Silver streaks: evidence comparison

Describe the mark first. Keep candidate causes separate from observations; use the relevant grade, process, and inspection requirements.

Job and observation

Part + revision / press / mold / exact grade + lot / cavity / location + extent / collection time / inspected + affected counts

Visual evidence

Inspection reference / sample IDs / overview + detail image references / gate and orientation / consistent viewing conditions / classification uncertainty

Material-moisture question

Requirement + method / sample result, units, location, time / drying, loading, and transfer references / relation to affected parts

Thermal-history question

Stops + restarts / relevant material-processing history / setpoints separately from actual readings / measurement locations / missing evidence

Local-flow or tooling question

Pattern by gate, path, and cavity / sample comparisons / process record / relevant tooling findings or inspection request

Comparison and limits

Before/after groups / all changed conditions / defect response / other required checks / supported conclusion and unresolved alternatives

Next request / ownership

Specific missing evidence / responsible person + review time / trial reference if approved / sample and product status
