. The batch remains in PROCESSED_CLAIMED until the assigned verifier acts.
