Material Traceability
Evidence Ledger · Circular Industry“Collected does not mean recycled.” Environmental impact claims remain strictly gated until physical custody evidence and mass balance are independently verified.
Custody & Verification Pipeline
Every transition requires specific physical evidence. Stages 01–03 track physical custody; Stage 04 is a self-reported claim; Stage 05 is an audited outcome.

Non-linear state paths: returns require evidence rectification; rejection is terminal- Returned1
RETURNEDThe verifier asked for additional evidence; the processor must resubmit with new evidence. - Rejected1
REJECTEDTerminal. The verifier rejected the processing claim. - Cancelled1
CANCELLEDTerminal. Withdrawn before collection.
Review Status Disambiguation: Pending verifier review (1 batch) is a derived status of batches in PROCESSED_CLAIMED, not a distinct lifecycle stage.

Impact Gate (D-08): Environmental impact credits remain strictly unavailable until a batch is VERIFIED with complete evidence and cited public factors. No impact figures are estimated or shown.
Unreconciled Claims Queue
Batches requiring verifier audit or processor rectification.
Awaiting independent verifier attestation and evidence review.
INSUFFICIENT_EVIDENCE: Evidence does not cover the claimed processing.
EVIDENCE_INCONSISTENT: Evidence contradicts the claim or other records.

- DEMO-002 · Processing claimed
Processor submitted its output set and processing evidence.
Processor B (demo)
- DEMO-002 · Pending verifier review
Review status, not a lifecycle stage. The batch remains in PROCESSED_CLAIMED until the assigned verifier acts.
Verifier C (demo)
- DEMO-004 · Returned for more evidence
Verifier returned the claim. The processor must submit new evidence before resubmitting.
Verifier C (demo)
- DEMO-004 · Awaiting resubmission
Review status. Waiting for the processor to resubmit with new evidence.
