Read coverage before treating a related set as the answer to a factory decision. LotTrail reports admitted evidence within selected sources, permissions, time boundaries and traversal limits. It does not infer missing genealogy or guarantee that an empty result means unaffected.
Check the declared boundary
Confirm source instance and generation, scope, selected datasets, relationship mode, direction and local evidence cutoff. Read the source's sequence and occurrence-time coverage and its completeness declaration.
A completeness declaration is the source owner's claim. Missing sequences, unknown sequence information, incomplete capture, held or conflicting evidence, pending replacement and traversal limits can still make the result partial. A source that never recorded a relevant relationship cannot prove that the relationship did not exist.
Distinguish relationship meanings
Recorded physical relationships and associations answer different questions. A kit check is not consumption. A completed procedure is not automatically a manufactured output. A label submission is not physical label output. A booking is not actual shipment contents or despatch.
A local reviewed identity bridge states that two exact references identify the same item. It does not create a manufacturing event or merge away the original source identities. Inspect its review provenance separately from physical relationships.
Grouped split, merge, transformation or rework operations can expose potential downstream or upstream branches. Do not derive material allocation from the number of outputs or source quantities. Quantities remain exact declared decimal strings and units, without sums, conversion or inferred fractions.
Explain time correctly
Occurrence time says when the source reports an event happened. Local evidence sequence says when it became known to LotTrail. A late-recorded shipment with an older occurrence time can appear in a new current result while remaining absent from an earlier saved report.
As-known views retain the local cutoff; current permissions still apply. A current correction can deactivate wrong evidence while its replacement remains missing and explicit.
Hand over bounded conclusions
Report the exact run identity, question, related set and relevant limitations. Say which additional evidence or permission is needed. Do not describe a partial result as an exhaustive recall list or use a missing seed as proof of safety.
Operational source owners decide physical containment, stock or quality actions through their own products and procedures. Use cases to record the local review and corrections when source evidence must change.
