Operational evidence guide
Trace the physical object, decision, and proof across every handoff.
Traceability is more than a timeline of statuses. Identity, custody, quantity, location, task, executor, command, package, movement, milestone, exception, evidence, and cost must remain queryable as one connected story.
Evidence chain
Follow what moved and why.
Identity → physical work → custody → proof → finance
SKU, merchant alias, barcode, lot, serial, expiry, packaging, owner.
Handling unit, quantity, location, quality, hold, reservation, count.
Task, operator or robot, station, scan, command, acknowledgement, completion.
Carton, pallet, label, tracking, leg, stop, load, tour, custody.
Milestone, confidence, exception, photo, signature, document, POD.
Quote, charge, invoice, payment, carrier cost, claim, settlement, margin.
Questions the model must answer
Can an investigator move in both directions?
Where did this lot go?
Find transformations, handling units, allocations, orders, packages, shipments, consignees, delivery evidence, holds, and open exposure.
What produced this shipment?
Trace package contents, picks, source locations, lots, receipts, supplier, ASN, inspection, and product mapping.
Why did execution stop?
Read rule, current state, reason, affected objects, authorized next action, owner, timestamp, and audit.
Why was this amount billed?
Move from invoice line to rate rule, source work, quantity, shipment, evidence, reviewer, adjustment, and payment.
Integrity tests
Prove that correlation survives failure and correction.
One business result.
Retry the event and retain the same outcome without deleting the second attempt.
Preserve sequence and source.
Do not let a lower-confidence late milestone overwrite stronger proof silently.
Link before and after.
Retain actor, reason, original value, corrected value, affected objects, and downstream reconciliation.
Command is not completion.
Keep mission intent, vendor exchange, watchdog, physical observation, recovery, and task state distinct.
Preview before hold.
Identify affected stock, handling units, orders, shipments, locations, and exclusions before action.
Verify outside the platform.
Check schemas, row counts, hashes, entity links, and representative imports independently.
Route and custody
Do not flatten a movement into one tracking number.
Stops, legs, modes, executors, equipment, planned and actual times, custody handoffs, and evidence remain ordered on the transport graph.
- Partner fleet or external-carrier executor per leg.
- Handling units and packages linked to movement.
- Milestone source, confidence, and correction lineage.
